Did you inspect the vehicle before delivery? A few of those could have been avoided by a quick inspection.
Anyway, sorry to hear this. You need to demnand the dealer /GM to buy back you vehicle. If they refuse to do it, the Lemon law will be your biggest friend. Again, sorry to hear this. There's a few in this forum with ATSs and they have been overall reliable except for a few problems and a very known Lemon. It can happen with any brand, really.
