I am writing to express my concern about vehicle warranty coverage being provided by RAM (Stellantis NA) on their vehicles. I have a 2021 Ram 1500 which has a motor generator unit (MGU) which has failed due to a defect with the bearings. This has been diagnosed by the dealership and identified as covered under the emissions warranty. This diagnosis was made by Kolosso Ram in Appleton, Wisconsin in June of 2026. At this time I was advised that it could be a 6 to 8 month wait for parts because of a parts shortage due to the demand for the replacement part. My vehicle has been out of service since April while I maintain loan payments, depreciation of value, insurance and have no vehicle for transportation. A call to Ram was unsuccessful on two occasions to obtain any kind of relief in form of loaner vehicle or faster procurement of the part. Ram continues to build vehicles with this MGU unit while customers are stuck with inoperable vehicles some of with are still under original warranty or covered by the emissions warranty. The failure of Ram to ensure that customers have working vehicles is causing undue stress both emotionally and financially. This is also a potential safety issue as failed parts could put operators in an unsafe position.

Report issue to Stellantis/RAM who investigate and reported no issues. Vehicle was repaired by dealer body and repair shop. Upon pickup vehicle was not drivable due to "Wobble of Death". Shop determined it was a bad wheel. Vehicle drove okay but front-end vibration returned. Spoke with shop manager and stated tires has flat spots. Truck was parked for service a long time.

Engine

Read full complaint

I own a 2021 Ram 1500 with the 3.0L EcoDiesel Gen 3 engine. The vehicle has experienced diagnostic trouble code P00AF, indicating a turbocharger/variable geometry turbocharger (VGT) boost-control performance problem. I have already taken the vehicle to a Ram dealership for this same issue. The dealership performed a computer/software update in an attempt to correct the problem, but the P00AF issue continued afterward. I returned to the dealership and was told they could not reproduce the problem during their test drive and therefore could not repair it. The problem remains unresolved. I am concerned this may involve a premature failure or defect involving the turbocharger, electronic VGT actuator, or VGT control mechanism on the Gen 3 EcoDiesel. This is particularly concerning because I use the vehicle to tow an approximately 8,000-pound travel trailer. A turbocharger/VGT failure while towing could cause sudden loss of engine power, particularly under heavy load or while climbing grades, potentially creating a dangerous situation in traffic. The intermittent nature of the problem makes it difficult for the dealership to reproduce, but the fault continues to occur during actual vehicle operation. A software update has already been attempted without resolving the issue. I request that NHTSA investigate whether there is a pattern of premature turbocharger/VGT actuator or VGT mechanism failures resulting in P00AF on 2020–2023 Ram 1500 3.0L EcoDiesel Gen 3 vehicles. I can provide dealership repair documentation, diagnostic information, photographs, mileage, and other supporting information if requested.

Read full complaint

This vehicle was subject to NHTSA Recall 22V-767 / Stellantis Recall Z96 for a defective Bosch CP4.2 high-pressure fuel pump (HPFP) known to fail and release metal debris into the fuel system. The recall remedy (HPFP replacement) was performed at an authorized Stellantis/Ram dealership on 3/29/2024. On 8/9/2026, while driving the vehicle suddenly lost engine power and blocked the road in the left lane. The vehicle failed to restart and needed to be towed. The vehicle was independently inspected at Saddleback Automotive Service Center, Santa Ana, CA (RO# 130026). The technician documented diagnostic trouble codes P0087 (fuel pressure governor deviation, low pressure), P025C (fuel pump module control circuit low), and P016F (closed-loop fuel pressure control at limit, pressure too low) — all consistent with the same CP4.2 HPFP failure mode the recall was intended to remedy. Photographic and video documentation confirms metallic contamination in the engine oil and fuel filter screen. This failure occurred more than two years after the recall repair, and Stellantis (Case #97888077) has denied consequential-damage coverage citing the standard 24-month Mopar parts warranty on the replaced pump. I am filing this complaint because the recall remedy performed in March 2024 appears to have been inadequate: the vehicle experienced a recurrence of the same fault codes associated with the recalled component, and the resulting metal contamination caused catastrophic engine damage. I believe this indicates the recall remedy did not fully address the underlying defect and that other vehicles that received the same recall remedy may be at risk of the same outcome. I am requesting that NHTSA investigate whether the 22V-767/Z96 recall remedy is adequately preventing this failure mode in vehicles that received the HPFP replacement, and that this complaint be associated with any existing investigation into recurring CP4.2-related failures post-remedy.

EA23001 · High Pressure Fuel Pump Failure

Opened Mar 17, 2023 · No close date supplied

Status: open (inferred from source dates) · Fuel System, Diesel:delivery:fuel Pump

The Office of Defects Investigation (ODI) opened PE21-021 on October 14, 2021, to investigate incidents alleging a stall/loss of motive power as a result of high-pressure fuel pump failures in certain model year (MY) 2019-2020 Ram 2500, 3500, 4500, and 5500 heavy duty trucks equipped with 6.7L Cummins turbodiesel engines. During the investigation, ODI sought to determine if the related defect allegation was limited in scope to the recalled population. After review of information request response materials from both FCA and BMW, NHTSA determined that sufficient information to identify a comprehensive recall population could not be produced by FCA and BMW.During the investigation FCA filed recalls 22V406, 22E048, 22V767, and 22E087 which include vehicles not identified in the initial subject population by ODI. ODI also received recall 21V586, involving loss of motive power due to failed CP4 fuel pumps on certain BMW manufactured vehicles. An information request letter response received from BMW indicated that failed pumps on their vehicles were caused by an interaction between pump internal components and US market diesel fuel, leading to increased slip and eventual particle-generating wear surface. Additional work will be done to identify whether a similar root cause is associated with the FCA recalled population and if similar wear dynamics occur on pumps supplied to vehicle manufacturers other than those included in the recalled population.ODI has upgraded this investigation to an EA in order to 1) determine engineering specifications of internal pump components that are correlated with pump failure leading to loss of motive power or other safety related hazards, 2) identify vehicle populations equipped with alleged defective pump variants, 3) assess if vehicles equipped with alleged defective pump variants result in an unreasonable risk to motor vehicle safety and 4) gather and review any other relevant information related to high pressure fuel pump failure associated with the subject populations of recalls 21V586, 21V880, 21E094, 22V406, 22E048, 22V767, and 22E087.Review of the above information will allow NHTSA to confirm root cause and recall remedy viability, and identify and evaluate vehicle populations equipped with pump components that may pose an unreasonable risk to motor vehicle safety.The ODI reports cited above can be reviewed at: http://www-odi.nhtsa.dot.gov/owners/SearchNHTSAID using the following complaint identification numbers: 11257550, 11351441, 11361603, 11361616, 11365300, 11365426, 11365858, 11366401, 11372337, 11373793, 11374797, 11376793, 11377871, 11378173, 11384377, 11386063, 11387018, 11399710, 11402550, 11415339, 11418868, 11418870, 11427075, 11434276, 11436807, 11437226, 11437249, 11437273, 11437292, 11437294, 11437394, 11437399, 11437403, 11437405, 11437423, 11437528, 11437565, 11437579, 11437580, 11437590, 11437679, 11437744, 11437781, 11437842, 11437993, 11438006, 11438008, 11438121, 11438138, 11438155, 11438392, 11438629, 11439359, 11439879, 11440397, 11443030, 11446542, 11448163, 11453556, 11458918, 11460558, 11469337
