2000 Chevrolet Silverado complaints

I AM WRITING TO PROTEST THE RECENT DECISION BY CHEVROLET TO NOT ASSIST ME IN THE REPAIRING OF MY TRUCK DUE TO WHAT I FEEL IS A MANUFACTURER'S DEFECT. I OWN A 2000 CHEVROLET SILVERADO. I WENT TO GET MY FIRST INSPECTION STICKER BECAUSE THE MANUFACTURERS TWO-YEAR INSPECTION STICKER WAS OUT OF DATE. THE TRUCK FAILED INSPECTION BECAUSE THE REAR PARKING BRAKE SHOES WERE WORN AND THE PARKING BRAKE WOULD NOT WORK. I WAS PUZZLED HOW THIS COULD BE WHEN I HAVE NEVER USED MY PARKING BRAKE. I LIVE IN TEXAS AND HAVE NOT HAD A REASON TO USE IT. MY MECHANIC TOLD ME THAT THE PARKING BRAKE SHOES WERE WORN BECAUSE THE CLIPS THAT HOLDS THEM IN PLACE HAD FAILED. HE ALSO INFORMED ME THAT THERE WAS A TECHNICAL BULLETIN (REFERENCE NUMBER 02-05-26-002 & 02-05-26-001) ABOUT THIS PARKING BRAKE ISSUE AND ADVISED ME TO CALL CHEVROLET. I DID. I WORKED WITH GREG SYNDER AT CHEVROLETS CUSTOMER SUPPORT AND MY SERVICE REQUEST NUMBER WAS 1-126-315-169. I, FROM THE START, VIEWED THIS AS A MANUFACTURERS DEFECT. IN SHORT, CHEVROLET WOULD NOT FIX OR ASSIST IN THE COST OF THE REPAIRS BECAUSE THEY FELT THAT THIS WAS NORMAL WEAR AND TEAR. ALSO THEY NOTED THAT MY TRUCK WAS OUT OF THE MANUFACTURER'S WARRANTY (3 YEARS/36000 MILES). I TOTALLY DISAGREE WITH THE DECISION. FIRST, HOW CAN THIS BE NORMAL WEAR AND TEAR IF THE PARKING BRAKE HAS NEVER BEEN USED? ALSO, WHO REPLACES THEIR PARKING BRAKE SHOES ON A VEHICLE THAT IS 3 YEARS OLD AND THE PARKING BRAKE AGAIN HAS NEVER BEEN USED? EVEN IF IT HAS BEEN USED, THE PARKING BR

THE CONSUMER STATED THAT PARKING BRAKE DID NOT LOCK. THE DEALER WAS NOTIFIED. *AK THERE WAS PREMATURE WEAR OF THE PARKING BRAKE. (AS IDENTIFIED IN THE TSB) DUE TO THE DESIGN OF THE LOW EFFORT PEDAL, THE CONSUMER DID NOT RECOGNIZE WHEN THE BRAKE HAD BECOME DEFECTIVE AND UNABLE TO HOLD. THE WEAR OCCURRED WHEN THE BRAKES WERE NOT USED. THE REDESIGNED CLIP MAY OR MAY NOT PREVENT THE PREMATURE WEAR. *SCC

PROBLEMS WITH 2000 CHEVROLET SILVERADO ROTORS, WHEELS, TAILGATE STRAP, DRIVE SHAFT, AND 4-WHEEL DRIVE.*MR NAR SEE ODI#10037613 ES03-006296. AT 12000 MILES BOTH REAR ROTORS HAD TO BE REPLACED, 2000 MILES LATER BOTH FRONT ROTORS HAD TO BE REPLACED. A CLUNKING SOUND WAS HEARD IN THE REAR OF THE VEHICLE. THE CONSUMER BELIEVES IT EITHER THE REAR SUSPENSION OR DRIVE SHAFT. ALL FOUR OF THE VEHICLE'S WHEELS HAD TO BE REPLACED AT 6000 MILES BECAUSE THEY WERE RUSTING. THE TAILGATE STRAP BROKE AT 17000 MILES. WHEN THE FOUR WHEEL DRIVE WAS ENGAGED THERE WAS A GROWLING NOISE. *NM

ABS LIGHT ILLUMINATED. VEHICLE WAS TAKEN TO THE DEALER WHICH STATED THAT VEHICLE NEEDED A NEW ABS VALVE AND MODULE. *AK *TS

