Are you still under warranty? If so, I'd take it to the dealership. If not, I'd have to check the battery and charging system.
Another possibility is too much drain with the key off. Usually less than 50 ma, that.050amp, not even a tenth. If the drain is too much, you pull/replace fuses one at a time. When you pull the fuse on the problem circuit, the excess drain goes away.
Sometimes it can drain through the alternator?
