If you have a Chevy Cobalt built between 2005 and 2006 that doesn't have the optional roof-mounted side impact airbags, you could be getting a recall notice in the mail soon. Apparently Chevy (and presumably the NHTSA) discovered that there isn't sufficient padding to meet federal requirements in these vehicles, and unacceptable head injuries could result in a collision. Scary to think there's an acceptable amount of injury that would be tolerated, but anyway. As a fix, dealers will add "energy absorbing plastic" to the headliner trim to help soften the blow should your head strike the headliner in a crash. The recall affects 98,000 Cobalts on the road.
