What stands out
No new NHTSA airbags complaint has been filed on this vehicle in over 5 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.

The failure pattern owners describe
Owners report two opposite and equally serious problems: airbags deploying without any collision, and airbags failing to deploy during crashes.
Random deployment incidents occurred as early as one month of ownership at highway speeds with no impact, causing eardrum rupture and severe bruising. Nissan Consumer Affairs accused one owner of fraud and refused assistance, telling the owner that airbags "deploy sometimes without any collision" and that this is normal behavior.
In separate incidents, front airbags failed to deploy during rear-end collisions at 40 MPH, side-impact crashes at 25 MPH, frontal impacts at 60 MPH, and a totaled vehicle accident. Owners sustained facial bruises, hand sprains, and multiple pain injuries from undeployed airbags. One vehicle had only the driver airbag deploy while the passenger side remained inactive during a multi-occupant accident. No warning lights appeared before these crashes, and dealers provided no repair or diagnosis.
Additional safety system malfunctions include the Automatic Emergency Braking system activating at 80 MPH without obstacles, causing a guard-rail crash; front bumper sensors triggering hard braking on phantom objects; and occupancy sensors disabling the passenger airbag when the seat is empty while falsely warning of occupancy. One owner's warning light concern was dismissed by a rental company before a subsequent crash.

Failure modes owners describe
Curtain airbags deploy without collision
Curtain/side airbags deployed spontaneously while vehicle was traveling at highway speeds with no accident, collision, or impact. Occupants sustained injury from deployment.
When: Less than 1 month of ownership; ~24 miles on vehicle; also reported at 52,000-60,000 miles
Symptoms owners cite: Airbags deploy while driving at 55 MPH with no collision; Airbag cover swung off exposing airbags with no impact; Side airbags deployed during normal driving
Repairs/costs cited: Dealership inspected; consumer inspector confirmed vehicle was not wrecked and malfunction was not owner's fault. Vehicle left unrepaired for 1.5 months with obstructed view and locked seatbelts.
Recalls/TSBs owners mention: Nissan Consumer Affairs refused assistance, accused owner of fraud, claimed airbags deploy 'sometimes without any collision' and are 'supposed to' behave this way. Refused rental car assistance after 5 days.
Front airbags fail to deploy in collision
Front airbags did not deploy during crashes at various speeds and impact severities, leaving occupants unprotected. Multiple incidents reported with no warning lights illuminated prior to collision.
When: At 25 MPH turning; at 60 MPH after sliding on ice into pole; at freeway speeds; at 52,000-53,000 miles; totaled vehicle accident
Symptoms owners cite: No airbag deployment during rear-end collision at 40 MPH; No airbag deployment during side-impact at 25 MPH; No airbag deployment during frontal impact at 60 MPH after ice slide; No airbag deployment in totaled vehicle accident; Only driver-side airbag deployed in multi-occupant accident, passenger side did not deploy
Repairs/costs cited: Vehicles towed; not diagnosed or repaired. One owner sustained facial bruises and impacts requiring medical treatment (hand sprain, head pain, shoulder pain, neck pain, foot pain, ankle pain); another sustained injuries from hitting steering wheel.
Recalls/TSBs owners mention: Manufacturer told owner vehicle was not in a recall. Dealer notified but provided no assistance. No repairs performed.
Automatic Emergency Braking (AEB) system activates without cause
AEB system engaged automatically at highway speed with no obstacle present, causing hard braking and vehicle spin-out. Traction control and ABS locked up tires, resulting in crash into guard rail.
When: At 80 MPH on interstate late at night
Symptoms owners cite: AEB system activated spontaneously at 80 MPH; Loud grinding sound when braking; Traction control engaged and ABS locked up tires; Vehicle spun out and crashed into guard rail
Recalls/TSBs owners mention: Local Nissan dealership acknowledged awareness of AEB malfunction but did not offer repair or assistance.
Front bumper sensor malfunction triggering false braking
Front bumper sensor detects objects that are not present on the road, causing automatic hard braking with grinding noise.
Symptoms owners cite: Sensor detecting things in road that aren't there; Automatic hard braking without cause; Loud grinding sound during false brake application
Occupancy sensor misdetects passenger presence
Occupancy sensor indicates someone is sitting in passenger seat when seat is empty, triggering seatbelt warning light and disabling passenger airbag.
Symptoms owners cite: Passenger seat occupancy sensor detects presence when seat is empty; Buckle seatbelt light activates for empty passenger seat; Passenger side airbag disabled incorrectly
Airbag warning light malfunction with no airbag deployment
Warning light illuminated (front lights warning or airbag light) but airbags failed to deploy during collision. System displayed 'REFER TO OWNER'S MANUAL' message instead of deploying.
When: At accident involving totaled vehicle; freeway accident
Symptoms owners cite: Airbag warning light present but airbags do not deploy; System displays 'REFER TO OWNER'S MANUAL' instead of deploying airbags; Warning light for front lights appeared but dealership dismissed concern
Repairs/costs cited: One vehicle was totaled; driver sustained minor scratches and bruises only due to seatbelt use.

At what mileage does the airbags typically fail?
Across the 9 complaints that reported odometer mileage, most airbags failures cluster between 5,600 and 52,000 miles, with the median around 30,000. A quarter of owners report trouble before 5,600; a quarter make it past 52,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
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.
Are there any recalls related to airbags?
No active recalls currently cover airbags issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
