Overview

2021 BMW M3

The 2021 BMW M3 is a potent sports sedan, delivering exhilarating performance for enthusiasts. However, used car shoppers must be aware of its recall history, particularly concerning the integrated brake system. While the car boasts a strong public reliability score, the critical brake recall and multiple seat belt recalls suggest potential systemic issues that require thorough verification.

Critical Failure Risk

A critical recall addressed potential separation of the rotor and shaft in the integrated brake system, which could lead to loss of ABS and braking assistance. While a recall remedy exists, ensuring its proper execution is paramount.

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