This just in from CNN:
The German automaker says the recall involves the 2006 3 Series, the 2004-2006 5 Series, and the 2004-2006 X3 compact sport utility vehicle.
The National Highway Traffic Safety Administration said in a posting on its Web site Wednesday that small cracks could develop in a seat detection mat and lead to the front passenger air bags to be deactivated.
It would also turn on the passenger air bag “on-off ” light. NHTSA says the head protection system would not be affected.
