When backing into a parking space with my foot on the brake, the rpms surged causing speed to increase suddenly. I place the car in neutral and the rpms continued to surge for about three seconds and then returned to normal. While waiting at a traffic signal, with my foot on the brake, the rpms suddenly surged and I again placed the car in neutral. The surge continued for about three seconds again. On one other occasion, when shifting from reverse to drive while exiting a parking space, the rpms surged for about two seconds and then returned to normal. The vehicle seems to accelerate suddenly on its own without depressing the gas pedal.

While stopping the vehicle sometimes the brake distance is extended as the car is slow to stop. On a regular bases the vehicle brake pedal sticks to the floor while stopped at a light, I then have to pull the pedal up with my left foot to begin acceleration. When approaching slower traffic as the traffic resumes at regular speeds the brake pedal sticks and continues stopping the car.

Unexpected acceleration. On several occasions, primarily while stopped at a traffic signal, my vehicle would lunge forward. I took it to the dealer and was told they had no record of a problem of this nature for this vehicle. They could not find anything wrong. I saw a article on the internet that the NHTSA was investigating similar problems with other Toyota products.
