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.

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 ↗Nissan is conducting a Voluntary Service Campaign on Model Year 2007-2012 Nissan Altima (L32) Sedan and Coupe vehicles to inspect the brake systems in vehicles with an illuminated brake warning lamp. Nissan dealers will inspect the brake system and confirm that no brake fluid leak is present. If no leak is present, the reservoir will be topped off. If a leak in the brake master cylinder is identified, the brake master cylinder will be replaced. The affected vehicles are equipped with a brake warning lamp that will illuminate to alert the driver when fluid in the brake fluid reservoir is low. Fluid in the reservoir may become low due to normal brake pad wear and not because of any brake syste

The failure pattern owners describe
The 2011 Nissan Altima airbag system shows two main failure patterns. The most common is a passenger-side occupancy sensor that falsely indicates the airbag is off when an adult is seated (weights 102–240 lbs reported), or illuminates unpredictably during normal driving. Dealers cannot reproduce the fault during service and often claim the system is "operating as designed." Nissan has issued recalls for the exact same sensor defect on 2007–2008 and 2013–2016 Altimas, but excludes 2011 models. Repairs quoted at $550 for seat replacement, plus labor, with dealers initially denying warranty coverage.
The second failure pattern is airbag non-deployment during front-impact collisions. Owners report sustained injuries (chest, neck, back) where airbags should have cushioned impact. A few complaints document SRS warning lights that persist despite 12+ repair attempts and complete wiring harness replacement. One owner noted side curtain and side-impact bags deployed during a T-bone when the passenger seat was empty, adding hundreds to collision repair costs.
Across all reports, dealers struggle to diagnose root causes, perform guesswork parts replacement, and leave vehicles unrepaired.

Failure modes owners describe
Passenger seat occupancy sensor malfunction
Passenger-side airbag off indicator illuminates when an adult is seated, or fails to illuminate when seat is occupied, indicating the sensor does not properly detect occupancy. This intermittent fault prevents airbag deployment in a collision when passenger is present.
When: Typically appears early in ownership (1-3 years) or after low-speed impact; some reports ongoing for life of vehicle
Symptoms owners cite: Passenger airbag 'off' light illuminated while occupied seat has adult passenger; Passenger airbag light flashing intermittently while driving; Light remains off regardless of passenger weight (102-240 lbs reported); Condition is intermittent and cannot be replicated at dealer; Airbag light on with passenger, off with empty seat
Repairs/costs cited: Dealer quoted $550 for passenger seat replacement plus labor. Many dealers report they cannot find codes and declare system 'operating as designed.' Multiple owners report repair attempts with no resolution; some dealers performed resets with temporary or no results.
Recalls/TSBs owners mention: Nissan has issued recalls for 2007-2008 Altima (08V521000) and 2013-2016 Altima for the same sensor issue, but 2011 models are not included despite matching failure pattern. Nissan corporate position is that repairs are owner responsibility, not warranty coverage.
Airbag non-deployment in front-impact collisions
Driver and passenger airbags fail to deploy during front-end and frontal collision impacts with sufficient force. Owners sustain injuries (chest, neck, back) that would typically be mitigated by airbag cushioning.
When: At time of collision; no mileage pattern identified
Symptoms owners cite: Airbags did not deploy in bumper-to-bumper front-end collision; Airbags did not deploy in serious front impact (vehicle totaled, rear quarter panel crumpled); Driver chest struck steering wheel despite seatbelt; airbag should have deployed
SRS warning light illumination with no diagnosis
SRS airbag warning light turns on and stays on after minor low-speed collision or intermittently during normal operation. Dealers perform extensive parts replacement (modules, sensors, wiring) without identifying root cause.
When: After 0-5 mph parking lot collision (complaint #1); intermittently during normal driving (other complaints); at various mileages (31,000 to 170,000 miles)
Symptoms owners cite: SRS airbag warning light comes on and does not go off; Airbag warning light flashing continuously; Warning light illuminates during startup
Repairs/costs cited: Technicians replaced SRS module, sensors, and entire SRS wiring harness (on back order with no ETA). Despite 12+ repair attempts over 6 months, no diagnosis established. One complaint involved partial dashboard removal without resolution.
Side curtain and side-impact airbag unexpected deployment
Side curtain and seat-mounted side airbags deployed during a T-bone collision even though no passenger occupied the passenger seat, incurring additional repair costs.
When: T-bone collision on passenger side
Symptoms owners cite: Side curtain airbag deployed when passenger seat was unoccupied; Seat-mounted side airbag deployed when passenger seat was unoccupied
Repairs/costs cited: Repair costs added hundreds of dollars to collision repair.
Undiagnosed airbag system faults
Airbag warning light or sensor faults that dealers cannot diagnose or replicate, leaving failures unrepaired despite multiple service visits and multiple diagnostic attempts.
When: Various mileages and timeframes; some ongoing since vehicle purchase
Symptoms owners cite: Airbag warning light illumination; Airbag sensor malfunction indicated by diagnostic scan; Traction control indicator illumination (concurrent with airbag issues in one case)
Repairs/costs cited: Mechanic's diagnostic scanner found malfunction but reset was temporary or ineffective. Dealers unable to replicate issues and stated 'nothing is wrong' or 'we don't see anything.' Multiple service visits yielded no repairs.
