4 Accelerator Pedal problem

Failure Date: 08/12/2004

Accelerator fails to respond for 1-2 seconds in an emergency acceleration situation. When entering a road from a stop sign, I hesitated thinking there was no room. A vehicle let me in. When I hit the accelerator to make it safely, the vehicle failed to respond for 1-2 seconds. The car letting me slowed down to let me in, but not enough to allow for this delay and he nearly rear-ended me. It was scary to not have the car respond. I have seen many other complaints filed about this and the dealer response always seems to be that this is how the electronic throttle control performs. I believe this needs to be recalled so that Toyota can make this electronic device respond immediately as opposed to taking 1-2 seconds.
