On certain vehicles, exposure to moisture over time could cause the driver-front airbag not to inflate properly in a crash. In some cases, this could cause an airbag not to fully inflate, while in others it could cause it to deploy with more force than normal. It could also cause the inflator to rupture. If the airbag inflator ruptures, small pieces of metal could be propelled toward vehicle occupants or cause damage to the airbag and prevent its proper function.
In a crash requiring an airbag deployment, the driver-front airbag may not inflate properly or the inflator could rupture. This could create a risk of injury.
Toyota will notify owners by mail. The corrective actions for this recall are under development.
