A substantial cluster of complaints centers on the passenger-side occupancy sensor: owners describe the airbag OFF warning light staying on even when someone is sitting there, with the light flickering on and off when the passenger moves. Multiple owners paid $800–$1,700 to replace the sensor or occupancy module, only to find the problem returns or their VIN isn't covered under the available recall (07V062000). Dealers sometimes can't diagnose the issue at all.
Water intrusion is a recurring secondary cause of airbag faults. Owners report water pooling under the driver's floor and passenger floor during heavy rain, which leaks into the airbag module behind the glove box and damages floor sensors. One owner spent $3,200 on repairs and the water still came back.
On the deployment side, there are two troubling extremes: some owners report curtain and side airbags firing unexpectedly at low speeds on residential streets with no collision, while others were in real crashes—head-on at 50 mph, side impact at 55 mph—where the bags didn't deploy at all, leaving occupants injured. A few owners also report the service airbag light coming on repeatedly over years of ownership with dealers unable to pinpoint a cause despite multiple service visits. One owner documents an airbag deploying while attempting a jump-start with a dead battery and wet interior.
These are unverified consumer allegations with no manufacturer acknowledgment of systemic defects.
Same GMC Acadia airbags reports on nearby years: 2008 · 2009 · 2010
Passenger-side airbag light illuminates or sensor fails to recognize occupancy, causing airbag to deactivate when passenger is present. Sensor stops working or becomes erratic. Owners report intermittent on/off cycling when passenger moves or shifts weight.
When: Early in ownership; failure mileage range 6,000–93,000 miles reported
Symptoms owners cite: Passenger airbag OFF warning light illuminates continuously or intermittently; Airbag deactivates when passenger is in seat or moves; Service airbag message displays; Occupancy sensor unresponsive to passenger presence
Codes mentioned: B0081, Occupancy module code (erratic)
Repairs/costs cited: $800–$1,700 per owner reports for sensor/module replacement; dealer unable to duplicate on some vehicles
Recalls/TSBs owners mention: NHTSA Campaign 07V062000 does not cover all affected VINs; some owners told replacement is out of warranty; TSB exists for connector issues only, not module failure
Water leaks into vehicle interior, particularly through front windshield seal or sunroof drains, flooding footwells and contaminating airbag modules and floor sensors. Water damage triggers airbag warning light and requires costly replacement of sensors and modules.
When: Occurs during or after heavy rain; reported on vehicles 6+ years old with minimal prior water issues
Symptoms owners cite: Water pooling under driver floorboard or in passenger floor area; Airbag light illuminates after water intrusion; Wet interior carpets, moldy smell reported; Water leaking continues after repair attempts
Repairs/costs cited: $3,200–$4,200 for airbag floor sensor, module, and windshield replacement; water problem persists after repair in at least one case
Recalls/TSBs owners mention: No recall identified for water intrusion; dealer pinpointed windshield seal as source in one case but repair did not resolve recurrence
Side and curtain airbags deploy without collision impact while driving at normal speeds. Incidents occur on residential streets at 35 mph and on parkways with no contact with obstacles. Police and GM investigation found no reason for deployment; GM blamed operator error and excessive vehicle tilt, which owners dispute.
When: Occurs while driving at low speed; mileage not always reported
Symptoms owners cite: Curtain and/or side airbags deploy suddenly with loud noise and smoke; No impact or collision occurs; no potholes or debris found at scene; Vehicle does not tip or roll; All dashboard lights illuminate after deployment
Repairs/costs cited: No parts cited; vehicle typically towed to dealer after incident
Recalls/TSBs owners mention: GM denied liability and blamed operator error or excessive yaw (tilt >48°); no recall issued
Airbags fail to deploy during head-on or side-impact collisions at moderate to highway speeds. Occupants sustain injury from lack of restraint protection. One incident involved control module disconnected during impact; others lack clear cause.
