The braking system failed. As I was attempting to park my car, with my foot on the brake, the vehicle suddenly lurched forward unexpectedly, hitting the parked car in front of me. Both my vehicle and the parked vehicle were damaged. If anyone had been in the car's path, they would have been injured. My vehicle bounced off the parked car and continued lurching forward while I actively tried to stop the car by applying the brake. At no point during this incident was the accelerator pressed. No warning lights, alerts, or messages appeared on the dashboard before or during the event. Have not yet taken my vehicle to the Honda dealer.
