I get one really annoying rattle when I go over any sort of bumpy roads. Like shitty patched up roads. I can't tell where it's coming from exactly, I just know it's on the drivers side. If you know what a window that's lose in it's track sounds like, that is exactly what my rattle sounds like and it is LOUD. I can't figure it out for the life of me. I don't think it's the fuel lines, because the rattle only happens when I hit bumpy roads. It's not anything on the dash that I can see, and believe me I've tried touching pretty much everything there is to touch on the dash trying to see if I could find the rattle. Nothing.
Sounds like it's in the door, towards the front of the car. At first I truly thought it was a window rattle, but it feels tight and secure. Sometimes it sounds like it's coming from outside the car and then sometimes it sounds like it's coming from inside. I'm truly stumped. I'm going to the dealer in a couple days and taking the service manager on a ride over some bumps. You cannot miss the rattle. It's that loud. Even with the radio up at moderate volumes, you can hear it. Really annoying.
