The 2006 Toyota Corolla Matrix has 4 recalls, all involving the front passenger airbag, with the most serious being a Takata inflator that can rupture and send metal fragments into the cabin, potentially causing serious injury or death.
The remaining recall affects vehicles where the front passenger airbag assembly was replaced under a prior recall. That replacement inflator may not unfold correctly when it deploys in high heat, leaving the airbag underinflated in a crash and reducing its ability to protect the occupant. Prior repair attempts did not fully resolve the issue for all affected vehicles, so owners who have already had airbag work done under an earlier recall may still be affected.
