ICCU failure. Total and sudden loss of power. No acceleration. "Limp mode" activated for 5 miles before total shut down.

ICCU failure, code P1A9096.

On March 19, 2026, at approximately 1003 hours, I was traveling north on the [XXX] located in [XXX] . I was traveling in the number two lane and my speed was approximately 78 MPH when all of a sudden I had a loss acceleration power and my Kia EV9 began to decelerate rapidly and my dashboard began to flash a loss of power warning. I had no control over my accelerator and could not speed up. Due to the rapid deceleration I had to take evasive action as northbound highway traffic was flowing smoothly. My clearest path was to move to the lefthand shoulder, which required me to cross the number one lane and the carpool lane. During this time, my Kia EV9 continued to decelerate. Once I got my vehicle onto the shoulder I placed my vehicle in park at which time my dashboard highlighted the front storage compartment of my vehicle in red. I assumed that meant my frunk was open. I exited my vehicle and checked my frunk and indeed found that my frunk was open and the first stage of the two-stage latch system was disengaged. Had the second stage of the latch system been disengaged it could have resulted in catastrophic consequences due to me traveling at highway speeds on a multilane highway. To be clear, I did not touch the interior compartment frunk release button and my keys were sitting in my left cargo short pocket located on the side of my left leg. I had also been traveling for approximately five to seven minutes and had entered the highway via the northbound [XXX] . I came to a stop at approximately the [XXX] area, which is approximately two miles north of [XXX] . I am aware that electric model Kia vehicles have a safety measure in which if the frunk or trunk is open the vehicle computer system does not allow the vehicle to engage in drive or reverse mode. Since I do have an electric vehicle, a diagnostic of my vehicle computer could reveal the cause. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The first time I drove on a highway in this brand new car the windshield chipped. There are facebook group posts of other drivers experiencing numerous chips and cracks in the windshield. I'm not sure how this compares with other cars, but I've been driving for about 20 years and have had little rocks/pebbles hit the car windshield and never have had an issue with a chip in the windshield. I'm not sure how unsafe this is-- if the entire thing could break-- the dealership I go to is patching it for me-- but this may be a consumer issue and possibly a safety issue too.

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
