What stands out
Airbags accounts for 49% of every owner complaint on file for this vehicle — the dominant problem area across 5 categories tracked.
Owners have filed 49 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.
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 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. Infiniti 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.
full bulletin at NHTSA ↗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.

When replacing a BCM, make sure to - Follow information in the appropriate Service Manual - Use CONSULT-III plus to perform configuration - Select the correct vehicle in CONSULT-III plus - Confirm the VIN is correct (matches the vehicle) in CONSULT-III plus - Select/install the correct configuration

The failure pattern owners describe
Owners report the front passenger occupant sensor consistently fails without warning or accident, triggering an airbag warning light that stays on permanently. The sensor fails to detect occupants or signal the airbag control unit, rendering the passenger airbag and often the entire supplemental restraint system non-functional. Owners describe the light illuminating at mileage ranging from 23,500 to 100,000 miles and remaining lit regardless of whether anyone sits in the passenger seat.
Dealer diagnostics point to the occupant sensor unit (OCS) with error code B1018. The only factory repair is full passenger seat replacement because the sensor is integrated into the seat assembly and cannot be serviced separately. Quotes from Infiniti dealers range from $4,200 to $15,000, with most clustered between $6,000 and $8,000 for parts alone, plus labor. Infiniti USA declines financial assistance once the vehicle is outside factory warranty, leaving owners liable for the entire cost. One complaint references an earlier 2008 Infiniti recall (08V521000) for a similar OCS varistor defect, raising the question why the 2011 G37 was not included. Online forums and owner communities confirm this is not isolated—owners report seeing the same failure across many G37s and other Nissan/Infiniti models, yet no recall has been issued for the 2011 G37 despite the safety criticality.

Failure modes owners describe
Occupant Classification System (OCS) Sensor Failure
The occupant sensor in the front passenger seat fails to detect occupants or properly communicate with the airbag control unit, causing the passenger airbag warning light to illuminate and remain on. This prevents passenger airbag deployment in a crash, even when an adult is seated.
When: Between 23,500 and 100,000 miles; failures reported as spontaneous with no accident or impact trigger
Symptoms owners cite: Passenger airbag warning light illuminated or flashing on dashboard; Airbag warning light remains on regardless of whether passenger is seated; Dashboard display shows 'passenger airbag off' even with occupant in seat; Light will not extinguish and returns immediately after being cleared; In rare cases, warning light present at startup
Codes mentioned: B1018 (OCS unit failure / Occupant Sensor Unit Failure), DTC B1018
Repairs/costs cited: Infiniti dealers quote $4,200–$15,000 to repair, with most quotes in the $6,000–$8,000 range. Repair requires replacement of entire front passenger seat assembly (seat bottom/seat cushion containing the OCS hardware) because the sensor cannot be replaced independently. Labor typically quoted as 1–2 hours but the part cost dominates. Owners report independent mechanics confirm similar pricing ($6,500 for part alone). Extended warranty programs do not cover the failure.
Recalls/TSBs owners mention: Infiniti USA declined financial assistance, citing vehicles are out of factory warranty. One complaint references a prior 2008 Infiniti recall (08V521000) for passenger airbag deployment due to a varistor in the OCS control unit manufactured out of specifications by Continental Automotive Systems; however, the 2011 G37 was apparently not included in that remedy. One owner reports Infiniti USA offered a partial discount, reducing repair cost from ~$10,000 to $7,000, but no full recall has been issued for the 2011 G37.
Total SRS System Shutdown
Occupant sensor failure causes complete suppression of airbags across the vehicle—not only passenger but driver and side airbags as well. With the warning light on, dealers advise that none of the airbags will deploy in a crash.
When: Varies; one report at 62,251 miles; failures sporadic across model year
Symptoms owners cite: Airbag warning light illuminated or flashing; All airbags rendered non-functional or suppressed; Dashboard indicates airbag system is compromised; Dealer confirms entire SRS cannot be certified as functional until sensor is replaced
Codes mentioned: B1018
Repairs/costs cited: Entire passenger seat replacement ($4,200–$15,000). Dealers state all airbags remain inoperable until repair is completed.
Recalls/TSBs owners mention: No recall issued. Manufacturer offers no financial assistance outside warranty period.
Intermittent Airbag Off Warning with Passenger Present
Passenger occupancy sensor intermittently reports airbag as off even when an adult occupant is correctly seated, creating unpredictable failure that owners cannot verify between trips.
When: Sporadic; can occur repeatedly or intermittently throughout driving
Symptoms owners cite: Passenger airbag light flashes on and off during driving with passenger in seat; Warning light shows airbag is off even when seat is occupied; Light appears random and inconsistent; Affects passenger detection regardless of occupant weight or position
Codes mentioned: B1018
Repairs/costs cited: Passenger seat replacement ($6,000–$8,000 range). Owners report clearing the code does not resolve the underlying sensor issue.
Recalls/TSBs owners mention: No warranty coverage. No recall. Manufacturer declined involvement in cases reviewed.

My passenger seat belt light started blinking and the dealer said I needed a new chip in the seat at a cost of $8,000.
