BMW i4 and 3- and 4-Series doors may not auto-lock

NHTSA campaign 23V118000 · Reported 2023-02-23 · BMW of North America, LLC

medium How serious is it? About this label

Doors that do not lock as intended while the vehicle is in motion may open during a crash, increasing the risk of injury. The notice does not tell owners to stop driving.

What's wrong, in plain English

This recall covers cars that had an electronic control module replaced during a service visit. The replacement part may have been loaded with the wrong software, and that mistake can stop the automatic door locking feature from locking the doors once you start driving. Doors that are not locked are more likely to come open in a crash, which can let someone be thrown out of the car. A dealer reloads the correct software.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your car is one of the affected vehicles.
2. Ask your BMW dealer for the free control module software update; letters were mailed April 10, 2023.
3. Until it is done, lock the doors by hand after everyone is in. BMW customer service: 1-800-525-7417.
