The 2009 Mazda CX-9 has 6 recalls, the most serious being a passenger-side front airbag inflator that can rupture and send metal fragments into the cabin, causing serious injury or death.
This airbag issue has been the subject of multiple recall campaigns, including one specifically targeting vehicles where prior replacement inflators of the same flawed design were installed and need to be replaced again. Vehicles that have been registered in high-humidity states and territories, including Florida, Texas, Hawaii, and others in that climate zone, are covered by additional filings because prolonged heat and moisture accelerate the risk of rupture. In short, the passenger frontal airbag inflator on this vehicle represents an ongoing and serious hazard that prior repair attempts did not fully resolve for all affected vehicles.
On the chassis side, the front lower ball joints can allow water to seep into the joint fitting and corrode the connection over time. If the corrosion progresses far enough, the lower control arm can physically separate from the ball joint while driving, leaving the driver with no meaningful steering input and a high risk of losing control of the vehicle.
The remaining recall involves the wiring harness that runs beneath the front seat on vehicles equipped with power-adjustable seats with a memory function. The harness can get pinched or worn against a metal bracket on the front of the seat cushion, potentially triggering uncontrolled seat movement while driving, which can interfere with the driver's ability to reach the pedals or maintain their position at the wheel.
