NHTSA Complaint #11572116 — 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. I previously filed a complaint here but I have since learned that iPedal may disengage if the car is put into reverse. There is not warning light to alert the driver that iPedal is disengaged so the driver is not aware that the brakes may not work as expected. I believe this may have been the case with my accident. However, this does not address why using the foot pedal for the brakes did not stop the car. Have found many complaints about this on various forums and believe this aspect of iPedal needs to be addressed. It should not disengage unless the driver instructs the car to do so. I have not been able to find documentation of this functionality in the manual, but I have searched and will continue to do so.
