What 447 owners told NHTSA about the 2014 GMC Acadia Denali

"SERVICE AIR BAG" LIGHT CAME ON. DEALER MADE WIRING REPAIR TO A SIR MODULE AND REPLACED A SIR SYSTEM SENSOR FOR APPROXIMATELY $530. IMMEDIATELY AFTER PICKING THE VEHICLE UP FROM THE DEALER THE "SERVICE AIR BAG" CAME ON AGAIN. THE DEALER WAS ABLE TO FIND A "BULLETIN" FROM GMC ADVISING TECHNICIANS TO CORRECT PROBLEM BY SOLDERING SOME ELECTRICAL CONNECTIONS. THIS APPEARS TO HAVE SOLVED THE PROBLEM. THIS SEEMS TO BE A SUBSTANTIAL DESIGN FLAW AND SERIOUS SAFETY ISSUE FOR A MISSION CRITICAL SYSTEM WHERE RELIABILITY IS PARAMOUNT. THIS PART DOES NOT ROTATE, IT IS NOT SUBJECT TO ANY UNKNOWN WEAR AND TEAR, THERE ARE NO PREVENTATIVE MAINTENANCE ACTIONS PROVIDED BY THE MANUFACTURER. IT ALSO APPEARS THAT GMC HAS NOT ADEQUATELY ADVISED THEIR DEALERS AND TECHNICIANS THAT THIS DEFICIENCY EXISTS AND WHAT THE PROPER CORRECTIVE ACTIONS IS WITHOUT EXORBITANT COSTS TO THE CONSUMER.

THE SERVICE AIR BAG SOON LIGHT IS ON AND THE CAR ONLY HAS 74,000 MILES AND HAS NEVER BEEN IN A WRECK. THIS IS THE SAME ISSUE THAT THERE WAS A RECALL FOR EARLIER MODEL YEAR ACADIAS UP TO 2013 AND IT IS WIDELY REPORTED THAT THE 2014S HAVE THE SAME ISSUE; THAT THE CONNECTOR HAS TO BE RESOLDERED FOR THE AIRBAGS TO DEPLOY. THIS IS A KNOWN SAFETY ISSUE TO GMC AND THEY ARE CHARGING APPROXIMATELY $400 TO FIX A KNOWN SAFETY ISSUE. NOW I'M GOING TO HAVE TO PAY $400 TO GET THIS FIXED BECAUSE IT IS NOT AN INCLUDED RECALL ON THE 2014S AND I DON'T WANT MY WIFE DRIVING A CAR WITHOUT AIRBAGS.

I'M GETTING SERVICE AIR BAGS ON MY 2014 GMC ACADIA. THERE WAS A RECALL ON AIRBAGS PREVIOUSLY FOR THIS VEHICLE FROM 2009-2013 BUT NOT THIS MODEL. I'VE READ ENOUGH COMPLAINTS ON THE AIRBAGS FAILING AND THIS IS A SAFETY CONCERN THAT NEEDS TO BE ADDRESSED. THIS CAR HAS NOT BEEN IN ANY ACCIDENTS OR FLOOD DAMAGE. THERE SHOULD BE NO REASON WHY I SHOULD BE GETTING SERVICE AIR BAG MESSAGE

ON ONE, APPROXIMATELY 200-MILE TRIP LAST YEAR, THE ELECTRICAL SYSTEM IN OUR ACADIA COMPLETELY WENT OUT (INCLUDING ALL GUAGES, TURN SIGNALS, ETC.) THREE SEPARATE TIMES. WE WERE DRIVING ON INTERSTATE ROADWAYS, AND THE VEHICLE COULD STILL BE DRIVEN. THE SYSTEM REBOOTED EACH TIME AFTER A FEW MINUTES. ULTIMATELY, MY WIFE ENDED UP STRANDED AS THE VEHICLE WOULD NOT START DUE TO ELECTRICAL SYSTEM FAILURE AFTER SHE HAD PARKED IT DURING A SEPARATE TRIP. OUR GM DEALERSHIP INFORMED US THAT THE REAR OBJECT DETECTION MODULES HAD CORRODED, AND THAT "EVERYONE HAS THIS PROBLEM." THE CORROSION CAUSED A CASCADE FAILURE OR THE ENTIRE SYSTEM, WHICH IS DEFINITELY A SAFETY HAZARD. GM REPLACES THESE MODULES WITH NON-CORRODING ONES NOW, AFTER WE PAID $992.52 TO HAVE THEM REPLACED. I CONTACTED AUTUMN AT GM CUSTOMER SERVICE, AND SHE SAID THAT THERE IS NOW SPECIAL COVERAGE FOR THIS PROBLEM THAT BEGAN ON 4/2/19. HOWEVER, OUR VEHICLE IS OVER THE 80,000-MILE WARRANTY FOR THIS PROBLEM.

