On the 2009-2019 RAM 1500 5.7L HEMI, the 5.7L HEMI engine with Multi-Displacement System (MDS) can experience premature lifter and camshaft wear. The MDS deactivation lifters are prone to failure, causing ticking, misfires, and in severe cases, camshaft lobe damage. This issue has led to class action lawsuits.
Common Symptoms
Ticking noise at idle
Engine misfire codes P0300-P0308
Check engine light
Loss of power
Rough idle
Tick worse when cold
How to Fix
For early detection: Use quality synthetic oil and change every 5,000 miles. Install an MDS delete kit ($200-400) to prevent future failures. If lifters have failed: Full lifter replacement with non-MDS lifters ($2,000-3,500). If camshaft is damaged, expect $3,500-5,500 for full repair. Consider a tuner to disable MDS electronically.
Owner tips & cautions
TipDIY repairs can save significantly - dealer charges $200-400 but DIY costs are typically 50-70% less

On the 2003-2008 RAM 1500 5.7L HEMI V8 (Eagle predecessor), on 2003-2008 5.7L HEMI engines the cylinder-head valve-seat bores were machined without sufficient interference fit. Combined with localized coolant boiling and hot spots in the heads, an exhaust or intake valve seat can spin loose and drop into the combustion chamber. When the seat drops it is hammered by the valve and piston, causing a sudden misfire, loss of power, a heavy metallic knock, and in many cases destruction of the piston, valve and head. This is distinct from the well-known exhaust-manifold-bolt tick and the later MDS lifter/cam failure; it is a structural cylinder-head defect specific to pre-2009 (pre-Eagle) HEMIs. Overheating events dramatically raise the risk. The 2009 Eagle HEMI revision used improved seat material and tighter machining and largely eliminated the failure.
Common Symptoms
Sudden single-cylinder misfire (P0301-P0308)
Loud metallic knocking or clattering
Significant loss of power
Rough idle and shaking
Check engine light flashing
History of an overheating event before failure
How to Fix
There is no patch repair for a dropped seat. The affected cylinder head (often both) must be replaced or rebuilt with upgraded seats; if the piston or valvetrain is damaged, a long-block or complete engine replacement is required. Owners keeping a pre-2009 HEMI should avoid overheating, maintain the cooling system rigorously, and address any cooling-system weakness or persistent misfire (P0301-P0308) immediately. When replacing one head, many shops replace both heads plus the timing set and oil pump, which are also known weak points on this engine family.

On the 2013-2024 RAM 1500 3.6L Pentastar V6, on the 3.6L Pentastar V6, the needle bearings inside the roller rocker arms fail, letting the rocker go loose and hammer/score the camshaft lobe. This produces a distinct top-end tick ('Pentastar tick') and, if left, camshaft damage and misfires. It is a widely reported failure across Ram 1500, Wrangler, Grand Cherokee, and Durango; Chrysler revised the rocker part several times to improve needle-bearing durability, so a repeat failure is common if an outdated rocker is installed.
Common Symptoms
Ticking/tapping from valve cover area
Check engine light
Random misfire
Rough running
Loss of power
How to Fix
Remove the valve cover and inspect rockers for play and cam lobes for scoring. Replace failed rocker arms (both intake and exhaust as needed) with the latest-revision part, and replace the camshaft if lobes are scored. Because debris circulates, inspect lifters/lash adjusters and change oil. TSB 09-002-14 REV. B addresses P0300 from excessive cylinder leakage that may require left cylinder head replacement. Always use the newest rocker revision to avoid a repeat.

On the 2014-2023 RAM 1500 3.0L EcoDiesel V6 (VM Motori A630), the 3.0L EcoDiesel V6 suffers documented bottom-end failures: the main bearings (most common) and connecting-rod bearings wipe out, dropping oil pressure to the rods, spinning a rod bearing and sometimes snapping the crankshaft if driven on. Factory main-bearing clearances are very tight (~0.0015 in), so the combination of high load at low rpm, torsional vibration, and hot thin oil wipes a bearing. A contributing failure is the plastic-bodied oil cooler/check valve, which can fail under sustained high oil temperature (especially towing) and contaminate the oil — accelerating bearing damage. These are catastrophic, often-low-mileage failures distinct from the previously covered EGR-cooler and CP4 fuel-pump issues.
Common Symptoms
Low oil pressure warning
Deep knocking/rumble from the bottom end
Metal shavings in the oil
Sudden engine seizure or no-start after a knock
Oil in coolant or coolant in oil (oil-cooler failure)
How to Fix
At the first sign of low oil pressure, a deep knock, or metal in the oil, stop driving — continuing destroys the crankshaft. Repair requires a short-block/engine replacement or full bottom-end rebuild with new bearings. Preventively: change oil on a shorter interval with the correct spec, avoid lugging the engine at low rpm under heavy load, monitor oil pressure/temperature when towing, and address oil-cooler leaks promptly to prevent oil contamination.

On the 2002-2009 RAM 1500, the 4.7L PowerTech V8 is intolerant of overheating and neglected coolant. Head gaskets leak combustion gases into the cooling system (air in coolant, coolant pushed from the overflow, steam/coolant smell from the exhaust on cold start). Once the aluminum heads warp or a corrosion channel opens between a water jacket and a cylinder, the machined-in valve seats can drop, causing catastrophic misfire and internal damage. A block/combustion-gas test in the coolant confirms it.
Common Symptoms
Coolant loss with no visible leak
Air/bubbling in cooling system, coolant pushed from overflow
White steam or coolant smell from tailpipe on cold start
Overheating
Rough idle / misfire after an overheat event
Milky oil in severe cases
How to Fix
Do a combustion-leak (block) test to confirm. Fix requires head gasket replacement with resurfaced or new cylinder heads (dropped valve seats mean a rebuilt/new head, not just a gasket). Use a Mopar/Fel-Pro MLS head gasket set and always replace the thermostat, water pump and radiator, and flush the cooling system on schedule to prevent recurrence. Parts+labor typically $1,500-$3,500 depending on head damage.

On the 1994-2001 RAM 1500, on Magnum-engine Rams the intake manifold has a stamped-steel plenum pan sealed to the aluminum manifold by a one-piece gasket. Because steel and aluminum expand at different rates, the gasket tears over time and lets engine oil from the lifter valley get drawn into the intake plenum and burned. Virtually every high-mileage 3.9/5.2/5.9 Magnum develops this. Burned oil fouls the oxygen sensors, causes detonation (pinging), and can destroy the catalytic converters if ignored.
Common Symptoms
Excessive oil consumption with no external leak
Sudden loss of fuel economy
Pinging/detonation under load
Rough running and low power
Blue smoke / oil pooled in bottom of intake plenum
Fouled spark plugs and O2 sensors
How to Fix
Remove the intake, discard the OE stamped plenum pan and install an aftermarket billet/thicker steel plenum repair plate with a new gasket (commonly sold as a 'plenum repair plate kit', e.g. from plenumrepairplate.com), or install a Mopar/Fel-Pro intake gasket set (Fel-Pro MS 90314 series plenum/valley gaskets). Inspect and replace fouled O2 sensors afterward. DIY parts run roughly $60-$180 (gasket/plate kit); shop labor adds the rest.

On the 2014-2023 RAM 1500 5.7L HEMI V8 (Eagle, with MDS), the 5.7L HEMI (Gen III) with the Multi-Displacement System (MDS) is well documented for roller-lifter failure that progresses into camshaft lobe damage. The MDS deactivation lifters and the engine's circuitous oiling path (oil routed through the deck, head gasket, and rocker shaft to the lifter bore) leave lifter bores oil-starved at low RPM. Improperly hardened lifter roller/needle assemblies allow needles to breach the surface hardening, spalling the roller and then wiping the cam lobe. It starts as a rhythmic cold-start/idle tick and can end in metal debris throughout the engine and total failure, sometimes at very low mileage. This is the subject of the Petro et al. v. FCA US LLC class action (D. Del., No. 1:22-cv-00621) covering 2014+ 5.7L and 6.4L HEMI engines. FCA revised the lifter design around 2018 (larger needles) but failures continued to be reported afterward.
Common Symptoms
Rhythmic ticking/tapping at cold start and idle
Tick that changes with RPM or comes and goes with MDS engagement
Loss of power or misfire as cam lobe wears
Metal debris/glitter in the oil
Check engine light, eventual rough running or no-start
How to Fix
Diagnose the tick with a stethoscope to rule out exhaust-manifold leaks vs. internal valvetrain. Confirmed lifter/cam failure requires replacing all 16 lifters, the camshaft, and often rockers/pushrods (and inspecting MDS solenoids). Many owners delete MDS during the repair. Stay on top of oil changes with the correct spec and avoid extended oil-change intervals; some run a slightly heavier oil to mask early tick. Document the failure for the class action if eligible.

