2021 RAM 1500 Problems

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.

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.

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.

The contact owns a 2021 Ram 1500. The contact stated that while attempting to start the vehicle, the instrument panel lights illuminated but the vehicle failed to start. The battery was replaced but the failure persisted. The vehicle was towed to the local dealer, who diagnosed that the RF Hub had failed and needed to be replaced. The vehicle was not yet repaired. The failure mileage was 81,000.

Driver side seatbelts issues, issues locking the buckle. Also car has engine light come up after emergency braking system error. Goes in to reduced power mode. If shut off and turn back on, truck is fine.

I initiated a turn and the steering wheel suddenly and forcefully moved in the opposite direction of my steering input. The steering wheel was pulled out of my hand. I was unable to maintain the intended steering direction and the vehicle was involved in a collision. This was not an intentional steering maneuver or ordinary loss of traction.

The contact owns a 2021 Ram 1500. The contact stated that while driving at an undisclosed speed, the "Service Electronic Steering Control", "Service Transmission", and the "Continue to Drive - Do not Shift or Turn off Engine" messages were displayed on the instrument panel, before the vehicle stalled. Additionally, the message "Shift to Park and Back to Drive", "Rear Braking Assist Unavailable", and "Self-Park Assist Disabled" messages were displayed on the instrument panel. The failure had occurred on several occasions. The contact stated that the vehicle was previously serviced under an unknown recall associated to the failure. The vehicle was taken to the dealer to be diagnosed; however, the cause of the failure was unknown. The dealer stated that the failure might be electrical. The vehicle was not repaired. The vehicle was towed back to the dealer; however, the vehicle was not yet diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

MGU unit failed / car seized in the middle of the road - sent in to be repaired Unsafe to be stuck in the middle of the road, could not even put the car in neutral to push out of the road Known problem that RAM and Stellantis know about and are not placing warnings. We were told by the dealership we were 5,000 in line for a new part and that it would take a year. No warnings, truck ran perfectly before

Recently this vehicle has triggered a check engine light. Upon further examination the code was related to an ignition #3. (CODES: P020C, PO1DO).

I received recall notification number 24V653000, Stellantis recall 75B. This recall is detailed as a software malfunction in the ABS control module to disable the electronic stability control system. This will cause the vehicle to fail. It was serviced at Don Davis Ram dealership in Arlington, Texas on November 11, 2025 and was advised they were going to do a software update. On July 27th , I contacted (formerly Don Davis) now Clay Cooley Ram dealership and spoke to a service representative, Jose Hernandez. I explained that the brakes feel very spongy and takes more time to slow the vehicle down (constantly have to brake several times when approaching other vehicles or at red lights). It is very noticeable and is dangerous for me and others on the roadway. He explained that I am now responsible for the diagnosis evaluation of $99.95 plus the fee to update the EBS software. Jose explained that everytime the brake system needs to be updated, then I am financially responsible for these fees because the 36,000 miles warranty has expired. I explained to him that I am guaranteed a "Lemon Law" protection in my purchase. In addition, this vehicle only has approximately 28,000 miles

The contact owns a 2021 Ram 1500. The contact stated that while driving at an undisclosed speed, the ABS warning light illuminated. Approximately six months later, while driving at an undisclosed speed, the check engine, ABS, stability control, and brake warning lights illuminated, and the "Auto Park Disabled," "Service Antilock Brake System," and "Service ABS System" warning messages were displayed on the instrument panel. The vehicle was taken to an independent mechanic shop, where it was diagnosed that the speed sensor and the wheel bearing needed to be replaced. Diagnostic trouble codes U0415, C0572, C053D, and C10F5 were retrieved. The speed sensor and the wheel bearing were replaced, but the failure persisted. The vehicle was then taken to a dealer, where it was diagnosed that the ABS module needed to be replaced; however, the vehicle was not repaired due to backordered parts. The manufacturer was notified of the failure. The failure mileage was unknown.

Purchase vehicle new and report issue with steering vibration and wandering feel after purchasing on multiple occasions when having the vehicle serviced by dealership. No issues found was the response each time, but condition continued. Front tire wear indicated something wasn't right. Replaced tires with OEM Goodyear tires even though symptoms persisted. While traveling this past winter in inclement weather vehicle lost traction while crossing a bridge as safe speed. Manage to correct but ended up in the guardrail. 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. Purchase a new set of tires, Michelins thinking it may be the brand that was issue. Condition persists with vibration wear showing tires already,

I initiated a turn and the steering wheel suddenly and forcefully moved in the opposite direction of my steering input. The steering wheel was pulled out of my hand. I was unable to maintain the intended steering direction and the vehicle was involved in a collision. This was not an intentional steering maneuver or ordinary loss of traction.

REAR WINDOW FRAME CRACKED AT BOTH CORNERS- WATER LEAKS INSIDE OF VEHICLE DURING RAIN. THIS CAN AFFECT ELECTRICAL COMPONENTS THAT ARE AT THE REAR CAB INSIDE THE TRUCK. I NOTICED THIS A MONTH AGO BUT DONT KNOW HOW LONG IT HAS BEEN THERE.

