Owners of 2016 Nissan Sentras report two major categories of airbag problems: deployment failures and sensor/indicator malfunctions.
Deployment failures dominate these complaints. Multiple owners describe collisions where airbags simply did not deploy—rear-end impacts at 60 mph, head-on crashes at 45 mph, high-speed truck collisions at 55+ mph, multi-vehicle impacts, and side-impact T-bones. One owner hit by a big rig reports the entire airbag system failed after a previous recall repair. In one case with metal fragmentation during deployment, the driver-side airbag burst open with metal shards and black smoke, injuring the occupant's rib cage.
Occupant-detection sensor issues appear repeatedly. The passenger airbag warning light illuminates inconsistently—sometimes when a passenger is seated, other times not—even for the same passenger of normal weight on the same seat. Nissan has acknowledged these sensor malfunctions but reported inability to fix them due to their intermittent nature. One owner received a Takata recall notice (17V-253000, June 2017) but dealers could not obtain repair parts for weeks, with parts-availability coordination failures between manufacturer and dealerships.
Spontaneous deployments also occur: one driver experienced airbag deployment when a door was slammed while parked, and steering-wheel and dash airbags deployed at 35 mph on a rural road.
Post-recall, some owners still experienced failures. One owner had airbags serviced during an oil-change recall appointment, only to have them fail to deploy in a subsequent high-speed accident.
Failure modes owners describe
Airbag metal fragmentation and explosive deployment
Driver-side airbag deployed with metal fragments ejecting from the airbag module during a front-side impact collision, accompanied by thick black smoke. Contact sustained rib cage injuries.
When: 6,000 miles
Symptoms owners cite: Metal fragments expelled from airbag; Thick black smoke during deployment; Airbag exploded in contact's face
Repairs/costs cited: Vehicle deemed destroyed; manufacturer made aware
Passenger airbag sensor malfunction — inconsistent occupant detection
Front passenger occupant-detection sensor malfunctions intermittently. Same passenger (110–115 lbs) in same seat yields inconsistent readings while vehicle is in motion: sometimes system indicates airbag will deploy in accident, other times indicates it will not. Nissan acknowledged the problem but has been unable to correct it due to its inconsistent nature.
Symptoms owners cite: Occupant-detection sensor malfunctions inconsistently; Airbag deployment status changes unpredictably for same passenger and seat
Repairs/costs cited: Owner requested sensor replacement; Nissan acknowledged but unable to fix due to intermittency
Recalls/TSBs owners mention: Nissan acknowledged the passenger sensor malfunction
Takata airbag recall parts unavailability
Owner received recall notification (NHTSA Campaign 17V253000, June 2017) for Takata airbags but dealer stated parts were unavailable. Manufacturer stated parts were available and redirected to dealer, creating a parts-distribution disconnect. Owner had not experienced an actual airbag failure.
When: Recall issued June 2017
Symptoms owners cite: Recall notice issued; parts unavailable at dealership
Repairs/costs cited: Parts unavailable at dealer; unclear if repair was completed
Recalls/TSBs owners mention: NHTSA Campaign 17V253000 (Takata airbags); manufacturer said parts available but dealer could not obtain them
Airbag failure to deploy — front-end collision
Both driver-side and passenger-side airbags failed to deploy during a rear-end collision at 60 mph. Vehicle struck the vehicle in front after sudden stop. No injuries reported; vehicle not repaired or inspected by manufacturer.
When: 5,000 miles
Symptoms owners cite: Driver-side airbag did not deploy; Passenger-side airbag did not deploy; Rear-end collision at 60 mph
Repairs/costs cited: Vehicle towed to unknown location; not repaired
Airbag failure to deploy — head-on collision
Airbags did not deploy during head-on collision at 45 mph. Contact lost consciousness and sustained head injuries requiring medical attention. Vehicle deemed total loss by insurance company.
When: Mileage not available
Symptoms owners cite: Airbags did not deploy; Head-on crash at 45 mph
Repairs/costs cited: Vehicle deemed total loss
Airbag failure to deploy — severe front-end impact
Airbags failed to deploy during severe front-end collision that totaled the vehicle. Both occupants sustained injuries. Vehicle was standing still in drive when struck.
