The 2007 Mazda CX-9 has 8 recalls, the most serious being a passenger-side frontal airbag inflator that can rupture and send metal fragments into the cabin, posing a risk of serious injury or death.
The airbag concern covers several overlapping filings that all point to the same core problem: the propellant inside the passenger frontal airbag inflator can degrade over time, especially in high-humidity and high-temperature environments, causing the inflator to rupture or deploy with far more force than designed. One filing specifically covers vehicles sold or registered in warm, humid states and territories including Florida, Hawaii, Texas, and Puerto Rico, where heat and moisture accelerate the degradation. Another filing covers vehicles where prior recall repairs used replacement inflators of the same flawed design, meaning the earlier repair did not fully resolve the issue. Any of these scenarios can result in metal fragments striking occupants in the front cabin, and the danger is present whether or not the airbag is triggered by an actual crash.
On the suspension side, the front lower ball joints can corrode when water works into the joint fitting. Over time, that corrosion can cause the lower control arm to separate entirely from the ball joint, which would result in sudden, unpredictable loss of steering control while driving. This risk applies to vehicles that see road salt or moisture exposure, though the recall is not limited to those regions.
There is also a concern with the power-adjustable front seats on certain trims equipped with a memory-position function. The wiring harness that runs through the seat can chafe against

What can fail
The front suspension ball joint can separate from the lower control arm due to saltwater corrosion, which could cause loss of steering control and increase crash risk.
What the fix does
Dealers will replace the lower control arm with an updated version.

What can fail
Water can leak into the front suspension ball joint fittings, causing them to corrode and potentially fail.
What the fix does
Dealers will replace both the left and right lower control arms at no charge.

What can fail
The wiring harness for power-adjustable seats with memory function can wear through from rubbing. Exposed wires may touch a metal bracket, causing an electrical short that can trigger unexpected, uncontrollable seat movements.
What the fix does
Dealers will inspect and secure the seat harness. If needed, they will repair the covering or replace the harness.
