Problem: BMW of North America, LLC (BMW) is recalling certain 2023 330i, 330i xDrive, M340i, M340i xDrive, M3, 330e, 330e xDrive, 430i Convertible, 430i xDrive, M440i, 2022-2023 430i, 430i xDrive, M440i xDrive, i4 eDrive40, and i4 M50 vehicles. During a service visit, a replacement electronic control unit (ECU) may have been installed with incorrect programming, which can cause the automatic door locking (ADL) function to not lock the doors as intended.
Risk: Doors that do not lock as intended while the vehicle is in motion may open during a crash, increasing the risk of injury.
Fix: Dealers will update the ECU software, free of charge. Owner notification letters were mailed April 10, 2023. Owners may contact BMW customer service at 1-800-525-7417.

Recall repairs are free at any authorised dealer. A recall listed here may already have been fixed on a particular car: enter its 17-character VIN at nhtsa.gov/recalls to see open recalls.

Recent owner complaints

EngineCrash
While parallel parking in a parking structure; my car accelerated full throttle backing up hitting the back wall ; then I tried going forward to straighten the car up, it accelerated full throttle forward hitting the front wall. I had an doctors appt. there and decided to still straighten car and I said if it goes full throttle again I would immediately put the car in neutral and turn the car off, which I did. Each time the car went full throttle I hit the brake pedal as hard as I can push. Leaving the car I tried locking the car with my key fob, it wouldn't lock or turn off the headlights, it caused the horn to keep beeping for no reason.
