Hydraulic Power Assist Steering System Problems of Toyota Prius

I have a 2004 Toyota Prius I purchased used last Feb (06). Starting the car does not immediately bring up the dash display. It remains blank, however I can shift into gear. The power steering is off as well. I restart and restart and eventually the dash will pop on. The car is drivable but all the warning lights are not. Not at once though. The red triangle with the ! in between is always present but sometimes it is joined by the check engine light or the abs failure light. The Toyota dealership is still trying to figure out what's going on.

I have been given an estimate of time to repair ranging from 2 to 4 weeks because of unavailability of parts. Dealer's service department feels that the car is unsafe to drive. Steering wheel experiences "minor jerks or tics". Service writter says this is because of errant electrical signals being sent to power assist.
