2001 Chevrolet Impala SERVICE BRAKES, HYDRAULIC

THE ABS LIGHT COMES ON WITHOUT WARNING. WHEN THIS HAPPENS THE BRAKES FREEZE UP AND GRINDS AND IT TAKES A LONG TIME TO COME TO A COMPLETE STOP. I FIRST STARTED HAVING THESE PROBLEMS IN 2008 AND I'VE REPLACED BOTH HUBS ,ROTORS, HARNESS,AND SENSOR. THIS IS A MAJOR PROBLEM THAT INTERFERES WITH BOTH STOPPING AND ACCERATING BECAUSE IT MAKES THE CAR STALL . I HAVE TO KIDS AND THIS ACTION TERRIFIES THEM WHENEVER IT HAPPENS. I 'VE SEEN ALOT OF THE SAME COMPLAINTS FROM COMSUMERS AND I THINK TIMES TIME FOR GMC TO DO SOMETHING ABOUT THIS BEFORE IT CAUSES A FATAL ACCIDENT. I'VE COME VERY CLOSE TO BEING IN AN ACCIDENT DO TO THIS PROBLEM AND I'VE TRIED EVERYTHING TO FIX IT AND I'M GETTING THE SAME RESULTS.SOMEONE NEEDS TO CALL A RECALL ON THE 2001 IMPALA ABS SYSTEM AND SOON. *TR

ABS SYSTEM MAKE GRINDING NOISE LIGHT COMES ON CAR IS HARD TO STOP AND IS DIGGING INTO NEW ROTORS. *TR

I HAVE ROTATED MY FRONT ROTORS AND CHANGED BRAKE PADS 2. I ALSO HAVE REPLACED THEM AND 6 MONTHS LATER I HAVE TO TURN THE NEW ONES. THEY HAVE WARPED AND MY CAR VIBRATES VERY BAD. *TR

2001 CHEVROLET IMPALA ABS / TRACTION CONTROL PROBLEM ENGAGES BRAKES INTERMITTENTLY AND SPONTANEOUSLY WITHOUT WARNING. EXCESS HEAT BUILDS UP AND CAUSES BRAKE FLUID LOSS. POTENTIAL FOR BRAKE FAILURE EXISTS. PERHAPS THE GOVERNMENT COULD DO SOMETHING ABOUT THIS. YEAH, RIGHT. I PREDICT THAT YOU GUYS WILL FAIL THE CONSUMER YET AGAIN. *TR

THE ANTI-LOCK BRAKING SYSTEM WOULD ENGAGE WHEN THE BRAKE PEDAL WAS DEPRESSED AT LOW TO MODERATE SPEEDS. THIS OCCURRED ON DRY PAVEMENT AND SEEMED TO EXTEND THE LENGTH OF TIME NEEDED TO COME TO A COMPLETE STOP. THE DEALERSHIP REPLACED THE HUB AND SENSOR. THE PROBLEM RECURRED. THE HUB AND SENSOR WERE ADJUSTED. THE PROBLEM RECURRED. THE DEALERSHIP HAD TO REPLACE THE WIRING HARNESS TO CORRECT THE PROBLEM. OLD PARTS WERE NEVER OFFERED IN RETURN. THE REPAIR WAS NOT COVERED BY WARRANTY. *JB

DT*: THE CONTACT STATED WHILE TURNING TO THE LEFT AT LOW SPEEDS THE ANTILOCK BRAKES ACTIVATED AUTOMATICALLY CAUSING THE VEHICLE TO COME TO A COMPLETE STOP IN TRAFFIC. THE DEALERSHIP DETERMINED THE TRACTION CONTROL DEVICE WAS DEFECTIVE AND HAS REPLACED IT FOUR TIMES, BUT THE PROBLEM PERSIST. THE MANUFACTURER WAS ALERTED.*AK

