I was driving down the freeway driving at the speed of traffic. My vehicle started beeping aggressively, a red indicator started flashing over the frunk area of the vehicle representation in the dash and my vehicle entered red turtle mode. This red turtle mode severely reduced the vehicle's speed and ability to maneuver on the freeway. I was almost struck by numerous vehicles while attempting to get to the side of the road. I had been driving in the number 3 lane of a 5 lane freeway where lane 1 was an exit only offramp. Once I got to the side of the road, I power cycled the vehicle. when that didn't revolve the red turtle issue. I pressed the frunk open button. I heard the opening mechanism actuate. I then reseated the frunk latch and closed the frunk. Once the vehicle was turned back on, all issues were resolved and the vehicle behaved as normal.

Car was driving find and suddenly check electric system message came in with a red battery indicator. The application for the car indicates an ICCU P1A9096 error code. ICCU errors seems to be common with Kia/Hyundai electric cars. Car went to limp mode and wouldn’t let drive it more than 45mph which it was dangerous in the highway. I was able to get the car into the dealer but the last mile the car was very limited in power with no more than 30mph. Radio, A/C and other accessories stop working

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2026 Kia Ev9 verdict →
