NHTSA Complaint #11552373 — 2021 RAM 2500

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.
