Sounds like a high battery drain issue. Seems to be a gremlin plaguing all of their cars. Issue is that the car doesn't "sleep" after you turn it off, draining the battery, etc. Has happened to me on 2 cars. On one, fried the car and was in the shop for a month. On other, they couldn't find so they tried to blame me (obviously) just trickle charged the battery overnight and it didn't reappear. Sorry that it's happening to you. Keep us posted.
