Just curious if anyone here has experienced the issue of their battery going dead if their 05-06 sat for a while without being driven.

This happenned to me twice now in the last two months. I read on other forums after the first time I had this happen that this is not uncommon, and is being experienced by many new Mustang owners. Some say the Shaker stereo, if left on when turning off the car is the issue, however the last time (yesterday) my battery was dead, the Shaker had not been left on.

Also my driver side window lost it's calibration and will not re-calibrate after the recent battery drain. The window now 'bounces-back' when reaching the top of it's travel. I disconnected both battery cables for longer than 15 minutes and tried to re-calibrate, but it still bounces back.
