SERVICE BRAKES, SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS
BRAKE FAILURE DUE TO SEVERELY RUSTED BRAKE LINE AT DRIVER SIDE REAR WHEEL. RUST IS SEVERE ON ALL SURFACES UNDERNEATH VEHICLE. WILL REQUIRE COMPLETE REPLACEMENT OF ALL BRAKE LINES AND OTHER ASSORTED BRAKE COMPONENTS. ABS WAS MALFUNCTIONING PRIOR TO BRAKE LINE RUPTURE, LIKELY DUE TO CORROSION WITHIN WHEEL/HUB ASSEMBLY. THIS MALFUNCTION IS KNOWN TO GMC, AND OCCURS BY THE ABS ERRONEOUSLY SENSING WHEEL STOPPAGE AT LOW SPEED, CAUSING THE SYSTEM TO ACTIVATE AND INABILITY TO STOP. THIS HAS CAUSED NEAR MISSES IN PARKING LOT SITUATIONS, THUS THE ABS HAS NECESSARILY BEEN DISABLED UNTIL REPAIR (PULLING FUSE). NOT THE KIND OF ISSUES A LOW MILEAGE TRUCK SHOULD BE EXPERIENCING. *JB

SERVICE BRAKES
UPON APPLYING BRAKES TO SHIFT INTO REVERSE, PEDAL WENT TO FLOOR AND ALL WARNING LIGHTS CAME ON. HAD TRUCK TOWED TO GARAGE, AND UPON INSPECTION A METAL BRAKE LINE HAD RUSTED OUT. AFTER REPLACING BRAKE LINE GARAGE WAS BLEEDING BRAKES AND ANOTHER LINE FAILED. WAS TOLD BY MECHANIC THAT I SHOULD HAVE ALL THE METAL LINES REPLACED BECAUSE OF SEVER RUSTING OF THE METAL. THIS SEEMS TO BE MORE PREVALENT IN GENERAL MOTORS THAN ANY OTHER BRAND. I WAS TOLD THAT THE USE OF SALT BRINE SOLUTION IN OUR AREA FOR WINTER FREEZING IS THE REASON BEHIND THIS. I WAS TOLD THAT THE MECHANIC IS SEEING AT LEAST ONE VEHICLE A WEEK WITH THIS PROBLEM. *JS

SERVICE BRAKES
EXPERIENCED A COMPLETE LOSS OF SERVICE BRAKES. FORTUNATELY THIS OCCURED AFTER COMPLETING A TRIP WHILE TOWING A TRAILER. HAD THIS HAPPENED DURING THE TRIP SERIOUS INJURIES AND MULTIPLE DEATHS COULD HAVE BEEN THE RESULT. INVESTIGATION OF THE PROBLEM INDICATED PREMTURE RUSTING THROUGH OF THE STEEL BRAKE LINE TO THE RIGHT FRONT DISC BRAKE. THE BRAKE LINE TO THE LEFT FRONT CALIPER IS ALSO BADLY RUSTED. THE BRAKE LINES FROM THE MASTER CYLINDER ARE MILDLY RUSTED AS WELL.

SERVICE BRAKES
MY MOTHER BORROWED MY TRUCK TO RUN AN ERRAND ON HER WAY HOME SHE CALLED TO TELL ME THAT THE "SERVICE BRAKE SYSTEM" MESSAGE HAD APPEARED IN THE DIC. MOMENTS LATER THE VEHICLE LOST ALL STOPPING ABILITY. THANKFULLY DUE TO THE COMBONATION OF AN EMPTY ROAD GOOD DRIVING NO COLLISION OCURED. THIS MORNING I GO TO INVEGISTATE TO FIND COMPLETE RUST THROUGH ON TWO OF THE STEEL HYDRAULIC LINES LOCATED JUST BEHIND THE DRIVERS FRONT WHEEL. ALL STEEL LINES IN THIS TRUCK BRAKE, FUEL, AND, TRANSMISSION COOLER HAVE SIMILAR EXTENSIVE RUST DAMAGE. THIS IS EXTREMELY DANGERIOUS AND WILL BE EXPENSIVE TO REPAIR AS TO ENSURE SAFETY ALL METAL LINES WILL NEED CHANGING. I CAME TO FIND OUT THAT NOT ONLY IS THIS A VERY COMMON ISSUE WITH THESE TRUCKS BUT THAT GM IS DOING NOTHING TO HELP OWNERS NOR DO THEY OFFER CORRECT QUALITY OE STYLE REPLACEMENT LINES. I WAS QOUTED OVER $1000 BY TWO SEPERATE DEALERS IN MY AREA. MY TRUCK IS WELL TAKEN CARE OF AND IS DRIVEN MUCH LESS THAN THE NATIONAL AVERAGE THIS FAILURE HAS TRULY UPSET ME I DONT SEE BUYING ANOTHER GM PRODUCT IN THE FUTURE. *TT

