A call to Toyota Agency in Stockton revealed a STUPID FLAW in the Prius.That seems like a pretty important flaw. If nothing else, they should provide a "cut-off" for the small battery so that you can easily leave it shut off over an extended period of inactivity and then easily reconnect it later.
It has only a 12 volt auxiliary battery which starts the car, then the big battery takes over. It is not uncommon for people leaving a Prius at an airport to come back and find it dead! To me, the solution is do not take it to the Airport. But if you leave it home, you should have someone disconnect the battery, otherwise it will die at home...was the advice of the Service Manager. If not driven 3 - 5 days, it is not uncommon for this to happen...it can also be jump start by another car.
Bottom line is that I do feel much better...I do not have to be afraid of driving it around here.
