What stands out
No new NHTSA airbags complaint has been filed on this vehicle in over 10 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.
15643A - Special Coverage. On some vehicles, equipped with power seats, the wire harness connector from the seat side airbag and buckle tensioner to the body has a design interference between the vertical adjust crossbar and the carpet. When the seat is moved forward or back, the connector may be dragged along the carpet, pulling terminals loose or pulling the connector apart. This will cause a diagnostic trouble code to be set and the service airbag light will be illuminated. Dealers will replace the affected harness connectors with accessory wiring harness components. The repairs will be made at no charge to the customer.

The failure pattern owners describe
The dominant complaint across these 10 narratives is an airbag warning light that comes on and off randomly while driving, with owners stating or inferring that airbags are disabled when the light illuminates. One dealer explicitly confirmed this risk. The light often resets temporarily if you adjust the driver's seat or turn the engine off and back on, but returns unpredictably. Three owners report diagnostic trouble codes pointing to loose connections and fretting corrosion in the driver's seat area (B0040, B0041, B0065); dealers have fixed it by unplugging the connector under the seat, cleaning it, and re-applying dielectric grease, but those fixes hold only temporarily before the light returns. One owner paid $120 for a dealer repair that did not resolve the issue. A separate complaint describes the passenger airbag light disabling for passengers under 150 lbs—the dealer's suggestion to add weight via a purse was offered instead of a sensor fix. One owner notes GM has a Technical Service Bulletin but it expires 10 years from the car's in-service date, limiting long-term remedies. The problem is reported as common on 2005–2013 Corvettes.

Failure modes owners describe
Intermittent airbag warning light with suspected non-deployment
Airbag warning light illuminates intermittently or persistently while driving, often in response to seat position changes or vibration. Owners report uncertainty whether airbags will deploy when the light is on; some dealers confirm airbags are disabled with the light active. Pattern reported across 2005–2013 model years.
When: Throughout ownership; some failures noted at highway speeds (35–45 mph)
Symptoms owners cite: Airbag warning light comes on and off randomly while driving; Light triggered by seat position adjustments; Light remains on after engine restart in some cases; Passenger airbag light turns off for occupants under 150 lbs; Airbag may not deploy with light illuminated
Codes mentioned: B0040, B0041, B0065
Repairs/costs cited: Unplugging and cleaning connector under seats temporarily resolves; one owner paid $120 with no permanent fix. Dealer added dielectric grease and re-mated connector; found frayed wire at seat belt, terminal fretting in X377 connector. Fixes often temporary—light returns.
Recalls/TSBs owners mention: TSB exists but limited to 10-year coverage from in-service date. GM has not issued universal recall or permanent fix. Some dealers suggest adding weight to passenger seat (disputed as ineffective workaround).
Passenger occupant classification sensor failure
Passenger airbag disabled (warning light off) when occupant weighs less than approximately 150 lbs, creating a safety gap for lightweight adults and children.
When: Occurs with passengers under 150 lbs
Symptoms owners cite: Passenger airbag warning light shows off when passenger weighs ~120 lbs; Airbag functional for passengers at or above 150 lbs
Repairs/costs cited: Dealer recommended passenger add weight via personal items (purse contents) rather than addressing sensor calibration.
