SERVICE BRAKES, HYDRAULIC
I EXPERIENCE BRAKE PEDAL PULSATION (LOW SPEED ABS ACTIVATION) WHEN ROLLING TO A STOP. MY GMC ONSTAR REPORT SAYS THERE IS NOTHING WRONG WITH MY ABS BRAKING SYSTEM YET I HAVE THIS PROBLEM. THE PROBLEM SEEMS TO BE RUSTED AND/OR FROZE UP WHEEL SPEED SENSORS AS VERIFIED BY TWO DIFFERENT MECHANICS. I UNDERSTAND THEY WERE RECALLS BY GMC OF OTHER TRUCKS EXPERIENCING THIS SAME PROBLEM. I REALLY HATE TO PAY $750 FOR NEW FRONT WHEEL BEARING ASSEMBLIES. I WANT MY TRUCK RECALLED FOR THIS PROBLEM. THERE IS A GMC TECHNICAL BULLETIN 03-05-25-007D. I AM NOT SURE THE ABS WILL FUNCTION PROPERLY WHEN REALLY NEEDED?? *TR

VEHICLE SPEED CONTROL, ENGINE AND ENGINE COOLING
WHILE DRIVING ON THE HIGHWAY, MY 2003 GMC SIERRA 2500 DISPLAYED A "REDUCED ENGINE POWER" WARNING ON MY DASHBOARD. MY VEHICLE LOST ALL SPEED CONTROL, DECELERATING FROM 65 MPH TO 20 MPH IN A MATTER OF SECONDS. I IMMEDIATELY PULLED OVER TO THE SIDE OF THE HIGHWAY AND SHUT MY TRUCK OFF. ONCE I RESTARTED THE VEHICLE, THE MESSAGE WAS GONE AND MY TRUCK WAS FINE. IT WAS A VERY SCARY INCIDENT NOT BEING ABLE KEEP THE RIGHT SPEED FOR THE CONDITIONS ON THE HIGHWAY. *TR

LATCHES/LOCKS/LINKAGES, ELECTRICAL SYSTEM
MY 2008 GMC SIERRA DENALI'S AUTOMATIC LOCKS HAVE FAILED ON THREE OF THE FOUR DOORS. I DIDN'T REALIZE THEY WERE NOT ENGAGING UNTIL I TOOK TWO CHILDREN TO DINNER AND HAD ONE OF THEM OPEN THE DOOR WITHOUT UNLOCKING THE DOOR. I HAD THE CHILD SAFETY LOCKS ENGAGED AND THOUGHT I WOULD BE SAFE, BUT IT TURNS OUT THE LOCKS NEVER ENGAGED (THUS, MAKING THE CHILD LOCKS IRRELEVANT). THIS IS AN ISSUE BEYOND INCONVENIENCE. *TR

SERVICE BRAKES, HYDRAULIC, STRUCTURE:FRAME AND MEMBERS:UNDERBODY SHIELDS
BOTH THE DRIVER SIDE AND REAR BRAKE LINES, BECAUSE OF RUST, BURST AT THE SAME TIME. IT WAS LUCKY THE CAR WAS NOT ON THE ROAD.I HAVE REPLACED ALL THE LINES AND HAD TO REPLACE THE FRONT CALIPERS BECAUSE THE BLEEDING NIPPLED WERE COMPLETELY GONE DUE TO RUST. THE REAR CALIPERS WERE IN GOOD SHAPE.OVER THE COURSE OF OWNERSHIP, I HAVE HAD TO FORCEFULLY REMOVE THE TIRES FROM THE HUB BECAUSE THEY WERE RUSTED TO THE HUB. AGAIN I WAS LUCKY THAT I DID THIS WORK AT HOME AND WOULD HAVE BEEN IN SERIOUS TROUBLE HAD I BEEN FORCED TO CHANGE TIRES DUE TO A FLAT. IT ALSO APPEARS THE TRUCK FRAME IS SHOWING ADVANCE RUSTING FOR ITS AGE AND MILEAGE. *TR

