Gen2 2020 exterior "droning noise" when running

[CTK59]

Just noticed this the other day. Hearing this noise which seem to be coming from the back end when truck is running. Attached video, the droning noise behind the exhaust note. Thought of what it may be?

I heard it, almost sounds electric?

Sounds like an '88 chevy truck fuel pump in the gas tank.

My ‘20 has sounded like that since new, I only notice it if I’m in the bed with the truck running. It’s the fuel pump.

Thanks... similar, never heard it on remote startup going to vehicle. After running and going to truck bed it very obvious.

Is it loud enough to hear inside the cab? May be one of your rear shocks. My coworker dealt with this issue recently, could feel the shock vibrating and it was loud enough to hear in the cab.

No vibration or sound in cab - just outside.

Shock itself would be where you can feel the vibration, if it is fairly loud outside the truck I'd check it out.

Live valve solenoid. Pretty common issue. Cheap part bolted to the shock to control the valving, warranty will cover.
