Corolla 4-cyl

2003 Toyota Corolla. Consumer states problems with vehicle accelerating. The consumer stated she was traveling at the posted speed limit, when the sign ahead indicated to reduce speed ahead. The consumer reduced her speed to the posted limit by pressing down on the brake. As she attempted to brake, the vehicle continued to increase in speed and a loud noise was present. The consumer stated she continued to press harder on the brake and she could feel the ABS activating. The ABS sounded like a high pitched noise and pulsating very fast. The consumer finally came to a complete stop, before going through an intersection. However, the engine was emitting a loud roaring sound. The consumer shifted the gear from drive 1 to drive 2 and the vehicle shuddered. She tried to shift to park, but as she got to reverse the vehicle tried to buck, so she put the gear in neutral and turned off the vehicle. Updated 08/10/11. The dealership maintained the problem was the driver side floor mat and driver error. Updated 08/23/11. Updated 09/29/11. Upated 10/11/11.

While applying the accelerator pedal vehicle failed to accelerate. Consumer applied the brake pedal and the vehicle accelerated uncontrollably. Vehicle was taken to the dealer for inspection, and mechanic determined that the transmission fluid needed to be replaced, and replaced it. However, the problem recurred, and the vehicle was taken back to the dealer. However, mechanic could not duplicate the problem.

My 2003 Toyota Corolla experienced a sudden acceleration problem twice. The local Toyota dealer and Toyota's field technical specialist refused to believe the car would have accelerated by itself unless I had pressed the accelerator. No way!!!! they said it was impossible for the car to have picked up self-acceleration. They were unable to pinpoint any problem. This is a very dangerous situation! I was lucky nobody was hurt or killed.