On the 2009-2019 RAM 1500 5.7L HEMI, the exhaust manifold bolts on HEMI engines are prone to breaking due to heat cycling. Broken bolts cause exhaust leaks, ticking noise on cold start, and potential exhaust smell in cabin. The rear bolts on both sides are most commonly affected.
Common Symptoms
Ticking noise on cold start
Exhaust smell in cabin
Visible exhaust leak at manifold
Tick goes away when warm
Failed emissions test
How to Fix
Replace broken bolts with upgraded stainless steel manifold bolts ($50-100 for kit). If studs break off in the head, extraction may be needed ($200-500 at shop). Some owners upgrade to headers which eliminates the issue entirely ($800-2,000). Apply anti-seize to new bolts during installation.

On the 1994-2001 RAM 1500, the 3.9/5.2/5.9 Magnum uses a camshaft position sensor inside the distributor plus a crankshaft position sensor on the bell housing. These sensors are heat-sensitive and fail intermittently — the engine stalls or dies when hot and refuses to restart until it cools, or cranks-but-won't-start with no other symptom. Corroded/loose sensor connectors cause the same behavior.
Common Symptoms
Stalls when hot, restarts after cooling
Cranks but won't start
Intermittent dying while driving
Rough idle before failure
Tach drops to zero at stall
How to Fix
Inspect the sensor connectors/wiring for corrosion or a pulled pin first. Replace the failing sensor with a Mopar unit (owners report frequent failures of cheap aftermarket sensors): camshaft (distributor pickup) sensor Mopar 56027868 and crankshaft position sensor 56027865 (verify by engine/year). On distributor-cam-sensor trucks a full distributor may be needed if the pickup is integral. Parts $30-$150; typical $50-$250.

On the 2025-2026 RAM 1500, early-production 2025 RAM 1500 trucks equipped with the new 3.0L Hurricane twin-turbocharged inline-six (Standard Output 420 hp and High Output 540 hp) are widely reported to throw check-engine lights and random/multi-cylinder misfire codes, often on cold start or under load in hot weather. Owners on the 5thGenRams and RamForum communities report P0300 (and per-cylinder P0301-P0306) within the first few thousand miles. Stellantis has issued multiple software TSBs (e.g., 08-055-25 for HO, 08-031-25 for SO, and a cold-start update) that reflash the ignition system control module (ISCM) and PCM; a separate TSB (09-025-25) addresses a purge-line/vacuum-leak source of lean misfires. This is a new-engine, new-generation problem outside the existing HEMI-focused coverage.
Common Symptoms
Check engine light
Engine misfire / stumble
Rough idle
Hesitation under acceleration
Misfire codes on cold start
How to Fix
Have the dealer apply the latest ISCM/PCM software per the applicable misfire TSB (HO vs SO calibration). Inspect and reseat the EVAP purge line and the air-intake hose at the airbox for vacuum leaks (TSB 09-025-25). Many owners report running 91+ octane reduces misfire events in hot weather. If reflash and vacuum-leak repairs do not resolve it, dealer should diagnose ignition coils/injectors under powertrain warranty.

On the 2009-2024 RAM 1500, on the RAM 1500, P0011 is overwhelmingly a Variable Valve Timing (VVT) fault on the 5.7L Hemi, and secondarily on the 3.6L Pentastar V6. The Hemi uses a single central cam phaser fed oil pressure through one oil control valve (the VVT solenoid, mounted at the front of the engine near the timing cover). The PCM commands the phaser to a target intake-cam angle and monitors the actual angle via the cam/crank sensors. When the solenoid's fine oil screen clogs with sludge/varnish, or the solenoid sticks, oil flow to the phaser is no longer regulated and the intake cam advances past the commanded position — the PCM flags P0011 (over-advanced, bank 1). The root cause is almost always oil-related: extended oil-change intervals, low level, or off-spec/thick oil that will not flow through the small VVT passages, especially on cold starts. On higher-mileage Hemis, a P0011 (often alongside P0016/P000B) can also be the leading edge of the well-known Hemi cam/lifter wear failure — wear metal contaminating the oil seizes the phaser and solenoid, so P0011 should not be dismissed as 'just a solenoid' on a ticking, high-mileage engine.
Common Symptoms
Check engine light with stored P0011
Rough idle / occasional stumble, especially at cold start
Slightly reduced fuel economy
Hesitation or lack of power under acceleration
Ticking noise (on higher-mileage Hemis where cam/lifter wear is involved)
Hard start or brief rough running on cold mornings
How to Fix
Start with the cheap, high-yield steps: verify oil level and do a fresh oil-and-filter change using correct-viscosity oil (5W-20 on the Hemi), then clear the code and retest — dirty/degraded oil is the single most common trigger. If P0011 returns, replace the VVT/oil-control solenoid (clean the screen or renew), and perform the required cam/crank relearn afterward. If codes persist after a new solenoid, or the engine ticks and has high mileage, inspect the cam phaser, timing chain/guides and — critically on the Hemi — the camshaft lobes and lifters (MDS lifters), since VVT timing codes frequently accompany the cam/lifter failure. On the 3.6 Pentastar, also confirm the oil-filter-housing/cooler is not leaking and starving oil pressure.

On the 2009-2016 RAM 1500, the TIPM controls most electrical functions and commonly fails, causing erratic behavior. The fuel pump relay inside the TIPM is particularly prone to failure, resulting in no-start conditions. Horn honking randomly, headlights flickering, and wipers activating on their own are common symptoms.
For fuel pump relay failure: Install an external bypass relay kit ($30-50 DIY) to power fuel pump directly. For complete TIPM replacement: Use remanufactured unit ($400-600) or new OEM ($800-1,200). Some electrical shops can rebuild existing TIPM for $200-400. Warranty lawsuit settlements may cover repairs for some VINs.

On the 2011-2018 RAM 1500, the Totally Integrated Power Module (TIPM) contains a fuel-pump relay soldered to its circuit board. When it fails it cuts power to the fuel pump, causing a crank-no-start that mimics running out of gas, or a sudden stall while driving; sometimes the pump keeps running with the key off and drains the battery. The relay is non-serviceable inside the module, making this a well-known and expensive Chrysler/Ram electrical failure across 2011-2018 trucks.
Common Symptoms
Crank but no start (acts out of fuel)
Random stalling while driving
Fuel pump runs with key off / battery drain
Intermittent no-start
Multiple electrical gremlins
How to Fix
Confirm by monitoring fuel-pump power/relay operation. Options in ascending cost: install a fuel-pump relay bypass cable or plug-in external relay, or install Chrysler's external fuel-pump relay relocation kit (Mopar 68142156AA) to move the relay out of the TIPM. If other TIPM circuits are also faulty, replace/rebuild the TIPM (must be programmed to the VIN). Specialty shops repair the original board for far less than a new module.

On the 2025-2026 RAM 1500, rAM recalled 2025-2026 RAM 1500 pickups equipped with the 12-inch digital instrument panel because a software error can make the cluster go completely blank either at startup or while driving, hiding the speedometer, gear-selection indicator, and all warning lights. NHTSA campaign 25V826000 (Nov 30, 2025) covers roughly 43,000+ trucks built Oct 2023-Nov 2025 with Marelli-supplied clusters; a follow-up campaign 26V225000 (Apr 2026) addresses the same blank-display condition. A malfunction indicator may briefly illuminate before the screen blanks. Loss of the cluster increases crash risk and is not the same as the older Uconnect infotainment freeze already in our data.

On the 2019-2025 RAM 1500, the 2019+ RAM 1500 with eTorque mild hybrid system (standard on V6, optional on V8) experiences failures of the 48-volt battery pack, belt-driven motor generator (BDM), and eTorque control module. Symptoms include rough idle, stalling at stops, auto start-stop not working, and "Service eTorque System" warning messages. The 48V lithium-ion battery pack located under the rear seat deteriorates over time, especially in hot climates. TSB 08-074-20 REV.A addresses eTorque motor generator unit noise and vibration. Replacement of the 48V battery pack costs $800-1,500 and the BDM unit runs $1,200-2,000.
Common Symptoms
Service eTorque System warning message
Auto start-stop system not functioning
Rough idle or stalling at stops
Vibration or shudder during restart
Check engine light with P0AA6 or U1466 codes
Reduced fuel economy
Clicking or grinding noise from belt-driven motor
How to Fix
Diagnose with a Mopar wiTECH scan tool to identify if the 48V battery, BDM, or control module is at fault. Check TSB 08-074-20 REV.A for motor generator noise. If the 48V battery is degraded (below 42V resting), replace the battery pack under the rear seat ($800-1,500). If the BDM is failed, replace the unit and serpentine belt ($1,200-2,000). Software reflash may resolve intermittent issues. The eTorque system is covered under the powertrain warranty (5yr/60k miles).

