Hi all! I'm a newbie here so my apologies if this has been discussed. I just got the 2017 Prius Prime a few weeks ago and live in MN where it got REALLY cold really fast. I'm not sure if that's the culprit here. My "issue": my drive to and from work is a total of 12 miles. Before the cold snap, I was getting 28 miles on the charge and the car's electric mileage decreased as I drove it - this was in both "EV mode" and "EV auto". Since the cold, my car has started it's charge at about 24 miles and literally will not move from that position or goes a little down and even up in mileage!! It's so confusing to me. I don't know if it's switching over to gas during this time but it doesn't seem to show on my gas gauge that it has and still displays "ev mode" or "ev auto" on the dash. Also, I was told not to charge the car unless it's needing one. After I get home, and the car is still at "24 miles", it prompts me to charge immediately. Thanks so much if you have any insight to offer to this very-confused first timer!
