I OBSERVED CRACKS IN MY TIRES ABOUT 1 INCH OUT FROM THE RIM. ALL FOUR TIRES ARE STARTING TO CRACK OUT ALONG THE BEAD LINE IN A CIRCLE AROUND THE TIRE. THE DEALER I PURCHASED THESE FROM SAYS IT IS NOT DANGEROUS, BUT HE IS WILLING TO CREDIT A SMALL SUM TOWARDS A NEW SET OF TIRES. WHY WOULD SOMEONE CREDIT YOU IF THE TIRES ARE NOT DEFECTIVE. IT APPEARS THEY ARE TRYING TO COVER THIS UP. MY FAMILY RIDES IN THIS VEHICLE AND NOW I AM CONCERNED FOR THEIR SAFETY. THE DEALER WANTS TO SELL ME A SET OF TIRES JUST LIKE I HAVE AND WILL ONLY CREDIT ME IF I PURCHASE FROM HIM OR HOLT THE TIRES AND CREDIT TILL I NEED A NEW SET. I HOPE TO HEAR FROM YOU QUICKLY BECAUSE I NEED MY TRUCK. THE TIRES ARE MASTERCRAFT COURSER AT-2 265-75R16 PURCHASED ON 5/26/07. *TR

THE INTERMEDIATE STEERING SHAFT WENT BAD ON IT I HAD A MECHANIC LOOK OVER THE TRUCKS FRONT END THINKING THE BALL JOINTS WERE BAD. THAT WASN'T THE CASE HIS DAD HAS AN 04 SILVERADO THAT HAD THE SAME PROBLEM. I CALLED MY LOCAL CHEVROLET GARAGE IN INDIANA AND THEY ACTED LIKE THEY NEVER HEARD OF IT. SO I CALLED THE LOCAL GMC DEALERSHIP AND ITS GETTING FIXED NEXT WEEK. SENSE ITS A 2002 THERE IS NO WARRANTY SO ITS GOING TO COST AROUND 200 DOLLARS. IT MAKES A CLUNKING NOISE IN THE FRONT END AND THE STEERING WHEEL FEELS LOOSE. IT ALSO MAKES A WEIRD GRINDING NOISE SO I HOPE THIS FIXES MY PROBLEM!!! *TR

I HAVE A 2002 CHEVY SILVERADO THAT WAS PART OF A RECALL FOR ANTI-LOCK BRAKES ENGAGING AT LOW SPEEDS (4-10MPH). I TOOK MY TRUCK TO A DEALERSHIP TO HAVE THE RECALL SERVICE PERFORMED IN 2006. NOW, IN 2008, AS I WAS DRIVING THROUGH TOWN, MY ANTI-LOCK BRAKES KICKED IN AND I ALMOST WRECKED INTO THE CAR IN FRONT OF ME. IT NOW HAPPENS ON A REGULAR BASIS EVERYTIME I TRY TO BRAKE AT LOW SPEEDS. I CALLED CHEVY TECHNICAL SUPPORT AND THEY WERE OF NO HELP WHATSOEVER. THEY COULD NOT OFFER A GOOD EXPLANATION AS TO WHY THEY WOULD NOT FIX MY PROBLEM, EVEN THOUGH THEY ACKNOWLEDGE IT IS A PROBLEM AND A SAFETY HAZARD. *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.