THE ANTI-LOCK BRAKING SYSTEM ON THE CHEVROLET SILVERADO IS TOO SENSITIVE. I HAVE HAD SEVERAL INCIDENTS WHERE THE SYSTEM ACTIVATED WHEN IT SHOULD NOT HAVE CAUSING THE VEHICLE TO EXPERIENCE INCREASED STOPPING DISTANCES.I CONSIDER THIS TO BE A MAJOR SAFETY PROBLEM.I FILED A COMPLAINT WITH YOUR OFFICE SEVERAL YEARS AGO,BUT HAVE YET TO SEE ANY ACTION TAKEN TO CORRECT THIS PROBLEM

CONSUMER CALLED COMPLAINING ABOUT HAVING THROTTLE PROBLEMS. WHILE DRIVING THROTTLE WILL STICK TO THE FLOOR. IT DOESN'T HAPPENED ALL THE TIME, BUT HE IS AFRAID THAT MAY CAUSE HIM TO GET INTO AN ACCIDENT. MANUFACTURER5 WAS NOT DCONTACTED. DEALER WAS CONTACTED, AND STATED THAT GMC HA ADDRESSED THE ISSUE. BUT IT WOULD COST THE CONSUMER IF IT WAS NOT BROKEN, AND THE WARRANTY WILL NOT REPLACE IT UNLESS BROKEN.*AK

I HAVE HAD A PROBLEM WITH THE ROTORS ON MY 2000 CHEVROLET TRUCK. AFTER 18,600 MILES ALL FOUR ROTORS HAVE STATED TO FALL APART. THE SURFACE WERE THE PAD CONTACT HAVE GREAT AMOUNT OF CORROSION AND THE ROTOR MATERIAL FLAKED OFF. SOME HAD VOIDS ABOUT TWO INCHES IN DIAMETER AND DEEP ENOUGH THAT THE PADS NO LONGER MADE CONTACT WITH THE SURFACE OF THE ROTOR. THE MATERIAL THAT RUSTED OFF GOT IMBEDDED INTO THE PADS SO THEY WERE LESS EFFECTIVE ON THE REMAINING SURFACE MATERIAL OF THE ROTOR. I FOUND OUT ABOUT THE PROBLEM WHEN THE TRUCK DID NOT WANT TO STOP PROPERLY. I HAD MY LOCAL GARAGE CHECK THE BRAKES AND THEY INFORMED ME ABOUT THE ROTORS. THEY REBUILT THE REAR BRAKES. I THEN TOOK THE TRUCK TO THE LOCAL CHEVY GARAGE AND THEY REPLACED THE FRONT AT NO COST.*AK

VEHICLE WOULD NOT STOP DURING EMERGENCY SITUATIONS. MANY TIMES I SLAMMED ON THE BRAKES AND THE TRUCK WILL STOP AT FIRST A SECOND AND THEN THE BRAKES WOULD LET GO AND THE TRUCK WOULD STILL GO. I HAVE TO PUT THE BRAKES TO THE FLOOR AND THEN THE TRUCK WOULD SLOW DOWN. I HAVE TAKEN THE TRUCK TO 3 DIFFERENT DEALERS IN SAN DIEGO AND NONE OF THEM KNEW THE PROBLEM. ONE DEALER TOLD ME TO GENTLY APPLY THE BRAKES FOR THE VEHICLE TO STOP PROPERLY, BUT I'M SORRY, I CAN'T DO THAT DURING A PANIC SITUATION. THE HAS FAILED AT LEAST 5 TIMES AND ONE TIME WHEN MY PREGNANT SISTER WAS DRIVING, THE TRUCK WOULD NOT STOP THROUGH A PARKING LOT, SO SHE CRASHED INTO ANOTHER VEHICLE. DON'T KNOW WHAT DO NOW. TRUCK IS ALREADY OVER EXTENDED WARRANTY. WE PLAN ON SELLING THE TRUCK SOON AND BUYING ANOTHER BECAUSE THIS ONE IS NOT SAFE. *AK

WHILE DRIVING AT 45MPH CONSUMER HAD A FRONT COLLISION ,AND NEITHER OF THE FRONT BAGS DEPLOYED. *AK

PROBLEM WITH CHEVROLET SILVERADO PARKING BRAKES. THEY FAIL CONSTENTLY...ITS A SAFETY HAZARD WHEN PULLING A BOAT OR PARKING ON A HILL, ESPECIALLY WITH A MANUAL TRANSMISSION. IT IS USUALLY 200-300 DOLLARS TO REPAIR. I HAD MY TRUCK ROLL BACK WHILE TRYING TO LOAD A BOAT. I FEEL THIS IS A PROBLEM THAT CHEVROLET WILL NOT OWN UP TOO. LUCKLIY NO ONE WAS INJURED. I HAVE LOOKED ONLINE AT SEVERAL MESSAGE BOARDS AND IT SEEMS TO BE A WIDESPREAD PROBLEM. THANKS DANIEL. *AK

