2015 GMC Acadia

WITHIN THE LAST WEEK, MY SERVICE AIR BAG LIGHT CAME ON AND THEN WOULD GO OFF, EITHER WHILE DRIVING OR SITTING. I COULD BE DRIVING DOWN THE ROAD, THE LIGHT WOULD COME ON, STAY ON FOR A MINUTE, GO OFF FOR A MINUTE AND COME BACK ON. IT DID THIS FOR SEVERAL DAYS. NOW THE SERVICE AIR BAG LIGHT STAYS ON ALL OF THE TIME. THE VEHICLE HAS NOT BEEN IN A CRASH.

SIDE BLIND ZONE SENSORS FAIL DUE TO WATER INTRUSION - WHICH IS A KNOWN ISSUE. A SPECIAL COVERAGE ADJUSTMENT (#N172097060) WAS ISSUED TO REPAIR THIS HOWEVER NOT ALL VEHICLES ARE COVERED IN THE SCA VIN SEARCH - AND ARE NOT BEING ADDRESSED. MY VEHICLE DID NOT FALL WITHIN THE VIN SEARCH AND EXPERIENCED THE SAME ISSUES DESCRIBED IN THE SCA. THE DAY AFTER THE INITIAL DIAGNOSTIC AND AWAITING THE PART FOR REPAIR I EXPERIENCED A COMPLETE VEHICLE SHUT DOWN DUE TO THE CORRUPTION OF THE SENSOR. I WAS NOT AWARE OF THIS SITUATION UNTIL AFTER I RESEARCHED THE SCA. THIS CORRUPTION IS NOTED IN THE SCA, HOWEVER IT ONLY STATES PART OF THE ISSUES YOU MAY SEE. DURING THE SHUTDOWN I WAS LUCKILY NOT IN MOTION, HOWEVER, THE CORRUPTION OF THE GMLAN CAUSE THE AIRBAGS TO DISABLE, PASSENGER AIRBAG PRESENCE DETECTION TURNED OFF, TIRE PRESSURE SENSOR MONITORS WERE DISABLED, THE ENTIRE DIC SHUT DOWN, INSTRUMENT CLUSTER SHUT DOWN, RADIO AND INFOTAINMENT CENTER SHUT DOWN, DOOR LOCKS MALFUNCTIONED, POWER STEERING SHUT DOWN, POWER BRAKES SHUT DOWN, WINDOWS WERE DISABLED, AND THE VEHICLE WOULD NOT RESTART UNTIL AFTER ABOUT 15 MINUTES. THERE IS NO PROTECTION BETWEEN THE SENSORS FOR ELECTRICAL INTERFERENCE AND THE GM LAN. A SENSOR SHOULD NOT CAUSE THESE ISSUES, HOWEVER IT DOES, AND IT WAS ALSO NOTED IN THE SCA. THIS ISSUE NEEDS TO BE ADDRESSED. THE MALFUNCTIONING SENSORS ALSO CAUSE A POWER DRAIN ON THE BATTERY, PRIOR TO THE DIC REPORTING THE SENSOR FAILURE, WHICH IS A FIRE HAZARD. GM HAS NOT ADDRESSED THE WIDESPREAD ISSUE OF THESE FAULTY SENSORS OUTSIDE THE SCA, NOR THE SAFETY HAZARDS OF THE LACK OF PROTECTION ON THE GM LAN CAUSED BY ELECTRICAL INTERFERENCE. IF THE VEHICLE IS REAR-ENDED, THE SENSORS COULD CAUSE CORRUPTION IN THE GMLAN SIMILAR TO THE WATER INTRUSION ISSUE - RENDERING THE FRONT AIRBAGS INOPERABLE.

MY 2015 GMC ACADIA HAS A SERVICE AIR BAG LIGHT ON. THIS VEHICLE HAS NEVER BEEN IN AN ACCIDENT OF ANY KIND (MINOR OR MAJOR). NOT SURE IF IT IS AN ELECTRICAL SHORT OR IF IT IS A BAD AIR BAG. NOW I HAVE NO IDEA IF THE AIRBAGS WILL EVEN DEPLOY IF WE ARE IN AN ACCIDENT. SINCE IT IS 3 YEARS OLD THE DEALERSHIP SAID THEY WILL NOT COVER IT UNDER WARRANTY. TO ME THIS IS A SAFETY HAZARD THAT SHOULD BE ADDRESSED WITH COST TO THE CONSUMER. I HAVE LOOKED FOR ANY RECALLS BUT HAVE NOT FOUND ANY. I'M SURE MY VEHICLE IS NOT THE ONLY ONE WITH THIS PROBLEM. CAN YOU PLEASE LOOK INTO THIS FOR THE SAFETY OF THE PUBLIC. THANK YOU

TL* THE CONTACT OWNS A 2015 GMC ACADIA. THE CONTACT STATED THAT THE SERVICE AIR BAG WARNING INDICATOR WAS ILLUMINATED. THE DEALER DIAGNOSED THAT THE AIR BAG WARNING SENSOR NEEDED TO BE REPLACED. THE AIR BAG WARNING SENSOR WAS REPLACED; HOWEVER, THE FAILURE RECURRED. WHILE THE VEHICLE WAS BEING REPAIRED FOR THE THIRD TIME, THE REAR AIR BAGS DEPLOYED INDEPENDENTLY. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 18,000.