On the 2019-2024 RAM 1500, the optional 12-inch portrait Uconnect 5 display (Android Automotive) on 5th-gen DT Ram 1500 trucks fails in several ways distinct from the older 8.4 Uconnect freeze/reboot issue. Owners report the screen going completely black/blank and not turning on, vertical lines across the LCD, and visual artifacts. Some failures are LCD-panel hardware (heat/age driven), others are software (memory leaks, failed updates, process crashes) that produce a frozen or black display. Because radio audio sometimes still works via steering-wheel controls, the fault is clearly the display/head unit rather than the speakers. Dealers typically diagnose this as a full head-unit (radio) replacement, which is expensive.
Common Symptoms
12-inch screen completely black or won't power on
Vertical lines across the display
Frozen or artifacted image
Audio still works via steering-wheel buttons but screen is dead
Screen blank only on certain menus (e.g., media)
How to Fix
First try a Uconnect software update and a hard reset (press and hold the volume/tuner controls; or a documented fuse-pull reset letting the unit sit so internal capacitors discharge). If the panel shows vertical lines or stays black after software steps, the display/head-unit assembly is replaced. Replacement units must be programmed; check for any active warranty/extended-coverage or software TSB before paying for a full radio.

On the 2003-2009 RAM 1500, the 2003-2009 Ram instrument clusters are known to fail from cold solder joints and cheap internal stepper motors that degrade under heat and vibration. Owners see erratic or stuck speedometer/tachometer, dead or wildly wrong fuel and temperature gauges, a dim or dead gear-position/odometer display, and fading backlighting. It is a top high-mileage electrical complaint.
Common Symptoms
Speedometer/tachometer erratic, stuck, or dead
Fuel or temperature gauge reads wrong
Dim or dead odometer/gear-indicator display
Backlighting flickers or goes out
Multiple gauges drop out together
How to Fix
Run the self-test (hold the trip/odometer button while turning key to RUN — gauges should sweep). Fix is a cluster rebuild: re-solder the board and replace the X27 stepper motors and backlight LEDs (specialist shops like Circuit Board Medics / Auto Tech Rescue rebuild the original for ~$150-$350). Avoid used clusters, which use the same failure-prone parts and need odometer/VIN reprogramming.

On the 1998-2010 RAM 1500, rams with the Sentry Key Immobilizer Module (SKIM/WCM) can lock out the fuel injectors if the module fails to read a valid transponder key. The engine cranks, fires for ~2 seconds, then dies, and the security/theft light stays on or blinks. Causes include a failing SKIM/WCM, a damaged antenna ring around the ignition lock, a worn transponder chip in the key, or wiring/connector corrosion.
Common Symptoms

No-start with a worn or non-transponder key
How to Fix
Read the security light while cranking (blinking = SKIM lockout). Diagnose with a scan tool that can access SKIM (basic code readers can't). Fix per cause: reprogram/relearn keys, replace the antenna ring, or replace and re-flash the SKIM/WCM (dealer or locksmith with the PIN). Verify battery/ground first. Typical $100-$400 depending on module vs. key relearn.

On the 2019-2024 RAM 1500, the eTorque mild-hybrid system's Belt Starter Generator (BSG/MGU), its tensioner/dampener, and the 48V battery pack are failure-prone. Owners report MGU bearing whine, a slipping belt after the tensioner loses tension (which trips the hybrid controller and disables assist), 48V battery faults, and a failing 48V-to-12V converter that leaves the 12V battery undercharged (reads below ~12.2V before crank). Symptoms include rough auto stop/start, warning lights, and loss of hybrid torque assist. Field failures were common enough that Stellantis is dropping eTorque from most 2027 HEMI builds.
Common Symptoms
Whine from front of engine
Rough or disabled auto stop/start
Hybrid/48V warning light
Loss of low-end torque assist
Repeated 12V battery drain/undercharge
Stall risk
How to Fix
Scan the hybrid/48V system for BSG and battery-pack fault codes and check 12V rest voltage and converter output. Replace the BSG/motor-generator unit and its dedicated belt/tensioner if bearing noise or slip is confirmed; replace the 48V battery pack if it throws cell faults or won't hold charge. Verify the 48V-to-12V DC converter is maintaining the 12V battery. Software updates address some stop/start and charging complaints. Work is high-voltage-rated and typically dealer-level.

On the 2025-2026 RAM 1500 3.0L Hurricane twin-turbo I6, a large number of 2025 RAM 1500 owners (especially Hurricane-equipped trucks) report repeated dead 12V batteries from a parasitic draw where body/comfort modules and proximity sensors fail to enter sleep mode after shutdown. Owners describe waking to a no-start, low system voltage, infotainment freezes, and wireless-charge pads that stay warm. One Texas owner documented an '11.7V death spiral' at under 4,000 miles, with dealers initially finding 'no fault.' Stellantis addresses it with a body-control-module software reflash TSB to force the affected modules to sleep. This is distinct from the older TIPM failure already covered — it is a 5th-gen DT software/electrical-architecture issue on the newest trucks.
Common Symptoms
Dead battery / no-start
Low system voltage warning
Infotainment freeze or reboot
Wireless charging pad overheating
Repeated battery replacement
How to Fix
Have the dealer apply the BCM/electrical-system software update that corrects the modules-won't-sleep condition (reported under a 2025 service bulletin). In the interim, a battery tender prevents dead-battery no-starts. If a dealer reports 'no fault found,' request the parasitic-draw software reflash specifically and have the 12V battery state-of-health load-tested, as repeated deep discharges can prematurely ruin the battery.

On the 2023-2024 RAM 1500, stellantis recalled approximately 129,000-164,000 2023-2024 RAM 1500 (DT) trucks because an interference condition in the steering column control module (SCCM) turn-signal lever mechanism can prevent the turn signal from canceling automatically after completing a turn. A turn signal that stays on misleads other drivers about the truck's intended direction, increasing crash risk. NHTSA campaign 24V729000 (manufacturer campaign A1B, Oct 2024). This 5th-gen electrical/safety issue is separate from anything currently in our list.
Common Symptoms
Turn signal does not cancel after turning
Turn signal stays on
Steering column / turn-signal lever fault
How to Fix
Safety recall — dealers inspect the steering column control module and replace it free of charge if the interference condition is present (NHTSA 24V729000). Owners noticing the turn signal failing to self-cancel after turns should verify their VIN at nhtsa.gov/recalls and schedule the free SCCM inspection/replacement.

On the 2019-2024 RAM 1500, the center-stack Uconnect infotainment touchscreen (8.4-inch and 12-inch units) randomly goes blank, freezes on the boot logo, reboots on its own while driving, or exhibits 'ghost touching' where it registers phantom presses. Because Uconnect also controls the HVAC temperature, backup camera, radio, phone/Bluetooth, and navigation on these trucks, a locked or dead screen can leave the driver unable to adjust climate or view the reversing camera. The root cause is generally a software/firmware fault in the head unit or telematics box (a Feb 2018 OTA update notably caused thousands of units to reboot roughly every 45 seconds), occasionally aggravated by a half-installed update or a loose/corroded harness connection. This is the center infotainment display and is distinct from the digital gauge/instrument cluster blank-out recall.
Common Symptoms
Center touchscreen goes blank or black at random
Screen freezes/stuck on Uconnect or RAM logo at startup
System reboots itself while driving and loses presets
Touchscreen unresponsive to inputs or registers phantom 'ghost' touches
Loss of backup camera, HVAC control, radio, or navigation display
How to Fix
Owners can attempt a two-button soft reset (press and hold the volume and tuner knobs together for ~10-15 seconds) or a deep-cycle reset (disconnect the 12V battery for 30+ minutes to fully drain the head-unit/telematics capacitors). The lasting fix is a dealer Uconnect software/firmware update; if the update does not resolve it, the radio/head unit or telematics control module is replaced. Some updates are available over-the-air or via USB flash.

