I HAD THE IGNITION SLEEVE REQUIRED IN RECALL DONE. NEVER HAD PROBLEMS WITH KEY BEFORE THAT. SINCE THEN, HAVE TROUBLE STARTING CAR; THE GARAGE REPLACED BATTERY (WAS 6 YRS. OLD) BECAUSE THEY COULD FIND NOTHING ELSE WRONG WITH THE CAR. STILL I HAVE DIFFICULTY STARTING THE CAR..........YESTERDAY IT TOOK 3 TRIES. I MOVED IN THE INTERIM OF HAVING THIS DONE....SO GOING BACK TO SIMON CHEVROLET IN WOONSOCKET,RI IS OUT OF THE QUESTION. I CALLED SALVATORE CHEVROLET IN GARDNER, MA. AND THEY TOLD ME THERE WOULD BE A $200. CHARGE TO FIND OUT WHAT THE PROBLEM WAS. NEVER HAD PROBLEMS BEFORE AND THIS SHOULD NOT BE A CHARGED FOR ISSUE. ANY SUGGESTIONS? ALSO, THIS MORNING THE DIAMOND SHAPED BUTTON FOR THE WARNING LIGHTS BROKE OFF AND FELL INTO DASH......THE CAR IS SOUND AND I KEEP IT WELL KEPT UP. THESE ARE JUST FRUSTRATING ISSUES. PLEASE ADVISE. THANK YOU FOR THE TIME AND EFFORT PUT INTO THIS MATTER. SINCERELY....[XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *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.
