Unhappy 2020 RX F-Sport Intermittent Rattle

Hi!
I recently purchased a 2020 Lexus RX350. When I test drove it and drove it for the first week it was quite. I went over a bumpy road earlier this week, and it sounded like a pebble or something in the car became loose and now I get this intermittent rattling sound by the passenger side window which occurs even over flat pavement. Had a mechanic drive with me and of course it made no rattle noise when he was with me. This sound has happened twice with one of those times being the first time I heard it within the past week. It lasts for a up to a few minutes then can be quite for a few days.



Do you have any ideas as to what could be causing this?

Sounds similar to mines.

i think the noise is coming from the rear slider in the back.

Really? Was it also intermittent for you? I am guessing you had it repaired under warranty?
