After you do jump start it, go and get the charging system and battery diagnosed. First see if there is a problem with the alternator or battery themselves.I just changed my original 2012 battery this past Spring.Then, move on from there.

Your HFM module (blue tooth) could be draining it.  Common problem.  Pull fuse 131 under the dash on the passenger side.  Charge it.  If it does not go dead, then that is your problem.

Replacing the battery might fix all of these issues. When the battery gets faulty, all the gremlins start showing up.

 

When mine was showing similar symptoms, all I could think was about how much replacing the Bluetooth module would be. There was also a rumor that the battery temperature sensor (What?) was faulty. 

 

I took it in to swap the battery for a new one- all my issues went away.

 

My gremlins were that the volume knob wasn't working well (What's in have to do with the battery dying?!?!), and the radio kept resetting in the week prior to the battery failing on me.  After that, the car wouldn't recognize the key fob for key-less entry ("service keyless entry system" warning), and finally, it wouldn't start, and even after jumping, couldn't even hold idle without stalling. After the battery was swapped (no issues with the alternator, thankfully), I've not had any issues with the radio stack. Goodyear did mine for $145
