American transport authorities have recalled more than 2 million Toyota, Chrysler and Honda vehicles for a second time over faulty airbags that may inadvertently inflate while the car is running. The U.S. National Highway Traffic Safety Administration said Saturday the recall was issued following the unexpected deployment of airbags in about 40 cars that had already been fixed under a previous recall.

All 2.12 million vehicles involved in the latest warning were already under recall for an airbag default. About 1 million Toyota and Honda vehicles in the latest warning are also subject to related recalls involving Takata airbags, which may unexpectedly inflate and cause serious injury or death. The exploding Takata airbags are linked to at least five deaths and hundreds of injuries.
