The 2021 BMW M3 has 3 recalls, the most serious being a brake system fault that can reduce braking assistance and disable the anti-lock brake system, raising the risk of a crash.
The remaining two recalls both involve the seatbelts. In one, a bolt securing the front seatbelt assembly to the vehicle frame was not tightened to specification, meaning the belt may not hold an occupant in place during a crash. In the other, the seatbelt retractor can fail to function correctly in a collision, which also compromises how well the belt restrains the occupant. Together, these two issues mean the front seatbelts on certain M3s may not perform as expected when they are needed most.
