Owner report 11561700 · 2023-12-24 (December 24, 2023)
My Ioniq 6 Limited AWD experienced a phantom braking event in a covered parking lot with no cars or pedestrians anywhere near the front of my car. The car just stopped suddenly with a warning message "Emergency Braking", and it wouldn't allow me to proceed until I turned off the car and then turned it back on. Fortunately, there wasn't a car close behind me at the time, but it could have triggered a rear end collision. Prior to this phantom braking incident, but on the same short drive, I noticed that the car incorrectly showed a red line in…

Owner report 11555846 · 2023-11-18 (November 18, 2023)
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…

Owner report 11742125 · 2026-06-04 (June 4, 2026)
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 warnin…
