God...this was pissing me off, so is I decided to pull down the headliner at the back and investigate where these noises could be coming from.

The main culprit is the piece of plastic that comes back with the sunroof itself, it runs from left to right, the full width of the sunroof.

While I was driving I could usually put my hand back on the roof liner and stop it from rattling when the roof was open.

I simply installed a strip of 1/4' thick x 3/4" wide self adhesive sponge rubber tape alone the full length of this plastic channel.

I also double up a piece right in the middle of this channel as it hangs down the lowest at that point.

Also when you look at where the sunrrof comes all the way back you will notice how two pieces of plastic can come in contact with the steel roof so I put a couple of felt pads on the steel roof section.

I also installed small self adhesive felt pads about the size of a dime at each of the pionts where the rear part of the headline clips into the metal channels.

All of these simple fixes mean my sunroof does not rattle at all, I tested it up to 125 MPH...not that you can hear much at that speed anyway.... : )


Also fixed a slight clicking noise in the drivers side door panel by pryed open the door panel where the door lock is and put in some more the of the foam tape.....fixed!

Hope this helps others with this annoying problem.

Cheers,

Ben

 

Good info. I just had the sunroof motor replaced. Toast after 25K miles. While is was apart, the dealer put in rattle insulation.
