BMW and MINI crankshaft sensor fault can stall engine

NHTSA campaign 18V465000 · Reported 2018-07-12 · BMW of North America, LLC

high How serious is it? About this label

Serious — a sudden stall increases the risk of a crash; BMW has not told owners to park the vehicle, but the free sensor replacement should not be put off.

What's wrong, in plain English

A sensor that tracks the position of the engine's crankshaft was built with the wrong software inside it. Because of that, it may not read the engine correctly, and the engine can suddenly stall. A stall can happen while you are driving, leaving you without power in traffic. Dealers will replace the crankshaft sensor for free. BMW first announced this for one model and later expanded it to thousands more BMW and MINI vehicles.

What you should do

1. Look up your VIN at nhtsa.gov/recalls to see if your BMW or MINI is on the expanded list. 2. Contact your BMW or MINI dealer, or BMW customer service at 1-800-525-7417, to book the repair. 3. Have the crankshaft sensor replaced at no charge.
