The 2020 BMW Z4 has 6 recalls, the most serious being two separate fire risks: a fuel tank weld that can fail and allow fuel to leak, and a starter relay that can corrode, overheat, and short circuit.
On the engine side, a software issue during engine start can cause loss of brake assist, leaving full manual braking available but requiring more pedal effort to stop. There are also two headlight concerns: the headlamps can be adjusted horizontally in a way that creates glare for oncoming drivers or reduces the driver's own visibility, and the headlight control units on certain trims can fail and cause one or both headlights to go dark. Rounding out the list, the backup camera can fail to display an image when reversing, removing the view behind the vehicle.
