What's wrong?
The left-side second-row seat in the 2020-2021 Mazda CX-9 is the bench section behind the front row on models with the 60/40 split bench setup. Its slide track lets the seat move for adjustment, and its lock is supposed to hold the seat in place during a crash while the seat belt anchors restrain the passenger.
On included CX-9 vehicles, internal parts in the seat slide mechanism were not manufactured correctly. When a belted passenger loads the seat belt mounts during a collision, that force can release the lock. The left-side second-row seat can then slide forward instead of staying fixed, which means the seat and belt are not holding the passenger in the designed position.
This defect does not give the driver or passenger a sound, warning light, or loose-seat feel before it happens. There is no warning sign before failure.
Who's affected?
Covers the 2020 and 2021 model years, with the left second-row seat tied to both the seat assembly and rear seat belt.

What's the safety risk?
In a crash, an affected seat can slide forward and transfer excessive force to a belted occupant, increasing the risk of injury. There is no warning sign before the seat moves, so have the recall completed soon if your VIN is included. Repair is free at any franchised Mazda dealer.
What should I do?
- Check your VIN to confirm your 2020-2021 Mazda CX-9 is included in this recall.
- Contact a franchised Mazda dealer to schedule the free second-row seat internal-parts replacement that fixes the left-side seat sliding forward during a crash.
- Bring the recall notice if Mazda mailed one. If not, reference recall number 21V750 when you call.
- Keep passengers out of the left-side second-row seat until the repair is complete.
What happens at the repair
At the dealer, a Mazda technician replaces the internal parts in the affected second row seats. The recall repair is free, and parts and labor are covered. Mazda is not offering a separate reimbursement program because the subject CX-9 vehicles are covered under the vehicle warranty. If you already paid for a related seat repair, ask the Mazda service desk how the existing warranty applies to that prior work.
