Honda recalls 2.4 million older cars to replace Takata air bag inflators

Honda is recalling 2.4 million older vehicles in the U.S. to replace potentially dangerous Takata airbag inflators.

Other versions of Takata inflators used ammonium nitrate to cause a small explosion and inflate airbags. But the chemical can deteriorate when exposed to high temperatures and humidity and blow apart a metal canister, hurling shrapnel. At least 25 people have been killed and hundreds injured.
