Failure of underbody/frame rust undercoating. The undercoating has completely flaked off the frame of my truck with 90k miles. I am the only owner of this vehicle which has been garaged since day one. The vehicle is also rusting thru from the underside of the hood. I have contacted GMC about this issue both in person & on the phone. They have denied any liability in this matter.
