We bought this truck to transport vehicles,....we bought what we believe to be the best,...a certified pre owned 2013 dually Denali,....have only had possession of truck for 6 months and every one of those months we were broke down for re occurring problems, putting us further under water....now this problem,...a injector went bad and took out a piston. Gm refuses to help and the same goes for the dealership. We are now bankrupt because of this truck with all its issues. Essentially we have a 60,000$ paperweight. We are currently stuck in South Dakota when we live in New Jersey,....I need help and or ideas,....
