I'M AFRAID THAT THE FRAME IS GOING TO BRAKE WHILE I AM DRIVING DOWN THE ROAD WITH MY KIDS IN THE TRUCK AND GET IN A BAD ACCIDENT. I CONTACTED CHEVY AND THEY WILL DO NOTHING FOR ME.

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.

I AM SUBMITTING THIS COMPLAINT BECAUSE GM HAS NOT REIMBURSED ME FOR A RECALL IN WHICH I PAID FOR OUT OF MY OWN POCKET. THE REIMBURSEMENT AMOUNT IS MINUSCULE AND WOULD HAVE BEEN FAR LESS THAN WHAT THE DEALERSHIP WOULD HAVE CHARGED BACK TO GM. PLEASE SEE THE DETAIL TO THIS COMPLAINT BELOW. APRIL 2006 I RECEIVED A RECALL NOTICE FROM GM, IT STATED THE FOLLOWING: 1. YOUR 1999 MODEL YEAR CHEVROLET SILVERADO, IS INVOLVED IN A SAFETY RECALL 06019. 2. SCHEDULE AN APPOINTMENT WITH YOUR CHEVROLET DEALER. 3. THIS SERVICE WILL BE PERFORMED FOR YOU AT NO CHARGE. I DO NOT RECALL THE SPECIFIC DATES BUT I SCHEDULED AN APPOINTMENT WITH MY LOCAL DEALER WILSON CHEVROLET, STILLWATER OK, I CALLED AND MADE THE APPOINTMENT ON MONDAY AND SCHEDULED THE APPOINTMENT FOR THAT WEDNESDAY. THAT WEDNESDAY I ARRIVED AT 8:00 AM ON TIME AT WILSON CHEVROLET. I SPOKE WITH THE SERVICE GENTLEMEN AT THE DESK AND HE PROCEEDED TO TELL ME THAT I HAD HAVE TO LEAVE MY VEHICLE. THEY DID NOT OFFER TO GIVE ME A RIDE TO WORK OR ANYTHING, SIMPLY STATING I COULD RESCHEDULE. RESCHEDULE WAS OUT OF THE QUESTION DUE TO I HAD ALREADY TAKEN A LEAVE OF ABSENCE FROM WORK AND THE DEALERSHIP WAS ON THE OPPOSITE SIDE OF TOWN; IT WAS A 30 MINUTE DRIVE ROUND TRIP FROM MY PLACE OF EMPLOYMENT. CONSIDERING MY OPTIONS I REMEMBERED THAT IN THE MAILING GM HAD PROVIDED A REIMBURSEMENT FORM. I OPT TO PURCHASE THE CABLES FROM THE DEALER AND REPLACE THEM MYSELF AND FILE A REIMBURSEMENT WITH GM. I ISSUED A REIMBURSEMENT TO GM USING THEIR FORM, I ASKED FOR A REIMBURSEMENT OF $44.44, THE COST OF THE CABLES INCLUDING TAX. ON OCTOBER 16, 2006, A FEW MONTHS LATER AFTER SUBMITTING THE REIMBURSEMENT REQUEST I RECEIVED A DENIAL LETTER DENYING REIMBURSEMENT, NO REASON WAS GIVEN. I ASK NTHSA TO LOOK INTO THESE CLAIMS AS I AM NOT AWARE OF MY RIGHTS TO SEEK REIMBURSEMENT ON A RECALL THAT GM IS RESPONSIBLE FOR. *JB

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.
