SERVICE INFORMATION Changes or modifications to the front seat assembly trim materials may affect the proper operation of the Front Seat-Mounted Side-Impact Supplemental Air Bags and Passenger Occupant Classification Sensor and could result in serious personal injury or death. Nissan STRONGLY RECOMMENDS AGAINST making any change to seat trim materials from the factory equipped condition. This specifically applies to replacing the seat trim with non-factory materials; adding leather/cloth seat covers, seat pads, or seat storage pouches, etc. around or over the seat back and the passenger seat cushion. See this bulletin for further detail.

What stands out
No new NHTSA airbags complaint has been filed on this vehicle in over 7 years — the issue may be aging out of the active population.
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.
SERVICE INFORMATION Information necessary to service the Supplemental Restraint System (SRS) safely is included in the "RESTRAINTS" section of the Electronic Service Manual (ESM) for each vehicle. IMPORTANT: Turn the ignition switch OFF, disconnect both battery terminals, and wait at least 3 minutes before performing any service on the SRS. See this bulletin for further detail.
full bulletin at NHTSA ↗SERVICE INFORMATION If you confirm there is a need to replace the steering wheel switches on an Applied Vehicle for any reason: - Do not replace the driver air bag module. The steering wheel switches are now available as a separate service part. - Refer to the Service Procedure in this bulletin for steering wheel switch removal and installation instructions. See this bulletin for further detail.
full bulletin at NHTSA ↗SERVICE INFORMATION If you confirm there is a need to replace the driver and/or front passenger seat side air bag module in an Applied Vehicle for any reason: * Do not replace the entire seatback assembly if only the side air bag needs to be replaced. The side air bag module is now available as a separate service part. * Refer to the SE section of the applicable Electronic Service Manual (ESM) for seatback disassembly and assembly instructions.

The failure pattern owners describe
Owners of 2012 Sentras report two opposing failure modes: airbags deploying when they shouldn't, and failing to deploy when they should.
Unexpected deployments occurred when doors were slammed shut on stationary vehicles with keys in the ignition, and when a driver adjusted the headlights while driving. One incident involved curtain and seat airbags both deploying from a door slam. Nissan declined warranty coverage on one case, citing prior trunk repair work as a possible cause.
Non-deployments during actual collisions are more serious. Multiple owners report airbags not firing during 40–55 MPH impacts involving trees, sign posts, and embankments. In one crash at 50 MPH into a tree, an unconscious passenger suffered 4 broken ribs, broken neck, and facial lacerations from the windshield. Another driver hit a culvert after swerving for a deer; the vehicle became airborne and the airbag did not deploy despite $7,000 in damage. One crash at 40 MPH with passenger-side impact also saw no deployment, resulting in bruised ribs and neck pain.
Warning light issues appear separately: owners report airbag lights flashing or remaining on constantly during startup, with no accident history. One vehicle passed inspection despite an active airbag warning light and check engine light.
Owners point to the Passenger Presence Sensor (PPS) module (Special Coverage Adjustment 23520) as a possible cause, though that adjustment did not apply to all VINs reporting issues.

Failure modes owners describe
Curtain and seat airbags deployed while stationary
Curtain and seat airbags deployed when the driver's door was slammed shut while the vehicle was parked with the key in the ignition. No collision occurred. The vehicle had been in a rear accident 3 months prior involving trunk damage.
When: Unspecified mileage; stationary parked condition
Symptoms owners cite: Airbags deployed during door slam while stationary; Vehicle not in motion
Repairs/costs cited: Dealer declined warranty coverage; advised contacting insurance. Prior trunk repair at dealer following rear accident.
Recalls/TSBs owners mention: Dealer stated Nissan corporate office was involved but owner was not contacted and vehicle was not inspected by professional technician
Airbags failed to deploy on passenger side during collision
During a 40 MPH collision when vehicle was struck on the passenger side by another vehicle, forcing the car off road into a wooded area and into a tree, the airbags did not deploy. Driver sustained injuries (bruised ribs, neck, chest, back, abdomen, and knee pain) attributed to lack of airbag deployment.
When: Single collision; mileage unknown
Symptoms owners cite: No airbag deployment during impact; No warning lights illuminated; Driver injuries from collision
Repairs/costs cited: Vehicle towed and deemed total loss by insurance
Passenger airbag failed to deploy during high-speed collision
Passenger airbag did not deploy during a 50 MPH impact when vehicle hit a tree. Owner was unconscious in passenger seat and sustained severe injuries (4 broken ribs, broken neck, multiple facial lacerations from windshield). Owner questions whether defective airbag components noted in 2012 Sentra model year contributed to non-deployment.
When: Approximately 50 MPH collision; unspecified mileage
Symptoms owners cite: Passenger airbag did not deploy; Multiple severe injuries to unconscious passenger
Repairs/costs cited: Passenger side windshield laceration damage documented

Airbags deployed while driver was attempting to turn on the headlights at an undisclosed speed while driving. No collision or accident occurred.
When: 174,000 miles
Symptoms owners cite: Airbags deployed without collision; Deployment triggered while adjusting headlights
Repairs/costs cited: Vehicle not diagnosed or repaired
Recalls/TSBs owners mention: Owner noted Special Coverage Adjustment 23520 for Passenger Presence Sensor (PPS) Module, but VIN not included in that adjustment. Manufacturer made aware of failure.

Roof and passenger seat airbags deployed when a passenger slammed the door shut while vehicle was in drive with foot on brake (not moving). No collision or accident involved.
When: Unspecified mileage; stationary with door slam
Symptoms owners cite: Airbags deployed during door closure; Vehicle stationary; no collision
Repairs/costs cited: No injuries or vehicle damage; no repairs needed
Continuous airbag warning light illumination
Airbag light flashing intermittently at first, then continuously illuminating every time vehicle is started. Owner has never been in an accident.
When: Unspecified mileage; ongoing condition
Symptoms owners cite: Airbag light flashing intermittently; Airbag light on continuously every startup
Airbag light illuminated with blinking pattern
Owner discovered airbag light blinking (initially thought to be seat belt light) along with check engine light on during routine traffic stop inspection. Vehicle passed inspection despite both warning lights being active.
When: Unspecified mileage
Symptoms owners cite: Airbag light blinking; Check engine light also on; Both lights active during inspection
Repairs/costs cited: Vehicle was inspected by police during traffic stop; both warning lights present but vehicle passed inspection

I bought this car with 56,000 now it has 96,000, it has CVT transmission, the step motor is no longer useful; after having run only 40,000 miles is not fair !!!! I know many people who have had the same problem with this type of car, the factory should fix it at no cost to the consumer, I still owe the bank .. $ 7,000 and the repair costs me $ 4,000. You think it's fair to pay so much money, when…

Not pleased with bridgestone, as my vehicle only had no more than 8000 miles on it, but very pleased with the vehicle and it's features. *tr
