They never heard of it? Haven't they seen the news reports of the runaway Toyotas?
The idiotic engineers have removed the two-ounce common sense throttle cable that rarely caused a problem and replaced it with a sensor on the gas pedal that feeds a signal to a very insane complicated computer which activates a motor to turn the throttle on the engine. This is just screaming for problems and a lawsuit.
Anytime the position sensor on the gas pedal and the position sensor on the throttle assembly do not agree, the computer is supposed to go to a default condition for safety. That's what's happening in your car. The good news is it resets when you turn the ignition switch off and you figured out that works.
One thing to observe is if your foot is on the gas pedal when the problem occurs. That will cause a disagreement between the two position sensors. If that isn't the case, suspect an intermittent gas pedal position sensor.
