MY ISSUE WITH MY 2002 GMC SIERRA 1500 REGULAR CAB LONG BED IS RELATED TO AN ABS WHEEL SENSOR RECALL. I HAD MY TRUCK SERVICED IN DEC 2005 FOR THE RECALL PROBLEM. THE NATURE OF THE PROBLEM IS CORROSION AT THE ABS WHEEL SENSOR WHICH CAUSES THE ABS BRAKING SYSTEM TO ACTIVATE AT LOW SPEEDS WHEN STOPPING WHICH IN TURN INCREASES THE STOPPING DISTANCE. THIS IS A SAFETY ISSUE THAT CANNOT BE NEGLECTED. I HAD GONE TO THE BOB ROSS BUICK/GMC DEALERSHIP IN CENTERVILLE, OH ON 4/30/2009 ' ORIGINAL DEALER WHERE I PURCHASED THE TRUCK. THEY PERFORMED AN INSPECTION FOR $64.95 PLUS TAX AND 10% SHOP SUPPLIES CHARGE. THEY TOLD ME THAT SINCE THE TRUCK WAS ALREADY SERVICED FOR THE RECALL, THAT I AM NOT COVERED TO RE-REPAIR/REWORK THE TRUCK FOR THE RECURRENCE OF THE PROBLEM. I CONTACTED GM CUSTOMER CARE AND WORKED WITH A REPRESENTATIVE NAMED AL AND THEN AFTER HE SAID HE COULDN'T DO ANYTHING FOR ME FROM GM CORPORATE I WAS CONNECTED TO GM DISTRICT SPECIALIST DONALD HOWELL (1-800-790-5700 X41958). DONALD ALSO EVENTUALLY SAID THAT GM WOULD NOT HELP WITH GETTING THE WORK PERFORMED. THE SERVICE REQUEST # FOR MY CASE IS 71-758818423. MY REQUIREMENT FOR RESOLUTION IS THAT GM REPAIRS THE ISSUE AT NO COST TO ME, MOST PREFERABLY BY REPLACING THE ABS WHEEL SENSORS WITH NEW ONES LESS LIKELY TO CORRODE. I'M SURE THAT THE NEW PRODUCT DESIGN HAS THE CORROSION ISSUE IN MIND AND HAS FOUND A WAY TO AVOID IT. AS THE REPAIR HISTORY OF MY VEHICLE SHOULD STATE, THE ABS WHEEL SENSORS WERE CLEANED AND THEN SPRAY PAINTED WITH A 'CORROSION RESISTANT PAINT' TO FIX THE ISSUE IN DEC 2005. AS AN AUTOMOTIVE ENGINEER WHO WORKED FOR GM/DELPHI FOR 14 YEARS OF MY PROFESSIONAL CAREER, I KNOW THAT WHAT WAS PERFORMED PREVIOUSLY IS NOT A PERMANENT FIX. I ALSO AM WILLING TO BET THAT I AM NOT THE ONLY CUSTOMER WITH RECURRENCE OF THIS ISSUE. HAD IT BEEN FIXED CORRECTLY THE FIRST TIME ' WITH NEW ABS SENSORS - THEN THE PROBLEM WOULD NOT HAVE RECURRED. I SHOULD ALSO BE REIMBURSED FOR THE $76.46 I HAD TO SPEND FOR DIAGNOSIS. *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.
