A problem with Japanese-made air bags could lead to the largest recall of any product in U.S. history.
Federal regulators announced Tuesday that Takata is declaring 34-million vehicles defective because its air bags could explode.
There have already been about 17-million vehicles recalled in the U.S. because of defective air bag inflators made by the Japanese company.
Six deaths and more than 100 injuries have been linked to the problem.
