On the 2013-2025 RAM 2500 6.7 Cummins, the 2013+ RAM 2500 6.7L Cummins diesel DEF (Diesel Exhaust Fluid) system is plagued with failures of the DEF heater, DEF pump, DEF injector, NOx sensors, and SCR catalyst. The DEF system is required for emissions compliance, and when it fails, the truck enters a "limp mode" that limits speed to 5 mph after a countdown timer expires. DEF heater failures are most common in cold climates where the fluid freezes and cracks the heater element. TSB 18-018-20 addresses DEF heater and quality sensor issues. The NOx sensors (inlet and outlet) fail frequently at $300-500 each.
Common Symptoms
DEF system warning light or message
Speed limited to 5 mph (limp mode)
Check engine light with SCR-related codes (P20EE, P2BAD, P2201)
DEF quality poor message despite fresh fluid
DEF tank not reading correct level
Truck will not restart after shutdown (DEF lockout)
Ammonia smell from exhaust
How to Fix
Diagnose with Cummins INSITE or wiTECH to identify the specific DEF component failure. Common repairs: DEF heater replacement ($400-800, Mopar 68322877AA), DEF pump/injector assembly ($600-1,000), NOx sensor replacement ($300-500 each, two sensors). If SCR catalyst is failed, replacement costs $2,000-3,500. Check TSB 18-018-20 for updated DEF heater and quality sensor procedures. Use only API-certified DEF fluid (ISO 22241 standard). Avoid storing DEF over 1 year as it degrades.

On the 2007-2024 RAM 2500 6.7L Cummins Turbo Diesel, the Holset HE351VE variable-geometry turbocharger uses an electronically controlled actuator (the geartrain and control board that moves the vane sliding ring) that is a well-documented failure point, often before 100k miles. Soot and carbon buildup, rust/corrosion binding the vane arm, worn actuator gears, or a corroded circuit board (from coolant/water intrusion) cause the actuator to stop positioning the vanes correctly. The truck then either spools quickly but chokes at mid/high rpm or spools slowly with a big loss of low-end torque, and typically drops into limp mode. Owners on Cummins forums report repeat failures and note the unit must be scan-tool programmed to the specific turbo after replacement.
Common Symptoms
Loss of power / limp mode
Slow or no turbo spool
Excessive turbo whistle or lack of boost
Check engine light with turbo actuator codes
Sluggish acceleration when towing
Actuator gear grinding/clicking on startup
How to Fix
Replace the VGT actuator with a genuine remanufactured Holset unit (common OEM/service PNs for 2007.5-2012: 2837675 / 4034315HX / 4046534 / 4049828; later 2013-2018 trucks use the updated HE300VG actuator). The new actuator MUST be calibrated/aligned and programmed to the turbo with a Cummins-capable scan tool (wiTECH) or a pre-programmed 'corded' plug-and-play unit such as the BD Diesel corded HE351 actuator. If the vane mechanism itself is seized with soot the whole turbo may need replacement. Clean the vanes/EGR side and address coolant leaks that corrode the board to prevent recurrence.

