Toyota has started recalling more than 90-thousand luxury Lexus and Crown vehicles in Japan, over defective engines. It's the latest setback for the automaker beset with quality problems.

Toyota Motor Corporation says recalls in overseas markets will follow soon, totaling about 270-thousand vehicles globally. The latest quality problem comes as Toyota struggles to move on from massive global recalls that started last October.

It's already recalled more than 8 and a half million vehicles for various problems.

They included sticking gas pedals, braking software glitches and defective floor mats.
