Continuous high pitch "whistling"/"whirring" noise when charging or when "woken up"

[GooseSlapper]

Recently purchased a 2023 Model 3 RWD. All is well, except when the unit is charging or "woken up" (door open, trunk open etc) there is a high pitch whirring/whistling noise coming from the front part of the vehicle. It's fairly faint, though clearly heard in a quiet garage. Is this normal? The Chevy Bolt sitting right next to it is dead quiet when charging. It almost sounds like a bit of inverter whine, but I can't put my finger on it. I can't sort out how to embed an audio file with this post so here's dropbox link to .wav file recording. Desktop.wav. Thoughts?

Hard to tell from the clip but could it be the AC? Does it go away when you turn the AC off?

Noise keeps going even though AC is off. As long as the car is charging -or- sentry mode is on or otherwise "awake", the noise is made. I'm curious to know from other Model 3 RWD owners if their cars are dead quiet when charging in the quiet garage or whether they too, also here a similar (low level) noise.

As soon as the car is awake, it will run the coolant pumps. The speed of those pumps is variable.

Thanks GtiMart, so when yours is "awake" (understanding there's various levels to that), it's always making a faint noise?

Coolant pumps running. There are two.

Same noise here check it out - inside and outside of car recordings

That’s the noise! Reckon that’s just the noise a normal car makes when awake.

I have a high pitch intermittent squeeking noise (like a cricket) when my 2023 MYLR is preconditioning. I saw someone state on Redit it may be coming from a fan motor. I will have it checked by service soon. Anyone else have this issue?

 

[tommy5454]

Not an expert but I have learned that these noises are mostly normal and no reason for concern.

I understand but this is a squeak that sounds like a motor that has a bearing having an issue. It is not the normal sound/s and did not start doing this until just recently.

ya, i hear those when car is charging, I assume its the battery warmer doing it's thing or the interior fan heating the inside. It only lasts a few minutes or I just turn off the defrost heater manually.

Normal I assume.
