What is NHTSA investigating in the Hyundai Ioniq 5?
From NHTSA’s investigation summary:
On June 8, 2023, the Office of Defect Investigation (ODI) opened PE23011 to investigate allegations of loss of motor power on model year (MY) 2022 Hyundai Ioniq 5 vehicles.
Some consumers reported loss of motor power immediately after a warning lamp illumination or reduction of motive power while the vehicle was in motion.
This investigation found that the Integrated Charging Control Unit (ICCU) may be subject to various conditions such as overcurrent, overvoltage induced at the end of charging, and certain thermal loading during operation that can damage its internal components and open the ICCU fuse, resulting in an inability to charge the 12-volt battery.
The vehicle could eventually lose all motive power, increasing the risk of a crash.
In July 2023, Hyundai issued a service campaign to address certain MY 2022-2023 Ioniq 5 and MY 2023 Ioniq 6 vehicles that may have low 12V auxiliary battery charging occurrences due to an ICCU fault and may set the DTC P1A9096 "DC/DC Converter Input Voltage Sensor Fault".
On March 15, 2024, Hyundai filed Safety Recall 24V-204 for 98,878 MY 2022-2024 Hyundai Ioniq 5 vehicles and MY 2023-2024 Hyundai Ioniq 6, Genesis GV60, Genesis GV70 "Electrified" and Genesis G80 "Electrified" vehicles.
The recall remedy provides an inspection, and if necessary, a replacement of the ICCU and the associated fuse.
The ICCU software reduces the risk of overcurrent and implements voltage peak reduction at the end of EV battery charging.
The recall also includes a software update that revises the electric water pump operational threshold to reduce thermal loading during charging and driving.
In view of the recall action being taken by Hyundai, ODI is closing this Preliminary Evaluation.
The agency reserves the right to take additional action if warranted by future circumstances.

What is a preliminary evaluation?
Preliminary Evaluation is the first stage of a federal defect investigation. NHTSA reviews complaints, crash reports and manufacturer data to decide whether a safety defect may exist. It can close with no action, be upgraded to an engineering analysis, or end with a recall.
Did this investigation lead to a recall?
Yes. NHTSA lists recall 24V204000 as the result of this investigation: 2022-2024 Hyundai Ioniq 5 12-Volt Battery Recall (24V204).

What are Hyundai Ioniq 5 owners reporting to NHTSA?
NHTSA’s public database lists 1,015 owner complaints filed since 2020 for the vehicles in this investigation (all components). Complaints are unverified owner reports.
What should owners do?
- Check your VIN at nhtsa.gov/recalls for any open recall on your vehicle.
- If you have the problem NHTSA is investigating, take the vehicle to a dealer now and get a repair order, even if the dealer cannot find anything.
- Keep a log of every time the problem happens: date, mileage and what happened. Photos and videos help.
- File your own complaint at nhtsa.gov/report-a-safety-problem. Owner complaints are what start and expand investigations.
- If the problem keeps coming back, talk to a lemon law attorney.

Can a recall or defect investigation make my car a lemon in California?
Not by itself. What matters is whether a covered defect keeps coming back or keeps your vehicle at the dealer, and a federal investigation or recall is strong evidence that the problem is real.
Under California’s Song-Beverly Consumer Warranty Act, a manufacturer that cannot fix a warranty defect that substantially impairs a vehicle’s use, value or safety within a reasonable number of attempts may have to repurchase or replace it (Civ. Code 1793.2(d)). Within the first 18 months or 18,000 miles, the law presumes a reasonable number of attempts after two repairs of a defect likely to cause death or serious injury, four repairs of the same defect, or more than 30 days out of service (Civ. Code 1793.22(b)).
An owner who prevails can recover reasonable attorney fees and costs from the manufacturer (Civ. Code 1794(d)). You pay nothing, win or lose. We are paid only if you win, and the manufacturer pays our fees, including in settlements. If a case is lost, our firm covers the costs.
In our cases, a recall repair visit counts as a repair attempt, and it's strongest when the owner complained about the problem before the recall came out. A recall shows the defect is real and that enough owners reported it for the manufacturer to issue a fix.
The biggest mistake I see is waiting too long. The mileage offset starts at your first repair visit for the problem, so the sooner you take it in, the better. If the problem comes and goes, take it in when it happens. You can't go back to that date later.
If you get a recall notice, call a lemon law attorney right away. You may have taken the car in for the same problem before and forgotten, or there may be other recalls related to it.

Frequently asked questions
Does the recall fixing my car mean I have no case?
Not necessarily. Even if the recall repair fixed it, you may still have a case, and a car that's a year or more old can still qualify.
Do used cars qualify for California lemon law?
We take certified pre-owned, demo and dealer vehicles. Since the California Supreme Court's Rodriguez decision in 2024, ordinary used cars generally do not qualify.
How long does a recall lemon law case take?
Recall-related cases typically resolve in one to three months from your first call. Prior results do not guarantee a similar outcome.
What does a lemon law attorney cost?
You pay nothing, win or lose. We are paid only if you win, and the manufacturer pays our fees, including in settlements. If a case is lost, our firm covers the costs.
