Sep 28, 2012 — Recall Campaign #12V475000

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.

The recall was influenced by the manufacturer with about 696 units affected.

Units affected:	696

Description:: BMW is recalling certain model year 2013 M5, M6 Coupe, and M6 Convertible vehicles, manufactured from July 19, 2012, through September 11, 2012.

2013 BMW M5 Complaints
I WAS DRIVING DOWN A HIGHWAY IN MY CITY WHEN I STARTED TO HEAR A SQUEAKY SOUND SORT OF LIKE A HAMSTER WHEEL. SHORTLY AFTER I STARTED TO HEAR LOUD METAL TO METAL CLANKING SOUND AND THE ENGINE FAILED WHILE IN TRAFFIC ON THE HIGHWAY. I WAS ABLE TO MANEUVER THE VEHICLE TO SAFE LOCATION ON THE SIDE OF THE ROAD WITH BEING HARMED BUT THE POSSIBILITY OF A MAJOR WRECK WAS POSSIBLE DUE TRAFFIC VOLUME AND SPEED. I HAVE ATTACHED THE MECHANICS QUOTES FOR REPAIR OF ENGINE FAILURE DUE TO IMPROPER AND QUICK OIL PRESSURE FAILURE. A ROD WAS SEIZED TO THE CRANKSHAFT AND THEN THE BEARING WAS DESTROYED AND METAL WAS SENT THROUGH THE ENGINE. ONE QUOTE IS FOR A REBUILD OF THE ENGINE IF IT IS POSSIBLE ONCE BREAKING THE ENGINE DOWN TO CONFIRM CONDITION AND THE OTHER IS FOR A MOTOR REPLACEMENT WITH A 40K MOTOR. BMW QUOTE FOR A NEW ENGINE REPLACEMENT FOR THE ENGINE ALONE IS $51,000 PLUS LABOR. THE MECHANIC AND I BELIEVE THIS VEHICLES ENGINE AND OIL PUMP COULD HAVE BEEN BUILT DURING THE TIME OF THE RECOGNIZED BMW RECALL BEING THAT THE VEHICLES MANUFACTURING DATE WAS IN OCTOBER OF 2012 AND THE RECALL WAS FOR A 3 MONTH PERIOD ENDING SEPTEMBER 11, 2012. I AM AN ENGINEER WORKING FOR TOYOTA MANUFACTURING OF NORTH AMERICA AND I AM AWARE OF HOW MOST RECALLS CAN COME TO BE. I AM ALSO AWARE THAT VEHICLES CAN BE KICKED OUT OF THE MANUFACTURING PROCESS FOR OFFLINE REPAIRS AT ANY GIVEN TIME DURING THE BUILD PROCESS THUS MAKING THE WHOLE CARS MANUFACTURING DATE LATER THAN MANY COMPONENTS OF THE VEHICLE INCLUDING THE ENGINE AND OIL PUMP. I WOULD LIKE FOR BMW TO RECOGNIZE THIS ISSUE AND THE IMMEDIATE DANGER IT PUT ONE OF THEIR CUSTOMERS DUE TO A KNOWN ISSUE. PLEASE FEEL FREE TO CONTACT ME WITH ANY QUESTIONS OR CONCERNS YOU HAVE RELATED TO THIS UNSAFE FAILURE. THANK YOU FOR YOUR TIME.