On the 2019-2024 RAM 1500, the rear/backup camera intermittently drops out, showing a black screen or a blue 'Camera System Unavailable' message in reverse. The most common root cause is the camera wiring harness that routes through the tailgate hinge/pivot: repeated tailgate cycling flexes and eventually chafes or partially breaks the wires, giving an intermittent signal. Loose camera connectors and Uconnect software glitches are secondary causes. It is a frequent 5th-gen (DT) complaint distinct from the full touchscreen blank-out.
Common Symptoms
Black screen in reverse
Blue 'Camera System Unavailable' message
Camera cuts in and out
Image returns after cycling tailgate/ignition
Guidelines show but no picture
How to Fix
Inspect and flex-test the camera harness at the tailgate hinge for chafed/broken conductors and repair or replace the harness section; reseat the camera connector. If wiring is good, perform a Uconnect soft reset (hold phone + voice-recognition buttons ~30s) and apply the latest infotainment software reflash. Replace the camera module if the image is still absent with good wiring and software.

On the 2019-2023 RAM 1500, 5th-gen (DT) RAM 1500 trucks with the Uconnect 8.4 (and 12-inch) systems are widely reported to randomly reboot, freeze on the RAM logo, lose audio (sound cutting out every couple of seconds), and show backup-camera faults such as a blue screen, blank image, a large yellow square, or significant camera delay. Failures cluster in temperature extremes (below ~15F or above ~90F) and can occur at startup or after the system warms up. Some early trucks also had screen de-lamination/ghost-imaging hardware defects requiring radio replacement. A software update (TSB 08-003-19) was issued to address display freezing/glitches.
Common Symptoms
Screen randomly reboots or freezes on the RAM logo
Audio cuts out intermittently every couple of seconds
Backup camera shows blue/blank screen, yellow square, or long delay
Worse behavior in very cold or very hot weather
Screen de-lamination or ghost/burn-in images (early trucks)
How to Fix
Perform a Uconnect soft reset (key to RUN, then hold the volume knob and tuner knob together ~10-20 seconds) to clear a frozen screen. Have the dealer install the latest Uconnect software (per TSB 08-003-19) which addresses many freeze/reboot/camera cases. Persistent hardware faults (de-lamination, ghosting, dead camera image) require radio or camera replacement, ideally under powertrain/electrical warranty.

On the 1994-2001 RAM 1500, the electronically-controlled 42RE/46RE automatics regulate shift points with a PWM governor pressure solenoid plus a governor pressure sensor/transducer in the valve body. These parts get contaminated by transmission varnish and wear out. When the sensor feedback no longer matches the commanded pressure, the PCM sets a code and drops the transmission into 'limp' mode — no overdrive, 2nd/3rd-gear start, harsh or no shifts. Extremely common on high-mileage 2nd-gen Rams.
Common Symptoms
Transmission stuck in limp mode (2nd/3rd gear only)
No overdrive / no lockup
Wrong-gear starts
Harsh or delayed shifts
Speedometer-related shift errors
How to Fix
Drop the pan and replace the governor pressure solenoid (Mopar 4617210) and the governor pressure sensor/transducer (56028196AD, supersession of 56041403AA); available together as an aftermarket kit (e.g. Hercoo/TransGo).

On the 2013-2023 RAM 1500, the Ram 1500's transmission thermal-management/oil-cooler unit is the only place where engine coolant and automatic transmission fluid pass close together. When this cooler ruptures internally, coolant and ATF cross-contaminate, producing a pink 'strawberry milkshake' in both the cooling system and the transmission. This is a serious failure: contaminated ATF degrades clutches and seals inside the ZF 8-speed and can destroy the transmission if driven on, while loss of coolant risks overheating. Owners report this occurring in the 70k-mile range and across multiple model years. It is distinct from the previously covered torque-converter shudder/harsh-shift issues because the root cause is a cooling/cross-contamination failure, not a hydraulic/valve-body or converter problem.
Common Symptoms
Pink/milky 'milkshake' in coolant reservoir
Milky or contaminated transmission fluid
Low coolant with no external leak
Overheating
Harsh shifting or slipping after contamination
Sweet coolant smell
How to Fix
Stop driving immediately if a milkshake mixture is found. Replace the failed transmission oil cooler/thermal unit (verified Mopar PN 68322494AD for 2019-2026), then completely flush the cooling system and perform repeated transmission fluid-and-filter changes (or a full flush) to purge coolant from the transmission. If clutch material is already contaminated, a transmission rebuild or replacement may be required. Verify with a road test and fluid inspection afterward.

On the 2013-2023 RAM 1500, the ZF 8HP 8-speed automatic transmission can experience harsh shifting, hesitation, and jerky behavior. Some units have failed prematurely. Early model years (2013-2016) seem most affected. Multiple TSBs have been issued for software updates.
Common Symptoms
Harsh or delayed shifts
Transmission slipping
Jerky acceleration
Hesitation when accelerating
Check engine light with trans codes
How to Fix
First step: Get latest transmission software update from dealer (often free). Change transmission fluid and filter every 60,000 miles using ZF Lifeguard 8 fluid only. If problems persist, valve body replacement may be needed ($1,500-2,500). Full transmission replacement runs $4,000-6,500.

On the 2019-2025 RAM 1500, the 2019+ RAM 1500 uses the ZF 8HP75 8-speed automatic transmission which exhibits harsh shifting, delayed engagement, hesitation between gears, and rough downshifts. While the transmission itself is mechanically robust, the calibration and TCM (Transmission Control Module) programming have been problematic since launch. Stellantis has released multiple software updates via TSBs to address shift quality. TSB 21-018-22 REV.A addresses rough 1-2 upshift and 2-1 downshift. Some trucks require valve body replacement if software updates do not resolve the issue.
Common Symptoms
Harsh or jerky 1-2 upshift
Rough 2-1 downshift when stopping
Hesitation or delay when accelerating from stop
Transmission hunting between gears on hills
Clunking noise when shifting into Drive or Reverse
Delayed engagement when cold
How to Fix
First step: Visit dealer for the latest TCM software update (free under warranty). Reference TSB 21-018-22 REV.A for shift quality improvements. Perform a transmission adaptation reset after the update (dealer procedure). If software updates do not resolve the issue, valve body replacement may be needed ($800-1,500). Ensure transmission fluid is at proper level with correct Mopar ZF 8/9 speed ATF (68218925AB). Some owners report improvements after a complete fluid and filter change ($250-400).

On the 2013-2024 RAM 1500, the 8-speed (ZF 8HP70 / TorqueFlite) develops a torque-converter clutch shudder felt as a vibration/judder around 30-50 mph light throttle, along with harsh downshifts, drive-engagement slam, and occasional limp mode (stuck in one gear with CEL). Root causes are degraded/aged transmission fluid and worn torque-converter clutch material, sometimes with valve-body or solenoid issues. Ram markets the trans as 'sealed/lifetime fill,' but ZF recommends fluid service every ~40-60k miles, and skipping it drives most of these complaints.
Start with a proper fluid-and-filter service using the correct ZF 8HP fluid (many shudders clear up with fresh fluid) and apply the latest transmission software/TCM updates. If shudder persists, inspect/replace the torque converter; harsh-shift or limp events may require valve-body or solenoid repair. Adopt a 40-60k-mile fluid interval rather than the 'lifetime' claim to prevent recurrence.

On the 2013-2023 RAM 1500, rAM 1500s with the ZF-based 8-speed automatic (TorqueFlite 845RE / 850RE, 8HP70/8HP75) commonly develop torque-converter clutch shudder. It feels like a slight-to-heavy vibration or 'driving over rumble strips' at part throttle and light acceleration, typically 15-50 mph as the converter approaches lock-up. Owners frequently report it around the 70,000-80,000 mile range, often tied to degraded fluid friction-modifier and/or worn/glazed torque-converter clutch material. Severe cases drop into limp mode (locked in 3rd gear with a CEL). Harsh 1-2/2-3 upshifts are also reported and are often resolved by a TCM software reflash.
Vibration/shudder at light throttle, ~15-50 mph, near converter lock-up
Harsh or clunky 1-2 and 2-3 upshifts
Burnt-smelling or dark transmission fluid
Limp mode (stuck in 3rd gear) with check engine light
How to Fix
First request all available TCM/transmission software updates (multiple TSBs/reflashes exist). A full fluid-and-filter service with the correct ZF spec fluid resolves a large share of early shudder cases. Persistent shudder after fluid/software typically requires torque-converter replacement or rebuild. Stellantis specifies long fluid intervals, but many owners service the fluid by ~60k miles preventively.

