NHTSA Complaint #11507743 — 2022 RAM 2500

I was notified of the Particulate Matter (PM) Sensor not being installed in the exhaust aftertreatment system of my vehicle on a post delivery survey I received. The dealership's service department has no idea about this sensor not being installed by the factory, and the response from the letter stated there would be a recall soon to have the PM sensor installed, but that has not happened over a year later. The ECU will need an update once the sensor is installed, which would allow the Diesel Particulate Filter (DPF) gauge to function. This poses a risk to unknown regeneration occurrences, which could lead to a fire if the vehicle is parked next to dry grass or other flammable material. It also poses a significant risk for exhaust system emissions component failure in the future. The sensors and software update need to be completed as soon as possible.
