2008 GMC YUKON DENALI XL Complaints

DRIVER SIDE POWER DOOR LOCKS WORK INTERMITTENTLY. HORN SOUNDS INDICATING DOOR IS LOCKED HOWEVER IT DOESN'T LOCK. ALSO REMOTE START DOES WORK LEAVING VEHICLE A TARGET FOR THEFT. ALSO THREE OF FOUR OF THE EXTERIOR DOOR HANDLES BROKE AND HAD TO BE REPLACED. *TR

DEFECTIVE DASHBOARD RESULTS IN CRAKING: THE DRIVER-SIDE CRACKS OCCUR TO THE LEFT OF THE INSTRUMENT CLUSTER, WHILE THOSE ON THE PASSENGER SIDE TAKE PLACE IN THE AREA SURROUNDING THE AIRBAG, CLOSER TO THE MIDDLE OF THE DASH. I CONCERN THAT A CRACKED DASH AT THE AIRBAG DEPLOYMENT POINT COULD BE A SAFETY HAZARD. *TR

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

STRONG GASOLINE FUMES LEAKING INTO THE VEHICLES PASSENGER'S INTERIOR OF A 2008 YUKON XL DENALI. IT OCCURS INTERMITTENTLY, BUT IS AN OVERPOWERING ODOR CAUSING NAUSEA AND DIZZINESS, AND PARTIAL BLACKOUTS OF DRIVER AND PASSENGERS. NO PROBLEMS EVIDENT. *TR

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

DOOR LOCK FAILURE. POWER LOCKS ON 3 OUT OF 4 DOORS HAVE FAILED WITHIN THE FIRST 30,000 MILES, UNDER NORMAL USAGE. OVER $600 TO REPAIR TWO DOORS, BUT FAILED AGAIN. THIS IS A POTENTIAL SAFETY HAZARD AS THESE DOORS CANNOT BE UNLOCKED AND THEN OPENED FROM THE OUTSIDE. *TR

2008 DENALI XL - DOOR LOCK FAILURES. 1ST REPAIR WAS UNDER WARRANTY @ 34000 MILES, REPLACED LEFT REAR DOOR LOCK. 2ND REPAIR WAS 8/4/10 FOR LEFT FRONT AND RIGHT REAR DOOR LOCKS REPLACED FOR $487.00 @ 40,000 MILES (OVER WARRANTY). DEALER EXPLAINED THAT MANY 2008 & 2009 GMC DENALIS HAVE BEEN COMING IN WITH DOOR LOCK FAILURES. THIS IS A SAFETY HAZARD AS YOU CANNOT UNLOCK THE REAR DOORS FROM THE OUTSIDE WHEN A CHILD IS IN A CARSEAT FOR INSTANCE. SHOULD BE A RECALL. *TR
