(CNN) A federal agency is expanding an investigation into potentially defective air bags in more than 12 million vehicles produced over the past decade. The National Highway Traffic Safety Administration says it's looking into air-bag control units installed in vehicles produced by Chrysler, Honda, Hyundai, Kia, Mitsubishi and Toyota. Air-bag control units sense when a collision is imminent and deploy the bags to protect motorists. The NHTSA said last week it hasn't identified any electrical issues in Kia and Hyundai vehicles that weren't part of those recalls. ZF, maker of the air-bag control units, said in a statement that the company "is committed to motor vehicle safety."
