I HAVE A 2002 GMC SIERRA Z71 4X4 TRUCK, REGULAR CAB WITH AN 8 FOOT BED. IT HAS 75000 MILES. THE PROBLEM I'M HAVING IS BOTH OF THE OUTSIDE DOOR HANDLES STICK OPEN A LITTLE AFTER YOU PULL THE HANDLE TO OPEN THE DOOR AND GET IN. NOW WHEN YOU PUT THE TRUCK IN GEAR, OR START MOVING THE DOORS LOCK AUTOMATICALLY. WHEN YOU STOP AND PUT THE TRUCK IN PARK THE DOORS AUTOMATICALLY UNLOCK. NOW SINCE THE OUTSIDE DOOR HANDLE IS STUCK SLIGHTLY OPEN THE DOOR WON'T UNLOCK OR OPEN WITH THE INSIDE HANDLE, YOU HAVE TO REACH OUTSIDE PUSH THE HANDLE IN THEN YOU CAN UNLOCK AND OPEN THE DOOR. I HAVE ELECTRIC WINDOWS, AND HAVE TO PUT THEM DOWN TO RESET THE OUTSIDE HANDLE. MY CONCERN IS, IF I WAS IN AN ACCIDENT, AND MY WINDOWS WERE UP, AND MY BATTERY WAS DAMAGED, AND THE TRUCK LOST ELECTRICAL POWER I CAN'T OPEN THE WINDOWS TO RESET THE HANDLE, SO THAT I CAN GET OUT? NOW I'M TRAPPED IN THE TRUCK!! *TR

2002 GMC SIERRA, 84,000 MILES. DRIVER'S SIDE REAR METAL BRAKE LINE BLEW WHEN LEAVING A GARAGE AND I HAD TO USE THE EMERGENCY BRAKE TO STOP. IF IT WOULD HAVE HAPPENED A MINUTE LATER, I WOULD HAVE BEEN GOING DOWN A STEEP HILL INTO RUSH HOUR TRAFFIC, POTENTIALLY HURTING OR KILLING OTHERS OR MYSELF. THIS HAPPENED WITHOUT WARNING. MECHANIC SAYS ALL LINES SHOULD BE REPLACED DUE TO EXCESSIVE RUST. I DO LIVE IN PA, BUT I HAVE NEVER HAD A BRAKE LINE RUPTURE DUE TO RUST IN A NOT SO OLD CAR OR TRUCK. REGARDLESS OF THE COST TO FIX, THIS IS UNACCEPTABLE AND COMPLETELY UNSAFE. THERE ARE MANY OTHERS THAT HAVE THE SAME PROBLEM, AND MANY MORE WHO ARE NOT EVEN AWARE OF THE TIME-BOMB THEY ARE DRIVING. *TR

THIS WAS A 2002 GMC 1500 EXTENDED CAB PICK UP TRUCK WHICH WAS PURCHASED NEW IN 2003. IT TURNED OUT ALL BRAKES LINES ARE SEVERELY RUSTED AND NEEDED TO BE REPLACED. THIS TRUCK HAD 80,000 MILES ON IT AND HAS BEEN WELL TAKEN CAR OF. ALL LINES WERE REPLACED AT CONSIDERABLE COST. THERE WAS NO WARNING BEFORE THE INCIDENT. IT COULD HAVE HAPPENED AT 60 MPH. I ALSO OWN A 2003 GMC YUKON WHICH NOW APPEARS TO HAVE THE SAME PROBLEM. I WENT ON LINE AND FOUND MANY OTHER ANGRY OWNERS WITH THE SAME PROBLEMS. I HAVE BEEN DRIVING FOR 40 YEARS AND NEVER HAD THIS HAPPEN TO ANY OTHER CAR I OWNED. SOMEONE COULD GET KILLED!! *TR

