I purchased this vehicle, 2012 Infiniti G 37XS in September 2023.

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. …
