I have this same issue on a brand new 2024 Touring. Sounds like the woofer is bottoming out. Nowhere near as bad as Bobby’s but annoying enough for me to get this fixed.
Went to Lowe’s and got the
butyl tape. Will update you all on how the fix goes, it seems relatively straightforward in my car. Kick panel comes off easily and I can see the tape that needs to be replaced. Did not need to take off the door seals or anything like that. I think this problem is far more pronounced on the driver side so only fixing that side for now.
