NHTSA complaint: 2023 HYUNDAI IONIQ 5 — POWER TRAIN
Driver was moving forward into a space in a parking garage between two other vehicles. Driver had pulled most of the way in and was slowly inching forward. As the car came to a stop, it suddenly lurched forward, hitting a concrete wall. The collision warning system did not alert, and auto-braking did not occur. The car was in Regen Level 3, and Auto Hold was not activated. In the months prior to this, the car twice had a similar situation when coming to a stop at an intersection with foot on the brake, then suddenly lurched forward, nearly rear-ending a car in front. There was no visible damage to the concrete wall, and a police report was not made. Hyundai says they want to inspect vehicle, but have not done so after a month. It is easy to believe that this was driver error, but it absolutely was not. Car lunged forward and accelerated into a wall with only the brake being applied. All of these events have occurred after the Hyundai Ioniq 5 software update was applied on 26 Sep 2023.
