Nine carmakers operating in South Korea will voluntarily recall 478,371 vehicles to fix faulty components, says the Ministry of Land, Infrastructure, and Transport.
The vehicles belong to 171 models.
The nine companies include Mercedes-Benz Korea, Honda Motor Co., Audi-Volkswagen Korea, Kia Corp., and Hyundai Motor Co.
Among the problems was the Mercedes-Benz E 300 4MATIC sedan's faulty emergency communication system, Hyundai Tucson and Kia Stinger's faulty hydraulic electro control unit, Honda Accord's faulty drive shaft system.
The companies have either begun providing or will offer repair and replacement services.
According to the ministry, vehicle owners can have the parts replaced at designated repair and service centers free of charge.
