What stands out
Airbags accounts for 32% of every owner complaint on file for this vehicle — the dominant problem area across 6 categories tracked.
No new NHTSA airbags complaint has been filed on this vehicle in over 13 years — the issue may be aging out of the active population.
In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.
Fix: Subaru will notify their owners and General Motors will notify Saab owners. Dealers will replace the passenger air bag inflator, free of charge. The Subaru recall began on June 17, 2015. Owners may contact Subaru customer service at 1-800-782-2783. The Saab recall began on July 27, 2015. Owners of Saab vehicles may call 1-800-955-9007. Subaru's number for this recall is WQR-53. Note: The recall completely supersedes recall 14V-399 (WQL-48) and partially supersedes recall 14V-763 (WQP-51) in that model year 2004 through 2005 Subaru Impreza and model year 2005 Saab 9-2x vehicles are now only part of this campaign. Note: On December 18, 2015 Subaru informed NHTSA of an expansion of this recall to include certain model year 2003-2004 Subaru Baja, 2003-2008 Subaru Legacy and 2003-2008 Subaru Outback vehicles.
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 overwhelming complaint across 21 narratives concerns the airbag warning light coming on intermittently or staying lit, which owners understand means the airbag system is disabled and will not deploy in a collision. Dealers consistently trace the problem to part #84621AG51A—the overhead map light assembly near the rear-view mirror—where faulty soldering or electrical shorts trigger a fault code 26 (passenger front seat system failure). Repairs run $200 to $389 and require replacing the entire overhead console assembly since no stand-alone airbag wiring part is available.
Several owners report the light cycles worse in cold or humid weather. One owner, whose airbag light was intermittent for about a year, lost consciousness while driving, hit two trees, and suffered a fractured vertebra and brain injury—the airbags never deployed. Owners note this is a known problem with many online complaints and forum discussions, yet Subaru classifies airbags as a "supplemental system" not covered by warranty, leaving owners to pay out-of-pocket.
Additionally, owners who received Takata passenger airbag recall notices faced months of delays waiting for parts that dealers claimed were coming "in a few weeks" but never materialized. No owner reports whether Subaru ultimately covered these recall repairs.

Failure modes owners describe
Overhead map light assembly electrical fault disabling airbag system
The map light/passenger seatbelt lamp assembly (part #84621AG51A) located on the interior roof near the rear-view mirror develops an electrical short or faulty soldering. Dealers report the fault triggers airbag warning light and disables the airbag system—airbags will not deploy during a collision when the light is on. The problem appears widespread across 2008 Legacy and 2009 Outback models.
When: Typically occurs between 59,000 and 110,000 miles; some owners report the issue starting shortly after ownership, intermittently worsening or becoming constant over time.
Symptoms owners cite: Airbag warning light on dashboard illuminates intermittently or constantly; Light may cycle on and off at random with no clear pattern; Condition may worsen in cold or humid weather; Light occasionally clears after restart but returns repeatedly
Codes mentioned:Fault Code 26 (passenger front seat system failure)
Repairs/costs cited: Replacement of entire overhead console assembly required; dealers report part #84621AG51A in stock. Owners cite repair costs ranging from $200 to $389.30 including labor. No partial airbag wiring replacement available; entire assembly must be replaced.
Occupancy sensor module failure
Passenger-side occupancy airbag sensor (sometimes identified as occupancy module) becomes defective, triggering airbag warning light. Dealers diagnose the sensor as the source, with the passenger airbag not deploying during a collision when the light is illuminated.
When: Occurs between 83,000 and 110,000 miles in reported cases.
Symptoms owners cite: Airbag warning light illuminates on instrument panel; Light may appear regardless of passenger occupancy in front seat; Intermittent triggering of warning light
Codes mentioned:Passenger airbag system fault
Repairs/costs cited: Replacement of occupancy airbag module or passenger-side airbag sensor required. Specific repair costs not cited in these narratives.
Takata passenger airbag recall parts shortage delaying repair
2008 Legacy owners received recall notices for Takata passenger airbags (NHTSA campaign 15V323000) but dealers unable to obtain replacement parts. Owners experienced delays of months or longer; dealers initially promised parts 'in a few weeks' but failed to provide timely follow-up or remedial transportation.
When: Recall notice issued December 2016; owners reporting ongoing delays through March 2017 and beyond.
Symptoms owners cite: Recall notice received for passenger airbag defect; Unable to schedule repair due to parts unavailability; Vehicle remains unrepaired for extended periods
Repairs/costs cited: Parts unavailable during recall period. Dealers stated parts would arrive 'in a few weeks' but failed to follow through.
Recalls/TSBs owners mention: NHTSA recall campaign 15V323000 issued for passenger airbag; parts shortage prevented timely completion. Dealers offered rental cars for some complainants but told others it was safe to drive pending parts arrival.

Airbag light keeps coming on and off. I took it to the dealership in january and spent over $100 to have them tell me nothing was wrong. Now it keeps coming on and off all the time as of july 2014 until now. This is a common problem and is something that should be covered because it is a safety requirement by law likes seatbelt. *tr
