Since I've been at college this past year, my 2006 Toyota Highlander Hybrid has been parked in my garage back home. When I went back home in December for Winter break, the car drove perfectly fine. I went home last week for Spring break only to find my car battery dead. Nobody else in the family drives it while I am away, so I am certain that no lights were anything left on in the car.
Does the battery of a hybrid car die every time you leave it for any period of time?
