I have a 2002 Prius, for several years it would show "check engine" signal, and I would get various explanations from service department. ie Gas cap not tightend, battery too small, a leaf got pushed into some internal sensor, we dont know and we are not getting any signal, everything seems to be Ok. etc. Car is now at a different service department in Ukiah California, they have taken the problem seriously, checking and rechecking everything, keeping the car for over a week and finally getting some repair code. Prius is under extened warranty and they are installing new ECU at around 86k miles. I think the problems has been evident for the past several years, with random unexplainable symtoms and 5-6 trips to service to try and fix.
