I am told GM can't do over the air updates on the Bolt except to the infotainment system, and they have never bothered to do that. Have you had any of the recalls performed yet? My 2020 Bolt LT has not been made eligible for the recall battery replacement or even the interim software that limits full charge to 80%. If you are in an area with cooler weather you might want to check to see if you have the auto defrost function enabled. Some folks have seen a significant range hit when that activates. I have just been seeing the lost of miles per kilowatt hour that comes with cold weather and heater use. I don't charge to 100% since the recall, just 90% per GMs recommendations so I can't compare my range, and there are too many other variables to make a comparison valid.

I normally charge to 80% for local trips (although that tidbit is missing from the manual/display unlike the Leaf & Tesla). When I charge to 100% last month it was still about 260 miles, now this week it dropped to 210 miles. I read that there were some battery issues at 100% (maybe because they didn't tell folks to charge to 80% for local use). The battery was advertised as 64KWH although it's stamped underneath at 62KWH but now behaving like a 50KWH or 80% battery pack. I wonder if the Mother Ship downloaded a 80% operation through OnStar that it has (but I didn't pay for)? Has anyone had this happened on their Bolt. I was going to buy a cheaper 210 mile Leaf, but bought the Bolt for the longer range, oops - now the same as the cheaper Leaf. The Tesla Y at the same 21K miles is still doing 325 miles range and charges *much* faster (up to 200KW pre-cooling the pack), more fast charging stations through the easy to use GPS.
