TOKYO ( TheStreet) -- Toyota ( TM), the world's biggest automaker, will recall worldwide 270,000 vehicles, including its Lexus model, to fix faulty engines.

Toyota is recalling the cars because of flaws in valve springs that could make the vehicle stall while moving.

A Lexus general manager said contaminated materials had been used for valve springs during manufacturing, the Associated Press reports.

The recall begins Monday. It affects seven luxury Lexus sedan models and the popular Crown, another Toyota spokesman said. About 180,000 cars were sold overseas, including the United States, AP reports.

The recall is just the latest setback in quality problems at Toyota. It has recalled about 8.5 million vehicles since October because of problems such as sticky gas pedals.
