2007 GMC Sierra Brakes Problems

WHILE DRIVING VEHICLE, COMPLETE BRAKE FAILURE OCCURRED. NO TRAFFIC ON ROAD WAS ABLE TO COAST TO STOP WITHOUT ACCIDENT. QUICK INSPECTION SHOWED SEVERE BRAKE FLUID LEAK. AFTER TOWING, REPAIR SHOP FOUND RUPTURED HYDRAULIC BRAKE LINE DUE TO CORROSION, AND MULTIPLE OTHER SIMILAR WEAKENED SPOTS. ALL HARD LINES REPLACED. MANUFACTURER DECLINED WARRANTY ASSISTANCE. OF NOTE, VEHICLE PURCHASED NEW, WITH NO HEAVY DUTY USE, NOR HIGH MILEAGE. ORIGINAL PARTS IN MY POSSESSION FOR VERIFICATION.

TL* THE CONTACT OWNS A 2007 GMC SIERRA 1500. WHILE DRIVING 50 MPH, THE FRONT BRAKES INDEPENDENTLY STOPPED WORKING AND THERE WAS SMOKE COMING FROM THE FRONT BRAKES. THERE WERE NO WARNING INDICATORS ILLUMINATED. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. A LOCAL DEALER AND THE MANUFACTURER WERE NOT MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 217,385.

TL* THE CONTACT OWNS A 2007 GMC SIERRA 1500. WHILE DRIVING VARIOUS SPEEDS, THE ABS WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 05V379000 (SERVICE BRAKES, HYDRAULIC). THE MANUFACTURER WAS CONTACTED AT 866-996-9463 AND STATED THAT THE VIN WAS NOT INCLUDED IN THE RECALL. THE FAILURE MILEAGE WAS 82,983.

I LOST MY BRAKES WHILE DRIVING. THE BRAKE PEDAL WENT TO FLOOR. TOOK IT TO GMC DEALER WHERE PURCHASED AND WAS TOLD IT WAS CORRODED BRAKE LINES WHICH HAD TO BE REPLACED.$1300 TOTAL COST. NO BRAKE WARNING LIGHT EVER APPEARED!!! NO OTHER RUST/CORROSION WAS VISIBLE ON TRUCK BODY EXCEPT FOR BRAKE LINES. WAS TOLD THIS WAS AN ISSUE OF ALL GMC/CHEV. TRUCKS FROM THAT TIME SPAN.

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.

RUSTY BRAKE LINES LOST BRAKES, THINK THAT A VEHICAL SHOULD GO 10 YEARS WITHOUT BRAKE LINES RUSTING AWAY I WAS LUCKY WHEN THEY BROKE I WAS HOME BUT JUST GOT BACK FROM ANOTHER STATE AND WAS AT HIGHWAY SPEEDS.

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.

RUSTED OUT BRAKE LINE AT 72000 MILES. WHAT A DISAPPOINTMENT BUT IT DOESN'T LOOK LIKE I AM THE ONLY ONE. ITS A SHAME GM DOESN'T MAN UP AND CORRECT THE PROBLEM OF RUSTED OUT BRAKE LINES. LUCKILY I WAS IN FRONT OF MY HOUSE WHEN IT FAILED AND NOT RUNNING DOWN THE ROAD PULLING MY 4000 LB. BOAT. AND YES I HAVE READ ALL THE INFO ONLINE ABOUT THE NHTSB INVESTIGATING THIS PROBLEM AND LET GM OFF THE HOOK BY SAYING OWNERS SHOULD WASH THEIR CARS TO REMOVE THE ROAD SALT THAT CAUSED THIS PROBLEM. I GUESS FORD AND DODGE OWNERS CRAWL UNDER THEIR TRUCKS IN THE WINTER AND DO THIS AS THERE WAS NO INVESTIGATION ON THEM. BY THE WAY I LIVE IN TN WHERE WINTERS AREN'T THAT BAD. AND ONE OTHER THING WHAT MARKETING BUZZ SAW DECIDED IT WOULD BE BETTER NOT TO HAVE A SPLIT BRAKE FLUID RESERVOIR SO AT LEAST I WOULD HAVE 1/2 OF MY SYSTEM, HAD NO BRAKES FRONT OR REAR BECAUSE OF THIS.

