Summary
The BMW M3 has 13 recalls spanning 1990 through 2017, with the most serious recent issue being a Takata passenger airbag inflator defect on 2001-2006 models where the inflator can rupture in a crash and send metal fragments into the cabin.
The 2015-2017 model years carry two structural and drivetrain concerns. On 2015-2017 vehicles, rear subframe bolts that were reused during a prior differential service can loosen over time and degrade handling control. On 2015-2016 models, the driveshaft slip-joint can run dry of grease, wear through, and cause a sudden loss of drive power to the rear wheels, leaving the vehicle unable to move. The 2008-2012 M3 has a battery positive cable connection at the fuse box that can degrade and cause the car to lose electrical power and stall. The dual-clutch transmission on 2008 M3 models optionally equipped with that gearbox can trigger an unintended multi-stage downshift during rapid deceleration at low speed, stalling the engine.
Going further back, the 1998 M3 has a side airbag wiring issue where the bag can deploy without any side impact, and the battery safety terminal can also activate and cut power to the starter. The 2003 model has a power window anti-pinch system that can fail, allowing a closing window to trap a hand or arm. On 2001 models, two screws securing the parking brake cable bracket can loosen and fall into the brake drum, leaving that side's parking brake inoperable.
The 1996 model has a throttle and cruise control cable bushing that can crack, allowing the throttle to stay partially open and preventing the car from decelerating normally. The 1995 model has two separate issues: a brake light switch that can stick either on or off regardless of pedal position, and crash test force levels on unbelted occupants that exceed federal safety limits, raising injury risk in a collision. The 1994 model has a heater core end piece that can crack under elevated coolant pressure and suddenly expel hot coolant into the cabin. The 1990 model has a similar cooling system pressure concern where failed components can cause coolant hose leaks or radiator failures under overpressure conditions.
