2023 HYUNDAI IONIQ 5 Complaints

12V battery died and vehicle not operable. Luckily vehicle was parked. This has recurred multiple times (3+) Issue has been confirmed by dealer. Not addressed yet. No warning lights of imminent problem

ICCU failed post software update. Driving home and was suddenly alerted electrical vehicle systems were malfunctioning, and shortly following (1 or 2 minutes), the car flashed a new warning telling me to stop the vehicle. Had I been on a busy highway or a one lane street with low visibility, it would have put me and my wife in danger of being struck by other traffic. Luckily, I was very close to home so I drove home and did not drive the car for a few days. while researching what to do, I had read about the ICCU failure and my problems were similar. I called a tow truck to get it out to a dealer. When attempting to shift the card into drive or reverse, the car would not move. Dealer has determined that my ICCU is in fact bad and is currently in the shop being replaced. Unknown how long this will take.

both the 12v battery and the ICCU failed while driving. The dashboard light gave us 1 minute to pull over before the battery system died and the car stopped fully dead. Needing towing to dealership service.

Car bounce if at 62 MPH had dealership check balance and rear two tires could not balance. Dealership de-rimmed tires and found the inner foam has fallen or detached from the inside of tire causing. Resulting in foam moving around inside tire throwing g off balance.

Sound deadening foam inside the tire delaminates and causes SEVERE wheel imbalance. This is a widespread issue on all the Hyundai Ioniq 5 forums with this tire. Mine cost me $300 and countless hours to diagnose. IT also severely impacted the cars handling and prevented the car from driving over 46mph (in my case), which is extremely dangerous on interstates. My local tire shop balanced the tires with the maximum allowed amount of weights, but then the vibration was still there at 59mph. The Hyundai dealer then diagnosed it and they charged me $180 to do a dynamic balance. According to their results, the tires were "bad" and needed to be replaced. I went to Costco to replace the tires at a cost of

My Hyundai IONIQ5 suddenly lost power while I was driving it. I was only able to go 20 mph for a short period of time before it completely died. I had to have it towed

The vehicle was towed to the dealer; however, the vehicle had not been diagnosed. The dealer was made aware of the failure but confirmed that parts were not yet available.

I bought my Ioniq 5 in April 2023, starting in June 2023 I started having issues with the internal navigation system locating my vehicle on a different route than I was actually on. When I connect to Apple CarPlay to be able to use Google Maps or Waze, it also throws my cell phone system off and will be taken into wrong streets. Vehicle navigation also detected me driving in the wrong direction alerting me not to enter the street. I took video and photos to the dealer starting in June 2023 for a few months. They first updated the software which took over 6 hours, and my car spent the night at the dealer. Unfortunately it did not resolve the problem, they then replaced the antennae also not resolved issue. They replaced the camera in front of the rear view mirror, also no resolution. Lastly they replaced the head unit under warranty. My car continues to have the same issues with navigation and recently while on the freeway and the navigation and Apple CarPlay were acting up, when i switched lanes it alerted me of a collision and car began to break while driving 65 miles per hour. This could have caused me to be rear ended if there would have been a vehicle behind me. I do not feel safe driving this vehicle which i depend on the navigation maps for my daily work. Currently i am avoiding driving on freeways to ensure the car does not suddenly brake and cause me to be rear ended. I contacted the dealer and they stated they have not detected the same issue on other Ioniq 5's sold at Puente Hills Hyundai in California. In researching through the internet, i found there are others experiencing the same issue. Dealer asked me to bring my car in once again, but i am not sure what they can do. Hyundai needs to figure out the issue on the Ioniq 5 navigation system and issue a recall to fix the safety glitch with the system.

I was driving 45 miles per hour on a 2 lane highway, when the car suddenly started beeping, lurched, and dropped to 25 miles per hour (low power mode). After pulling over at a gas station, I was able to run the car in this low power mode for a short time, and then the 12V battery completely died. The main battery in the car was at 78%. There was no warning light that this would happen before making that drive. I took the car in to the dealer and they informed me that the ICCU failed. I see that there is an investigation underway for the 2022 Ioniq 5, and that the 2023 Ioniq 5 has the same components. Please take this investigation seriously as if I were going on a faster highway or more cars were around, it could have resulted in a major accident. This car has just over 10,000 miles and was just purchased under a year prior at the time.
