I believe there is a serious safety issue related to the placement of the air bag sensor. My wife and a CO-workers wife were involved in an accident that severely deformed the front of a 2012 Toyota Corolla without triggering the airbag sensor. upon inspection, it appears that the portion of the car that the airbag sensor is attached to, moved over a foot and a half without triggering the air bag sensor. As a former ase master technician and technical expert for the better business bureau, this may be a serious design flaw that could endanger the health and safety of other 2012 Corolla owners. I file a complaint with Toyota USA and I am waiting for their response.
