The vehicles were subject to previous recalls where front passenger airbag inflators were replaced with new Takata-produced, non-desiccated airbag inflators as a remedy.
A safety defect may arise in the Takata inflators due to propellant degradation occurring after prolonged exposure to high absolute humidity and high temperature cycling.
Activation of such inflators may result in an airbag inflator rupture, causing sharp metal fragments to pass through the airbag and spray directly at the driver and passengers, increasing the risk of serious injury or death.
What to do
Toyota dealers will replace the front passenger airbag inflator or the airbag assembly with an improved one produced by non-Takata suppliers at no cost.
The recall is expected to begin in early January 2019
