Humming sound underneath driver side

[Frankejr74]

Has anyone had the issue of hearing a loud humming, vibrating sound coming from underneath the cab. It's happened to me at least 4 times since I've had the truck(July 2018)
The sound(humming,vibration) starts up when I've turned on the truck and gets louder the more I rev up the engine. I figured out that by turning off the engine for a few minutes and then restarting it the sound goes away and it won't come back for a long time. Like I said, it has only done it 4-5 times since July of 2018 but it is annoying not knowing what the heck it is.
Thanks in advance for any and all info.

I get something loud and buzzing but it’s from the air conditioning seat when it first turns on. Lasts about 10-15secs

I'd wager the Active Noise Cancellation is malfunctioning. There is a TSB to correct the issue
