I was in for an oil change a couple weeks ago and I asked the service advisor to take a look at my steering
wheel as it is not holding up well (see post above from April 30th). After review, the dealership/Hyundai decided to replace the steering
wheel under warranty. Very nice of them. The leather on the replacement is super nice, and it feels like the leather they are using on the G80 these days ... not as smooth as the leather that came on the 2016. The replacement steering
wheel leather has a bit of "texture" if you will. The brown color on the replacement steering
wheel aligns nicely with the brown leather above the gauges. Per the dealers paperwork, the total cost for the work was $880 (including the $60 Enterprise they put me in). I have a copy of the changes, posted here is the warranty invoice along with a couple images (including an old and new close up).
As an aside, I am not sure whey this happens, I seem to get XM Data from time-to-time. I am pretty sure I only have the music package, but sometime Weather and etc. services appear. Not sure if this is related to being at the Dealer, I just happened to noticed this after I picked the car up and was testing EVERYTHING out that I could before I left the dealership ... just to make sure all the steering
wheel controls/features worked as designed.
