I have owned the car for less than 2 years and it has had 2 ICCU units put in it under warranty. I'm worried about the viability of the car after the warranty runs out. I would hope that given the problems with this component that Hyundai will help customers with this known problem.

On October 16th our ICCU blew. I know Hyundai says this only affects 1% of vehicles, but the 2 people we also know with the same car have had the same failure, so this seems impossible so I wanted to report it. - The ICCU broke and fuse blew while charging. It blew while charging at 24 amps and actually blew the adjacent breaker as well in our panel. - The ICCU and main fuse were confirmed to be blown by the dealer in October. - There were no symptoms or warning lights most of the time; it just blew our panel breaker and would no longer AC charge. While trying to charge it, it did briefly show an electrical vehicle system error code, but when we turned it off and back on it went away. - My understanding is that with a blown fuse and ICCU it does not charge the 12v battery, so while we could drive the car and not even realize there was a problem, the battery could die while driving and create a very unsafe situation.

While charging at a level 2 charger (6 kW) the car stop charging at 61% for no apparent reason. I was unable to restart charging. Within 2-3 minutes of starting the car and driving, received a warning to “check the vehicle electrical system” and then within another minute or two, another warning to “stop vehicle and check power supply.” I was traveling under 20 mph the entire time.

STEERING
Shift gear was not engaging then i noticed the knob was slightly sticking out so I pushed it back in. The car changed gear then but it happened again a couple days later but this time the knob fell off while i was trying to push it back in. Brought to the dealers for inspection in September within a week after the problem started. Followed up twice now with no update as to when it will be fixed, I was told they will need to order part and that the entire shift gear will need to be replaced. They didn’t seem to be concerned about the safety of driving the vehicle around meantime. My husband used my car for a long trip while i was out of the country and he said the shift gear fell again. If it gets loose the gear does not engage.

Was charging the car at home in my garage when the charging session stopped. Opened the door and smelled electrical burning. Was able to put the car in neutral and push it out onto my driveway, fearing that an electrical fire could be disastrous. Called Hyundai roadside assistance and they had it towed to the closest dealership that can work on EV's (35 miles away). No report yet, but I'm pretty sure it's an ICCU failure.

The car stopped both Level 1 and 2 charging. But Level 3 charging worked. When it stopped in the middle of Level 2 charging, it tripped my circuit and bricked my Juicebix Level 2 charger. Hyundai replaced the ICCU.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated that the vehicle was repaired under NHTSA Campaign Number: 24V868000 (Electrical System); however, the repair failed to prevent a failure from occurring shortly afterwards. The contact stated that while driving at 55 MPH, the vehicle was rattling abnormally. The vehicle was taken back to the same local dealer where it was diagnosed, and determined that all four tires needed to be replaced. The four tires were replaced. In addition, the contact stated that while driving at 35 MPH, the instrument panel abnormally illuminated. The vehicle was towed to the local dealer where the vehicle was originally purchased. The vehicle was later towed back to the same local dealer and diagnosed with a leak that contaminated the rear inverter. The vehicle was not repaired due to the costs and the warranty being invalid. The manufacturer was made aware of the failure. The failure mileage was approximately 132,000.

I plugged the car into our Juicebox charger and waited for the car to say “charging scheduled” before I walked away. My husband didn’t realize I plugged in and managed to back out of the garage, ripping the charger from the car. We need to buy a new charger now. We understand the car should never move if the charger is connected.

I have had all recall updates on the car including a recent one on 10/13/2025. Turned on the heater on the first cold night in Dallas this fall and got the engine warning light. Checked the ODB and code was P1A90(96). I was able to drive it to the dealer with a 40 mph max speed. The funny thing is my ICCU has already been replaced under warranty once like 16 months ago, so it seems the replacement parts aren't much better than the original. Dealer confirmed it is an ICCU failure and I'm now waiting on the part. Hyundai has NOT fixed this ICCU problem even when they replace with a new ICCU. Someone needs to hold them accountable for finding a real fix.

