Hyundai Ioniq 5 Lemon Law

The Integrated Charging Control Unit (ICCU) manages DC fast charging and AC charging and keeps the 12-volt battery charged. On the Ioniq 5, the ICCU can fail from overvoltage at the start and end of the 12V charging cycle and from thermal loading during charging or driving.

When it fails, the car typically shows a "Power Limited" warning on the instrument cluster, then gradually loses power until it can no longer move — often stranding the driver and requiring a tow. Some owners report the vehicle won't charge or start at all.

Hyundai recalled 2022–2024 Ioniq 5 vehicles (part of NHTSA recall 24V204) to inspect and, if necessary, replace the ICCU and its fuse and update the software. Hyundai has issued more than one campaign in this family, adding VINs as failure data came in. But owners have reported the problem recurring after repair and long waits for backordered parts — which is exactly where California's Lemon Law comes in.

Hyundai issued 24V204 in March 2024 with a software update as the remedy, then expanded the campaign as 24V868 in November 2024 because that first remedy proved insufficient. That sequence is worth understanding, because it does work you would otherwise have to do yourself: the manufacturer has stated in its own federal filings that its initial repair for this defect did not resolve it. If your Ioniq 5 was "fixed" under the first campaign and failed again, you are not an unlucky outlier — you are inside a pattern Hyundai has already documented.

The ICCU is the headline, but it is not the only reason Ioniq 5 owners call us. The other recurring complaints are a 12-volt accessory battery that goes flat on its own and leaves the car dead in a driveway, a charge port door that will not unlatch or freezes shut, DC fast-charging sessions that throttle to a crawl or drop out partway, the head unit rebooting or going black along with the 360-degree camera and Bluelink connectivity, power liftgate and door handle failures, heat-pump and cabin-heat problems, inconsistent regenerative braking and a soft or unpredictable brake pedal, and "Check Electric Vehicle System" messages with no clear cause. Any one of these can support a claim on its own if the dealer cannot fix it.

Software matters here in a way it does not on a gas car. Much of what the Ioniq 5 does is controlled by code, and dealers often respond to a complaint with an update rather than a part. That still counts. If your Ioniq 5 has been through several updates aimed at the same fault and the fault keeps returning, that is a repair history worth documenting, not a series of non-events.

Time limits are tighter on a Hyundai than on most brands. Hyundai opted into California's AB 1755 framework, which means a claim generally has to be filed within one year of your express warranty expiring, and in no event more than six years from the date the vehicle was originally delivered. That outer six-year limit is hard, and it does not care how long the dealer kept telling you a fix was coming. If your Ioniq 5 is an early one, do not sit on it. 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 actually looks like: Hyundai refunds your down payment, the monthly payments you have made, sales tax, license, registration, and finance charges, and pays off the loan or lease. It subtracts a mileage offset for the use you got before your first repair visit for the defect — miles at that first visit, divided by 120,000, multiplied by the purchase price. You can also recover incidental costs like towing and rental, which add up fast on a car that strands you. If the refusal to repurchase was willful, California allows a civil penalty of up to two times 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 5 has been out of service for 30 or more cumulative days.

If your Hyundai Ioniq 5 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.