On the 2014-2024 RAM 2500 6.4L 392 HEMI V8 gas, gas RAM 2500s with the 6.4L (392) HEMI V8 suffer a documented valvetrain defect in which the roller lifter needle bearings fail, the roller stops rolling and drags across the camshaft lobe, wiping out the lobe. The failure is linked to the truck's Multi-Displacement System (MDS/cylinder deactivation): when cylinders are deactivated, oil delivery to the affected lifters is restricted, starving the roller bearings. Owners report onset as a metallic 'HEMI tick' progressing to misfire, dropped cylinder and catastrophic top-end damage. A class-action lawsuit (Petro, et al. v. FCA US LLC, Case No. 1:22-cv-00621, whose named plaintiffs include a 2020 RAM 2500 owner) alleges FCA knew of the defect since at least 2012 and failed to disclose it. There is no safety recall, so repairs typically fall on the owner once warranty lapses.
Metallic ticking/tapping from top of engine (HEMI tick)
Engine misfire, rough idle
Check engine light with misfire codes
Loss of power / dropped cylinder
Metal shavings in oil
Loud knocking as failure progresses
How to Fix
Diagnosis via oil-analysis metal content, cylinder-specific misfire/lifter tick, and cam inspection. Accepted repair is replacement of all 16 lifters plus the camshaft (and any damaged pushrods/rockers); severely scored cams or circulated bearing debris often force a long-block or complete engine replacement. Many owners/shops disable/delete MDS during the rebuild to prevent recurrence. Frequent oil changes with correct-spec oil are the preventive measure.
On the 2007-2024 RAM 2500 6.7L Cummins Turbo Diesel, the intake grid (air) heater warms incoming air for cold starts and carries up to ~200 amps through a small threaded stud/bolt secured by a 10mm nut on the intake plenum. Over years of high-current heat cycling the bolt/nut connection deteriorates, arcs, and can break loose. Because it sits directly above the intake runner, gravity pulls the heavy steel stud straight into cylinder #6, destroying the piston, valves, and cylinder head, often the entire engine. Banks Power has documented 200+ failures, some at as little as 40,000 miles. Stellantis has NOT recalled the grid heater assembly itself (a separate 2021-2022 relay recall Y08/Y76 addressed sticking relays, not the bolt).
Common Symptoms
Loud engine knock / metallic clatter
Sudden power loss
Rough running or misfire on cylinder 6
Loose grid heater power terminal
Check engine light with grid heater codes
Hard cold starts
How to Fix
Do the preventive 'wiggle test': with the engine off, grab the external power terminal (10mm bolt) and try to move it; any movement means the internal stud is loosening and needs immediate attention. Best fix is to replace the stock grid heater with a redesigned unit that eliminates the internal bolt, such as the BD Diesel Killer Grid Heater upgrade kit (PN 1041520, fits 2007-2024), or install a grid-heater delete/relocation plate (Fleece/Pusher) if legal in your area. Genuine Cummins intake air heaters (e.g., 3970000 / 3970001) are direct replacements but retain the original design.

On the 2003-2025 RAM 2500, the RAM 2500 (and 3500) with solid front axle experiences a violent front-end oscillation known as "death wobble" that occurs at highway speeds (45-65 mph), typically triggered by hitting a bump or pothole. The steering wheel shakes uncontrollably and the entire front end vibrates violently, making the truck nearly undrivable until the driver slows to a stop. The issue is caused by worn or loose front-end components working together in resonance: track bar, ball joints, tie rod ends, unit bearings, steering stabilizer, and steering gear box. NHTSA has received thousands of complaints. TSB 19-001-14 REV.B addresses front axle steering linkage inspection.
Common Symptoms
Violent steering wheel oscillation at highway speed
Entire front end shaking after hitting a bump
Steering wheel impossible to control during wobble event
Must slow to a stop to regain control
Wobble typically occurs between 45-65 mph
Front tires showing uneven wear patterns
Loose or clunking feeling in front end over bumps
How to Fix
Death wobble is a SYSTEM issue - all front-end components must be inspected. Start with: 1) Track bar and track bar bracket (most common initiator) - replace with upgraded aftermarket (Synergy, Carli) $200-400. 2) Ball joints - replace with Dynatrac or Synergy heavy-duty units $300-600/pair. 3) Tie rod ends - Moog or Synergy $100-200/pair. 4) Unit bearings - Timken or Moog $200-400/pair. 5) Steering stabilizer - Fox or Bilstein dual stabilizer $200-400. 6) Steering gear box - check for play, tighten or replace $400-1,200. Address ALL worn components, not just one. TSB 19-001-14 REV.B covers the inspection procedure.

On the 2003-2025 RAM 2500, the RAM 2500/3500 steering gear box (power steering box) develops fluid leaks from the input shaft seal and sector shaft seal, and excessive play in the steering. The leak starts as a slow drip and worsens over time, eventually causing low power steering fluid and potential pump damage. Excessive play manifests as a "dead zone" in the steering where the wheel moves 1-2 inches without the wheels turning. The gear box also loosens from the frame due to the high stresses of the solid front axle design. Tightening the adjustment screw on the gear box can temporarily reduce play, but eventual replacement is needed.
Common Symptoms
Power steering fluid leak at steering gear box
Excessive play or looseness in steering wheel
Dead zone when turning steering wheel
Wandering on highway - constant steering corrections needed
Whining noise from power steering pump (low fluid)
Steering gear box loose on frame mount
Power steering fluid on ground under truck
How to Fix
For minor leaks: Try a power steering stop-leak additive as a temporary fix ($15-20). For the input shaft seal leak, the seal can be replaced without removing the gear box ($100-200 labor). For excessive play: Adjust the sector shaft screw (1/4 turn clockwise) per TSB procedure - this takes up slack but is a temporary fix. For complete resolution, replace the steering gear box with OEM Mopar (68164717AA) or upgraded RedHead Steering Gear ($800-1,500 installed). Retorque or replace frame mounting bolts (they stretch over time).

