Should I buy a 2005 GMC Sierra with documented airbags problems?

Depends on the price and the specific vehicle. Documented airbags issues should be priced into the purchase — if the seller is asking full retail, negotiate down by the expected repair cost. A pre-purchase inspection from an independent shop tells you whether THIS specific vehicle has already shown the symptoms or not.

severe NHTSA 06V417000 October 31, 2006

Certain vehicles originally built with cloth seats that were equipped with an automatic air bag passenger sensing system and later reupholstered with aftermarket leather seat cover kits are involved

If the passenger sensing system malfunctions, the front air bag on the passenger side may be disabled when it should be enabled, or enabled when it should be disabled. In either case, in the event of a crash that requires air bag deployment, a front passenger's level of injury may be increased.

Fix: Because a replacement leather seat cover that is compatible with the passenger sensing system is not available, general motors (gm) will repurchase these vehicles in accordance with the terms stated in gm's letter to owners. The recall began on november 6, 2006. Owners should contact gm at 1-877-477-1022 to begin the process of repurchasing their vehicle.

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

Owners report two distinct airbag problems in 2005 GMC Sierras. First is the warning light: it comes on starting around 38,000–40,000 miles and continues appearing at intervals or staying lit permanently through 156,000 miles. Mechanics consistently diagnose airbag sensor failure—right front, left front, or seat sensors all fail. Replacement costs $300+ per sensor; owners replaced them again at higher mileages, indicating sensors are not lasting the vehicle's life. One owner replaced sensors three times over the truck's lifespan.

Second is airbag non-deployment in actual crashes. Three owners reported significant collisions—speeds from 45–60 mph, frontal impact, vehicle off embankment—where airbags did not deploy. One crash happened at 9,000 miles; another at 90,000. One owner sustained injuries when airbags failed to deploy during a highway accident. These are unverified allegations but serious: a safety system designed to fire in impact simply did not function when needed.

One owner reported unintended deployment—the driver-side airbag fired while the truck was shut off at 102,000 miles. A separate Takata recall (Campaign 15V324000) also affected some Sierras, though parts availability delayed repairs indefinitely at the time of complaint.

Failure modes owners describe

Airbag warning light illumination (sensor fault)

Airbag warning light comes on intermittently or stays on continuously, typically caused by airbag sensor failure or wiring faults. Owners report the light appearing at various mileages without any accident or impact.

When: Between 40,000 and 156,000 miles; one case at 38,000 miles

Symptoms owners cite: Airbag warning light illuminated on instrument panel; Light comes on intermittently then stays on continuously; Diagnostic scanners read 'OPEN FRONTAL LOOP'

Codes mentioned: Airbag sensor fault, OPEN FRONTAL LOOP

Repairs/costs cited: Right front airbag sensor replacement: $300+; left front airbag sensor: $100 (owner self-repaired); seat sensor recalibration: no charge reported

Recalls/TSBs owners mention: NHTSA Campaign 06V417000 (air bags) mentioned but vehicle VIN not included in recall

Airbag failure to deploy in crashes

Airbags did not deploy during impact collisions. Three separate crash incidents reported where airbags should have been triggered but failed to function.

When: Occurs at time of collision; mileage 9,000 to 90,000 miles

Symptoms owners cite: No airbag deployment during frontal or side impact collision; Vehicle struck at highway speeds (45-60 mph) with significant impact damage; Rear-end collision and vehicle-off-road incidents without airbag response

Repairs/costs cited: Vehicles not repaired; one vehicle was totaled and destroyed

Airbag sensor replacement necessity

Multiple sensor failures requiring replacement over vehicle lifetime. Owners report repeated airbag sensor faults at relatively low mileages for different sensors.

When: Multiple failures across vehicle life: first at 65,000 miles, second around 99,500 miles, third at 128,000 miles

Symptoms owners cite: Airbag warning light triggers; Diagnostic indicates airbag sensor failure

Codes mentioned: Right front airbag sensor fault, Left front airbag sensor fault, Seat sensor fault

Repairs/costs cited: Right front sensor: $300+; left front sensor: $100 (owner self-repaired); seat sensor: recalibrated no charge

Unintended airbag deployment

One case where driver-side airbag deployed while the vehicle was shut off, with no impact or accident condition present.

When: Approximately 102,000 miles

Symptoms owners cite: Driver-side airbag deployed without collision or impact; Deployment occurred while vehicle was turned off

Takata recall repair delays

Owners notified of airbag recall (NHTSA Campaign 15V324000, Takata-related) but replacement parts unavailable, resulting in extended wait times for recall completion.

When: Recall notification issued; parts unavailable as of complaint date

Symptoms owners cite: No actual airbag failure; recall notification received; Parts unavailable for recall repair; Manufacturer exceeded reasonable repair timeline

Repairs/costs cited: Parts not available for recall repair

Recalls/TSBs owners mention: NHTSA Campaign 15V324000 (air bags); GM Recall #49151 (Takata recall dated July 2016)
