U.S. auto safety regulators are determining whether 70 million to 90 million more Takata Corp. air-bag inflators should be recalled.

Continental Automotive Systems Inc. said five million vehicles need to be recalled to fix their air-bag control units, adding to the challenges for an auto industry already struggling to replace millions of faulty air bags made by Takata Corp.

Takata President Shigehisa Takada made his first public apology for the eight deaths and hundreds of injuries related to the companys air bags.

The safety crisis plaguing the global automotive industry deepened as Japans three biggest carmakers said they would recall more than 11 million additional vehicles because of faulty air bags that can shoot shrapnel at motorists.

The safety crisis involving faulty air bags that shoot shrapnel deepened after Toyota and Nissan added more than 6 million vehicles to their global recalls, with Honda planning to expand a call back.

Car-maker will recall about 768,000 vehicles worldwide in two separate actions to fix a fire risk and hood that may open during driving.

Honda Motor Co. President Takanobu Ito, beset by record recalls last year, told suppliers the carmaker will examine operations to improve quality and safety standards.

Honda Motor Co. and Nissan Motor Co. recalled almost 3 million vehicles to repair flaws in Takata Corp. air bags, adding to a call back by Toyota Motor Corp. earlier this month.