On the 2010-2025 RAM 2500, the rear driveshaft U-joints in the RAM 2500 fail prematurely, particularly on trucks used for towing. The factory U-joints are undersized for sustained heavy load use, and the grease fittings (where present) are often overlooked during maintenance. Symptoms start with a clicking or clunking sound during acceleration and deceleration, progressing to vibration at highway speed. Complete U-joint failure can cause the driveshaft to drop, which is a serious safety hazard.
Clunking noise during acceleration and deceleration
Vibration at highway speeds (55-70 mph)
Clicking sound when shifting from Drive to Reverse
Visible rust or play in U-joint when inspected
Driveshaft vibration felt through floor of truck
How to Fix
Replace the U-joints with heavy-duty aftermarket units rated for towing. Spicer Life Series 5-1350X or 5-760X are popular upgrades. Replace both driveshaft U-joints at the same time. Grease the new U-joints immediately after installation and at every oil change interval thereafter. If the driveshaft yoke ears are worn, the driveshaft must be replaced. Budget $200-$600 for parts and labor.
Owner tips & cautions
TipSpicer Life Series U-joints (5-1350X or 5-760X) are the go-to upgrade for towing. They are stronger than OEM and have greaseable fittings. Grease at every oil change.
WarningDo not ignore U-joint clunking — a failed U-joint can cause the driveshaft to drop at highway speed, which can vault the truck or damage the road. This is a safety-critical repair.
On the 2010-2025 RAM 2500, the BorgWarner BW4470 (part-time 4WD) and BW4494 (full-time 4WD) transfer cases develop fluid leaks at the front and rear output shaft seals and at the case halves. The leaks are often slow and go unnoticed until the fluid level drops enough to cause whine, grinding, or failure to engage 4WD. Trucks used for towing are more susceptible due to higher operating temperatures.
Low fluid level on transfer case dipstick or fill plug
How to Fix
Replace the leaking output shaft seal(s). If the leak is at the case half, reseal with Mopar RTV sealant during reassembly. Refill with the correct fluid: Mopar 05166184AA (BW4470) or equivalent ATF+4 (BW4494). Check fluid level at every oil change, especially on trucks used for towing. Seal replacement runs $200-$500 depending on which seal.
Owner tips & cautions
TipAdd a magnetic drain plug when servicing the transfer case — it catches metal shavings before they circulate and cause wear. Check fluid level at every oil change.
TipIf your truck tows regularly, change the transfer case fluid every 30,000 miles instead of the factory 60,000-mile interval. Heat from towing breaks down the fluid much faster.
On the 2019-2025 RAM 2500 6.7L Cummins, the 2019+ RAM 2500 with the 6.7L Cummins diesel uses a Bosch CP4.2 high-pressure fuel injection pump that is prone to catastrophic self-destruction. The CP4.2 relies on diesel fuel for internal lubrication, and any contamination, water intrusion, or low fuel levels cause the pump to disintegrate, sending metal shavings throughout the entire fuel system. This contaminates fuel injectors ($500+ each x6), fuel rails, fuel lines, and the fuel tank, requiring a complete fuel system replacement costing $8,000-12,000+. The previous-generation CP3 pump was far more reliable. Multiple class-action lawsuits have been filed against Stellantis/Bosch.
Check engine light with fuel pressure codes (P0087, P0088, P228D)
Excessive cranking before starting
Fuel filter clogging frequently
White or black smoke from exhaust
How to Fix
If the CP4.2 has failed, the ENTIRE fuel system must be replaced or thoroughly cleaned: fuel pump, all 6 injectors (Bosch 0445120413), fuel rails, high-pressure fuel lines, fuel tank (or professionally cleaned), and fuel filter. Total cost: $8,000-12,000+ at dealer. Prevention: Install a FASS or AirDog lift pump system ($800-1,200) that provides additional fuel filtration and water separation before the CP4.2. Some owners proactively replace the CP4.2 with a CP3 conversion kit ($3,000-4,500) from S&S Diesel Motorsport or Fleece Performance for permanent reliability.

