Toyota and Nissan launched massive global expansions Wednesday of their recalls of potentially deadly vehicle air bags made by Japan’s Takata.

The twin automakers’ actions add more than 6.5 million vehicles to the recalls that already encompassed millions of vehicles from multiple automakers in the U.S. — and around the world.

Toyota’s and Nissan’s moves show how the troubles of Japanese auto supplier Takata, which has also drawn intense scrutiny from U.S. regulators, continue to deepen. It also indicates that Honda, which has borne the brunt of trouble from air bags because of its dependence on Takata, isn’t alone.

Six fatal accidents involving Takata air bags have occurred in Hondas — five in the U.S. and one in Malaysia. The accidents are caused when a Takata inflator spews plastic and metal debris on passengers after accidents.

Nissan plans to recall 1.5 million more vehicles, Bloomberg News reported. Toyota will recall 5 million. The recalls are in addition to the more than 17 million vehicles subject to earlier recalls. Read more on USA Today.