POWER ASSIST WENT OUT ON STEERING AND BRAKES. *AK

THE HYDRAULIC PUMP WAS INOPERATIVE. WHILE BACKING THE VEHICLE OUT OF DRIVEWAY, THE HYDRAULIC PUMP FAILED TO WORK. MANUFACTURER WAS CONTACTED, AND STATED THEY WOULD LOOK AT IT. BUT CONSUMER HAD NOT HEARD ANYTHING ABOUT IT. *AK THE HYDRAULIC PUMP SHAFT SEVERED WHILE THE CONSUMER WAS DRIVING. THE VEHICLE HAD BECOME IMPOSSIBLE TO STEER . THE MECHANIC STATED THIS WASN'T THE FIRST INCIDENT WITH THIS MAKE/MODEL. *SCC *JB

WHILE DRIVING THE POWER STEERING FLUID LEAKED WHICH MADE THE VEHICLE DIFFICULT TO STEER. THE BRAKE PEDAL ALSO WENT TO THE FLOOR AND THE BRAKES DID NOT RESPOND. THE CONSUMER BELIEVES THE POWER STEERING FAILURE CAUSED THE BRAKES TO FAIL. *AK *CB *NLM

MY BRAKES FAILED AFTER ACCELERATING FROM BEING STOPPED AT A RED LIGHT. THE LIGHT TURNED YELLOW BEFORE WE WERE INTO THE INTERSECTION WHEN THE VEHICLE IN FRONT OF ME STOPPED, SPEED WAS LESS THAN 10 MPH. I ATTEMPTED TO STOP ON A BUMPY DRY SURFACE WHILE BRAKING THE PEDAL WENT TO THE FLOOR AND HIT THE VEHICLE IN FRONT OF ME. DEALERSHIP CLAIMS BRAKES WERE WITHIN SPECIFICATIONS SET BY MANUFACTURE. SOMETHING NEEDS TO BE DONE ABOUT THIS PROBLEM, THERE ARE TOO MANY COMPLAINTS DEALING WITH THE ABS SYSTEM ON THE SILVERADO. PLEASE DO SOMETHING TO CORRECT THIS PROBLEM. *NLM

HAD TO HAVE BRAKES REPLACED ON 2000 CHEVY SILVERADO. ROTORS WERE RUSTED OUT. HAVE NEVER HAD ROTORS RUST OUT ON A VEHICLE. VEHICLE HAD ONLY APPROX. 35,000 MILES ON IT. COST ME FOUR TIMES AS MUCH AS I EXPECTED FOR THE BRAKE JOB. *JB

PARKING BRAKE (EMERGENCY BRAKE) ON MY 2000 CHEVROLET SILVERADO WILL NOT HOLD THE VEHICLE. HAVE DISCOVERED THROUGH INTERNET WEB SITES THAT IT IS NOT JUST MY VEHICLE, BUT THOUSANDS HAVE THE EXACT PROBLEM. DISCUSSED WITH THE LOCAL CHEVROLET DEALER AND WAS TOLD THAT GM IS AWARE OF THE POOR/FAULTY DESIGN BUT WILL NOT ADDRESS THE PROBLEM UNLESS, OF COURSE, I WANT TO PAY TO HAVE IT FIXED. DO NOT FEEL I SHOULD HAVE TO PAY FOR THEIR MISTAKE. THIS IS A SEVERE SAFETY PROBLEM BY IT NOT BEING ABLE TO HOLD THE VEHICLE. FEEL NHTSA SHOULD FORCE GM TO INSPECT AND FIX ANY THAT HAVE A PROBLEM BEFORE THEY END UP GETTING SUED BECAUSE SOMEONE'S CHILD GOT RUN OVER BY A ROLLING VEHICLE. SHOULD NOT HAVE TO WAIT FOR DEATHS OR INJURIES TO OCCUR BEFORE SOMETHING IS DONE ABOUT IT!*JB

