Has anyone had issues with the leather on the steering wheel cracking? Suddenly, (and I do mean out of the blue in the last two weeks) there are a series of small cracks in the outer edge of my steering wheel leather, at the 12 and 6 O-Clock positions. I do not know why. Just very fine cracks, suddenly. Any input on what has caused this and what to do about it? I am a bit mystified.
