The 2014 BMW M4 has 2 recalls, both involving airbag inflators that can rupture or explode and send sharp metal fragments into the cabin, raising the risk of serious injury or death.
One recall covers the side and window airbags, where a faulty inflator can rupture and propel metal fragments either into the cabin or outward through the vehicle's body. The other affects the driver's frontal airbag inflator, which can explode with enough force to strike the driver or other occupants with metal debris. Both issues are serious and affect the airbag systems most likely to deploy in a crash.
