Re: sunroof deflector
Not yet, but I'm tempted to. At interstate speeds it begins to make an awful buzzing noise. I thought of resealing it, but not sure if it is the seal, or the integrity of the plastic itself.

Any suggestions on how to fix this problem? Is there a TSB for it, I couldn't seem to find one.

Every car with a sunroof that we have ever had (maybe 9) is the same way. Without a deflector they all had that rumble unless you put a window down a little bit. Seems to be more an air pressure thing than anything. i don't really think its a design or equipment flaw.

I agree...has to do with wind passing over the opening. I am sure an engineer could explain why it does it....easy fix...crack open a window.
