My understanding is that these illegals were working on the construction of a new Hyundai plant - not working in an operating automobile manufacturing plant. So, the onus might be more on the construction company than Hyundai, itself. However, I did find it interesting that a few of the arrested illegals were reportedly South Korean nationals - and Hyundai is a South Korean company.
