The contact owns a 1999 Chevrolet Silverado 1500. The contact stated that there was a gap between the cab and the bed of the vehicle, and that the subframe of the vehicle was corroded. The check engine warning light was illuminated. The vehicle was taken to an independent dealer and the contact was informed that the catalytic converter needed to be replaced. The contact did not believe that the diagnostic result was not relative to the failure. Additionally, the contact stated that there were rust spots underneath the vehicle. The manufacturer was not notified of the failure. The failure mileage was approximately 134,000.

The frame and suspension has overly corroded. The frame is falling apart so bad that when I shut the driver's door chunks of metal fall to the ground. I've had it assessed and they say it should not be this bad. Even in Michigan

A COUPLE MONTHS AGO, I BOUGHT A 1999 CHEVY SILVERADO 1500 Z71 WITH 77,000 ACTUAL MILES THAT WAS FOR SALE ON CRAIGSLIST. THE GENTLEMAN ADVERTISED THE TRUCK IN EXCELLENT CONDITION, WITH NO RUST. WHEN I TEST DROVE THE TRUCK, I NOTICED IT NEEDED NEW A EXHAUST, AND SHOCKS. THE FOG LIGHTS WERE BROKEN, AND THE TURN SIGNAL LENSES WERE EXTREMELY CLOUDY. THIS IS NORMAL ON A OLDER VEHICLE. THE TRUCK HAS BEEN SETTING IN THE GARAGE, SINCE I DROVE IT HOME. THE GENTLEMAN TOLD ME THAT ALL THE RECEIPTS ARE IN THE GLOVE BOX, FROM WORK THAT WAS DONE ON THE TRUCK. I WENT THROUGH THE RECEIPTS, AND MOST OF THEM WERE FROM OIL CHANGES. SINCE I DON'T KNOW THE HISTORY OF THE TRUCK, IT'S A GOOD IDEA TO DO A TUNE-UP, AND CHANGE ALL THE FILTERS AND FLUIDS. I SPENT OVER A $1,000 NOT INCLUDING LABOR, ON SHOCKS, EXHAUST SYSTEM, TURN SIGNAL LENSES, FOG LIGHTS, FILTERS, FLUIDS, SPARK PLUGS, AND IGNITION WIRES. I JACKED THE TRUCK UP, SO THAT I COULD REPLACE THE EXHAUST. WHEN I CRAWLED UNDER THE TRUCK, I NOTICED THE FRAME AND FRAME CROSS MEMBERS WERE EXTREMELY RUSTY. THE TRUCK WAS ADVERTISED IN EXCELLENT CONDITION, WITH NO RUST! I STARTED REMOVING THE OLD EXHAUST, AND MY HAND WENT THROUGH ONE OF THE FRAME CROSS MEMBERS. THE GAS TANK HANGS FROM THIS PARTICULAR FRAME CROSS MEMBER. HOW CAN THE TRUCK BODY BE SO NICE, BUT THE FRAME BE COMPLETELY RUSTED OUT? IF WE HAD STATE INSPECTIONS, THERE'S NO WAY THE TRUCK WOULD PASS INSPECTION! I HAVE A 1995 GMC SIERRA THAT'S NEVER HAD ANY BODY RUST, OR RUST ON THE FRAME! I DID SOME RESEARCH ON THE INTERNET, AND FOUND OUT IT'S COMMON FOR THE FRAMES TO BE COMPLETELY RUSTED OUT ON THE GM TRUCKS BUILD FROM 1999 - 2007. THERE'S MILLIONS OF THESE TRUCKS ON THE ROAD, AND THE FUEL TANK, SPARE TIRE, OR REAR-END COULD EASILY FALL OFF! WHY ISN'T GM RECALLING THESE TRUCKS, AND REPLACING THE RUSTED OUT FRAMES? I HAVE A 2007 FORD F150 THAT DOESN'T HAVE ANY BODY RUST, OR FRAME RUST!

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.
