I have the Lexus ES 350 F sport 2021 and current mileage 52k. Lately I’ve been noticing while driving the car on the highway. The engine is making lots of rattling noise. This is my first Lexus. Not sure if this normal with Lexus 350 Engines. I have attached a video below. please take a look and advise.

After turning up the volume I hear two or three increasing decreasing approximately one second long noise pulses. It isn't a rattle sound more of a drone type sound something like you get driving at highway speeds and hit a patch of grooved pavement and the tires' tread rotation isn't quite parallel to the payment grooves.
You might want to check out the Toyota forums to see if you can find a video or audio recording of the "2021 model year Avalon, Highlander, and Camry vehicles equipped with UA80E or UA80F transmissions may exhibit a whine or grind noise from the transmission" that there's a Toyota T-SB-0008-21 -Whine or Grind Noise From the Transmission outstanding. (The TSB has references to example sounds but the addresses are invalid.)
All of this generation's ES 350 model types (including F Sport models) use the UA80E transmission but I'm not aware of any ES 350 UA80E transmissions having the same or similar symptoms as those used in the Toyota models.

thanks for sharing, I’ll check the Toyota forums. I have uploaded another video.

If found this https://www.toyotanation.com/threads.../post-14954097 which has 3 videos on the transmission noise. In the first two videos in that posting the whining sound is constant and in the third demonstrates the whining sound varies by accelerator input.
I freaked when I found this. My 2021 does have a mild whine but nothing so worrying. However, I do worry it could turn into something worse. Mine has only 5K.
Do these transmissions UA80E also get used in es250?

I downloaded it as a PDF. I don’t have the actual link. All content is visible in the images. You should be able to find it by the TSB number and title. If you want I can email you the PDF.
