- Problem
- Mazda North American Operations (Mazda) is recalling certain 2020-2021 CX-9 vehicles equipped with 60/40 split bench second-row seats. The left-side second-row seat may unexpectedly slide forward during a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 210, "Seat Belt Assembly Anchorages."
- Risk
- A seat that slides forward during a crash can transfer excessive force onto a belted occupant, increasing their risk of injury.
- Fix
- Dealers will replace the internal parts of the affected second-row seats, free of charge. Owner notification letters were mailed November 4, 2021. Owners may contact Mazda customer service at 1-800-222-5500, Option 4. Mazda's number for this recall is 5221I.

- Electrical System — 4 owner reports. Test every window, lock, light, screen and USB port; check the battery age.
- Fuel/Propulsion System — 3 owner reports. Smell for fuel around the car and in the cabin, check that it starts easily when warm, and look at the oil dipstick for a fuel smell or rising level.

- Before you pay: service records, a history report and an independent inspection.
