RX350 Engine Sound (Noise)

I just leased a 2019 RX350 Luxury (Not F Sport). I found the engine sound is noticeable when the engine after 1500RPM. I am not sure if the sound is normal. It looks like a similar droning type of noise at 1500 RPM. And the sound is fine after 2000 RPM.
However, I think it is normal when I drove at highway.

I found a video from YouTuBe about drone noise in 2016 model. I don't think my vehicle has the same drone noise.

I checked with the sale and he said it is normal. Should I check with service department?

what does a sales guy know about car mechanical tissue ?

take it back to dealer and have a mechanic or shop foreman to go for a ride with you to point out your concern

Thanks, Do you think I can do during the first service (at 1600Km), or book an appointment with the dealership as soon as possible?

if the noise does not bother you much, then you can have the dealer look at it during 1st service.

Thanks, If I have the time I will have the dealer look. Because I only notice the noise when I turn off all music. If I turn on the music, the noise is not noticeable easily.

Is it fake engine noise pumped in from the speakers?

Nothing odd from that perspective with the wife's 2018 RX350.
From what I read, it's a low drone type sound and either related to the exhaust or something funky going on with the tranny.
You may simply need to drive a few thousand kilometer to break in the vehicle.

How can I determine if the noise is from speaker or engine?

Does your car also make a “ticking” noise from the engine compartment when it is idling (not moving)?

If I open the engine hood, I can hear some "ticking" noise. But I check online, they said it is a normal sound because direct injection. I book an appointment with service department next week to check that.

I check the thread. I don't think my engine's drone sound is same as their vehicle. I book an appointment next week and check with dealership.

How about, it could be wheel bearing noise?

The noise is similar with this droning noise. But my vehicle only has this noise during accelerating and at 1500 RPM.

So early on a brand new delivery?
Bad bearing would sound like metal scraping.

This is from what I read, 2019 RX350 is very choosey in tire replacement. They say it has to be replaced in set. If you had tire replaced check the rotation of direction on tire. Check proper torque on lug nut and check tire pressure. If your bold, you might switch tires around if noise goes away. This probably has nothing to do with drone noise but just something to think about.

I don't think it is bearing noise. But it is a droning noise at low gear and 1500 RPM.

If you stay in gear 2 or 3 and maintain 1500rpm is the noise constant?
