What's wrong, in plain English

Mazda is recalling certain Mazda3 vehicles. The Smart Brake System, which brakes on its own to avoid hitting something, can wrongly sense an object while you are driving and bring the car to a sudden stop. Dealers will update the software for this system. Vehicles built on certain dates will also get an instrument cluster software update or a new cluster, along with a replacement owner's manual. All of this work is free.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your vehicle is included.
2. Contact a Mazda dealer to schedule the update, or call Mazda customer service at 1-800-222-5500, option 4.
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 19V907000.
