Post a video on YouTube. I'm betting it's the age old tire manufacturer tire sticker rubbing against something in wheel well. If it is, it mostly goes away around 5,000 miles. Mine sounded like a metal ball bearing rattling around. If you travel fast enough the sound goes away. It's noticeable at low speeds and perfectly coincides with the wheel's rotation speed. Others have confirmed it's the sound a sticker on the wheel slapping against something until it gets shredded enough. Search model Y forum for wheel noise or sticker. I'll try to find the other thread...well the most recent one.
I went to SC about it...on test drive they heard it....then in garage they could not, because they are not driving the car. As I left the SC, driving slowly down their driveway...the car made the same noise. The next weekend I took a long road trip where I took the opportunity to REALLY punch the performance model Y on an empty highway....after that trip the noise mostly went away. I hear it every now and then but the noise level has decreased by an insane 1000% ...it would be hard for me to get a service tech to hear iron a test drive.
