Suddenly whilst driving, I heard a soft "pop" and emergency alert sound and message were displayed. Car lost almost all power, but was able to move forward at 12mph to park in a safe place. Car became fully inoperable and required a flatbed tow to dealership. Was diagnosed as an ICCU problem (associated with both 12v battery failure and possible bluetooth related battery drain). Car has been in shop for 6 weeks, waiting on parts. No ETA from Hyundai. If this had occurred 3 minutes later I would have been driving at high speed on the interstate in morning commute traffic. Prior to the "pop" there was no warnings or errors or problems - car worked perfectly.

We've owned the car since new, just over one year. The car was performing well one day and my wife went to her evening work. When she returned to her car around 6pm, the car wouldn't respond to the key fob and the door wouldn't open. She was able to open it with a key, but the car wouldn't start. It's a fully electric car and NOTHING lit up or made a sound. The traction battery had ample charge, but she called Hyundai and the car needed a "jump" from a repair vehicle that was called out, much like an ICE car needs the occasional jump...we assumed an interior light was left on, but the car's app didn't inform either of us of any issue prior to this...the same exact scenario repeated itself about one week later and we had the car jumped again and brought to our dealer, Burns Hyundai in Marlton, NJ. They determined that "nothing was wrong" which made no sense to me. My wife picked up the car and approximately one week later, the exact same thing happened again. This time we dropped the car off at the dealer where it's been for nearly one month. With their customer service lacking and information not forthcoming, I had to go to the dealer myself to get some answers. It seems the computer was telling then some codes were coming through about the battery, but nothing more. It didn't need replacing and they couldn't replicate the problem over a period of weeks...There are MANY online reports of this car having 12V battery and ICCU issues. Our dealer has several Ioniq5s awaiting ICCU replacement for the same problem as my car, but they "can't get the part from Hyundai". While our car at times won't start, they aren't seeing that in their shop now, awaiting repairs on cars that apparently die when driving also with 12v battery problems. Our car is a lemon and we intend to retain counsel to assist us in its repair. https://www.theautopian.com/why-everyones-favorite-electric-car-keeps-stranding-its-owners/?fbclid=IwAR3yNgwVKtaGhGPd7HBz79tOV-UI1myLdmyrwDzcOJZfLarsG80b_6NJLpk

The contact owns a 2023 Hyundai Ioniq 5. The contact stated that the vehicle failed to charge at 120 or 240 volts. The charging unsuccessful alert was displayed. The contact stated that the vehicle only charged on a DC fast charger. The vehicle was taken to the dealer where it was diagnosed that the ICCU (Integrated Charging Control Unit) that allowed both high-voltage and secondary batteries in vehicles to be charged had failed. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 500.

- #11517184April 15, 2023UNKNOWN OR OTHER, VISIBILITY:WINDSHIELD
Windshields in the vehicle keep breaking with little to no reason. In 6 months of ownership we have fully replaced 3 windshields. Windshields provide a line of protection for the driver and passengers when the vehicle is being operated. Continuous breaking of a windshield indicates a bigger safety issue with the manufacturing of the car/glass. In one instance there was an audible screeching sound and the glass suddenly cracked for no reason. The windshield has been replaced and safety system recalibrated 2 times in 7 thousand miles ownership with the 3 appointment scheduled for completion in a week.

Pulled out of my driveway and halfway down the street, warning message pops up on display, "Check electric vehicle system". Turned down another street to head back home and receive another warning with audible beeping "Stop vehicle and check power supply". Dealership says its a known issue and to not drive it. Must be safety related or driving it wouldn't be a problem.

On March/17/2023 @24962 miles Integrated Charge Control Unit failure + 30 AMP Fuse. Hyundai Corporate said parts back order May---June/2023 time frame. 3 inch orange circle came up on my dash with red triangle saying PULL OVER IMMEDIATELY! I was two blocks from dealership and with no problems drive to the service advisor where it died in front of them. Service advisor guessed that the pop I heard just before the circle appeared was the fuse and I drove in on the 12volt battery. I am in the Buy Back process with Hyundai Corporate Case#21170992

The car was driving fine, and an error popped up indicating to pull over and check battery. As I am going to pull over a red flashing indicator pops up saying “pull over and check battery”. As I start to pull over the car speed drops to 25 miles per hour and fully dies as I make it to the side of the road.

