Details

What's wrong: Due to a manufacturing process error, the tolerance between the engine oil pump's drive shaft and the pump's rotor was not within specification. As a result, the pump's driveshaft could separate from the rotor.

Why it matters: Separation of the pump's driveshaft from the rotor could lead to a sudden loss of oil pressure causing the possibility of complete engine failure, resulting in an engine stall-like condition, increasing the risk of a vehicle crash.

The fix: Bmw will notify owners, and dealers will replace the oil pump, free of charge. The safety recall began on November 30, 2012.
