Hyundai Motor said Thursday the ongoing truckers' strike is affecting production at its main domestic plants, which are already suffering from a global chip shortage.

About 6,500 out of 22,000 members of the Cargo Truckers Solidarity began a strike Tuesday, demanding the government extend a freight rate system meant to guarantee their basic wages amid soaring diesel prices.

Striking cargo truckers refused to deliver automotive parts to Hyundai's five plants in Ulsan from 2 p.m. Wednesday, causing a disruption of vehicle output due to a lack of auto components.

Hyundai produces about 6,000 vehicles of 17 different types a day at its five plants in Ulsan, an industrial city located about 410 kilometers southeast of Seoul. The models include the Genesis GV80 SUV and the Hyundai IONIQ 5 all-electric model.
