BMW 4 SERIES Recalls

The BMW 4 Series has 6 recalls spanning 2015 through 2022, with the most serious being a 2021 model year issue where the 48-volt battery cable bolts connecting to the starter-generator can be improperly installed, causing the electrical connections to overheat and potentially start a fire. The 2022 model year has a separate electrical concern: vehicles that had a body control module replaced at a dealer may have received a unit with a programming error that disables automatic door locking, allowing a door to swing open in a severe crash. On 2018 models, one or both front seatbelt retractors can contain an incompatible internal mechanism that prevents the belt from locking during a crash, reducing restraint when it matters most. Going back to 2016, M3 and M4 trims have a driveshaft flange that can disconnect, causing an abrupt loss of drive power. The 2015 M3 and M4 have a related but distinct issue: an unlubricated driveshaft slip-joint can seize over time and also result in a loss of drive power. The 2015 model year also has a recall where the airbag control module was programmed with incorrect software, which can alter the timing of driver's airbag deployment in a crash.
