Under car rattle
Hi! I have some strange rattle sound that occurs at highway speeds. Here is a link to a similar issue with an avalon:

I hear the same noise and have a feeling it's the same thing on my 2020 UL350. Has anyone else encountered this? I took this to a local mechanic and they said everything was tight underneath; however, I'm not sure I trust their diagnosis.
Thanks!

I recall no reports here of undercarriage noise not attributable to something that got loose and was quickly tightened up.
Your report is a bit confusing to me, as you report that you "have a feeling" it's familiar to something on a previous vehicle, but you report that a mechanic who, I presume, got under the car and nosed around, found nothing loose. When your "feeling" contradicts the empirical findings of someone with training and experience in the field, the next step, I would think, would be to seek a second opinion from another expert.

There was a rear end rattle thread a year or so ago. Neither denise2019lexus350 or scubapr posted if they ever found a resolution to their rattling noise but in that thread's post #16 I posted a link to UltraLux22 post in another thread that had this fix Lexus service department entry:

Can you isolate if the rattle sound is from the front? Or the rear?
