Hyundai

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.

Car makers Tesla and Hyundai have argued NSW's law imposing a road-user charge on electric vehicles may be invalid following a High Court decision which struck down Victoria's EV tax as an invalid excise, while urging the state government not to introduce any new road charges.

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.
