 BMW is recalling more than 390,000 vehicles because they may have been equipped with a malfunctioning airbag that could explode upon impact. Faulty front airbags were produced by Takata, which last decade was subject to one of the country's largest recalls ever due to its defective airbags. The recall covers certain 3 Series sedans and 3 Series sport wagons from 2006 through 2012.
