What 447 owners told NHTSA about the 2014 GMC Acadia Denali

MY HEADLIGHTS STOPPED WORKING WHILE I WAS DRIVING ON A HIGHWAY. I PULLED OFF THE ROAD & THE DRL LED LIGHTS AROUND THE HEADLIGHTS WERE STILL ON, BUT THE HEADLIGHTS WERE NOT. I TRIED TURNING THE LIGHTS OFF/ON, TRIED TURNING THE VEHICLE OFF/ON. MY HUSBAND CHECKED THE FUSES, RELAY, & SENSORS, AS WELL AS CHANGED BOTH BULBS AND THEY STILL WILL NOT WORK. IT WAS DARK WHILE I WAS DRIVING, WHICH POSED A DANGEROUS SITUATION. UPON RESEARCHING ONLINE, THERE SEEMS TO BE OTHER PEOPLE WHO HAVE HAD THE SAME PROBLEM.

WHILE DRIVING ON A CITY STREET THE 2014 GMC SIERRA 6.2 L V8 LOST POWER AND STARTED RUNNING ROUGH AS APPROACHING AN INTERSECTION. I WAS ABLE TO STOP, AND REVERSE THE VEHICLE AWAY FROM THE INTERSECTION, TO GET OUT OF TRAFFIC. THE ENGINE LIGHT WAS FLASHING AND THE TRUCK SHUT DOWN, IT WAS UNABLE TO RESTART. THE TRUCK HAD UNDER 60,000 MILES ON IT AT THE TIME OF THE FIRST INCIDENT. IT WAS TOWED TO A GM DEALER SHOP FOR REPAIR. THIS FIRST INCIDENT TOOK PLACE IN AUGUST OF 2019. THE ROCKER ARM AND EXHAUST SPRING HAD TO BE REPLACED IN THE #2 CYLINDER, THE CYLINDER HEAD HAD TO BE REBUILT WITH A NEW HEAD. IN ADDITION THEY REPLACED 4 FUEL INJECTORS. IN DECEMBER OF 2019, A SECOND INCIDENT HAPPEN WHILE DRIVING ON A CITY STREET, THE ENGINE STARTED RUNNING ROUGH, I WAS CLOSE ENOUGH TO MY HOUSE TO GET IT HOME, PARK IT AND IT WAS TOWED TO A A CERTIFIED GM DEALER SHOP FOR REPAIR.

SERVICE AIR BAG LIGHT HAS BEEN GOING ON AND OFF FOR A COUPLE WEEKS. AS OF 4 DAYS AGO IT HAS BEEN ON AND STAYED ON. I'VE BEEN TOLD THAT IT HAS SOMETHING TO DO WITH THE SENSOR IN THE SEAT AND FROM RESEARCH IT LOOKS LIKE THIS IS A VERY COMMON PROBLEM IN THIS VEHICLE

CAR WAS BANGING INTO SECOND GEAR PERIODICALLY SINCE THE DAY WE GOT IT AS A CPO ABOUT TWO YEARS AGO. THE DEALER SAID IT WAS NORMAL. FAST FORWARD TO LAST WEEK WHEN ALL OF A SUDDEN THE CAR WAS BUCKING AND SLAMMING INTO GEARS AND STALLING OUT AT LIGHTS. WE BROUGHT IT TO THE DEALER AND THEY SAID THAT THE CAR NEEDED A TRANSMISSION AND IT WAS OUT OF WARRANTY. GM CORPORATE DID NOTHING TO HELP WITH THE COST AND NOW I'M ON THE HOOK FOR A $6,000 BILL. PLUS I HAVE TO FIND A RENTAL CAR TO WAIT FOR THE BACK ORDERED TRANSMISSION TO ARRIVE BECAUSE OF THE STRIKE. NEVER AGAIN GM

MY "SERVICE AIR BAG" LIGHT AND WARNING CAME ON AND WE TOOK IT TO A MECHANIC WHO STATED IT IS THE WIRING UNDER MY DRIVERS SEAT CAUSING THE WARNING LIGHT. THE LIGHT FIRST CAME ON A FEW DAYS AGO WHEN I TURNED MY CAR ON AND WE HAVE SINCE DISCOVERED THE LIGHT WILL GO ON AND OFF IF I MOVE MY DRIVERS SEAT FORWARD AND BACK, BUT THIS IS A TEMPORARY FIX AS THE WARNING LIGHT STAYS ON IN THE SEAT POSITION I NEED TO KEEP IT IN FOR DRIVING. THIS IS THE SAME ISSUE AS THE RECALLED 2008-2013 GMC ACADIA. MINE IS A 2014 AND NOT A PART OF THE OFFICIAL RECALL, BUT CLEARLY THIS IS THE SAME ISSUE AND NEEDS TO BE RECALLED AND REPAIRED AT THE EXPENSE OF GM.

