What's wrong, in plain English

If the vehicle's body control module loses contact with the brake control module, the ABS warning light on the dashboard may not turn on even when the anti-lock brake system isn't working correctly. That means a driver might not realize there's a brake problem. Dealers will update the body control module software to fix this, free of charge.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your vehicle is included.
2. Contact a Chevrolet dealer or customer service at 1-800-222-1020.
3. The software update 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 20V319000.
