1994 GMC Sierra 2500 Problems

BRAKE FLUID LINES RUSTED AWAY ON BOTH SIDES, DIRECTLY BEHIND THE FRONT WHEELS. DURING REPAIR, AT A LICENSED REPAIR SHOP, IT WAS DISCOVERED THAT THE CHASSIS OF THE VEHICLE HAD, IN FACT, RUSTED COMPLETELY THROUGH WHERE THE BRAKE LINE CLAMPS WERE ATTACHED TO THE CHASSIS. THE RUSTING OF THE VEHICLE FRAME IS SO BAD THAT THE VEHICLE CANNOT BE SAFELY DRIVEN. I CONTACTED GM ABOUT THE PROBLEM. THEY ASSIGNED ME A SERVICE REQUEST NUMBER, #71-902016197 AND TOLD ME TO TAKE THE VEHICLE TO MY LOCAL GM DEALER AND HAVE THEM LOOK AT THE REPORTED DAMAGE. THE MECHANIC AT THE DEALERSHIP TOLD ME HE HAD SEEN THIS HAPPEN BEFORE BUT, NOT AS BAD AS THE RUST ON MY TRUCK. HE SAID HE BELIEVES IT IS CAUSED BY GM HAVING USED DISSIMILAR METAL SCREWS AND BRACKETS MOUNTED INTO THE TRUCK CHASSIS/FRAME. HE SAID HE WAS SURE THAT GM WOULD DO NOTHING ABOUT THE PROBLEM BUT THAT A FRAME REPAIR SHOP MAY BE ABLE TO REPLACE THE BAD SECTION. THIS IS CLEARLY A MANUFACTURING DEFECT THAT IS DANGEROUS AND MAY CAUSE INJURY OR DEATH SHOULD THE CHASSIS/FRAME FAIL WHILE THE TRUCK IS DRIVEN. IT SHOULD BE NOTED, THE TRUCK HAS BEEN WELL TAKEN CARE OF AND LACKS ANY OTHER RUST OR MAJOR DAMAGE.
