My wife was parking the 2024 ioniq and it lurched forward at a high rate of speed and slammed into another car parked in our driveway and drove that vehicle through our home garage door. She feels certain that her foot was on the brake, but even if she accidentally slipped and appleid the brake the forward collision system should have prevented the accident additionally the impact occurred with such force it is unlikely due to human error as it pushed our very heavy 4Runner back 3 feet and thorough a closed garage door.

Backing vehicle out of driveway and went to engage brakes and they did not engage. began rolling backwards down street with steep grade. Kept stepping on brakes with no response. Had to turn into a parked vehicle to keep from rolling down steep grade and potentially off a substantial cliff. Happened today and dealership said that it may be because the "battery for the brake" had not received a charge from the main battery. Very dangerous and never disclosed. If I had not taken evasive action I could have easily been killed. Car is being dropped off at collision center today but is available for inspection. There were no warnings or other symptoms.
