DEF sensor malfunctions, threatening to limit vehicle to 5 mph or stop completely. This is because DEF fluid freezes in cold weather. Sensor reads that DEF tank is empty, even when it is full. Contacted local dealer who confirmed the issue and noted that it is a prevalent problem and he has a backlog of trucks with the same issue. I consider this a safety issue, as I could be stranded on the road in winter conditions or not have access to my vehicle in case of emergency. Google search shows that this is a significant issue affecting many people. Dealer said that the only solution is to put the vehicle in a heated garage for several days to defrost the DEF and allow the sensor to reset. They currently have a backlog of several weeks. And then what happens when you get it back" You hope it doesn't refreeze and strand you on the road somewhere"

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. Either the DEF needs to be redesigned to not freeze or Ram needs to redesign, or go back to what they had that worked, the DEF system. This is not only an emmisions issue it is also a saftey issue. If the DEF system does not work, the vehicle does not meet the current emmisions standards. If the vehicle goes into limp in mode, you have strandad customers along side the road becomming a safety hazard and if the limp in mode happens at highway speeds, who knows the effectis on the vehicle as it slows down and creats a hazzard on the highway. Please work with RAM to remedy this situation so those of us with a 61k + boat anchor can use their trucks as they intended to when they spent their hard earned money to do so.
