For my 2023 Telluride EX. The road noise is worsened with my OEM Pirelli Scorpion Zero tires, looking forward to switching those out. What I'm talking about is road noise at highway speeds. It's more noticeable above about 60 mph and varies a lot based on the texture of the highway. Even over the quietest texture, it's still too much for me.

I pulled up the front carpet a little, near front foot well, and there's a lot of thick padding and extra sound absorbing material, but I only got a tiny peek here. My hunch is that most of the noise is coming from the back of car.
In the rear, there's some sound treatment under the rear cargo storage area. You'll see what looks like factory CLD, though it's very brittle and stiff. I can't imagine it's really doing anything. Attached to the carpet, is a combination of closed cell foam and sound absorbing material. I started tapping around this central area, and it was exceptionally noisy. I don't think the factory CLD material is doing anything.
The other culprit, I believe, is the sides of the rear cargo area. I popped this little panel off on the driver's side. Wow, just open fender wells passing sound goodies all over the damn place. There is some sound absorption in some places, but nothing on top of this little panel. My first attempt will be treating the wheels from the outside.
I was able to see the floor carpet is in split into two sections - cargo to back of 2nd row, 2nd row to front footwell. The last picture shows the break in the middle, showing more of the marginal factory CLD. I was worried that the carpet might extend upwards behind the firewall, but all in all, it doesn't look too bad to pull the whole carpet to deal with proper sound treatment.
I haven't decided on anything just yet, looking at options and products. I might start with treating the wheel wells from the outside first, then replace tires, and/or go into the cabin. I'd like to avoid pulling the whole interior and installing CLD/CCF/Barrier.
Thanks for any ideas, comments, or inspiration.
