This is just unacceptable!! How many members do we have on here!!! I think GM needs to know that this GM truck owners community will not let this go and we should all stand behind Unhappy!!!!! If this is the kind of service we all are expected to receive, then I myself will switch my loyalty to a different brand that promises complete service and satisfaction!!! I'm very sorry for the trouble these people have gone through. its just plain WRONG!!!!!
