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 2025 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: “The vehicle exhibited charging failures on multiple occasions over the course of several days after being connected to a Level 2 home charging unit overnight. On repeated mornings, the high-voltage battery was found to have not charged. The vehicle also exhibited intermittent slow charging behavior during this same period. Approximately six months prior to the charging failures, the 12-volt auxiliary battery was found to be completely discharged. During this same period, the vehicle was started on one occasion to find that every warning and alarm indicator on the dashboard had triggered simultaneously. The vehicle was completely inoperable at that time. After several minutes, all warning indicators cleared and normal operation resumed without any intervention. The vehicle was brought to an authorized Hyundai dealership on March 6, 2026, where the technician diagnosed the root cause as a failed Integrated Charging Control Unit (ICCU). The ICCU is responsible for managing both high-voltage battery charging and maintaining the 12-volt auxiliary battery; a failure of this component can result in loss of charging capability, auxiliary battery drain, and potentially a complete and sudden loss of vehicle operability. As of the date of this report, the vehicle is awaiting parts with an estimated repair time of approximately one week. The repair is expected to be covered under the manufacturer’s warranty. This failure occurred with fewer than 10,000 miles on a 2025 model year vehicle. Based on publicly available owner reports and online forums, ICCU failures appear to be a recurring issue across multiple Hyundai IONIQ model variants.” (NHTSA Complaint #11723686)

Power Train,Electrical 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 2025 Hyundai IONIQ 5 include infotainment malfunctions, battery drain, warning lights, power window failures, and intermittent starting problems. 32 NHTSA complaints have been filed for this category. Owner reports include: “I started driving and pulled out of a parking lot onto a busy road. The ICCU had failed unknownst to me and as I was underway the car started losing power and the dashboard lit up with warnings about the electrical system. I was limited to 25 MPH for a brief time and struggled to turn off into a parking lot amongst much faster traffic. While doing this the car slowed further to 10 MPH. I limped at this speed into the parking lot at which point it turned off and lot all power. This happened over the course of about 30 seconds. If it had happened on a busier road I would have been in trouble. On the highway and it would have been extremely dangerous. It was dangerous enough as is with cars passing me 20+ MPH faster than my car could go. This all occurred with no warning, and is due to an issue with the ICCU in the car that Hyundai has known about for years and has refused to address or fix.” (NHTSA Complaint #11725135)

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 2025 Hyundai IONIQ 5 include infotainment malfunctions, battery drain, warning lights, power window failures, and intermittent starting problems. 26 NHTSA complaints have been filed for this category. Owner reports include: “While traveling at highway speeds, the vehicle suffered a catastrophic and sudden loss of motive power. This resulted in a dangerous situation with no immediate ability to maintain speed in traffic. The manufacturer (Hyundai) identified a failure in the Integrated Charging Control Unit (ICCU). Despite a formal ‘Notice to Cure,’ the manufacturer refused to replace the 12V battery which was stressed during the failure, potentially leading to a repeat high-speed power loss event. This is a known issue with the E-GMP platform (Ioniq 5) that poses a significant unreasonable risk to public safety.” (NHTSA Complaint #11724193)

Active NHTSA Recalls — 2025 Hyundai IONIQ 5

The following 8 recalls have been issued for the 2025 Hyundai IONIQ 5 by the NHTSA or Hyundai. If your vehicle is affected, the manufacturer is required to provide a free remedy. Check your VIN at NHTSA.gov/recalls.

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 2025 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 2025 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 2025 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.

2025 Hyundai IONIQ 5 Lemon Law Questions

How many repair attempts qualify my 2025 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 2025 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.
