I hear this noise while turning to the right. As soon as i start turning i hear the noise, and if someone is sitting in the third row, they say that they can hear it right under them. I've taken it to the Gm dealer a few times and twice they say that they fixed the problem by tightening a couple of bolts, but it didn't fix the problem, next time i take it in I'm going to recommend that someone sit in the third row when they test drive it to see if they can get a better idea where exactly the sound is coming from.
