LOS ANGELES — Toyota Motor Corp. on Thursday named a veteran manufacturing executive to lead its North American Quality Task Force, an internal group intended to improve the quality of its vehicles after a series of large recalls and continuing controversy about unintended acceleration by the company’s autos.

Steve St. Angelo, who is executive vice president of Toyota Motor Engineering and Manufacturing North America, was named chief quality officer for North America and a member of a global quality committee.

St. Angelo’s appointment and the international committee are part of an initiative by Toyota president Akio Toyoda to address reliability and safety issues at the automaker. The committee will begin deliberations Tuesday in Japan.

In North America, St. Angelo is in charge of executing improved quality assurance; strengthened quality management training; incorporation of best practices through outside professionals; and closer cooperation with regulatory authorities.
