In late october, 2013, I purchased my 2006 GMC sierra c1500 standard cab, 2wd pickup from a private owner. On or about, december 01, 2013, I noticed that the "service air bag" warning message appeared intermittently. The "airbag" illuminated symbol in the dash instrumentation area was also illuminated. This would randomly come on and go off during normal operation of the vehicle. I…

What stands out
No new NHTSA airbags complaint has been filed on this vehicle in over 11 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: The 2006 GMC Sierra has documented airbag system failures ranging from warning light malfunctions that dealerships struggle to fix permanently to complete non-deployment during serious crashes. Some owners report parts that are no longer available from GM or any distributor, and at least one collision resulted in a fatality allegedly tied to airbag failure.
Owners of 2006 GMC Sierras report multiple airbag system failures. Most common is an illuminated service airbag warning light that cycles intermittently or stays on constantly. Dealership repairs have been unreliable—one owner had the light return permanently just weeks after a $600 parts replacement (driver seat position sensor and airbag control module). Diagnostic code P0084 appears in at least one case.
More serious are complete airbag failures during actual crashes. Owners report the front airbags did not deploy during high-speed frontal collisions, including a deer strike at 45 mph, a T-bone accident resulting in a fatality, a 65 mph guardrail impact, and a multi-vehicle highway collision requiring the driver to be cut from the wreckage. One owner also describes a front impact sensor (part # 10370150) that became non-functional and cannot be sourced from GM or aftermarket suppliers.
Finally, one owner reported both airbags deploying spontaneously while the vehicle sat parked and turned off, tearing apart the steering wheel and damaging interior trim.
No recalls or warranty coverage for airbag failures were mentioned by any owner.

Failure modes owners describe
Service airbag warning light illumination and intermittent cycling
Airbag warning light appears on dashboard and cycles on and off intermittently during normal vehicle operation, or illuminates constantly. Dealership attempts at repair provide only temporary relief.
When: Reported from late 2013 onward; one case at 111,000 miles, another at 120,000 miles
Symptoms owners cite: Service airbag warning message appears intermittently; Airbag warning icon illuminated in instrument cluster; Warning light cycles randomly during normal driving; Warning remains on constantly after initial dealer repair
Codes mentioned: P0084
Repairs/costs cited: Driver seat position sensor replacement and airbag sensing and diagnostic module replacement cited; parts cost approximately $600. First replacement attempt unsuccessful in one case; required two dealer visits.
Front impact (crash) sensor failure and unavailability
Front impact sensor (part # 10370150) becomes non-functional and is no longer available from GM or aftermarket distributors. This sensor detects rapid deceleration during frontal collision to trigger airbag deployment.
When: No specific mileage or timing provided in narrative
Symptoms owners cite: Front impact sensor no longer functional; Unable to obtain replacement part from GM or aftermarket sources
Repairs/costs cited: Part # 10370150 is unavailable for replacement; critical safety component with no alternative sources
Airbag non-deployment during frontal crashes
Front airbags fail to deploy during frontal impact collisions, including high-speed crashes and impacts with fixed objects. This is documented across multiple collision scenarios and resulted in serious injury or death.
When: Various mileages: 25,300 miles in one case, 103,000 miles in another, 120,000+ miles in others
Symptoms owners cite: Airbags do not deploy during frontal impact; Vehicle sustains severe frontal damage; Occupants suffer blunt force trauma, broken ribs, fractured bones, and in one case fatal injury
Unintended airbag deployment while vehicle parked and off
Both driver and passenger airbags deploy spontaneously while vehicle is parked and not running, causing structural damage to steering wheel, dashboard, and interior components.
When: No specific mileage provided
Symptoms owners cite: Both airbags deploy while vehicle is stationary and engine off; Steering wheel torn apart; Dashboard handle bent; Passenger-side vent cracked
