Recall Alert: 2013 BMW M5 and M6
The affected vehicles were manufactured from July 19 through Sept. 11 (check your vehicle's build date on a sticker on the driver-side doorjamb); a manufacturing defect could cause the oil pump's driveshaft to separate from the rotor. This could lead to a sudden loss of oil pressure and the engine could stall, increasing the risk of a crash.
BMW will notify owners later this month, and dealers will replace the affected parts free of charge. Owners can call BMW at 800-525-7417 or NHTSA's vehicle safety hotline at 888-327-4236 for more info.