On the 2019-2025 RAM 1500, the 2019+ RAM 1500 equipped with the optional four-corner air suspension system experiences compressor failures, air spring leaks, height sensor malfunctions, and control module issues. The truck may sag on one corner, fail to raise/lower, or display "Service Air Suspension System" warnings. The air compressor (Arnott P-3246) works constantly trying to compensate for leaks, eventually burning out. Cold weather accelerates air spring rubber deterioration. TSB 02-003-21 addresses air suspension height calibration issues. Individual air spring replacement costs $300-600 per corner, compressor replacement is $800-1,500, and a full system overhaul can exceed $3,000.
Common Symptoms
Vehicle sagging on one or more corners
Service Air Suspension System warning
Air compressor running constantly
Truck not raising to proper ride height
Loud compressor noise under vehicle
Uneven ride height side to side
Suspension feels bouncy or unstable
How to Fix
Diagnose with wiTECH to read air suspension fault codes and check height sensor readings. Leak test each air spring with soapy water at all seams and fittings. Check TSB 02-003-21 for height calibration procedure. Replace leaking air springs ($300-600 each, OEM Mopar 68364461AA for rear). If compressor is burned out, replace with OEM or Arnott P-3246 ($800-1,500). Some owners convert to traditional coil springs using a conversion kit ($800-1,200 for all four corners) to eliminate the air suspension entirely.

On the 2013-2024 RAM 1500, trucks optioned with the 4-corner air suspension commonly develop compressor strain and failure, air-line leaks, failed air dryer letting moisture in, and ride-height sensor faults. Symptoms include the compressor running excessively, the truck sitting low or refusing to change height, a 'Service Air Suspension' message, and cold-weather collapse when moisture freezes in the lines. Moisture contamination and small leaks that overwork the compressor are the root causes; failures are heavily documented for 2013-2020 (4th-gen) and continue on 5th-gen DT.
Common Symptoms
Truck sits low or uneven
Won't raise/lower or change ride height
Compressor runs constantly or is noisy
Service Air Suspension warning
Collapse in cold weather
Slow height response
How to Fix
Scan for suspension/ride-height fault codes and perform a leak-down/soap test on bags, lines, and fittings. Replace the compressor assembly (with integrated dryer) once it has overheated or fails to build pressure, repair or replace leaking air struts/bags and height sensors, and purge moisture. Rebuild kits and upgraded aftermarket compressors/dryers are common. Some owners convert to coil springs to eliminate the system. Keeping the dryer functional prevents cascading damage.

On the 2009-2018 RAM 1500, 4th-gen Ram 1500 front wheel bearing/hub assemblies wear out relatively early (some as low as ~50k miles), producing a humming or growling noise that rises with speed and changes with steering load. Because the wheel-speed sensor is integrated into the hub, a failing bearing frequently also sets an ABS/traction fault and light. It is one of the most common front-end noise complaints on these trucks.
Common Symptoms
Humming/growling that grows with speed
Noise changes when turning left/right
ABS or traction control light
Wheel play/looseness
Vibration through the floor
How to Fix
Confirm by road test (noise increases with speed, shifts when loading the bearing on turns) and check for play. Replace the affected front wheel bearing/hub assembly (unit-bearing with integrated ABS sensor); replace in pairs if both show wear. Torque the axle nut to spec. Some owners periodically grease through the ABS-sensor hole to extend life, but replacement is the fix once noise/ABS fault appears.

On the 2013-2023 RAM 1500, rAM 1500s equipped with the optional 4-corner air suspension (common on Laramie, Longhorn, Limited, Rebel) suffer recurring failures. The most common is air-bag micro-leaks (usually a rear bag) that make the compressor run continuously to keep up; the overworked compressor draws in humid air, ingests moisture that freezes in the air lines/dryer in winter, and the system collapses with a 'Service Air Suspension' message. Compressors then fail outright. Owners also report ride-height sensor faults; a software bug can falsely flag height sensors as 'stuck' (addressed by TSB 08-152-24). There have been class-action complaints over air-suspension reliability on roughly 2013-2018 trucks.
Common Symptoms
'Service Air Suspension' / 'Service Air Suspension Immediately' message
Truck sagging or sitting on the bump stops (one or more corners)
Compressor running constantly or audibly straining
Suspension collapse or won't air up in cold weather
Stuck at one ride height; height won't change
How to Fix
Diagnose for air-bag leaks first (soapy-water test on bags/fittings) before condemning the compressor, since a leaking bag is the usual root cause of compressor burnout. Replace leaking air spring(s), then the compressor/dryer assembly if it has failed. Apply the latest ride-height software/TSB (08-152-24) for false 'stuck sensor' faults. Some owners convert to a conventional coil-spring kit to eliminate the system. Dealer compressor replacement is often ~$2,500-$3,300; DIY parts can be far less.

On the 2014-2021 RAM 1500, the ABS/Electronic Brake Control Module (EBCM) on Ram 1500 trucks suffers internal electronic failures separate from the software-related ESC recalls. Owners report the ABS, brake, traction-control and related warning lights coming on together with stored codes such as C2200 (internal electronic failure), U0121 (lost communication with ABS module) and C2116 (pump motor fault / pump supply low voltage). C2116 in particular is a strong indicator the ABS pump/module itself has failed. The base brakes still function but ABS, stability and traction control are disabled, and the module must be VIN-programmed when replaced.
Common Symptoms
ABS, brake, and traction/stability lights illuminated together
Scan and confirm the module codes. For C2116/C2200 internal faults, the EBCM/ABS module is replaced (or sent for bench repair) and then programmed to the truck's VIN. Always check first whether the truck is covered by an active ABS-related recall or software TSB, which may fix the symptom for free. Verify proper brake-pedal feel and warning-light clearance after repair.

On the 2025-2026 RAM 1500, stellantis recalled 456,287 vehicles, of which roughly 312,000 are 2025-2026 RAM 1500 pickups, because a defective trailer brake and towing control module can cause the trailer's turn signals to fail to flash, the trailer brake lamps to not illuminate under braking, and in some cases the trailer's electric brakes to not function at all. NHTSA (campaign 26V059000, Feb 2026) estimates 100% of the recalled trucks contain the defect. Non-functional trailer brakes increase stopping distance and the loss of trailer lighting creates a rear-end-collision hazard. This is a brand-new-generation towing-safety issue affecting the newest trucks well outside prior coverage.
Common Symptoms
Trailer brakes not engaging
Trailer brake lights not illuminating
Trailer turn signals not flashing
Increased stopping distance while towing
How to Fix
Safety recall — the dealer replaces the trailer tow module with an updated design at no cost (NHTSA campaign 26V059000). Until the remedy is performed, RAM and safety advisories recommend avoiding towing trailers that rely on the integrated trailer brake controller. Owners should verify their VIN at nhtsa.gov/recalls and schedule the free module replacement.

On the 2013-2022 RAM 1500, two separate, widely-publicized recalls cover Ram 1500 tailgates that can pop open while driving. On power-locking-tailgate trucks (NHTSA 19V-347, expanding the earlier 18V-486), the tailgate actuator limiter tab can fracture and let the tailgate unlatch and drop while moving. A later, much larger campaign (NHTSA 22V-904, ~1.23 million U.S. trucks, 2019-2022 model years) covers tailgate strikers that can be misaligned to the box latch so the tailgate is not fully latched. In either case the gate can open at speed, dumping unsecured cargo and creating a road hazard.
Common Symptoms
Tailgate pops open or drops while driving
Tailgate will not stay latched / latches loosely
Cargo falling out of the bed on the road
Misaligned tailgate-to-bed gap
How to Fix
These are free safety-recall repairs. For 19V-347/18V-486 (power tailgate), dealers install a stop block to prevent the gate opening if the limiter tab fractures. For 22V-904 (striker), dealers inspect tailgate striker-to-latch alignment and adjust as needed. Owners should run their VIN at nhtsa.gov/recalls or mopar.com to confirm which campaign applies, then schedule the free remedy. Until repaired, avoid hauling unsecured loads and verify the tailgate is fully latched.

A damaged encoder ring causes loss of the wheel-speed signal, which can deactivate Electronic Stability Control (ESC) — a key system that prevents skidding and loss of control. NHTSA campaign 24V794000 (Nov 2024). This is a 5th-gen-specific safety defect, distinct from the general front-hub-bearing wear noise issues; here the ring damage silently disables ESC.

