2023 Bolt EUV poor mileage

[cutenurse1]

This is my 3rd winter with my 2023 Bolt EUV and it will not charge above 170 range. The first winter it held around the 240 mark, the 2nd winter it charged to around 212, and now 3rd winter it is charging to around 170. WTH?? I can barely make it to work and back now. Why is this happening?

Update- now charging to 155!

This is normal winter range! In chemistry the rate of a reaction depends on time and temperature. Your lithium hydride is obeying that law. One trick you can try and the Chevy bolt that I have has a timing system that conditions the battery, warming it up to room temperature 69 or 70° f. Use that system before unplugging your Bolt. It will warm up the cabin as well as the battery. It takes about 20 minutes after which you can unplug it shut off the heater in the cabin and you will see the range jump up about 20%.
Once the car has had its battery warmed up initially it will continue for your entire trip. It did for me and my spouse when the outside temperature was 31° below zero occasionally you might need to turn the fan on if the Windows start to fog up but that's just for a few minutes and it will return to the original range

I disagree. This is my third winter and I never had such low mileage so this is not normal.

Sorry for your loss. Mine hasn't misbehaved for 8

What "timing system" are you referring to that warms the battery to room temp?

I have found the same. I warm the car up for about 30min when it is plugged in. Cabin is warm and battery is warm. It starts our at around 4mi/kwh. We use the cabin heater set to 66deg and it keeps the windows from fogging up as well as warming our legs.

I’m the very same for the past two years. Once it gets cold, my max charge is around 160. During the summer I’m around 245

Did you trying disabling the Hillside Reserve feature? Contacting the dealer? Contacting GM?

Factory recall downloaded into my car and limited my maximum charge to 80%. And there was nothing I could do about it because it was under recall. I seem to remember for 2 years the maximum charge was 220 in the summer and 190 in the winter. This is very similar to The hilltop reserve. Right now I have set both my cars to a maximum charge of 190 MI simply to reduce wear and tear on the lithium hydride
