When I open my driver door in my 2017 Tahoe LT, I get some type of mechanical noise that lasts for about 2 or 3 seconds that sounds like it's coming from under the running board towards the rear. It only happens after I unlock the vehicle and open the door. Not during any subsequent reopens. Sounds almost like an HID headlight transformer (which I don't have) becuase I hear a similar sound in my Honda Odyssey. Any thoughts?

Yeah I get the same thing, open door, weird clicking sound. I figure it's either the fuel pump clicking on to prime up the system before startup, or like you mentioned, the HID's kicking on.

I don't have an answer but do share the same question. I've had my 17 LT for 3 months now and have been wondering what it might be. My first thought was the memory seats adjusting but I've confirmed that isn't what it is.

I have that sound too. I thought it was the shocks (I have max towing)
Charging up. Leveling if you will

The compression comes on after you start it.
The sound when you open the door is the fuel pump. My BMW does it too only louder and longer.
It's a new feature for the 2017 Silverado so I'm assuming that's when the SUVs got it too since that's when they got active grill shutters.

Because it figure if you open the door it will be soon so it's priming the fuel rail. There's a lot of stuff running when the car is not running. Tests are being performed all the time.
you will see your mileage pop up on the lcd screen also when you open the door
