Looking for help from folks with this rattle. I have had the car two weeks and only have 300 miles. When going over any road that is not glass smooth I get this crazy dash rattle that seems to come from the drivers side dash top. If you put your hand on it the rattle moves to the sides. Its driving me mad. Any suggestions ? I know its only an Elantra but with only 300 miles surely it shouldn't be rattling this bad already
