2021 RAM 2500 Complaints

Tailgate was repaired in February 2025 for issue under 22V-904 and then after the repairs were completed my tailgate dropped again resulting in damage to my tailgate.

Imminent lifter failure. Has a very loud tick. This is a very common and almost always catastrophic failure. This is on the 6.7L Cummins engine

The contact owns a 2021 Ram 2500. The contact stated that the vehicle was plugged in charging for about 15 minutes and unoccupied when it suddenly caught fire. The contact noticed smoke emerging from the vehicle. There were no warning lights illuminated before the failure. There were no reported injuries. The fire department was able to extinguish the fire. The contact mentioned that the fire spread to the home causing damage. There was no police report filed, crash, or air bag deployment. The vehicle was previously taken to the local dealer for NHTSA Campaign Number: 23V060000 (Electrical System) on December 20, 2024. The vehicle remained at the scene of the fire. The vehicle was not diagnosed or repaired as of yet. The manufacturer was not notified of the failure. The failure mileage was approximately 62,000.

Steering wheel started to make a snap noise when being turn either to the left or right. Didn't happen every turn but would come and go and became more frequent. Took to dealer for diagnosis and they said it's the same noise the 1500s have when the clock spring failed or broke. He tried to see if we had that recall since it was on some 1500s and some 2500s but ours wasnt so we had to pay out of pocket.

The engine has had camshaft and lifter failure multiple times. The dealership has replaced the camshaft and lifters twice already , and now they have failed a 3rd time which has lead to metal in oil lubrication system. This has caused further damage to the engine crankshaft bearings, in my case the engine was still running with a tapping/knocking noise. However, this can result in engine locking up and causing vehicle to no longer operate. In the event of engine failure this heavy duty truck will have no power steering or power brakes, leading to a high likely hood of collision. This issue is widespread for all 2019+ RAM 2500 with the 6.7L Cummins engine. Ram has done nothing to address the faulty parts , and continue to replace with same flawed parts, and not correctly addressing the damage done to the engine after a lifter failure. Ram HD 2500,3500,4500,5500 are still being sold currently with these faulty parts.

Heater quit working on driver side only. Still heats on passenger side. Took it into an ASE mechanic and they said they have seen multiple RAM trucks with this same problem. It isn't the heater or heater core. It is the Cooling system - gaskets failed, and coolant sprays across intake.

The engine cam and lifters are bad. Engine started knocking with only 30,000 miles. Had to have lifters and cam replaced

August of 2023 I took my truck in for a check engine light. The dealership diagnosed it and said my def tank senor is turning on the check engine light. They repaired it, when I picked up the truck they told me that "it was burnt out" and replaced the part. Now 14 months later it's having the same issue. Wondering if other ram 2500 owners are having this same issue and if it is a repetitive issue. The repair cost me over $963.00 dollars.

The integrated brake controller fails to provide braking to my travel trailer when attempting to stop. Multiple times this has pushed my truck into an intersection. There are no warning lights or failure messages. The brake controller is configured correctly as the issue has only been occurring the past few months and it was working as intended prior.

The passenger side seat belt retractor failed on this truck a couple of months ago. We had the parts replaced by the local dealer and did not think anything about it until our second truck also had the same issue and seriously hurt my mother. Report number 11597310. As the same part failed on two different trucks in a short period of time, we googled the issue and found lots of other RAM truck owners complaining of the same issue. We called RAM and they said there is no recall for the issue and there was nothing they would do. If this part fails, causing the retractor to lock and continue to "rachet" down on the passenger is could cause serious harm to people. My mother was hurt and we had to force the emergency release at the base of the seatbelt to get her out. If a person is alone in the vehicle when this part fails there is no way they could escape and it could cause a fatality.
