Welcome to the forum! Coby7 has already given you some great insights into what may be happening with your vehicle; if I can look into anything further (check into warranty or recall information for you, assist in working with a dealership, etc), please let me know and I will get you my email address (as you're new to the forum, I don't believe you can private message quite yet).
Sarah, GM Customer Service
