I noticed a similar issue with my 2016 Premier model, although I live in Southern California and do not experience temperatures in the 20s. I found that in our winter (temperatures below about 50 degrees F in my garage) the regenerative braking (either by the paddle or by using the ‘L’ position) didn’t work for the first couple of minutes or so of driving. I recently took the car in to have the ‘reduced propulsion’ and ‘front camera freezing’ software updates. Since then, even when temperatures drop below 50, the regen has always worked immediately. Also before these updates, the ‘maximum startup volume ‘ setting for the radio in the radio settings never worked – whatever I set it to, the radio would always start up at a very low volume. Now it works fine after the software upgrade. Strange. I’m not sure if this applies to a 2017 Volt.I noticed recently that my regen on demand paddle does not seem to be working at the beginning of my drive below freezing (20's) for maybe five to ten minutes.
When I press the paddle (D or L) foot not on the go pedal, I hear something rev up, no idea if engine or a hydraulic pump. I think the engine has been on each time this happened. Later, it works normally.

Anyone else experience this?
