Hyundai Motor Co., South Korea's largest car producer, plans to appeal a U.S. court verdict ordering it to pay $248 million in punitive damages for a 2011 accident, local news reports said Wednesday. The parents of Missoula's Tanner and Trevor Olson filed a lawsuit against Hyundai for the crash of a Hyundai car that killed the teenagers aboard. They claimed the 2005 Hyundai Tiburon lost control due to a steering defect, leading it to collide head-on with a vehicle driving in the opposite lane on July 2, 2011.
