Interference noise when opening doors

[Mr Sophistication]

I have a 2019 Tahoe with 3000 miles on it. Does anyone ever hear a noise when they enter into their vechicle? The best way to describe the sound is it's similar to the noise a radio makes when you have your cellphone really close to it. An interference type of noise. It's a brief buzzing and then it goes away. The noise started about a week ago, it's done it three times so far. Today it happened and I didn't have my phone on me. Is this normal? Anything to be concerned about?

Thanks for your suggestions.

Happened again today. I think it might have something to do with the USB stick that I leaved plugged it. The computer seems to glitch out on occasion. Sometimes I have to unplug the USB and put it back in for it to work again.

Any thoughts?

Do you still have the ding-ding-ding sound when the door is open and the key is in the ignition but engine is off?

Yes, I just tested it.

I'm going to try taking the USB out for a couple of weeks and see if the noise goes away.

Got a 19' but no noises like you describe, the doors open and close like my other cars

Do you have retractable running boards?

Sorry for the dely, I'm in Costa Rica.

Negative, it has stock plastic running boards. I have a stock LS.

Is it your air ride making noise?

I used to have occasional issues in my old 2016 Denali when leaving my I Pod plugged in to one of the USB ports in the counsel. I moved to the other port and it didn't do it anymore. My 2019 doesn't have this issue, so maybe random.
