2022 Genesis GV70 — buzzing noise only at one engine RPM — anyone dealt with this recently?

Write down what you already tried. A second data point from another 2022 Genesis GV70 owner helps more than a generic diagnosis. That's where I'd start. If it doesn't change the out-the-door or the repair estimate, it's noise. I'd sleep better after that step, even if it finds nothing. If this is nothing, great. I want that in data.

Don't overfit one forum story to your car. If it still isn't clear on the 2022 Genesis GV70, a specialist hour can be cheaper than another round of parts. That's where I'd start. If it doesn't change the out-the-door or the repair estimate, it's noise. If the story changes I'll post the new data.
