Owners of more than 300,000 Hondas have yet to get their airbags repaired, despite warnings from the automaker and regulators that the inflators have an extremely high chance of rupturing and causing injury or even death. Last week authorities said one of those air bags, equipped with an inflator made by Takata Corp., ruptured and killed a California woman, adding urgency to the search for the noncompliant vehicles.
