Toyota (NYSE:TM) said Monday it has repaired more than five million vehicles involved in three US recalls announced in late 2009 and early 2010 for unwanted acceleration and brake troubles, and expanded a program intended to drive value and safety for customers.

Since the recalls, Toyota has fixed about 80% of the 2.3 million vehicles recalled for problems involving accelerators, 86% of the 148,000 cars recalled for anti-lock brake systems, and 58% of the 5.4 million recalled for floor mat entrapment.

“Toyota has made significant progress in recent months to help ensure that our customers can have complete confidence in the quality, safety and reliability of their vehicles, and our latest initiatives build on those accomplishments,” said Steve St. Angel, chief quality officer of Toyota’s North American division.

The company has expanded the scope of its on-site SMART evaluation process following a sharp drop in customer concerns regarding acceleration, which has dropped 80% since the program launched in April.

Since the program commenced, Toyota has evaluated some 4,200 vehicles, and has yet to find a case where the electronic throttle control system would lead to unintended acceleration.

Within the expanded program, all new vehicles will be equipped with advanced safety features, including smart stop technology and event data recorders, marking Toyota the only company that features brake override technology on its entire line of domestically sold vehicles.

The company said Smart Stop is already incorporated in 84% of the Toyota, Lexus and Scion models on sale in the US.

Also a part of the program, Toyota plans to meet with suppliers and more frequently test key parts.
