I don't know which system failed or malfunctioned. It is available for inspection. While parking at the community parking lot the car accelerated. I wan't able to stop it. It jumped a bumper stop than a curb and drove up a berm and crashed into a tree. (The incident is on film at the clubhouse). I was the only one injured. My knee broke the underside of dashboard (see phpto). I did have other bruises. The vehicle is still at the collision repair shop so it hasn't been seen by the dealer. However I did report the matter to American Honda who assigned a case #13707324 on 3/17/2023. As of this writing I am told they haven't assigned same to a representative. To the best of my knowledge the vehicle has not been inspected. There were no warnings given.
