1999 GMC SIERRA 1500 Complaints

OVER THE PAST 3 YEARS LIGHTED ODOMETER AND DRIVE DISPLAY FLICKER ON AND OFF. NOTICED THAT DISPLAY WOULD NOT WORK IN COLD TEMPS. APPROXIMATELY 6 MONTHS AGO LOST ALL DISPLAY. VEHICLE HAS APPROXIMATELY 96000 MILES ON IT. *TR

BRAKES FAILED DUE TO BRAKE LINE BURSTING BECAUSE OF CORROSION ON 1999 GMC TRUCK. *TR

1999 GMC SIERRA TRUCK HAD COMPLETE BRAKE FAILURE CAUSING ME TO HIT THE CAR IN FRONT OF ME AT A STOP LIGHT. NO INDICATIONS OF BRAKE PROBLEMS AND WHEN ATTEMPTING TO SLOW FOR THE LIGHT, THE BRAKE PEDAL WENT TO THE FLOOR. *TR

SEVERE CORROSION OF THE BRAKE LINES BECAME APPARENT DURING A SUDDEN APPLICATION OF THE BRAKES WHICH CAUSED MULTIPLE BRAKE LINES TO RUPTURE AND LEAVE THE VEHICLE WITH NO BRAKES SINCE A LINE FROM THE MASTER CYLINDER TO THE ABS UNIT FRONT LEFT INPUT AND THE ABS TO THE REAR T LINE BLEW SIMULTANEOUSLY. WHEN REMOVING THE DAMAGED BRAKE LINES THEY LITERALLY CRUMBLED TO PIECES DUE TO CORROSION. DURING THE REPAIR TO THE BRAKE LINES SEVERE CORROSION WAS NOTED ON THE FUEL LINES ALSO.

WHILE I DRIVING MY 1999 GMC SIERRA 1500 PICKUP,THE BRAKE ACTED VERY SOFT WHEN I WAS COMING TO A STOP ON THE ROADWAY. I THOUGHT AT FIRST THAT I WAS LOW ON BRAKE FLUID. BUT WAS ABLE TO DRIVE THE TRUCK TO MY MECHANIC AND HE CHECKED IT OUT AND FOUND THE BRAKE LINES HAD CORROSION AND A SMALL HOLE OPENED UP THROW BRAKE FLUID ALL UNDER THE UNDERCARRIAGE IN THE REAR DRIVERS SIDE OF THE TRUCK. HE TOLD ME THAT THIS ISN'T THE ONLY TRUCK HE HAS SEEN THIS PROBLEM. I FEEL THAT SOMETHING NEEDS TO ADDRESSED SOON, BEFORE PEOPLE GET HURT OR KILLED BECAUSE OF THE LOSS OF THERE BRAKES. I WAS JUST LUCKY THAT I WAS DRIVING DOWN A HILL AND THE NORMAL SPEED LIMIT. I THINK THIS PROBLEM HAS BEEN OCCURRING AND NEEDS TO BE ADDRESSED TO GMC TO DO A RECALL ON ALL THERE 1999 GMC TRUCKS. *TR

MY TRUCK WAS PARKED. I STARTED MY TRUCK. I APPLIED THE BRAKE TO PUT MY TRUCK IN GEAR. THE BRAKE PEDAL WENT COMPLETELY DOWN TO THE FLOOR. I INSPECTED UNDER MY TRUCK, AND THERE WAS A PUDDLE OF BRAKE FLUID UNDER THE DRIVER'S SIDE AREA ON THE CEMENT. I SAW THAT ALL THE BRAKE LINES CONNECTED TO THE ABS ELECTRO-HYDRAULIC CONTROL UNIT ARE SEVERELY RUSTED, AND ONE OF THEM WAS LEAKING SEVERELY. I HAD MY TRUCK TOWED HOME. THERE WAS NO WARNING LIGHT ON THE DASH THAT WAS BLINKING TO TELL ME I THAT I WAS HAVING A PROBLEM WITH MY BRAKES. THEY WERE WORKING FINE PRIOR TO THIS FAILURE. I WILL DOCUMENT THE CONDITION OF THE BRAKE LINES WITH A PICTURE AND BRAKE MECHANIC WITNESSES BEFORE ANY REPAIRS. I AM IN THE PROCESS OF LOCATING A BRAKE REPAIR BUSINESS. *TR

