2017 Chevy suburban Buzzing noise coming from engine

[Abdullah576]

Hello have a 2017 chevy suburban I hear a buzzing sound sometimes when starting the car. I’m positive it’s not anything to do with the radio or anything as I hear it very clear when I open my car door it sounds like it’s coming from the engine or near the wheel well. But it’s definitely not the electronics anyone know what this could be?

It goes away when I slightly press the accelerator.

Maybe an exhaust or other kind of shield underneath, vibrating at idle. Record it and put in on a hosting site (YouTube, etc.) and post the link to it in this thread. Then we might have other suggestions after hearing it.

Is the truck running when you hear this, or just when you open the door?
