Of the 15 model years of Subaru Impreza we track for airbags problems, this one carries the most owner complaints on file — 91.
Airbags accounts for 38% of every owner complaint on file for this vehicle — the dominant problem area across 12 categories tracked.
If the ODS deactivates, the front passenger air bag will be turned off and the front passenger air bag will not deploy in the event of a crash, increasing the risk of injury to the seat occupant.
Owners report two main airbag system problems on 2012 Subaru Imprezas: intermittent passenger-side airbag deactivation with occupants in the seat, and broader SRS warning light malfunctions.
The most frequent complaint is the passenger airbag indicator switching to "OFF" while an adult is actively sitting in the seat—often while driving at highway speeds. This happens randomly, sometimes lasting minutes or longer, creating a genuine safety gap since the airbag may not deploy in a crash. The malfunction often clears after restarting the vehicle, but recurs unpredictably. Owners describe it happening 3–6 times monthly or more, sometimes during long drives, sometimes immediately after starting.
The underlying issue is a capacitive occupant detection system (ODS) that incorrectly triggers off. Owners note the sensor can be rendered unreliable by moisture (wet seats, damp clothing, snow gear), electronic devices nearby (cell phones, phone chargers in the 12V outlet), and seat movement. One owner documented gradual sensor degradation over 3–4 weeks after plugging in a charger; another described it turning off when detailing left the seat damp. Dealers have cited that the ODS is electrostatic-based, not weight-based, making it vulnerable to interference.
Subaru issued recall 15V-419 (WQT-55, NHTSA #15V419000) targeting certain build dates, but many owners whose cars exhibit identical symptoms fall outside the recall window or had the recall performed without resolving recurring failures. Parts shortages delayed recall completion significantly. Some owners report the replacement module itself fails, leaving them unable to use the passenger seat safely post-repair.

Passenger-side airbag indicator illuminates 'OFF' while an adult is actively seated, eliminating airbag protection in a crash. Occurs randomly, often during highway driving, typically resolves after vehicle restart but recurs unpredictably.
When: Intermittently, 3–6+ times monthly; commonly after 15 minutes–2+ hours of driving; no consistent pattern tied to speed or conditions
Symptoms owners cite: Passenger airbag light shows OFF despite occupant in seat; SRS/airbag warning light illuminates on dashboard; Condition clears temporarily after vehicle shutdown and restart; Reoccurs unpredictably during same drive or future trips; Occurs more frequently during long-distance highway driving
Codes mentioned: B1650, B1660, B16F0
Repairs/costs cited: Dealers replaced occupant detection system module, sensor mat, or entire seat bottom assembly. Quoted costs: ~$800–$1,300 for module/sensor replacement; ~$1,000 for full seat bottom replacement. Recall repair parts frequently back-ordered with no delivery timeline. Some owners report replacement modules subsequently failed with identical symptoms.
Recalls/TSBs owners mention: Recall WQT-55 (NHTSA #15V419000, issued August 2015) targeted 2012 Imprezas manufactured April 2011–February 2012. Subaru initially claimed sensitivity to moisture, electronic devices, and passenger weight, then acknowledged capacitive-sensing ODS design. Many out-of-window vehicles denied coverage despite identical failures. Dealers stated problem 'cannot be fixed unless actively occurring.' Recall parts severely delayed; dealerships ran out of inventory with no ETA.
ODS incorrectly activates the passenger airbag when a phone, small electronic device, or light object touches the seat, then fails to detect actual adult passengers. Indicates design flaw in capacitive-sensing technology.
When: Occurs intermittently; no clear trigger pattern
Symptoms owners cite: Passenger airbag light activates when lightweight objects (phone, laptop, charger) placed on seat; Same sensor fails to detect adult passengers in seat; System sensitivity appears inversely proportional to actual occupancy needs
Repairs/costs cited: One owner had sensor replaced under warranty September 2012. After replacement, the new sensor detected a cell phone on the seat but still failed to reliably detect actual passengers.
