Zero battery indicated all of sudden

Cold weather caused your battery to be too cold. When the battery is cold it will reduce the available energy available until the battery warms up. How long had it sat for? How many miles were available after you drove it last?

That's the first!
Interior 59F is not that cold for S and X but I am not sure about Model 3.
Since there's a snowflake icon, we know that the car feels cold. So what's the ambient temperature that your car is feeling?
Where did the low charge warning appear (car's display screen or phone app) and what did it say "low 12V?"
I didn't know the battery gauge would show 0 miles when there's still about 189 miles.
If you do a reboot (holding 2 scrolling wheels on the steering wheel down at the same time until your screen reboots then you can release them), then see if the battery gauge would display some miles and not 0 miles!
Does your 15" instrument cluster also say 0 miles or there's the difference between the cell phone display and your car's display?
Very interesting!
I think it's a display bug with the Tesla app. Maybe try logging out and logging back into the app, I'd even try re-installing the app. If you're not close to your vehicle to physically verify, I would just call Tesla and see if they can remotely ping your car and see what it's reporting. It's bad for the battery to be depleted for an extended period if the status is accurate.
Ok I'm just going to say this for now...charge to say 70-80% and then show us what is happening...I'm not discounting what you are saying but with low battery SOC there isn't much margin for seeing what is really going on, especially with cold weather issues.

Looks like the reboot:
1) fixed the snowflake icon on the app (gone means no longer cold)
2) shows 34 miles on the instrument cluster (an improvement from zero)
However, it doesn't fix:
1) 0 miles on the app
2) Snowflake icon on the instrument cluster while the ambient is 64F.
3) 34 miles is too low if the last reading was 189 miles.
4) Instrument cluster error message: "Car needs Service. May not restart".
Guesses:
Did you just update your software? Automatically set it to do it during the night?
An incomplete update can produce "Car needs Service": but it looks like it is complete. So it doesn't make sense.
Action:
Charge your car back to 90% and if everything works normally, maybe it's just 1 unreproducible random error.
If things don't get back to normal after the charge, I would call Tesla and make an appointment to fix it.
Good luck!
If it was in the app and not in car maybe you just got some bad data over the internet....
The cold snowflake is highly unusual at that temperature. You may have a main battery failure. I would suggest contact Tesla asap
So you all, thanks for all the feedback but after contacting TRA, it was towed to service center, diagnosed and you all ready for this....a replacement HV battery is what's needed. Having the vehicle for a day shy of two weeks, it will be covered under warranty but jeeze

They have an improved battery now. What model year is your car?
