I have an annoying intermittent interior vibration that happens on coarse chip surfaces or very fine undulations - it does not happen on speed bumps or pot holes.
It's hard to tell where it's coming from but it seems like it is in the middle to the back of the cabin.
Has anyone experienced something similar & if so what have you done about it?
Any help would be greatly appreciated.
I have an 2019 sTouring AWD auto