On November 29 2025 my 2022 Hyundai Ioniq 5 with 49000 miles was warming up in the driveway. I heard a pop sound from the back seat like a soda can being opened (or a fuse blowing). Immediately afterwards warning lights appeared on the dash saying "Check Electrical System." The vehicle lost power to accelerate and could not be driven effectively. After a few moments, another error saying "Power is Limited" appeared. This could have happened on the roadway which would have been hazardous to myself and other drivers. The car is scheduled to be diagnosed next week by Simmons Rockwell Hyundai in Elmira, NY. These symptoms are similar to the hundreds of other reports of ICCU failures in this car and similar models. On Sept 10, 2025 the car was previously issued software updates to the ICCU software , which were required under NHTSA Recall Number 24V868000. If this problem is proven to be an ICCU failure, the experience with this car is an example of the 2025 software update failing to prevent the ICCU Failure. I request swift action from the NHTSA to compel Hyundai to implement a permanent fix for my vehicle and all other afflicted models in order to make Americas roadways safe again. Until then, everyone should be extra careful when driving behind a Hyundai Ioniq, 5 because it is at risk of dying and coming to a complete stop at any moment. Hyundai is a large corporation and has the resources and technology to fix this, but they have not done so, despite there being more than 300 complaints to the NHTSA about these cars at the time of this writing.

Electric Drive System Inoperable, sustained an immediate failure upon engaging in Drive mode. Dashboard lit up with warning lights and messages. Luckily was just pulling out onto road when vehicle completely died. Tow service unable to start vehicle with jumper module. After being towed to dealer, was diagnosed with failed ICCU. The original ICCU was replaced previously in January 2025. Luckily was not underway on the road when it happened. There was no warning, no indication that there was any problem.

The ICCU (Integrated Charge Control Unit) failed. The car was in a Hyundai dealer repair shop on November 18, 2025, for an unrelated regular maintenance procedure when (i) the technician noticed a logged ICCU error code generated sometime prior to the shop visit and (ii) after the technician cleared that prior error a second new ICCU error code was generated. The shop replaced the defective ICCU. This car had been serviced on prior occasions to install updated ICCU software, most recently as part of NHTSA's recall 24V868000 of November 18, 2024 (also known as Hyundai Safety Recall 272), intended to eliminate such ICCU failures. Installation of that software as the remedy for recall 24V868000 clearly did not prevent the very ICCU failure it was intended to guard against. Please note also that it is common knowledge (as disseminated on various Ioniq 5 forums and Reddit groups) that large numbers of later Ioniq 5 vehicles with newer VINs not included in recall 24V868000, i.e., from model year 2025 onward, have also suffered from these failures despite being initially placed into service with the updated ICCU software, as well as many other pre-2025 remedied vehicles. The Hyundai ICCU software currently in operation on both remedied cars from recall 24V868000 as well as newer cars not subject to that recall is clearly entirely ineffective as a solution to this very serious safety issue. I strongly urge NHTSA to (i) declare the existing ICCU software to be an ineffective remedy for recall 24V868000, (ii) include all Hyundai Ioniq 5 cars for all model years, whether running current ICCU software or not, to be part of the group of unremedied and unsafe vehicles, and (iii) extend recall 24V868000 until such time as Hyundai can actually demonstrate that an effective remedy exists and is being made available to all Ioniq 5 vehicles.

The Integrated Charging Control Unit (ICCU) failed - the car is no longer capable of driving due to the lack of ability to charge the battery. I was able to get it to the repair center. The ICCU on this model can fail in multiple ways, which includes the vehicle becoming inoperable at highway speeds. The issue first started 2025/11/13. I tried multiple charging units. It flipped the breaker on my home charger and caused issues for a public charger.

Even after the recall service performed, the ICCU still failed 10 months later. DTC P1E011C is listed and will not charge. This is the same issue for the KIA EV9 and a TSB needs to be issued the same as the TSB 339 KIA did for the EV9.

The car would not charge. The Dealership where the car was bought assessed the problem and found out that the Integrated Charging Control Unit (ICCU) of the car had failed. They already replaced the component, however I am reporting this problem so as to be included in the statistics for this common problem with this Hyundai make.