1. ANTI-LOCK BRAKES ACTIVATION AT LOW SPEEDS 3-5 MPH. 2. ALWAYS THE FIRST TIME APPLIED WHEN COLD AFTER THAT AT VARIOUS TIMES 3. THIS IS THE SAME CONDITIONS AS NHTSA 05V379000 OR GM 05068 WHICH STARTED IN 2005. THE TRUCK WAS LOOKED AT THEN WHEN THERE WAS NO PROBLEMS BUT WHEN THE PROBLEM IS HAPPENING NOW GM SAYS THAT IT IS ONLY A ONE TIME RECALL. THE DEALER LOOKED AT THE TRUCK AND SAID THE HUB WAS WORN AND NEEDED REPLACED FOR $500 PER SIDE. WHEN I QUESTIONED THE SERVICE REP IF THE BEARING WAS WORN HE SAID NO. I THEN ASKED WHAT WAS WORN SINCE THE HUB IS THE BEARING. HE SAID I DID NOT HAVE TO HAVE IT REPAIRED IF I DID NOT WANT TO. I EXPLAINED THAT I WANTED THE RECALL WORK DONE WHICH WAS CLEANING THE RUST FROM THE SENSOR. I ALSO STATED THAT THERE ARE MAGNETS ON THE HUB THAT PASS THE SENSOR CREATING AN ELECTRICAL IMPULSE SO IF THE BEARING WAS NOT WORN ARE THE MAGNETS WORN? HE SAID THE HUB WAS BAD AND NEEDED REPLACED. I DECLINED THE WORK. I COMPLAINED TO GM AND THEY SAID THAT I WAS TOLD IT WAS A BAD SENSOR AND DECLINED THE WORK OR FURTHER DIAGNOSIS. THAT WAS A LIE. I THEN DID THE RECALL PROCEDURE OF REMOVING THE SENSOR AND CLEANING THE RUST AWAY. THERE IS ALSO NO BEARING PLAY SO THE HUB IS NOT WORN. THE BRAKES NOW WORK FINE. SO A COUPLE OF THINGS HERE. IF THERE IS A SAFETY RECALL AND IT COMES BACK AS THIS DID SHOULD THEY HAVE DONE THIS WORK. SECOND THE SERVICE DEPARTMENT AT JOE BALL GMC IS RUNNING A SCAM AND MAKING MONEY ON PEOPLE THAT DO NOT KNOW BETTER. *TR

ON OR ABOUT NOVEMBER 12 THE BRAKES ON MY 2002 GMC SIERRA 1500 PICKUP TRUCK FAILED SUDDENLY WHEN APPROACHING A STOP SIGN AND I PASSED THROUGH THE INTERSECTION, BEING UNABLE TO BRING THE VEHICLE TO A HALT IN THE DISTANCE AVAILABLE. WHILE THE INTERSECTION WAS CLEAR, AND NO ACCIDENT RESULTED, MY VEHICLE WAS COMPLETELY DISABLED. A LOCAL MECHANIC SAID THE BRAKELINE HAD FAILED - EVEN THOUGH THERE ARE LESS THAN 32,000 ON THE VEHICLE. HE SAID HE HAD SEEN SEVERAL FAILURES ON VEHICLES OF SIMILAR VINTAGE AND LIGHT SERVICE. REPAIRS COST OVER $900. GMC ASSUMED NO LIABILITY. *TR

DEAR SIR, I HAVE A 2002 GMC PICKUP THAT HAS HAD THE SPARE TIRE FALL OUT OF ITS MOUNT DUE TO SEVERE RUST OF THE FRAME. UPON FURTHER INVESTIGATION MY FRAME HAS SEVERE RUST IN SEVERAL OTHER AREAS. I HAVE CONTACTED GMC AND WAS BASICALLY TOLD TO HAVE A NICE DAY! I PURCHASED THIS VEHICLE NEW AND IT HAS 57,000 MILES TOTAL. MY BODY SHOP TELLS ME THAT THE ONLY WAY TO REPAIR THIS FRAME IS TO REPLACE IT! I FIND IT APPALLING THAT GMC SELLS A $40,000.00 VEHICLE THAT HAS A LIFE CYCLE OF 8 YEARS. I CANNOT SELL THIS VEHICLE TO ANYONE AND TRADEIN WOULD BE A JOKE. IS THERE ANY WAY YOU COULD MAKE GMC FACE THIS PROBLEM AND RESOLVE IT? EITHER REPLACE THE PICKUP OR FRAME? ANY HELP WOULD BE GREATLY APPRECIATED! [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

