IT STARTED WITH THE FUEL GAUGE FLUCTUATING BETWEEN FULL AND EMPTY WITH A FULL TANK OF GAS AND THE ABS AND BRAKE LIGHT ON DASH LIGHTING UP FOR APPARENTLY NO REASON. THEN IT STARTED GIVING ME TROUBLE STARTING AND MAKING A WEIRD WHINING NOISE. I CHECKED ALL THE FLUID LEVELS AND FUSES, EVERYTHING WAS OK. I WAS AT THE CAMP(MIDDLE OF NOWHERE) AT NIGHT WHEN I NOTICED THAT THERE WERE SPARKS COMING FROM AROUND THE AREA OF THE STARTER WHEN MY HUSBAND TRIED TO START IT.(IT JUST HAPPENED TO BE DARK AND I WAS SITTING WITH A VIEW OF THE RIGHT WHEEL WELL) I CHECKED THE WIRES AND FOUND WHAT MIGHT HAVE BEEN A BREAK IN THE INSULATION, TAPED IT AND THE SPARKS QUIT. HAD NO CHOICE BUT TO DRIVE IT HOME THE NEXT DAY AS THERE WAS NO PHONE SERVICE. STARTED RIGHT UP , AND DROVE FINE, EXCEPT FOR THE LOW WHINNY NOISE THAT NO ONE COULD PINPOINT. I WAS ALMOST HOME WHEN THE TRANSMISSION STARTED TO SLIP. I BROUGHT IT TO OUR MECHANIC WHO REPLACED THE TRANSMISSION BUT NONE OF US CAN FIGURE OUT WHAT THE DEVIL IS CAUSING THE ELECTRICAL PROBLEMS. BEFORE THE TRANSMISSION WENT OUT THE TOW/ HAUL BUTTON DIDN'T DO ANY THING, NOW THE LIGHT ACTUALLY COMES ON-WHEN IT FEELS LIKE IT,BUT I CAN'T GET IT TO GO OFF. THE GAS GAUGE IS STILL ACTING NUTS AND THE ABS AND BRAKE LIGHT STILL COME AND GO. PLEASE POST INSTRUCTIONS FOR TROUBLESHOOTING THIS THING! *TR

I BOUGHT A GMC SIERRA C-1500 PICKUP TRUCK, NEW IN 2001. IN SEPT '05, THE ABS LIGHT CAME ON & A HUMMING NOISE COULD BE HEARD EVEN AFTER THE IGNITION WAS TURNED OFF. THE ODOMETER WAS AT 50,000 MILES, AT THAT TIME. THE PROBLEM WAS THE EBCM SHORTED-OUT AND NEEDED TO BE REPLACED. NOW, 31,000 MILES & 3 YEARS LATER (81,000 TOTAL MILES), IT SHORTED-OUT AGAIN & NEEDED TO BE REPLACED. THE COST OF THIS PART ALONE IS $1,000.00 (+ OVER $200.00 INSTALLATION). THAT PART ISN'T EVEN SUBJECTED TO NORMAL 'WEAR & TEAR' LIKE BRAKES, BECAUSE IT'S NOT A MOVING PART. IT'S A COMPUTER MODULE THAT CONTROLS THE ANTI-LOCK BRAKES, THAT IS VITAL IN CASE OF EMERGENCY BRAKING, WHICH LUCKILY I HAVEN'T NEEDED TO USE. I DON'T KNOW IF THE EBCM (PART) IS DEFECTIVE ITSELF OR IF SOMETHING ELSE IS CAUSING IT TO SHORT OUT, BUT I DON'T THINK THIS PART SHOULD FAIL, THIS OFTEN. REQUIRING A THIRD EBCM IN 7 YEARS, IN MY OPINION, IS UNACCEPTABLE. I'VE CONTACTED GMC & I DON'T THINK I RECEIVED A LEGITIMATE REASON FOR THE FAILURE OF THE PART'JUST A POOR EXCUSE. HIS REASONING WAS THAT MY VEHICLE IS 7 YEARS OLD & HAS 81,000 MILES, THAT IT'S ACCEPTABLE FOR A COMPUTER MODULE, WHICH CONTROLS THE ANTI-LOCK BRAKES (A SAFETY ISSUE), TO MALFUNCTION & NEED REPLACING TWICE. THAT 'REASON' WAS TOTALLY ABSURD IN MY OPINION. MILEAGE SHOULDN'T COME INTO PLAY BECAUSE IT'S AN ELECTRONIC PART NOT A MOVING PART. IF THEY WANT TO JUSTIFY IT BECAUSE THE TRUCK IS 7 YEARS OLD'.IT WAS THE PART THAT FAILED, NOT THE TRUCK & IT WAS ONLY 3 YEARS OLD AND ONLY 31,000 MILES HAD BEEN ADDED, WHEN IT SHORTED-OUT AGAIN! SO, THEY SHOULDN'T EVEN BE TALKING ABOUT THE VEHICLE ITSELF'JUST THE FAULTY PART WHICH HAPPENS TO CONTROL A VERY IMPORTANT SAFETY FEATURE! *TR