Recalls/TSBs owners mention: Subaru acknowledged the ODS uses electrostatic capacitive technology, not weight-based detection. Stated system is sensitive to electronic interference, moisture, and sweat. One dealer told owner sensor 'fails all the time' and is 'poorly designed'; noted newer model-year Imprezas no longer use this sensor type.
SRS/airbag warning light turns on at random intervals with or without passengers present. Light often clears after restart, but pattern is unpredictable and no consistent mechanical cause identified by dealers.
When: Occurs roughly 50% of the time vehicle is driven with a passenger; no consistent trigger
Symptoms owners cite: SRS/airbag warning light illuminates randomly on dashboard; Light appears with and without passenger present; Light may clear after vehicle restart; does not always clear; No identifiable mechanical issue found by dealer diagnostics; Can occur while parked or while driving
Codes mentioned: B1650
Repairs/costs cited: Dealers performed diagnostics but could not identify root cause. One dealer reset the airbag light and performed 'unknown repair,' but failure recurred. Another dealership stated they could do nothing because the warning light was off at the time of service.
Recalls/TSBs owners mention: Subaru stated the vehicle is 'working as designed.' Some dealers suggested the light cannot be addressed unless it is actively illuminated at time of service.
Occupant detection system fails after Subaru's recall repair (WQT-55) has been performed, with identical symptoms recurring. Suggests recall remedy was ineffective or replacement parts are also defective.
When: Occurs several months to years after recall service completed
Symptoms owners cite: Passenger airbag switches to OFF with occupant present, after recall repair already performed; Same intermittent deactivation pattern as pre-recall failure; Warning light recurs unpredictably; Multiple Subaru dealers report 3–4 other 2012 Imprezas with identical post-recall issue
Codes mentioned: B1650
Repairs/costs cited: Dealers quoted $800 module replacement or $1,000+ seat bottom replacement as the only solution, despite recall already being performed. One owner noted dealership said sensor 'fails all the time' and design is inherently poor. Replacement parts frequently unavailable or back-ordered.
Recalls/TSBs owners mention: Subaru declined to cover post-recall failures, stating vehicle was already serviced under the recall. One regional Subaru office told owner their vehicle manufacture date was just outside recall window and could not cover repair, despite identical diagnostic codes matching the recalled condition.
Passenger airbag falsely deactivates when the seat is damp or wet from detailing, rain-soaked clothing, snow gear, or spilled liquid. System recovers once seat dries. Indicates ODS is overly sensitive to electrostatic changes from moisture.
When: Occurs when seat is wet or damp; resolves after seat dries (hours to days)
Symptoms owners cite: Passenger airbag indicator switches to OFF immediately when damp passenger sits; Airbag light illuminates with false OFF status; Condition persists while seat is wet or damp, regardless of vehicle speed or motion; Problem resolves once seat dries completely
Repairs/costs cited: No repair required; condition is self-resolving upon drying. However, represents a serious safety gap: if a collision occurs while seat is damp, airbag will not deploy.
Recalls/TSBs owners mention: Subaru and dealers acknowledged moisture is a known trigger. Subaru stated the ODS is sensitive to moisture and sweat, and confirmed the airbag may not activate during a collision if this condition exists. One service representative claimed this is 'normal' behavior for the system.
Passenger airbag switches to OFF when electronics (phone chargers, laptops, cell phones) are plugged into or placed in the vehicle, even with an adult in the seat. Indicates the electrostatic-capacitive ODS is susceptible to electromagnetic interference.
When: Occurs when electronic device is plugged in or located near passenger seat; resolves when device is removed
Symptoms owners cite: Passenger airbag light switches to OFF when charger is plugged into 12V outlet or electronics are in the seat; Airbag reactivates when electronics are removed; Occurs with multiple charger types and electronic devices; One owner documented gradual sensor degradation (3–4 weeks) after plugging in iPhone charger
Codes mentioned: B1660, B16F0, B1650
Repairs/costs cited: Temporary workaround is to avoid plugging devices into the 12V outlet or placing electronics near the passenger. Permanent fix requires ODS module or sensor replacement ($800–$1,300).
