This is a problem all across the industry. Goes from low end class C’s to high end DP’s starting back in the late 2000’s. From what I’m seeing it’s from your body sweat and the oils from your skin. My 2012 I found the sofa this year starting to crack. I had ordered a reclining loveseat from Laz Boy before I ever found the damage. And now I’m seeing the euro recliner where your head rests is starting to peel. My driver and passenger seats are still in good shape. When the time comes I’ll end up having the seats reupholstered with real leather.
