Last Wednesday, my 2015 Ram 1500 Ecodiesel through a check engine light upon start up. On Saturday morning, I took the truck to the dealer in order to have the code read and was advise that the truck was not leaving the dealer with me and I'd have to find an alternate vehicle in the interim. Originally the dealer thought that the CAT needed to be replaced, since they've done at least 6 in the past couple of months, but the code that my truck threw was a DPS related code. According to the dealer, Chrysler has yet to approve anything to be replaced or fixed and has stated that this it the first time that they are seeing this code. Can anyone shed some light if this is an accurate statement as I need my truck for towing purposes and at this time my truck is collecting dust while the technicians at the dealer and Chrysler attempt t come up with some type of resolution to the code? Also, my truck has only 9,800 miles on it and besides a required software update for the DEF injection system has been somewhat problem free. I just hope that this isn't a sign of what to expect in the coming years of owning this vehicle.
