Just purchased a 2005 Xf convertable with 45000 miles on it and on the way home I noticed that when I turn either left or right slowly and tight I hear a clunking sound. I've never experienced that sound before and was wondering if they all do that? Bought it from a Chevy dealer and the service dept suggested I take it to a Dodge dealer to have them look at it. Will do that but am looking for a little insight.
