Hello I have a 2015 with same noise Your describing. I have done all the tweaks and no luck. Did you ever get yours resolved?Bump! Hey, Archer22 - did you ever figure out what was causing your noise? Was it the fuse-box cover inside the lower glove box? Something else?
I have a brand-new ‘19 and have a rattle under similar circumstances as you and can’t isolate. Already tweaked my skid plate, checked/tightened every front suspension and steering bolt, retorqued sway-bar bushing clamps, removed end-linksand yes, tightened antenna. No joy....
