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

To all of you who've posted:

The number that shows in the middle of the green bar is a GOM (GUESS-O-METER). The only real measure of your battery's state of charge is the level to which the green bars behind the GOM have risen. If those green bars are topped off, the battery can accept no more electrons. Period.

Your actual range will be determined by how you are driving and with what creature comforts (AC/heater, seat heater, radio, etc.) you have engaged. The number posted on your GOM reflects the manner in which you have been driving over the last several hundred miles, giving the computer a guesstimate as to how far you might go on the current state of charge.

We charged to 100% yesterday and drove about 200 miles, Cruise at 68 MPH most of the time, a couple of sections driving at 70 MPH.
The estimated Range doesn't tell us much.
What was disappointing was the miles/kWh of 3.2 for the trip, 2.9 for the first 20 miles. That is usually 3.8 or 3.9.

It was cold (by Northern California standards) and foggy the whole time.
The "Max A/C" button was engaged all the time. "Heat" was engaged most of the time, although I think that happens as needed with Max A/C.
Climate was set to 73°F, because anything less than that seems to blow cold air (an oddity of the Bolt that doesn't happen in our LEAF).

Okay, so miles are interesting. We typically charge to 95%, 247 in moderate temps, 220 miles in warm temps, 207 this morning.

2.9 is normal for winter. I had 2.1 last week when it was 31 below zero.I can usually get 145 mi. With the heater off, the hand warmers and heated seats on. For the purpose of saving energy I never go faster than 60. I tested range v speed a few years ago and found a 10% drop in range for every 10 mph above 60.
