RepairPal Expert Overview:

With the front passenger seat occupied and in the full forward position, the seat position sensor will cause a 30 millisecond deployment delay between the first and second stages of the dual-stage frontal passenger airbag. In the event of a crash, this delay may result in increased head injury to certain front seat occupants. Dealers will reprogram the airbag control module software to correct this concern.

Pontiac G8 Reviews

I have a 2008 G8 GT and it has been absolutely a perfect car!! The nearly 400 horsepower is such a pleasure to have available, and the chassis/suspension is SOOO silky-smoothe... like NO OTHER CAR I've ever driven in my life!! I've driven Lexuses, BMW's, Mercedes and more..... but I have NEVER driven another car that has the same feelings of stability, control, not to mention the 400 horsepower!! It's off the scale!!
