I'm having the same issue on my 2009 Yukon SLT. Random errors on my display, has power but won't start and on and on. I take of the poss batt cable to get it to start.
I also have 2 cracks on my dash, very frustrating as I can never seem to get anywhere with dealers or mechanics yet I see the issue all over the internet.
