Potential Number of Units Affected: 696
Summary: 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.
Consequence: 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.
Remedy: 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.
