A recall was issued for a faulty passenger side airbag sensor on the Infinity G37 model year 2007 -2008 (08V521000). I own a 2009 G37 and it would appear this car is experiencing the same safety issue. The airbag off light for the front passenger seat remains illuminated even with a 200 pound adult seated in it.

A recall was issued for a faulty passenger side airbag sensor on the Infinity G37 model year 2007 -2008 (08V521000). I own a 2009 G37 and it would appear this car is experiencing the same safety issue. The airbag off light for the front passenger seat remains illuminated even with a 200 pound adult seated in it. I also have a constantly flashing airbag warning that is displayed on the dashboard. I am extremely concerned that should my vehicle be involved in a crash, passenger side airbag will not deploy even though there is someone seated in that seat. Infiniti has stated that to repair this issue will cost over $5000 which is nearly the entire value of the car. This recall should be extended to additional model years of the G37.

Car got a flashing airbag light after battery replacement. Reset multiple times just for light to come back. Took to Mears Nissan dealership for diagnosis. Diagnosed with bad occupant detection sensor. Dealership quoted me $4,500 for part without labor. Perfectly good car no longer has operating airbags, my personal safety is now at risk because the cost of repair is greater than the cars value, and the part is on back order for an extended unknown period of time. Vehicle is available for inspection. No other lights at time of incident.
