2006 Buick LaCrosse airbags problems
severe
Owners of the 2006 Buick LaCrosse have filed 29 NHTSA complaints about the airbags, typically surfacing around 63,000 miles at roughly $1,100 to repair (U.S. federal records, as of September 2026). Source: NHTSA Office of Defects Investigation.See airbags across all vehicles →
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
The 2006 LaCrosse's airbag system exhibits multiple distinct failure modes. The most commonly reported problem is the passenger-side occupancy sensor failing intermittently or entirely—sometimes failing to detect a seated passenger, causing the airbag indicator to turn off when it should be on. This happens at any temperature but is particularly pronounced below 55°F; owners report the sensor activating only after cabin heaters warm the interior. Sensor replacement has been attempted in several cases without resolving the underlying issue.
A second major complaint is an illuminated or flashing airbag warning light on the instrument cluster that dealers cannot diagnose or replicate, often with recommended repairs costing $1,000–$1,500 or more. Owners note that dealers sometimes claim the light is merely a display fault, yet diagnostic codes point to occupant sensing defects.
Less common but severe are two crash-related failures: airbags failing to deploy during actual collisions, and one documented inadvertent deployment of a curtain airbag as a passenger simply entered the vehicle while parked. One owner reports the VIN was excluded from NHTSA recall campaign 06V417000, suggesting incomplete remediation across the model line.

Failure modes owners describe
Passenger seat occupancy sensor fails in cold temperatures below 55°F
Passenger-side airbag sensor does not detect occupant presence at temperatures below 55°F, leaving the airbag disabled even when a passenger is seated. The sensor reactivates only after cabin temperature warms up.
When: Below 55°F ambient or cabin temperature; reported in January in Virginia
Symptoms owners cite: Airbag remains off despite passenger seated and bouncing in seat; Airbag indicator shows 'OFF' in cold conditions; Clicking sound heard when cabin warms and sensor activates
Recalls/TSBs owners mention: Dealers told owners this is normal operation
Passenger seat occupancy sensor works intermittently at any temperature
Passenger-side occupancy sensor fails to detect occupant presence intermittently regardless of temperature. The sensor may work normally for periods then randomly fail to activate the airbag for days or weeks at a time, even with the same passenger in the seat.
When: Intermittent; reported at various mileages (62,000 to 160,000) and temperatures (August 80°F); some ongoing since October 2015
Symptoms owners cite: Passenger airbag indicator does not light when passenger seated; Sensor works sometimes, fails other times with same passenger and conditions; On/off control on passenger side quit reading 'on' with passenger present; Airbag light goes off then comes on randomly while driving
Repairs/costs cited: Repair cost cited as $1,000 to $1,300; sensor replacement attempted but failed to resolve issue in at least one case; parts availability issues reported
Recalls/TSBs owners mention: Dealer stated that as long as airbag warning light is 'off,' all airbags are working; warned that if not fixed, airbags may deploy for no reason
Airbag warning light remains illuminated or flashes intermittently
Airbag warning indicator illuminates on the instrument cluster and either stays on continuously or flashes on and off intermittently while driving or parked. Diagnostic testing often points to sensor or occupancy module defects but dealers frequently cannot replicate or repair the issue.
When: Various mileages (26,000 to 160,000); reported in summer and cold months
Symptoms owners cite: Airbag warning light illuminated on instrument panel; Light goes off then comes back on randomly; Light flashes on and off repeatedly while driving; Light stays on continuously from vehicle start
Codes mentioned:Occupant sensing system defective, Air bag sensor/module failure in front passenger seat
Repairs/costs cited: Repair parts not available in some cases; sensor/module replacement recommended with costs reported over $1,500 in one instance
Recalls/TSBs owners mention: Dealers unable to diagnose; one VIN excluded from NHTSA Campaign 06V417000; manufacturer warned airbags could deploy inadvertently or fail to deploy in accident
Airbag fails to deploy in crash conditions
Airbag system fails to deploy during vehicle collisions when deployment would be expected. Reported in multiple crash scenarios including rollover at high speed and head-on crashes at moderate speeds.
When: At crash impact (documented mileages 26,000; speed-dependent incidents; one rollover with unknown mileage)
Symptoms owners cite: No airbag deployment during head-on crash at 30 mph; No deployment during high-speed rear-end with rollover; No deployment when vehicle accelerated uncontrollably and hit snow bank at 45 mph
Repairs/costs cited: Vehicles not repaired; police reports filed
Inadvertent airbag deployment during normal operation
Driver-side curtain airbag deployed without warning while vehicle was stationary in park position with passenger simply entering vehicle and closing the door. Occupant sustained head and neck injuries requiring medical attention.
When: While stationary in park; mileage approximately 110,000
Symptoms owners cite: Curtain airbag deployed with no crash or impact; Deployment occurred as passenger entered and closed door
Repairs/costs cited: Vehicle not diagnosed or repaired; towed to residence
Recalls/TSBs owners mention: Manufacturer notified but no follow-up documented
