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 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.
