I FILED A COMPLAINT ON 12/28/2004 REGARDING THE STEERING BOX BOLTS BREAKING LOOSE AND THE VEHICLE LOSING ALL STEERING CAPABILITY. GENERAL MOTORS WAS AWARE OF A SAFETY RECALL FOR THIS ISSUE, BUT IT DID NOT INCLUDE MY VIN. THEY DID PAY TO HAVE IT REPAIRED, BUT ALL THE DID WAS REPLACE THE BOLTS. MAYBE THEY SHOULD HAVE DONE MORE. ON 6/28/12, THE SAME THING HAS HAPPENED AGAIN WITH ALL THREE BOLTS BROKEN AND NO STEERING. I CONTACTED GM . AFTER TWO WEEKS OF CONVERSATIONS WITH GM, THEY ARE REFUSING TO ADMIT THERE IS A PROBLEM AND ARE ATTRIBUTING THE BOLTS AND STEERING BOX BREAKING TO THE AGE OF THE VEHICLE. ALTHOUGH THE SERVICE DEPARTMENT AT THE DEALERSHIP COULD NOT DETERMINE A CAUSE FOR THE BREAK OTHER THAN THE THREE BOLTS ARE BROKEN IN HALF. I AM LUCKY THAT MY SON WHO WAS DRIVING WAS NOT GOING AT A FASTER SPEED, OR THERE COULD HAVE BEEN A DEADLY CRASH. GM IS NOT WILLING TO LOOK AT THIS FURTHER OR TO PAY TO HAVE THIS REPAIRED. THEY ARE RECOMMENDING REPLACING THE BOLTS, THE STEERING BOX, AND THE LOWER INTERMEDIATE SHAFT AT MY COST WHICH IS ABOUT $900. I FIRST THINK THEY SHOULD ADMIT THIS IS A PROBLEM HAVING HAPPENED TWICE IN THE SAME VEHICLE AND TO LOOK FURTHER AT WHY THIS HAS HAPPENED. THEY DID HAVE A RECALL OF 99 CHEVY'S WITH THIS KNOWN PROBLEM. THIS VEHICLE HAD THIS PROBLEM AND NOW HAS IT AGAIN. MY CONCERN IS MOSTLY THE SAFETY OF THE VEHICLE AND WHETHER I WILL LET MY SON CONTINUE TO DRIVE THE VEHICLE ONCE IT IS REPAIRED. THEY SHOULD ALSO PAY TO HAVE IT REPAIRED. *TR

WE HAVE NOTICED THAT AREAS ON THE TRUCK WHERE RUSTING OUT. BUT WHEN THE BRAKES FAILED DUE TO THE LINES BEING RUSTED THROUGH I WAS VERY UPSET. I DO REALIZE THAT YOU MIGHT HAVE THIS FROM NORMAL WEAR BUT THE RUSTING IS EXTENSIVE.I WANT TO FILE A COMPLAINT AS I DO HOPE THAT THIS WILL NOT CAUSE AN ACCIDENT FOR SOMEONE ELSE. *JS

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.
