Owners of Hyundai Ioniq 5, Ioniq 6, Kia EV6 and Genesis electric vehicles may be covered by a proposed class action alleging Hyundai Motor America sold EVs with a twice-recalled Integrated Charging Control Unit (ICCU) linked to drained 12-volt batteries and loss of drive power. No class has been certified and there is nothing to file yet.

This article describes a class action complaint. The statements below are unproven allegations. Hyundai Motor America has not been found liable, there is no certified class, and nothing to claim at this time. This page is informational and is not legal advice.
What Is the Hyundai ICCU Lawsuit?
A proposed class action filed on September 23, 2026 targets the Integrated Charging Control Unit, or ICCU, used in Hyundai Motor Group’s electric vehicles. The case is Goldenkranz v. Hyundai Motor America, No. 2:26-cv-03581, in the U.S. District Court for the Western District of Washington in Seattle.The suit was brought by Hagens Berman, which describes it as a case on behalf of Hyundai, Kia and Genesis EV owners over an ICCU that has been recalled twice and that, according to the firm, is linked to drained 12-volt batteries and loss of vehicle power.
The complaint itself is not publicly available yet, and OpenClassActions has not been able to review it. That leaves several basic points unconfirmed: exactly which legal claims are pleaded, how the proposed class is defined, and whether Kia America or Genesis entities are named as defendants alongside Hyundai Motor America, the only defendant listed on the court docket. The docket so far shows the complaint, an issued summons, a notice of appearance and an application for an out-of-state attorney to appear.

What the ICCU Does and What Owners Report
The ICCU sits between the high-voltage traction battery and the rest of the car. Among other jobs, it keeps the conventional 12-volt battery charged, and that 12-volt battery runs the systems a car needs to start and operate.NHTSA’s recall summaries describe the failure this way: the ICCU may become damaged and stop charging the 12-volt battery, which can result in a loss of drive power, and a loss of drive power increases the risk of a crash. The new lawsuit, as the plaintiffs’ firm describes it, centers on those same two symptoms — 12-volt batteries that drain and vehicles that lose power — and on the fact that the part has now been recalled twice.
Those are the plaintiffs’ allegations. Hyundai has not responded in court yet, and no court has found that the ICCU is defective or that any recall remedy was inadequate.
Which Vehicles Were Recalled for the ICCU
The recall history below comes from NHTSA’s records, not from the lawsuit. The complaint’s own list of vehicles, and whether it goes beyond these recalls, could not be confirmed.- Hyundai recall 24V-204 (reported March 15, 2024) covered certain 2022–2024 Ioniq 5, 2023–2024 Ioniq 6, Genesis GV60, Genesis GV70 Electrified and Genesis G80 Electrified vehicles.
- Hyundai recall 24V-868 (reported November 18, 2024) expanded and replaced it, covering certain 2022–2024 Ioniq 5, 2023–2025 Ioniq 6, Genesis GV60, Genesis GV70 Electrified and Genesis G80 Electrified vehicles. Hyundai’s campaign number is 272 and Genesis’s is 025G.
- Kia recall 24V-200 (reported March 14, 2024) covered certain 2022–2024 EV6 vehicles.
- Kia recall 24V-867 (reported November 18, 2024) expanded and replaced it for certain 2022–2024 EV6 vehicles. Kia’s campaign number is SC327.
NHTSA’s recall records for the Kia EV9 do not include an ICCU campaign. A separate Kia recall reported in July 2026, 26V-431, covers high-voltage battery cells in some 2022–2024 EV6 and 2024 EV9 vehicles; that is a different part and a different problem from the ICCU.
Recalls are issued by vehicle identification number, so not every car of a listed model and year is included. A VIN search on NHTSA’s recall lookup shows whether a specific vehicle has an open recall.
What the Recall Remedy Is
Under both current campaigns, NHTSA’s summaries say dealers will inspect and replace the ICCU and its fuse as necessary and will update the ICCU software, at no charge. Owner letters for the second round went out in December 2024.The second recalls say vehicles already repaired under the first round will need the new remedy as well. An owner whose car was fixed in 2024 should not assume the recall is closed on that vehicle; a fresh VIN check shows whether the newer remedy is still outstanding.
An Earlier ICCU Case in New Jersey
This is not the first ICCU case. Young v. Hyundai Kefico, Inc., No. 3:26-cv-04198, was filed on April 21, 2026 in the U.S. District Court for the District of New Jersey and is assigned to Judge Michael A. Shipp. Carscoops reported it in April 2026 as a lawsuit over the ICCU and its recall. The complaint there is not publicly available either and has not been reviewed. The docket shows the court has twice extended the defendant’s deadline to respond, most recently on September 10, 2026. No class has been certified in that case.What Owners Can Do Now
There is nothing to sign up for or file. If the case survives early motions and a class is later certified, or if it settles, class members would normally get notice with instructions at that point.In the meantime, owners of the recalled models may want to hold on to paperwork that shows what happened to their vehicle:
- dealer repair orders for any ICCU replacement, fuse replacement or software update
- recall completion paperwork showing which remedy was performed and when
- towing, roadside assistance and rental or alternate transportation records
- receipts for 12-volt battery replacements or jump-start service
- purchase or lease documents showing the VIN and dates of ownership
Other Hyundai and Kia owners may also want to check the $62.1 million Hyundai and Kia airbag control unit settlement, which is taking claims, and the separate Hyundai Palisade airbag defect lawsuit.
What Happens Next
Hyundai Motor America has been served with a summons and will have a set time to answer or move to dismiss. Early defenses in vehicle-defect cases often include motions to dismiss and, where purchase or lease contracts contain arbitration clauses, motions to compel arbitration. A settlement or class certification, if either happens, is typically a year or more away.This page will be updated when the complaint becomes available or the case moves.
Questions
Can I get money from the Hyundai ICCU lawsuit?
Not at this point. The case was filed on September 23, 2026 and is at the complaint stage. No class has been certified, there is no settlement, and there is no claim form. Hyundai has not been found liable for anything.
Which vehicles were recalled for the ICCU?
According to NHTSA, Hyundai recall 24V-868 covers certain 2022–2024 Ioniq 5, 2023–2025 Ioniq 6, Genesis GV60, Genesis GV70 Electrified and Genesis G80 Electrified vehicles, and Kia recall 24V-867 covers certain 2022–2024 EV6 vehicles. Each replaced an earlier ICCU recall from March 2024. A vehicle identification number search on NHTSA’s recall site shows whether a specific car is included.
What is the ICCU recall fix?
NHTSA’s recall summaries say dealers will inspect and, as necessary, replace the ICCU and its fuse, and will update the ICCU software, free of charge. Vehicles repaired under the first recall in 2024 need the newer remedy as well.
Does the lawsuit name Kia and Genesis as defendants?
That could not be confirmed. The court docket lists the case as Goldenkranz v. Hyundai Motor America, and the complaint itself was not publicly available for review. The plaintiffs’ law firm describes the suit as brought by Hyundai, Kia and Genesis EV owners.
What records should ICCU owners keep?
Owners who have had an ICCU failure or recall repair may want to keep dealer repair orders, recall completion paperwork, towing and roadside assistance records, rental or alternate transportation receipts, and 12-volt battery replacement invoices. None of that is needed to file anything today, because there is nothing to file.
