NHTSA Complaint #11570778 — 2023 HYUNDAI IONIQ 5

12/30/2023 at approximately 5:30pm I drove home with the iPedal engaged. The iPedal was installed as a download to the car in August 2023. My daughter was in the passenger seat. I began to back into my driveway but shifted to Drive to straighten out the car. The car began to roll forward I took my foot off the accelerator but the car did not stop in spite of the iPedal being engaged. I put my foot on the BRAKE PEDAL which went all the way to the floor to no avail. The car rolled slowly into an electrical pole which brought the car to a stop. Neither iPedal nor the foot brake pedal had any effect on the car. I then put the car in reverse and backed the car into my driveway and the brakes worked as expected. When I then attempted to charge the vehicle, the charging port would not open. I could hear the motor working to open but it would not open. On 1/11/2024, I again attempted to open the charging port and this time it did open. So, TWO different electrical (including the brakes and the charging port) were not working properly. Inasmuch as the charging port again worked and the brakes again worked, there clearly was a malfunction that was random and unpredictable and also nearly impossible to reproduce but if this happened once, it could happen again. The brakes failed. Had we been traveling on a busy road, or at the top of a hill, we would have faced significant bodily harm, death to ourselves or others. This car had been driven locally, predominantly on local roads. The car is available for inspection and has only been driven on the dealer lot since the the incident. There were no warning lights or messages to indicate that any issues existed. The manufacturer has executed an inspected but has not reproduced the problem. The manufacturer and dealership claims the car is safe to drive without addressing the brake failure. I do not believe the car is safe to drive without a determination of how the bake failure happened or without a repair to that issue.
