The head of South Korea’s second-largest automaker Kia Motors has resigned to take responsibility for mass vehicle recalls caused by defective electrical wiring, the company said Tuesday.

Chung Sung-Eun, who is also a vice chairman of the Hyundai-Kia Automotive Group, stepped down after Kia had to issue a global recall of 85,900 vehicles, spokesman Michael Choo told AFP.

The four models involved are the Soul, Sorento and Borrego sport utility vehicles, and the Cadenza sedan.
