I know its a long shot but its a 21 350 AWD. I have removed everything from glovebox, center console...etc. So no loose anything that I can visually put an eye on.

We all know interior sounds can be the devil to track down. But has anybody else had such issue? Its not a squeak like rubbing parts together. Putting pressure on the NAV screen, glove box, center console in various areas has had no impact on the sound. It sounds like maybe a fastener has weakened over time and now allowing movement of something behind the dash.

Thought? Also any good manuals on pulling it apart? I have seen some for older model but maybe my Google Ninja skills are not up to snuff.

 

Hey man, funny you posted this as i also seem to have the same issue. I started having this sound too (rattling somewhat, beneath or around the center area where the nav mouse is maybe where its coming from). I recently did open the middle center console open for a cable for my dashcam, and could not find the source, then again i did not have it open while driving to see exactly where its coming from. One of these days ill do a deeper check. Also check up on some DiY cable installs and such, they would show you how to remove the middle piece, the center console and even the silver side panels next to the center piece, just use a curve plastic tool which helps and prevents scratches.

 

So just to crack everyone up I am a dinosaur. I still use them circle like thingys called "Compact Discs" commonly referred to as "CDs". Well as I was fumbling with buttons for media I somehow got the CD to spin up. Wait...that sound...that sound familiar. Eject my 72 Seasons. Wait a bit to run over irregular terrain. Hmmm, no noise. Went to a spot it ALWAYS make noise....yup; gone. Massive face palm! Guess how the CD is held on the spindle for rotation allows it to vibrate. Who knows...but my very annoying sound is GONE!
