Overview

2015 BMW M6

The 2015 BMW M6 is a high-performance grand tourer that delivers exhilarating driving dynamics. Its potent 4.4-liter V8 engine, paired with a smooth Automatic (AM-S7) transmission, provides ample power for spirited driving. While the M6 boasts a 'Good' public reliability verdict, a high TSB count of 165 suggests underlying complexity. Buyers should be aware of two significant recalls concerning the driveshaft and the third brake light. The absence of consumer complaints, despite these recalls, warrants cautious interpretation given the potential severity of the issues.

Critical Failure Risk

Recall addressed potential inadequate welding. Premature wear or failure of universal joints or center support bearings can occur.
