TOKYO (AP) — Toyota executives were unfazed Thursday by the overnight recall of 7.43 million vehicles over faulty power window switches that can cause fires, calling it a sign the Japanese company had learned from its mistakes and was becoming quicker and more transparent.

They said the models affected by the biggest single recall in Toyota Motor Corp.’s 75-year history were all made before global quality controls were beefed up in 2010. The change followed a series of massive recalls, mostly in the U.S., over sticky gas pedals, faulty floor mats and defective braking.
