SVXY - if you have locking wheel nuts check underneath the trunk board and see if the 4 (One from each wheel) from each wheel, didn’t get out of the package and are rolling around in the tire.
Speaking of noises, one time I had a noise in my front cabin that was vibrating or clicking to the driver’s side. This was in a Nissan many years ago. I took the car back and a “brilliant” employee, and I do mean that, found what it was. In the eye glass holder, my glasses were clicking and moving at times as they weren’t sitting in there solidly enough. I took them out and/or moved them around and it stopped! The vibrating sound was emanating from one location and ending up in another.
