The 2008 BMW M3 has 5 recalls, the most serious being a driver's frontal airbag inflator that can rupture and send metal fragments into the cabin, posing a risk of serious injury or death to the driver and other occupants.
A separate electrical concern involves the positive battery cable connection at the fuse box, which can degrade over time and cause an intermittent loss of power, potentially stalling the vehicle while driving. The heating and air conditioning wiring and its electrical connectors can overheat and melt, raising the risk of a fire even when the car is parked and unattended. On the drivetrain side, this recall only affects vehicles equipped with the optional double-clutch transmission: the transmission software can trigger an unintended multi-stage downshift during rapid deceleration, which can stall the engine at low speeds and increase the risk of a crash.
