Why is the Tesla so loud when it's parked? Air conditioning?

    So I haven't driven my Tesla in 4-5 hours and it is sitting in my driveway. I happened to open the door and I can hear that it is making a loud noise. I think it's the air conditioning....

    1) why is it so loud
    2) Is this because I have the air conditioning in some sort of auto mode even though I'm not near the car, nor my phone is not near it?

    If you have the climate system in Auto mode; then anytime you open the door the vehicle "starts" and the climate system starts up too.

    As far as the noise; that's just the electric compressor and electric fan -- noises you wouldn't hear if the car was an ICE vehicle as the engine noise would be louder than the climate system.

    If your climate system is on without either opening the doors or starting it remotely from app - then perhaps a visit to the Service Center is in order.

    Air conditioning from other ICE cars is also loud, just that you never heard when you are outside of those cars because they do not have the pre-conditioning feature. Tesla may be a tad louder ....

    Also battery cooling on warm days when parked. Can be quite loud. Same as on Model S.

    A pain ... but one of the reasons that degradation is so minimal!

    SO i just walked outside to my car again...It's making a loud noise like something blowing. I haven't even driven it today. I went inside, the air conditioning wasn't on...then the loud noise stopped... Can someone tell me what this is?

    It's about 80, but it's full sun and inside the car it says its 92.

    It's not that it makes a slight whirly fan sound...rather, it's really loud like you can hear it 50 feet away

    Mine has never done that but I assume it’s a cooling fan of some sort.

    Funny thing is that I haven't driven it today at it's 12:30pm I've been at home all day. The car is just sitting in the driveway in the sun.

    Mine is really quiet, even when I cool down the car. You might want to have that checked.

    Ya. pretty dumb. Basically, car has been sitting outside and NOT driven at all today and it has this fan blowing really loudly. So loud that the neighbors can hear it and asked why my car has been on so long.

    Maybe its the computing/control unit fans. Per P111 and P116 of the manual:

    This sounds like the battery cooling fan (which can be pretty loud).

    Do you have a dark colored Tesla? If so, how hot is the hood? If it's hot to the touch, that may explain the battery cooling.

    Yes. I have the metallic black. And it is hot to the touch...Are you saying all Tesla's are that loud in the sun. It hasn't been driven today. Just sitting outside.

    I am going to assume that you already disabled cabin overheat protection (if not, do that now under Controls > Safety & Security). This is the option that keeps the inside of the car below a certain temperature after you exit.

    I suspect it is the combination of both of the following: (a) the car is running tests or recharging the 12V battery and (b) you have a metallic black car that is sitting out in the sun in 80 degree weather. Normally, battery cooling shouldn't be necessary when running the tests or recharging the 12V battery, but you have a black car sitting out in the sun. If you had a white or silver Model 3, or your car was sitting in the shade, I doubt the fan would be on. The fan should turn off when the Tesla finishes whatever it is doing.

    Edit: Also, if you installed third-party apps for your Tesla, get rid of them.

    I read this post. ...the funny thing is that you can't go hiking or camping for a couple of days on a full charge because your battery can run out if it's a little hot out there and your batter fan stays on? Seems kinda odd to me. Anyways, those posts were from a couple of months ago. You don't think have fixed it by now with a firmware and others would notice the same.

    Tesla has greatly reduced battery drain with recent software updates.

    Ok. So here is the deal. They said it's the condenser fan is being overly active when it shouldn't with the temperature.

    I'm surprised others haven't experienced it.

    Anyways, they said there will be a firmware upgrade in the middle of September