2000 CHEVROLET SILVERADO MY HUSBAND HAD AN ACCIDENT FRONTAL SIDE IMPACT. THE ENGINE STARTED ON FIRE AFTER IMPACT. *NLM

THE ACCELERATOR PEDAL BECAME STUCK WHEN IT WAS APPLIED. *JB

THE VEHICLE AUTOMATICALLY SHIFTED INTO 4-WHEEL DRIVE. PH

WHILE DRIVING THE CONSUMER APPLIED THE BRAKES AND THEY FAILED COMPLETELY WITHOUT WARNING. THE DEALER DIAGNOSED THAT ALL ROTORS WERE CHIPPED OFF AND COMPLETELY RUSTED THROUGH. *NLM

WHILE TRAVELING TO WORK ON A ICY ROAD, MY ACCELERATOR STUCK AND I COULDN'T ACCELERATE. IT THEN RELEASED ALL THE WAY TO THE FLOOR BOARD WHERE IT STUCK AGAIN. I LOST CONTROL OF THE PICKUP AND SLID INTO ON COMING TRAFFIC WHERE I HAD A HEAD ON COLLISION. THE ACCELERATOR STICKING WAS THE CAUSE OF THE WRECK AND I BELIEVE THAT CHEVY IS WELL AWARE OF THE PROBLEM. SOMETHING MUST BE DONE BEFORE IT HAPPENS AGAIN. *JB

WHILE DRIVING THE VEHICLE AT NORMAL SPEEDS THE REAR DRIVE TRAIN BROKE (REAR AXLE). *NLM

MY TRUCK JUST STOPPED RUNNING, IT STARTED RIGHT BACK UP, BUT WHAT HAPPENED??? NOW AT TIMES IT TURNS OVER ALOT BEFORE IT STARTS AND IT ROUGH IDLES! WHAT IS THE PROBLEM??? I HAVE HEARD THAT IT IS PROBABLY A FUEL REGULATOR--VERY EXPENSIVE REPAIR ON ALOT OF SILVERADOS-- I THINK GM SHOULD REPLACE THESE FOR FREE BECAUSE THERE IS ALOT OF THESE WITH THIS SAME PROBLEM. *NLM

THE ACCELERATOR PEDAL BECAME STUCK. *JB

THE ANTI-LOCK BRAKES ACTIVATED AT VERY LOW SPEEDS. THE PEDAL MOVED UPWARD AND DRIVER PUSHED THE BRAKE PEDAL WITH FORCE BUT THE BRAKES DID NOT RESPOND. *NLM THE LEFT FRONT BRAKES FAILED 100% OF THE TIME AND THE RIGHT FRONT ASSEMBLY FAILED INTERMITTENTLY. BOTH FRONT WHEEL BEARING ASSEMBLY/SENSORS WERE REPLACED. THE BRAKE PEDAL HAD BECOME HARD AS A ROCK AND WOULD NOT STOP UNTIL BOTH FEET WERE PUSHED WITH MAXIMUM FORCE. *SCC

WHEN THE BRAKES WERE APPLIED, THE VEHICLE VIBRATED. IT WAS DISCOVERED THE ROTORS WERE WORN. *JB

SINCE PURCHASING THE 2000 SILVERADO Z71 LS K1500 TRUCK I HAD THE PARKING BRAKE SERVICED TWO SEPARATE TIMES. THE FIRST TIME AT 29,987 MILES, THE PARKING BRAKE DID NOT WORK. IT REQUIRED "ADJUSTMENT" AND I WAS CHARGED $112.50. I WAS SURPRISED THE PARKING BRAKE REQUIRED ADJUSTMENT SINCE IT IS NOT USED TO STOP THE VEHICLE, BUT RATHER USED TO KEEP IN PLACE WHEN PARKED AND IT WAS RARELY USED SINCE WE LIVE ON FLAT TERRAIN. I WAS FURTHER SURPRISED TO SEE THAT THIS WAS NOT COVERED UNDER WARRANTY BUT I LET THIS GO SINCE I WAS TOLD IT WAS A WEARABLE PART. I DID NOT SEE THE ACTUAL PARKING BRAKE PADS BUT WAS CONCERNED THAT I WAS NOT ABLE TO ADJUST THEM AND HEY REQUIRED ADJUSTMENT AFTER SUCH SHORT OF MILEAGE. AGAIN AT 66,023 MILES, THE PARKING BRAKE CEASED WORKING FOR THE SECOND TIME. THIS IS JUST 36,036 MILES AFTER THEY WERE ADJUSTED. AFTER LOOKING AT THE ORIGINAL PARKING BRAKE PADS, THE FRONT TOP OF THE PAD WAS WORN ALMOST COMPLETELY AWAY WHILE THE BACK PAD WAS WORN VERY LITTLE. THIS COST ME AN ADDITIONAL $228.84 TO HAVE THE PADS REPLACED AS THEY COULD NO LONGER BE ADJUSTED. I DID NOTICE THE NEW PADS WERE OF A DIFFERENT DESIGN WITH A LARGER CLIP THAT HOLDS THEM IN PLACE, APPLYING MORE PRESSURE OVER A LARGER AREA. ACCORDING TO THE TECHNICIAN, THIS NEW BRACKET HELPS HOLD THE PAD IN PLACE SO THAT WEAR, WHILE THE VEHICLE IS IN MOTION, DOES NOT OCCUR. THIS WOULD SUGGEST THE ORIGINAL PAD AND RETAINING CLASP WAS POORLY DESIGNED CAUSING ABNORMAL WEAR ON THE PARKING BRAKES. EVERY CHANCE I GET, I S

