Below are complaint narratives filed by owners of the 2023 Hyundai Ioniq 5 with the National Highway Traffic Safety Administration.
Car lost charge quickly, went into limp mode while I was driving on the highway. I had to pull of the road several times and try to get it to a charging station. It barely made it after the lose of power. Charged it to 80% and it would only go up to a range of 100 miles. Took it to the dealership and they confirmed it needed a whole new main battery. ICCU had already been replaced. Had to wait ove...
My 2023 Ioniq 5 had the ICCU replacedin 2025 and then it failed again in late January 2026. The car has been at the dealership since then awaiting a new part.
The ICCU unit malfunctioned and needed to be replaced. It occurred while I was driving home and I was lucky enough to make it to my driveway. If it had been on the freeway I would have been stuck.
2023 Hyundai Ioniq 5 displayed a "Check Vehicle Electrical System" warning on the dashboard. The Integrated Charging Control Unit(ICCU) failed, and it rendered the car inoperable. I could not drive it and was left stranded, waiting for a tow truck in below-freezing temperatures as the car completely died. Hyundai has previously recalled the vehicle for this, and my car had been serviced in the rec...
ICCU failure, left stranded for a tow
ICCU failure. Car was at 16% when I tried to charge the car. Heard a pop sound from underneath the car and the dashboard had a message saying to check the electrical system.
The ICCU failed after completing all required recalls. The car stopped working while driving. The car losing power while driving could have created an accident had I not pulled over in time. The part was replaced by Hyundai under warranty and is now fixed.
The ICCU on my Ioniq 5 failed about a year after getting the software update that supposedly addressed the issue. I am very concerned about the reliability of my car going forward as it doesn't appear Hyundai has addressed the issue and I have no reason to think the replacement ICCU component won't fail as well.
The ICCU electrical system failed for the 2 nd time owning the car. Resulting in another 2 month wait to get it repaired. The dealer says they put the same part in, that may fail again.
The vehicle is a Hyundai Ioniq 5 electric vehicle. There have been known issues with the integrated charging control unit (ICCU) failing suddenly rendering the car inoperative; I just took it to the dealer and they confirmed a fault with the ICCU. I am up to date with multiple prior ICCU recalls and updates. Leading up to this, a few months ago my 12V battery died unexpectedly at ~22000 miles and ...
My ICCU failed and left my family and I stranded. I understand that this is happening on many Ioniq 5s and that Hyundai has not come up with a reliable solution for this problem.
My 2023 Hyundai Ioniq 5 suddenly malfunctioned on Sunday, March 1, 2026. The vehicle abruptly lost power, would not accelerate beyond 25 miles per hour, and then completely died within minutes. This left me stranded on the roadside off the highway, and the car had to be towed to the dealership. It has now been over 10 days, and I have not received any updates regarding the repair timeline, or next...
Entered car on very cold day. Put heater and defroster on high, drove about a mile and then the window cracked.
12 volt battery keeps dying for normal reason. It was replaced last year. I have to jump it a few times a day. I'm afraid it will die while I'm driving. I was told at the dealer that it was because I was charging my car in the cold and the 12 volt battery will disconnect to avoid a fire. It was winter. Now we have in 80 degree temperature and the 12 volt battery is dying more frequently
I started the car and put down all 4 windows simultaneously. I heard a pop and a dash warning "Check electrical system". I knew this is symptomatic of an ICCU failure and the car will not be driveable for very far. This happened despite having recall work performed for this specific issue in September. That recall work was just a software update, but it is a hardware problem. Hyundai needs to fix ...
On [XXX], I received a warning on my 2023 IONIQ 5 that said “stop vehicle and check braking system” and the car went into “turtle mode”. I took it into the dealer for repairs and they said the issue was related to the 12V battery and returned the car to me as repaired. Then, on [XXX], I was driving the car and I got the same error message but this time the car’s brakes didn’t work. Thankfully, I w...
I received a "Stop vehicle and check power supply" alarm on my dash after starting the car and leaving a parking garage. Then a "12V battery voltage low" message along with the "turtle mode" icon which limits the car to under 20 mph. I pulled over to a side street as I did not want the car to die on a main road and impede traffic or get hit. I called roadside assistance and the car was towed to th...
I own a 2023 Hyundai Ioniq 5 that experienced a battery failure while still under warranty. The vehicle became completely undriveable in late November 2025 and had to be towed to a Hyundai dealership. The vehicle has now been sitting at the dealership for more than 90 days waiting for a replacement battery with no repair completion date provided. The dealership indicated that the required battery...

Having the same ICCU Failure that all other Ioniq 5 owners have. On February 26th, I was heading to work when I heard a pop and car displayed warning lights saying check EV system and stop safely. Car was limped home and towed to dealer. Was told fix will take a month.
