What 447 owners told NHTSA about the 2014 GMC Acadia Denali

I was involved in an accident on 03/31/2022 I was only passenger. Going about 35 mph hit a parked vehicle on passenger side of vehicle. Side air bags employed. But front air bags did not. I did get a concussion and left with scar from embrasion above right eyebrow from hitting steering wheel. Why did not the front air bag go out?

The contact owns a 2014 GMC Acadia. The contact stated that the air bag warning light was illuminated. The vehicle was taken to the local dealer where it was diagnosed that the wiring in the seat was above the loophole. The vehicle was repaired. The manufacturer was notified but no additional assistance was provided. The failure mileage was approximately 105,207.

Twice in the past six months, the “Service Air Bag” warning light has come on. The first time, the wiring under the front passenger had to be resodered. Last week, the same warning came back on, and the wiring under both front seats had to be resodered. I feel this is a safety issue, and a design failure in this year and model car.

Service airbag light has been on since I’ve had the car. It was not covered by warranty (even though it is important?) in order to fix it I was quoted over $1000 which is ridiculous as I only had it a month before that and traction control became a issue. Warranty covered the traction but not the airbags.

I purchased my 2014 GMC Acadia Denali July 29th, 2021. It has been back to the dealer five times, with repairs not being completed. Within weeks of purchasing it, the Service Air Bag light came on, and won't go off. The low tire light came on. The serpentine belt broke and had to be replaced, and the power steering pump started making horrendous noises and leaking fluid. I bought an expensive service contract, and of course these repairs are not covered. I also had them repair tires twice, and ended up having to replace the two front tires, after being told there was nothing wrong with them, except one had a screw. They also said that tire rotation was causing the lights to go off, and wasn't reset, and supposedly they reset it to reflect where the tires are on the vehicle in relation to the TPMS's. Well, two tires lost air constantly, and there were numerous leaks. I finally took the vehicle to a real tire store for tire replacement. The estimate for the driver's side airbag system replacement is $1400 pre-tax, and the power steering pump replacement is $1100, pre-tax. So within two months, I've had nothing but trouble; spent $380 on two new tires, and will have the cost of these repairs on top of the extra $2200 I spent on a service contract. The vehicle is beautiful, and seemingly was well-maintained, but it immediately began breaking down. I've had very limited use of it since July 29th when I bought it. (it's now October 6th, 2021). I have a meeting with the owner of the dealership tomorrow, October 7th, at the suggestion of the dealership's repair manager, as well as the salesman.

The contact owns a 2014 GMC Acadia. The contact stated that while her son was driving 40 mph, the vehicle struck a curb and all the air bags deployed. The contact's son did not sustain any injuries. A police report was not filed. The dealer and manufacturer were not made aware of the failure. The failure mileage was 115,000.

Air Bag Service code shows up. It can be removed briefly by moving the seat back and forth. I did some research and this is similar to the recalls for older years previously issued with the wiring harness causing the air bags to malfunction. This is extremely dangerous and is well known on many car complaint sites. Why has nothing been done? Thank you.

I HAVE EXPERIENCED MY AIRBAG LIGHT GOING ON FOR THE LAST SEVERAL YEARS. DUE TO IT BEING OUT OF WARRANTY, I TOOK IT TO MY PERSONAL MECHANIC TO GET IT REPAIRED. IT TURNED OUT TO BE A HARNESS UNDER THE DRIVER SEAT. LESS THAN A YEAR LATER, IT HAPPENED AGAIN AND THIS TIME IT WAS THE HARNESS LOCATED UNDER THE RIGHT FRONT PASSENGER SEAT. THIS HAS BEEN REPLACED TWICE AND THE LIGHT HAS INTERMITTENTLY APPEARED AGAIN THE PAST 3 MONTHS

SERVICE AIRBAG NOTIFICATION REMAINS ON DUE TO UNREPAIRED SENSOR. I PAID THE DEALER ONCE TO MAKE THE REPAIR AND THE SERVICE NOTIFICATION CAME BACK ON A YEAR LATER, BUT THEY WANT TO CHARGE ME FOR THE REPAIR AGAIN. I HAVE NOT BEEN IN A MAJOR ACCIDENT SO I'M NOT SURE IF THE AIRBAGS WILL WORK. HOWEVER, THIS HAS BEEN A CONCERN. I PURCHASED THE VEHICLE BRAND NEW FROM THE DEALER AND THIS PROBLEM BEGAN WITHIN A FEW YEARS. HOWEVER, THEY REFUSE TO HELP ME WITHOUT CHARGING ME HUNDREDS OF DOLLARS.