On the 2014-2019 RAM 1500 3.0L EcoDiesel V6 (VM Motori A630), on 2014-2019 RAM 1500 and 1500 Classic trucks with the 3.0L EcoDiesel V6, the exhaust gas recirculation (EGR) cooler is prone to thermal fatigue. Repeated heating/cooling cycles cause hairline internal cracks that let pre-heated, vaporized engine coolant enter the EGR/intake path. That coolant vapor can combust inside the plastic intake manifold, melting the manifold and igniting an under-hood fire. FCA US LLC issued NHTSA recall 19V-757 (manufacturer campaign VB1) in October 2019 covering roughly 100,000 trucks. Owners have widely reported that even the recall replacement EGR coolers later fail again, and that collateral damage (melted intake manifold, contaminated cooling system) is sometimes not fully covered.
Common Symptoms
Unexplained engine coolant loss with no visible external leak
White or sweet-smelling exhaust smoke
Burning/melting plastic smell from engine bay
Loss of power or rough running
Smoke or fire from under the hood
How to Fix
Have the recall (19V-757 / VB1) performed at a Stellantis dealer free of charge: the EGR cooler is replaced and the intake manifold inspected/replaced as needed. If symptoms recur (coolant loss, white exhaust smoke, burning smell, loss of power), return immediately and document for the campaign. Some owners proactively replace the EGR cooler with a revised/updated unit and monitor coolant level. Park outside and away from structures if a fire-risk condition is suspected.

On the 2009-2024 RAM 1500 5.7L HEMI V8, the 5.7L HEMI's factory exhaust manifold bolts/studs snap from repeated heat cycling, and the cast manifolds can warp or crack. The classic tell is a sharp tapping/ticking on cold start that quiets as the engine warms and the manifold expands to partially reseal the leak. Nearly every high-mileage HEMI develops this, often by ~100k miles. It is frequently confused with lifter tick, but the exhaust leak is loudest right after startup and diminishes as it warms.
Common Symptoms
Sharp tick/tap on cold start that fades when warm
Exhaust smell
Soot at manifold flange
Louder exhaust note
Occasional CEL from O2 readings
How to Fix
Confirm with a visual/soot inspection of the manifold-to-head flange and a cold-start listen. Extract broken bolts (often snapped flush in the head), replace the manifold gaskets, and reinstall using upgraded stainless ARP studs or a heavy-duty bolt/spring kit to prevent recurrence. Replace cracked/warped manifolds as needed. Left alone it worsens and can damage O2 sensors and reduce economy.

On the 2013-2022 RAM 1500 5.7L HEMI V8, the 5.7L HEMI uses cast-iron exhaust manifolds bolted to aluminum cylinder heads. The dissimilar thermal expansion rates repeatedly stress the manifold-to-head fasteners, and the rearmost bolts (commonly cylinders 7 and 8) shear off. This produces a sharp 'tick' or exhaust ticking that is loudest on cold start and quiets as the engine warms and the gap closes. It is frequently mistaken for the internal 'HEMI tick' (lifter) but is actually an exhaust leak. Owners report it commonly appearing by ~100k miles, and it is widespread across the 4th-gen (2013-2018) and 5th-gen (2019+) trucks.
Common Symptoms
Sharp ticking that is loudest on cold start, fades as engine warms
Exhaust smell in the engine bay or near the wheel well
Black soot marks near the manifold flange/gasket
Tick that does NOT track with MDS engagement (distinguishes from lifter tick)
How to Fix
Inspect the manifold flange for soot/black marks and listen with the engine cold. Repair by extracting the broken bolts/studs and replacing the manifold gaskets; many shops and owners upgrade to ARP studs (~$80) to prevent recurrence, and some replace warped manifolds. Typical professional repair runs roughly $1,000-$1,500 depending on how many bolts are seized/broken and whether extraction is difficult.

On the 2014-2022 RAM 1500 3.0L EcoDiesel, the 3.0L EcoDiesel engine can experience fuel pump failures and stalling issues. The high-pressure fuel pump (CP4) is sensitive to fuel contamination and can fail catastrophically, sending metal debris throughout the fuel system. Water in fuel accelerates failure.
Always use high-quality diesel fuel from reputable stations. Install a aftermarket fuel filter/water separator like the FASS system ($800-1,200) for added protection. If CP4 fails, expect $8,000-12,000 for full fuel system replacement. Add diesel fuel additive with lubricity enhancer every fill-up.
Owner tips & cautions
TipDIY repairs can save significantly - dealer charges $800-1,200 but DIY costs are typically 50-70% less
WarningThis is a high-severity issue - ignoring it can lead to costly repairs or safety concerns. Address it promptly.
TipConsider OEM parts for critical components like sensors and electrical parts - aftermarket can be unreliable

On the 1994-2010 RAM 1500, the in-tank fuel level sending unit (float arm and variable-resistor card, part of the fuel pump module) wears out and gives false readings — commonly reading full then dropping to empty, sticking, or bouncing. On OBD-II trucks it sets P0463/P0462. It is one of the most-searched Ram gauge complaints and is separate from the instrument-cluster fault.
Common Symptoms
Gauge reads full then suddenly drops to empty
Gauge stuck on empty or full
Erratic/bouncing needle
Low-fuel light behaves incorrectly
How to Fix
Confirm the sender resistance sweep before replacing the cluster. Repair requires dropping the tank (or removing the bed) and replacing the fuel level sending unit — often done as a complete fuel pump/sender module for reliability. Avoid the cheapest unbranded senders, which frequently read wrong out of the box; use a quality module (Delphi/Spectra/Mopar). Parts $60-$250, with labor $150-$500.

On the 2015-2023 RAM 1500, the DT-generation Ram 1500 uses a belt-driven electric power steering (EPS) system with the assist motor and control module integrated into the rack-and-pinion. When the EPS module shorts out or the motor fails, the driver loses power assist — sometimes momentarily at startup, sometimes permanently — and the steering becomes very heavy with an 'EPS' or 'Service Power Steering' warning. Because the motor/module are not serviceable separately, a failure requires replacing the entire rack assembly. Earlier 2015-2016 trucks had a related FCA-identified circuit-board contamination defect in the EPS unit.
Common Symptoms
Sudden heavy/manual steering with loss of power assist
EPS or 'Service Power Steering' warning light
Momentary loss of assist at startup
Clunk or whine from the steering rack
Steering wander or dead spot on-center
How to Fix
Confirm with a scan tool (EPS control module fault codes) and check the 48V/12V supply and EPS connector before condemning the rack. The fix for a failed unit is replacement of the complete electric rack-and-pinion assembly and recalibration; owners report total repair bills of roughly $3,000-$4,000, often not covered once the basic/powertrain warranty expires. Keep the steering software flashed to the latest level, as some startup-only assist dropouts are resolved by an EPS software update rather than hardware.

On the 2019-2022 RAM 1500, a widely reported 5th-gen (DT) Ram 1500 complaint is a grinding, rubbing, or shuddering noise and vibration felt through the steering wheel when turning right (and sometimes left) at low speeds, typically around 8-12 mph. Inspection usually finds nothing physically contacting; the noise originates in the electric power steering assist and is felt as a 'rubbing' in the wheel. It is distinct from EPS hardware failure — the truck still steers normally, it just makes the noise.
Common Symptoms
Grinding or rubbing noise when turning right at ~8-12 mph
Vibration felt in the steering wheel during slow turns
Noise with no visible component contact
Shudder when turning from a stop
How to Fix
Ram addressed this with an EPS software update — TSB 08-137-21 (and earlier revisions) reflashes the electronic power steering module to the latest calibration, which eliminates or greatly reduces the low-speed grind for most trucks. Some dealers also apply a steering-system friction modifier. The repair is a free software flash under warranty; out of warranty it is typically a low-cost dealer reprogram. Owners should insist the truck be road-tested at the exact speed where the noise occurs since it can be hard to reproduce on a lift.

On the 2019-2024 RAM 1500, the 2019-2024 RAM 1500 (5th generation, DT) has a well-documented rear window water leak that allows water to enter the cab during rain or car washes. Water drips from the top of the rear window area, soaking the rear seat and rear floor. The issue is caused by inadequate sealing between the rear window and the cab, particularly at the upper corners. TSB 23-005-19 REV.B addresses this with an updated seal and butyl tape application procedure. If untreated, the water intrusion can cause mold, electrical issues with rear seat wiring, and corrosion of the cab structure.
Common Symptoms
Water dripping from top of rear window inside cab
Wet rear seat or rear floor after rain
Musty or mold smell inside cab
Water stains on headliner near rear window
Visible water pooling behind rear seat
Corrosion or rust under rear seat area
How to Fix
Check TSB 23-005-19 REV.B for the official repair procedure. The fix involves removing the rear window, cleaning old sealant, applying new butyl tape (Mopar 05019293AB) and urethane sealant in a specific pattern, and reinstalling the window. Some dealers also apply additional sealant at the upper corners. DIY temporary fix: Apply clear silicone sealant along the top edge of the rear window exterior ($10-20). Proper dealer repair under warranty is recommended.

