What can fail
The engine starter relay can corrode, causing it to overheat and short circuit.
What the fix does
The 2020 BMW Z4 has 6 recalls, the most serious being two separate fire risks: a corroding starter relay that can short circuit and ignite, and a fuel tank weld that can fail and allow fuel to leak near ignition sources.
On the engine side, the Z4 M40i trim has a software issue where the engine management system can cut braking assist during startup, leaving the driver with only the unassisted mechanical pedal, which requires noticeably more force to slow the car. Two separate headlight concerns round out the visibility cluster: the headlamps can be adjusted horizontally, which can either throw glare into oncoming drivers' eyes or reduce the driver's own forward sightlines, and the headlight control units on some vehicles can fail outright, dimming or killing one or both headlights entirely. There is also a rearview camera recall where the camera display can go blank while reversing, leaving the driver with no view of what is behind the vehicle.
