2002 GMC SIERRA Complaints

STEADY BRAKING PERFORMANCE DEGRADATION SINCE NEW, IN CONJUCTION WITH PREMATURE REAR BRAKE FAILURE @ 28000 MI (2.5 YRS OLD), WHILE FRONT BRAKES STILL HAD OVER 50% REMAINING PAD LIFE. DEALER STATED THAT REAR ROTOR RUST CAUSED REAR PAD FAILURE. INSPECTION OF REAR PADS INDICATE OTHER PROBLEMS-UNEVEN FRONT TO REAR WEAR ON LR INNER PAD .018" -.044", WHILE LR OUTER PAD HAD NO BRAKE MATERIAL LEFT. RR OUTER PAD HAD SLIGHT GROOVING ACROSS TOP WITH THICKNESS BETWEEN .110-.118", RR INNER PAD HAD GROOVING TOP AND BOTTOM, WITH BETWEEN .122-.151" THICKNESS PAD MATERIAL LEFT. *AK

WHILE MY 17 YEAR OLD SON WAS DRIVING, THE TRUCK SUDDENLY LOST ALL POWER STEERING AND BRAKE CAPABILITY. MY SON WAS TRAVELING WITH HIS YOUNGER BROTHER AND A FRIEND IN THE VEHICLE. *AK

I BROUGHT MY TRUCK TO MY DEALER BECAUSE THE PARKING BRAKE WOULD NOT HOLD. I HAD 30,000 MILES ON THE TRUCK AND HAD OWNED IT FOR 25 MONTHS. THE DEALER GAVE ME A RECEIPT SHOWING THEY HAD ADJUSTED THE BRAKE AND REPLACED THE CALIPERS & ROTORS. 12 MONTHS LATER I TESTED THE PARKING BRAKE AND IT WOULD NOT HOLD. I CALLED THE DEALER AND WAS INFORMED THAT THEY MADE A MISTAKE ON MY RECEIPT - THEY NEVER REPLACED ANY PARTS, THEY ONLY CLEANED THE PARKING BRAKE. I FOUND OUT THERE WAS A TECHNICAL SERVICE BULLETIN IN PLACE (02-05-26-001) WHEN I ORIGINALLY BROUGHT THE TRUCK IN UNDER WARRANTY BUT THE DEALERSHIP DID NOT REPAIR MY TRUCK ACCORDING TO THE TSB. THERE IS ALSO AN OPEN NHTSA INVESTIGATION (EA04011) ON THIS MATTER. I THINK THE DEALER SHOULD FIX THE PROBLEM AT THEIR COST. *AK

VEHICLE IS A 2002 GMC 6.0L 2500HD SIERRA TRUCK. IT HAS THE GM HYDROBOOST BRAKING SYSTEM (BRAKE ASSIST IS FROM THE POWER STEERING PUMP). THE PRESSURE LINE RUNNING FROM THE BRAKE BOOSTER TO THE STEERING RACK WAS INCORRECTLY ROUTED, RESULTING IN A VERY SHARP BEND IN THE FLEXIBLE PART OF HOSE. THE HOSE CRACKED AT THIS POINT, AND LEAKED SOME. THE FAILURE WAS CAUGHT EARLY, AND THERE WAS NO ACCIDENT OR FIRE. HOWEVER, IF THIS LEAK HAD NOT BEEN NOTICED, AT SOME POINT ALL POWER ASSIST BRAKING AND STEERING COULD HAVE BEEN LOST. I HAVE PICTURES OF THE INCORRECT ROUTING, AND THE OLD HOSE IF NEEDED.*AK

WHILE DRIVING FRONT SEAT WILL AUTOMATICALLY MOVE FORWARD, PINNING THE DRIVER AGAINST THE STEERING WHEEL. CONSUMER CONTACTED THE DEALER. HOWEVER, PROBLEM RECURRED. *AK.. THE OWNERS MANUAL TELLS HOW TO ACTIVATE THE MEMORY SETTING FOR FRONT SEATS., BUT IT DOESN'T TELL HOW TO DEACTIVATE IT. *AK

FRONT SUSPENSION/ STEERING 'RATTLES' EXCESSIVELY WHEN IN A TURN AND ROAD ROUGH TO THE POINT I MUST ACCOMMODATE IT IN HOW I DRIVEN TURNS. THE RATTLE ALMOST GOES AWAY AFTER THE FRONT SUSPENSION IS LUBED BUT IS BACK IN ABOUT 500 MILES OF DRIVING. *JB

THE DISC BRAKE PADS JAM AND FAIL TO MAKE PROPER CONTACT WITH THE ROTORS WHEN DIRT GETS IN THE AREA THAT THE BRAKE PADS RIDE ON 'RUNNERS (STAINLESS STEEL SHEET METAL COVERS THE MOUNTING FRAME WHERE IT RIDES . THE CLEARANCE IS SO CLOSE AND ROAD IT WILL JAM THE PADS. THIS REQUIRES DISASSEMBLY OF ALL OF THE BRAKE CALIPER AND GRINDING OF THE ROTOR FREQUENTLY. THE PADS NOT PRESSING ON THE ROTORS PROPERLY ALLOW THE ROTOR TO RUST FURTHER DEGRADING THE BRAKE PERFORMANCE AND CAUSES UNEVEN BRAKING AND GREATLY INCREASED STOPPING DISTANCE -- I HAVE HAD TO OVERHAUL THE BRAKES THREE TIMES AND THE REPAIR MECHANIC SAYS ALL GM TRUCKS HAVE THE SAME PROBLEM

WHILE PULLING VEHICLE INTO THE GARAGE THE STEERING AND BRAKES FAILED . AS A RESULT, VEHICLE COLLIDED INTO THE SIDE OF THE GARAGE.*AK

WHILE DRIVING WITH THE CRUISE CONTROL SET TO 70 MPH THE VEHICLE ACCELERATED TO 90 MPH WITHOUT WARNING. THE CONSUMER STATED SHE DISENGAGED THE CRUISE CONTROL, HOWEVER THE VEHICLE CONTINUED TO ACCELERATE. THE VEHICLE WAS THROWN INTO NEUTRAL IN ORDER TO SLOW IT DOWN. PLEASE PROVIDE ADDITIONAL INFORMATION. *JB *AK

THE DRIVER'S SIDE SEAT BACK FRAME FAILED AT THE WELDED JOINTS. DRIVER WAS THROWN TO RIGHT AND BACK WHILE AT HIGHWAY SPEED. THIS COMPONENT ALSO SERVES AS THE SHOULDER/SEAT BELT ATTACHMENT.*AK
