POWER TRAIN, VEHICLE SPEED CONTROL, STEERING
When driving for a distance at higher speeds, power will suddenly drop to the zero point btw acceleration and regeneration. You can feel the car start to drag as the power drops. If you press hard on the accelerator to stop it from slowing, it will suddenly jump forward. This has happened now on several long trips where I am constatly fighting with the car to keep it powered and not slipping into the zero zone. When it leaps forward the lane assist will also grab control and make it difficult to control the car. The car also stops slowing consistently when I take my foot off the accelerator and will move/ jump forward more than is typical for an EV instead of slowing the way an EV should as it regenerates. This all happened twice previously on a long trip and today constantly during a three hour drive. Does not feel safe!

I was driving on the highway passing an 18 wheeler when suddenly the car decelerated and stop quick and was unresponsive and screen showed electric system malfunctioning. Could not moved from left lane on the highway. Thanks God that the person behind me at the moment was a police officer who helped me stop the traffic so we could move the the car to the service road. Car is on the shop and they are trying to figure out what is going on

ELECTRICAL SYSTEM, POWER TRAIN, EXTERIOR LIGHTING
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. After the basic fuse replacement, it caused the problem to become worse, and revealed an ICCU problem, that then revealed acceleration and charging problems, and the initial fuse problem still persisted. Codes kept popping up, and whenever they fixed the current issue, another one would present. Long story short, it turned out the vehicle was experiencing “mass power surges,” issues with the batteries, and displaying codes for reasons they were unsure of, causing the basic fuse replacement to “pop.” They even called in a Hyundai Engineer directly from corporate to try to fix the vehicle, but according to Evan, even he had no idea what was wrong with the vehicle and had left with some data.

Got a check electrical system warning and moments later the message to stop the car. Was able to pull into a parking lot where the car lost all power and had to be towed to dealer. Just received word that I have an ICCU failure and the part is on back order.

ELECTRICAL SYSTEM
The ICCU (integrated charging control unit) failed while I was out. I had to get the car towed to a dealership and it's been sitting in their lot for over two months. It took them two weeks to even confirm the issue, and the part is on indefinite backorder at the time of writing this. When the ICCU fails, the car cannot recharge the 12V battery. This forces the car to not travel above 25 MPH and when the 12V battery finally dies, the car will not be able to start. There was no prior indicators that would suggest such a critical component was about to fail, and apparently is such a common occurrence that there is a waitlist for the replacement. My ETA has been pushed back 3 times so far.

Charging port overheats while charging causing it to stop charging. Charging port is hot to the touch. Seems like a fire hazard. This issue has gotten worse over the last few weeks.

ELECTRICAL SYSTEM
On 3/22/23, after using my car most of the day, I started my car to leave work and heard a small pop noise and a warning appeared on my dashboard to 'Check Power Supply'. As I was relocating to another parking spot, the car gave an audible beeping warning and another warning appeared on my dashboard to 'Stop Vehicle Immediately and Check Power Supply'. After speaking with the dealership, it was determined that my car had to be towed. I did not experience any loss of power/speed because I was only in a parking lot. The dealership informed me the next day that the car needed a new fuse and ICCU, but that the part was on backorder and they did not have an estimate on when they may get the part in. Repairs to my vehicle were completed on 5/3/23 (6 weeks) later. Hyundai did agree to reimburse me for the cost of a rental vehicle, but did not reimburse me for the gas expenses that were incurred that I otherwise would not have had.

The charge port in the car overhears when on a Level 2 (240v) charger running above 30 amps. This is happening to most 2022 Ioniq 5 cars, not just mine. Hyundai is aware and they just made it harder to charge over 30 amps. This is incredibly dangerous! They need to recall the associated parts before fires occur. It is unsafe to charge the car at the advertised rate!!

ELECTRICAL SYSTEM
My car is unable to charge at the advertised 48A charge limit due to overheating of the charge port. Once I start charging, within 30 minutes to 2 hours the car will stop charging abruptly. It appears this is due to the AC Inlet port sensor reading 212F degrees when the issue occurs. The car is advertised as having 48A charging and if it’s not capable of this, Hyundai needs to resolve it.

ELECTRICAL SYSTEM
This is an electric vehicle, stated in product literature and safety sticker at charge port that it is capable of 48A / 240V AC charging. Under normal circumstances, the charging port overheats when supplied with 48A / 240V AC. The vehicle aborts charging due to the overheating charge port when ambient temperature is above 70 degrees Fahrenheit. This is a safety risk, and the charge port needs to be designed in a way that it will not overheat when charging at levels specified in the manual and safety tags located at the charge port, regardless of normal ambient temperatures.

On Monday Jun 19 2023 around 7pm PT while I was parallel parking, I heard a pop from the engine area and immediately saw the center console show a warning message (one beep, then no further beeps): “Check electric vehicle system” I finished parking and left the car running while I starting to investigate online what this error meant. After ~2 minutes parked I got an active alarm (beep beep beep beep) that said “Stop Vehicle and Check Power”. I turned off the car. The battery was at 22% at this time, with about 44 miles of range. BlueLink Vehicle Diagnostic accessed from the in-car infotainment system said no issues found. The MyHundai App Diagnostic Report on my Android phone said All Systems Normal. On advice from a Hyundai dealer that I could drive 2 miles home, so I did. When the car started I saw the warning “Check electric vehicle system” and made it about 5 minutes before I got the active alarm “Stop vehicle and check power” I turned off the car and turned it back on and finished the 5 minute drive home. Thursday of the same week, the Android app continued to say All Systems Normal and on the same day I paid to have the car towed to a Hyundai dealer. Today, July 10th, I finally got a call back from the Hyundai dealer that the ICCU (Integrated Charging Control Unit) was in need of repair and that they have no ETA for when the part will come available. I do appreciate that they offered me a loaner car during the wait, however long that will be. I saw on the NHTSA website that there was an active investigation into a similar issue, and wanted to share my story.

Made an attempt to start the vehicle and noticed two messages on the dash as follows 1. "12V battery Voltage Battery Low" 2. "Stop Vehicle and Check Power Supply" Attempted to put the vehicle in drive. The vehicle would not engage in drive mode. Shut the vehicle off and made a second attempt to restart the vehicle. This time the vehicle did not start. Had the vehicle towed to a local Hyundai dealer. Hyundai dealer took 2 weeks to diagnose the problem. Was advised by the dealer that the ICCU module needed to be replaced along with fuses, and coolant. Also noticed vehicle having slow acceleration at times after charging. Also notice a weird noise on right rear passenger side of the vehicle sounding like fluid pumping at times. Vehicle has been at the dealer for 27 days and still not repaired

ELECTRICAL SYSTEM
I have an Emporia charger connected to a 60AMP breaker that can charge at a constant 48amps. This was installed as per the codes by a certified electrician. I have been owning this car since October 2022 and has over 14k miles on the car. Till last week, the car charged at 48amps without any issue. But since yesterday, charging starts smoothly till 1-2 hours. Then every 6-7 minutes, charging stops for some seconds and starts back up. After several cycles of stop and start charging, the entire charging ends before reaching the set limit. 2 weeks ago, the dealership updated the VCU as per the latest June TSB Hyundai released.
