About three weeks ago the battery was replaced in my 2019 Bolt at the dealership where we purchased it new. The experience was without a hitch and the Bolt was performing well as the initial weirdness of the GOM disappears as the computer relearned our driving technique. Saturday we were charging on our home 32A level 2 charger when we had a power outage. A continuous beep started emanating from the Bolt until we unplugged. Charging was nearly done when I checked but the “Service high voltage charging system” message appeared. It can be dismissed with a check mark ✔ but returns with each start and the orange “Service car soon” stays on continuously. I checked coolant levels and the front passenger side battery coolant tank level was very low (about 1/2” from empty). I filled it to the full line with proper GM 50/50 coolant. I plugged in my ODB2 reader and it does show a fault but will not display a code number. Erasing does not make the code disappear. I can get the car checked by an EV tech for a week, so I’m hoping the computer will reset after 50-100 miles as in ICE’s if the coolant level was the problem. Any advice/comments?