MY BRAKE LINE FAILED ABOVE THE FUEL TANK, LOST PRESSURE TO THE BRAKING SYSTEM WHICH RESULTED IN NO BRAKES. WHY WOULD CAR MANUFACTURES USE STEEL BRAKE LINES THAT CAN ROT OUT VERY QUICKLY WHEN EXPOSED TO NORMAL DRIVING ELEMENTS. *TR

BRAKE LINES ARE SEVERELY CORRODED AND LOOK READY TO FAIL, AND I FIND OUT THAT THIS IS A COMMON COMPLAINT AND ALL THE BRAKE LINES SHOULD AND MUST BE REPLACED BY GENERAL MOTORS. THE GMC AND CHEVROLET 2500HD MODELS ARE NOTORIOUS FOR THIS MALADY, AND THE NTSB SHOULD DO THEIR JOB AND FORCE GM TO REPLACE AT NO CHARGE, THE VEHICLES BRAKE LINES. *TR

I WAS DRIVING ABOUT 35MPH AND I WAS COMING TO A RED LIGHT SO I PUT ON THE BRAKES AND I HEARD A POP AND MY BRAKE PEDAL WENT TO THE FLOOR AND I ALMOST WENT THRU THE INTERSECTION. I GOT OUT OF MY TRUCK AND SAW THAT I WAS LEAKING BRAKE FLUID FROM THE FRONT. I OPENED THE HOOD AND SAW MY FRONT BRAKE LINE WAS LEAKING AROUND A CORRODED AREA ON A HARD BRAKE LINE ATTACHED THE FRAME RAIL. IT WAS A HARD BRAKE LINE FAILURE NOT A RUBBER LINE LIKE IN THE WHEEL WELL. I CANT BELIEVE THAT A TRUCK THAT IS 12 YEARS OLD HAS A BRAKE LINE RUST THRU, THIS IS VERY DANGEROUS. *TR

STOPPED IN FRONT OF HOUSE AND WHEN ALMOST STOPPED THE BRAKE PEDAL WENT TO THE FLOOR AND I HAD NO BRAKES EXCEPT FOR A VERY SLIGHT "DRAG". I STOPPED AND LOOKED UNDER THE TRUCK AND SAW FLUID COMING FROM UNDER THE FRONT OF VEHICLE. IT APPEARED TO BE BRAKE FLUID AND IT WAS TRACED TO A METAL BRAKE RUNNING ACROSS THE FRONT FRAME MEMBER TO THE BRAKE ON THE FRONT PASSENGER WHEEL. THE LINE WAS EXTREMELY RUSTY AND LEAKING PROFUSELY. UPON FURTHER INSPECTION ALL METAL BRAKE LINES ARE SEVERELY RUSTED AND NEED REPLACED. I HAVE SEEN MANY VEHICLES BUT NONE WITH THIS AMOUNT OF RUST ON EVERY PART OF ALL LINES AND THE FRAME. THIS TRUCK IS 10 YRS OLD AND IS NOW UNSAFE TO DRIVE UNTIL ALL BRAKE LINES ARE REPLACED AT SUBSTANTIAL COST AND EFFORT. AS YOU WOULD EXPECT I AM NOT PLEASED BUT CONSIDER MYSELF VERY LUCKY. I COULD HAVE KILLED SOMEONE OR MYSELF. PLEASE WARN OTHERS THIS HAZARD EXISTS. *TR

NHTSA SHOULD BE OPENING INVESTAGATIONS CONCERNING THE BRAKE LINE CORROSION INCIDENTS. WE JUST PURCHASED THIS TRUCK LESS THAN A YEAR AGO, AND BRAKE FAILURE CAUSED US TO HAVE THIS IN THE SHOP FOR OVER A MONTH AND STILL HAVE NO TRUCK YET. THERE ARE ENOUGH COMPLAINTS ON THE INTERNET FOR THE NHTSA TO HAVE A RECALL BEFORE SOMEONE GETS KILLED DUE TO THIS PROBLEM. THIS TRUCK ONLY COST US 6000.00. REPAIRS WILL PROBALLY BE HALF THAT PRICE. *TR
