One problem related to air bag on-off switch has been reported for the 2011 Infiniti G37. The most recently reported issues are listed below.
The air bag sensor light on the dash has illuminated. This means that the switch in the seat does not detect an occupant so the air bag will no deploy in a crash. Infinit of memphis wants to charge $8000 to replace the seat! this is a safety hazard and should be a recall issue. I see many complaints on this website about the exact same issue. How do we initiate a manufacturer recall?.
