Ya......... Brand new truck. I put a lot of highway miles on it. Got 21K on it... Been in the shop for a full week now. My advice to anyone looking to buy a new ram cummins... Dont buy one unless you are willing to delete that system right out of the gate. I'm a Ram guy.... but this piece of crap is absolutely driving me nuts. Been to two dealers and nobody can figure out what is wrong with it. DEF SYSTEM ERROR 150 miles until 5MPH max... If anyone knows anything about this please contact me. I would like to tell the dealer anything I can find out about this truck because clearley they have no freaking clue. I am suppose to leave to go to Nebraska on a deer hunt in the morning...its 3:48 and they still have not called me. Man am I upset..
