26 OT + and I have had the "clunking" noise since day 1 (2 months, 3K/miles). I didn't realize it at pick up, just drove it out of the nice smooth parking lot onto the highway (purchased in NC and drove it home to NH). At first I chalked it up to lack of knowledge on E-KDSS suspension, but now I'm certain something isn't right. From reading on this site and others, I'm guessing it's sway bar links and going to have dealer look at it when I bring it in for my first oil service in 2-3 weeks which will put me at right about 5K/miles.
