SEVERE UNDER BODY/FRAME ROT. THE UNDERCARRIAGE AND FRAME OF THE VEHICLE IS SEVERELY CORRODED. THERE ARE NUMEROUS ROT HOLES IN THE BED FLOOR TO THE EXTENT THAT YOU CAN NOT WALK ON THE BED.

BRAKE LINES ROTTED ALONG WITH ENTIRE BRAKE ASSEMBLY ON REAR TIRES, CALIPER AND HOUSING THAT HOLDS CALIPER ROTTED. ENTIRE PORTION OF METAL THAT HOLDS THE LEFT TAILGATE HINGE ROTTED AWAY AND IS NOW GONE. TAILGATE CAN NOT BE OPENED. UPON TAKING THE VEHICLE FOR AN INSPECTION STICKER I WAS TOLD THE VEHICLE WAS FALLING APART AND I WAS WARNED THAT I SHOULD NOT BE DRIVING THE VEHICLE. I WAS TOLD THE ENTIRE FRAME WAS ROTTED TO THE POINT THAT REPAIR WOULD NOT BE A COST EFFECTIVE CHOICE. UPON CONTACTING DEALERSHIP I WAS TOLD THERE WERE NO RECALLS AND THERE WAS NOTHING THEY COULD DO. *TR

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
