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.

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. 03

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.
