Same thing happened to mine. I noticed it the day after I brought it home and took it to the dealership and he order the new tail lights and replaced no problem. Hope this solves the problem, maybe just a bad batch of plating on the tail light chrome.
Mine peeled as well. Noticed it the day after I bought it. Took it back to dealer and he replaced the tail lights, no problem. Hope it was just a bad run of plating and it doesn't happen again.
