Wow. I can't say I've had any of these problems, but I hope it all works out for you.
I just purchased a 2012 LTZ RS as a CPO vehicle. The dealership I bought it from was crap and wouldn't lift a finger to help. But I took it to a different dealership (in the town I live in), and they have been so helpful from the second I took it in there (even though they did not sell me the car)! After the oil change under the CPO maintenance program, they told me that I had a bad tie rod (which they replaced) and after that service, they told me that I would want to have some "leaks" fixed before the B2B warranty ran out. So, needless to say, I hope all of your issues get fixed! Good luck!