The 12v battery died because the electric battery drained it. Ultimately, the electric battery is dead on a 1 year old car and needs replacement. The night before the failure, the car had 145 miles and drained the battery to 83 miles. Prior to that and an ongoing complaint to the dealership from November until this point, the range went from 245 miles per charge to 190 to 219 miles per charge. The 219 was after a system update in January.

Hi! My vehicle went under a recall repair last month. Once completed, the acceleration significantly decreased in the ECO drive train mode. The other modes are working as before. I have been advised that this recall service was required by the NTSB. There are reports of this occurring on credible websites as well. I did report it to Hyundai, they didn't believe me. So, I am reporting this to you. Please fix my car!

After a few minutes of driving, the vehicle presented a warning "Check Electric Vehicle System" and then got really slow. We were able to limp back home, where it is now parked. Hyundai has not had availability to diagnose the issue.

When driving on the interstate the collision avoidance system will falsely trigger around 5% of the times going under overpasses or road signs. The vehicle rapidly decelerates using regenerative braking.

Was in the middle of driving when a loud alert sounded and the dashboard showed the error "Stop vehicle and check power supply". The car otherwise behaved normally. I pulled into a parking log, looked at the only thing I knew how to look at (12v battery), confirmed it was still plugged in, and turned the car back on. The error was still there, but now the car wouldn't go over 26mph. I limped home, called a tow truck to take it to the nearest Hyundai that services electric vehicles, and they told me they'd have to replace the ICCU, which is backordered.

I was driving to my parents house when suddenly a message popped up on my driver screen saying that the electrical system has a problem. Driving a little more to reach my parents house and it starts saying to stop and check power supply. We ended up making it to my parents house and decided that it was unsafe to drive anymore with the error message going off. I called a tow truck to tow it back to our dealership in Fremont. When the tow came, I thought we could drive it on the bed but turns out the vehicle wouldn't start. We jumped the 12V battery and found that we could put it in neutral and somewhat drive it until it drained the external battery used to jump the 12V battery. With the car stuck halfway on the bed, we managed to put it in neutral and pull the car up using the tow's harness. Took it to the dealer and after a few days they said a fuse blew and that something called the ICCU was bad and needed to be replaced.

- #11511276March 10, 2023SERVICE BRAKES, ELECTRICAL SYSTEM, EXTERIOR LIGHTING
When using i-Pedal (one-pedal driving) mode in this vehicle, it can decelerate at a very fast rate but does not illuminate the brake lights unless the driver’s foot is completely off the pedal. For example, I can be driving 60mph and decelerate to ~2mph as quickly as other drivers coming to a complete stop, but my brake lights will not illuminate until my foot is **completely** removed from the pedal. This is contradictory to the way one-pedal driving works, since coming to a smooth and slow stop requires that you slowly lift off the accelerator pedal, during which the brake lights do not illuminate because your foot is still pressing the pedal (albeit less and less as you come closer to the stop).

Car is 13 months old, 13,xxx miles. Driving car at 60mph we heard a bang from the rear of the car and lost power almost immediately. Car displayed warning "Check Electrical Vehicle System." We shut it off, then restarted in limp home mode, warning now said "Stop Vehicle and Check Power Supply." We then turned off the heater and the car got to 55MPH and I could get the 5 miles back to home. The 12 volt batter no longer charges, the car will not accept a Level 2 charge. IT was towed to Hyundai for repairs. Research suggests that the Integrated Charge Circuit Unit (ICCU) and the accompanying 450V/40 AMP fuse are both bad.

I've owned this car for 4 months now. We own 2 electric cars, 1 ioniq 5 and 1 Fiat 500e. We have a level 2 charger in the garage. A month ago I noticed the ioniq stopped charging overnight. When I tried the next day, it charged for about 30 minutes, then I would get a msg on my phone saying charging had stopped. I can remotely start the charging again, but then it would stop every 10 or 15 minutes. This is still happening. The Fiat has no issues charging, leaving me to believe it's not the charger that is the problem. I've even reduced the charge to the middle level but it hasn't helped. I will be taking this into Hyundai this month for them to see what's wrong.
