2021 Ram 2500 Engine Problems

Your EGR cooler is cracked and leaking coolant, which is burning off in your engine. Ram has issued recalls for this same part on other model years, but not yours, even though the issue affects multiple trucks with the same component. The dealership has suggested contacting NHTSA about a potential recall, as this problem has been reported to cause fires in some trucks.

After starting your vehicle, you noticed a fire smell entering the cab. When you exited and checked the engine, smoke was coming from it. The engine then caught fire and the vehicle was completely destroyed within 10 minutes.

Your engine has a loud ticking noise that indicates a lifter is about to fail. This is a known issue with the 6.7L Cummins engine and typically leads to severe engine damage if not addressed quickly. The repair will likely require replacing the failed lifter and may involve significant engine work.

Your engine's camshaft and lifters have failed multiple times despite dealer replacements, and metal debris from the failures has damaged your crankshaft bearings. You may hear tapping or knocking noises, and in a worst-case scenario, the engine could shut down completely, leaving you without power steering or power brakes and creating a serious collision risk. Fixing this typically requires replacing the camshaft, lifters, and potentially the crankshaft bearings, along with a complete oil system flush to remove metal contamination.

Your driver-side heater has stopped working while the passenger side still heats normally. A mechanic found that this is caused by failed cooling system gaskets allowing coolant to spray across the intake, not a problem with the heater itself. This same issue has been reported on multiple RAM trucks. The repair will likely involve replacing the failed gaskets in the cooling system.

Your transmission makes a high-pitched whining noise when you shift gears during acceleration. You've taken the truck to the Ram dealership four times, and while FCA approved a repair involving a small transmission part, the noise persists after the fix. The dealership may need to investigate further or consider a larger transmission component replacement.

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.

When placing the truck in first gear to control speeds on steep declines both on and off road the vehicle's RPMS will climb significantly and the truck will accelerate abruptly under it's own power until it reaches 21-25mph. At which point the RPM's come down and truck begins to slow as expected. Once truck reaches a speed of 11mph the RPM's begin to climb again and the truck accelerates(Not due to gravity, but accelerates under it's own power) aggressively. It will continue to do this pattern until you either reach flat ground or switch gears. Safety is at risk due to uncontrolled descent down steep mountain passes. Constantly having to apply breaks to prevent the truck from going off the road. This safety liability is exacerbated when towing a trailer. I have reported the issue to the dealer multiple times with their claim that the vehicle is behaving as expected. I have not experienced this with any other vehicle. This is not common vehicle behavior. No warning Lamps, Messages or Other symptoms. Reproducible on any hill with steep enough descent.

The vehicle was taken to a dealer where it was diagnosed that the ECM needed to be updated. The ECM was updated but the failure persisted. The manufacturer was notified of the failure. The failure mileage was 37,510.

3 months ago at around 23,000 miles, my truck had a P0302 Cylinder 2 misfire code, dealership “reset” the vehicle and code didn’t return. 3 weeks ago, cylinder 2 started having a loud tapping noise after the vehicle was fully warmed up. Vehicle has been at the dealership for 1 week with zero communication from the dealership or from the RAM caseworker. No rental car has been offered.

I recently bought this truck used from a Ford dealership. The next day when I was taking my wife for a short drive. I noticed the engine light was on the dash display. I the same time the truck started accelerating Like it was on cruise control and returning to a higher speed. The cruse control was not set when I tried to access the cruse control I would get the message that it was unavailable at this time. I had to stop the truck and turn the truck off. When I restarted the engine light was still on, but the acceleration stopped. I drove to the dealership to see if they had any information or recalls but by the time, I got there the engine light was off and their computer did not tell them anything. This has now happened two times. The dealership says I must bring the Truck in while this is happening. for them to get a reading. This is not my primary vehicle, and I don't drive it all the time and it is 45 minutes from any dealership. The uncontrolled acieration is a safety issue. The problem has not been reproduced Dealer thay had no idea what was happening. The warning lamp engine and the cruse control not available message., I am wondering if anyone else has had the problem?

The contact owns a 2021 Ram 2500. The contact stated that after the vehicle was repaired under NHTSA Campaign Number: 22V835000 (Power Train) he became aware that the replacement dipstick was 15-inches long instead the previous 44-inches in length. Additionally, the dipstick stated that it was not intended to check the transmission fluid level. The manufacturer was notified of the issue and advised the contact to take the vehicle to dealer to have the fluid level checked. The contact was not provided information for the change in the dipstick. The failure mileage was approximately 42,000.