1. BRAKES WERE FULLY OPERATIONAL AFTER THE INITIAL RECALL WAS COMPLETED (10/13/05). RECENTLY, JANUARY 2010, MY ANTI-LOCK BRAKE SYSTEM HAS TRIGGERED AT LOW SPEEDS UNDER 10 MPH CAUSING MY TRUCK TO NOT COME TO A COMPLETE STOP. THIS IS THE SAME PROBLEMS I WAS HAVING PRIOR TO THE INITIAL RECALL. RELEASING THE BRAKES AND REAPPLYING THE BRAKES HAVE WORKED TO STOP THE VEHICLE SO FAR. 2. THE FAILURE HAPPENS ABOUT 1 IN 5 STOPS DEPENDING ON THE SPEED OF THE VEHICLE. I HAVE NEARLY HIT SEVERAL CARS IN PARKING LOTS, BECAUSE OF THE SLOW SPEED DURING PARKING. 3. GM HAD A RECALL 4 YEARS AGO ON THE WHEEL SPEED SENSOR (05V379000) ALL THEY DID WAS CLEAN AND LUBRICATE THE UNIT. NOT ADEQUATE ENOUGH, SINCE I AM HAVING THE SAME PROBLEM OVER AGAIN. *TR

ODI OPENED PE03-057 TO ASSESS PARKING BRAKE INEFFECTIVENESS IN THE SUBJECT VEHICLES.THESE VEHICLES ARE EQUIPPED WITH FOUR WHEEL DISC BRAKES THAT INCORPORATE A SINGLE-SHOE DRUM-IN-HAT PARKING BRAKE INDEPENDENT OF THE SERVICE BRAKES.COMPLAINT AND WARRANTY DATA INDICATE THAT THE PARKING BRAKE LININGS TEND TO WEAR OUT EARLY IN THE LIFE OF THE VEHICLE (AT AN AVERAGE OF 24 MONTHS IN SERVICE), REDUCING THE PARKING BRAKE SYSTEM'S TORQUE BELOW THAT NEEDED TO IMMOBILIZE THE VEHICLE.GM HAS ATTRIBUTED THIS ACCELERATED WEAR TO FOREIGN MATERIAL INTRUSION AND A FAILURE OF THE BRAKE SHOE TO PROPERLY SELF-CENTER WITHIN ITS BRAKE DRUM.EFFECTIVE WITH THE START OF MY 2003 PRODUCTION, A NEWER REDUCED FORCE HOLD-DOWN CLIP WAS INTRODUCED TO FACILITATE BRAKE SHOE DISENGAGEMENT FROM THE DRUM SURFACE.THIS PART IS ALSO AVAILABLE AT THE SERVICE LEVEL FOR THE MY 1999-2002 VEHICLES.GM HAS INDICATED THAT THE PAKING BRAKE IS INTENDED TO OPERATE IN CONJUNCTION WITH THE TRANSMISSION TO IMMOBILZE PARKED VEHICLES, AND THAT IN MANY CASES, ACCELERATED PARKING BRAKE LINING WEAR IS CAUSED BY ROUGH USE, VEHICLE MODIFICATIONS, AND DRIVING WITH THE PARKING ENGAGED. ODI HAS UPGRADED THE PRELIMINARY EVALUATION TO AN ENGINEERING ANALYSIS TO GATHER FURTHER INFORMATION CONCERNING PARKING BRAKE USAGE FACTORS AND THE CIRCUMSTANCES SURROUNDING THE SEVENTEEN REPORTED VEHICLE CRASHES.
