2008 GMC Yukon Denali Xl

DRIVING AT 70 MPH ON HIGHWAY. VEHICLE GAUGES BEGIN TO ACT ERRATICALLY, VEHICLE HEAVES AND LURCHES, THEN 100% POWER FAILURE. NOTHING WORKED, EVEN HAZZARD LIGHTS. AIRBAG LIGHT FLASHING ON AND OFF. WAS ABLE TO PUT VEHICLE IN NEUTRAL AND MOVE TO THE SIDE OF THE ROAD WHERE THE VEHICLE STOPPED. THERE WAS NO POWER AT ALL, HAD TO MANUALLY OPEN DOOR LOCKS. AFTER 10-15 MINUTES, THE POWER CAME BACK ON AND I WAS ABLE TO RESTART THE VEHICLE AND DRIVE HOME. HAPPENED AGAIN ON 3/23/14. AGAIN DRIVING AT HIGHWAY SPEEDS, THE ELECTRIC COMPONENTS (RADIO, GAUGES, POWER CORD ACCESSORIES) BEGIN ACTING ERRATICALLY AND THEN 100% COMPLETE POWER FAILURE WHILE DRIVING. THE GM DEALER CANNOT DUPLICATE OR FIND THE PROBLEM. I FEEL 100% UNSAFE IN THE VEHICLE ESPECIALLY WITH MY KIDS. *TR

TL* THE CONTACT OWNS A 2008 GMC YUKON DENALI XL. THE CONTACT STATED THAT WHILE DRIVING 55 MPH, THE VEHICLE STALLED AS THE CHECK ENGINE LIGHT ILLUMINATED. THE VEHICLE WAS TAKEN TO THE DEALER FOR INSPECTION WHERE THEY STATED THAT THERE WAS SOMETHING WRONG WITH THE OIL CONSUMPTION. THE VEHICLE WAS REPAIRED BUT THE CONTACT DID NOT KNOW WHAT WAS REPAIRED. THE FAILURE RECURRED AT 60,000 MILES. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 30,000.

THE 2008 GMC YUKON AND 2008 GM SUBURBANS HAVE A WIDESPREAD WELL-DOCUMENTED, REPEATED FAILURE OF THE DOOR LOCK ACTUATORS AS A RESULT OF A DEFECT WHICH GM WILL NOT ADDRESS VIA RECALL. I HAVE HAD TWO SEPARATE INCIDENTS OF FAILED DOOR LOCKS IN MY 2008 GMC YUKON. WHEN THE ACTUATOR FAILS, MY CHILDREN ARE ABLE TO OPEN THE CAR DOOR WHILE THE CAR IS IN MOTION. GM SHOULD BE RESPONSIBLE FOR THESE EXPENSIVE REPAIRS EVEN AFTER THE WARRANTY PERIOD EXPIRES SINCE THE DOOR LOCK ACTUATOR FAILURES ARE WIDESPREAD, COMMON (EVEN OCCURRING REPEATEDLY IN THE SAME CAR) AND CREATE A DANGER OF CHILDREN POTENTIALLY FALLING FROM THE CAR WHILE THE CAR IS MOVING. *TR

WAS WAITING FOR A RED LIGHT TO CHANGE AND SUDDENLY MY DASHBOARD LIT UP SAYING IT WAS REDUCING POWER TO THE ENGINE, DISABLING STABILITY CONTROL AND SOMETHING ELSE.. I WAS NOT ABLE TO DRIVE THE CAR FOR FOR 2 HOURS AFTER THAT... I.GOT THE CAR TOWED TO MY HOUSE AND WHEN I WENT BACK TO FALLOWING MORNING THE CAR STARTED WITH OUT THE ENGINE LIGHT ON..2 DAYS AFTER THE SAME THING HAPPENED WHILE DRIVING ON THE HIGHWAY AT 65 MPH, IT WAS A SCARY EXPERIENCE SINCE THE CAR REDUCED POWER VERY FAST TO 20 MPH.. ALMOST GOT INTO AN ACCIDENT. *TT

2008 GMC YUKON XL DENALI. DRIVER DOOR AND DRIVER SIDE REAR LOCKS FAILED. WITH AUTO LOCKS, THE LOCKS ON ALL DOORS ENGAGE WHEN THE CAR IS IN GEAR. GRANDDAUGHTER SITTING IN REAR SEAT IN BOOSTER WITH SEAT BELT. DRIVING VEHICLE, SHE PULLED ON DOOR HANDLE AND THE DOOR OPENED. STOPPED VEHICLE AND ATTEMPTED TO LOCK DOORS WITH BOTH KEY FOB AND INTERIOR SWITCH, NEITHER DOOR WOULD LOCK. ABLE TO LOCK DOORS MANUALLY. UNAWARE OF THE PROBLEM UNTIL INCIDENT. SHE COULD HAVE FALLEN OUT OF VEHICLE IF NOT FOR BOOSTER AND SEAT BELT. NO WARNING NOTED OR POSTED ON DRIVER INFORMATION CENTER. INCIDENTALLY, WHEN KEY FOB LOCK IS ACTIVATED, CAR ALARM IS ACTIVATED, HOWEVER DRIVER DOOR AND REAR DOOR ARE NOT LOCKED. VEHICLE DOES NOT REALIZE THIS AND REMOTE START FUNCTION STILL OPERATES. NOW CAR CAN BE STARTED, BUT ANYONE CAN JUST WALK UP AND DRIVE OFF IN THE VEHICLE, BECAUSE THE DOOR LOCKS ARE NOT FUNCTIONING. MOST CONCERN IS FOR SAFETY OF PASSENGERS, ESPECIALLY CHILDREN. THE AUTOLOCK DOORS WITH GEARS ENGAGED IS AN ADVERTISED SAFETY FEATURE. VERY DANGEROUS WHEN THIS SYSTEM FAILS...ESPECIALLY WITH NO WARNING LIGHTS TO INDICATE FAILURE. WOULD APPRECIATE A RECALL, OR AT THE VERY LEAST A WARNING TO OWNERS THAT THIS COULD OCCUR AND CREATE A HAZARD. *TT
