Continuous high pitched noise from the frunk

[frunktastic]

Hey everyone,
I'm a Model 3 (2021 version) owner since last week, I got it used from Tesla inventory. It's a really fun car to drive and I'm happy about it.

Anyway, I noticed that when the car is parked and in deep sleep, there's a continuous high pitched noise coming from the frunk. It's very low in volume but I can definitely hear it in the silence of my garage.
The worrying thing is that it doesn't stop. I've checked many times at every possible hour in the past 3 days and the car is never silent.
I've recorded it with the iphone so the quality is not great but I tried to isolate it and its frequency seems to be around 3000 Hz.
These are the recordings if you want to check them out.

Do you think it's something worth to report to Tesla service?

could be the heat pump

Sounds like crickets and cicadas mixed together. Seriously though, mine makes lots of clunks and whirring noises like relays and fans, but I haven't heard that before.

I have to say that I have never heard such a sound in my 2020 M3

I've had a 2019 model 3 without a heat pump, and a 2023 with a heat pump, and neither of them make any noise when they are in deep sleep.

Any update on this issue? I just took delivery of a 2023 MY and it makes this same noise non-stop.

Final answer from service was: it's all normal, the system keeps the battery in a certain temperature range. I got used to it and don't notice it anymore. Sometimes is so faint that I hear it only at night going very close to the frunk.
