SEATS:MID/REAR ASSEMBLY

21V750000 · September 27, 2021

The defect
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 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.

TIRES
All 4 of my BH255/50R20 XL 109v NOKIAN WR G4 vehicle tires are exhibiting abnormal tread degradation and excessive sidewall cracking. The tire defect includes a circumferential crack along the top of all 4 tires, where the top of the tire's sidewall and tread base meet. Upon tire inspection, the structural integrity and safety of these tires with continued usage is questionable. The tires in question are only 26 months old and have approximately 31K miles of usage.

NHTSA complaint 11721291. Filed by an owner and not verified by NHTSA or by us.

UNKNOWN OR OTHER
The information screen is getting 'spider cracks" spreading across the face and turning opaque making the information unreadable. Mazda is apparently aware of this defect and issued a TSB for earlier models. Dealers were unhelpful and quoted $1000 - $3000 to repair depending on the VIN.

Where these numbers come from

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