DT: THE CONSUMER COMPLAINED ABOUT AN ABS BRAKE PROBLEM. THE FIRST TIME THE DEALERSHIP GROUNDED THE ROTORS. ANOTHER TIME THEY REPLACED THE ROTORS, AND ANOTHER TIME THEY REPLACED THE BRAKES. THEY HAD TO REPLACE THE DRUMS, ROTORS, AND PADS. THE CONSUMER BELIEVED THAT THE PROBLEM STARTED SOMETIME IN JULY 2002. THE CONSUMER HAS RECORDS OF ALL THE MAINTENANCE THAT WAS DONE TO THE VEHICLE. THERE HAVE BEEN NO ACCIDENTS AS OF YET. SINCE THE LAST REPAIR THE ONLY PROBLEM WAS THE NOISE WHEN BACKING UP. *AK *NM

- I HAVE A 2001 IMPALA LS 3.8L WITH TRACTION CONTROL - SERVICE TRACTION CONTROL LIGHT CAME ON. ABS BRAKES WOULD ENGAGE WHEN MAKING A RIGHT HAND TURN (LOOSE OR TIGHT TURN) AND WHEN ACCELERATION FROM A STOP. THERE WAS NO REASON FOR THE ABS TO ENGAGE WHEN MAKING THESE TURNS, ROAD CONDITIONS WERE PERFECT. - I TOOK THE CAR TO THE SHOP AND THEY SAID THE SPEED SENSOR HAS FAILED DUE TO ENVIRONMENTAL CONDITIONS (PLEASE REFERENCE NHTSA CAMPAIGN ID NUMBER 05V379000 FOR A RECALL ON GM PICKUP TRUCKS AND SUV'S). MY CAR IS NOT COVERED UNDER THIS CAMPAIGN BUT THE PROBLEM DESCRIBE IN THE CAMPAIGN IS EXACTLY WHAT HAS FAILED IN MY SITUATION. - THE SHOP REPLACED THE RIGHT FRONT HUB BEARING AND WIRING HARNESS USING HUB KIT 6.307 AND SENSOR KIT 4.720 -PROBLEM WAS FIXED - I WOULD LIKE TO KNOW WHY CARS ARE NOT COVERED UNDER THE CAPAIGN LIKE TRUCKS AND SUV'S THAT HAVE THE SAME SPEED SENSOR.*JB

DT: 2001 CHEVROLET IMPALA. AT 6,500 MILES THE CONSUMER NOTICED THE BRAKES GRINDING. THE VEHICLE WAS TAKEN INTO THE DEALERSHIP ON JULY 7, 2003, AND SHE WAS TOLD IT WAS A NORMAL METALLIC PAD NOISE, AND THERE WAS NO CORRECTION NECESSARY. THERE HAVE BEEN NO CORRECTIONS TO THIS VEHICLE AT ALL. THE CONSUMER'S SON RECENTLY DROVE THE VEHICLE AND NOTICED THE PROBLEM HIMSELF. ALSO, WHILE DRIVING THE STEERING WHEEL WOBBLED. THE CONSUMER CONTACTED CHEVROLET, AND THEY RECOMMEND THE VEHICLE BE TAKEN BACK TO THE DEALERSHIP.*AK

2001 IMPALA FRONT AND REAR BRAKES COMPLETELY REPLACED.***NO ANSWER REQUIRED***. *MR THE CONSUMER STATED THE PADS WERE FALLING OFF IN HIS HANDS. THE ROTORS HAD SOME SCRATCHES ON THEM, BUT THEY COULD NOT BE MACHINED DOWN. THE CONSUMER ALSO HAD A 2001 CHEVROLET S-10 THAT HAD THE SAME BRAKE PROBLEM. *JB

2001 CHEVROLET IMPALA EXPERIENCING PROBLEMS WITH ACCELERATOR PEDAL AS WELL AS THE VEHICLE VIBRATING WHEN THE BRAKES ARE APPLIED. *MR THIS WOULD BECOME MUCH WORSE AT HIGHER SPEEDS. THE ORIGINAL BRAKE LININGS HAD COME OFF OF THE SHOES. ALL OF THE ROTORS WERE REPLACED AT 2781K MILES. THE ROTORS HAD TO BE TURNED 3 TIMES TO GET THEM FLAT. *SC *JB

