METAL BRAKE LINES RUSTED PREMATURELY @ 29,900 MILES CAUSING BRAKE LINE TO RUPTURE. THIS CAUSED BRAKE FAILURE. TRUCK HAD TO BE TOWED TO DEALER WHO DIAGNOSED RUSTED BRAKE LINES. FOR FUTURE SAFETY ALL METAL BRAKE LINES ON TRUCK REQUIRED REPLACEMENT. FAILURE OCCURRED IN WORK PARKING LOT SO NO ACCIDENT OCCURRED DUE TO FAILURE.
I HAD A MINOR VEHICLE ACCIDENT WHEN I APPLIED THE BRAKES THEY WENT STRAIGHT TO THE FLOOR. I HAND MY VEHICLE TOWED TO SHOP AND IT WAS FOUND THAT THE BRAKE LINES HAD RUSTED THRU IN THE BRACKET ON THE FIREWALL.
NOTICED A PUDDLE OF FLUID ON THE GARAGE FLOOR. INVESTIGATED AND FOUND IT TO BE BRAKE FLUID. THE ENTIRE RESERVOIR EMPTIED ON THE FLOOR AFTER A DAY. I HAD A HOLE IN ONE OF THE BRAKE LINES UNDER THE DRIVERS SIDE. LOOKING UNDER THE TRUCK ALL THE LINE WERE TERRIBLY CORRODED AND COULD BREAK AT ANY TIME . TAKING IT TO MY MECHANIC NEXT WEEK TO REPLACE ALL THE LINES. 9/1/2015
I DRIVE A COMPANY TRUCK DURING THE WEEK AND MAKE A HABIT OF DRIVING MY SIERRA ONCE A WEEK AS WELL. I WAS GOING DOWN THE DRIVEWAY TO THE MAIN ROAD WHEN THE PEDAL FELL TO THE FLOOR. NO BRAKES WHATSOEVER. I USED THE EMERGENCY BRAKE TO COME TO A SAFE STOP. I LOOKED UNDER THE HOOD TO REALIZE THAT THE BRAKE LINES WERE RUSTED AND HAD BLOWN A HOLE. THIS TRUCK IS NOT THAT OLD AND I DO NOT LIVE IN A NORTHERN STATE WHERE SALT CORROSION IS AN ISSUE. I BABY MY TRUCK AND KEEP IT UP. I LATER DID A SEARCH ON THE WEB AN FOUND OUT THAT THOUSANDS OF OTHERS ARE HAVING THIS ISSUE AS WELL. THIS IS RIDICULOUS, THIS IS A BAD MATERIAL CHOICE FOR BRAKE LINES. GMC NEEDS TO REALIZE THIS AND RECALL ALL OF US AND INSTALL COATED, OR BETTER YET, BRAIDED/POLY-COVERED LINES TO MAKE SURE THIS NEVER HAPPENS AGAIN. WHAT IF I WERE TRAVELING AT A HIGHER RATE OF SPEED AND HAD MY FAMILY IN THE CAR? I CAN SEE THEIR STAND ON THIS BEING A MAINTENANCE ISSUE, BUT I HAVE FRIENDS WITH EARLY 80'S AND 90'S MODEL TRUCKS THAT STILL HAVE THE ORIGINAL BRAKE LINES IN THEM, NOT CORRODED OR RUSTED, AND STILL WORK GREAT. GET ON THE BALL GMC AND TAKE RESPONSIBILITY FOR THIS. *TR

WHEN TRAVELING THROUGH AN INTERSECTION AT A GREEN LIGHT ANOTHER VEHICLE ILLEGALLY ENTERED THE INTERSECTION. I SAW THE VEHICLE AND ATTEMPTED TO STOP BUT WHEN I HIT THE BRAKES THE PEDAL WENT DOWN TO THE FLOOR AND NO BRAKING ACTION OCCURRED. I WAS TOLD I BLEW A BRAKE LINE. THE CAR WAS REPAIRED OF THE DAMAGE FROM THE ACCIDENT BUT I HAD TO PAY FOR THE BRAKE LINE REPAIR. AFTER GETTING THE TRUCK BACK I BROUGHT IT BACK TO THE REPAIR SHOP FOR AN ALIGNMENT WITHIN A FEW DAYS. WHILE THE REPAIR SHOP WAS DRIVING THE CAR IN FOR THE ALIGNMENT A SECOND BRAKE LINE BLEW. THERE IS NOT A RECALL FROM GMC AND THERE NO REASON WHY THE BRAKES LINES SHOULD BE RUSTING OUT AND BLOWING ON A CAR THAT IS WELL MAINTAINED. *TR
BRAKE LINE BURST WHEN I PUMPED BRAKE PEDAL PRIOR TO START OF TRAILERING A HORSE TRAILER. GMC DEALER STATED BRAKE LINES WERE RUSTED THROUGH. DEALER HAD INSPECTED VEHICLE WEEK BEFORE DURING TUNE-UP AND DID NOT NOTIFY ME OF RUST OR ISSUES WITH BRAKE AND FUEL LINES RUSTING IN GM TRUCKS. I FOUND REPORTED ISSUES WITH RUSTING BRAKE LINES IN GM TRUCKS PER MY OWN RESEARCH. BRAKE LINES ARE BEING REPLACED AT MY EXPENSE. *TR
BRAKE LINES RUSTED OUT RESULTING IN BRAKE FAILURE, LUCKILY IT HAPPENED AT A COMPLETE STOP ON THE SIDE OF A ROAD. *JS
TL* THE CONTACT OWNS A 2007 GMC SIERRA. THE CONTACT STATED THAT WHEN THE VEHICLE WAS DECELERATED, THE ANTI LOCK BRAKING SYSTEM WOULD ACTIVATE ONCE THE VEHICLE'S SPEED WAS BELOW 5 MPH, CAUSING AN INCREASE IN STOPPING DISTANCE. THE CONTACT TOOK THE VEHICLE TO THE DEALER AND WAS TOLD TO REMOVE THE FUSE. THE DEALER DID NOT REPAIR THE VEHICLE. THERE WAS A MANUFACTURER'S RECALL FOR THE FAILURE HOWEVER, THE CONTACT'S VEHICLE WAS NOT INCLUDED IN THE RECALL. THE FAILURE MILEAGE WAS UNKNOWN AND THE CURRENT MILEAGE WAS 50,000.
