Hi everyone!

I am new to this forum but, I thought y'all might be able to help me with something I noticed with my car (2021 NX300). So far I love the car but, I've noticed that when I get the car up to around 1000-1250RPMs. It makes this noticeable low frequency sound, sort of like a low frequency hum. However, once you get past it, the sound goes away. I looked around some forums and there is another post that talks about it: https://www.clublexus.com/forums/nx-...-1300-rpm.html but, there was no much info there.

I have brought this up with my dealer and the mechanic who looked over the car actually came out to speak with me about it. He essentially told me that it's a resonance from the car and it usually sounds like that. He said once the car is really broken into, it could get louder because the car is able to be running at its fullest. The sound seems like it's under the car but, it's a bit hard to tell so open to other ideas on where this sound could come from.

I bought my car new and right now it has ~14150 miles.

I would love to know if any of you experience this? If so, did you guys fix it? And how? Is this something I should be concerned about? What could be causing this?

After couple days sound is still there and sometimes getting so loud and if I drive fast in the highway is better but on the city is bad so bad where you can’t drive fast and kept engine on higher RPM