I OWN A 2001 CHEVROLET IMPALA LS. THIS IS THE SECOND TIME I HAVE HAD TO REPLACE THE FRONT ROTORS. THE FIRST TIME THE VEHICLE ONLY HAD 20,000 MILES AND NOW I AM REPLACING THEM AGAIN 1 YEAR LATER WITH ONLY 46,000 MILES ON THE VEHICLE. I HAVE USED BOTH GM ROTORS AND ANOTHER MANUFACTURER AND BOTH ROTORS WARPED VERY PREMATURELY. I HAVE READ NUMEROUS OTHER COMPLAINTS ON THIS SITE REGARDING THE SAME EXACT PROBLEMS. I ALSO EXPERIENCE SEVERE VIBRATIONS WHEN BRAKING AT SPEEDS OF GREATER THAN 45 MPH. IT IS NOT NORMAL CAR MAINTENANCE TO HAVE TO REPLACE FRONT ROTORS EVERY 20, 000 MILES. I BELIEVE THERE MUST BE A DESIGN FLAW OR SOME OTHER EVENT CAUSING THIS SCENARIO.*AK

WHILE APPLYING THE ACCELERATOR PEDAL VEHICLE VIBRATED UNCONTROLLABLY. CONSUMER WAS ABLE TO MAINTAIN CONTROL OF THE VEHICLE, AND DROVE IT TO THE DEALER FOR INSPECTION. MECHANIC DETERMINED THAT THE FRONT ROTORS NEEDED TO BE RESURFACED, AND RESURFACE THEM. AT 21,222 MILES THE PROBLEM RECURRED, AND THE FRONT/REAR ROTORS WERE RESURFACED. AT 29,776 THE PROBLEM RECURRED , AND THE FRONT ROTORS WERE REPLACED, AND THE REAR ROTORS WERE RESURFACED. HOWEVER, THE PROBLEM RECURRED. *AK THE FRONT BRAKE PAD ON THE DRIVERS SIDE FELL FROM BACKING RENDERING THE FRONT BRAKE USELESS. GM STATED THAT FRONT BRAKE PADS WERE NOT COVERED AFTER 12000 MILES. THE CONSUMER STATED THAT HE WOULD LIKE GM TO COVER AT LEAST 50% OF COST. AFTER 4 INCIDENTS OF WARPED ROTORS THE PADS FELL APART. *TC

CAR WAS VIBRATING WHEN BREAKS APPLIED ESPECIALLY AT SPEEDS OVER 45 MPH. PROBLEM WITH ROTORS BEING WARPED, WRINKLED AND WAVY ACCORDING TO DEALER SERVICE. HAD TO HAVE FRONT ROTORS REPLACED AT 17,000 MILES ON AUG 6TH 2002. ON MAY 23RD 2003 HAD TO HAVE FRONT ROTORS AND REAR ROTORS REPLACED AGAIN AT 28,000 MILES. CAR IS BEGINNING TO VIBRATE AGAIN MILEAGE IS 42,000.00 . I FEEL THAT THERE IS A PROBLEM WITH THIS CAR AND SHOULDN'T HAVE TO HAVE THE ROTORS REPLACED EVERY FEW THOUSAND MILES. *AK

ANTI-LOCK BRAKES STOPPED WORKING WHEN I DROVE UPON A CURB. VEHICLE WOULD NOT STOP. CONSTANT BRAKE PRESSURE WAS APPLIED. BRAKE WERE MAKING A MOANING SOUND BUT NOT ENGAGING. THERE WAS NO LOCKED WHEEL SKIDS. SPEED WAS AT APPROX. MPH.*AK

AT 25963 MILES AND AGAIN AT 40196 MILES THE BRAKE ROTORS ON THE REAR OF THE CAR HAD TO BE REPLACED. FRONT ROTORS HAD TO BE RESURFACED, AND BRAKE PADS REPLACED. CHEVROLET CLAIMS THIS IS NORMAL WEAR, BUT HAD PREVIOUSLY INDICATED THAT THEY WERE HAVING A PROBLEM WITH ROTORS THAT WERE FLAKING AND WARPING AT 15,000 MILES. CHEVROLET REFUSED TO REPAIR UNDER WARRANTY.

