Rubberbumper

I'm jumping in here because my E400 long roof has 19" AMG wheels and figured I might get a better audience. This is now a 3.5 year old car and I've found the metallic paint on 3 of the 4 wheels is starting to peel. I'm wondering if anyone else has run into this? Photots attached.


Will be heading to the dealer to make this a warranty issue, but, anticipating pushback, it would be nice to know if this is a problem others have had. Thanks in anticipation.
