Strange buzzing sound / “accessories” battery drain

[thequackenbush]

My lightning within the last week or so suddenly has a buzz sound, similar to a neon light, that I can hear

it happens regardless of whether it’s being charged, sitting idle, or driving. Often, but not always.

I also see a significant portion of my battery per drive is being allocated to “accessories.” I turn off pro power when not being used to maximize range. I don’t have anything else being used.

Anyone else running into this?

the attached video was a bit after driving sitting in my driveway. It was a warm sunny day.

Maybe pumps and battery cooling systems as described in this Link ?

I checked through that, but it's not the fan sound I've heard before- it's a definitive buzz.

Looking forward to a follow-up of what your local technician finds, those are not normal sounds IMHO.
