What stands out
No new NHTSA airbags complaint has been filed on this vehicle in over 9 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering airbags on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The 2012 Buick Enclave has two distinct airbag problems. The first—and more common—is the SERVICE AIRBAG dashboard warning. Owners describe the light coming on intermittently or staying lit continuously at speeds ranging from idle to highway, with no prior collision. The warning often appears shortly after purchase, sometimes within 48 hours of driving a used example off a lot. Dealers diagnose passenger-side airbag or passenger presence module failure, quoting repairs from $200 to $3,000; in at least one case, sensor replacement didn't fix it and the airbag itself needed replacing. Repair costs and diagnostic labor eat into owners' wallets while the system remains non-functional.
The second problem is real-world non-deployment. Multiple owners report side-impact and frontal collisions where all or specific airbags failed to inflate. One crash at 65 mph saw no curtain-airbag deployment, leaving occupants with head, neck, back, and shoulder injuries; another at 45 mph resulted in all airbags staying dormant, again causing head, neck, back, and arm injuries. A third collision injured the owner's head severely enough to break the window. GM Recall 14030 acknowledges that SIAB and front center airbags may not deploy in crashes, but parts are unavailable and not all VINs qualify for the recall, leaving owners driving vehicles with known safety defects.

Failure modes owners describe
SERVICE AIRBAG warning light illumination — intermittent or persistent
Dashboard warning light for airbag system comes on without prior collision or known cause. Light appears intermittent (flashing on and off) or stays on continuously. Occurs at various vehicle speeds or when stationary with ignition turned on. Owners report the light may appear, disappear within seconds, then reappear.
When: Reported from 62,000 to 109,000 miles; one complaint noted onset around 11-2016 at 78,000 miles; another at 61,000 miles shortly after purchase; several within 48 hours of used purchase
Symptoms owners cite: SERVICE AIRBAG message appears in message center; Airbag warning light illuminated on dashboard; Light flashes and then remains steady; Light cycles on and off repeatedly; Message appears for 8 seconds at a time; Warning occurs while driving or when parked
Repairs/costs cited: Passenger-side airbag replacement needed (quoted $1,100 in one case); passenger presence module replacement required; airbag sensors replacement attempted but did not resolve issue in one case; repair costs quoted at $200–$3,000 range depending on diagnosis; parts availability has been an issue under GM Recall 14030
Recalls/TSBs owners mention: GM Recall 14030 issued for SIAB (side airbag), front center airbag, and seat belt pretensioners that may not deploy in crash; parts availability delayed for this recall; dealers precluded from test drives or sale of Enclaves until recall resolved; GM confirmed cars are safe to drive despite safety notice; VIN-specific recall eligibility varies; some owners outside recall scope despite similar complaints
Complete airbag non-deployment during frontal or side-impact collisions
During actual vehicle crashes, airbags fail to deploy on impact. Incidents include frontal collisions at 45 mph, side-impact at 65 mph, and low-speed collisions (5–10 mph). Occupants strike vehicle interior, windows, and structures without airbag protection.
When: Mileage range 30,000 to 132,000 miles at time of collision; one complaint mentions prior failed brake event at 75,000 miles
Symptoms owners cite: All airbags or specific airbags (passenger-side curtain, front, driver-side) do not deploy; Occupants strike head, neck, shoulders on windows, interior structures; Severe head, neck, back, shoulder, and arm injuries across multiple occupants; Window breakage from impact with occupant head; Service dog injured in third row
Repairs/costs cited: Technician unable to diagnose failure in one case; vehicle salvaged in one low-speed collision case; vehicles not repaired due to diagnostic inability or total loss status; one vehicle remained unrepaired after dealer assessment
Recalls/TSBs owners mention: GM Recall 14030 addresses non-deployment risk for SIAB and front center airbag; manufacturer not notified in multiple non-deployment incidents; no recall issued for vehicles with documented non-deployment failures during complaints
Passenger-side airbag component failures requiring replacement
Passenger-side airbag system components (airbag unit itself or presence-detection sensor module) require replacement to resolve warning light or non-deployment risk. These are distinct component failures rather than sensor errors.
When: Diagnosed at 61,000 to 109,000 miles; one case had airbag sensors replaced but issue persisted, requiring full passenger-side airbag unit replacement
Symptoms owners cite: Airbag warning light illuminated; Dealer diagnosis: passenger-side airbag requires replacement; Dealer diagnosis: passenger presence module (seat weight sensor) requires replacement; All airbags disabled until repair completed
Repairs/costs cited: Passenger-side airbag unit replacement; passenger presence module replacement at $1,100 in one documented case; airbag sensor replacement ($200–$300) did not resolve fault in one vehicle; subsequent airbag unit replacement still pending in that case
Recalls/TSBs owners mention: No recalls specifically for passenger-side airbag or presence module failures in narratives; GM Recall 14030 does not address this component-level failure
Steering wheel airbag warning light without clear diagnostic path
Steering wheel airbag system triggers warning indicator. One narrative mentions steering wheel airbag warning alongside other structural concerns; limited diagnostic information provided.
When: Timing not specified in narrative
Symptoms owners cite: Steering wheel airbag warning light
Repairs/costs cited: No repair details provided

Last night (11/21/2016) my 2012 Buick enclave's passenger airbag light came on. Vehicle has only 61,000 miles. I took it in and found out that the passenger presence module needs to be replace at a cost to me of $1100. I was also told that air bags will not deploy in the event of a crash. I've noticed that this is an ongoing problem many people have with this car. How is this not a recall?
Frequent message appearing in the message center which indicates "service air bags'. The airbag symbol is also lit at the same time. The message appears at different times and will remain lit for about 8 seconds. It happens while the vehicle is in motion or when stopped, however not at any specific time. This vehicle was purchased new from the Buick dealer in el paso, texas and has never been…

During the crash, the passenger-side curtain air bags did not deploy. The driver sustained neck, back, and shoulder inquiries. The front passenger sustained head neck and back injuries. The second-row driver-side passenger…
