Hi I have a 2020 Telluride I started noticing a clunk sound at the rear of my vehicle. I take it to the dealership and so far they changed the sway bar bushings. They told me my cross member was lose. I keep wondering how this is a new car. Now am waiting for the rear shocks to see if that fix the clunking. This happened any time the car body flex . Anyone else notice this clunk in there's..
