Haha I just posted about this problem today.. Hopefully this problem is known as well as a fix. Curious, did you notice it on a cold day cause I first noticed it after one of our cold spells here in VA.

This happened to me as well.
Turned out the exterior light switch was faulty. Had both switch and battery replaced under warranty. Attached is a picture of the service advisor's write up.
There is a DIY thread for to replace the exterior light switch.
I also now leave the exterior light switch on auto.
- passenger parking light stays on after car is turned off even if exterior light switch is on off position
- the battery eventually drains and no longer charges
