What's wrong, in plain English

Certain Buick Regal vehicles may lose power brake assist if there is a vacuum-power brake assist failure. A software error in the brake control module can cause this loss of assist. Without power assist, it takes more distance to bring the vehicle to a stop, which increases the risk of a crash. Because of this issue, these vehicles do not meet a federal safety standard for brake systems.

What you should do

1. Check your VIN at nhtsa.gov/recalls to confirm your vehicle is included.
2. Contact your Buick dealer, or call Buick customer service at 1-800-521-7300, to schedule the software update.
3. The repair is free.

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 22V465000.
