TOKYO — Toyota started recalling more than 90,000 luxury Lexus and Crown vehicles today in Japan over defective engines — the latest setback for the automaker beset with quality problems.

Toyota spokesman Paul Nolasco said recalls in overseas markets will follow soon, totaling about 270,000 vehicles globally. That includes: 138,000 vehicles in the U.S., 15,000 in Europe, 10,000 in the Middle East, 6,000 in China, 4,000 in Canada, and 8,000 in other regions.

Toyota told the Japanese government it was recalling 91,903 vehicles for flaws in the valve springs, a crucial engine component, that could make the automobile stall while in motion.

The company announced the latest problems last week. Some 180,000 of the defective automobiles were sold overseas, 138,000 of them in the United States.

No accidents or injuries have been reported.
