2023 Hyundai Ioniq 6 Complaints

My 2023 Ioniq 6 is not charging as it has for 3 years. When charging to 100% my app States 347 and 382 miles. It should be 361 as stated by Hyundai. What happens if I drive under 45 mph after 5 miles the miles goes down to 303. It is not working as stated. It is not holding miles properly.

The shift-by-wire system failed while the vehicle was being parked. The vehicle would not shift out of Drive; repeated attempts to engage Park resulted in Neutral only, with a "PARK malfunction. Engage parking brake when parking vehicle." warning displayed in the instrument cluster. Because this vehicle requires Park to be engaged before it can be powered off, the vehicle also could not be turned off. I was trapped with an energized vehicle that could not be secured in Park or shut down for approximately 30 minutes. A red 12-volt battery warning lamp was illuminated in the instrument cluster during the event (photo attached showing the malfunction message, Neutral gear state, and battery warning lamp). I secured the vehicle using the electronic parking brake. Safety risk: a vehicle that cannot engage Park or power off risks rollaway and leaves the driver unable to safely exit and secure the vehicle, particularly on a grade or in traffic. This is the second occurrence of a shift-to-park...

While driving on the highway, there was a complete loss of power and steering. I was able to navigate to the side of the road. The vehicle would not start on multiple occasions, and no warning lights illuminated. The vehicle was taken to the dealer, where it was stated that the issue could not be duplicated. The vehicle was not repaired. The manufacturer was not notified of the issue. The approximate failure mileage was 18,000.

In November of 2025 the vehicle displayed a "Check Eletrical System" error message. Shortly thereafter the vehicle decelerated to under 10mph as we were turning into traffic. We were able to drive it home (less than 1mi away) and then called the Dealership. The car was then towed to the dealer (but needed a jump as the 12v battery had drained). The dealer diagnosed a failure of the ICCU and replaced it. The vehicle was in the shop for approximately 2 weeks. More recently, on May 3rd of 2026, the vehicle experienced a complete deceleration as it was traveling through an intersection. No error lights or warning messages were displayed. I was only able to partially clear the intersection before the vehicle came to a complete stop. At this time the vehicle would not allow itself to be put into neutral so I could not push it out of the intersection. After approximately 5min of attempting to move the vehicle, it once again began responding to accelerator requests and I was able to drive i...

I was pulling into a parking spot and my vehicle suddenly lurch forward, and I had to slam on the brakes quickly, scraping the front of the curb. I checked there was no warning lights. I checked the floor mat, and this was not impeding the accelerator pedal I am certainly I did not accidentally hit the accelerator instead of the brake.
