Transmission & drivetrain
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.
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. …
Fuel & propulsion system
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. …
My Ioniq6 slowed down to 20 mph for the second time tonight. No matter how hard I pressed on the accelerator the car would not speed up past 20 mph. A message on the dashboard said "Limit: 20 mph". Eventually the car picked up speed then said "Limit: 43 mph". (The speed limit on University Blvd at this point was 35 mph). I did not test that, as I was almost home. This happened around 7pm on Saturday, Nov 18, 2023. My wife was in the car with me and asked why I was driving so slowly. The first time this happened, a couple weeks ago, I don't recall seeing a message on the dashboard. I fiddled with some of the controls on the steering wheel and it sped up. So I thought I had fixed it.
