50 - 70 MPH Vibration
How many of you experienced the vibration at highway speeds? I googled it and it’s a thing on some 2015 and newer models. It’s not violent but it is noticeable in the shifter, floor, seat, and steering wheel.

I agree. The dealer already swapped tires and wheels with another smooth riding GT and my car still had the issue. They are purchasing a new vibration analyzer. When it’s in they are going to hook it up to pinpoint the issue.

I had this issue twice. It is a level 4 vibration that is coming out of the rear differential. The first time, they replaced the drive shaft, gutted and replaced all the parts in the rear diff after they found a 0.004" variance in the ring gear. The problem came back again less than a year later. This time they replaced the entire rear diff to include the case. Been almost a year and it has not come back. I knew it was a Diff issue as the backlash in the rear end was getting worst as time went on.
