2012 Infiniti G-Class air bags problems

“I purchased this vehicle, 2012 Infiniti G 37XS in September 2023. The vehicle was basically brand new with less than 2200 miles on it and I have driven it very little up to that point, October 2024, as it is not my primary vehicle. Around [XXX], I believe it was around 8100 miles and change on the vehicle, a warning light came on my dash regarding my passenger airbag. Since that date, I have worked with Plaza Infiniti in Creve Coeur, who has looked at the vehicle a few times and identified that there is no part replacement other than OEM that can fix this issue. However, the part has been discontinued. Today, I reached out to Infiniti directly, and with a sad heart, they refuse to even listen to me. Now, I have a vehicle that has a safety issue and no way to fix it. The part number 87300–1NL6A, is the lower seat assembly for the passenger side of my 2012 Infiniti G 37XS. This part also has the occupant sensor which is directly affecting the airbag. The sensor is not replaceable separately of the lower seat assembly.”

“This is a follow up to a compliant that I put in early this year or late last year. There is not much discussion of the failed occupancy sensor for the passenger front airbag on this website, but it does get discussed online more often. I am not sure why Infiniti says the entire seat must be replaced ($5,000 or so) rather than just replacing the sensor. Also, the seat has now been discontinued. It's unfortunate that there is no other solution that I am aware of other than finding a discontinued seat.”

“2012 Infiniti G25x: Occupancy sensor failed (diagnostic code B1018) around 132,000 miles. This is a common problem with Infiniti cars. Apparently for 2007 and 2008, there were recalls, but this problem continued into later years with no recall. The cost I was quoted to repair this (replacing the entire passenger seat) was $5,000, which is not practical for a 12 year old car. Although I haven't been able to get an exact answer, it seems that this failure not only shuts off the front passenger airbag, but the entire SRS system (all airbags and all pretensioners) - I haven't been able to get a definite answer from multiple dealers that I contacted or from the Infiniti national customer service. Otherwise, the car has been the most reliable car I ever owned, but there should be at least some compensation for this problem which has existed for a number of years.”

“The contact owns a 2012 Infiniti G37. The contact stated that the air bag warning light was illuminated, and the message "Seat Belt Off" was displayed. The vehicle was taken to the dealer, where DTC code: B1018 was retrieved. The dealer determined that the passenger's side seat occupant classification system sensor and module diagnostic unit had failed and needed to be replaced. The vehicle was not repaired due to the cost. The dealer referred the contact to the NHTSA Hotline for assistance. The manufacturer was not notified of the failure. The failure mileage was approximately 178,789.”

“I’ve owned this 2012 g37 for a few years and had no issues whatsoever. However within the last couple of months, my air bag light came on and has been flashing since. I’ve taken it to get inspected and had the system checked and was told my passenger seat occupant sensor malfunctioned and is throwing the code on. The sensor itself, very easily replaced, is unable to be bought by itself. Repairs by the dealership is well over 5,000 for the seat and labor. The sensor is being sold as a component part of the bottom build of the seat, and cannot be sold otherwise. The issue with the sensor not being active, prevents the activation of the passenger airbag regardless of the seat being occupied or not. My concerns are that I won’t be able to safely commute with passengers on the road and also being able to pass state inspection, as needed per law per state. Without this sensor, driving is an everyday peril, a safety concern a driver has no control over with other vehicles on the road. There has not been any prior incidents that have occurred that could cause this electronic issue.”

“Passenger Side Air Bag sensor flashes possibility due to faulty sensor in passenger seat. Water enters cabin on passenger side causing water to pool on floorboards, possibly causing electrical damage and failure. Water entering could be due to flawed design in water channel or sunroof.”
