The applicants in class actions over alleged engine defects in Hyundai and Kia vehicles can file amended cases, over the objections of the car makers, which claim the new pleadings are "worse" despite millions of dollars having been spent on discovery.

Three years after filing, the class actions against Hyundai and Kia are trying to pinpoint the defect at the heart of the cases, with the car manufacturers complaining that the newest pleading, which seeks to expand the claims to include an additional 380,000 vehicles, is still missing key details.
