Genesis G80 Acceleration problems by year

While driving at highway speeds (55-73 mph), the vehicle has repeatedly and unexpectedly applied the brakes on its own and on at least one occasion experienced a loss of power. These events occurred without any vehicles, pedestrians, or obstacles present, and without any driver input. Road and weather conditions did not warrant braking. On multiple occasions, the vehicle suddenly decelerated while adaptive cruise control was engaged, then immediately re-accelerated back to the set speed. This created a serious...

On Oct 14, 2025 I was traveling on route 287 north in cruise control set at 67 mph. Suddenly the dashboard screen went black and the car floored itself. The gas pedal went to the floor. It took a few seconds to realize what was going on. When the dashboard lit back up I was going over 100 mph. I quickly applied the brakes which disengaged it. It never happened again. The car is currently at the dealership but they could not reproduce the problem. They said it did not throw a code either. I felt it was important to report this so I am.

I was involved in an auto accident. The front driver side quarter panel was hit. No airbags deployed in either car. Immediately upon the collision, I tried to stop the car, but it accelerated on it's own. The car would not stop. I made a split decision to pull into a parking lot and then contemplated driving the car into a tree to stop it. I then decided to drive over a curbed divider that had a 3 foot hedge. I got the car to stop 8 feet after running over the hedge. I have no idea what happened, but did...
