I jumped onto this thread, since my wife and son both complained about the low frequency pulsing, and the high frequency squeal.
We've now driven 1250 miles, and for whatever reason, we're not noticing the issues...unless we're on a particularly bad stretch of washboard concrete. I'm beginning to think the low frequency noise is from the tires (19" Conti ProContact RX), which are now fully broken in.
My acoustician/recording engineer that was thinking about buying a Tesla this summer, and was looking forward to riding in our Tesla, with analytical gear installed, is having health issues that have prevented him from following up. So, my input here will be limited.
