NHTSA Recall 12V475000
Filed by BMW of North America, LLC. Component: Engine And Engine Cooling. Reported 2012-09-28. An estimated 696 vehicles are affected. Recall repairs are free at any authorized dealer.
Defect
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.
Risk
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.
What the manufacturer will do
BMW will notify owners, and dealers will replace the oil pump, free of charge. The safety recall began on November 30, 2012. Owners may contact BMW at 1-800-525-7417.
