Hi,
I've had my MY for 3 weeks. The road noise is terrible - as soon as you hit any rough pavement it's annoyingly/painfully loud. It also "booms" over any bump. I was going to return the car but I was out of town on day 7. My current plan is to go back and report it as a lemon and hope it's something wrong with my car and it can be fixed or I can get a new one, but I haven't had time to do it yet.
For comparison, it's way louder than a Prius or Subaru Forester or any other normal car. Otherwise, I love the car, but this has been a major disappointment as I bought it largely for road trips and value a quiet comfortable car.
I do have some hope reading the comments that maybe mine is exceptionally loud, as there is no way any reasonable person used to decent cars, least of all luxury cars, would say "this isn't very bad." I'll report back when I get some feedback from Tesla but it may be awhile.
