4 recalls covering model years 2018, 2019, 2020, 2021. To check whether your vehicle is affected, look up your 17-character VIN at nhtsa.gov/recalls — a recall may apply only to some vehicles of a given year.
Certain Mazda3, Mazda6, Mazda2, MX-5, CX-3, CX-5 and CX-9 vehicles have a part inside the low-pressure fuel pump — the small spinning piece that pushes fuel toward the engine — that can crack and warp. When that happens the pump can quit working, and the engine can stall, meaning it shuts off while you are driving. Mazda dealers will replace the fuel pump at no cost to you.
These CX-9s have a second-row bench seat that splits 60/40. On the left-hand section, the seat may slide forward unexpectedly during a crash instead of staying put. Because the seat belt anchors to the seat, that movement pushes extra force onto whoever is buckled in there. The vehicle does not meet the federal safety standard for seat belt anchorages. Dealers will replace the internal parts of the affected second-row seats free of charge.
Certain 2019 CX-9 SUVs came with Sumitomo Falken ZIEX CT50 A/S tires in size P255/50R20, date code 1619, that may have been made with the wrong rubber mixture. On these tires the tread — the thick outer layer that grips the road — can peel away and come off while you are driving. Losing tread at speed can make the vehicle wobble or pull hard to one side, and flying rubber can strike nearby cars.
A wiring harness — the bundle of wires that carries electrical signals around the vehicle — may not pass signals properly in some 2018 CX-9s. When that happens, the front passenger airbag can be switched off, the turn signals can stop working, and the engine may not start. A passenger airbag that does not go off in a crash leaves that person far less protected, and without turn signals other drivers cannot tell where you are heading. Dealers will repair the harness free of charge.
