Hi there - new here to this forum. Recently got my 2020 Telluride EX and within 24 hours of having it noticed a loud rattle that comes from the rear passenger area when I go over bumpy roads (e.g. snow packed , gravel, lots of small potholes etc). The dealership determined that it was the exhaust system hitting the frame of the vehicle when going over bumps causing this. They tested another Telluride on their lot and the same thing happens. They are advising they opened a case with Tech line who after working to troubleshoot narrowed it down to the exhaust is hitting a specific clip. Tech line advised it has now been raised to corporate as a "design flaw" with regards to where the clip is placed (very close to the exhaust system) and they will look at a solution; but, who knows how long that will be. Has anyone else experience this?
