Eight automakers are recalling an additional 12 million vehicles in the United States to replace potentially faulty front passenger air bag inflators made by Takata Corp., the U.S. road safety regulator said Friday.

Honda Motor Co. is recalling the largest number of vehicles among the eight — 4,506,505 units — bringing the total number of cars recalled by the Japanese automaker in the United States to about 16.5 million, the U.S. National Highway Traffic Safety Administration said.

In addition, Toyota Motor Corp. is recalling 1,654,713 units, Mazda Motor Corp. 731,628 units, Nissan Motor Co. 402,450 units, Fuji Heavy Industries Ltd. 383,101 units and Mitsubishi Motors Corp. 38,628 units. They include vehicles sold under other companies' brands.

Fiat Chrysler Automobiles N.V. is recalling 4,322,870 units, including Mitsubishi Motors-brand pickup trucks, while Ferrari N.V. is recalling 2,820 units, according to the NHTSA.

The latest actions are part of the up to 40 million air bag inflators NHTSA ordered Takata to recall on May 4 amid concerns of potentially deadly ruptures.

Some Takata air bag inflators have ruptured and sprayed metal fragments at passengers. Takata-made inflators have been linked to more than 10 deaths worldwide.
