NHTSA Complaint #11611652 — 2017 CHEVROLET VOLT

Without warning, my car stopped charging. Noticed it was at 0 miles despite charging it the night before. Believing I may have not properly connected the home cord (supplied by Chevy) to the car, I chalked it up to being my mistake and plugged in again the next night. Same result. 0 miles. Then it immediately started acting like a 12V battery failure with engine warning lights and then it just refused to start and/or charge and was dead in the water. I called AAA for a battery jump and they came. It got the car started, but the check engine light remained lit for two days and I primarily ran the car on its gas generator to hopefully charge it. Just last night, the check engine light went away. Despite having a partial charge, this morning 8/29, it registered 3 miles down from being higher. I just plugged in to my home outlet using the chevy cord, and again, it would not charge (no green light on dash indicating active charge and a message on the dash should "unable to charge". I suspect a Battery Energy Control Mondule (BECM) failure which seems to happen with this car. My 12V ACDELCO battery is relatively new (3 yrs) and not used heavily (given COVID).
