Third time in 4 days that the battery drained overnight after driving the car the day prior for at least 30 minutes. Taking to dealership today, after having to jump start again. I went out to the car and put the key in and turned to the accessory position, it seemed a bunch of system powered up. I captured on video the battery level at approximately 12 and watched it drop to about 9 over a period of one minute. The warning system eventually gave me a low battery warning and it stated I should start my car, but too late. Had to jump it.

Update from Jan 31, 2017: Took vehicle to dealership. They fully charged the battery and then ran diagnostics and they said it was a bad battery so they replaced the battery under warranty. I had an autoparts store run a diagnostics on the electrical system 3 days prior to this and they revealed a good battery and alternator. I suspect that the problem isn't fully resolved but haven't had an incident since replacing the battery.
