South Korea's top automaker Hyundai Motor Co. said Tuesday it is voluntarily recalling 515 vehicles in the United States due to a defect in the airbag system.

According to Hyundai, Tucson sport-utility vehicles produced in South Korea from Nov. 10 and 30 last year and exported to the U.S. will be subject to the recall.

The move comes as the company found a defect in the airbag system in the front passenger seat, which may not properly work in a crash, the company said.

The recall came less than a week after Hyundai decided to recall about 47,000 units of its new Sonata sedan in the U.S. and South Korea, citing a glitch in the front-door locks.