Recalls/TSBs owners mention: Dealers and Subaru confirmed the ODS is electrostatic capacitive and sensitive to electronic pulses from chargers and devices. Subaru stated electronic pulses can render the airbag ineffective during a collision. One dealer recommended avoiding use of electronic devices in the vehicle.
Subaru issued recall WQT-55 in August 2015, but replacement ODS modules were unavailable at dealerships immediately and for months after recall notification. No estimated delivery dates were provided, forcing owners to delay repairs on a safety-critical system.
When: Occurred throughout recall period (at least August 2015–September 2015 and beyond); one owner reported parts unavailable in 2019
Symptoms owners cite: Appointment scheduled for recall repair, but parts not in stock; Owner waited 1+ hour for service only to learn repair could not be completed; Dealership requested customer call when part arrived; no followup occurred; Over one month elapsed between recall notice and parts availability; Multiple Bay Area dealerships reported parts on back order with no ETA; Owner received cancellation email with no indication of when repair could be rescheduled
Repairs/costs cited: None—repairs could not be completed due to parts shortage.
Recalls/TSBs owners mention: Subaru indicated parts were back-ordered but did not provide realistic timelines or proactive communication. Recall notice implied parts would be available for immediate repair, which was not the case. One owner reported Subaru corporate declined to provide a loaner vehicle during the delay.
In at least one documented case, the frontal airbags failed to deploy during an actual crash impact. Investigation found fractured airbag wiring; owner sustained head injury and left-arm injuries requiring medical attention.
When: Approximately 69,000 miles
Symptoms owners cite: During left-turn collision, frontal airbags did not deploy; Vehicle struck on front driver side; Owner suffered head injury and left-arm injuries
Repairs/costs cited: Post-crash inspection revealed fractured airbag wiring. Vehicle was towed and destroyed.
Recalls/TSBs owners mention: Subaru was not notified of the failure.

Passenger airbag randomly turns off when passenger is in the car. Took to a dealer and they couldn't repeat. Was told it was probably just a weight issue. If the airbag doesn't go off with a passenger there it could be fatal. *tr
On 2 separate occasions airbag warning light on dash lit and airbag light stated passenger airbag was off despite seat being occupied..Subaru states cant find issue but I have a pic of the warning light on(looks like pregnant women!!). Worried car /airbag unsafe. *tr
Passenger air bag light turns from on to off with a passenger sitting there. Manual says this happens when there is moisture in the seat. First of all, the airbag should not turn off for that reason, that is a safety problem. Second, it turns off even when there is no moisture. It scares me. I need to know that the airbag is still working even if that off light is on if my son is sitting…
When driving with a passenger the air bag for the passenger will not turn on and dashboard lights will come on.
Tl* the contact leases a 2012 Subaru impreza. While driving approximately 35 MPH, the front passenger air bag warning lamp illuminated even though there was an occupant in the front seat. The dealer stated that the jumper cables under the passenger seated resulted in the sensor not operating properly. The vehicle was not repaired. The manufacturer was not made aware of the failure. The…
Front passenger seat airbag sensor gradually stopped working. This seat sensor had allegedly been checked and fixed in 2015 as part of Subaru voluntary recall subsequent to the NHTSA investigation. At that time, the sensor was working properly; the nature of Subaru's fix is unclear. Since the voluntary recall, the front passenger seat has not been modified. There has been no water spill. The…
It's a meaningful issue. 91 complaints have been filed and the failure mode causes operational problems for owners. Repairs average $1,100.
Across the 72 complaints that reported odometer mileage, most airbags failures cluster between 13,000 and 70,000 miles, with the median around 40,000. A quarter of owners report trouble before 13,000; a quarter make it past 70,000. 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.