WHEELS, TIRES
I PURCHASED BRIDGESTONE DUELER ALENZA HL TIRES AT 42509 ON 06/10/2009 AND ON 04/10/2011 I HAD A SLOW LEAK AND WENT TO BRIDGESTONE DEALER FOR REPAIR BUT NOTICED CRACKING IN TREAD. I WAS TOLD THIS WAS NORMAL! IN MAY 2013 MY MECHANIC SAID THIS CRACKING WAS DRY ROT AND I VERIFIED WITH OTHER TIRE DEALER TRUCK HAD 70693 MILE. THIS IS A 65000 MILE TIRE AND I ONLY HAD 14000 MILES BEFORE CRACKING STARTED- THIS IS A SAFETY HAZARD. I DID NOT GO BACK TO BRIDGESTONE DEALER BECAUSE I WAS GIVEN INACCURATE INFO AND I BOUGHT MICHELIN INSTEAD. I CALLED BRIDGESTONE AND THEY TOLD ME THERE WAS NOTHING THEY COULD DO AND "HAVE A NICE DAY."!!!! GOOD LUCK IF YOU BUY THESE! *TR

SERVICE BRAKES
THIS OCCURRED ON 8/13/2013 IN CENTRAL VIRGINIA AND THE TRUCK HAD 93461 MILES ON IT. WHILE MOVING MY 2004 GMC SIERRA 1500 TRUCK IN MY DRIVEWAY, MY BRAKE PEDAL WENT TO THE FLOOR BECAUSE THE REAR PASSENGER SIDE BRAKE LINE HAD BURST. THERE WAS NO WARNING LIGHT OR CHIME INDICATING A BRAKE SYSTEM ISSUE. THE DUAL MASTER CYLINDER SYSTEM ONLY PROVIDED ENOUGH BRAKING TO SLIGHTLY SLOW THE VEHICLE DOWN AND THE PARKING BRAKE DIDN'T HELP MUCH. I HAD IT TOWED TO A SHOP AND THEY SAID IT WAS DUE TO A CORRODED STEEL BRAKE LINE. THEY TOLD ME THAT THEY HAVE HAD TO REPLACE THESE LINES FREQUENTLY IN A LARGE NUMBER OF CHEVROLET AND GMC PICKUP TRUCKS. THEY REPLACED THE LINE AND I HAD PLANNED TO REPLACE ALL OF THE OTHER LINES IN A FEW MONTHS. TWO WEEKS AFTER THE REPAIR WAS DONE AND APPROXIMATELY 50 MILES LATER, ANOTHER LINE FAILED WHILE I WAS DRIVING APPROXIMATELY 45 MPH. AGAIN, THERE WAS NO WARNING LIGHTS OR CHIMES AND THE PEDAL WENT TO THE FLOOR. I ESTIMATE THAT THERE WAS APPROXIMATELY 5 TO 10% BRAKING POWER AND WAS UNABLE TO STOP THE VEHICLE. THE PARKING BRAKE DID HELP SOME BUT IS NO A SUBSTITUTE FOR A REAL EMERGENCY BRAKE THAT THE OLDER VEHICLES USED TO HAVE. ADDITIONALLY, IT IS NOT EASY TO LIFT YOUR FOOT UP TO IT AS THE PEDAL IS MOUNTED SOMEWHAT HIGH OFF THE FLOOR. THE REPAIR SHOP SAID THAT THIS TIME IT WAS A STEEL LINE RUNNING TO THE MASTER CYLINDER AND COULD BE SEEN LEAKING FLUID FROM INSIDE THE ENGINE COMPARTMENT. I HAD THEM REPLACE ALL THE LINES. I DON'T UNDERSTAND WHY THE NHTSA HASN'T DEMANDED A RECALL OF THESE VEHICLES FOR THE CORRODED BRAKE LINES AND THE FAILURE OF THE DUAL MASTER CYLINDER SYSTEM TO OFFER ANY RELIABLE METHOD OF STOPPING THE VEHICLE. I HAVE HAD SEVERAL OTHER VEHICLES THAT ARE MUCH OLDER THAN THIS TRUCK AND THEIR LINES WERE ALWAYS RUST FREE AND NEVER FAILED. ALTHOUGH MOST ARE NOT RECORDED HERE, THERE ARE THOUSANDS OF GM TRUCK OWNERS REPORTING THE SAME PROBLEM. *TR

