My 09 toyota rav4 ( bought last august in queens new york) had the same kind of problem that, the car speed up suddenly and almost punch the front car when i was pushing brake, stopping and waiting for traffic light from red to green. it were happened two times last year, and also, sometimes, when the car is running on the way, the speed suddenly up. i think the problem is caused by it's control system like software poor design in anti-interfering/electronic noises. *tr
