Hyundai Ioniq 6 Lemon Law

The Ioniq 6's Integrated Charging Control Unit (ICCU) runs DC and AC charging and keeps the 12-volt battery charged. Like its Ioniq 5 sibling, it can fail from overvoltage during the 12-volt charging cycle and from thermal loading — leaving the 12-volt system unable to stay charged.

The result is usually a "Power Limited" warning followed by a steady loss of drive power until the sedan won't move, plus possible no-charge and no-start conditions. For a car marketed on its range and efficiency, being stranded is a serious failure of the basic promise.

Affected Ioniq 6 vehicles fall under Hyundai's ICCU recall campaign (NHTSA 24V204) for inspection and replacement of the ICCU and fuse and a software update. When the fix doesn't resolve it, the problem returns, or parts are backordered for weeks, California's Lemon Law may apply.

The campaign history matters here. Hyundai issued 24V204 in March 2024 with a software update as the remedy and expanded it as 24V868 in November 2024 after that first remedy proved insufficient. For an Ioniq 6 owner that means the repeated-attempt element of a lemon law claim may already be established by the recall record rather than by anything you need to prove — particularly if your car was addressed under the earlier campaign and the fault returned.

Plenty of Ioniq 6 claims have nothing to do with the ICCU. The recurring complaints are a 12-volt accessory battery that drains on its own and leaves the sedan dead, DC fast-charging sessions that throttle badly or drop out, charge port door latches that stick, infotainment reboots and blank screens that take the backup camera with them, Bluelink and remote-start connectivity failures, power door handle and trunk release problems, heat-pump failures that leave you without cabin heat, wind noise and water intrusion around the sloping rear glass, and real-world range that falls well short of the rating. Each of these can stand on its own if the dealer can't fix it.

Because so much of the car is software-controlled, dealers often answer a complaint with an update instead of a part. That still counts as a repair attempt. An Ioniq 6 that has been through several updates aimed at the same fault, with the fault returning each time, has a repair history worth documenting.

Hyundai opted into California's AB 1755 framework, which shortens the runway. A claim generally has to be filed within one year of your express warranty expiring, and never more than six years from the date the car was originally delivered. That six-year cap is absolute — it does not extend because a dealer kept promising a fix. These deadlines come from the Song-Beverly Consumer Warranty Act — California's Lemon Law. They are not the only route: other claims, including federal warranty claims under the Magnuson-Moss Warranty Act, can run on different timelines, so a closed Song-Beverly window does not automatically mean you are out of options. It is worth asking before you assume.

What a buyback pays: Hyundai refunds your down payment, the payments you've made, sales tax, license, registration, and finance charges, and clears the loan or lease. It deducts a mileage offset for the use you got before your first repair visit for the defect — miles at that visit, divided by 120,000, multiplied by the purchase price. Towing and rental costs are recoverable too, and a willful refusal to repurchase can carry a civil penalty of up to twice your damages.

A recall is not automatically a lemon — it's the manufacturer acknowledging a defect and offering a free repair. California's Lemon Law (the Song-Beverly Act) comes into play when a substantial defect can't be fixed after a reasonable number of attempts, or when your Ioniq 6 has been out of service for 30 or more cumulative days.

If your Hyundai Ioniq 6 qualifies, you may be entitled to a buyback (a refund of what you've paid, minus a mileage offset), a replacement vehicle, or a cash-and-keep settlement — and Hyundai pays your attorney fees on a successful claim, so pursuing your case costs you nothing out of pocket.