BRAKES FAILED, VEHICLE BROUGHT TO A STOP USING 1ST GEAR AND PARKING BRAKE, NARROWLY AVOIDING ACCIDENT. PARKED IN PARKING LOT AND BRAKE FLUID DRAINED TO PAVEMENT. DEALER ADVISES REPLACEMENT OF ALL BRAKE LINES AS ALL ARE SEVERELY CORRODED (ESTIMATED COST - $2,400). VEHICLE IS EXACTLY 5 YEARS OLD WITH NOT MANY MILES. USED IN CANADA IN THE SUMMER AND FLORIDA IN WINTER MONTHS. ONLY EXPOSURE TO SALT AND SNOW IS WHEN ENCOUNTERED ON TRIPS TO AND FROM FLORIDA. VEHICLE WAS UNDERCOATED AT PURCHASE. VERY DANGEROUS FAILURE, MOST CERTAINLY MUST HAVE BEEN FATALITIES GIVEN THE NUMBER OF REPORTS AND COULD HAVE BEEN US YESTERDAY OR WHEN TOWING 5TH WHEEL RV. *KB
WHILE STOPPING AT SLOW SPEEDS ON DRY ROADS MY ABS BRAKES KICK IN CAUSING MY VEHICLE TO TAKE LONGER TO STOP THAN NORMAL. THE BRAKE PEDAL ALSO DROPS TOWARD THE FLOOR CAUSING ME TO THINK I HAVE LOST MY BRAKES COMPLETELY. THIS HAS JUST STARTED,AND HAS HAPPENED TO ME NUMEROUS TIMES. I NEVER NOW WHEN THIS WILL HAPPEN TO ME CAUSING ME TO BE ON EDGE EVERY TIME I HAVE TO STOP. I READ ABOUT THIS PROBLEM WITH GM TRUCKS AND WENT AND SPOKE WITH MY LOCAL DEALER'S SERVICE MANAGER. HE TOLD ME THAT THIS HAS BEEN AN ONGOING PROBLEM FOR YEARS. HE SAID THAT THERE WAS A RECALL ON CERTAIN MODEL YEARS,BUT MY YEAR TRUCK WAS NOT ON THE RECALL LIST. I ASKED HIM HOW IT WAS POSSIBLE THAT GM WOULD LET THE SAME PROBLEM GO ON NEWER YEAR MODELS WHILE FIXING OTHERS? HE SAID HE DID NOT KNOW. I ASKED HIM HOW MUCH IT WOULD COST ME TO HAVE THE SERVICE DEPARTMENT FIX MY TRUCK. HE SAID IT ALL DEPENDS ON WHAT PARTS WERE NEEDED TO MAKE THE REPAIRS,AND COULD COST ME ANYWHERE FROM $150.00 TO $2,000.00. I DON'T UNDERSTAND HOW GM CAN GET AWAY WITH CHARGING SOME CUSTOMERS TO FIX THE SAME PROBLEM THAT HAS BEEN TAKEN CARE OF UNDER RECALLS IN THE PAST. THE SERVICE MANAGER TOLD ME I COULD PULL THE FUSE ON MY ABS SYSTEM AND THE PROBLEM WOULD STOP,OF COURSE DOING THIS WOULD MEAN I WOULD NOT HAVE ABS BRAKES ANY LONGER, OR I COULD WAIT AND SEE IF MY MODEL YEAR MAKES THE RECALL LIST IN THE FUTURE. WHEN I PAY GOOD MONEY FOR A SAFETY ITEM ON MY TRUCK,I EXPECT IT TO LAST LONGER THAN 42,000 MILES,AND I DON'T THINK I SHOULD HAVE TO PLAY RUSSIAN ROULETTE AND DRIVE A TRUCK WITH UNSAFE BRAKES HOPING IT WILL BE PUT ON THE RECALL LIST IN THE FUTURE. THIS PROBLEM NOT ONLY MAKES MY TRUCK UNSAFE FOR ME AND MY FAMILY,IT ALSO MAKES IT UNSAFE FOR EVERYONE NEAR IT AS I DRIVE DOWN THE STREETS,AND HIGHWAYS. PLEASE DON'T LET GM GET AWAY WITH LETTING THIS SAFETY PROBLEM GO UNFIXED JUST BECAUSE MY MODEL YEAR TRUCK IS NOT ON THE RECALL LIST. *TR
