BMW X3 battery cable connection can overheat

NHTSA campaign 25V109000 · Reported 2025-02-21 · BMW of North America, LLC

critical How serious is it? About this label

This is serious because the engine can stall in traffic and the cable can catch fire, so get it inspected as soon as possible; BMW has not told owners to stop driving or to park outside.

What's wrong, in plain English

The connection between the positive battery cable and the starter-generator on certain 2025 X3 30 xDrive vehicles may not have been tightened properly at the factory. A loose connection can heat up while you drive. That overheating can make the engine shut off unexpectedly, and it can also start a fire under the hood. A dealer will check the connection and tighten it, or replace the cable and starter-generator if that is needed.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to confirm your X3 is included.
2. Call your BMW dealer now to book the inspection, or contact BMW customer service at 800-525-7417 (owner letters were mailed June 5, 2025).
3. Have the dealer tighten or replace the connection — the repair is free.
