I have 2012 and have a Intermitted sound that sounds like I am dragging a branch or grinding in the steering. The rack and pinion has been replaced and the sound still is there, sometimes if I hit a small bump the sound is there and other times not a sound. The shocks are on the middle perch with 20inch rims. I looked at the fender liners but did not see an issue. The sound is very loud when it happens but when I try to make the sound happen I can not. Very frustrating...
