2008 GMC SIERRA Electrical System Problems

PURCHASED MY 2008 GMC SIERRA TRUCK IN NOVEMBER 2015 AFTER HAVING FOR ONLY 5 MONTHS DRIVER SIDE DOOR LOCK WILL ONLY LOCK OR UNLOCK SOMETIME, MAKING IT UNSAFE IF YOU NEEDED TO EXIT QUICKLY DUE TO ACCIDENT OR FIRE. SEEN MANY OTHER POST ABOUT SAME PROBLEM. SHOULD BE A RECALL ON THIS.

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

THIS IS NOT AN OFFICIAL COMPLAINT HOWEVER AS THE IGNITION PROBLEM UNFOLDS WITH THE GM PRODUCTS I WANTED TO TAKE THE OPPORTUNITY TO BRING TO THE ATTENTION A VERY SERIOUS PROBLEM THAT OCCURRED APPROXIMATELY A YEAR OR SO AGO WITH MY 2008 GMC SIERRA. I TYPICALLY PARK MY TRUCK IN THE GARAGE WITH THE KEY IN THE IGNITION. WE HAVE A LIVE CAMERA IN THE GARAGE AND ONE MORNING AROUND 7 AM AFTER A SEVERE THUNDERSTORM AROUND 3 AM I FOUND ON THE CAMERA THE TRUCK RUNNING WITH FLASHING HEADLIGHTS. I WENT TO GARAGE IMMEDIATELY AND WAS HIT WITH VERY HIGH HEAT DUE TO THE TRUCK RUNNING. WITH THE CARBON MONOXIDE POTENTIAL I DID NOT GO INTO THE GARAGE. I GOT MY WIFE'S KEYS AND TRIED A "REMOTE STOP" AND THE HEADLIGHTS STOPPED FLASHING BUT THE ENGINE CONTINUED TO RUN. I OPEN BOTH GARAGE DOORS AND WENT OUTSIDE SO I COULD ENTER THE GARAGE FROM THE OUTSIDE. I OPENED THE TRUCK DOOR AND BARELY TOUCHED THE KEY IN THE IGNITION AND THE TRUCK SHUT OFF. IT WAS NOT TURNED ON! WITHOUT A DOUBT IT HAD BEEN RUNNING ABOUT FOUR HOURS SINCE THE STORM. I CONTACTED GM AND WAS TOLD TO TAKE IT TO THE LOCAL DEALER. AFTER TELLING THE DEALER THE STORY THEY BASICALLY LAUGHED AT ME AND SAID THAT I WOULD HAVE TO BRING IT IN WHEN THE NEXT STORM CAME THRU. THEY LATER RUN A DIAGNOSTIC TEST AT GM REQUEST AND FOUND A MYSTERIOUS IGNITION CODE BUT NO SOLUTION. WHAT MAKES THIS EVEN STRANGER IS THAT WE ALSO HAD A 2010 YUKON THAT STARTED ON ITS OWN ONE AFTERNOON WHEN MYSELF, A SHERIFF DEPUTY AND THREE OTHER NEIGHBORS WERE STANDING NEXT TO IT DURING A SEVERE LIGHTNING STORM. THE GARAGE DOOR WAS OPEN, THE KEYS WERE "NOT" IN THE IGNITION BUT WHEN THERE WAS A LOUD LIGHTNING STRIKE IT STARTED.TO RUN. I DID NOT CONTACT ANYONE AND IT NEVER HAPPENED AGAIN UNTIL THE TRUCK STARTED AFTER A LIGHTNING STORM. I HAVE SINCE SOLD BOTH VEHICLES BUT THEY ARE STILL IN THE LOCAL AREA. I REALLY FEEL THE GM IGNITION PROBLEM GOES A LOT DEEPER!! *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

ON THE MORNING OF APRIL 11 WE HAD A SEVERE THUNDERSTORM AT APPROX. 3:00AM. LATER IN THE MORNING AT APPROXIMATELY 6:30AM I FOUND MY 2008 SIERRA TRUCK RUNNING IN MY GARAGE WITH THE GARAGE DOORS SHUT. THE HEADLIGHTS WERE FLASHING AND THE GARAGE WAS EXTREMELY HOT DUE TO THE ENGINE RUNNING. THERE WAS A LOT OF WATER CONDENSATION ON THE FLOOR INDICATING THAT THE ENGINE HAD BEEN RUNNING FOR QUITE SOME TIME. THE TEMPERATURE GAUGE WAS AT RUNNING TEMPERATURE. MY KEYS WERE IN THE IGNITION SO I OPENED THE GARAGE TO AIR OUT THE CARBON MONOXIDE AND TOOK MY WIFE'S KEYS AND TRIED TO STOP IT REMOTELY BUT IT WOULD NOT STOP. A FEW MINUTES LATER I WENT OUTSIDE AND CAME IN THRU THE GARAGE DOOR TRYING NOT TO BREATH THE FUMES. BY THEN THE TRUCK WAS NOT RUNNING. I FOUND THE CHECK ENGINE LIGHT ON. WHEN I TOUCHED THE KEY IN THE IGNITION THE CHECK ENGINE LIGHT WENT OUT. THE SEAT PRESETS WERE MESSED UP AND THE CLOCK WAS SEVERAL HOURS OFF. THERE WAS ABSOLUTELY NO WAY THE TRUCK WAS REMOTE STARTED. EVEN IF IT WAS IT SHOULD ONLY RUN FOR 10 MINUTES. THIS WAS A VERY SERIOUS AND DANGEROUS SITUATION! CONTINUING ON WITH A SIMILAR SITUATION A YEAR AGO, THERE WAS A SEVERE THUNDERSTORM COMING THRU. OUR NEIGHBORS HAD COME TO OUR HOUSE DURING THE WARNING SINCE WE HAD A BASEMENT. WE WERE ALL STANDING IN THE GARAGE WITH THE GARAGE DOOR OPEN AND OUR 2010 GMC YUKON STARTED UP LIKE SOMEONE TURNED ON THE IGNITION. THERE WERE NO KEYS IN THE IGNITION. THE ELECTRICAL STORM WAS ON-GOING WHEN THIS HAPPENED. WE SAW OUR NEIGHBOR LEAVE IN HER YUKON SO WE THOUGHT MAYBE SHE REMOTE STARTED HERS SO I FOLLOWED UP WITH HER TO SEE IF SHE HAD REMOTED STARTED HER CAR AND SHE HAD NOT. SHE TRIED TO REMOTE START HER CAR AND IT DID NOT AFFECT OURS WHATSOEVER. IT APPEARS THAT BOTH INCIDENTS SEEM TO BE STORM RELATED. IT IS A VERY SERIOUS AND DANGEROUS SITUATION KNOWING THIS COULD HAPPEN WHILE WE WERE ASLEEP OR AWAY FOR A FEW DAYS. *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
