So yesterday my wife drove the Y by herself for the first time and came back complaining about the boominess over any road imperfection (and in Minnesota pretty much every square inch of pavement that's over one winter old is cracked and potholed). On earlier drives as a passenger she said it didn't bother her, but now it is starting to get to her too.
I spent a good 45 minutes squeezed into the trunk last night adjusting the hatch stops with the paper technique, ensuring that all contact solidly, but so far nothing has helped much.
I haven't yet had a chance to get the tubing or PVC caps to try the rigid stops that @MY-Y advocates BUT I have one major cause for doubt, which is that just sitting in the trunk, tapping on the center of the glass of the rear hatch, I hear it ring out like a drum with that annoying low frequency boom. It seems like Tesla has just inadvertently designed to function like a drum tuned to that low pitch. So rigid stops, while they might prevent some hatch movement over bumps, seem like they are probably MORE likely to excite that "drum"...
We've decided to give the car a few more weeks (and I'll try out the rigid stops), but are prepared to sell. Carvana will give us slightly more than we paid for it to buy it from us right now, so that's reassuring.
