New to this forum. I have a 2020 (bought new) with the tow package and auto level system. Several months ago noticed rattle in rear and very stiff ride. Brought to dealer and noise was minimized but was told ride was normal. Had to go back a second time and again told ride was normal. No way. I am bouncing on highway use. Does anyone else have this issue ?? And what was your recourse. Cant drive like this. Thanx in advance.
