What's wrong, in plain English

Mazda is recalling certain CX-30 vehicles. When the power liftgate — the rear hatch that opens and closes by itself — is fully open, it may partially come down on its own if the vehicle is parked facing uphill on a slope. Dealers will update the software that controls the liftgate and check the serial number of the liftgate drive unit, replacing that part if needed. The work is done at no cost to the owner.

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 repair, 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 21V086000.
