When my car gets up to 60mph or more there is a buzzing sound. If you slow down to 55 it is not there. Sounds like it comes from the dash or directly above the rear view mirror? I have never had this type of problem and I am lost.

Raise car, put on stands. Grasp tire and push/pull both horizontally and vertically, if any movement then possible wheel bearing, ball joint, tie rod, control arm bushing.

Check CV boots for any signs of leakage or cuts/rips in rubber boot.

While the sound is coming from inside, it may be a problem as described above or an alignment issue that is causing the buzzing inside.

Does car have power moon roof?

Found that the weatherstripping at the top of the windshield had loosened. We reapplied Weathestrip adhesive and fixed it. Thanks
