Hi and welcome aboard!
The estimated range miles you are experiencing is due to 3 major reason and not a cause for alarm.
1. The batteries do not hold a full charge in colder temperatures (battery chemistry and common for all EV cars).
2. Use of cabin heating seriously depletes battery charge (heating uses resistive heating that draws direct power from the battery).
3. The way you drive also affects the range (heavy foot, jack rabbit starts, terrain, etc).
The guess-o-meter that estimates the range can be altered during the drive by:
Turning off the cabin heating (climate control), drive economically in ECO mode, and storing the car overnight in a heated or warmer area.
I am in Southern California where we experience warm weather in the winter and do not see the drops that the rest of the country experiences.
So my range never drops below 47 miles and often time in the summer, I get 60-70 miles per charge.
