Driving on us 19 at approximately 50 mph when my car accelerated to 70 mph. I applied the brakes and it slowed back down and was fine after that. On December 5th I was stopped at a red light when it suddenly started to accelerate and I had to push hard on the brake pedal to keep from going into the intersection but, by the time the light turned green it was back to normal. I brought it to sun Toyota and they could not find anything on the computer. They cleaned a part that they found to be dirty and said everything checked out fine. On January 9th I was pulling into the parking lot of sam's when it accelerated suddenly again and I had to use the curb to get it to stop. On January 18th I was at red light and it accelerated so loudly that the vehicle in front of me pulled over to the side thinking I was going to hit him. I put the car into neutral and it continued to rev and make a loud clicking sound. By the time the light turned green it had stopped and when I put it into drive it was fine. I went directly to the dealer and they gave me a 18003314331 #3 to call and report it because again they could not find anything wrong. I have parked the car and I don't know what I should do because I no longer feel safe driving it.
