WASHINGTON, D.C. - Under pressure from federal regulators, Honda is expanding a recall of driver's side air bags to all 50 states.

The air bags, made by Japanese supplier Takata Corp., can explode with too much force, sending metal shrapnel into the passenger compartment.

Takata insists that current recalls covering 8 million U.S. cars in high-humidity areas are sufficient. But the National Highway Traffic Safety Administration wants the recalls expanded nationwide after some incidents outside the high-humidity zones.

Rick Schosteck, Honda's executive vice president for North America, told House lawmakers Wednesday that Honda will expand the regional recall it began in June, but will continue to prioritize high-humidity areas.

He also said Honda is working with other air bag manufacturers to make sure it has enough parts.

Drivers can find out if their vehicles are part of the recall by using a search tool on SaferCar.gov. The recall ID is 14V351. 

The NHTSA posted a list of recalled Honda vehicles late last month:

2001 - 2007 Honda Accord

2001 - 2005 Honda Civic

2002 - 2006 Honda CR-V

2003 - 2011 Honda Element
