"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 don't disagree that there's a lot of onus on Tesla owners to understand how their bazginamobiles function in the climate they live in, but there's definitely also a failure on Tesla's part for not having push notifications.
Having your phone ping you with a link to the car manual's relevant section on battery conditioning or w/e seems like it would be trivial for a company that removed Disney+ after Musk had a temper tantrum. Teslas probably even have external temp sensors that could do this automatically rather than Tesla having to do it manually based on regions' weather forecasts.
