2008 GMC Sierra Interior & seats Problems

ALL FOUR DOOR LOCKS WERE INTERMITTENTLY INOPERATIVE & ONLY ABLE TO FUNCTION MANUALLY FROM THE INSIDE. TAKEN TO DEALER AND DIAGNOSED AS INTERNAL FAILURE IN DOOR LOCK ASSEMBLIES/ACTUATORS. ALL FOUR DOOR LOCK ASSEMBLIES WERE REPLACED AT A CUSTOMER COST OF $900+. THIS IS MY SECOND GMC VEHICLE THAT HAS HAD THE SAME PROBLEM AND AFTER SEARCHING THE INTERNET THIS SEEMS TO BE A FAIRLY COMMON PROBLEM. EVEN THE DEALERSHIP MECHANIC MENTIONED SURPRISE THAT IT HAS NOT BEEN RECALLED OR GMC HAS NOT BEEN FORCED TO FIX THE PROBLEM CONSIDERING HOW OFTEN HE HAD PERSONALLY DIAGNOSED & FIXED THIS SAME PROBLEM. THIS IS DEFINITELY A SAFETY ISSUE AS THE CUSTOMER IS UNABLE TO RELY ON THE DOOR LOCK SYSTEM OR LOCK/UNLOCK THE DOORS AS USUAL. MULTIPLE TIMES, MY VEHICLE SAT AT THE AIRPORT FOR DAYS UNLOCKED BECAUSE OF THIS FAILURE. SIMILARLY, MY TODDLER-AGED CHILDREN WERE ABLE TO OPEN THE DOORS TO THE BACKSEAT WITH THE VEHICLE IN MOTION DUE TO THE FAILURE IN THE AUTOMATIC ASSEMBLY. *TR

I HAVE TO LOCK AND UNLOCK BOTH OF MY PASSENGER SIDE DOORS MANUALLY, BECAUSE THE LOCKS DOESN'T WORK WITH THE KEY FOB NOR INSIDE THE VEHICLE. I FEEL LIKE THIS IS A SAFETY ISSUE THAT GM SHOULD RECOGNIZE BECAUSE SOMEONE COULD HAVE VALUES STOLEN OUT OF THEIR VEHICLES IF NOT HAVE THE VEHICLE STOLEN IF THEY FORGET TO MANUALLY LOCK DOORS WHEN THERE IS A PASSENGER IN THE VEHICLE. *TR

WE HAVE HAD THREE OF THE POWER LOCKS GO OUT - FIRST WAS FRONT PASSENGER, WHICH WAS UNDER WARRANTY AND COVERED FREE OF CHARGE, SO WAS THE SECOND - THE FRONT DRIVERS SIDE. BUT, THE REAR PASSENGER SIDE WENT OUT A YEAR LATER AND NOW THEY WILL NOT COVER IT UNDER WARRANTY. MY CONCERN IS THAT, HAVING SMALL CHILDREN, I HAVE HAD THEM LOCKED INSIDE THE VEHICLE AND THE UNLOCK DOESN'T WORK, SO I HAVE TO CLIMB THROUGH TO ACCESS THE DOOR LOCK. IN AN EVENT OF AN EMERGENCY, WHERE TIME IS OF ESSENCE - THIS IS A SEVERE ISSUE. *TR

ERRATIC DOOR LOCK BEHAVIOR. PASSENGER AND REAR DRIVER SIDE DOOR WILL NOT LOCK OR UNLOCK CONSISTENTLY. THE PASSENGER SIDE LOCK NOT LOCKING RESULTED IN THE THEFT OF A HANDGUN FROM MY VEHICLE. THIS DEFICIENCY LEAVES THE VEHICLE SUSCEPTIBLE TO THEFT, CARJACKING, DOORS COMING OPEN ON IMPACT. PASSENGERS, ESPECIALLY CHILDREN ARE AT RISK OF OPENING THE VEHICLE DOOR WHILE IN MOTION. IN THE EVENT OF AN EMERGENCY THE DOORS EFFECTED CAN NOT BE UNLOCKED FROM OTHER THAN THE MANUAL LATCH BUTTON TO AID PASSENGERS. *TR

MY CONCERN IS THREE DOOR POWER LOCKS HAVE GONE BAD AND REPLACED TWO SO FAR. MY CONCERN IS THE REAR DOORS ARE KEYLESS AND YOU CANT UNLOCK THEM FROM FRONT. I SPOKE TO GM AND THEY DON'T SEE A NEED TO RECALL TRUCK. I TALKED TO MY LOCAL MECHANIC AND GM DEALERSHIP AND THEY ARE SEEING A LOT OF FAILED POWER LOCKS ON THIS MODEL TRUCK. CAN I GIVE YOU A WHAT IF SCENARIO SAY THEIRS A FIRE IN FRONT AND I CANT UNLOCK REAR DOORS TO GET MY CHILDREN OUT WOULDN'T THAT BE A LIABILITY ISSUE IF I COULDN'T GET THEM OUT TO SAVE THEIR LIVES. *TR

PASSENGER DOOR LOCK STOPPED WORKING. ONLY WAY TO UNLOCK DOOR, IS BY REACHING ACROSS SEAT AND LIFT LOCK BUTTON. THIS IS UNSAFE IN CASE OF AN ACCIDENT, WHERE THE DRIVERS DOOR IS UNABLE TO BE USED FOR EXIT, AND THE PASSENGER DOOR MUST BE USED. *TR

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

ALL OF MY POWER DOOR LOCKS ARE NOT WORKING. THIS IS A VERY DANGEROUS SITUATION WHEN YOU HAVE CHILDREN IN THE BACK SEAT AND THEY TRY TO OPEN THE DOOR WHILE IN TRANSIT. I HAVE HAD THE LOCKS REPAIRED ONCE ALREADY WHILE THE TRUCK WAS UNDER WARRANTY AND NOW THEY ARE FAULTY AGAIN. THIS IS NOT WHAT I PAID FOR WHEN I CHOSE TO TRUST IN GMC. I THINK A LEMON LAW LAWSUIT IS IN ORDER IF THEY DON'T RESOLVE THIS ISSUE FREE OF CHARGE. GMC IS RISKING THE LIVES OF NOT ONLY MY CHILDREN BUT EVERY OTHER FAMILY THAT TRUSTED IN GMC. *TR
