A larger, more recent investigation. Appears that this is still going on despite Hyundai denials? A very long article..but worth reading if the subject interests you--one take-away is that the issue appears to be the staffing agencies habit of sending young teens to work :
A Reuters investigation found child workers throughout Hyundai and Kia's supply chain in Alabama. State and federal authorities are probing their suppliers.

The employment of children at Hwashin and Ajin hasn’t been previously reported. The news follows a Reuters report in July that revealed the use of child workers, one as young as 12, by SMART Alabama LLC, a Hyundai subsidiary in the south Alabama town of Luverne. In August, the U.S. Department of Labor said that SL Alabama LLC, another Hyundai supplier and a unit of South Korea’s SL Corp, employed underage workers, including a 13-year-old, at its factory in Alexander City.
Since then, as many as 10 Alabama plants that supply parts to Hyundai or Kia have been investigated for child labor by various state and federal law enforcement or regulatory agencies, according to two people familiar with the probes. The investigations are being conducted across small towns and rural outposts where many of the suppliers and the job recruiters that staff them are located. It isn’t yet clear whether the probes will lead to criminal charges, fines or other penalties, the two people said.
On Aug. 22 a team of Labor Department and Alabama state inspectors arrived unannounced at one of Ajin’s plants, according to people familiar with the operation. As the team arrived, workers rushed out the back and left the premises before they could be questioned, one of the inspectors told a meeting of Alabama’s anti-human trafficking task force last month, according to two people who attended. The inspection hasn’t previously been reported.