On the 1994-2008 RAM 1500, these Rams are widely known for rust-through at the rear wheel arches, lower quarter panels, cab corners, rocker panels, and the bed (inner bedside rusts out to the exterior on trucks through ~2006 due to poor drainage and moisture-trapping foam in the bed rails). It is severe and common enough that a large aftermarket of stamped repair panels exists specifically for these years.
Common Symptoms
Bubbling/rust-through at rear wheel arches
Holes in cab corners
Rocker panel corrosion
Bed sides rusting from the inside out
Perforation spreading from trapped debris/salt
How to Fix
Address early: treat surface rust, keep drains clear. For rust-through, cut out the affected metal and weld in reproduction panels — rear wheel-arch skins, cab-corner patches, rocker and bed patch panels (Raybuck, Mill Supply, Classic 2 Current). Prime, seal, and undercoat. DIY panels cost $30-$150 each; professional cut-and-weld with paint runs $500-$3,000+ depending on extent.

On the 2016-2022 RAM 1500, ram 1500 cabs leak water in through the roof-mounted third brake light, the rear cabin/sliding window, and the roof antenna base. Water tracks along a channel from the third brake light down the passenger A/C-pillar to under the seat, soaking the headliner and carpet and causing mildew and electrical shorts. On 2019-2020 trucks the encapsulated rear-window frame that bonds to the glass can crack. The problem is severe enough to be the subject of a class-action lawsuit covering 2016-2022 trucks; Chrysler issued a Feb 2021 TSB directing dealers to add a secondary seal at the third brake light.
Common Symptoms
Wet headliner after rain or car wash
Soaked passenger carpet/floor
Musty/mildew smell
Water dripping from A-pillar or dome light
Fogged interior glass
Electrical faults from moisture
How to Fix
Perform a targeted water test to identify the entry point (third brake light, rear window, or antenna). Per the TSB, remove the third brake light and add/replace the secondary foam seal and reseal with butyl. Reseal or replace a cracked rear-window encapsulation and reseal the shark-fin antenna base. Dry and treat the headliner/carpet to prevent mold, and check for corroded connectors under the passenger seat.

On the 2019-2023 RAM 1500, 5th-gen DT Ram 1500 tailgates use a solenoid latch motor on each side. Owners report the tailgate intermittently refusing to open from the handle, key fob, or in-cab release even though the actuator can be heard clicking; many find it only opens if they push inward on the gate while pulling the release. Root causes documented by technicians include factory passenger-side latch/striker misalignment, dust accumulation from hauling dirt jamming the solenoid latches, and lack of latch lubrication on the DT design. FCA STAR Case S1808000156 addresses tailgates that fail to release or drop on request.
Common Symptoms
Tailgate won't open from handle, fob, or in-cab button
Actuator clicks but gate stays latched
Opens only when pushing inward on the gate
One side latches/releases but the other doesn't
Latch sticks in cold or dusty conditions
How to Fix
Dealers inspect striker-to-latch alignment and adjust per the STAR case, lubricate the latches, and replace a failed solenoid latch assembly under warranty when needed. As an interim workaround, pulling the release while bumping the gate inward usually opens it; the latches can also be released manually through the access panel. Keep the latches clean and lubricated, especially after hauling dirt/debris.

On the 2019-2024 RAM 1500, trucks equipped with the dual-pane panoramic sunroof commonly develop wind noise from the front edge of the glass, a rattle or knock when the body flexes, and in some cases water intrusion into the cab. The front corners of the glass panel often do not seal tightly against the weatherstrip when closed, allowing air whistle and leaks; leaks are frequently traced to sunroof drain tubes that were not correctly routed/seated in the rear cab pillars at the factory (most reported on 2019 builds).
Common Symptoms
Wind whistle/roar from front of sunroof at highway speed
Rattle or knock from the roof when the truck flexes over bumps
Water dripping onto headliner, A-pillars, or floor
Front corners of glass not sealing flush when closed
How to Fix
For wind noise/rattle, the dealer realigns and adjusts the glass panel height and replaces or repositions the weatherstrip; if adjustment fails, the sunroof track/cassette is replaced under warranty. For leaks, clear and correctly re-route the front and rear drain tubes (a frequent factory mis-installation) and verify they exit at the rocker/pillar; clogged tubes should be flushed. DIY glass realignment is possible but warranty coverage makes a dealer visit the better path while in the 3yr/36k basic warranty.

On the 2011-2023 RAM 1500, 4WD-equipped Ram 1500 trucks use an electric shift motor (encoder/gear motor) bolted to the BorgWarner transfer case to move between 2WD, 4WD-Auto, 4-High and 4-Low. The motor's internal plastic gears wear or strip, and water/road-salt intrusion corrodes the connector and motor windings, so the system fails to complete a shift. The dash shows 'Service 4WD,' the mode indicator blinks without engaging, and grinding or clicking can be heard from under the truck. A large share of Ram 4WD-engagement complaints trace to the shift motor rather than internal transfer-case damage, so it is usually a relatively affordable fix if caught early. FCA TSB 08-094-20 provides a Drivetrain Control Module (DTCM) software update for 2016-2020 trucks with this symptom.
Common Symptoms
'Service 4WD' warning message
4WD will not engage or disengage
Mode indicator blinks but never locks in
Grinding or clicking under the truck when shifting modes
Stuck in 2WD or stuck in 4WD
How to Fix
Scan for transfer-case/DTCM codes and check the connector for corrosion first. Apply the DTCM software update (TSB 08-094-20) if applicable. If the motor's gears are stripped or windings are open, replace the transfer case shift/gear motor (verified Mopar PN 68450803AA for 2019-2025 DT; actuator 68369691AD) and reprogram if required. Keep the connector clean and protected from salt; for trucks used in snow/off-road, periodic inspection prevents being stranded in the wrong mode.

On the 2009-2023 RAM 1500, ram 1500 rear (and sometimes front) differential pinion seals weep gear oil at the pinion flange, leaving residue on the driveshaft yoke and a wet spot at the front of the diff. The leak itself is minor, but improper repair is the bigger problem: if the pinion nut is not torqued correctly (and a fresh crush spacer used), the pinion bearing preload is wrong and a whine develops weeks later — whine on acceleration points to the pinion gear, whine on deceleration/coast points to a worn pinion bearing. Owners report the leak around 60k-70k miles and follow-on whining after a dealer reseal.
Common Symptoms
Gear oil residue on the pinion flange/driveshaft yoke
Wet front face of the rear differential
Whine that rises with speed on acceleration
Whine on coasting/deceleration
Low differential fluid level
How to Fix
Replace the pinion seal using a new crush spacer (collapsible) and torque the pinion nut to spec to set proper bearing preload; using thread-locking adhesive on the nut helps prevent re-leaks. If a whine is already present, the pinion bearing and ring-and-pinion may need inspection/replacement and a re-shim. Verify gear-oil level and use the correct spec fluid (with friction modifier for limited-slip).

On the 1994-2001 RAM 1500, second-gen 4WD Rams use a vacuum-operated Central Axle Disconnect (CAD) on the front axle to lock the right axle shaft when 4x4 is selected. The rubber/plastic vacuum lines become brittle and crack, the vacuum switch fails, or the CAD diaphragm/actuator ruptures — so the transfer case engages but the front axle never locks in and there's no front drive (or it won't disengage). A frequent cause of 'my 4x4 doesn't work.'
Common Symptoms
Transfer case shifts to 4x4 but no front-wheel drive
4WD won't engage or won't disengage
Grinding/no lock at the front axle
Vacuum leak / rough idle from cracked CAD lines
How to Fix
Diagnose vacuum before parts: with engine running, one line to the axle shift motor should read ~20 in-Hg and switch when the transfer case is shifted. Replace cracked vacuum lines and the vacuum switch first; replace the CAD actuator if the diaphragm is ruptured. A permanent fix is a cable-operated 4x4 Posi-Lok kit that eliminates the vacuum system. Parts $30-$200; typical repair $100-$400.

On the 2013-2022 RAM 1500, the front-mounted A/C condenser on 4th- and 5th-gen Ram 1500 trucks develops refrigerant leaks from corrosion and tiny pinholes, sometimes because units were not built to specification. Once refrigerant escapes, the system blows warm and the compressor can stop cooling or shut down to protect itself. FCA issued a warranty extension covering some condensers that were not manufactured to spec (this coverage specifically excludes rock/road-debris impact damage). Owners report oily residue on the condenser fins and progressively weaker A/C, especially in hot weather.
Common Symptoms
A/C blows warm or only cools intermittently
Gradual loss of cooling performance over a season
Oily refrigerant residue on condenser fins or under the front of the truck
Compressor cycling rapidly or not engaging
Needs frequent recharges
How to Fix
Have the system leak-tested (UV dye or electronic sniffer) to confirm the condenser as the source versus a hose, O-ring or compressor. If the truck qualifies for the manufacturing-defect warranty extension, the condenser may be replaced at no/low cost; otherwise replace the condenser (verified Mopar PN 68322495AB / 68312697AC for 2019-2024 DT), evacuate and recharge the system, and verify with a pressure/leak test. Add a condenser guard if impact damage is a concern.

