2012 Volt with almost all options including Nav, #105788.
A picture is worth a thousand words:
Am out of the country currently, my wife will have to bring it in after dropping the kids off at the daycare.
Will update when I have more information. Am grateful that we decided to lease at this point.
*Edit: We just picked the car up Saturday evening (4/14). Car was running fine even with the error message, except no charging was possible.
*Edit2: Turned out to be a leaking battery coolant pump which was replaced under warranty. Great service from Volt advisor and Terry Thompson Chevrolet made the situation much easier to get through in the end. Repair took 2 days.