"SERVICE AIR BAG" LIGHT KEPT COMING ON AND STAYING ON. TOOK TO DEALERSHIP WE PURCHASED FROM AND THEY TOLD US THE PROBLEM WAS UNDER THE SEAT AND HE RECONNECTED THE WIRES AND TOLD US IF IT HAPPENED AGAIN THAT THEY WOULD REPLACE IT. IT HAPPENED OVER AND OVER. IF YOU MOVE THE SEAT, IT WOULD TURN ON OR OFF. TOOK TO DEALERSHIP TO HAVE IT REPLACED BUT INSTEAD THEY TOLD US THAT WAS NOT THE PROBLEM THAT IT WAS IN THE DOOR. WE PAID THE $450.00 AND 7 DAYS LATER THE "SERVICE AIR BAG" CAME ON AGAIN. WE ARE TAKING IT BACK TOMORROW. THIS ISSUE, TO ME, IS A BIG SAFETY ISSUE. IF AN ACCIDENT OCCURS, AND THE AIRBAGS DID NOT WORK BECAUSE OF THIS NOT BEING FIXED CORRECTLY.... COULD CAUSE A DEATH. THIS BEGAN IN LATE 2019. IT COMES ON AT START UP, OR WHILE DRIVING DOWN THE ROAD. IT COMES ON ANYTIME AND HAS STAYED ON AND UNABLE TO CLEAR IT UNTIL WE FIGURED OUT TO MOVE SEAT AND IT TURNS ITSELF OFF, SOMETIMES.

SO WHEN I HAVE ONLY HAD THIS VEHICLE FOR TWO MONTHS NOW AND THIS MORNING WHEN I LEFT FOR WORK THE "SERVICE AIRBAG" LIGHT AND WARNING DISPLAY CAME IN Y. I HAVE ATTEMPTED EVERYTHING TO HAVE IT GO OFF THAT WAS RECOMMENDED BY OTHER ACADIA OWNERS. NOTHING HAD WORKED ...I HAVE READ SEVERAL COMPLAINTS ABOUT THE EXACT SAME THING AND FEEL THAT BECAUSE TO BE ADDRESSED BY GM. I DO NOT THINK THAT I ADD A SINGLE MOTHER AND GRANDMOTHER SHOULD BE OUT 590 TO 600 DOLLARS FOR SOMETHING THAT IS OBVIOUSLY A MALFUNCTION THAT GM CANNOT GET RIGHT. PERIOD IS IN THE PRIOR VEHICLES. *TR

AFTER START UP (WHILE DRIVING OR WITH VEHICLE AT REST) SERVICE AIRBAG NOTIFICATION POPS UP AND REMAINS ON DASH CENTER NOTIFICATION AREA ALONG WITH AIRBAG SYSTEM LIGHT ON DASH. DEALER WANTS OVER $1,000 TO REPAIR SOMETHING THAT SHOULD BE COVERED UNDER RECALL OR WARRANTY SPECIAL COVERAGE. THIS TYPE OF VERY COMMON OCCURRENCE SHOULDN'T BE LIMITED BY A 3 YEAR/36,000 MILE WARRANTY. OWNERS MANUAL STATES THAT AIR BAG MAY NOT DEPLOY. GM CUSTOMER SERVICE NUMBER CLAIMS THAT THE SYSTEM FAULT WILL NOT PREVENT AIR BAG DEPLOYMENT, BUT I WOULDN'T TRUST THAT GIRL ON THE PHONE TO BE ABLE TO CHANGE HER OWN WIPER BLADES, LET ALONE EXPLAIN THE FUNCTIONALITY OF THE AIRBAG SYSTEM. GMC NEEDS TO ISSUE A RECALL FOR THIS PROBLEM THAT PEOPLE ARE HAVING AT ALARMING RATES WITH THEIR 2014 GMC ACADIAS. THIS IS NOT LIMITED ONLY TO THE 2013 AND OLDER GMC ACADIAS. *TR

