SALTY2

Hello All

I've been having rattling noise problem on my 2010 RX350 for months now. It comes from the passenger side corner of the sunroof. It sounds like metal hitting glass. I took it to the dealer twice already but the problem is that each time the noise stops. I even drove with a technician in the car to replicate the noise but each time no sound, nothing. Has anyone have the same problem? or know if there is a bulletin in this regard.
Any help will be greatly appreciated

If the sound goes away each time the tech rides with you, is it possible that the sound is actually coming from the passenger seat, and that when weight is on the seat, the rattle goes away? Just a thought...

Check the roof handle.

good thinking, but no, it happens when someone is in the passenger sit as well

I don't know what you mean by roof handle. Do you mean the bar that puts upward pressure on the glass?

thanks, but the noise that I hear is from the sunroof area next to my right ear and from the passenger side edge of the sunroof. It clearly sounds like metal tapping on glass. I have a friend who owns a Venza and his car makes the exact sound as well!

my GS430 had the sunroof noise for years, dealer had various attempts at fixing it... but it always come back after roughly a week. I even had a brand new sunroof installed.

I think once you have it, it will never go away.

my friends RX350 has the same issue, with no luck at fixing it.

My 2009 RX 350 also has a rattling sunroof. It's loud and annoying and happens when I hit a little bump......
Does anyone have a fix?

I have 2 issues with my sunroof;
Firstly, I also do have the metal noise as mentioned in the OP but mine was more evident when the roof was at "slanted" angle. Took it back to the dealer and they applied some grease and the noise seems to have gone away or at least fainted to a level that doesn't bother me anymore.
Secondly, I also have noise coming from the sunroof visor (don't know proper name). This time is more of a plastic tapping noise when travelling over bumpy roads. Also asked the dealer to check out and they must have applied some double sided tape or something because the noise comes back every now and then and i just push the visor upwards and the noise goes away so the tape must have come loose. So i have to take this back again for them to take another look. Not too happy with this problem.

I have heard a similar noise Salty. In my case it was coming from the black piece that runs the length of the sunroof in the front and raises when the sunroof is open. I heard it also when I would slam the door hard so finally I was feeling around while slamming the door and if you touch that piece it would stop. I put tape on the right side of it where there is a seam and it went away. Try this and let us know.

Check the bolts that hold the glass to the sliders on each side. Seen some loosen up over time. Just a thought.