TL* THE CONTACT OWNS A 2007 GMC SIERRA 1500. THE CONTACT STATED THAT THE VEHICLE EXPERIENCED A LOSS OF BRAKING ABILITY. WHILE DRIVING VARIOUS SPEEDS, THE CONTACT WAS ABLE TO STOP THE VEHICLE BY USING THE EMERGENCY BRAKE. THE FAILURE OCCURRED WITHOUT WARNING. THE VEHICLE WAS TOWED TO THE MECHANIC WHERE IT WAS DIAGNOSED THAT THE BRAKE LINES WERE DEFECTIVE AND NEEDED TO BE PATCHED. THE VEHICLE WAS REPAIRED; HOWEVER, THIS WAS THE THIRD INSTANCE OF THE FAILURE OCCURRING ON THE VEHICLE. WILDCAT CHEVROLET (5525 HOPKINSVILLE RD, CADIZ, KY) WAS CONTACTED AND CONFIRMED THE FAILURE, BUT THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 80,000.

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

TL* THE CONTACT OWNS A 2007 GMC SIERRA 1500. WHILE ATTEMPTING TO DRIVE FORWARD, THE BRAKES WOULD ERRONEOUSLY ACTIVE WHILE THE VEHICLE WAS IN MOTION. THE CONTACT ALSO INDICATED THAT THE CHECK ENGINE SENSOR LIGHT ACTIVATED AND REMAINED ILLUMINATED. THE CAUSE OF THE FAILURES WAS NOT DIAGNOSED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE FAILURE MILEAGE WAS 170,000.

BRAKE LINES FAILED ON MY 2007 GMC 1500 AND MY 2007 GMC 2500. IT APPEARS TO BE A COMMON PROBLEM WITH GMC VEHICLES FROM 2003 TO 2009. WHY WASN'T THESE VEHICLES RECALLED FOR THIS. I WAS TOLD THAT GMC WAS OFFERING A DISCOUNTED PRICE FOR FAILED BRAKE LINES, BUT THE DEALER CHARGED ME FULL PRICE. $1,667.00. THE DISCOUNTED PRICE WAS SUPPOSED TO BE $500.00.

AS I WAS TRAVELING ABOUT 35MPH APPROACHING A RED STOPLIGHT I PROCEEDED TO PRESS THE BRAKE PEDAL ALL THE WAY TO THE FLOOR, WITH NO BRAKING OF THE VEHICLE. LUCKILY I WAS ABLE TO QUICKLY SHIFT THE VEHICLE INTO NEUTRAL AND ENGAGE THE EMERGENCY BRAKE AND AVOID COLLISION. AFTER FURTHER INSPECTION I FOUND THE HARD BRAKE LINE RUNNING TO THE FRONT LEFT WHEEL HAD RUPTURED CAUSING THE LOSS OF BRAKE FLUID. THE LINE RUPTURED IN AN AREA WHERE IT WAS SEVERELY CORRODED AND UPON INSPECTION, THE OTHER HARD BRAKE LINES OF THE SYSTEM LOOKED SEVERELY CORRODED ALSO. ALL WILL HAVE TO BE REPLACED! THIS FAILURE COULD HAVE HAD A VERY BAD CONSEQUENCES AT A HIGHER SPEED, CLOSER PROXIMITY TO OTHER VEHICLES, OR WITH A LESS EXPERIENCED DRIVER! *TR