On the 2009-2022 RAM 1500, the plastic-geared HVAC blend-door actuators behind the dash strip their gears over time, producing a repetitive clicking or knocking from behind the glove box or center dash and temperature control problems such as one side blowing hot while the other blows cold, or no heat/AC on one zone. A secondary, related cause on these trucks is the factory housing sealant 'melting' into a black sticky residue that makes the blend doors stick, plus heater-core sediment that restricts the driver-side fingers. It is a common, lower-cost comfort complaint but a frequent search/repair item.
Common Symptoms
Clicking/knocking noise from behind the dash or glove box
One side blows hot, the other cold (dual-zone)
No heat or no AC on one side
Temperature does not change when adjusting the dial
Airflow stuck on certain vents
How to Fix
Confirm with a scan tool / actuator calibration which actuator is failing (there are multiple behind the glove box and dash). Replace the failed blend-door actuator (verified Mopar PN 68396062AB for 2019-2022); if the door is stuck from melted sealant or the heater core is restricted, the HVAC housing must be serviced or the heater core replaced. Recalibrate the HVAC system after replacement.

On the 2011-2021 RAM 1500 5.7L HEMI V8, ram 1500 5.7L HEMI trucks commonly throw P0420 (Catalyst System Efficiency Below Threshold, Bank 1) and P0430 (Bank 2). On these engines the most frequent true cause is not a worn catalyst but an exhaust leak — a cracked exhaust manifold or broken manifold bolts (the same source as the cold-start tick) — which lets the downstream O2 sensor read incorrectly, or a failing downstream O2 sensor itself. The actual catalytic converter can also degrade with age/oil contamination. Because the converter is expensive, misdiagnosis leads owners to replace the cat unnecessarily before ruling out manifold leaks and O2 sensors.
Common Symptoms
Check engine light with P0420 and/or P0430
Cold-start ticking (exhaust manifold leak)
Slightly reduced fuel economy
Sulfur/rotten-egg exhaust smell
Failed emissions test
How to Fix
Before replacing the catalytic converter, inspect for exhaust manifold cracks/broken bolts and test the upstream and downstream O2 sensors; check for any PCM software update addressing catalyst-monitor sensitivity. Repair manifold leaks and replace a lazy downstream O2 sensor first. Only replace the catalytic converter once leaks and sensors are confirmed good. Address any underlying rich-running cause (MAF, fuel trim) so a new cat is not damaged.

On the 2013-2024 RAM 1500, a very common check-engine complaint is EVAP 'small leak' codes P0456/P0442 (and sometimes P0455). On 2013-2020 trucks the usual culprits are the Evaporative System Integrity Monitor (ESIM) pump on the charcoal canister or a failed purge valve; on 2019+ capless-filler trucks the capless fuel-filler seal or the purge valve is the frequent cause. It won't harm the drivetrain but fails emissions testing and is a high-frequency search among owners.
Common Symptoms
Check engine light
P0456/P0442 stored codes
No driveability change
Occasional faint fuel smell
Failed emissions/state inspection
How to Fix
Do not just clear the code — smoke-test the EVAP system to pinpoint the leak. Replace the ESIM (an inexpensive DIY on the canister) or the purge valve if it fails to hold vacuum, and inspect/replace the capless fuel-filler seal on 5th-gen trucks. Verify the gas cap/filler seals and check EVAP lines for cracks. Re-run the EVAP monitor to confirm the repair.

On the 2019-2024 RAM 1500, the 2019-2024 RAM 1500 dashboard develops cracks, warping, and deformation, particularly in hot climates. Cracks commonly appear near the defroster vents, along the passenger side airbag seam, and around the center console area. The issue is attributed to UV exposure and thermal cycling degrading the dashboard material. Vehicles parked outdoors in southern states (AZ, TX, NV, FL) are most affected. While primarily cosmetic, cracks near the passenger airbag seam could theoretically affect airbag deployment. Dashboard replacement costs $1,500-2,500+ at the dealer.
Common Symptoms
Visible cracks on dashboard surface
Dashboard warping or bubbling near defroster vents
Cracking along passenger airbag seam
Sticky or tacky dashboard surface in heat
Rattling sounds from warped dashboard panels
Gaps forming between dashboard sections
How to Fix
If under warranty (3yr/36k bumper-to-bumper), request dashboard replacement from dealer. Document the cracks with dated photos. For out-of-warranty vehicles, dashboard cover/mat ($40-80) prevents further UV damage and hides existing cracks. Full dashboard replacement is $1,500-2,500 at dealer. Some owners have successfully obtained goodwill coverage from RAM/Stellantis customer service for this issue. Use a windshield sun shade to prevent further UV damage.

On the 2019-2022 RAM 1500, owners of 5th-generation (2019+) RAM 1500 trucks with the dual-panel panoramic sunroof report water leaking into the cab — typically dripping from the middle seam where the two glass panels meet or onto the headliner — most commonly traced to drain tubes that were not correctly seated in the rear cab wall (concentrated in early 2019-2020 builds). A separate complaint is a persistent rattle/creak from the front passenger corner of the sunroof where the panels meet. Unaddressed leaks can wet the headliner and reach electrical connectors. This is an interior/water-intrusion issue separate from the rear-window leak already in our data.
Common Symptoms
Water dripping from sunroof seam
Wet headliner
Water on floor
Rattle or creak from sunroof
Wind noise from roof
How to Fix
Have the dealer or a body shop inspect and reseat/clear the sunroof drain tubes (front and rear) and confirm they route into the rear cab wall correctly; blocked or disconnected tubes are the most common leak cause. For rattles, the sunroof glass alignment/shims and seal can be adjusted. After any leak, dry the headliner and check nearby electrical connectors for corrosion. Many repairs are covered under the 3yr/36k basic warranty.

On the 2011-2023 RAM 1500, the mechanical, belt-driven water pump on the Ram 1500 is a long-standing weak point across Chrysler products. The shaft seal and bearing wear, and coolant begins seeping from the weep hole at the bottom of the pump. Failures are reported across a wide mileage range, from as low as ~33,000 miles on some 2022 trucks to well over 150,000 miles, and the issue has recurred for many model years. If ignored, a failing pump can lead to coolant loss and overheating, which on pre-2009 HEMIs is also a trigger for the dropped-valve-seat failure. A worn serpentine belt or tensioner can shorten pump life.
Common Symptoms
Coolant dripping from the weep hole at the front of the engine
Low coolant level / repeated top-offs
Coolant smell or puddle under the front of the truck
Whining or grinding from the pump bearing
Temperature gauge climbing
How to Fix
Replace the water pump (and inspect/replace the thermostat, gasket, belt and tensioner as needed) at the first sign of weep-hole seepage or bearing noise. Use a quality OEM/enhanced pump; the revised Mopar 'enhanced' water pump (verified PN 68346916AB; alt 68346915AA) addresses earlier seal weaknesses. Pressure-test the cooling system after replacement and refill with the correct OAT coolant.

On the 2017-2022 RAM 1500, owners of late-DS and 5th-gen (DT) Ram 1500 trucks report premature paint and clear-coat failure — peeling, flaking, and bubbling — most often starting on the color-matched bumpers but also seen on hoods, roofs, and other exposed panels, frequently within 2-3 years or under ~30k miles. Owners and paint specialists attribute it to thin factory paint/clear-coat film build (some trucks measured well below typical thickness) and a paint-formula change around 2017-2019. The result is delamination of the clear coat exposing primer and accelerating corrosion of the underlying surface.
Common Symptoms
Clear coat peeling or flaking off bumpers
Paint bubbling or blistering on hood/roof
Primer or bare surface showing through
Premature chipping/softness of paint at low mileage
How to Fix
There is no recall; remedy is a paint-warranty claim (Stellantis basic paint coverage is 3yr/36k) or goodwill repaint of the affected panel/bumper — get it documented early before it spreads. Out of warranty, the fix is professional sanding/refinishing of the affected panel; a single bumper or panel repaint typically runs $300-$900, more for a hood or roof. Owners should photograph and report peeling as soon as it appears to strengthen a warranty/goodwill case.
