7 recalls across 6 model years
The BMW 4 Series has 7 recalls spanning 2015 through 2023, with the most serious being a 2023 model year issue where transmission oil leaks into the transmission control unit, causing the gears to seize and the vehicle to suddenly lose drive power.
On the 2021 model year, improperly installed bolts on the 48-volt battery cable connections to the starter-generator can cause those connections to overheat and start a fire. The 2022 model year has a separate electrical concern: vehicles that had the 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.
The 2018 model year has a seatbelt retractor issue where a component inside one or both front seatbelt retractors can be incompatible with the locking mechanism, preventing the belt from locking in a crash and reducing restraint protection. Going back to the 2016 model year, M3 and M4 trims have a driveshaft flange that can disconnect, cutting drive power without warning. The 2015 model year has two issues: M3 and M4 models have a driveshaft slip-joint that can fail over time from insufficient lubrication, again resulting in loss of drive power, and a separate airbag software error can cause the driver's front airbag to deploy with incorrect timing in a crash.
