I took my 2011 DTS to Coulter Cadillac in Tempe AZ because the chrome is peeling off 2 wheels. I took a printout from a thread on this forum that indicated several people had this problem. Their dealers replaced the peeling rims. Coulter told me that I had caused the problem by running into things. I told them I hadn't run into anything. They said to "come back tomorrow and see the Service Manager. I asked them to read the printout I had brought about the peeling problem. They just handed it back without reading it and just blew me off. The WORST customer service I have ever had.
