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.
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.

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revised the rocker part several times to improve needle-bearing durability, so a repeat failure is common if an outdated rocker is installed.
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 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.
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 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.
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 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.
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 2018 RAM 1500, fCA US recalled certain 2018 RAM 1500 trucks under NHTSA campaign 18V524000. The powertrain control module fitted to these trucks may use a voltage regulator chip in its circuit board that is capable of failing in service. The result for the driver is a stall or a no-start. NHTSA records the component as electrical system, wiring, front underhood, and lists the consequence as an increased risk of a crash from a vehicle stall. The same campaign covers a broad set of Jeep, Dodge, Chrysler, Fiat and RAM models from the same period.
Common Symptoms
Truck stalls while driving
Engine will not start
How to Fix
Take the truck to a RAM dealer: the powertrain control module is replaced free of charge under Chrysler campaign U87. Owner letters went out beginning October 2, 2018. If you bought the truck used, do not assume the previous owner completed it — run the VIN through nhtsa.gov/recalls, and call Chrysler customer service at 1-800-853-1403 if you need help locating the repair.
On the 2014-2019 RAM 1500 3.0L EcoDiesel V6 (VM Motori A630), nHTSA 19V757 / FCA VB1 establishes this identity for affected 2014-2019 RAM 1500 and 1500 Classic trucks with the 3.0L EcoDiesel. The EGR cooler may crack, allowing pre-heated vaporized coolant into the EGR system; the mixture can combust in the intake manifold and increase fire risk. The campaign is VIN-specific and does not establish an owner-frequency total.
Common Symptoms
VIN checked for 19V757 / VB1
coolant loss and smoke or odor documented
EGR cooler and intake manifold inspected under campaign procedure
open recall and completed remedy confirmed
How to Fix
Check the VIN for 19V757 / VB1 and have the dealer replace the EGR cooler and inspect or replace the intake manifold as necessary, free of charge. If coolant loss, smoke, a burning odor or fire occurs, stop safely, shut down, exit and call emergency services when needed. Do not buy an EGR cooler or intake manifold from this page; campaign eligibility, completed remedy, current part number and VIN fitment must be established first.
On the 2009-2018 RAM 1500 5.7L HEMI V8, the 5.7L HEMI's exhaust manifold bolts, particularly the rearmost ones on each head, are a well-documented failure item. Repeated heat cycling stretches and eventually snaps them, and once a bolt lets go the manifold lifts off the head just enough to open a gap at that port. On the bank 2 (passenger-side) manifold the resulting leak is upstream of the bank 2 sensor 1 oxygen sensor, so the sensor is measuring a stream that has been diluted with outside air pulled in during the negative-pressure part of each exhaust pulse. The transitions the PCM is timing get smeared, the measured switch time runs past the calibrated limit, and P0153 is stored. The same defect is behind the notorious cold-start 'HEMI tick' - the leak whistles or ticks while the metal is cold and contracted, and quiets once thermal expansion closes the gap, which is why many owners hear the noise for a couple of minutes each morning and then dismiss it. A cracked manifold produces an identical picture. Because the leak also skews the fuel trims and can push a false lean condition downstream, P0153 on these trucks is often accompanied by P0171/P0174 lean codes or catalyst codes, and shops that skip the leak test end up selling a sensor - or worse, a catalytic converter - that does not fix the complaint. Chrysler has also issued a PCM software update (TSB 18-050-21) for trucks setting P0153 together with P0133, P0171, P0174 and P0300, so a reflash should be checked for before parts are bought. A related but separate version of this failure shows up on HEMI trucks fitted with aftermarket long-tube headers, where the relocated O2 bung sits farther from the port, sees cooler and slower-moving gas, and sets the same slow-response code on an otherwise healthy sensor.
Common Symptoms
Check engine light with P0153, sometimes with P0133, P0171/P0174 lean codes or catalyst codes
Cold-start ticking or hissing from the passenger-side exhaust manifold that fades as the engine warms
Exhaust smell noticeable at idle
Reduced fuel economy
Slight hesitation or uneven idle
P0153 returns after a new bank 2 sensor 1 is installed
How to Fix
Confirm the leak before buying parts. Listen at the passenger-side manifold flange on a cold start for a rhythmic tick or hiss that fades as the engine warms, then inspect each manifold bolt from underneath - a snapped bolt often leaves a visible gap, soot fanning out from the port, or a shiny witness mark where the flange has been moving. A smoke test of the exhaust or a propane test at the flange while watching short-term fuel trims will confirm it. The accepted repair is to remove the manifold, extract the broken bolt stubs from the cylinder head, and reassemble with new gaskets and an upgraded bolt or stud kit; many shops fit revised hardware or a stud-and-nut conversion so the joint can be serviced without drilling next time. If a bolt broke flush or below the deck surface it must be drilled and extracted with the head in place, which is the difference between a moderate bill and a large one. Replace the manifold outright if it is cracked rather than merely unbolted. Check for the applicable PCM software update (TSB 18-050-21 covers P0153 set with P0133, P0171, P0174 and P0300) at the same time, since a reflash is a known remedy for the oversensitive O2 monitor on this platform. Once the exhaust is sealed, verify the bank 2 sensor 1 signal on a scan tool at operating temperature; if it is still sluggish, fit a genuine Mopar or NTK sensor - owners report generic replacements re-setting slow-response codes even when the exhaust is sound. On trucks with aftermarket headers, the fix is usually a bung relocated closer to the collector, an O2 extender removed, header wrap to keep gas temperature up, or a calibration change to the slow-response monitor rather than another sensor.
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 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 2013-2023 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.

