I have a '12 Overland and the rattle typically happens @ 1.5-1.6 rpm, speed can vary but usually within 58-65 mph. Not always, but there is a definite sweet spot in that range. The rattle initially started off as a low hum but now is more metallic. Though, it could be the metallic rattle is now drowning out the hum. In any event, I thought I read a user post that the glovebox for the 2013 was changed somewhat. Can anyone verify? I've taken the Jeep in but of course they were unable to duplicate. I have to take it back in on Monday for a the sunroof track replacement, another rattle but there is a service bulletin for it, and hope they deal with it at that time. Thanks.
