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.

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 car suddenly cut speed to 20mph while traveling at around 40mph. No matter how hard I pressed on the accelerator, it did not go over over 20mph. The dashboard also said speed limited to 20mph. I had to pull over on the side of the road. Turn off the ignition. Then turned it back on. Then the car resumed to operate as normal. Luckily there were no other cars around so I could safely pull over. This could had been disastrous if it cuts speed again when I-€™m driving at 65mph on a busy freeway. I feel unsafe operating this vehicle because I-€™m afraid this will happen again in the near future.

The car randomly stops charging when plugged into either of my Level 2 home Juicebox 40 chargers before it reaches capacity, generally after adding another 4-8% to the battery. It was impossible for me to fully charge the car without plugging it in multiple times. The service people including the EV specialist said they hadn-€™t heard of this problem, and it was probably due to my charging unit at home. See the attached service and repair invoice. This was not true It is apparently a well-known defect in the Hyundai and Genesis cars using this platform and Hyundai is aware of the issue. it is not a problem with my charger. It happens whether it is hot or cold and generally when it is cooler as we only charge the car at night. Please note the following: 1.Saying this was a unique isolated problem was NOT accurate as this is a problem with many Hyundai and Genesis cars on this battery/charging platform. The Hyundai forums are full of these accounts, and they occur with all different types of chargers. For instance, see: a.https://www.youtube.com/watch"v=_3eh0BTSdng b.https://www.reddit.com/r/Ioniq5/comments/wrilke/ioniq_5_stops_charging_randomly_on_level_2_any/ c.https://www.ioniqforum.com/threads/charging-issues.42357/ d.https://www.kiaevforums.com/threads/charging-problem-automatically-stops-charging-at-home-the-charging-for-ev6-failed-please-check-vehicle.3659/page-12 3.The Ioniq 5 charges fine on level 3 superchargers 4.I spoke to Juicebox and they said other Ioniq 5 owners have reported the same problem in fact before I even mentioned the car I had, when I mentioned the problems, the technical advisor said, -€œDo you have an Ioniq 5"-€ He showed me downloaded graphs that show that the Ioniq 5 halts charges prior to being fully charged even though the charger is delivering power to the car. 5. I called Hyundai and they said they would look into this, but other people have received the same response, but nothing has been done
