I purchased a 2016 Trail Edition and as soon as I hit the highway to drive it home from the dealership, it vibrated between 50 - 60 mph and only between that range. Higher or lower speeds and the problem went away. I called dealer right away on my way home and was told to "give it some time..maybe tire has a flat spot in it".
Very aggravating to experience this on a brand new vehicle !
Since then I had another dealer install a 2" leveling kit

Well..since I altered the suspension I am on my own now. Dealer where I purchased it won't touch it now.
The vibration has not been any worse (3500 miles on it now) but very aggravating for sure!!
