I just bought a new Touring-L. Very pleased but I ran into an unusual problem. I kept hearing this metal on metal sound which seemed like it was coming from the sliding door somewhere - it was driving me nuts. I was considering bringing it back to the dealer to find the rattle. What really confused me was the fact I didn't hear it all the time. I finally found the problem. There was a big screw rolling around in the sliding door deck stuck in a corner and out of sight. So every time the screw rolled the "rattle" surfaced. I can't find where the screw came from. Glad I solved that!
Interesting. I may have the same rattle sound as you and perhaps mine is in the passenger door. It is hard to pinpoint while driving as I asked my wife sitting in the passenger seat if she hears it. She thinks I am crazy. I leaned towards the center while it was rattling, and the rattle sound went away. I learned back to the drivers seat, and the rattle was audible again. Maybe it is coming from the sliding door?
Anyhow, sounds like a baby rattle. I also noticed a rolling sound when I turned a sharp turn, and the rattle went away. It comes and goes.
My Mazda cx-9 with 55,000 miles on it that I traded in for this van never rattled. Not even a creak. This has 400 miles on it and rattles. I also noticed a creak in the drivers and passenger side window pillars as it flexes. Sometimes, I can hear the wiring move around on the passenger side pillar.
I hate to bring it in to get this fixed but I know it won't go away. I bought that extended warrant thing too... so do I have to pay the $100 deposit?
