BMW i4, iX and i7 can lose drive power suddenly

NHTSA campaign 22V944000 · Reported 2022-12-20 · BMW of North America, LLC

critical How serious is it? About this label

A sudden, unannounced loss of drive power can cause a crash, so get the software update as soon as you can; the notice does not tell owners to park the vehicle.

What's wrong, in plain English

The software running the computer that controls the big high-voltage battery can cut off electrical power. If that happens while you are driving, the vehicle can suddenly lose the power that turns the wheels — it simply stops pulling. Losing power without warning in traffic, on a highway, or partway through a turn leaves you very little time to react and steer over to the side of the road.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your vehicle is on the list.
2. Contact your BMW dealer to schedule the update, or call BMW customer service at 1-800-525-7417; owner letters were expected February 10, 2023.
3. The dealer updates the high-voltage battery control software free of charge.
