This problem was being recalled. However, it was not fixed correctly. It was not a carpet or pedal problem as Toyota claimed. The car doesn't slow down even on flat surface. Most cars would gradually slow down, but it does on this car. On declining slope, it even goes faster and has to press the brake very hard to stop. On inclining slope, it still accelerates even you don't step on the gas pedal for a moment. The car still charging forward from time to time.
