More cars could soon join the list of recalls over exploding airbags.

Until now, the nearly 8 million vehicles under recall have been concentrated in warmer states with humid climates.

But there is increasing pressure to expand the recall nationwide.

The recall started last year, and it expanded earlier this year.

The issue gained increasing attention earlier this month as Toyota and the National Highway Traffic Safety Administration stepped up efforts to get car owners to replace their airbags.

At least four deaths and numerous injuries are linked to airbag parts that did not expand properly in an accident or exploded.

The list of affected makes include Honda, Toyota, BMW, Mazda, Mitsubishi, Subaru, Nissan, Ford and General Motors.

Japanese parts maker Takata manufactured the defective airbags.
