I bought a truck back in June. Well needless to say I've only put 1200 miles on it and here it sits in my driveway for 2 months out of the 2 1/2 that I've had it because the shop and also a gm dealer and 3 diesel mechanics that I know don't have a clue on what's wrong with it. Call Chris and he says take it to the shop and use the warranty ummm hello go dealer that is supposed to know everything about the truck they made and another shop and 3 diesel mechanics don't have a clue. Warranty don't mean nothing at this point. So I guess this $28000 truck will make a good lawn ornament. Will never do business again. Also his tag service is a joke also. My sister in law went to have a title transfer and registration done. They messed up the Vin number on the title and here it is 3 months later and her temp tag is expired again this will be the 3rd time she has to go back up there
