Priority goes to people that still owe GM money. They have your money already, therefore you are last on the list, maybe not even on the list at all.Same here. Bought my Yukon exactly a year ago and they still owe me the parking sensors, sterring wheel lock and the seats option chips. Called the dealership and all they said is that I am on the wating list and should be receiving an email from GM when the parts/chips are available. Kinda frustrating when the new vehicles have the chips and I am still waiting.
