Since January 13, I have had my battery die on me 4 times (including the first time) - twice in January and the others a few months in between. It never sat for more than a few days. Brand new car end of November 2012, so it was only a year old. I think there may be some discrepancy between the battery and where you can plug in your ipod for music. . . That's the only thing that was 'left on'/plugged in (I checked every time). The Toyota guy said that shouldn't be issue, but nothing else makes sense. I even went to a battery specialist guy and he said something was just slowly draining and a good charge overnight would do the trick.
