F that dealer. Never give them any more business. A SSN error should have been a warranty claim and they should have followed any FSAs and updated your modules under warranty. It would probably have taken less than 30 minutes with a laptop and IDS to update the modules. I suppose I could be wrong since I am only speculation on what it would take but it sure smells like they are just trying to shake you down.
