Greetings! I need help! I drove my 2014 BMW I3 today with no problem. I get out the car. Go in the building for 15 minutes, I come back outside and the mirrors were still folded in like the car was lock. I hit my FOB to unlock my car, nothing. I grab the handle and the door was unlocked. Get in the car and everything was black, no power no lights. Please help me!