High Confidence2,876 owner reportsLast reported by owners Feb 2024Reviewed Feb 2026
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 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.

Timken HA590354 front wheel hub and bearing assembly
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 2014-2022 RAM 1500 3.0L EcoDiesel, nHTSA 22V406 / FCA Z46 covers affected 2014-2019 RAM 1500 trucks with the 3.0L diesel, while 22V767 / FCA Z96 covers affected 2020-2022 RAM 1500 trucks with that engine. High-pressure fuel-pump failure can introduce debris or cause fuel starvation and an unexpected loss of drive power. Together the campaigns support the indexed model-year span, but only VIN-selected vehicles are included and no owner-frequency count is established.
rail pressure and contamination evidence preserved
pump and downstream fuel-system scope established
How to Fix
Check the VIN for Z46 / 22V406 and Z96 / 22V767. Have the dealer replace the high-pressure fuel pump and inspect or replace additional fuel-system components as necessary, free of charge. If the engine stalls or loses power, use hazards, steer and brake to a safe location and arrange service. Do not buy a high-pressure pump, injector, rail or fuel-system kit from this page; campaign eligibility, contamination extent, completed remedy, current part number and VIN fitment must be established first.
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 2013-2022 RAM 1500, three NHTSA campaigns establish two VIN-bounded mechanisms under this frozen identity. NHTSA 18V486 / FCA U74 and 19V347 / FCA V44 cover specified 2013-2018 RAM 1500 bed, build-date and power-locking-tailgate configurations in which a tailgate-actuator limiter tab may fracture and allow the tailgate to unlatch while driving. NHTSA 22V904 / FCA ZB8 separately covers affected 2019-2022 RAM 1500 trucks whose misaligned tailgate strikers may prevent proper latching and allow the tailgate to open while driving. Either condition can release unsecured cargo and create a road hazard; VIN, model year and equipment determine the applicable campaign.
Common Symptoms
VIN, model year and bed configuration checked for U74, V44 and ZB8
unlatch event and cargo condition documented
latch, actuator limiter tab and striker alignment inspected
2013-2018 limiter-tab campaigns separated from the 2019-2022 striker-alignment campaign
How to Fix
Check the VIN for U74 / 18V486, V44 / 19V347 and ZB8 / 22V904. Have the dealer complete the applicable free remedy: repair the tailgate latch for the limiter-tab campaigns, or inspect tailgate-striker alignment to the box latch and adjust it if necessary for ZB8. Until campaign status and remedy completion are confirmed, verify the tailgate is latched before every trip and secure cargo independently. Outside those campaigns, inspect the latch, striker, actuator, limiter, wiring and alignment before replacement. Do not buy a latch, actuator or striker from this page; campaign eligibility, bed configuration, failed component, current part number and VIN fitment must be established first.
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 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 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 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 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 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.
