for what it's worth, I'm experiencing what I describe as "thrumming" at 30000km. A wheel/suspension person whom I believe knows his stuff said tyre wear on the inside and outside edges, all wheels, and showed it to me. As it was on both edges I had thought it was normal. I had an alignment done by him. Afterwards, the thrumming is worse but that is possibly going to continue until the tyres wear into a more correct pattern. I will report after more Kms.
After the alignment the lane-assist is much less active too, although the car tracked ok without lane-assist before.
