The defect

BMW of North America, LLC. (BMW) is recalling certain model year 2015 BMW X3 sDrive28i, X3 xDrive28i, X3 xDrive35i, X3 xDrive28d, X4 xDrive28i and X4 xDrive35i vehicles, and model year 2014-2015 X5 xDrive35i, X5 sDrive35i, X5 xDrive50i, and 2014 X5 xDrive35d vehicles. The affected vehicles have a driver's frontal air bag inflator that may have been improperly welded.
