“2003 Toyota Highlander, I have a randomly occurring problem with the gas pedal sticking when you are trying to accelerate from a stop. My year model is not included in the current recall but I wanted to make you aware that there are other possible problems out there. I have called the dealership and they said without being able to duplicate the problem there is nothing that I can do and it is randomly occurring.”

“Saturday june 18 2016 at 6:40 a.m. Driving on tully road in my 2003 Toyota Highlander. My speed was 35 miles per hour when the car suddenly accelerated at a high rate of speed. I applied my brakes to slow down the Highlander this had no effect on slowing down the Highlander. The brakes went into anti locking mode the wheels started to pulsate. While this was happening my foot was not on the accelerator , but on the brakes. The Highlander was not slowing down but increasing speed. I down shifted into a lower gear, the engine raced at a high rpms. …”

“On 7-11-13, going at highway speed on route 52 in north carolina, the throttle became stuck wide open causing my car to accelerate beyond my control. I slowed down to get off on the side of the highway, but I could not stop the car, only slow it down, to approximately 10-15 MPH. Got back on the road and took the next exit. Again I could not stop the car, and though I slowed again to about 10-15 MPH, I drifted through the intersection at the stop sign, with traffic approaching from both left and right! …”

“Pulling into a parking space at kaiser hospital as I hit the brake the car unexpectedly accelerated. The car sped forward while my foot was still on the brake. I hit a tree causing damage to the left front area of the car (lights, fender, bumper) had car repaired. At the time I thought that I had accidentally hit the gas pedal;however, one month later while approaching an intersection, as I stopped, the same thing happened. Luckily no car or pedestrian was in the intersection. I was able to stop the car by shifting into park. Took the car to my mechanic. He was unable to replicate the problem. …”
