I contacted Hyundai America via Contact Us on the myHundai site, about my 2015 Genesis Sedan Ultimate 3.8L, and this is the response I got. Seems like they are saying, Some Hankook not All are to be replaced, and I will receive a letter IF my Genesis is affected!
Thank you for contacting the Genesis Customer Care Center. Your satisfaction is our priority and we appreciate that you took the time to contact us regarding any open recalls or campaigns for your 2015 Genesis.
Hyundai is aware of a small number of customers comments regarding the factory installed tires on the 2015 Genesis. Specifically, Some customers have mentioned slight tire noise and vibration which may be amplified by road conditions. As a result, we have changed the Hankook Noble2 factory installed tires to 19-inch Continental ProContact tires (5.0L) or 18-inch Michelin Primacy MXM4 (3.8L).
As this information regarding the Hankook tires is new, this information is in the process of being updated as more information is available. You will receive a letter by first class mail if you Genesis is affected. The letter will have more information and instructions on making an appointment with your dealer.
Your Hyundai dealership is an excellent service provider to protect your investment. Servicing your vehicle at your local Hyundai dealership ensures that your Genesis will be repaired by factory trained Hyundai technicians with specialized diagnostic equipment who use only Genuine Hyundai Parts and Accessories.
