Took vehicle out came home. Turned vehicle off then went inside. Came out later and saw that dash board lights were still on. Nothing else was on (dome lights, radio, heater, etc.). tried looking for something open, (door, etc.). looked in maintenance manual and couldn't find solution. So figure I'd just start vehicle up then turn off. After starting vehicle I then went to turn off but engine won't stop running. I was even able to pull key out and vehicle kept running. Drove it to nearest Toyota dealership where getting repaired.

While driving my 2010 Sequoia we hear a clicking sound coming from the driver side vents and under the steering wheel, a second later the radio goes out. This event happened several times. Brought it to the dealer, they reported they could not find anything. Brought it back to the dealer several times. They report could not find anything. The last time we brought it in back to the dealer we hard several clicking sounds the radio went off, we had our phones plugged in the charger and they went off, the air went off and the dash lights went off. It stayed off for several minutes and then we heard the clicking sound again and everything came back on. We have 4 video recordings of this happening and we showed it to the service department and they still reported that they found nothing. Worried it may lead to more electrical problems.

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....
