I've had 2 incidents recently with my '01 Prius and the accelerator, but have not found the same problem described here. I don't have the uncontrolled acceleration, rather the opposite. Both times happened after an hour or two of interstate driving. After getting off the interstate and driving around 30 miles per hour for a while, the warning lights come on and the car stops responding to the gas pedal - that is, you can have it floored, and it'll go about 20 miles per hour or less. It'll jerk forward (speed up quickly) a little, but not to any fast speeds. Both times, this has lasted until we turned the car off for half an hour or so, then it's fine. A day later, the warning lights go off. Any help? The local dealer just told me it'd cost $128 just to run the computer diagnostics and he wouldn't bother until it happens more often. At that point, I figured he was not the guy to go to for advice.
