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.

Owners have filed 47 airbags complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 15 model years of Nissan Sentra in our records for airbags problems, this one ranks #3 by owner-complaint volume.
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 of the 2008 Nissan Sentra report three primary airbag system categories of failure:
Warning Light Persistence. The airbag warning light comes on and blinks continuously or intermittently, appearing without any collision. Dealers reset the code, but it recurs within days or weeks—sometimes within hours. Mileage ranges from 56,000 to 150,000 miles. Owners say dealers cannot reliably identify the underlying cause; diagnostic codes (B1134, B1018, B1049, B1134) are thrown, but repair recommendations vary widely: clock spring replacement, module replacement, full seat replacement ($3,000 new, $700+ used). Multiple owners report that replacing the seat twice or replacing a $675 computer chip has not eliminated the light.
Non-Deployment During Crashes. Airbags have failed to deploy during frontal and multi-vehicle collisions at speeds of 20–50 mph, resulting in occupant injuries ranging from bruising to internal injuries, broken ribs, and cervical fractures. In one head-on embankment impact, airbags deployed only 30 seconds after impact, and the seat belt tightened so violently it broke and caused internal bruising.
Spontaneous Deployment. Four front-passenger airbags have deployed while the vehicle was parked and unoccupied, and during low-speed maneuvers like closing a door or shifting from drive to park—with no collision or damage. Concurrent seat belt failures have also been reported, including latch failures that allowed a child safety seat to flip.
Nissan has issued one voluntary service campaign (PM952) for seat positioning but no recall for non-deployment or sensor faults. Dealers state the airbag malfunction is "common" but offer no manufacturer support.

Failure modes owners describe
Airbag Warning Light Illumination / Blinking
Dashboard airbag light comes on and blinks continuously or intermittently without any accident or collision. Light often reappears after dealer reset. Owners report the light appearing randomly while driving or at startup, sometimes lasting only hours or days before coming back on.
When: Typically 60,000–130,000 miles; some as early as 56,000 miles
Symptoms owners cite: Airbag warning light blinking or illuminated on dashboard; Light persists or recurs after dealer reset; Light comes back on within days or weeks of reset; Appears without collision or impact
Codes mentioned: B1134, B1018, B1049, 81134
Repairs/costs cited: Dealers cite faulty airbag modules, clock springs, driver airbag assembly, passenger seat occupancy sensors, or full seat replacement. Costs range $975 to $3,400 for parts and labor. Owners report dealerships unable to diagnose root cause with certainty.
Recalls/TSBs owners mention: Voluntary service campaign PM952 for side curtain airbag positioning issued in May 2009. No manufacturer-issued recalls for non-deployment warning light issues on 2008 Sentra identified in narratives. Dealers have told owners the issue is 'common' but no TSB or recall issued.
Airbag Non-Deployment in Collision
Airbags fail to deploy during crashes despite impact forces that should trigger deployment. Includes head-on collisions, rear-end collisions, and embankment impacts. Vehicles were destroyed or severely damaged but occupants were unprotected by airbags.
When: 16,000 to 150,000 miles; occurs during actual accidents
Symptoms owners cite: No airbag deployment during frontal impact; Vehicle destroyed or severely damaged; Occupant injuries (bruising, broken ribs, fractures, cervical injuries, internal bruising); Airbag light may illuminate after impact
Repairs/costs cited: No repairs documented in narratives; vehicle damage too severe for restoration in most cases. One case noted seat belt failure concurrent with airbag non-deployment.
Unexpected Airbag Deployment (Non-Collision)
Airbags deploy spontaneously without collision, impact, or vehicle damage. Occurs while vehicle parked, stationary, or during low-speed maneuvers (closing door, shifting from drive to park, slow curb strike). Four airbags have deployed in some incidents while vehicle unoccupied and parked.
When: 65,000 to 107,537 miles
Symptoms owners cite: Passenger side curtain and door airbags deploy while parked; Four airbags deploy on front passenger side without impact; Deployment occurs when closing passenger door; Deployment during gear shift (drive to park) at low speed; No vehicle damage or collision; May occur with occupant in vehicle or unoccupied
Repairs/costs cited: One case repaired under voluntary recall PM952 in May 2009; others not repaired or diagnosis inconclusive.
Recalls/TSBs owners mention: Voluntary service campaign PM952 issued (addresses side curtain airbag positioning during assembly). Manufacturer notified in some cases; conducted investigation in at least one case.
Seat Belt Failure / Pretensioner Malfunction
Seat belts fail or malfunction in conjunction with airbag issues. Belts do not retract after airbag deployment, tighten excessively, fail to lock child safety seats, or break. Right front seat belt pretensioner failure reported; seat belt latch failure in one case caused child car seat to flip.
When: 82,000 miles reported for latch failure; concurrent with airbag light issues
Symptoms owners cite: Seat belt does not lock properly; Seat belt tightens excessively and does not stop; Child safety seat insecure due to belt latch failure; Child seat flips; child ejected but uninjured; Seat belt breaks under tension
Repairs/costs cited: Right front seat belt assembly replaced under warranty (one case). Other cases not repaired or diagnosis unconfirmed.
Airbag Sensor Malfunction (Seat Occupancy / Position)
Passenger seat occupancy sensors or position sensors malfunction, triggering airbag warning lights and disabling airbags. Sensor failures prevent airbags from arming. Dealer diagnosis often inconclusive; some cite bent or misaligned seats as cause.
When: Varies; some as early as mid-life of ownership
Symptoms owners cite: Airbag warning light illuminates; Passenger-side airbag disabled or will not deploy; Dealer indicates sensor fault on diagnostic; Dealer unable to confirm sensor replacement will fix issue
Codes mentioned: B1018, B1134
Repairs/costs cited: Dealers recommend seat replacement ($3,000+ new, $700+ used plus labor) or computer chip replacement ($675) with no certainty of success. Multiple seat replacements have failed to resolve issue.
Recalls/TSBs owners mention: Airbag recall campaigns exist for other Nissan models regarding seat occupancy sensors, but do not include 2008 Sentra. No TSB identified in narratives.
Clock Spring Failure
Airbag clock spring (electrical connector in steering wheel) fails, illuminating airbag warning light. Horn and steering wheel controls may stop functioning concurrently.
When: Varies; no specific mileage pattern provided
Symptoms owners cite: Airbag warning light illuminates; Horn does not function; Steering wheel cruise control / radio controls stop working
Codes mentioned: B1049
Repairs/costs cited: Clock spring replacement cost approximately $1,468 (one case cited combined clock spring and driver airbag assembly replacement). Dealers cite this as unusual failure.
Airbag Module / Circuit Board Failure
Airbag control module or driver module circuit board fails, causing warning light and disabling system. Dealer diagnosis indicates faulty module; replacement cost is high.
When: 129,000+ miles; sporadically illuminating
Symptoms owners cite: Airbag warning light illuminates sporadically or continuously; Light persists after reset
Repairs/costs cited: Module replacement cost not specified in narratives; one case cited $3,000 full airbag module replacement. Part availability delayed significantly (one case ordered in Oct 2015, not received by May 2016).
