Overview

2021 BMW M850i

The 2021 BMW M850i is a potent grand tourer that blends luxury with V8 power. For used car shoppers, its appeal lies in its performance and upscale interior. However, a significant recall concerning the integrated braking system demands buyer attention. While owner complaints are absent, this recall, impacting brake assist, is a critical factor in assessing the vehicle's long-term reliability and ownership risk. The presence of four recalls, including the braking system issue, suggests potential repair costs beyond routine maintenance.

Critical Failure Risk

A critical recall (21V062000) addresses a potential weld defect in the rotor and shaft of the integrated brake system. This can lead to separation during hard braking, causing a loss of ABS and braking assistance. The remedy involves replacing the entire integrated brake system.

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