I have a 2012 Tundra. I’ve noticed it has almost a “drum cadence” to it especially when she’s idle. It’s a low bass drum sound. When I turn it off I still hear it for about 5-6 seconds then it stops. I can hear it in the truck but not outside of it.
can you upload a video of it to Youtube?

The key clue I think is that it keeps going for a few seconds. That would tend to make me check the fuel pump and evap system - either could make noise after engine stop.
