TL*THE CONTACT OWNS A 1999 CHEVROLET SILVERADO 1500. THERE WAS A RECALL ISSUED ON THE BRAKING SYSTEM, WHICH INCLUDED THE RIMS, EMERGENCY BRAKES, AND ROTORS. THE ABS LIGHT ILLUMINATED WHEN THE VEHICLE WAS STARTED, BUT THEN DIMMED AFTER A FEW MINUTES. THE FAILURE OCCURRED FOR OVER A WEEK UNTIL THE LIGHT REMAINED COMPLETELY ILLUMINATED. THE DEALER STATED THAT THE ABS CONTROL BOX FAILED. CHEVROLET STATED THAT THE VEHICLE HAD TOO MANY MILES TO BE REPAIRED UNDER THE RECALL. THE CONTACT BELIEVES THAT IF THERE WAS A RECALL ON THE ENTIRE BRAKING SYSTEM THAT WAS REPAIRED WHEN THE VEHICLE HAD THE SAME MILEAGE, THEN THE ABS CONTROL BOX SHOULD BE REPAIRED UNDER THE RECALL AS WELL. THE FAILURE MILEAGE WAS 217,000 AND CURRENT MILEAGE WAS 224,000.

PLASTIC PIECES FELL OUT ONTO THE FLOOR. IT APPEARED TO BE A PLASTIC PIECE THAT HELD THE LOCKING PIN FOR THE SEAT. THE TEMPERATURE THAT DAY HAD BEEN BETWEEN 20 AND 30 DEGREES F. THE VEHICLE HAD TO BE DRIVEN HOME. WHEN YOU APPLIED THE BRAKE, THE SEAT MOVED FORWARD. WHEN YOU APPLIED THE GAS, THE SEAT MOVED ALL THE WAY BACK. *TR

TL*THE CONTACT OWNS A 1999 CHEVROLET SILVERADO 1500. THE CONTACT PLACED BAD GASOLINE IN HIS VEHICLE ONCE AND HAD TO REPLACE THE FUEL TANK. WHILE REMOVING THE TANK, HE NOTICED THAT THE FRAME WAS CORRODED AND HAD SPREAD TO THE REAR BUMPER. THE AUTO GARAGE STATED THAT THE FRAME NEEDED TO BE REBUILT. THE REPAIR COST WOULD EXCEED $1,500; THEREFORE, THE CONTACT IS UNABLE TO HAVE THE VEHICLE REPAIRED AT THIS TIME. THE MANUFACTURER FILED A REPORT AND SENT AN INVESTIGATOR TO INSPECT THE FRAME, AND CONCLUDED THAT THEY WERE NOT GOING TO ASSIST WITH THE REPAIR BECAUSE THE VEHICLE IS OVER EIGHT YEARS OLD. THE CURRENT AND FAILURE MILEAGES WERE 145,000.

MY FUEL GAUGE IS NOT ACCURATE. WHEN THE VEHICLE IS FULL THE GAUGE READS EMPTY AND WHEN IT IS THE VEHICLE IS EMPTY THE FUEL GAUGE READS FULL AND SO ON. THE GAUGE IS VERY SPORADIC POINTING TO WHATEVER LEVEL OF FUEL IT WANTS TO, NEVER DISPLAYING THE TRUE AMOUNT OF FUEL IN THE FUEL TANK. I HAVE TO DEPEND ON MY ODOMETER TO READ THE FUEL TANK AMOUNT SOMEWHAT ACCURATELY; AT LEAST MUCH MORE ACCURATE THAN THE FUEL GAUGE WHICH IS TOTALLY INACCURATE ALL THE TIME. THIS IS A BIG PROBLEM AND FROM THE INFORMATION I HAVE RECEIVED, NOT AT ALL AN ISOLATED ONE. IT SEEMS THAT EVERY '99 CHEVY SILVERADO HAS THE SAME ISSUE. *TR

MANY COMPLAINTS WITH THIS VEHICLE MAY GET LONG BUT I AM NOT SURE AS WHERE TO SEND THEM ALL.#1 WINDOW REGULATOR FAILED THREE TIMES, THE FIRST TIME I HAD TO PAY THE FULL AMOUNT TO GET IT FIXED AS THE COMPANY RECOMMENDED BY THE DEALER WENT BANKRUPT BEFORE THE WARRANTY WAS UP, I WAS NEVER CONTACTED ABOUT THIS. #2 BROKE TWO MORE, TIMES DEALER PICKED UP COST ON THE SECOND TIME BUT NOT ON THE THIRD TIME THE WINDOW IS TAPED UP AS THE DEALER SAID THEY WON'T FIX IT AS THE 1 YEAR WARRANTY WAS UP. ANTI LOCK SENSOR WAS ONLY CLEANED AND IS STILL ACTING UP TRUCK LURCHES AFTER STOPS. DEALER SAID THAT THEY PROBABLY WON'T DO ANYTHING AS THEY ALREADY CLEANED THE SENSORS. THE TRUCK WAS PURCHASED USED AND I DID NOT NOTICE THE BED ON THE TRUCK HAD BEEN REPAIRED. IT LOOKS LIKE IT SITS A LITTLE LOWER NOW ON ONE SIDE THE SERVICE REP SAID THERE WERE SPOT WELDS WHERE THERE SHOULDN'T BE BUT WOULDN'T COMMENT BEYOND THAT. *TR

TWO YEARS AGO I RAN INTO THE BACK OF MY OWN SECOND VEHICLE, AS IT WAS PARKED IN MY DRIVEWAY, WHEN MY TRUCK WOULD NOT STOP AT SPEEDS LOWER THAN 10 MPH. I TOOK THE TRUCK INTO THE CHEVY DEALER AND THEY FIXED THE PROBLEM FOR FREE BECAUSE OF A RECALL. IT IS 2 YEARS LATER, AND THE TRUCK IS DOING THE SAME THING AGAIN. IT WILL NOT STOP AT LOW SPEEDS. I BROUGHT THE TRUCK BACK IN AND WAS TOLD THAT THE RECALL WOULD NOT COVER ANOTHER INSPECTION. I WAS ALSO TOLD THAT THE WHEEL BEARING SENSOR HAD BEEN CLEANED ACCORDING TO THE RECALL AND THAT IS WAS POSSIBLE CORROSION HAD BUILT UP AGAIN. I TOLD THE DEALER THAT IT WAS UNACCEPTABLE THAT EVERY 2 YEARS THE BREAKS JUST STOP WORKING.*CN

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.
