Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2018 BMW M6 represents the fifth year of this generation (beginning circa 2013), and the data shows a clear maturation pattern: complaints dropped from 5 in 2014 to just 1 in both 2017 and 2018, while TSBs plummeted from 354 in 2013 to just 40 in 2018—the lowest level in the entire generation. The single 2018 complaint targeted steering, suspension, and vehicle speed control systems, with zero crash or fire complaints filed. Compared to 2017's 2 recalls, 2018 saw only 1 recall, suggesting BMW had resolved many earlier manufacturing issues by this point. The 2019 model year then showed further improvement with zero complaints, indicating the platform reached peak reliability around this timeframe. This makes the 2018 model year a strong candidate within this generation—it's late enough to benefit from the engineering refinements accumulated over five years, yet early enough to avoid the higher mileage and depreciation that come with later examples.
