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.

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 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.

My 2021 Ram 2500 6.7 truck quit on me driving down the road. When I raised the hood I could smell burned wires and see smoke. Luckily, it was raining or I think my truck would have burned up. I noticed melted plastic and burned wires on the drivers side of the truck. This particular truck had an Electrical system recall and shows to have been completed. (Safety Recall 13A/NHTSA 23V-060) If this recall was completed, maybe something else needs to be checked out. The truck is currently at a dealership to be repaired, but I will still be scared of it catching on fire because the dealership cannot tell me why or how the fire started.

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 flexible section of the exhaust coming from the engine that connects to the rigid sections of exhaust that contains the DPF components developed a hole in it. I reported that exhaust was smelled inside my cab and that sooty smoke could be seen coming up by my passenger side front window for almost a month. The Ram dealership told me the first two times I took it there that it was normal for regens to create smokey conditions. It was not til the third trip to the dealer, after being treated for bronchitis, GI problems, and extreme fatigue with elevated levels of CO in my blood that they finally lifted the truck and found an exhaust leak. I am concerned that the excessive regens caused by the faulty PM sensor that they just fixed caused the section of exhaust to fail. And if it is a widespread issue, others may also be exposed to dangerous levels of diesel exhaust.

My local Ram Dealership in Del Rio, Texas (Ram Country), has refused to repair my open recalls on my 2021 Ram 2500 Diesel. This includes the heater relay recall and the transmission dipstick recall. I have visited the dealership on at least 5 occassions and each time I am put on a new "waiting list". Ram Country has informed me that they get parts weekly and will call me to schedule needed repairs, however they never do. What can I do to get my recalls fixed, and finally closed. I get FCA recall notifications warning me to get my recalls completed, however again, my local Ram Dealer refuses to schedule a repair, and continues putting my on a waiting list, and has recommended that maybe I should get a new vehicle. For your information........I paid $75,000 for my truck 22 months ago, and I cant buy a new truck everytime the manufacturer refuses to make a diligent effort for recall remediation. I need help please..........

A high percentage of Ram owners with the 6.7 Cummins Engine are removing the Grid Heater due to a weak bolt that, over time becomes weak and falls down into the intake of the engine. The bolt will go directly into the engine block and cause catastrophic damage. There is an aftermarket fix which is a heater element installed into the intake horn itself instead of directly on top of the flat intake surface.

At a stop light after 10 min of normal driving on country and city roads my truck started smoking from front passenger wheel well. Smoke intensified and quickly turned black. Immediately pulled over and found flames burning through front passenger wheel liner and from around passenger side battery and intake filter.

Fire melted through battery case leaking battery acid, parts of the intake filter housing, all surrounding electrical wiring and completely through wheel well. Was building in intensity until put out with fire extinguisher. Truck was purchased in June 2021 and had 0 active recalls. Truck was completely stock.