In January I experienced a “backlite leak” that allowed water to enter the cab of my vehicle. As a direct result of this water intrusion, my RFH (Radio Frequency Hub) module failed due to electrical shorting caused by moisture exposure. This failure was sudden and completely outside of my control and was not the result of misuse, neglect, or normal wear and tear. Not to mention the risk it put my family in as I was driving with my wife and daughter when the module failed and caused total power failure. I was driving down the road with my family in the vehicle when without any warning the truck completely shut down and didn’t have any power. I brought it to the dealership I bought it from and they stated they fixed the leak and replaced the RFH. Fast forward to this past week, there was another leak in the rear window. The dealership then stated it was a faulty back window unit that needs to be completely replaced. Stellantis (formerly FCA) previously acknowledged this defect through extended warranty coverage. However, my vehicle’s model year was later excluded despite being affected by the same known issue. This exclusion is particularly concerning given that the defect ultimately caused collateral electrical damage beyond the window itself. Given the documented nature of this issue, its prior recognition under extended warranty, and the risk of safety it put my family in I wanted to document this issue

Unknown, my Ram has a glue issue with the dashboard especially the passenger side of the vehicle which may affect the airbag operating correctly the dashboard is coming apart do to glue not properly installed on 2021 Ram truck.

Air bag light on. Needed temp start

I purchased a new 2026 Ram 1500 Rebel Crew Cab 4x4 from the John Heister Dodge Ram dealership, in [XXX] on XXX. The following day, I day i was notified of an open safety recall (NHTSA 26V-531) affecting the vehicle's rear visibility/backup camera system, which under certain conditions may fail to display the rearview image during a backing event. I later confirmed that this recall was posted on XXX -- four days before I purchased the vehicle. The dealer, John Heister Dodge Ram, did not disclose this open recall at any point during the sale, and the vehicle was sold to me with the defect unrepaired. This is a known safety-related defect, as new vehicles are required to have open recalls repaired before delivery. The recall remedy has not yet been performed on my vehicle.

Multiple times this has happened when I engaged in reverse the screen will be blank and can't see anything. It will take a couple of times of driving,parking and turning on and off the truck before it turns back on. This is a major safety concern as i can not see anything as i reverse. This does not happen every time but does happen often. I haven't had it checked out professionally because it hasn't been permanent but I do have Multiple videos of the problem recurring that I can send.

The contact owns a 2021 RAM 1500. The contact stated that while driving on several occasions at various speeds, the high beam headlights failed to illuminate while the button was depressed. The vehicle was taken to the dealer and was diagnosed and determined that the CSSM needed to be replaced. The vehicle was not yet repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 147,000.

Alt/Gen failure stopped the truck in the middle of an intersection No transmission power steering lights. Had to walk back home to charge the battery in a driving rain storm leaving the truck in the intersection.

I own a 2021 Ram 1500, which I purchased on March 29, 2024, as a certified pre-owned truck, and the primary issue involves a serious failure of the front wheel assembly. On three separate occasions, the front wheels have detached from the truck while it was in motion—on June 14, 2024, February 26, 2026, and most recently on April 17, 2026, when the left front wheel came off. I was driving the vehicle all three times during the incidents. Although the dealership has stated that repairs were completed after each incident, the problem continues to occur, indicating that the defect has not been properly resolved. The vehicle is available for inspection upon request, along with all supporting documentation. This defect creates a severe safety hazard, as losing the front wheels while driving greatly increases the risk of a crash and poses a danger to both me and others on the road. I have reported the issue to the dealership multiple times, and they have evaluated the vehicle, confirming a recurring and unresolved problem, along with additional major mechanical concerns that have not been adequately addressed under warranty. Despite having warranty coverage, I have paid high out-of-pocket costs for repairs, yet the problem has not been fixed. Despite these efforts, no effective or lasting repair has been made. The vehicle has not yet been inspected by the manufacturer, law enforcement, or insurance representatives, but I am willing to make it available for further review. Given the repeated and dangerous nature of this failure, I no longer feel safe operating the vehicle and I am requesting immediate assistance and a proper resolution.

While undergoing an annual vehicle inspection it was detected that ball joints have failed and are in need of replacement. This is a 2021 Ram 1500 with 77,500 miles. This seems to be a pre-mature failure of a critical component.

My bearings in my rear assembly has failed before 100K miles. In addition, I had to replace the eTorque generator before 100K miles.

While making a turn in a parking garage at low speed, I heard a loud popping sound. When I got out to inspect, I discovered that the front wheel had collapsed inward. There was no collision, curb hit, or external damage—just a spontaneous failure of the suspension system. This is the second time this same failure has occurred within the past year on this vehicle. The incident caused a complete loss of steering control, putting my safety at risk. Fortunately, I was not driving at high speed or on a public road when this occurred. There were no warning lights, noises, or other symptoms leading up to the event. The failed parts appear to include critical suspension and steering components (likely control arm, tie rod, or ball joint), and photos are available. The failure has not yet been inspected by the dealer or manufacturer, but the vehicle is available for inspection if requested. Given that this is a 2021 RAM with relatively low mileage, and it has experienced two nearly identical failures, this raises serious concerns about a potential manufacturing or design defect that could affect other vehicles. Attached are pictures from both incidents.

Driver side seatbelts issues, issues locking the buckle. Also car has engine light come up after emergency braking system error. Goes in to reduced power mode. If shut off and turn back on, truck is fine.

On 12-4-2025 I purchased a set of kumho mavis mountaineers apt tires at the Thomson GA. location. They didn't balance the tires when they were installed. So I had to go back for them to be balanced. After 5 months my truck was still riding really rough and the tires had worn considerably more than they should have so I called Mavis about this problem and was instructed to go to the Evans GA location on 5-22-2026 for a tire inspection. This location said all for tires were dry-rotted and I haven't had these tires for 7 full months and have put 22,000 miles on them. One tire has worn to the point of being slick and this is the only vehicle my family has right now. This has been on going since the date of purchase and there is a good chance these tires will cause an accident.
