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

FOR SEVERAL MONTHS I HAD NOTICED THAT THE ABS WOULD OCCASIONALLY ENGAGE AT LOW SPEEDS ON DRY PAVEMENT, RESULTING IN INCREASED PEDAL TRAVEL AND INCREASED STOPPING DISTANCES. THEN ON DECEMBER 15, AS I LEFT THE HOUSE AND HAD DRIVEN ABOUT 100 YARDS, I HEARD A GRINDING SOUND COMING FROM THE ABS UNIT NEXT TO THE TRANSFER CASE, AND THE NOISE STOPPED WHEN I PULLED THE ABS FUSE. I CALLED O'BRIEN CHEVROLET, AND THE EARLIEST THEY COULD LOOK AT IT WAS DECEMBER 20. THEY LOOKED AT IT, AND TOLD ME THAT THE ABS UNIT HAD DEVELOPED AN INTERNAL SHORT, AND WOULD HAVE TO BE REPLACED, COSTING ABOUT $1200.00. I WAS SHOCKED! THIS TRUCK IS IN LIKE-NEW CONDITION, WITH ONLY 37,200 MILES, AND ITS ALWAYS BEEN KEPT IN A GARAGE OR A CARPORT. I CAN'T BELIEVE THAT 37,200 MILES IS A NORMAL SERVICE LIFE OF A GENERAL MOTORS ABS UNIT BEFORE THEY DEVELOP SHORTS AND HAVE TO BE REPLACED. *JB

LAST FALL I REPORTED TO NHTSA THAT A SOLID BRAKE LINE TUBING FAILED ON MY 1999 SILVERADO WHICH I LOST BRAKING POWER WHICH ALMOST CAUSED ME TO GO OVER THE SIDE OF THE MOUNTAIN JUST BEFORE KINGWOO WV. I HAD THIS REPAIR DONE A THE CHEVY DEALER IN NEARBY OAKLAND MD NAMED TEAM ONE. NO RESPONSE WAS RECEIVED FROM NHTSA. WEDNESDAY THIS PAST WEEK I WAS HEADING FOR CLARKSBURG VAMC WHEN THE SECOND RIDGED BRAKE LINE CRACKED AS THE FIRST. AGAIN I ALMOST LOST THE VEHICLE AS I WAS GONG DOWN HILL JUST OUTSIDE KINGWOOD AND ALMOST LOST THE TRUCK OVER THE MOUNTAIN. AGAIN I GOT IT THIS TIME TO JOE ROMEOS CHEVY DEALER WHERE I PURCHASED THE TRUCK. SAME FINDINGS AS THE FIRST AND THEY REITERATED THAT THIS WAS NORMAL WEAR AND TEAR AND MY EXTENDED WARRANTY WOULD NOT COVER IT, BUT I STATED HOW CAN LINES THAT SHOULD HAVE BEEN STAINLESS STEEL OR RUST RESISTANT THAT FAIL BE EXCLUDED FROM THE WARRANTY? I ASKED THIS OF GM LAST WEEK AND ALL I GOT WAS A BEAT AROUND THE BUSH ANSWER AND THEY WOULD NOT PAY. THIS LEAVES ME WITH OVER $400 IN REPAIR BILLS I HAVE TO PAY. MY TRUCK HAS BEEN AT THE LATEST DEALER FOR ALMOST A WEEK NOW WITH HOPES OF GETTING IT BACK TODAY. THIS WHAT I CALL INFERIOR PARTS BUT MY ELECTRIC WHEEL CHAIR THAT IS IN BACK OF THE VEHICLE I DO HAVE USE OF. [XXX],OF CRL AND ASSOC MOTORCYCLE SAFETY CONSULTANT. ALSO I MENTIONED THE DEALER HAS KNOWLEDGE OF OTHERS THAT THEY BROKE IN SAME MANOR AS MINE. *JB 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.
