I purchased my 2017 Bolt in August of 2019. It now has 50K miles and I drive about 6K miles per year. I do not know the maintenance history, if any. Now I am trying to figure out if I have a "first design battery" or a "second design battery". According to my VIN # it appears I have a first design battery -- if it had not been replaced before I purchased the car. I have a VIN# before the VIN Breakpoint (1G1FX6S06H4163254) where they started using the second design battery.
I ask this because I understand that the first design battery had an inherent problem: Bolt 2017 reports greater range than I actually have and may run out of battery power while driving. Does anyone have any background on this? (For background see WeberAuto at:
