Whistle sound coming from engine compartment under light acceleration (1 Viewer)

Definitely not present or audible in my car at any speed.

Your video seems to show the pitch increasing as speed rises, which is likely a mechanical, but not engine problem.

This noise is extremely irritating . Once you tune into it it can’t be unheard. I’d have to go back to the dealer to see if others make the same

Here is the sound . The great people of Lexus say it is normal

Thank you. That’s it. It tends to fade in and out like that too.

the fact that some of you are hearing it probably means that it’s in all trucks and we might have better selective hearing than the rest of. But the question remains as to the root cause

Certain I’m hearing the same. Light throttle at any speed, to me sounds more like something metal spinning smoothly at high speed…idk. Will try to get some sound clips tomorrow.
