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.

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.