VEHICLE VIBRATED AND SHOOK AT HIGH SPEED (ABOVE 50MPH) WHEN BRAKES WERE APPLIED. SCRAPING NOISES WERE ALSO HEARD. DEALER WOULD ONLY LOOK AT BRAKES IF DIAGNOSTIC FEE WAS PAID. RESULT WAS THAT ROTORS WERE WARPED ON THE FRONT OF THE VEHICLE AND PITTED AND SCORED ON THE REAR OF THE VEHICLE. VEHICLE HAS 18K FOR MILEAGE. BRAKE PADS ON BOTH FRONT AND REAR HAD 75% WEAR REMAINING. FRONT ROTORS WERE TURNED AND PADS REPLACED. REAR ROTORS AND PADS WERE REPLACED.OEM DESIGN OF REAR PADS HAS A VERTICAL GROOVE IN THE MIDDLE WHICH COLLECTS DUST, DIRT AND DEBRI CONTRIBUTING TO THE WEAR ISSUE. REPLACEMENT PADS DO NOT.*AK

THE BRAKE ROTORS WERE WARPED WHICH CAUSED VIBRATION WHILE BRAKING. THE VEHICLE WAS TAKEN TO THE DEALER WHO STATED THAT THE ROTORS WERE WARPED BECAUSE THE VEHICLE WASN'T USED ENOUGH. THE DEALER REFACED BOTH BRAKE ROTORS. *AK *CB *NLM

MY 2001 CHEVORLET IMPALA HAS EXPERIENCED PROBLEMS WITH THE ROTORS WEARING VERY EARLY. NEW ROTORS WORE OUT AFTER ONLY 7,000 MILES. AFTER BEING "FIXED" BY 2 DIFFERENT MECHANICS, THE CAR CONTINUES TO EXPERIENCE "SHAKING OF THE STEERING WHEEL" WHEN THE BRAKE IS APPLIED. THE VEHICLE ALSO HAS A TENDENCY TO "SLIDE" VERY EASY ON TURNS WHEN THE ROADS ARE WET. BOTH MECHANICS INDICATED THAT THE BRAKES WERE REPAIRED BUT THE UNDERLYING PROBLEM HAS YET TO BE IDENTIFIED. ON WET ROADS, THIS IS CLEARLY A HAZARD. *LA

THE CONSUMER STATED THAT WHILE DRIVING AT ANY SPEED AND WITH NO WARNING, THE BRAKE ROTORS WOE OUT AND CAUSED EXTENDED STOPPING DISTANCE. THE DEALER WAS NOTIFIED. *AK THERE WAS A PULSATION WHEN THE BAKES WERE APPLIED. *SCC *JB

WHEN THE BRAKES WERE APPLIED, THERE WAS NOISE. THE CONSUMER WAS INFORMED THE NOISE WAS DUE TO RUST BUILD UP ON THE ROTORS. *JB

BRAKE ROTOR - REPEATED WARPAGE - 4 OCCURRENCES AND67,000 MILES.*AK

DEFECTIVE ROTORS. WARP EVERY 10,000 TO 15,000 MILES COULD CAUSE BRAKE FAILURE LEADING TO ACCIDENT. TS

THERE IS THIS VIBRATING FEELING THAT ONLY HAPPENS WHEN THE BRAKES ARE BEING APPLIED AT ANY SPEEDS. CONTACTED DEALER, AND THE DEALER REPLACED ROTORS ON VEHICLE.*AK

SEVERE VIBRATION WHEN APPLYING BRAKES AT SPEEDS GREATER THAN 45 MPH.*AK
