I haven't driven my volt for about a week, I started her up and noticed a check engine light on and a reduced power message on the display, ICE running continuously. (plugged in as I was conditioning the cabin) Big blue on star button is now my friend. Advisor came on line and ran a diagnostic, informed me that there were 25 fault codes all pertaining to the battery pack. I think she mentioned one that pertained to individual cells within the pack itself. Range was showing zero miles and the battery display on the center screen was greyed out. I noticed a few days prior that my remote link was showing a reduced battery range. I didn't think much of it and checked it again this morning and it showed a range of zero miles. 240 volt charger showing a good status, green light on the dash flashing slowly. I guess the dealership will be picking up the volt in the morning. Anybody else experience this?
