Buzzing from below the charge port area

[TestPilot]

Hey,

Does anyone else’s Model 3 make this noise? It seems to be happening only recently in the morning when HVAC comes on to warm the car. Mine is RHD so this is below the charge port.

the same thing happens to me while trying to charge at home.

Just got my TM3 2 days ago, I'm very worried about that noise, so I stopped charging it ...

Anyone else got info ?

The sound is getting louder and louder and is very noticeable.
Comes from below the left rear wheel, just like you. Same noise as well.

Mine has done that while charging. if I had to guess it’s mostly when the car/battery is cold? And it usually goes away after some time.

Well at least thanks to this forum I'm not heading to service center right away... But this noise is really loud and just does not sound right...

I'll let it run for an hour and see what gives... Hopefully the car does not burst into flames.

If that's "normal" I wonder if there's a word of warning in the manual ? Especially as most people here say charging is silent... Here with 7°C outside it's certainly not.

That's the rear motor cooling pump running to circulate heat from the motor to the battery pack. It will do this when charging, preheating the cabin or navigating to a Supercharger in cold weather. You will also hear a high pitch whine from the motor. Dual motor cars will make noises from both ends when the battery is actively being heated.

It's normal and nothing to worry about.

Thank you! I was worried as it can be really loud!
