Most likely it will be totalled out. Hopefully you filed the claim with your own insurance and not the other guys...you will always get more for your vehicle that way.
I know what you mean about the issues with these cars. I have had my 2011 for about 14 months. Swaybar bushings swaybar links brakes and rotors all around wiper motor wheel bearings. Heater hoses sprang pinhole leaks at the quick connect fittings a month apart. Last month a new transmission now throttle body issues and misfires on 1 3 5 due to oil leaking into plug holes. A real money pit
GOOD LUCK and stay away from gm
