The weld seam of the integrated transmission control unit's cover may not have been manufactured properly, which could allow automatic transmission oil to leak into the transmission control unit.
- Consequence
- Transmission oil that leaks into the control unit can lead to a seizure of the transmission gears, causing a sudden loss of drive power and increasing the risk of a crash.
- Remedy
- Dealers will replace the transmission mechatronics module and the automatic transmission fluid, as necessary, free of charge. Owner notification letters were mailed January 26, 2024. Owners may contact BMW customer service at 1-800-525-7417.

When the digital key is removed from the vehicle, the Electronic Control Unit (ECU) software may still allow the power windows and sunroof to be closed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 118, "Power-operated Window Systems."
- Consequence
- Unintentionally closing the windows or sunroof without the key present can increase the risk of injury to occupants inside the vehicle.
- Remedy
- Dealers will update the software for the Electronic Control Unit (ECU), free of charge. In addition, the digital key function via cellular service and Wi-Fi capability will be deactivated until the vehicle is updated with new software. Owner notification letters are expected to be mailed April 11, 2023. Owners may contact BMW customer service at 1-800-525-7417.
