:( It sounds like your car is an exception. :(
I'm sorry to hear about the issue's you're having. But "keep the faith".
Stay in contact with your service dept., get names, including service mgr., and if necessary, contact a GM factory rep.
I'm sure GM will "do right" by you and your Camaro.
AS I said, it seems your Camaro is a unique case. I hopeful you'll be able to work with your dealer and GM to get everything resolved.
