Ford Motor Co agreed to recall more 2004 and 2005 Ranger small pickup trucks after the crash in Malaysia because their air bags are similar to the one that caused the woman's death, the National Highway Traffic Safety Administration said on Friday.

More than 12 million vehicles have been recalled worldwide because of a potentially deadly problem with air bag inflators made by Japanese auto parts supplier Takata Corp. At least five deaths and multiple injuries have been linked to the problem, which occurs when air bags inflate with too much force and blow apart metal canisters, sending shrapnel into the passenger compartment.

After the July 27 crash, which killed a pregnant Malaysian woman and her unborn baby, NHTSA began looking into air bag inflators made at a now-closed Takata factory in LaGrange, Georgia, south of Atlanta. Takata told the agency the plant made the single-stage inflator that went into the woman's 2003 Honda City small car. It was not used in any US vehicles, according to a NHTSA memo released on Friday.

But Takata said some Rangers got a similar inflator. In discussions with NHTSA, Ford agreed to recall the pickups to replace the driver's air bags. Complicating matters, many of the same pickups already were under recall for the passenger air bags made by Takata. The Rangers are the only US vehicle with inflators similar to those used by Honda in its City model, the agency said.

It was unclear how many Rangers are covered by the additional recall, but NHTSA said about 25,000 still are in use in the US. A Ford spokeswoman said yesterday night she was not aware of any air bag incidents involving Rangers.

The pickups are among 26,000 vehicles that Ford added to its list of recalls for the air bag problem, bringing its total to about 85,000.

NHTSA said it is investigating Takata air bags that are more than a decade old, regardless of where they were manufactured. The company also has air bag plants in Mexico and Washington state.

In addition to the NHTSA investigation, Takata is being probed by the US Attorney's Office in Manhattan and a federal grand jury in New York. Company executives are also scheduled to appear before a Senate committee on Thursday.

All of the recalled Ford vehicles are in high-humidity areas of Florida, Hawaii, Puerto Rico or the US Virgin Islands. Takata has said airborne moisture can cause the air bag propellant, ammonium nitrate, to burn too fast, shattering the metal canisters.
