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…

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.
The failure pattern owners describe
Buyer takeaway: The 2012 Sentra shows a troubling pattern of airbag malfunctions—some deploy unexpectedly from door slams or headlight adjustment while stationary, while others fail entirely during serious collisions, with documented driver injuries. Persistent airbag warning lights also appear in several complaints, suggesting sensor or electrical issues that deserve professional diagnostic attention before purchase.
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.

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 unexpectedly while driving at normal speed
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.
Airbags deployed when passenger slammed door while stationary
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

On august 25, 2014 while I did escape with my life and my whole body intact, after a witness was on scene she said she her a loud pop, well that loud pop was my front left (immediate driver's side tire) and I ended up in a brick wall. 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
