What's wrong, in plain English

BMW is recalling certain 3 Series, 4 Series and 2 Series Gran Coupe cars, including the M340i and M440i. The software in the car's audio receiver control unit may not properly sound the audible warning that reminds the driver to buckle their seat belt. Because that warning does not work as it should, these vehicles do not meet the federal safety standard covering occupant crash protection.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to see if your car is included. 2. Contact a BMW dealer to schedule the software update, or call BMW customer service at 1-800-525-7417. 3. The repair is free of charge.

Where do I find my VIN, and what do I tell the dealer?

Your VIN is the 17-character code on the lower left of the windshield, on your registration and usually on your insurance card. Enter it at nhtsa.gov/recalls to see whether this recall is still open on your car. When you call the dealer, say you have an open safety recall and give them NHTSA campaign number 23V584000.
