2022 HYUNDAI IONIQ 5 Complaints

The car gave an warnings of “Check Electric Vehicle System@ and started slowing down in the middleman of the road. I could have been easily rear ended or got into a serious injury. After googling, it seems almost all if not most of ioniq 5 are having this issue after certain mileage

The car started reporting error messages including "Stop vehicle and check power supply". It briefly went into limp mode before dying completely. Flat bed to dealer who can't begin diagnosis for at least a week. This sounds identical to the ICCU issue that many owners are experiencing.

My 12v battery died on 11/12 while my main battery still had 52% charge remaining. Had to jump the battery to get the electrical system to work. Since then several of the cars electrical systems are not working. This is a known issue online that Hyundai has responded to but the dealer is saying that they are not aware.

Car died in a Wegmans parking lot and dealer is telling me it will take 8-10 days to diagnose the problem which is known very well to the manufacturer and dealers. The ICCU has failed.

In stop and go traffic on freeway, car was moving at about 5 miles an hour but car kept moving, collision warning and automatic braking did not activate. Had to turn off car and coast to a stop. Nearly collided with vehicle in front

Every so often when I am driving on the highway, the car just looses power and I may catch a message that flashes on my display, "Emergency Braking". The event last no longer than about a second. When this phantom braking happens, so far, it has not been so severe to feel dangerous just unsettling!

The 12 volt battery keeps failing. Every time I contact Hyundai AutoNation it takes forever for them to do anything about it and they don't seem to understand

The car suddenly showed a warning on the screen asking me to park and in a few seconds went completely dead. It won't start at all. I can't even unlock the car. I had to call roadside assistance and have them tow the car to Ideal Hyundai dealership in Frederick, MD. It's been 4 days and the dealership can't diagnose the problem or won't communicate what the issue is.

I charge my vehicle using a home 48 amp charger. After about 10 months of ownership. I began to receive “charging unsuccessful”notifications after about ten of charging at the Maximum charging speed. I reduced the charging rate to Reduced and was able to charge continuously to 90% a couple times at that rate. However, I began to receive “charging unsuccessful” notifications at this rate as well and had to lower the charging rate to Minimum in order to charge continuously. I can not charge the vehicle at 48 amps and the vehicle can only charge at 5.7 kwh, rather than the expected 11.5 kwh. The vehicle has been repaired four times. I cannot take the car on long trips, or for intensive use, where I would need to quickly charge to car in order to continue using it. As this issue appears to be progressive, when will the car fail to charge at even the Minimum rate? When I am on the road at a remote charging station? When I have an emergency and need to use it?
