Hyundai, Kia, and Genesis Lemon Law Claims in California

Is my Ioniq 5's ICCU failure a lemon law case?

It can be, because a charging system failure that repeats after warranty repairs substantially impairs the use and value of an electric vehicle, which is what Civil Code section 1793.2(d)(2) requires. The integrated charging control unit, or ICCU, in Hyundai's E-GMP electric vehicles, including the Ioniq 5 and Ioniq 6, the Kia EV6, and the Genesis GV60 and Electrified GV70, has been the subject of NHTSA recalls after a component failure could stop the unit from charging the 12-volt battery and cause a loss of drive power.

The recall history matters to a lemon claim: an initial 2024 recall was later expanded when the first remedy proved insufficient, publicly reported class action litigation alleges that some replacement units failed too, and Hyundai extended ICCU-related warranty coverage substantially in 2026. If your EV has been in more than once for charging failures or 12-volt warnings, our deep dive on Hyundai and Kia charging system failures explains how to build the record.

What about the Theta II engine failures?

The Theta II gasoline direct injection engine, used in many 2011 to 2019 Hyundai Sonata and Santa Fe and Kia Optima, Sorento, and Sportage models, became one of the most litigated engines in the country after owners reported knocking, stalling, seizure, and fires. Hyundai and Kia resolved consolidated class litigation with a settlement valued in the billion-dollar range that included extended engine warranties and a knock detection software update. Newer engine complaints continue to appear in public complaint databases, and we track how these cases are handled in our guide to Hyundai and Kia engine defect claims.

Note what the settlement did not do: it did not buy anyone's car back under the Song-Beverly Act. Individual lemon law rights generally survive, though whether a particular owner released particular claims is a document question for attorney review.

Does an extended warranty stop my lemon law claim?

No: extended coverage gives the manufacturer more chances to repair, but it does not erase the duty to repurchase a vehicle that has already failed a reasonable number of repair attempts. This comes up constantly with these brands because Hyundai and Kia have responded to defect patterns with long warranty extensions. If your vehicle keeps failing, the extension is evidence the manufacturer knows about the problem, not a defense to a buyback. The repair-attempt benchmarks come from the Tanner presumption in Civil Code section 1793.22: within 18 months or 18,000 miles, two attempts for a defect that could cause death or serious injury, four for the same problem, or a cumulative total of more than 30 calendar days out of service. A loss of motive power on the freeway is squarely in the serious-defect category.

Have Hyundai, Kia, or Genesis opted in to AB 1755?

Yes, all three. Hyundai, Kia, and Genesis are treated as separate manufacturers, and as of July 6, 2026 the Department of Consumer Affairs' published list at dca.ca.gov shows each of them individually: Hyundai Motor America elected in on April 28, 2025, Genesis Motor America on April 28, 2025, and Kia America, Inc. on May 1, 2025. Ford, General Motors, and FCA US are also on the list, while Toyota and Honda are not. Elections bind for five years, so these run into 2030.

Manufacturers can elect in at any time, so check the current DCA list when your claim starts.

The stakes: an opted-in manufacturer gets the procedures of Code of Civil Procedure sections 871.20 through 871.30, with suit due within one year after the warranty expires and at most six years after delivery, a 30-day pre-suit notice to preserve civil penalties, and mandatory mediation. Non-opted-in manufacturers stay under the older rules, with a longer window and no notice or mediation gates. Our AB 1755 hub has the full breakdown.

What does a Hyundai or Kia buyback involve?

A repurchase typically moves through four stages: a written demand with all repair orders, the purchase contract, and a payoff quote; evaluation by the manufacturer's consumer affairs or repurchase team; a written offer itemizing the refund and the mileage offset; and a surrender appointment at a dealership where the lender is paid off, your check is issued, and the vehicle goes back. The refund must cover the down payment, monthly payments, official fees, and incidentals such as towing, rental cars, and charging equipment costs where recoverable. California law requires the reacquired vehicle's title to be branded as a lemon law buyback.

The only lawful deduction is the mileage offset under Civil Code section 1793.2(d)(2)(C). On a $44,000 EV6 first serviced for the defect at 10,800 miles, the math is 10,800 divided by 120,000, or 0.09, times $44,000: a $3,960 deduction. You can estimate your buyback with our calculator.

What pressure does the law put on a manufacturer that delays?

Two provisions do the work. Civil Code section 1794(c) authorizes a civil penalty of up to two times actual damages for a willful failure to comply, and section 1794(d) shifts a prevailing consumer's attorney fees and costs to the manufacturer. Because the opted-in procedures apply to Hyundai, Kia, and Genesis claims, the civil penalty depends on a properly sent 30-day notice, so the sequencing matters.
