Driving last night on a depleted battery, ICE running. About 5 miles later while stopped, window open and stuffing a letter in a mailbox the Check Engine light comes on and the Center Stack Display switches by itself to the Nav Address Book screen, Weird.
This morning the light's still on, and I haven't done the software upgrade yet so I make an appointment to get both taken care of next Monday. The dealer calls back. Can't do it.
The out of state Volt they bought with 100 miles on it is in their shop waiting for a new battery! Apparently they have been fighting multiple error code battles for over a week and GM is bringing in some techs and a new battery.
On the one hand, that's a bummer. On the other hand they are getting a rare treat: removing and installing a new battery pack. If I was the technician I would be pumped. If I owned the car, not so much. A week without my Volt would trigger some sort of withdrawal symptoms, like always wanting to drive in L, haha.
