 BMW is recalling nearly 400,000 vehicles in the U.S. that are equipped with airbag inflators that can explode. Federal regulators say the original steering wheel on 3 Series sedans and sport wagons made between 2006 and 2012 are affected. They may have been replaced with a wheel equipped with a faulty Takata inflator. If that explodes, it could create sharp metal projectiles, possibly resulting in injury or death.
