2021 Mazda CX9 recalls

Seats: mid/rear assembly · Seat belts: rear/other

NHTSA campaign 21V750000 · reported September 27, 2021 · Mazda North American Operations · 8,648 vehicles potentially affected

The 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."
The risk: A seat that slides forward during a crash can transfer excessive force onto a belted occupant, increasing their risk of injury.
The 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.
