Derived from the 6-Series automobiles, the BMW M6 is a high-performance sports car that usually comes in two body styles: the coupe and the convertible. M6 owners should be aware of the common problems that they may come across so they can prepare themselves in the future. Here are some of them:
One of the most common complaints about the BMW M6 is related to its engine. Some of the 2013 M6 coupes and convertibles had engine oil pump problems due to a manufacturing process error, which may possibly separate the pump's driveshaft from the engine's rotor. This may have resulted to an increased crash risk and a potential engine replacement, which is very costly. BMW stopped deliveries and the owners of the M6 were asked to refrain from driving their cars until they were serviced. Only vehicles manufactured from July 19 to September 11, 2012 were included in the recall.
Another common trouble encountered with the BMW M6 is related it to its battery. The error was due to the M6's battery cable connection bolts that loosen over time. This resistance may cause overheating and electrical system problems. In March 2012, BMW recalled approximately 1.3 million vehicles worldwide. Aside from the 2007 - 2010 M6 models, the recall also included the 5-Series, 6-Series, and the M5. The National Highway Traffic Safety Administration noted that overheating may still take place even when the vehicles are not in use. Therefore, owners were requested to park their vehicles outside until the problem was solved.
In the 1980s, the frequent problems of the M6 were related to its cooling engine, service brakes, and suspension assembly. It was reported that a grinding noise came out from the differential clutch, especially during slow cornering. In the 2007 editions of the M6, most problems were related to its digital instrument panel, emission control, power train, and tires. It was reported that the gear indicator suddenly reverses when the engine is turned off with the gear selector. Also, there was an error in the software which caused incompatibility with the system's communication.
