"Nothing. No juice. Still on zero percent," said Tyler Beard, who has been trying to recharge his Tesla at an Oak Brook Tesla supercharging station since Sunday afternoon. "And this is like three hours being out here after being out here three hours yesterday."
"Like any new technology, there’s a learning curve for people," said Mark Bilek of the Chicago Auto Trade Association.
Lmao, no my dudes, it's pretty well understood that you need to keep the battery warm enough to be able to charge. This is not some fucking unexplored field of science!
I'm absolutely cackling at the radio silence from Tesla + dozens of Tesla owners just sitting around cluelessly wondering why their car hasn't charged at all in over 3 hours. Maybe another 3 hours will do it, keep trying 
Also, a cursory Google search leads me to believe that the Model 3 has no dedicated battery warmer that could be used for this very situation, but instead some system that "runs the motor inefficiently to heat up the battery". Doesn't sound like this can work when the car is stationary, I guess tesla engineers forgot about the Midwest when cutting parts to save on production costs 
I've got a Volt too, great car, built like a tank in that the battery sacrifices max range for lifespan.
Ive owned mine for 5 years now and have done zero maintenance on it aside from 2 oil changes and replacing one battery cell at a cost of $2k. I’ve driven it 50k miles in that time. I just took it in to get looked at because it’s been a while, they topped off the fluids and said it’s in great shape. Amazing car. Uncomfortable as hell but great car.
