Overview

2021 BMW M8

The 2021 BMW M8 is a formidable grand tourer, blending aggressive performance with luxury appointments. Under the hood, its 4.4-liter V8 engine paired with an 8-speed automatic transmission and all-wheel drive delivers exhilarating acceleration. However, potential buyers should be aware of a significant recall concerning the integrated braking system, which could impact reliability and ownership confidence. Despite the absence of owner complaints in NHTSA data, this critical recall necessitates careful scrutiny of the vehicle's service history and braking components. High fuel costs are also a consideration for this performance-oriented machine.

Critical Failure Risk

A critical recall (21V062000) addresses potential weld integrity issues in the integrated brake system's rotor and shaft. This can lead to a loss of ABS and braking assistance during hard braking.

Early detection can help you avoid a $2,000-$4,000 repair.
