Toyota recalls 70K vehicles to replace airbag inflators

DETROIT — Toyota is recalling about 70,000 Toyota and Lexus brand vehicles in North America to replace airbag inflators that could explode. The recall covers the 2003 to 2005 Corolla, 2002 to 2005 Sequoia, 2003 to 2005 Tundra and 2002 to 2005 Lexus SC. Takata uses the chemical ammonium nitrate to create a small explosion and inflate the bags. But it can deteriorate and burn too fast, blowing apart a metal canister. About 65,000 of the recalled vehicles are in the U.S.
