I have a 2014 Laramie that was really a good truck at first. Then I started experiencing loss of mpg. This was followed by the DEF sending unit having to be replaced. That entailed an entire new tank because the sending unit is part of the tank. About $1500. This has been followed by a knocking sound coming from the engine and guess what. The lower end bearings are bad making a new engine necessary at just under $14000. The total miles on the vehicle is 121203.
