SILVERADO 2500 HD V8 BRAKE & ROTOR REPLACEMENT 37,800 MILES WE PURCHASED A BRAND NEW 2002 CHEVROLET SILVERADO HD 4 X 4 FROM FITZGERALD AUTO MALL. THE TRUCK WAS PAMPERED, NO ROUGH OFF ROAD EXCURSIONS, EVEN KEPT IT IN THE GARAGE. WITH ONLY 37,800 MILES WE WERE LITERALLY SHOCKED TO DISCOVER ALL FOUR ROTORS NOT ONLY HAD SIGNIFICANT RUST BUT METAL WAS ACTUALLY CHIPPING, FLAKING, AND CRUMBLING FROM THE ROTORS. ALL FOUR ROTORS HAD TO BE REPLACED ALONG WITH THE BRAKE PADS. THE PADS HAD WORN BUT NOT [REPEAT NOT] DOWN TO THE "WEAR SENSORS" AND WERE REPLACED FOR SAFETY REASONS. THE COST FOR THE REPAIR WAS $1,150.00. WE HAVE OTHER VEHICLES "NONE OF THEM MANUFACTURED BY GM" AND NEVER EXPERIENCED THIS TYPE OF WEAR OR DAMAGE TO ROTORS. THE ONLY SAFETY RECALL WE WERE ADVISED OF AFFECTED THE TAILGATE CABLES. THE TAILGATE CABLES PREMATURELY CORRODED AND FAILED. THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION SHOULD BE ALERTED AS THIS POSES A SIGNIFICANT SAFETY RISK FOR ANYONE WHO UNWITTINGLY EXPERIENCES THIS PROBLEM. LEFT UNDETECTED THESE ROTORS WOULD HAVE FAILED CAUSING AN ABSOLUTE AND SUDDEN LOSS OF BRAKING CAPACITY. IF FORD MOTOR COMPANY HAD TO ACCEPT RESPONSIBILITY FOR RECALLING MILLIONS OF UNSAFE FIRESTONE TIRES - WHY HASN'T THIS PROBLEM BEEN ADDRESSED BY GM? *TR

TRUCK WAS TOWED TO DUNLAP-JOHNSON CHEVROLET CO.,INC. 919 E LIBERTY ST , YORK, SC 29745-2689 (803) 792-4152. CHEVROLET WAS CALLED AT 1-800-222-1020 AND CASE # 71-742-720900 WAS OPENED. I WAS CONTACTED ON JULY 21 BY CAROLINE LUCERO FROM CHEVROLET WHO STATED THAT THE BRAKE LINES FAILED BECAUSE OF ENVIRONMENTAL CONDITIONS IN THE NE UNITED STATES. HAVING BRAKE LINES THAT CAN FAIL WITHOUT WARNING CAUSING THE BRAKE PEDAL TO GO TO THE FLOORBOARD WHILE PROVIDING NO STOPPING EFFORT IS A VERY DANGEROUS SITUATION. THANKFULLY NO ONE WAS INJURED IN THIS INSTANCE; HOWEVER I SUSPECT THAT THE BRAKE LINE FAILURE IS PREMATURE BASED ON THE AGE AND MILEAGE OF THE VEHICLE AND POSSIBLY CAUSED BY DEFECTIVE MATERIALS. I AM SAVING THE BRAKE LINES IN CASE THEY ARE WANTED FOR TESTING OR INSPECTION. *TR

I OWN A 2002 CHEVROLET SILVERADO 2500 HD, 8.1 LITER, V8. IN THE PAST 4 MONTHS, THE VEHICLE COMPLETELY WOULD LOSE POWER AND SHUT OFF. AFTER A FEW MINUTES, THE VEHICLE WOULD RESTART. IT DID NOT MATTER THE SPEED OF THE VEHICLE, NOR DISTANCE DRIVEN. THERE WAS NO DASH BOARD LIGHTS ON INDICATING ANY PROBLEMS. I STALLED SEVERAL TIMES IN TRAFFIC, NEARLY MISSING/CAUSING ACCIDENTS. THE DEALER HAD VEHICLE FOR 3 DAYS AND SAID THERE WAS NOTHING ON DIAGNOSTIC SHOWING PROBLEMS. I REFUSED VEHICLE STATING I WAS NOT GOING TO ENDANGER MYSELF OR FAMILY TILL RESOLVED. IT WAS DETERMINED, AFTER THE GM BLOG AND PERSONAL INTERNET SEARCH OF THIS VEHICLE COMPLAINTS, THE CRANKSHAFT POSITION SENSOR WAS BAD. THE DEALER REPLACED FOR A CHARGE OF $288.38 PARTS/LABOR AT MY EXPENSE. THIS VEHICLE NEEDS A RECALL FOR THIS PART AND SOMEONE IS GOING TO BE SERIOUSLY HURT, ESPECIALLY WHEN THERE IS NO INDICATION OF A PROBLEM SHOWING.
