Since I made the original post the 12 volt battery would go dead every month almost to the day. If I charged it, it would last another month. When I forgot, my wife was calling ON-STAR. To make a loooog story short, the dealer replaced the 12 volt battery and disabled the Bluetooth and several months later, no problems. I kept telling the dealer and my VOLT adviser it's a software problem and it doesn't take months to fix a software problem. The car is a 2012 that we bought in April of 2012 so I would think it has the latest software. The dealer and GM should have checked it the multiple times it has been in the dealer for this problem.
I'm afraid to reactive the Bluetooth.