When: 12/07/2017
Symptoms owners cite: Airbags did not deploy during severe front-end impact; Vehicle totaled
Repairs/costs cited: Vehicle totaled; $27,000+ loss
Airbag failure to deploy — intersection collision
Airbags failed to deploy when another vehicle crashed into the front end at an intersection. No injuries reported; collision speed unknown.
When: Unknown mileage
Symptoms owners cite: Airbags did not deploy during front-end collision
Repairs/costs cited: Vehicle towed; unknown if destroyed
Passenger airbag warning indicator — intermittent illumination after recall repair
Front passenger warning indicator illuminated intermittently when front seat occupied by adult. Vehicle had been previously repaired per NHTSA Campaign 16V244000 (airbags), but the remedies failed. Illumination persisted after the recall repair.
When: 55,000 miles
Symptoms owners cite: Front passenger warning indicator illuminates intermittently; Indicator lights even with adult occupant in seat
Repairs/costs cited: Previous recall repair (16V244000) did not resolve the issue
Recalls/TSBs owners mention: NHTSA Campaign 16V244000 (airbags); repair failed to correct problem
Airbag failure to deploy after prior recall repair
Airbags failed to deploy during high-speed collision (55+ mph) with a large truck that totaled the vehicle. Owner had previously taken the vehicle for an oil change and was told airbags were recalled and fixed at that service. Despite recall repair, airbags did not deploy in the accident.
When: Post-recall repair
Symptoms owners cite: Airbags did not deploy at 55+ mph collision; Prior recall repair did not prevent failure
Repairs/costs cited: Airbags previously 'fixed' per recall at dealership during oil change; failure occurred after repair
Recalls/TSBs owners mention: Recall repair completed but airbags did not deploy in subsequent accident
Takata recall parts delay — misleading timeline
Nissan issued recall 17V-253 (dated April 13, 2017) for Takata airbags but did not release parts for repair for several weeks after recall announcement. Owner alleges manufacturer is misleading the public by posting recall without an available remedy.
When: April 13, 2017 recall date
Symptoms owners cite: Recall issued without available parts; Delay of several weeks before parts became available
Repairs/costs cited: No parts available at time of recall announcement
Recalls/TSBs owners mention: NHTSA Campaign 17V-253 (Takata airbags, April 13, 2017) issued without available repair parts
Passenger airbag warning indicator — illumination at low speed
Passenger-side airbag warning indicator illuminated while driving at 35 mph. Vehicle was not diagnosed or repaired; manufacturer was made aware.
When: 3,500 miles
Symptoms owners cite: Passenger airbag warning indicator illuminated; Illumination during normal driving
Repairs/costs cited: Vehicle not diagnosed or repaired
Passenger airbag off-light malfunction — incorrect occupant sensing
Passenger airbag off-light comes on intermittently when passenger of normal weight is seated, indicating the airbag would not deploy. Light should remain off when a passenger of appropriate weight is present.
Symptoms owners cite: Airbag off-light illuminates with passenger in seat; Inconsistent occupant-weight sensing
Airbag failure to deploy — multi-vehicle accident
Airbags did not deploy during a multi-vehicle accident resulting in total loss. Seat frame broke during impact and vehicle frame bent. Owner had received maintenance at Nissan dealer on June 5 but was not notified of any open recalls.
When: June 5 (maintenance date)
Symptoms owners cite: Airbags did not deploy; Seat frame broke during impact; Vehicle frame bent
Repairs/costs cited: Total loss; seat and frame damaged
Recalls/TSBs owners mention: No recall notification provided despite dealer maintenance visit
Airbag failure to deploy — chest impact without seatbelt lock
Airbags failed to deploy in a car accident. Seatbelt did not lock in place and did not support upper body, resulting in contact's chest hitting the steering wheel. Seatbelt warning light illuminated on dash after accident.
When: Unknown mileage
Symptoms owners cite: Airbags did not deploy; Seatbelt failed to lock; Chest struck steering wheel
Repairs/costs cited: Seatbelt light on dash post-accident
Spontaneous airbag deployment — stationary and low-speed conditions
