I have a 2010 GS MN6 Coupe - Is there such a thing as a firmware or BIOS update to fix issues by GM for these?
These cars have several computers and with all computers I have ever owned they would get one or more BIOS or firmware update over the life of ownership.
Just curious - figured you guys would actually know better than my local dealer. Thanks
I know they can flash the computer back to stock and also reflash it for recall stuff and updates..or at least they can on other makes so I imagine GM can too.
