Just got off the phone with GM and they have done all they can do she said. They have documented the occurrence and business transactions from the warranty/sale of the car. They were very apologetic and sent me a manufacturer's service coupon for $100. They said the dealer is a private business and there is not much they can do but help in discussions and document what happens. Still waiting to hear back from the dealer, but gm said I do owe the dealer the deductible still.