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

ON CERTAIN VANS EQUIPPED WITH SURE-LOK WHEELCHAIR SECUREMENT SYSTEMS, THE SPROCKET TEETH OF THE RETRACTOR ASSEMBLY IS OUT OF ALIGNMENT.
Consequence & remedy
Consequence: IN THE EVENT OF A VEHICLE CRASH, THE WHEELCHAIR MAY NOT BE ADEQUATELY SECURED POSSIBLY RESULTING IN INJURIES TO A WHEELCHAIR OCCUPANT.
Remedy: DEALERS WILL INSPECT AND REPLACE THE WHEELCHAIR SECUREMENT RETRACTORS AS NECESSARY. SURE-LOK WILL HANDLE THE REPAIRS FOR THIS CAMPAIGN. OWNERS SHOULD CONTACT SURE-LOCK AT 1-908-231-1804 OR MOBILITYWORKS AT 1-800-769-8267.
VEHICLE DESCRIPTION: CERTAIN 2-WHEEL DRIVE PICKUP TRUCKS FAIL TO COMPLY WITH REQUIREMENTS OF FMVSS NO. 120, "TIRE SELECTION AND RIMS FOR MOTOR VEHICLES OTHER THAN PASSENGER CARS." THE PROBLEM WAS CAUSED BY A COMPUTER ERROR THAT RESULTED IN THE CERTIFICATION LABEL LISTING TIRE SIZE AND INFLATION PRESSURE INFORMATION THAT DIFFER FROM THE TIRE SIZE AND THE INFLATION PRESSURE INFORMATION FOR THE TIRES ON THE VEHICLE. IF THE VEHICLE OWNER OR SOMEONE SERVICING THE VEHICLE INFLATES THE TIRES ACCORDING TO THE PRESSURE SPECIFIED ON THE LABEL VERSUS THE APPROPRIATE PRESSURE FOR THE TIRES, THE TIRES COULD BE UNDER-INFLATED OR OVER-INFLATED DEPENDING ON THE TIRES MOUNTED ON THE VEHICLE.
Consequence & remedy
Consequence: IF THE TIRES ARE UNDER-INFLATED, IT COULD REDUCE THE TREAD LIFE OF THE TIRE, AND THE TIRE COULD DEGRADE TO A POINT OF ALLOWING SUDDEN AIR LOSS. IF THE TIRES ARE OVER-INFLATED, IT COULD REDUCE THE TREAD LIFE OF THE TIRE AND INCREASE SUSCEPTIBILITY TO ROAD HAZARD DAMAGE. IF SUDDEN AIR LOSS OR A ROAD HAZARD CAUSES DAMAGE TO A TIRE, CONTROL OF THE VEHICLE COULD BE ADVERSELY AFFECTED AND COULD RESULT IN A VEHICLE CRASH.
Remedy: OWNERS WILL BE PROVIDED WITH A NEW LABEL AND INSTALLATION INSTRUCTIONS. HOWEVER, A DEALER CAN INSTALL THE LABEL IF THE OWNER SO DESIRES. OWNER NOTIFICATION BEGAN MAY 31, 2001. OWNERS WHO DO NOT RECEIVE THE LABEL AND INSTALLATION INSTRUCTIONS WITHIN A REASONABLE TIME SHOULD CONTACT CHEVROLET AT 1-800-222-1020 OR GMC AT 1-800-462-8782.

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.
