Toyota recalled the vehicles in April last year after discovering the front passenger airbag may have been assembled with improperly manufactured propellant wafers.
The original recall notice explained that in the event of a crash “the inflator may rupture and cause the front passenger airbag to deploy abnormally, increasing the risk of injury to the occupant”.
Toyota says only a small number of vehicles recalled last year had their airbag inflators replaced, though the updated repair process will see the front passenger airbag inflator replaced in all affected vehicles.
Customers that had the part replaced under last year’s recall will not be required to take their cars back to dealerships this year.
Affected customers will be notified by mail and asked to make an appointment at their Toyota dealership when parts become available.
The airbag inflator will be replaced free of charge and will take between one and 2.5 hours for Toyota vehicles and about 5.5 hours for Lexus models.
