The 2015 BMW M3 has 3 recalls, the most serious involving a driveshaft slip-joint that can seize and cut power to the rear wheels, and rear sub-frame bolts that can loosen and compromise handling control. The driveshaft issue stems from a missing grease fill in the slip-joint, which can cause the joint to fail and leave the car unable to move, raising crash risk. The sub-frame concern applies to vehicles that received a prior rear differential service, where bolts may have been reused rather than replaced; as they loosen, the rear suspension loses its secure mounting point and handling becomes unpredictable. There is also a side airbag recall: the inflator can rupture and send metal fragments into the cabin or outward, raising the risk of injury to occupants or bystanders.
