Hi: I have had mine new since Nov of 2016 and use it hard. After purchase the sending unit went out before delivery, after that no further problems until about 30k miles. Found that dealer replaced the sending unit but used same pump. Of course at a very busy intersection the truck died, literally. Found at a different dealership about what the selling Chrysler dealership had done. Cost Chrysler past the $25k mark when the fuel pump came apart and sent metal filings through out the fuel system. Everything had to be replaced in the fuel system and with special ordering (getting some of the parts off the assy line) the truck was down for a month. It was great that the 2nd dealership gave me a loaner the entire time. Since then have had no more major problems and have more than 76k miles on it now. Fuel mileage is ok, average about 25mpg. Towing about a 9k pound trailer getting between 19 and 21mpg driving around town and 70 to 80 on the road. Great truck, change the oil (Shell Rotella T6, 5w40) every 8k miles.
