Rocks Rolling Around In Ventilation System?

[BANKWUPT]

Hey guys, have an issue with my Sept 2018 Model S. It seems like rocks have gotten into the bottom ventilation system under the front seats, on both sides. They roll around when I go around corners, accelerate, or brake.

Here's where I think the rocks entered, very easy for them to go into here from passengers in the rear.

Here's a video of the noise it makes when I accelerate or brake, and it is on both sides of the car.

This is driving me crazy, I have searched for anyone else that has had this issue but can't find anything. Anyone have any ideas?

I had paintballs in my floor vents. They were very easy to get out.

After a hard acceleration, the rocks should move toward the back and at that time you can get them out with your fingers or a vacuum.

I could never make them reach the top portion of the vent again, 75D problems I guess? Maybe I need a performance model for that lol they were stuck pretty good down there.

I ended up getting this little snake camera that connects to my phone and stuck it down there. I saw rocks on both sides

I then ordered this 28" dryer cleaner vacuum attachment that is small and bendy and shoved it down there. Had to do it a few times but now the rocks and noises are gone! Woo-hoo! Hopefully this thread helps someone else too
