DETROIT - U.S. safety regulators have added about 320,000 older-model Honda Odyssey minivans to a widening probe of faulty air bags that affects at least three automakers and more than 2 million vehicles.
Front air bags on the Honda Motor Co. minivans from the 2003 and 2004 model years can inflate without a crash, possibly injuring drivers and passengers.
The National Highway Traffic Safety Administration says in documents posted Monday on its website that the vans have the same air bag control computers that already have caused Toyota Motor Corp. and Chrysler Group LLC to recall more than 1.8 million vehicles worldwide.
The air bag control computers were made by auto parts supplier TRW Automotive Inc.
So far, the agency has received six complaints about the Odyssey air bags inflating without crashes. In three cases people reported injuries. The NHTSA also received 41 complaints of air-bag warning lights illuminating.
The agency will determine if the problem is widespread enough to recall the minivans.
In one of the complaints about the Odyssey, a driver in Hattiesburg, Miss., told NHTSA the air bags went off suddenly in May 2012 while a 2003 Odyssey was parked and the driver had an iPad on the steering wheel. The air bags threw the iPad into the female driver's face. She ended up at a hospital emergency room, and a plastic surgeon had to be called in to stitch a cut in her upper lip. Some of the driver's teeth were chipped, and she needed dental work, the complaint said.
The owner paid $2,331 to fix the air bags, according to the complaint.
Honda said in a Dec. 21, 2012, letter to NHTSA that the rate of related problems with Honda vehicles is extremely low. Honda said in the letter that it would continue to handle front air bag incidents on a case-by-case basis.
The automaker said in a statement that it's been monitoring the situation and will cooperate with NHTSA. It's too early in the investigation to draw conclusions about the whole population of older Odysseys, the company said.