When: Failure mileage 35,000–140,000 miles; no pattern of early or late failure
Symptoms owners cite: No airbag deployment during head-on collision at 50 mph; No airbag deployment during side impact at moderate speed; Occupants injured (head, chest, leg injuries reported); Vehicle sustains severe impact damage
Repairs/costs cited: Vehicle towed for inspection; one case found disconnected control module during impact
Recalls/TSBs owners mention: Manufacturer investigated and attributed one failure to control module disconnection during crash
Service airbag warning light illuminates intermittently or continuously without owner being able to determine cause. Dealer unable to duplicate or diagnose on many occasions. Light recurs multiple times over ownership.
When: Reported from 75,000–130,000 miles; some vehicles experience light within first year of ownership
Symptoms owners cite: Service airbag message displayed on dashboard; Warning light appears and disappears randomly; Multiple diagnostic visits unable to locate fault
Repairs/costs cited: Owners paid for multiple inspections ($500 reported in one case) with no resolution; dealer suggested possible loose connector in some cases
Recalls/TSBs owners mention: VIN not included in recall 07V062000; manufacturer unwilling to repair; no TSB covers root cause
Curtain airbag material splits or tears open while vehicle is parked. Warning light also illuminates. Indicates material degradation or manufacturing defect in airbag assembly.
When: Reported at 138,000 miles
Symptoms owners cite: Driver-side curtain airbag visibly splitting or tearing; Airbag warning light illuminates; Airbag not deployed in accident, yet material is compromised
Repairs/costs cited: Vehicle not taken to dealer; repair not performed

Symptoms owners cite: Passenger airbag OFF indicator illuminates with light-weight occupant (105–110 lbs) in seat; Airbag remains deactivated despite passenger presence; Dealer finds no fault upon inspection
Repairs/costs cited: No repair documented; dealer stated nothing was wrong
Recalls/TSBs owners mention: No response documented
Driver-side airbag deploys suddenly while owner is attempting to jump-start vehicle with completely discharged battery. Vehicle interior was wet from sunroof leak. No collision or impact occurred. Airbag deployed after turn of ignition key to OFF position while sitting in driver seat for less than one minute.
When: Occurs during troubleshooting of no-start condition; vehicle had been idle for weeks after alternator failure
Symptoms owners cite: Airbag deploys without collision or impact; Deployment occurs during jump-start attempt with dead battery; Vehicle interior wet from sunroof leak; Passenger airbag does not deploy (asymmetrical deployment)
Repairs/costs cited: No parts cited; owner documented incident with photographs
Recalls/TSBs owners mention: No response documented
Synthesized from 53 NHTSA owner complaints — unverified consumer allegations, summarized for patterns. The verbatim filings appear below.
Within 24 hrs of buying the vehicle my exhaust system fell off going down the highway. All the lights but the check engine light works on the dashboard. When you stop or accelerate the driver's seat moves forward or backwards slightly. Traction control does not work after the second week of owning it. When receiving for loaner vehicles all of them did not have working engine lights. *tr
Tl* the contact owns a 2007 GMC acadia. The contact stated that the air bag warning light illuminated and displayed that it was inoperative. The vehicle was taken to a dealer where it was diagnosed that the air bag module needed to be repaired. It was unknown if the vehicle was repaired. The manufacturer was not made aware of the failure. The failure mileage was 74,000.
Tl*the contact owns a 2007 GMC acadia. The contact stated that when someone weighing approximately 105 to 110 pounds sits in the front passenger seat, the air bag light illuminates. The illumination indicates that the air bag is deactivated. The vehicle has been taken to the dealer several times and they stated that nothing was wrong. The current mileage is 14,000 and failure mileage was…
The air bag light is on, when a diagnostic is done a code of B0081-OF shows up, which is passenger presence module erratic.
Passenger side air bag/ the defectiveair bag sensor in the passenger seat will not turn on the air bag when a parson is in that seat. The GMC dealer said the car is out of warranty, so will not fix the problem at no cost. I believe this is safety issue, GMC should repair this safty violation at no charge.
It's a meaningful issue. 53 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $1,100.
Across the 41 complaints that reported odometer mileage, most airbags failures cluster between 64,517 and 119,212 miles, with the median around 90,000. A quarter of owners report trouble before 64,517; a quarter make it past 119,212. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
Independent shops typically charge around $1,100 for airbags repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