FIRST, 2 DAYS AFTER WE PURCHASED THE CAR, THE ENGINE LIGHT CAME ON. THEN THE FRONT CAMERA NEEDED SERVICE AND THE SIDE WARNINGS STOPPED. THEN THE SEAT HEATERS QUIT. THE FOBS BOTH QUIT WORKING, WOULD. IT PROPERLY UNLOCK THE DOORS. WE GOT AN AIRBAG NEEDS SERVICE WARNING. A CHECK GAGES WARNING. A SERVICE TIRE MONITORING SYSTEM WARNING. FINALLY, THE ENGINE LOCKS UP AND WON'T START, TURN OVER, OR ANYTHING. SEVERAL HOURS LATER, THE CAR STARTS. THEN IT GOES THROUGH THE WHOLE CYCLE AGAIN OVER THE NEXT FEW WEEKS TIL IT DOESN'T START AGAIN AND LEAVES US STRANDED. AGAIN. THE FIRST TIME, THE MCDANIEL GMC SERVICE DEPARTMENT CHANGED OUT THE BATTERY AND BELIEVED THAT WOULD FIX IT. WE PAID $190 FOR THAT. IT DIDN'T WORK. IT WENT THROUGH THE SAME CYCLE AGAIN WITHIN A MONTH. NOW THEY EXPECT US TO PAY TO HAVE HE MODULE FIXED, EVEN THOUGH THEY KNEW THERE WAS A RECALL FOR IT WHEN HEY SOLD IT TO US.

WHILE DRIVING, BOTH A SERVICE AIR BAG MESSAGE AND THE AIRBAG READINESS LIGHT ARE PERIODICALLY DISPLAYED ON THE INSTRUMENT PANEL AND DO NOT REAPPEAR WHEN THE ENGINE IS TURNED OFF AND BACK ON. AFTER A FULL DIAGNOSTICS CHECK COMPLETED AT THE DEALERSHIP, THE TECHNICIAN INDICATED THAT THE WARNING MESSAGES ARE DUE TO FAULTY CONNECTIONS IN THE WIRING HARNESS THAT NEED TO BE RE-SOLDERED TO ENSURE A PROPER CONNECTION.

WHILE DRIVING ON THE HIGHWAY GOING 65 MPH, ENGINE LIGHT CAME ON, THEN REDUCED ENGINE POWER ALERT. THE CAR WENT DOWN TO 8 MPH AND HARD TO STEER. I WAS BARELY ABLE TO PULL OFF ON THE SIDE WITHOUT GETTING HIT. TURNED OFF THE CAR (45 MINS) AS I WAS WAITING FOR MY SPOUSE AND WHEN I TURNED IT BACK ON, IT STARTED WITHOUT AN ISSUE. THE ENGINE LIGHT HAS COME ON A FEW TIMES AND THEN IT TURNS OFF ON ITS OWN. THE CAR HAS SHUT DOWN A FEW TIMES WHEN DRIVING SLOWLY - TURNING FROM A STOP OR IN DRIVE-THRU. TOOK IT TO THE AUTO REPAIR SHOP AND MECHANIC WAS UNABLE TO REPLICATE ISSUE AND FIND ANYTHING WRONG WITH IT. I ALSO GET THE AIRBAG SENSOR LIGHT TURN ON AND OFF RANDOMLY.

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

STARTED THE CAR ON A RAINY DAY AND THE AIRBAG LIGHT CAME ON AND A MESSAGE DISPLAYED "SERVICE AIR BAG". I TURNED THE CAR OFF AND STARTED THE CAR AGAIN AND THE MESSAGE AND AIRBAG LIGHT STAYED ON. I HAVE SEARCHED SEVERAL FORMS WHERE SEVERAL CONSUMERS ARE HAVING THIS SAME ISSUE.

NHTSA ODI 11269583

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.