SERVICE BRAKES, STRUCTURE:BODY, SUSPENSION
THIS IS AN OLD INCIDENT; HOWEVER, UNTIL JUST RECENTLY, I DID NOT REALIZE THERE WAS A WEBSITE SUCH AS YOURS. ALSO, I AM REPORTING A SPECIFIC INCIDENT, BUT ALSO WANT TO INCLUDE OTHER GENERAL INFORMATION. THE INCIDENT WHICH OCCURRED WAS RELATED TO MY BRAKE FLUID LINES RUSTING COMPLETELY THROUGH WHILE I WAS DRIVING DOWN THE ROAD WITH MY TWO SMALL GRANDCHILDREN. WHEN A VEHICLE STOPPED IN FRONT OF ME, I PUSHED ON MY BRAKES ONLY TO FIND I COULD NOT STOP. FORTUNATELY, THERE WAS A FIELD ON THE RIGHT SIDE OF THE ROAD AND I DROVE INTO IT, RATHER THAN HITTING THE VEHICLE. WHEN MY HUSBAND CHECKED THE BRAKES, THE LINES LITERALLY FELL APART. WE STILL HAVE THIS TRUCK, BUT THE ENTIRE UNDERSIDE OF IT (FRAME, SPRING HANGERS, FRONT DRIVE SHAFT, ETC) ARE ALL RUSTED. ANOTHER ISSUE THAT HAPPENED EARLIER THIS SUMMER - THE SPARE TIRE CARRIER HAD BECOME SO RUSTED, MY SPARE TIRE ACTUALLY CAME LOSE WHILE DRIVING DOWN THE ROAD. FORTUNATELY IT WAS HELD UP BY A CHAIN. UPON LEARNING THAT THIS IS A PROBLEM WITH MOST ALL GM TRUCKS, I FELT OBLIGATED TO BASE MY COMPLAINT IN THE HOPES THAT SOMETHING CAN BE DONE. TOYOTA FACED SIMILAR PROBLEMS, BUT FORTUNATELY STOOD BEHIND THEIR PRODUCTS AND MADE IT RIGHT WITH THEIR CUSTOMERS AND I FEEL GM SHOULD BE REQUIRED TO DO LIKEWISE. WE HAVE TRIED TO TRADE THIS TRUCK IN FOR ANOTHER VEHICLE, BUT ARE BEING OFFERED WAY BELOW KELLY BLUE BOOK PRICE BECAUSE OF THE RUST ISSUE. *TR

ELECTRICAL SYSTEM, SERVICE BRAKES
MY ABS CONTROL MODULE IS NOT FUNCTIONING PROPERLY. ABS IS DISABLED AND COSTS $1000 TO REPLACE. THIS IS A SAFETY HAZARD AS THE BRAKES CAN LOCK UP AT ANY MOMENT OR ABS IS DISABLED AND MAY CAUSE BRAKES TO LOCK UP. THE ABS LIGHT ON DASHBOARD IS ON CONTINUOUSLY AND THE MODULE WILL NEED TO BE REPLACED OR FURTHER DAMAGE WILL OCCUR. *TR

I WAS PARKING OUR 2004 GMC SIERRA PICK UP TRUCK WHEN MY FOOT WENT RIGHT TO THE FLOOR. AFTER GETTING OUT OF THE TRUCK, I NOTICED ALL THE BRAKE FLUID DRAINING OUT OF THE BRAKE LINE ON TO THE GROUND. WHEN OUR MECHANIC LOOKED AT IT, HE SAID ALL THE BRAKE LINES WERE RUSTED OUT AND THAT THE WHOLE UNDERCARRIAGE OF THE TRUCK WAS ENTIRELY RUSTED OUT. WHAT A DISGRACE. *TR
