Default Rattling inside over uneven/bumpy road

Thanks in advance everyone.

I have been trying to find the source of the noise for almost a week now and it’s driving me bananas. I think it just got lightly louder today.

On Labor Day, I was driving out of NYC and there were two raised wide metal humps on the highway. Didn’t have a choice and had to drive over at highway speed. Felt like my car got punched.

A day later, I noticed a faint rattling noise from the inside when I was in a parking garage where the ground has lumps.

Today the noise got louder, different area so not sure how much of it being louder had to do with the location /bumpiness and how much to do with more time having passed.

Im not positive 200% if it’s because of those raised metal humps, but anyone got any idea?

I booked an appointment next week.

Video is short because of file size restraints..Thanks in advance!

Some loose item in your glove compartment, center console, or trunk?

I think it was the passenger buckle that was bouncing around...pushed it back and i think it's fine now. But there's some noise in/around the passenger door as well. I took it in and the technician tends to think so...but I'm not going to have them take it apart yet...maybe when/if the noise gets louder...original manufacture assembly is always better/tighter, i think. So that's my update!

Try pushing up on the sunroof, the gasket shrink and causes vibration. Play a heavy bass song and see if you can pinpoint the source. Good luck

I'd do a through inspection of the suspension and test drive both with windows up and down to replicate the sound before taking it in.
If the sound is intermittent, I would make sure I can replicate the sound near the dealership so the tech hears it when he's with you instead of getting the car back as "could not replicate customers concerns".

Hope that helps.
