The 2013 Mazda6 has 4 recalls, the most serious being a Takata airbag inflator that can explode and send metal fragments into the cabin, posing a risk of serious injury or death to the front passenger.
Corrosion is also a concern on vehicles registered in certain Midwestern and Northeastern states: rust can weaken the mounting point for the passenger-side lower control arm, which can cause unexpected changes in steering alignment and raise the risk of a crash. On the door hardware side, mounting screws on the door latch can work loose over time; if all three screws become loose enough, the latch may not hold and the door can swing open while driving.
