The 2010 Legacy has two distinct airbag problems documented in these complaints.
The first is a front passenger occupancy sensor that won't reliably detect adults weighing 80–135 lbs. The indicator light stays off or flickers erratically even when a normal-weight passenger sits in the seat, which means the airbag won't deploy if there's a crash. Owners submitted video evidence, had technicians verify the problem multiple times, and brought adults well above any threshold. Dealers and Subaru customer service blamed improper sitting posture and refused service. One Subaru field rep privately acknowledged the issue was real enough that he'd replaced the gel bladder in other cars with the same complaint, but management offered no recall. Tellingly, Subaru fixed this exact problem in the 2011 model—the 2010 owners bought a car Subaru already knew had a defect.
The second problem is driver-side airbag non-deployment in frontal crashes. Several owners experienced serious collisions that should have triggered deployment but didn't, leaving drivers with unprotected injuries including head trauma, lacerations, and a torn ACL from knee impact. Takata inflator recalls (campaigns 16V358000, 16V359000, 16V694000, 19V009000) affected many 2010s, but parts were unavailable for years, leaving owners unable to get the repair done.

Occupancy detection sensor for the front passenger seat fails to reliably detect adults weighing 80–135 lbs, causing the airbag indicator light to remain off or flicker unpredictably even when a passenger is seated normally. The sensor threshold appears set too high or calibrated incorrectly for smaller-framed adults. Subaru has acknowledged the issue internally—a field representative told one owner that a gel bladder replacement was required in similar cases—but dealers claim the sensor functions per design specification and attribute failures to improper seating posture.
When: Since purchase (2010 model year); ongoing throughout ownership
Symptoms owners cite: Airbag indicator light off or intermittently flickering on/off while passenger occupies seat; Light remains off despite passenger weighing 80–135 lbs (well above stated minimum thresholds); No deployed airbag in collision if light is off; Symptom persists across multiple driving conditions and vehicle states (parked, highway, city driving); Rebooting engine temporarily reactivates sensor but problem recurs
Repairs/costs cited: One field rep reported replacing gel bladder in seat; dealer recalibration and sensor 're-zeroing' attempts reported unsuccessful. Subaru has refused warranty coverage, citing design specification and improper seating as cause.
Recalls/TSBs owners mention: Subaru acknowledged internal awareness of the issue (2010 models). 2011 model year correction implemented. Field representatives conceded the problem exists but offered no recall or repair program. Subaru of America confirmed that if indicator light is off, airbag will not deploy in a crash. Dealers reported receiving multiple complaints but stated no corrective action available.
Driver-side airbag failed to deploy during frontal collisions with sufficient impact severity to require airbag activation. One incident involved a head-on collision with a utility pole causing total-loss damage; another involved a 55 mph frontal impact. Failure mechanisms unclear from complaints; post-incident inspections did not identify defects.
When: At various mileages (one reported at ~37,000 miles; others at unknown mileage)
Symptoms owners cite: No airbag deployment in frontal collisions meeting or exceeding deployment threshold; Driver subjected to unprotected impact injuries (head trauma, lacerations, knee injury, steering wheel contact); No warning light or system anomaly noted prior to crash
Repairs/costs cited: One owner underwent surgery for torn ACL and miniscus after knee struck steering wheel hard plastic; later received airbag recall with component replacement in steering column. Vehicles not diagnosed or repaired post-incident at dealership level.
Recalls/TSBs owners mention: Airbag recall campaign 16V358000 (passenger side) issued and included steering column component replacement. No clear manufacturer guidance or recall directly addressing driver-side non-deployment.
Multiple owners received NHTSA recall notifications (campaigns 16V694000, 16V358000, 16V359000, 19V009000) for Takata airbag inflators but could not obtain repairs due to prolonged parts shortages. Owners reported repair timelines extended months or years beyond initial recall notification. One owner reported dealership unable to schedule repair until October 2019, despite July 2019 recall request.
When: 2016–2019 recall period; parts still unavailable years after initial recall notification
Symptoms owners cite: Recall notification received but parts unavailable for repair; Dealerships unable to schedule repairs; manufacturer confirmed parts unavailable; Owners unable to use vehicles due to safety concerns
Codes mentioned: 16V694000, 16V358000, 16V359000, 19V009000
Repairs/costs cited: No repairs completed. Parts distribution bottleneck prevented implementation across multiple recall campaigns.
Recalls/TSBs owners mention: Subaru issued recalls 16V694000, 16V358000, 16V359000, and 19V009000 for Takata inflators. Manufacturer confirmed parts were unavailable and could not commit to repair timelines.
Airbag warning light illuminates intermittently. Dealer replaced airbag sensor multiple times (at least 4 visits documented), but failure recurred each time and could not be reliably duplicated for diagnosis. Issue began early in ownership and persisted across multiple repair attempts.
When: Early ownership (~150 miles); recurring through 4,000 miles and beyond
Symptoms owners cite: Airbag warning light illuminates at unknown intervals; Failure recurs after sensor replacement; Intermittent nature prevents consistent duplication for diagnosis
Repairs/costs cited: Airbag sensor replaced (multiple times); failures recurred. Dealer unable to duplicate recent failure for further diagnosis.

Passenger air bag light indicating air bag is off when a 5'4'' 112 pound adult female is in the seat. The indication light will sometimes flicker from off to on but mainly remains off for the duration of the drive regardless of the speed as well as when the car is in park. This incident has occurred since the purchase of the car in june 2011 and continues to occur each time my wife is in the…
The passenger-side air bag in our 2010 legacy is turning off intermittently and spontaneously while the car is in motion, although the passenger seat is occupied by a 120-pound person. The bag is deactivating even though the seat is securely locked into position as far from the dashboard as it will move, and nothing is placed beneath the passengers seat. To reactivate the air bag, it is…
Frontal driver's airbag did not deploy when automobile struck a utility pole head-on with sufficient force to damage it beyond economic repair. Only occupant was operator, and was using seatbelt but was injured due to force of impact against the steering wheel. Note 1: mileage is unknown. Figure supplied is an estimate. Note 2: photographs of the damage are available and the vehicle is…
Vehicle was involved in a front-end collision in which the Airbag failed to deploy. The vehicle has been considered totaled by the insurance company. A police report is available.
It's a meaningful issue. 25 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $1,100.
Across the 11 complaints that reported odometer mileage, most airbags failures cluster between 2,300 and 71,000 miles, with the median around 31,125. A quarter of owners report trouble before 2,300; a quarter make it past 71,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
Independent shops typically charge around $1,100 for airbags repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
