Thanks for taking the time to write this and for the insight.Note: This is a bit long but I hope worth the read.
Sorry I can't tell you about any Genesis dealer in the RTP area or eastern part of NC, but here in the Piedmont/Western part, there is only one truly Genesis-named dealership and that's Keffer in Charlotte. I bought my Genesis as CPO from Lake Norman Hyundai and I have taken it in once for an oil change. A little convoluted because we also have a Sonata (purchased new from there), and my service actually started because of a service question about the Sonata I could NOT get an answer from on the phone, so I drove there. The dealership usually has about six or so used/CPO Genesis in stock but I have never seen a new one on the lot. One of the asst. service managers is a friend of mine but he suddenly left and I could not reach him. The asst. service manager I spoke with that day could best be described as having a chip on his shoulder (overhearing his last interaction with a customer). In all fairness, I can't say if he was being provoked or not so I engaged him as if I didn't even hear the previous exchange.
I told him I was only trying to determine if the Sonata was due for an oil change (all service has been done there), and that during the last oil change the reminder sticker was filled out in pen instead of printed (as it always had been) and I couldn't read it. Every time I called it was a "receptionist" who answered and would only schedule an appointment. Twice I asked her to have a service department rep call me as I only needed to determine the mileage for the Sonata's next oil change. Twice I did NOT get to actually speak with a rep or a returned call.
Turns out the Sonata was not due for another 2000 miles.
Now here is where the Genesis comes into the picture
After determining the Sonata did NOT need an oil change, I asked about the possibility of an oil change for the Genesis (2015 5.0 Ultimate). I also mentioned the sunroof was prone to not closing smoothly and a minor upholstery issue on the passenger seat leather where it is covered with trim below the bolster. The rep asked me if I would be willing to wait for it to be done that morning. I told him yes, and the car was put in an already busy schedule for the service department. Overall, I was there three hours. That's a lot of time, but all three issues were addressed (oil change, sunroof, upholstery). I was given a 10% discount on the oil change, the sunroof was lubricated and I was encouraged to use it more often (which was good advice), and the upholstery issue was looked at to my satisfaction.
My understanding is that Lake Norman Hyundai is serving as the quasi-Genesis dealership until a dedicated one is up and running. What was obvious was that the Genesis line appears to get a level of priority above the norm. Now I don't know about valet service (actually not too keen on that anyway), but, so far, I'm finding the Genesis purchase has some built-in perks from Hyundai USA.
