Was the engine running at the time?  
If so, then it could be an indicator of fuel pump problem.  
If the engine had been turned off for several hours, then it is likely that you heard the self-test that is run periodically by the evaporative emissions system.

My '16 buzzes. Pretty sure it is the PZEV gas tank vapor recovery system. Hard to hear exactly where it comes from.

I have a 2018 and it’s normal. I read about it somewhere in my manual.

You read the manual?  
Congratulations!  
You, I, and a few other regulars in this forum are probably among the few who actually do that.