SERVICE AIR BAG WARNING INDICATOR ON THE DASH. I'VE HAD MY CAR RIGHT AT A YEAR WHEN THE WARNING CAME UP ON THE DASH. UPON RESEARCHING I'VE NOTICED SEVERAL PEOPLE ARE HAVING THE SAME ISSUES AS CLOSE AS TWO DAYS AGO.. MY CAR HAS A LITTLE OVER 77,000 MILES ON IT.

I PURCHASED THIS VEHICLE USED IN APRIL 2017, BUT A FEW MONTHS AFTER I PURCHASED THE VEHICLE I STARTED HAVING A LIGHT ON IN THE DASH SAYING "SERVICE AIR BAG". I'VE TRIED IGNORING IT & HOPING THAT THERE WOULD EVENTUALLY BE A RECALL BECAUSE THE VEHICLE NO LONGER HAD A WARRANTY, BUT WE ARE ABOUT TO TAKE IT IN TO GET IT SERVICED. AFTER SEARCHING THE INTERNET I AM FINDING THAT MANY OTHER PEOPLE WITH ACADIAS HAVE HAD THIS SAME ISSUE & HAVE HAD TO TAKE THEIR VEHICLE & PAY TO GET IT SERVICED. I'VE ALSO READ WHERE THERE WERE SOME ACCIDENTS WHERE THE AIRBAGS DID NOT DEPLOY. I HAVE RESEARCHED ONLY TO FIND OUT THAT MANY GMC MODELS WERE RECALLED FOR THE SAME ISSUE, BUT IT WAS FOR YEAR MODELS PREVIOUS TO MINE (INCLUDING BUT NOT LIMITED TO THE YEAR BEFORE MINE). I HAVE A FRIEND WHO HAS THE CHEVROLET TRAVERSE (WHICH IS THE EXACT SAME VEHICLE AS MINE, JUST WITH THE CHEVROLET NAME) & SHE HAD THE EXACT SAME PROBLEM THAT I'M HAVING. IS THIS NOT A SAFETY ISSUE? PLEASE RESEARCH THIS. IT IS NOT COINCIDENCE THAT SO MANY PEOPLE HAVE HAD THIS PROBLEM! THIS LIGHT COMES ON AT ALL TIMES AS SOON AS YOU TURN ON THE CAR. I HAVE READ WHERE SOME HAVE HAD FAULTY WIRING UNDER THE SEAT THAT HAD TO BE RE-SOLDERED.

WHILE DRIVING, THE STABILITRAK SERVICE MESSAGE CAME ON, THEN TRACKTION CONTROL DISPLAYED. THE CAR THEN STALLED, WHILE DOING 70 ON THE FREEWAY. ALMOST GOT KILLED TRYING TO GET TO THE RIGHT LANE. HAD TO TURN OFF IGNITION (AND OPEN THE DOOR TO KILL THE ELECTRICAL CIRCUIT) TO RESET THE CAR TO DRIVE IT. THE CAR ALSO DOES THIS AT IDLE. IT WILL RANDOMLY MIS-SHIFT AND FEEL LIKE A CHAIN WAS HOOKED TO MY BUMPER AND BROKE OFF. SUPER SCARY, LIFE IN DANGER FOR SURE. THIS HAS HAPPENED 3 TIMES IN THE LAST 24 HOURS. I JUST BOUGHT THE CAR 5 DAYS AGO.

NHTSA ODI 11170701

MY VEHICLE WILL TELL ME TO SERVICE STABILITRAL, AND THAT TRACTION CONTROL IS OFF. IT INTERMITTENTLY DOES THIS AND GOES AWAY ONCE VEHICLE IS TURNED OFF AND BACK O. HOWEVER IT IS VERY DANGEROUS BC THE CAR THEN STALLS, HAS A HARD TIME ACCELERATING, AND HESITATES/STUTTERS AS IT TRIES TO ACCELERATE. MAINLY DOES THIS WHEN DRIVING MORE THAN 20 MILES ON HIGHWAY.BUT SOMETIMES IN CITY ENVIRONMENTS. IT SOUNDS VERY FAMILIAR TO ANOTHER RECALL. BUT IT DOES NOT APPEAR WITH VIN AS A RECALL
