Just like may other folks in the good ol USA, temps have been struggling to make it above freezing for quite some time. I have noticed in the past several weeks that I am only averaging 18-20 EV miles with a mix of the engine starting due to cold temps. After a full night charge my total range shows nothing better than 21... is this an issue or is this just part of the cold weather pain? 2012 w 46k miles. I guess I should also note a few things - the car is parked outside, i travel 18 miles one way to work, use the butt warmer at a level 1 and the heat at level one eco.

Cold weather pain. Happens with gas vehicles too. Moreso in fact. Just not as noticeable with a large gas tank.

I set my temp to 76F Comfort in Winter, in my 2013 Volt. I also disable ERDTT because my one way commute is 15 miles, and I charge at work. I also drive aggressively. My AER goes down as low as 25 miles in these conditions. GM once said that Gen 1 Volt range can be anywhere between 25 and 50 miles, which is right on the money. YMMV

Sounds normal, my 2011 with 109,500 miles shows 25 miles range. However it’s parked in a heated garage which never gets below 45 degrees. In 0-20 degree weather of late the heater is on comfort fan about middle and temp set to 72. Seat heaters used always. I smile when the ICE starts knowing that engine heat is helping my cabin heat. Come spring I’m expecting range to rebound back to 36-39 as usual.

Also, what's your tire pressure showing at those conditions? If you last aired up when it was 60F and it's 10F now, your 38-40 PSI then is flirting with a low-pressure warning now. And that can cost 5 miles of range.

it isn't even close though. EVs suffer far more than that five to ten percent a gas engine will suffer and it only gets worse as the gas engine warms up. I never had a gas or diesel drop as much as my Volt did just because it got nippy plus I didn't have to sacrifice for heat either

On my 2013, my results are similar to Telveer's (post 3). OP, if you are under 20, and that is with the help of ERDTT, that sounds just too low to me. I suspect there is another factor. Are you driving over 75 mph, in rain or snow, steep terrain, jackrabbit starts, with roof rack or trailer? If nothing like that, then I would suspect something about the car.

I'm an hour north of you and own a 2014 and park outside. In this stretch of weather, I got 25-28miles of range for a commute of 25 miles round trip. I use hold mode to heat everything up, then use battery.

Terrible compared to what, summer? Sure, winter has that affect on all vehicles gas or electric.

But as others have said, winter conditions drop winter mileage whether EV or gas. Traditional gas cars never showed me the affect of winter on my driving range while the Volt and Bolt EV do.

Given your short commute, consider disabling ERDTT with a cheap resistor. Make sure your tires are at 38-42 psi. Don't be afraid to use Comfort heat.

I live in NOVA too and I'm getting closer to 30 miles. When it was single digits, it may have dropped as low as 25. ERDTT adds quite a bit back.

After a full night charge, I've never seen less than 29 miles this winter. I have a 2013 with 50k miles that I keep in the garage and precondition when it's really cold. I use the standard charge cord at 13 amps. I travel 16 miles each way (charging at work again) and set climate to 76, comfort and seat heaters on high.
