Hyundai and Kia are the dominant brands in their home country with around two thirds of the market. However, customer ire has grown due to the perception South Korean automakers are not working swiftly to address quality concerns. Hyundai's recall for the engine problem was made in South Korea only last month - one year after it recalled cars for the similar engine issue in the United States. Even before Kim's allegations came to light, customer accusations that their South Korean vehicles are priced higher and offer fewer and inferior features than those sold in the United States were widely covered by local media. Shares of Hyundai Motor ended down 1.6 percent and Kia Motors fell 1 percent. The broader market declined 0.5 percent.