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

WHILE FOLLOWING OTHER NORMALLY TRAVELING VEHICLES DOWNHILL - VEHICLES IN FRONT CAME TO A STOP - BRAKE PEDDLE WAS FULLY DEPRESSED...NO RESPONSE...BRAKE FULLY APPLIED 2ND TIME...NO RESPONSE...RESULTING IN A REAR END COLLISION MULTIPLE VEHICLES...POSSIBLE TOTAL OF MY 2007 SIERRA. DAMAGES ARE VERY EXTENSIVE . INSURANCE TO INVESTIGATE GM BRAKE POSSIBLE CAUSE....AIRBAG DEPLOYED CHEST & NECK INJURIES....MANY OTHER INCIDENTS INVOLVING GMC BRAKE SYSTEMS. NEED IMMEDIATE NHTSA INVESTIGATIONS !! THIS COULD HAVE CAUSED A FATALITY. *TR

I WENT TO A LOCAL RECYCLE BUSINESS TO DROP OFF SOME CANS. UPON ENTERING THE BUILDING AT ABOUT 10 MPH, THIS GUY MOTION ME TO STOP AND WALKED IN FRONT OF THE TRUCK. I HIT THE BRAKES AND THE PEDDLE ALMOST WENT TO THE FLOOR, BUT DID STOP. JUST MISSING THE GUY THAT WALKED IN FRONT OF ME. REALIZING THAT A BRAKE LINE BROKE AND THAT THE DEALERSHIP WASN'T FAR AWAY, I DROVE REALLY SLOW TO GET THERE. I LEFT IT OVER THE WEEKEND. MONDAY THEY FOUND THAT THE BRAKE LINE THAT RUNS FROM FRONT TO REAR RUSTED AND BURST. $ 463. LATER I TOOK THE TRUCK HOME. AFTER CRAWLING UNDER THE TRUCK WHEN I GOT HOME, I NOTICED MORE BRAKE AND FUEL LINES WITH ALLOT OF RUST. I APPLIED SOME PAINT THAT'S SUPPOSED TO SLOW DOWN CORROSION. I'M GLAD I WASN'T ON THE HIGHWAY WITH MY GRAND KIDS IN THE TRUCK. OR WORSE, THE FUEL LINES COULD BREAK. I BELIEVE THERE SHOULD BE A RECALL ON THE BRAKE AND FUEL LINES. HOW MUCH WOULD IT HAVE COST FOR THE MANUFACTURER TO HAVE INSTALLED STAINLESS STEEL LINES WHEN THE TRUCK WAS BUILT? I'M SURE IT WOULDN'T HAVE BEEN MUCH. I HOPE NOBODY HAS TO DIE BEFORE ANYTHING IS DONE. THANKS FOR YOUR ATTENTION. *TR

RUSTED REAR BRAKE LINE TUBING - LOSS OF FLUID - NO BRAKING POWER ON ANY WHEELS - EMERGENCY BRAKE WAS THE ONLY WAY OF STOPPING THE TRUCK. *TR

2007 GMC SIERRA CLASSIC WITH APPROXIMATELY 54,000 MILES WAS BEING DRIVEN INTO A GARAGE TO HAVE WHEELS BALANCED. AS THE TECHNICIAN APPLIED THE BRAKES ENTERING THE GARAGE, THE BRAKE LINES ON THE FRONT DRIVERS SIDE OF THE VEHICLE RUPTURED AND THE BRAKE PEDDLE WENT TO THE FLOOR. BRAKE FLUID POURED OUT ONTO THE FLOOR AND THE BRAKES BECAME COMPLETELY UNUSABLE. IF THIS HAD HAPPENED A FEW HOURS EARLIER IN THE DAY AS I WAS TRAVELING ON STEEP MOUNTAIN HIGHWAYS IN WEST VIRGINIA I HAVE NO DOUBT AN ACCIDENT AND PROBABLE FATALITY WOULD HAVE OCCURRED. ALL RECOMMENDED MAINTENANCE HAD BEEN PERFORMED AT THE GM DEALER WHERE THE TRUCK WAS PURCHASED AND NO WARNINGS FROM GM WERE GIVEN THAT THE BRAKE LINES WERE SHOWING ANY SIGNS OF WEAR OR THAT A COMPLETE BRAKE FAILURE LIKE THIS COULD HAPPEN. *TR
