BMW will be contacting drivers of certain 2013 BMW M5 and 2013 BMW M6 coupe and convertibles high performance vehicles with twin turbocharged V8 engines. According to reports filed with the National Highway Traffic Safety Administration (NHTSA) certain vehicles may be equipped with an oil pump that may fail because of a problem with the manufacturing process. The oil pump drive shaft could separate from the rotor starving the engine of oil. If the vehicle is not pulled over immediately, the engine will overheat and eventually seize. BMW will be notifying customers of the the problem starting this month, and will replace the oil pump free of charge. Owners wanting more information may contact BMW at 1-800-525-7417.
