Federal regulators and U.S. prosecutors in New York City have reportedly opened their own investigation into whether Kia and Hyundai properly handled recalls here in the U.S. amid hundreds of unexplained vehicle fires, which the I-Team first reported on last April. Last month, Kia and Hyundai recalled more than 170,000 vehicles for fire hazard defects. A Hyundai spokesman told the I-Team in an email, "As a company policy, we are not able to confirm, deny or otherwise comment on the reported visits by the Korean authority."
