Owner reports

Selected complaints filed with NHTSA by 2022 Hyundai Ioniq 5 owners, lightly cleaned up (personal details are redacted by NHTSA).

The contact's father owns a 2022 Hyundai Ioniq 5. The contact stated that as her father attempted to place the vehicle into reverse(R) while in park(P), the gear shifter failed to operate as needed. As her father exited the vehicle with the gear shifter in the park(P)position, the vehicle accelerated on its own into his garage. The air bags did not deploy upon impact. The contact's father was not injured and a police report was not filed. The garage door and pillar were damaged, as well as, the vehicle's driver-side door. The vehicle was initially towed to the dealer where the vehicle was inspected for the failure. The inspection found no defect with the vehicle and claimed that the failure was a result of human error. The dealer then drove the vehicle to a nearby independent collision center where the vehicle was repaired. …

1.We purchased the vehicle (Hyundai Ioniq 5, 2022 Model) on MAY 20, 2022. 2.The vehicle was acceptable until it started to fail on us while we were on the road, and soon after the vehicle crawled home at limited power and came to a stop, it would no longer even turn on. 3.Then started our nightmare with Hyundai USA. We called the service department and they told us, based on our brief description of what happened, that our vehicle would be unsafe to drive a single more mile (which was impossible anyhow because it wouldn't turn on), and to tow our vehicle to Hyundai dealership in Fayetteville, AR for repair on DECEMBER 27, 2022 at our own expense. 4. From what Hyundai, Fayetteville, AR's service engineer named Evan told us, they have replaced the fuse no less than four times and it kept blowing when they went to test the vehicle. …

I was charging my car at home like I usually do and around 2am I received an alert on my Bluelink app that a charging alarm was detected. I saw that the breaker for my charger had tripped which it had never done before. I reset the breaker and tried to restart charging but was not successful. I turned on the car and immediately got the battery and EV warning lights telling me to stop the vehicle.

The Integrated Charging Control Unit (ICCU) in my 2022 Hyundai Ioniq has not been diagnosed or repaired despite being at the dealership for 3 months for a safety recall. The ICCU controls the vehicle's electrical and charging systems, and a malfunction could prevent the vehicle from charging or operating properly, creating a risk of loss of propulsion while driving. Two different Hyundai dealers have had the vehicle since July 11, 2025, but no diagnosis or repair has been completed. I have escalated the issue to Hyundai Corporate, but there has been no resolution or communication of a timeline. The vehicle is available for inspection upon request. No warning lamps or messages were reported prior to the dealer receiving the vehicle, as the car was delivered specifically for the recall repair. …

I am submitting an update to my existing complaint regarding the ICCU safety recall on my 2022 Hyundai Ioniq 5. Since my original submission, my vehicle has been at authorized Hyundai dealerships since July 2025 and remained undiagnosed and unrepaired for over three months. During this time, I received inconsistent and misleading information from both Hyundai corporate and the dealerships regarding the status of the recall repair, as documented via emails, texts, and recorded calls. On 10/31/2025, the dealership informed me that the issue may involve a floor harness/wiring problem and it is out of warranty; however, this appears related to the ICCU safety recall, and Hyundai has not provided a firm timeline for repair. …

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. …

My 2022 Hyundai Ioniq 5 has experienced two ICCU (Integrated Charging Control Unit) failures, both completely immobilizing the vehicle. First failure: November 2024 Second failure: December 31, 2025 (confirmed by dealer 1/13/26) Downtime: Over 45 days total All recall work and maintenance were performed at the same Hyundai dealer, under active warranty, but the recall did not prevent the second failure. Safety Risk: These ICCU failures cause sudden loss of propulsion, leaving the vehicle stranded and creating a serious safety hazard. The second failure after recall indicates the repair is inadequate. Luckily mine failed at home before departing for an errand, but I am gravely concerned about others not as fortunate or for myself should the issue recur while I am traveling on a public road. Examples of this are reported online in a variety of forums. …

After a loud bang (fuse blown) the car was unable to move just before I was about to turn into an intersection. The ICCU failed for the second time, all warranty repair completed prior to the incident, first failure occurred in 2024. Both failures occurred close to a when the lead acid battery failed and needed replacement. When the car was stopped and started again, I was able to drive the car slowly to the dealership located less then 1/4 mile away. The car behaved as if there was no power steering but the car still jerked the wheel around to try to put me back into the driving lane presumably because I was driving in the emergency lane. Failed component was ICCU Module 36400-1XAA0. Vehicle was unsafe because I was unable to move while about to turn into an intersection. …

While driving, a warning message displayed on the dashboard stating that there was a fault in the electrical system and that I should pull over and stop the car. As I tried to find a safe place to pull over the car lost power and I pulled onto the shoulder. The shoulder was only as wide as the car. I was stopped on the side of a two lane road with a 55 mph speed limit. In order to exit the car I had to step into the travel lane. The electrical fault resulted in no power available to the warning flasher lights or headlights. This occurred at night with no street lighting to show oncoming drivers that there was a stopped vehicle immediately next to the traffic lane. This put me and other drivers at risk. The vehicle was towed to a dealer capable of working on this type of failure. The dealer determined that the failed component is known as the ICCU. …

This report is an addendum to report 11762283 that was made yesterday. The vehicle allows driving with the rear liftgate ajar, however under some circumstances it engages the EPB when the vehicle comes to a stop while the gear state is still Drive. The gear state of the car remains in Drive when the EPB engages. This presents the driver with the choice, in the middle of the road and possibly in the middle of an intersection, of either exiting the vehicle and rearranging contents of the vehicle to allow the rear liftgate to close, or activating the accelerator to continue driving with the traction motor overpowering clamped EPB. Neither option is safe. I have attempted to reproduce this unsafe state of the vehicle and was successful in one case and unsuccessful in another. …
