I noticed yesterday that the Onstar light on the mirror was on even though I hadn't driven the vehicle for two days. I don't recall seeing it on for more than a few minutes after shutting the car off. Before starting it I checked the battery - 11.5 volts. It started but turned over a little slow. The light is still on this morning after driving it last night. I also tried pressing the "phone" button without putting the key in. I got the "Onstar Ready" message. I never tried this before but I thought the key had to be on to make a call. Any thoughts?
