2015 Toyota Sienna Cruise Control Problems

I was at a stop light when I slowly started to lift my foot from the brake pedal. The engine started revving up and accelerate. I pressed the brake pedal normal , then harder when it would not stop revving. I looked down to see if I was hitting the gas pedal by accident. I was not, about after 5 seconds it stop revving. I went about a foot and nobody was in front of me. I going to have it checked out by my dealer. This happened before and I thought it was driver error .When I thought I was hitting the gas pedal and brake pedal. I searched for incidents like mine, but could not find something exactly just similar. I did not look at the dashboard so i do not know if there was a message . So I'm reporting this incident to get answers and alert others of this issue.
