The surface of the steering wheel of my 2013 Santa Fe is starting to peel away between the 10 and 12 o'clock positions. I had a similar experience with the previous wheel when the vehicle went in for its first service. At the time it was replaced. I do not pick at the surface, do not wear any jewellery such as a wedding ring, or leave the wheel exposed to sunlight as a sunshield is always used. I am a careful older driver and have always taken good care of my vehicles. Have you had any similar reports? I am due for another service now, so it will be interesting to see what the Hyundai reaction will be.
You will be getting a new wheel. I have contacted Hyundai Australia and the company admits it has some rare problems, perhaps caused by people's skin types, but is happy to replace any affected steering wheel after a running change to cars for Australia.
