MANUFACTURER: BMW of North America, LLC.

REPORT RECEIPT DATE: September 28, 2012

NHTSA CAMPAIGN ID NUMBER: 12V475000

NHTSA ACTION NUMBER: N/A

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.

NOTES:
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
