general problems of the 2001 Toyota Sienna

I had just dropped my youngest daughter off at school and as I was leaving I had to stop because some children with their parents needed to cross in front of me I applied my brakes as normal and I had no issues in stopping but then it feels like a "ghost" pushes the gas pedal down because I can feel it move and see my rpm gauge go up and I hear my engine "vrrrrooommmm" I pushed my brakes harder and still nothing, the end results me having to put my car into park to keep it from moving into the crosswalk onto the people. When I get home it does the same thing and I almost crash into my garage because the car is accelerating on its own and again. It would always happen at random, after I would let go of the brakes its already moving fast as if my foot is on the gas, I say to my passenger which is my wife "look the van is going on it's own, I'm not even pushing the gas" the van was moving pretty fast, but fast enough for the flow of traffic from a stop and go movement. I no longer drive the van because I am scared that I am going to get into an accident and I don't want that to happen. No check engine light is on I even had the van checked for codes and nothing came up.

2001 Toyota minivan unpredicted accelerated while driving on highway. Pulled off to exit ramp and did again so had car towed.

I was driving a 2001 Toyota Sienna. I turned left into a parking space and pulled forward. While still in drive, rather than stopping, the car continued to accelerate slowly, ran over a wooden parking barrier, and crashed into a concrete wall a few feet away.

Vehicle surged backwards at high speed when backing out of a parking space.
