Starter problems of the 2010 Toyota Sequoia

Vehicle was started and put into reverse. The vehicle immediately began to accelerate. Brake was stepped on and depressed with both feet, but the vehicle continued to spin tires trying to accelerate to a maximum speed. Vehicle was then thrown into "drive" and the vehicle attempted to accelerate to a maximum speed forward spinning all four tires (when not in four wheel drive). The vehicle was then thrown into park and shut down. Later that night (while the car was parked and unoccupied) the vehicle attempted to start itself. The headlights and interior lights turned on and off while the vehicle attempted to spin the starter. The vehicle did not start as it also appeared to drain the battery. This continued for approximately 5-7 minutes. Additionally, the interior equipment such as the radio and speakers turned on and off while this electrical issued was going on. Eventually the car's battery failed and all of the abnormalities stopped. I have not started the vehicle since, and it will be brought to the dealer. . . .
