The contact stated that after exiting a car wash tunnel and parking the vehicle on the side of the car wash building, the vehicle continued to roll forward at a high speed without warning. The contact used both feet and excessive force on the brake pedal to stop the vehicle; however, the vehicle continued to roll forward. The vehicle ran over the parking pillar and crashed into a brick column attached to the building. The vehicle continued to roll forward after the crash and eventually stopped once it rolled over the car wash road indentation. The contact reversed out of the car wash indentation and called her husband for assistance. After her husband arrived at the scene; the vehicle was driven to the residence without any further issues.

The failure mileage was approximately 111,817.”
