...car keeps draining battery!? I learned that if I unhooked the cables from the battery that will keep my batter from dying. I took it to get the battery tested and the alternator tested and they both came back good. I'm afraid to leave the cables connected until I found out whats draining the battery, does anyone have any ideas? Thanks!

You have constant battery drains on newer cars for things like radio memory, PCM memory, the remote system and so on so trouble shooting it is trickier than older cars. Dave is likely correct there is a short or something is on all the time like an interior light or trunk light or possibly even the brake lights are on all the time (bad brake switch).

Probably the easiest way is to pull one fuse at a time once a day and see if it's dead in the morning. When the car starts in the morning the lst fuse ytou pulled is the circuit to look at. Works fine if you hve another car to jump it every day nd you hve the patience.

It's also possible one of the battery cables or grounds is bad. Could be a problem with the red wire from the alternator too.
