Owner reports include: “The ICCU has failed for the 2nd time in a year requiring lengthy repairs. The car cannot be driven with a faulty ICCU. The ICCU is responsible for converting AC power to DC for and stepping it up to 800 volts to charge the primary battery. It is also responsible for keeping the secondary 12 volt battery charged.” (NHTSA Complaint #11725450)

Electrical System,Fuel/Propulsion System

Electrical system failures are notoriously difficult to diagnose and repair, which often results in multiple unsuccessful repair attempts — a key element of a lemon law claim. Reported issues for the 2022 Hyundai IONIQ 5 include infotainment malfunctions, battery drain, warning lights, power window failures, and intermittent starting problems. 62 NHTSA complaints have been filed for this category. Owner reports include: “My 2022 Ioniq5 left me stranded late at night in a freezing rainstorm in March of 2024 when I was 75 miles from home at it failed to charge both D/C fast charging and A/C level 2 charging, despite my trying several different chargers. The car gave me the dreaded “Check E/V System” warning when it failed to charge. It turned out to be the notorious ICCU but also the AC inverter, which had to be replaced. It took 12 days. The dealership’s initial diagnosis was something draining the 12-volt battery, so I asked if they also replaced that. They said no because it had tested fine, but 9 days after I picked up the car, it did not start because it turned out the 12-volt battery was dead, and my dealership spent 2 days getting Hyundai to approve replacement of the 12-vold under warranty. Last month, 17 January 2026, my Ioniq5 again left me stranded. This time 120 miles from home in a snowstorm. It D/C charged for 10 minutes before the charging stopped and it gave me the dreaded “Check E/V System” warning. I tried two nearby Tesla Superchargers with my Hyundai issued adapter, and they both failed. I had just enough charge to make it to a dealership 110 miles from my home, where the vehicle stayed for nearly a month while they diagnosed and repaired it by replacing the AC inverter (note that had been replaced the last time) and also the AC compressor. The ICCU failures are well-known and well-documented, but the AC inverters that failed on me twice do not seem to be as common and should probably be investigated. In both cases I was stranded on Saturdays when no dealership service departments were open until the following Monday, so I had to pay for a motel overnight, which Hyundai refused to reimburse because I was not at least 150 miles from home.” (NHTSA Complaint #11719387)

Power Train,Electrical System,Fuel/Propulsion System

Electrical system failures are notoriously difficult to diagnose and repair, which often results in multiple unsuccessful repair attempts — a key element of a lemon law claim. Reported issues for the 2022 Hyundai IONIQ 5 include infotainment malfunctions, battery drain, warning lights, power window failures, and intermittent starting problems. 34 NHTSA complaints have been filed for this category. Owner reports include: “Q: What component or system failed or malfunctioned, and is it available for inspection upon request? A: ICCU failed – Not available for inspection (at least at this time, but willing to try and make it work). Q: How was your safety or the safety of others put at risk? A: The ICCU (Integrated Charging Control Unit) is a safety-critical component subject to federal recalls 24V-204 and 24V-868. (My vehicle had all recalls performed prior to this failure.) The failure occurred while driving which was indicated by a “popping” sound. It is contextually important to note that the ICCU is responsible for charging the 12v battery, had the 12v battery failed during the duration of my drive I would have experienced a sudden loss of motive power. A sudden loss of motive power is an unacceptable risk to public safety. Q: Has the problem been reproduced or confirmed by a dealer or independent service center? A: Yes, the problem has been reproduced and confirmed to be an ICCU failure by an official Hyundai service center. Q: Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? A: No. Q: Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? A: Symptoms first appeared February 14, 2026. The first symptom of failure was the signature “pop” sound that the ICCU failure is known for. Only after my drive and upon attempting L1/L2 charging did my dash warning indicate “Check Electric Vehicle System.” I also checked for codes with my OBDII scanner, and it showed no codes.” (NHTSA Complaint #11719374)

