BMW is recalling certain model year 2013 M5, M6 Coupe, and M6 Convertible vehicles, manufactured from July 19, 2012, through September 11, 2012. 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.
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.
BMW will notify owners, and dealers will replace the oil pump, free of charge. The safety recall is expected to begin during October 2012. Owners may contact BMW at 1-800-525-7417.
