TOKYO, Japan (CNN) - Toyota will employ new quality control officers, conduct testing and will consult an independent research agency to fix their vehicle problems, the automaker's president said Wednesday.

But Toyota President Akio Toyoda said he will not appear before U.S. lawmakers at hearings scheduled for later this month.

Toyoda addressed reporters for the third time in two weeks about the massive recall.

Toyota has recalled more than 8.1 million vehicles worldwide for problems related to sudden acceleration and unresponsive brake pedals, among other things. The company has apologized for the safety lapses and pledged to repair the recalled vehicles quickly.

On Wednesday, Toyoda said the company has found a fix for the Toyota Sai, sold in the U.S. as the Lexus HS 250h, and began notifying owners about recall procedures.

"Toyota is not perfect. But when we find a problem or are made aware of it, we act as quickly as possible. We are sincerely working on that," Toyoda said. FULL STORY
