My '21 Platinum, built early Sept 2021, exhibits noticeable noises in the cabin on roadways with with tar strips, small repetitive bumps and cut groves for water runoff. I have 7k miles on mine and it's been like this since delivery. I've significantly reduced the noise by replacing the oem 21" wheels/tires with with 265/65 R18 Pirelli AS Plus 3 tires on aftermarket 18" wheels. The noise is still there just not as loud. I've also notice much less noise when the temp hit 90 recently. The noise increases as the temps dip below 70. I suspect there is a tremendous amount of road noise being transmitted via the front and rear suspension to the cabin in the Platinum model and the larger tire sidewall on the 18" wheels/tires and warmer temperatures help reduce it. Why the Platinum models exhibit this is a mystery to my dealership too. I've learned to live with it and often drive with the sunroof vented to help mask the noise. BTW, we are in the same locale. Go Bills!
