2010 Mazda CX-9 Recalls
The passenger frontal air bag assembly is deployed by an inflator which contains propellant that makes the air bag deploy. This propellant may degrade over time, especially when exposed to humidity and temperature cycling. As a result, the inflator may rupture on deployment, which can send metal shrapnel through the air bag, striking vehicle occupants. This could result in serious injury or death.
A key front suspension component called a ball joint may corrode internally, resulting in possible separation from the vehicle. If the ball joint comes apart, loss of steering would occur.
The heated seats are made up of wiring, switches, and the element, which is the part that gets hot in order to heat the seat. Mazda has found that there is a possibility for the seat heater circuit to overheat and cause damage to the seat cushion and a risk of fire.