FUEL GAUGE NOT WORKING PROPERLY CAUSING TRUCK TO STOP IN THE MIDDLE OF A FOUR LANE ROAD THIS GAS GAUGE PROBLEM HAS OCCURRED IN MY OTHER VEHICLE A 1997 MONTE CARLO AND MY DAUGHTERS LUMINA,SO THIS IS NOT AN ISOLATED INCIDENT. A PROBLEM OF THIS KIND COULD BE VERY DANGEROUS ON AN EXPRESSWAY. *NLM

VEHICLE FAILED STATE INSPECTION DUE TO AN INOPERABLE PARKING BRAKE. INSPECTOR CLAIMS OVER 50% OF NEW BODY STYLE SILVERADO'S/TAHOE'S/SUBURBAN'S HE INSPECTS FAIL DUE TO THE SAME PROBLEM. *NLM

CONSUMER COMPLAINED OF DEFECTIVE ENGINE MAKING CONSTANT NOISE. VEHICLE ALSO VIBRATED WHILE DRIVING. IN ADDITION, DEALER REPLACED WATER PUMP AND ENGINE BELTS. *AK

ANNOYING STEERING NOISE INSIDE VEHICLE AT STEERING COLUMN ONLY TO THE LEFT AT SLOW SPEEDS. SLOWER SPEED = LOUDER NOISE.*JB

THE VEHICLE EXPERIENCED THE SAME PROBLEM AS RECALL (ANTI LOCK BRAKE), #00V055000, HOWEVER THE VEHICLE IDENTIFICATION NUMBER WAS NOT INCLUDED IN THE RECALL. *JB

CONSUMER WAS CONCERNED WITH THE LIST OF RECALLS REGARDING THE VEHICLE. *TS *JB

THE GAS PEDAL STICKS SOMETIMES. IN ORDER TO ACCELERATE, YOU MUST PRESS THE PEDAL HARD AND THEN THE TRUCK TAKES OFF. THERE'S NO STEADY ACCELERATION. *NLM

MY 2000 CHEVROLET 2500 SILVERADO THROTTLE STICKS SHUT WHEN FIRST STARTED. MINE HAS A 6.0 LITER V-8, BUT I KNOW SEVERAL PEOPLE WITH DIFFERENT ENGINES AND MODEL YEARS WITH THE EXACT SAME PROBLEM. THE PEDAL STICKS SO HARD THAT IT TAKES A GREAT DEAL OF EFFORT TO MAKE IT RELEASE RESULTING IN LARGE BURST OF SPEED AND LOSS OF CONTROL. THE DEALERS REFUSE TO CORRECT EXCEPT UNDER WARRANTY WHICH I NO LONGER HAVE. THE FACTORY KNOWS THERE IS A PROBLEM AND DEALERS ACKNOWLEDGE AS WELL BUT WILL NOT CORRECT WITHOUT BEING PAID. THIS IS A VERY DANGEROUS PROBLEM. WE HAVE HAD SEVERAL NEAR MISSES. *NLM

THE PARKING BRAKE WORE OUT AT 20,000 MILES. THE DEALER WAS NOTIFIED AT REPAIRED THE PROBLEM BUT AT 53,000 MILES THE PROBLEM REOCCURRED. *NLM

MY 4X4 ,6.0 LITER 3/4 TON SILVERADO HAS A STICKY GAS PEDAL. THE PROBLEM MAKES THE TRUCK LEAP FORWARD AND I HAD JUST AVERTED HITTING VEHICLES NUMEROUS TIMES. THE PROBLEM DOES NOT LAST FOR LONG. I HAVE NOT CONTACTED THE DEALER AS IT HAS 50,000 MILES NOW. *JB

WHILE DRIVING THE VEHICLE EXPERIENCED SUDDEN ACCELERATION. *NLM
