    Most likely, the inverter coolant pump has failed. Your car should have been included in the LSC which will replace that pump at no charge.

    Check the inverter coolant reservoir when the car is IG-ON. You should see turbulence in the fluid which shows the pump is working. If you do not see this then the pump definitely needs to be replaced.

    Whether or not the inverter pump was already replaced, I recommend that you verify for yourself that the pump is running, via the visual check that I described above.

    If the pump has failed, then the car will work OK until the inverter overheats.

    You probably inadvertently rebooted the system by restarting it, however the inverter system coolant pump should be paid close attention to in summer. I will not go into this subject or rebooting as there is already plenty of threads on both subjects. Just use Priuschat SEARCH. :D
