I have a vibration which is quite high pitch almost a like a hissing when I really step on it. Usually if the rpm goes above 3000. In normal acceleration I don't hear it. It almost sound like the kind of noise I had before with another vehicle that had a loose heat shield. My RX330 presumably was not involve in the manifold recall. The mechanic from the dealer was not able to pick it up and therfore no fix.
Please keep us update.

could be your multi-panel moonroof. I had a mystery wind noise from my rear passenger C pillar - it seems to have gone away after 3K miles... I also like my stereo loud so that's a good fix too

This noise is coming from the dash or the engine compartement and the noise comes on only when the engine is under load. The multipanel moonroof rattle is another story.

See post https://www.clublexus.com/forums/sho...hreadid=92864. The tech at the dealer indicated that several cars have come in with the vibration/noise on acceleration. He spent two weeks trouble shooting the problem on one vehicle with lexus engineering but was unable to find the problem without taking the car apart. He did identify a problem with the speedometer housing that is causing some of the noise (retainer clips) and he fixed that problem. It is quieter but the source of the problem has not been remedied. I will let you know if I find out more.