SERVICE AIG BAG LIGHT HAS ILLUMINATED. FROM THE RESEARCH I HAVE DONE, WHEN THIS OCCURS, IT DISABLES THE AIRBAGS FROM FUNCTIONING WHEN THE VEHICLE IS IN AN IMPACT COLLISION. IT APPEARS THAT THERE WAS A RECALL ON GMC ACADIAS FOR THIS ISSUE THROUGH THE 2013 MODEL. THIS IS AN ON-GOING ISSUE WITH THE ACADIA THAT RESULTS IN A POTENTIALLY LIFE THREATENING SAFETY FEATURE NOT WORKING.

THERE ARE HUNDREDS IF NOT THOUSANDS OF 2014 ACADIA OWNERS HAVING A SERVICE AIR BAG LIGHT COME ON AND WONT GO OFF. THERE WAS A RECALL FOR ALL ACADIA'S OF 2013 AND EARLIER THAT HAD A RECALL TO FIX THIS DANGEROUS ISSUE. 2014 NEEDS TO BE INCLUDED IN THIS RECALL. THIS IS A SAFETY HAZARD AND POSSIBLE DEATH UPON IMPACT ISSUE IF AIRBAG DOESNT GO OFF DUE TO GMC'S NEGLIGENCE IN DEALING WITH THE SAME ISSUE PREVIOUS MODELS HAD. GMC COULD FACE LAWSUITS IF SOMEONE IS KILLED DUE TO THIS ISSUE ON THIS YEAR ACADIA. ITS APPROX $500 TO FIX AND IS A CONSISTENT PROBLEM ACROSS MANY OWNED ACADIAS. MY CAR HAS NEVER BEEN IN AN ACCIDENT OR HAD THE AIRBAG DEPLOYED. THIS NEEDS TO BE DEALT WITH IMMEDIATELY.

ON SATURDAY EVENING AUGUST 3, 2019 MY WIFE, WHO WAS DRIVING OUR 2014 GMC ACADIA, REPORTED TO ME THAT A RED AIR BAG WARNING LIGHT AND THE MESSAGE "SERVICE AIR BAG" CAME ON AND REMAINED ON WHILE DRIVING. ON SUNDAY AUGUST 4, THE WARNING LIGHT AND MESSAGE WENT OFF DURING THE DAY WHEN I WAS DRIVING THE VEHICLE, BUT LATER CAME ON WHEN MY WIFE DROVE THE VEHICLE DURING THE EVENING. ON MONDAY AUGUST 5 WHILE I WAS DRIVING THE ACADIA, BOTH THE WARNING LIGHT AND MESSAGE "SERVICE AIR BAG" CAME ON AND STAYED ON WHILE DRIVING. ON MONDAY AUGUST 5 I DROVE THE ACADIA TO A GM DEALERSHIP AS SOON AS IT OPENED. THE DEALERSHIP SAID THERE WERE TWO DIAGNOSIS CODES FOR TWO SEPARATE FAILURES RELATING TO THE AIR BAGS. THE FIRST WAS CODE B0022 (WHICH THE DEALERSHIP SAID WAS RELATED TO A WIRING FAILURE). THE DEALERSHIP ADVISED THIS FAILURE CODE OF B0022 WAS COVERED UNDER WARRANTY PURSUANT TO GM SPECIAL COVERAGE ADJUSTMENT NUMBER 15804. THE DEALERSHIP SAID THAT THE SECOND DIAGNOSIS CODE WAS B0058 (WHICH THE DEALERSHIP SAID WAS A FAILED SENSOR). THE DEALERSHIP SAID THAT BOTH OF THESE PROBLEMS NEEDED TO BE FIXED IN ORDER FOR THE AIRBAGS TO WORK. THE DEALERSHIP SAID, HOWEVER, THAT REPLACEMENT OF THE SENSOR WAS NOT COVERED UNDER ADJUSTMENT 15804. THE DEALERSHIP DID OFFER A DISCOUNTED CHARGE FOR REPLACEMENT OF THE FAILED SENSOR AND AS OF THIS WRITING THE VEHICLE REMAINS AT THE DEALERSHIP TO MAKE ALL REPAIRS NECESSARY FOR THE AIR BAGS TO WORK. I HAVE ADVISED THE DEALERSHIP OF MY INTENTION TO REPORT THE SENSOR FAILURE ISSUE TO NTSB SO THAT NTSB AND GM ARE AWARE OF IT. I HAVE ALSO REPORTED THE ABOVE TO GM CUSTOMER ASSISTANCE AND AM AWAITING A RETURN CALL FROM A "SENIOR ADVISOR". I HAVE ALSO REQUESTED THAT GM COVER ALL COSTS RELATING TO THE SENSOR FAILURE AS WELL AS THE WIRING FAILURE AS I HAVE BEEN INFORMED BY THE DEALERSHIP THAT BOTH RELATE TO THE FAILURE OF THE AIR BAG SYSTEM.
