This is a 2022 Ram 2500 Long Horn with teh 6.7L Cummings Diesel. I have owned it for 30 days and it has 1475 miles on the odometer. The Service DEF System came on and after talking with the local dealership, the DEF sensor and or DEF pump has failed due to the DEF freezing. They have explained that this is a know issue and has affected the 2019 to present model year. After doing extensive research on neumorous blogs, it is a much larger problem than the dealer is letting on. It appears to be created by a design change that took place in 2019 and is caused by the DEF fluid itself freezing in the tank damaging the DEF sensor. DEF freezes at -12 so those of us living in areas where it may hit -12 are all affected by this situation and in reality, have spend 60k plus on a vehicle that we cannot operate. …

March 10,2023 2019 Ram 2500 Cummins 6.7L Diesel I picked up my truck from the dealership this morning, after they did the outstanding CP4 fuel pump recall. I drove the vehicle home (approx 20) miles. Parked the car in the driveway for about 3 hours. Then took a short trip to the store. After the store, when leaving the parking lot I noticed an electrical/plastic smell. Within in seconds smoke started to come through the air vents. I pulled the truck over, turned off the truck, open the hood when fire exspelled from the engine compartment. Immediately call the fire department. They arrived in minutes to put out the fire, but at that point the whole front end of the truck was on fire and smoking (dense white/gray smoke). Then there was a loud burst of flame that came from the engine compartment. The fire worked its way into the cab compartment, burned it completely. The truck is totaled.