On the 2007-2024 RAM 2500 6.7L Cummins Turbo Diesel, the EGR cooler routes hot exhaust through a coolant-jacketed heat exchanger before recirculating it into the intake. Heavy soot loading progressively plugs the cooler and EGR valve, first showing as slight off-idle hesitation and rising EGTs, then triggering EGR flow/performance codes and limp mode. Worse, a clogged, thermally stressed cooler can crack internally and leak coolant into the exhaust/intake stream, causing white smoke, coolant loss, and potential hydrolock or catastrophic engine damage. Cummins service intervals call for cleaning the EGR valve/cooler roughly every 67,500 miles (2007.5-2018) or 75,000 miles (2019+), which many owners never perform.
Clean or replace the EGR cooler and valve. Genuine replacement cooler OEM PNs include 68048988AA (and related 4988885 / 4988884 / 68048991AA / 68444764AA for later trucks); an upgraded H-core cooler (e.g., BulletProof Diesel) resists cracking and clogging better than stock. Replace the EGR valve if the pintle is coked. Keep the DPF/regen system healthy, avoid excessive short-trip idling, and inspect/clean on Cummins' recommended interval to prevent the crack-and-coolant-loss failure mode.

On the 2007-2024 RAM 2500 6.7L Cummins Turbo Diesel, the 68RFE 6-speed automatic behind the Cummins is prone to torque converter shudder and lockup failure. The factory converter's clutch material and heat control are marginal for the Cummins' torque, so the torque converter clutch (TCC) chatters, slips, or refuses to hold lockup, felt as a low-speed vibration like driving over rumble strips. The TCC regulator valve wears its bore in the valve body, making apply pressure erratic. The resulting heat contaminates the fluid and cascades into planetary and clutch-pack damage. Heat is the number-one killer, especially when towing; fluid temps regularly over 200°F accelerate failure.
Shudder/vibration around 40-55 mph (converter lockup)
Slipping or flaring on lockup
High transmission temperatures when towing
Harsh or delayed shifts
Burnt-smelling ATF+4 fluid
Check engine light with TCC codes
How to Fix
Replace the torque converter with a stronger billet/multi-disc unit (e.g., Sun Coast, BD Diesel, or Suncoast triple-disc) rather than another stock converter. Rebuild or upgrade the valve body / TCC regulator valve (Sonnax) to restore correct apply pressure. Add an auxiliary transmission cooler and use the correct ATF+4 fluid, and consider a deep pan and improved fluid capacity for towing. Address early to avoid a full transmission rebuild.

On the 2010-2025 RAM 2500 6.7L Cummins, the cast iron exhaust manifold on the 6.7L Cummins turbo diesel cracks due to thermal cycling stress, particularly near the center cylinders (#3 and #4). Cracks allow exhaust gases to escape, creating a ticking noise on cold start that diminishes as the manifold expands when warm. Exhaust leaks can also send soot into the engine bay and affect turbocharger performance by reducing exhaust backpressure to the turbine.
Ticking or tapping noise on cold start that fades when warm
Exhaust soot or staining on engine bay components
Slight exhaust smell in engine compartment
Reduced turbo boost in severe cases
Visible crack on manifold surface upon inspection
How to Fix
Replace the cracked exhaust manifold. OEM replacement (Mopar 68408593AA) or aftermarket upgraded manifolds from BD Diesel or Industrial Injection are available. Aftermarket options are typically thicker castings less prone to re-cracking. Always replace the exhaust manifold gaskets and inspect/replace any stretched or corroded manifold studs. Budget $600-$1,500 for parts and labor.
Owner tips & cautions
TipBD Diesel and Industrial Injection make thicker aftermarket manifolds that resist cracking better than OEM. Worth the upgrade if the factory manifold has already cracked once.
WarningAlways inspect manifold studs during replacement — corroded or stretched studs will snap during removal. Have an extractor set and replacement studs on hand before starting the job.
On the 2014-2022 RAM 2500, the center high-mounted third brake light on RAM 2500 trucks is a chronic water-leak point across both the 4th (2010-2018) and 5th (2019+) generations. The thin foam gasket sealing the lamp housing to the cab roof compresses, dries out and degrades, letting rainwater pass through the mounting holes into the cab sheet metal. Because of how the roof slopes, water runs down and shows up as staining on the headliner in the rear corners above the back glass. Beyond cosmetic damage, water frequently drips onto interior electronics — owners report soaked and corroded Body Control Modules (BCM) and other connectors, escalating a cheap seal failure into an expensive electrical fault.
Common Symptoms
Water stains on headliner in rear corners
Dripping water inside cab after rain/wash
Wet rear seat or floor
Musty smell
Electrical gremlins / BCM faults from water intrusion
How to Fix
Remove the third brake light (typically two Phillips screws), reseal or replace the degraded foam gasket with a fresh thicker gasket, and apply butyl/RTV sealant around the mounting studs; replace the lamp assembly if cracked. Dry the headliner and inspect/dry the BCM and connectors. If water reached the BCM, cleaning or module replacement plus reprogramming may be required.
