    Safety restraint issue

    SEATS:MID/REAR ASSEMBLY

    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."

    Consequence

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

    Remedy

    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.

What the ratings mean

NHTSA gives the 2021 Mazda CX-9 5 out of 5 stars overall. NHTSA does not publish enough comparable results for this class and year to rank it against peers.

NHTSA published results for every NCAP test in this program, so the overall star rating rests on a complete set of crash and rollover results.

NHTSA's dynamic test put this vehicle's rollover probability at 15.9% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.
