Air bag recall spreads to more automakers

A recall of defective air bags is spreading to more manufacturers.

BMW, Chrysler, Ford, Honda, Mazda, Nissan and Toyota will all recall cars at the U.S. government's request because their air bag inflators could rupture. If that happens, the air bags might not work properly in a crash, and shards from the ruptured system could fly out and cause injury.

In each case, the air bags are made by Japanese supplier Takata.

The government opened an investigation this month after getting six reports of air bags rupturing. It estimates 1.1 million vehicles in the U.S. could be affected.

The recalls are limited to states and territories that have hot, humid weather for long periods of time. The government says data suggests vehicles in those areas are most at risk.
