It seems to come from behind the glove box. Wondering if anyone else has experienced this and if they figured out what it was?

Ive never owned a hyundai but my previous experience with honda/acura I do know the glove box can be pulled out and there is a cabin air filter behind it - perhaps it is the same with your hyundai - check your manual and see if it comes out and maybe you'll be able see whats rattling behind it...even if there is no air filter behind it I am sure it comes out...
