I AM THE ORIGINAL OWNER OF A 2002 CHEVROLET SILVERADO 2500HD PICKUP TRUCK. ON 12/11/09 WHILE DRIVING THE TRUCK, I APPLIED THE BRAKES AND THE PEDAL WENT COMPLETELY TO THE FLOOR, LEAVING ME WITH NO BRAKES. FORTUNATELY, I WAS GOING VERY SLOW AT THE TIME AND WAS ABLE TO ROLL TO A SLOW STOP WITH NO DAMAGE OR INJURY. I FOUND THAT MY BRAKE LINES WERE RUSTY WITH A HOLE ENTIRELY THROUGH ONE PLACE. I DID AN INTERNET SEARCH ON 'SILVERADO" AND 'RUSTY BRAKE LINES' AND FOUND NUMEROUS OTHER IRATE OWNERS WITH THE SAME PROBLEM. I CONTACTED GENERAL MOTORS AND WAS TOLD I WOULD NEED TO HAVE A DEALER INSPECT THE TRUCK BEFORE ANY ADDITIONAL ACTION COULD BE TAKEN. THIS IS THE RESULT: I WAS CHARGED $175.09 FOR HAULING THE VEHICLE 20 MILES TO THE NEAREST DEALER AND 'INSPECTING IT; YES, THE LINES WERE RUSTED OUT AS I HAD TOLD THEM; GENERAL MOTORS WILL PROVIDE NO FURTHER ACTION BECAUSE THE PROBLEM MAY BE THE RESULT OF 'LOW MILEAGE'; AND THE DEALER WANTS TO REPLACE THE BRAKE LINES FOR $1000.00. I LIVE IN NORTH CAROLINA AND HAVE DRIVEN AND WORKED ON VEHICLES FOR OVER 50 YEARS AND I HAVE NEVER BEFORE HAD A HOLE RUSTED IN A BRAKE LINE. THE SUDDEN AND UNEXPECTED LOSS OF BRAKES HAS TO BE A DEADLY DISASTER WAITING TO HAPPEN. *TR

MY 2002 CHEVROLET SILVERADO 2500 HD WAS HAVING A PROBLEM WITH THE ABS SYSTEM ACTIVATING AT SLOW SPEEDS WHEN THE WHEELS WERE NOT ACTUALLY SLIDING. ALTHOUGH THE WHEELS WERE ACTING EXACTLY AS DESCRIBED IN RECALL BULLETIN 05068C, I WAS TOLD BY THE DEALER THAT MY TRUCK WAS NOT COVERED EVEN IF THE PROBLEM WAS DUE TO FRONT WHEEL SPEED SENSOR CORROSION AS DESCRIBED IN THE RECALL. I ALSO CALLED THE GM CUSTOMER ASSISTANCE CENTER AT 800-630-2438 WHERE THEY ALSO SAID MY TRUCK IS NOT COVERED EVEN THOUGH THE VIN IS WITHIN THE BRACKETS IN THE RECALL. I WAS GIVEN A CASE NUMBER OF 71-774131746. I TOOK MY TRUCK TO LARSON CHEVROLET IN SUPERIOR, WI ON NOVEMBER 10, 2009 WHERE THEY INSPECTED MY FRONT WHEELS AND FOUND THE CORROSION DESCRIBED IN THE RECALL. I HAD THEM REPAIR THE CORROSION AT MY EXPENSE. I THEN CONTACTED CUSTOMER ASSISTANCE AGAIN AND THEY AGREED TO FORWARD MY CASE TO A DISTRICT SPECIALIST. AFTER A COUPLE CONVERSATIONS WITH THE DISTRICT SPECIALIST ISAAC I WAS TOLD THAT MY TRUCK WOULD NOT BE COVERED BECAUSE 3/4 TON TRUCKS WERE EXCLUDED. NO REASON FOR EXCLUDING 3/4 TON TRUCKS WAS GIVEN. IT SEEMS TO ME THAT GM WAS IN ERROR WHEN 3/4 TON TRUCKS WERE EXCLUDED BECAUSE MY TRUCK HAD THE EXACT PROBLEM DESCRIBED IN THE RECALL. I WOULD LIKE TO SEE THE RECALL EXPANDED TO INCLUDE 3/4 TON TRUCKS AND TO HAVE MY EXPENSES OF $206.47 REIMBURSED. *TR

UPON INSPECTION OF THE REST OF THE LINES I FOUND THEM ALL TO BE RUSTED TO THE POINT THAT I WILL BE REPLACING ALL OF THE LINES ON THE TRUCK. *TR

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

2002 CHEVROLET 2500HD PICKUP TRUCK. WHILE MY DAUGHTER WAS DRIVING THE TRUCK, BOTH STEEL BRAKE LINES FROM THE MASTER CYLINDER FAILED CAUSING TOTAL LOSS OF BRAKES. 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
