1999 GMC Safari

DT: ABOUT A YEAR AGO THE PROBLEM BEGAN. WHEN BRAKING AT LOW SPEEDS ABOUT 5-10 MPH ABS KICKS IN AND A GRINDING SOUND OCCURS. THIS CAUSES EXTENDED STOPPING DISTANCES. ALL WHEEL DRIVE, ALL WHEEL ANTILOCK TO THE OWNER'S KNOWLEDGE. NO WARNING LIGHTS ILLUMINATED AND THE DEALER SAID THAT THE ABS SENSOR LOOKED CORRODED. THE VEHICLE WAS PUT ON THE DIAGNOSTIC MACHINE BUT IT SHOWED NO CODES. WHEN THE ABS FUSE IS PULLED THE CAR WORKS FINE BUT HAS NO ABS. THE OWNER HASN'T DISCONNECTED THE ABS FUSE. THE VEHICLE HAS NOT BEEN REPAIRED YET AND THE PROBLEM HAS REMAINED ABOUT THE SAME. THE PROBLEM OCCURS ABOUT 90 PERCENT OF THE TIME DURING LOW SPEED BRAKE APPLICATIONS.*AK *NM

ANTI LOCK BRAKE LIGHT IS ON. REPLACED ALL WORN PADS AND SHOES. LIGHT WILL NOT RESET. THE VAN WILL NOT PASS UTAH SAFTY INSPECTION WITH LIGHT ON. NOT SURE OF HOW SAFE THE VAN IS. GMC HAS A KNOWN TRACK RECORD OF SAFTY ISSUE WITH THEIR ANTI LOCK BRAKES. THEY RISK FAMILIES HEALTH BY NOT RESOLVING THE KNOWN ISSUE WITH THEIR ANTI LOCK BRAKE SYSTEMS. *AK

CONSUMER STATES THERE IS DIFFERENTIAL WEAR BETWEEN THE LEFT AND FRONT BRAKE PADS, DEALER STATED THIS WAS NORMAL WEAR, CONSUMER STATES THE LEFT FRONT CALIPER WAS NOT RELEASING PRESSURE ON PADS TO ROTOR CAUSING EXCESSIVE WEAR, RIGHT FRONT CALIPER FROZEN OR PARTIALLY FROZEN CAUSING LEFT FRONT PADS TO DO ALL OR MOST OF THE BRAKING, AND WARPED OR OTHER DEFECTS IN THE LEFT FRONT ROTOR, DEALER STATED NEW ROTORS WERE NEEDED, FRONT BRAKE PADS WERE WORN, AND REAR BRAKES WERE OUT OF ADJUSTMENT, CONSUMER ALSO STATES THERE IS A PULSATING GRINDING NOISE COMING FROM THE LEFT. *SLC

FRONT ROTORS TURNED @ 16,000 MILES DUE TO SHIMMY. PADS WERE NOT REPLACED. NO COST-COVERED UNDER WARRANTY. VEHICLE NOW HAS 29,000 MILES AND SHIMMY RETURNED. DEALER REPLACED PADS/TURNED ROTORS AND REPLACED SHOES/TURNED DRUMS AT MY EXPENSE.(NOT COVERED UNDER WARRANTY). I BELIEVE THAT THIS IS EXCESSIVE BRAKE WEAR AND THE MANUFACTURER CLAIMS THAT THIS IS NORMAL WEAR AND NOT COVERED. VEHICLE NOW HAS ROTORS THAT WERE TURNED TWICE. GUESS WHO GOING TO PAY AGAIN (FOR NEW ROTORS) AT NEXT PAD REPLACEMENT.*AK

ACCIDENT OCCURRED DUE TO ABS FAILURE. ACCIDENT OCCURRED APPROX. 10 MILES FROM MY RESIDENCE IN A SCHOOL ZONE. I WAS TRAVELING AT APPROX. 30 MPH (35 MPH POSTED), FOLLOWING OTHER AUTOS AND WHEN AUTOS IN FRONT OF ME SLOWED, I PRESSED THE BRAKE PEDAL AND IT WENT TO THE FLOOR WITH NO POSITIVE RESULTS. THERE WAS NO WARNING THAT THE BRAKES WERE GOING TO PERFORM IMPROPERLY AND I WAS NOT ATTEMPTING TO MAKE A SUDDEN STOP. DUE TO THE BRAKE FAILURE, I IMPACTED THE REAR-END OF ANOTHER VEHICLE, WHICH SUBSEQUENTLY HIT THE AUTO IN FRONT OF IT. HAD VAN REPAIRED THROUGH A SHOP THAT WAS OF PREFERRED STATUS WITH INSURANCE COMPANY. UPON PICKUP OF VAN, WAS TOLD THAT IT WAS CONFIRMED THAT AN ABS FAILURE CAUSED WRECK. NOTIFIED GMC CUSTOMER SERVICE AND AS PER THEIR REP., CASED CLOSED DUE TO THE FACT THAT THEY DID NOT INSPECT DAMAGED VAN--NOR DID THEY WANT TO OFFER INSPECTION/COMPUTER ANALYIS OF VEHICLE NOW. THIS COULD HAVE BEEN A FATAL ACCIDENT--CHILDREN AS PASSENGERS IN THIS VEHICLE AND OTHERS. GMC SHOULD TAKE SOME RESPONSIBILITY--THEIR ABS TRACK RECORD SPEAKS VOLUMES AND THE OWNER'S MANUAL SAYS *NOTHING* ABOUT HAVING THE VEHICLE INSPECTED BY THEIR REPS BEFORE HAVING VEHICLE REPAIRED.*AK