Fuel System

Fuel and propulsion system defects can cause stalling, fuel leaks, or power loss — all substantial impairments of use and safety. The 2022 Hyundai IONIQ 5 has generated 30 NHTSA complaints for this defect category. Owner reports include: “The ICCU failed while 300 miles from home. I was unable to charge the car with level 2 charging to get home. Luckily level 3 charging still worked. The ICCU breaking can also disrupt propulsion, so I’m lucky it didn’t break to that degree while driving. The dealership ultimately replaced my ICCU. There were no warning signs. In fact, the car didn’t even throw a code or error. It simply wouldn’t charge.” (NHTSA Complaint #11725470)

California Lemon Law — Song-Beverly Act

California’s Song-Beverly Consumer Warranty Act (Cal. Civ. Code §§ 1790–1795.8) is one of the strongest lemon laws in the United States. It protects buyers and lessees of new and certified pre-owned vehicles that develop substantial defects the manufacturer cannot repair after a reasonable number of attempts.

Under Cal. Civ. Code § 1793.22, a lemon law presumption is triggered when any of the following apply to your 2022 Hyundai IONIQ 5:

• 4+ repair attempts for the same non-safety defect without resolution
• 2+ repair attempts for a defect likely to cause death or serious bodily injury
• 30+ calendar days out of service for warranty repairs (cumulative, not consecutive)

Once the presumption is triggered, the burden shifts to Hyundai to prove the vehicle is not a lemon. Under Cal. Civ. Code § 1794(d), Hyundai must pay your attorney’s fees if you prevail — meaning qualified representation costs you nothing out of pocket.

What You Can Recover

If your 2022 Hyundai IONIQ 5 qualifies as a lemon under California law, Hyundai may be legally required to:

• Repurchase your vehicle — Full refund of your down payment, all monthly payments, registration fees, and incidental costs (towing, rentals), minus a mileage offset for miles driven before the first repair attempt
• Replace your vehicle — Provide a new, comparable vehicle at no cost to you
• Pay your attorney’s fees — Under § 1794(d), Hyundai pays all legal fees if you prevail
• Civil penalty up to 2x damages — If Hyundai willfully violated the Act, courts may award double the actual damages

Steps to Protect Your 2022 Hyundai IONIQ 5 Claim

Step 1: Document every repair visit. Keep all repair orders, work orders, and dealer invoices. Each visit counts as a repair attempt, even if the dealer says nothing is wrong.

Step 2: Keep returning for repairs. You must give Hyundai a reasonable opportunity to fix the defect. Visit different authorized Hyundai dealers if needed and ask for written documentation of each visit.

Step 3: Contact a California lemon law attorney. Once you believe the threshold has been met — 4 attempts for non-safety defects, 2 for safety defects, or 30 days out of service — contact an attorney for a free case evaluation. Under § 1794(d), Hyundai pays your fees if you win.

Step 4: Send a demand letter. Your attorney will send Hyundai a formal demand letter. Most California lemon law cases resolve through negotiation without going to trial.

2022 Hyundai IONIQ 5 Lemon Law Questions

How many repair attempts qualify my 2022 Hyundai IONIQ 5 as a lemon?

Under Cal. Civ. Code § 1793.22, four or more repair attempts for the same non-safety defect, or two attempts for a safety-related defect, triggers the lemon law presumption. Additionally, 30 or more cumulative days out of service qualifies regardless of the number of repair attempts.

Does Hyundai pay my attorney fees?

Yes. Under Cal. Civ. Code § 1794(d), Hyundai is required to pay your reasonable attorney’s fees and court costs if you prevail in a lemon law claim. This means qualified lemon law representation is free to you if your case succeeds.

Can I file a lemon law claim without an active recall?

Yes. A recall is not required to file a lemon law claim. The Song-Beverly Act covers any substantial defect that impairs the use, value, or safety of the vehicle that the manufacturer cannot repair after a reasonable number of attempts. NHTSA complaints support the claim by establishing a pattern, but are not a prerequisite.

What is the time limit to file a lemon law claim for my 2022 Hyundai IONIQ 5?

California lemon law claims are generally subject to a four-year statute of limitations from the date you discovered or should have discovered the defect. However, you must still be within the manufacturer’s original warranty period when the defect first appears. Contact an attorney promptly to preserve your rights.
