Hyundai class action lawsuit overview:
- Who: Plaintiffs Hayes Young and Roy A. Williams filed a class action lawsuit against Hyundai Kefico Inc.
- Why: Young and Williams claim Hyundai Kefico failed to disclose that its integrated charging control units (ICCU) have a defect that can cause them to fail.
- Where: The Hyundai class action lawsuit was filed in New Jersey federal court.
A new class action lawsuit alleges Hyundai failed to disclose that its integrated charging control units have a defect that can cause them to fail, resulting in a loss of power and an increased risk of a crash.
Plaintiffs Hayes Young and Roy A. Williams claim Hyundai failed to disclose the ICCU defect to consumers, resulting in them purchasing vehicles that are worth “substantially less” than what they paid for them.
Young and Williams want to represent a nationwide class and two state sub-classes of consumers who purchased or leased a Hyundai, Genesis or Kia EV6 vehicle that contained a defective ICCU.
“The defective ICCUs are prone to fail which results in or is caused by an open ICCU fuse which results in an inability to charge the 12-volt battery after which motive power will fail as the battery drains,” the Hyundai class action lawsuit says.
Class action claims Kia EV6 and other vehicles can lose power
Young and Williams argue the ICCU defect can cause the battery’s state-of-charge to deplete rapidly, resulting in a loss of power and an increased risk of a crash.
The plaintiffs claim Hyundai’s ICCU design combines on-board charging with vehicle control and DC converter functionalities, which, they argue, increases the risk of power loss in the event of a failure.
Other electric vehicles, meanwhile, have separate components for these functions, allowing for cheaper repairs and reducing the risk of power loss, according to the Hyundai class action lawsuit.
“Hyundai has heretofore refused to replace the ICCU probably due to the fact that defendant only produces defective ICCUs,” the Hyundai class action alleges.
Young and Williams claim Hyundai is guilty of unjust enrichment and violating the consumer protection laws of New Jersey and Kentucky, among other things, and are demanding a jury trial, declaratory and injunctive relief and an award of compensatory damages for themselves and all class members.
Last year, Kia was hit with a lawsuit claiming the company knowingly sold 2021–2023 Soul and Seltos vehicles with a defect that can result in engine failure and potential fire.