THE BRAKE LINES UNDER THE DRIVERS DOOR ON THE FRAME ARE ALL RUSTED AND HAVE STARTED TO LEAK FROM EXCESSIVE CORROSION. JUST NOTICED THE LEAK AS THE TRUCK WAS PARKED OUTSIDE OUR HOUSE. *TR

TL*THE CONTACT OWNS A 1999 GMC SIERRA 1500. WHEN THE CONTACT ATTEMPTED TO STOP THE VEHICLE, THE BRAKE PEDAL EXTENDED TO THE FLOORBOARD. THE CONTACT SHIFTED INTO SECOND GEAR AND WAS ABLE TO STOP THE VEHICLE. THE CONTACT INSPECTED THE VEHICLE AND SAW THAT THE BRAKE LINES WERE CORRODED AND SEPARATED. THE CONTACT CALLED THE MANUFACTURER WHO STATED THAT THERE WERE NO RELATED RECALLS. THE CONTACT PLANNED TO HAVE THE VEHICLE REPAIRED. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 30,000.

UPON APPLYING THE BRAKES ON TO A 1999 GMC SIERRA THE BRAKE LINE RUPTURED, SPEWING BRAKE FLUID ONTO PAVEMENT AND CAUSING NEAR IMMEDIATE LOSS OF ALL STOPPING ABILITY. THE BRAKES WERE NOT APPLIED WITH EXCESSIVE PRESSURE AND THE SPEED WAS LESS THAN 15 MPH. COULD THERE BE A DEFECT WITH THE PLACING OF THE LINES THAT CAUSES THESE BRAKE LINES TO RUPTURE? UPON CHECKING WITH FRIENDS AND THE INTERNET IT HAS BECOME APPARENT THAT THIS IS NOT A RARE OCCURRENCE WITH THE GMC SIERRAS/SILVERADOS. THE REPAIR WAS QUOTED AT $1900 DOLLARS TO REPAIR THE RUPTURED BRAKE LINE AS WELL AS OTHER ASSORTED BRAKE PARTS. THIS VEHICLE HAS ALWAYS SEEMED TO HAVE SOME TYPE OF PROBLEM WITH THE BRAKES AND FOR SOME REASON IT SEEMS TO BE COMMON KNOWLEDGE WITHIN THE AUTOMOTIVE REPAIR INDUSTRY THAT THIS SPECIFIC VEHICLE WILL DEVELOP PROBLEMS WITH ITS BRAKES. IF I WERE USING ANY SPEED WITH THIS RUPTURE OCCURRED, I AM SURE THE OUTCOME WOULD HAVE BEEN MORE SERIOUS. *TR

TL* THE CONTACT OWNS A 1999 GMC SIERRA 1500. THE CONTACT STATED THAT UPON STARTING THE VEHICLE, THE BRAKE WARNING LIGHT WAS ILLUMINATED. THE VEHICLE WAS SHUT OFF AND RESTARTED SEVERAL TIMES YET THE WARNING LIGHT REMAINED ILLUMINATED. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALER WHERE THE DEALER ADVISED THE CONTACT THAT BRAKE FLUID WAS LEAKING DUE TO RUST OF THE BRAKE LINE. SHE STATED THAT ALL OF THE BRAKE LINES WERE REPLACED BY A LOCAL MECHANIC. THE FAILURE MILEAGE WAS 94,542 AND THE CURRENT MILEAGE WAS 94,636. UPDATED 12/30/10. *LJ UPDATED 04/07/11
