Regen on Demand Paddle not working at beginning of drive (2017 G2 Premier)

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.

2017 G2 Premier 1 and 2 pkgs, ACC

Anyone else experience this?

If you hear something rev up when you hit the paddle, your engine is probably running due to temperature (ERDTT). Hitting the paddle disconnects a clutch in the drivetrain causing slightly less load on the engine, thus it revs up. That causes the engine to generate slightly more power, which leaves less "room" for the battery to accept regenerative braking power, so the paddle feels weak.

If it's 20 *F, you can go into Vehicle Settings > Climate & Air Quality > Engine Assist Heat and choose Deferred. That will prevent the engine from running above 15 *F.
