Sunday may 30 had truck towed to sawyer chevrolet in catskill NY. Truck will not go into any gear, selector moves but does nothing. Dealer was unable to detect the problem i was told gm engineering is now involved. This is the 13th week since purchasing the truck that is at a dealer with problems. I would like to know how long i will be without a vehicle again, and if gm is going to cover a loaner truck or a rental at there expense while i am without my vehicle?
