Call up General Motors directly & talk to someone there. I have dealt with a problem dealership in the past that swears "they all do that" when I know that they are wrong.
It's a headache & I feel sorry that your going thrrough with it. Try going to other Chevy shops & see what they can find out. Don't give up, demand that it gets fixed or they won't get there loaner car back until it is.
Make GM pay for a loaner or take one of the dealerships if needed.
Do what you gotta do & don't take NO for an answer. Enough complaints should warrant it a lemon shouldn't it?
They should compensate you for all of your greif.
