I was doing a 3-point turn in the driveway, and heard a pop sound from under the rear seats. A warning light came on in the dash, after a little bit of time the warning changed into an error that stated pull the car over and do not drive. OBD sensor reported codes P1A90 and P0C17. Car also went into "turtle" mode preventing it from being driven normally. Had it towed to the dealership, but took 2 weeks for them to inspect it. Once they got to it, they quickly determined it was a blown high-voltage fuse, and a fault in the ICCU (integrated charging control unit). Was told there is a national backorder on the ICCU and no ETA on delivery. I was also told I am one of three Ioniq 5s waiting for a new ICCU. I've seen many reports online of many Ioniq 5s having this same issue, and very long wait times for ICCU replacements.

We were driving vehicle on a neighborhood street with a speed limit of 45 miles per hour. When we got a "High voltage fault warning" from the car. I continued to drive about 10 second more and got a second warning. A different series of warnings appeared the last one being "please pull over and check your electrical system". We pulled into a neighborhood street, turned off the car. We decided to try to make it home which was less than 1/2 mile. Once I restarted the car, both messages cycled through the dashboard. Then the car lost the ability to accelerate past 25 miles per hour, no matter how much I stepped on the throttle.

The contact owns a 2022 Hyundai Ioniq 5. The contact stated while driving 59 MPH, a warning message advising to stop the vehicle due to low battery was displayed; however, the main battery was fully charged. The instrument panel lights turned off and the vehicle decelerated to 23 MPH. The contact veered to the right lane. While driving to the dealer, the vehicle stalled. The vehicle was towed to the dealer, where the Integrated Charging Control Unit (ICCU) assist, and the high voltage fuse were upgraded. Additionally, the battery was replaced. The vehicle was not repaired and remained at the dealer. The manufacturer was notified of the failure and informed the contact they could not provide vehicle rental assistance because the dealer was unwilling to assist. The failure mileage was approximately 28,000.

When charging the vehicle using a level 2 charger, the charging system will often trip for unknown reasons. This can happen after 1 hour or after many hours of charging. If using specific chargers, the charging will restart after a 10 second delay and oftentimes the car will continue to trip and start recharging multiple times. This can lead to heating up of the charging cord and potentially tripping the main breaker feeding the charger. In the car you can change the charging current from maximum to reduced to minimum. The issue appears to happen mostly on maximum and reduced charge, but has not happened on minimum yet. The issue is reproducible on multiple level 2 chargers and appears to be a common issue across numerous other owners. I have attempted to have the dealership investigate, but they are too new and or ignorant to electric vehicles that they won't take my advice on how to reproduce the issue and thus have not been any help. This issue is not related to DC charging which leads me to believe it's either electrical pin related or an issue with the AC to DC converter on the car. Besides, not getting the full use of the car I paid for, this issue can leave a user stranded if the charger fails to charge the car when expected, but also could be a potential fire hazard with the excessive heating of the charging module and associated charging cords. In the attached photos you can see how often the car charging will trip as I get a notification in my phone app each time it stops charging. If you're inside the car watching the dashboard when this happens, it will flash check EV system very briefly while it trips and restarts. No actual codes are thrown though.

The car randomly drains the 12v battery. Twice it wouldn-??t turn on when I had appointments to go to. The dealership service department has had my car since 10/27/22. They-??ve replaced a bunch of parts & can-??t fix the issue. I would occasionally get battery discharge warning messages when starting the car.

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. Nearly two months after the repair, the contact stated that while in the vehicle with her father, the vehicle failed to move out of the reverse(R) position after backing out of the driveway. The contact stated the gear shifter eventually moved after multiple attempts and restarts. The dealer was notified of the failure and the contact later informed her that there was a recall on the vehicle for a shift control unit update(recall number unknown). The contact was instructed to bring the vehicle to the dealer to have the update performed. The contact notified the manufacturer about the failure and was given a case number. The vehicle was repaired. The failure mileage was 494. The contact stated that the vehicle accelerated into the door of the garage. Also, Hyundai eventually reimbursed the contact for the costs of repairs.

Following DC fast charging, I found the plastic cap (dead front) on pin #7 became dislodged and is missing. This missing component could expose the operator of the vehicle to potentially harmful electrical current when charging.

I started my car up right after charging on a rainy day at 2500 miles exactly and got 5 warnings. Check battery, lane assist warning, abs warning, parking brake warning, forward collision warning and bling spot collision avoidance warning lights were on. More or less all these systems triggered a fault. I tried turning it off and on to no luck. As I drove to the dealer my breaks became steadily lighter and lighter with the manual break even clicking at times. My breaking distance was doubled by the time that i got there. Other owners are seeing the same issue. It sounds quite similar to the Kona Electric recall (20V-748). My car is unsafe to drive.
