Hyundai, Kia & Genesis ICCU Lawsuit, Were You Affected? Second Class Action Filed Over Twice-Recalled Charging Defect

If your Hyundai, Kia, or Genesis EV has lost power, drained its 12-volt battery, or left you stranded — even after a recall repair — you’re not imagining it. A new class action, filed September 23, 2026, in the U.S. District Court for the Western District of Washington, claims the automakers’ two rounds of ICCU recalls never actually fixed the defect. Here’s what the lawsuit claims, and what it means for you.

Who Is Hyundai, Kia, and Genesis and Why Are They Being Sued Over the ICCU?

Hyundai, Kia, and Genesis are commonly owned brands that share the same E-GMP electric vehicle platform — and with it, the same Integrated Charging Control Unit. The ICCU is the part that converts power from the high-voltage battery into the 12-volt electricity that starts the car, runs parts of the braking system, and keeps basic accessories alive. Plaintiffs argue the automakers knew the ICCU could fail from voltage and thermal stress years before recalling it, and that when they finally did recall it, they replaced a defective part with another version of the same defective part.

What Did Hyundai and Kia Do Between 2022 and 2026?

The lawsuit alleges Hyundai and Kia knew about ICCU failures well before either recall. According to the complaint, Hyundai had identified heat damage inside returned ICCU units by October 2022, and confirmed 618 unique failure incidents in the U.S. between March 2022 and March 2024 — before the first recall was even announced. NHTSA’s own recall report for campaign 24V-868 confirms the defect: an internal transistor can fail and blow the ICCU’s fuse, cutting off the 12-volt battery’s charge.

Hyundai and Genesis issued a first recall in March 2024, then a second recall in November 2024 that explicitly replaced the first — meaning owners who’d already had their car “fixed” once were called back to the dealer for a second repair. A related lawsuit already covers the same defect in New Jersey federal court, filed in April 2026 by two owners who say their post-recall problems never actually stopped.

Here’s the number that reframes this one: in a September 2023 joint test with NHTSA, one of the automakers’ own vehicles stalled completely after just 21 to 26 minutes of driving under harsh conditions. That’s not a rare edge case — that’s a demonstration the company itself was part of.

Who Is Covered by the Hyundai, Kia & Genesis ICCU Lawsuit?

Here’s exactly how to know if this case includes you. The lawsuit covers specific model years across three brands:

• 2022-2024 Hyundai Ioniq 5 and 2023-2025 Hyundai Ioniq 6 and Ioniq 9
• 2022-2024 Kia EV6 and 2024 Kia EV9
• 2023-2025 Genesis GV60 and GV70 Electrified
• 2023-2024 Genesis GV80 and GV80 Electrified
• Vehicles outside these exact model years, even from the same brands, are not covered by this specific complaint

Owners Outside Washington State — Are You Still Covered?

Yes. This is a nationwide product defect class action, not a state consumer-protection claim — it doesn’t matter where you live or bought the vehicle, only whether your specific model and model year is on the list above. The case was filed in Washington because that’s where the filing attorneys, Hagens Berman, are headquartered, not because coverage is limited to that state.

That’s worth knowing because these cases sometimes get confused with state-specific privacy or lemon-law claims — this one isn’t that.

Not sure if you qualify for the Hyundai, Kia & Genesis ICCU lawsuit? A free consultation with a product liability attorney can help you sort out whether your specific VIN and repair history fits the claim.

What Are Hyundai and Kia ICCU Owners Asking the Court to Award?

No money yet. No claim form yet. The complaint seeks to recover owners’ and lessees’ financial losses — overpayment at purchase or lease, repair costs, rental car and towing expenses, gas costs from being stranded, and loss of use while vehicles sat at dealerships awaiting backordered parts. Plaintiffs are also asking the court to order Hyundai and Kia to provide a repair that actually fixes the defect, not just another copy of the failing part.

What Could Hyundai and Kia ICCU Owners Receive If This Settles?

Impossible to predict right now — the case was just filed. For scale, Hagens Berman previously secured settlement relief valued at up to $1.3 billion for Hyundai and Kia owners over a separate defect, the Theta II engine litigation — but that took years and involved a far larger number of affected vehicles. Talk to a product liability attorney if you want to understand your options rather than wait and see.

What Should Hyundai, Kia & Genesis ICCU Owners Do Right Now?

1. Most owners don’t need to do anything yet — no class has been certified, so there’s no form to submit.
2. Save every dealer repair order, including ones marked “no fault found” or listing only a software update.
3. Write down every date your 12-volt battery died, your car entered limp mode, or a dashboard warning appeared — things like “check electric vehicle system” or “stop vehicle check power supply.”
4. Keep records of rental cars, towing bills, and loaner vehicle periods tied to ICCU repairs.
5. Confirm whether your vehicle already went through both the March 2024 and November 2024 recalls — if symptoms returned after either repair, that’s central to this case.
6. Monitor this new Washington case alongside the existing Young v. Hyundai Kefico case in New Jersey federal court, since either could move toward a class settlement first.

Hyundai, Kia & Genesis ICCU Lawsuit — Frequently Asked Questions

Is there a class action lawsuit against Hyundai and Kia for ICCU failures right now?

 Yes — two, in fact. A new case was filed September 23, 2026, in the U.S. District Court for the Western District of Washington, in addition to Young v. Hyundai Kefico, Inc., which has been pending in the District of New Jersey since April 2026.

Do I need to do anything right now to be part of the ICCU lawsuit? 

No. No class has been certified in either case, so there’s nothing to sign up for yet. If your vehicle matches the affected model years, hold onto your repair records.

When will the Hyundai and Kia ICCU case settle?

 There’s no timeline. The Washington case was just filed, and the New Jersey case remains in early litigation. Hagens Berman’s own prior case against these automakers, over the Theta II engine defect, took years to reach its $1.3 billion settlement.

Can I file my own lawsuit against Hyundai or Kia instead of joining the class?

 Yes, individual claims — including under state lemon laws or the federal Magnuson-Moss Warranty Act — remain an option. A product liability attorney can help you weigh that against waiting on the class action.

How will I find out if the ICCU lawsuit settles? 

Court filings are public through each case’s federal docket. AllAboutLawyer.com will update this page and the related New Jersey case article as both develop.

What does it mean that Hyundai and Kia “twice recalled” the ICCU? 

Hyundai and Genesis issued a recall in March 2024 (campaign 24V-204), then a second recall in November 2024 (campaign 24V-868) that explicitly replaced the first — meaning the same vehicles were called back to dealers twice for the same underlying problem. Kia’s recalls followed the same pattern under campaign numbers 24V-200 and 24V-867.

What specific harm does this lawsuit allege?

 That a defective ICCU can drain the 12-volt battery, trigger warning lights, and cause partial or total loss of drive power — including while the vehicle is being driven — and that Hyundai and Kia knew about the defect before either recall.

How much could Hyundai and Kia ICCU owners get if this case settles?

 Too early to say. The complaint seeks reimbursement for out-of-pocket costs and diminished vehicle value, plus an order requiring an effective repair, but no dollar figure has been proposed at this stage.
