Had an issue with my new Stingray (GPS, Nav, and OnStar would not work). The Corvette forum listed these items as a fairly consistent problem for Corvette's build during a two month period with the performance data recorder - and several members stated that their Chevrolet dealers had trouble finding the issues and fixing them. Because of my trust of Hamon's as a dealer, and the Harmon's service department, I'm having my new Corvette serviced there. Dan and team researched the problem, read the codes, called TAC, overnighted the needed part, and had it completely fixed the next day. Another reason I have purchased several cars from Harmon's, and will always have my cars serviced there. I really appreciate the way we (and our vehicles) are treated there. I send all my friends there too.
