What's wrong, in plain English

Mazda is recalling certain CX-30 and CX-50 vehicles because the anti-lock brake system's hydraulic control unit may become damaged. If this happens, the brakes may not work as well as they should, giving the vehicle reduced braking ability. That means it could take a longer distance than normal to slow down and come to a complete stop when needed.

1. Check your VIN at nhtsa.gov/recalls.
2. Contact a Mazda dealer at 1-800-222-5500, option 6.
3. The inspection and any needed repair are 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 23V275000.
