I hear a similar noise in my rx 350 2007. Did you discover the problem?

@Did you solve your problem. I hear a similiar noise in my rx 350 2007

I have a 2008 RX350 and sometimes I hear a very annoying buzzing sound (kind of sounds like a thin metal on metal vibration noise) coming from the passenger side. It sounds like it is coming from the panel between the front passenger door and the back passenger door where the seat beat comes out of. It is intermittent, but is especially noticeable when driving on the highway and/or driving over road that is a little rough. We heard it almost the entire way back from Florida to Texas. Has anyone had this issue and resolved it??

I would love to have an idea of what it might be before I take it in. As you know, you can never get it to make that sound when you take it in and try to show them!

Thanks for any help!

I am sure you have first checked for lose items under the seats.

What I would do is try to pin down exactly where the noise may be coming from. Move the front passenger seat all the way forward and sit in the back seat. When the noise starts, bend down and check for the noise pressing in on suspecious areas. Also, try lowering the passenger window during the noise...Hope this helps...

I don't know if this helps... I have a 2009RX350. When there is no passenger, the seat belt retracts but the belt (and the bukle) don't lie 'flat' agains tthe passenger seat or the side post. The slight twist means that the buckle 'rattles' against the pst. If you were to pull the seatbelt 'out' a few times and check that it is in the correct position when it retracts, you might eliminate the noise.[i have to do it each time I have had a passenger because - probably due to the seat/back/seatbelt height positions - the seatbelt never retracts in such way that the belt and buckle are 'flat]. Good luck! -- An easy way of testing would be to anchor ('buckle') the buckle and see whether the noise stops.
