Engine chirping / rubbing sound

[demarche]

Curious if anyone has any insight into what this sound originating from my engine might be.
Its a chirping or rubbing sound obvious at idle, regardless of AC on / off.
I first noticed it during a long roadtrip in hot weather, and it has persisted since.

Issue is currently under investigation with Toyota, TAS case number TA250480154.

This is on a 2024 off-road manual transmission.

The dealer seemed to suggest I was not the only one experiencing this issue.

Please see attached video for a clip of the sound.

Mechanic @ lexus dealership identified this sound as coming from the solenoid in the purge valve, have to try to get a Toyota dealer to replace now.

Is that diagnosis from a an in-person diagnosis or a lexus tech commenting on another forum?
Verify with stethoscope, or unplug it & verify noise is gone...

I stood with the lexus mechanic in front my engine while they used a stethoscope and manually unplugged & plugged back in the purge valve.

As a bandaid they actually sprayed some wd-40 in the valve which seemed to help somehwat.

Any update on this? I'm been having the same chirping issue on my 4Runner since it was new, definitely not the AC issue but the one that might be the purge solenoid. Curious if anyone has replaced this and seen any improvement? For $90 I'm tempted to order one and just try it, the chirping has ruined the new car experience for me and my dealer has been zero help.
