With new information from the NTHSA and Takata, Toyota has announced it will recall 1.6 million vehicles marketed in the United States of America.
Earlier this month, Takata Corp said it was declaring another 35 million to 40 million US inflators defective at the urging of USA regulators, a move that more than doubles the number of inflators recalled.
The action expands what was already the biggest automotive recall in US history.
The decision affects some models of Corollas, Lexus and Scion made between 2006 and 2011. Since then many auto manufacturers who used Takata's inflators have recalled millions of their cars to replace the faulty airbag inflators and now Mercedes-Benz is joining that list.
The recall expansion will be announced in phases based on the age of vehicles and where they are registered.
As with other Takata airbag recalls, the problem centres around the airbag's inflator casing which could rupture as the airbag deploys.
Malfunctioning Takata air bag inflators can explode with too much force, sending shrapnel into vehicles.
Toyota will notify all known owners of the Scion, Lexus, and Toyota models through first class mail. Depending on the model, dealers will replace the front passenger air bag inflator or the front passenger air bag assembly.
