What's wrong, in plain English

On some vehicles, one or both front seats may be missing the bolts that attach the back of the seat to the vehicle. Without these attachment bolts, a seat with someone sitting in it can shift or move out of position if the vehicle is in a crash, which increases the risk that the occupant could be injured.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your vehicle is affected.
2. Contact Chevrolet customer service at 1-800-630-2438 or Buick customer service at 1-800-521-7300 to have your seat bolts inspected.
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 20V537000.
