I own a 2017 Bolt EV and also
I own a 2017 Bolt EV and also no major issue so far, just minor issues with the center screen, rear camera display. Have put 57,000 Km on it so far.
Only items on wish list:
1. Better charging speed, given that newer charger capable of supplying 200KWHr or more, but the Bolt is still charging only at 41KWHr.
2. Less range loss in mid-winter would be nice
Otherwise, it has served its purpose last 2 years and quite happy with it.
