I'm curious...Do you guys use the holders daily with coffee mugs made of alum or porcelain? I never had an issue over the last 3yrs but started using an alum mug a few months ago and can now see markings where it will definitely begin to wear out and peel if I continue using.
I don't use any aluminum or plastic beverage cups. 99% of the time it is take out coffee in a cardboard cup. In my case it doesn't seem to be related to metal or moisture. Got it replaced under warranty as well.
I'm having the same problem with my 2011, this is such a stupid feature too i didn't need it covered in chrome , if they can't do it right why bother. Wish they would do a recall on this but you know they never will...
