I have about 4000 miles on my Model X in a month. Took a long trip and found the ride quality to be poor. I can feel every little bump and crack of the road surface and also cabin is not quite. It was really bad in Illinois, particularly in suburbs of Chicago, as their road are really bad, with lots of bumps on joints. I felt like driving in a Ford Explorer. Is it normal in Model X? Is there a setting, I am missing that? PS: My Lexus RX450h rides much quite and smoother than this Model X ?!?!?
