“I purchased a 2002 Gmc Sierra Denali in sept 2002 new from a local dealer. I am the primary driver and do not abuse the vehicle. I keep all the service work up on it thru the selling dealer. The problem that I have is that the qudarsteer control module went out and I called GM for a service request. Gm set up an appointment for me with the selling dealer to check out the problem. The dealership checked out my truck and told me that the qudrasteer module was bad and needed replaced. They got on theire computer and tried to locate a steering module. …”
