Some kind of parasitic drain is possible, but have you had the battery itself checked? If the battery won't hold a charge, that might be a part of the problem. Also, your alternator might not be putting out enough juice to charge the battery.

Does the car start if you get a jump?

I have a 2013 Buick lacrosse and I have the same problem. The more I research they more ppl I have found withering GM/Buicks that have the same problem. No one gas an answer and the manufacturer has no answers either.
