Federal regulators have lowered their estimate of potentially defective Takata Corp. air bags on U.S. roads.
The National Highway Traffic Safety Administration says approximately 23.4 million driver and passenger air bag inflators on 19.2 million vehicles are being recalled and need to be replaced. That's lower than its initial estimate of 34 million inflators.
The agency says some air bags from multiple recalls were counted twice. Takata also included some air bags sold overseas in numbers it gave to the government.
The agency says 4.4 million air bag inflators have already been replaced.
