Water intrusion caused corrosion of the main engine wiring harness which caused a fault in the auxiliary 12V battery and has made the vehicle undriveable. Toyota cannot determine the source or cause of the water intrusion even though I have brought in the vehicle for routine maintenance since I purchased it and I have complained about a problem which is related to the auxiliary 12V battery several times in the past. This seems to be a flaw in the 2004 Prius design.
