2008 GMC SIERRA 1500 Complaints

TL* THE CONTACT OWNS A 2008 GMC SIERRA 1500. THE CONTACT STATED THAT THE AUTOMATIC DOOR LOCK WOULD NOT LOCK EVEN WHEN ATTEMPTING TO LOCK THE VEHICLE MAUNALLY. THE VEHICLE WAS NOT INSPECTED BY A DEALER OR MANUFACTURER AND WAS NOT REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 38,000.

POWER DOOR LOCK FAILURE. CANNOT LOCK OR UNLOCK 3 OUT OF THE TRUCKS 4 DOORS WITH REMOTE OR THE ON BOARD LOCK/UNLOCK BUTTON. THE DRIVER DOOR FAILED 3 WEEK AGO, THE DRIVER SIDE REAR DOOR FAILED LAST WEEK AND THE PASSENGER SIDE READ DOOR FAILED YESTERDAY. THIS IS BOTH A SAFETY AND SECURITY ISSUE. THE BACK DOOR LOCKS CAN ONLY BE ACCESSED FROM INSIDE THE TRUCK IN THE EVENT OF AN EMERGENCY WITH NO KEY ACCESS. FROM A SECURITY STAND POINT THE FAILURE IS NOT KNOWN UNTIL THE DOOR EITHER DOES NOT LOCK OR UNLOCK AND YOU NOTICE THE FAILURE. THIS BECOMES AN ISSUE AS YOU MAY THINK THAT THE VEHICLES DOORS ARE LOCKED BUT THEY ARE NOT. ALSO THE INABILITY TO LOCK THE DOOR IN THE EVENT SOMEONE IS TRYING TO GET INTO THE VEHICLE I.E. CARJACKING. I HAVE SCHEDULED A REPAIR WITH THE DEALER WHO ADMITTED THAT THIS IS A KNOWN ISSUE. *TR

POWER DOOR LOCKS DO NOT WORK ON VEHICLE, WHETHER USING KEY FOB, OR LOCK/UNLOCK BUTTON INSIDE. THE PROBLEM IS INTERMITTENT; DIFFERENT LOCKS DO NOT WORK AT DIFFERENT TIMES. *TR

ENGINE CUTS OFF GOING DOWN THE ROAD IN MY 2008 GMC SIERRA. SERIOUS PROBLEM THAT IS HAD BY MANY OTHERS SINCE 2001...VERY DANGEROUS AND DUE TO A STICKY THROTTLE BODY ACTUATOR. *TR

BRAKE ROTORS WARPED AT 15K MILES, HAD THEM TURNED UNDER WARRANTY AT DEALER VEHICLE WAS PURCHASED FROM. AT 30K MILES ROTORS WARPED AGAIN, THIS TIME 1 BRAKE PAD WAS WORN DOWN TO 2MM THICK, THE REST APPEAR ALMOST NEW IN THICKNESS. DEALER TURNED ROTORS AGAIN AND REPLACED PADS FOR $200. REQUESTED AND WAS DENIED THAT THE BRAKE WORK BE COVERED UNDER WARRANTY BY DEALER AND GM CS. I TOOK OLD BRAKE HARDWARE HOME WITH ME AND STILL HAVE IT. I CONTEND THERE IS SOMETHING WRONG WITH THE DESIGN OR MATERIALS IN THE BRAKE SYSTEM OF THIS TRUCK CAUSING PREMATURE WEAR AND FAILURE OF "NON WARRANTY" BRAKE ITEMS SUCH AS THE PADS AND ROTORS. I CONTEND THAT THERE HAS BEEN A HANGING BRAKE PAD CAUSING THE ROTORS TO OVERHEAT AND WARP SINCE THE VEHICLE WAS NEW AND ANY WORK PERFORMED AT THE TIME OF THE 15K MILE ROTOR TURNING DID NOT CORRECT THE PROBLEM. IF BRAKE WORK NEEDS TO BE PERFORMED ON THIS TRUCK EVERY 15K MILES THERE IS A REASON THAT SHOULD BE COVERED UNDER WARRANTY. ONE TIME FREAK FAILURE I CAN SEE, TWO TIMES EVENLY SPACED AT 15K MILE INTERVALS AND I THINK SOMETHING IS WRONG WITH THE VEHICLES BRAKES DESIGN AND/OR MATERIALS. VEHICLE IS DAILY DRIVER, 15 MILES A DAY TO AND FROM WORK. GARAGED DURING THE WINTER, TAKEN OFF ROAD (FROZEN CORNFIELDS, DIRT FIELD ROADS) FOR A WEEK IN LATE FALL. USED TO TOW A FISHING BOAT A FEW TIMES A YEAR. OWNER IS A FORMER ASE CERTIFIED MECHANIC AND IS NOT AN AGGRESSIVE USER OF THE BRAKES. MEANING I BRAKE FIRMLY AND EVENLY WHEN BRAKING IS NEEDED, LIFTING MY FOOT OFF THE PEDAL ONCE STOPPED AND APPLY ONLY ENOUGH PRESSURE TO HOLD VEHICLE STILL. *TR

2008 GMC SIERRA 1500 TRUCK ELECTRIC LOCK ACTUATORS ARE DEFECTIVE - THERE ARE SEVERAL COMPLAINTS ON LINE - MINE ARE NO LONGER WORKING AND 2 OF THE 4 HAVE ALREADY BEEN REPLACED. *TR

RANDOM DOOR LOCK FAILURE LEADING TO PERMANENT FAILURE OVER SEVERAL MONTHS. OWNER IS UNAWARE OF PROBLEM UNTIL SEVERAL WEEKS OR MONTHS AS PROBLEM PROGRESSES TO COMPLETE FAILURE. DOOR LOCKS WILL SOMETIMES LOCK AND SOMETIMES UNLOCK, BUT TOTALLY UNAWARE TO THE OWNER UNTIL THE PROBLEM FINISHES WITH COMPLETE FAILURE. OFTEN TIMES VEHICLE IS LEFT UNLOCKED WHEN OWNER ASSUMES IT IS. THE PROBLEM CREATES OPPORTUNITY FOR CRIME AS WELL AS MANY OTHER SAFETY CONCERNS. THE OTHER MAJOR CONCERN IS THE INTEGRITY OF THE DOOR LOCKING SYSTEM DURING A CRASH ..... WHEN YOU KNOW YOUR DOORS MAY NOT BE LOCKED. I HAVE GRAVE CONCERNS FOR CHILDREN IN THE BACK SEATS OF VEHICLES THAT SHOULD BE LOCKED BUT AREN'T. BECAUSE OF FLAWS IN COMPONENT INTEGRITY. THIS PROBLEM HAS HAPPENED TO 3 (INCLUDING MYSELF) OUT OF 5 TRUCKS OWNED BY FRIENDS OR FAMILY MEMBERS. THE INTERNET IS FLOODED WITH THOUSANDS OF PEOPLE HAVING THE SAME PROBLEM. WE HAVE SERIOUS CONCERNS REGARDING THIS MATTER. THANKS FOR YOUR CO-OPERATION. *TR
