During my morning commute the Battery Saver Warning message appeared. On page 135 in the manual, it says that my 12 volt battery voltage has dropped and vehicle features are being disabled. The message may also display when the high voltage battery is low. In my case I still had over 200 miles on the GOM and none of my vehicle features were shutting down. I called ONstar and they said my diagnostics were fine. I have a Monday morning appointment for my Bolt. I have since stopped the car when I arrived at work (my commute is 74 miles). The message reappears when I restart the car. I drove over to the nearest dealer where I work and they said we can't look at it for a week. I am going to drive it back home tonight and cross my fingers. Anyone else had this message appear, preferably without it being an issue of the traction battery being very low. My home dealer has set up a loaner car for me for Monday while they service it.
