    For the life of me I cant figure out this on/off with the door thing. To the point that I wonder if all my sensors are working properly? So, because it's 120 degrees in the car, I turn the AC on while walking to the car. Great. If the passenger gets in, the AC keeps going, until they shut the door. BOOM, car (and AC) turn off. Damn. Touch the screen, car and AC come back on. Rear occupant gets in, when they shut their door, BOOM, car turns off. Damn. Touch the screen, car and AC come back on. Driver finally gets in, when they shut the door, AC turns off, but car stays on and AC restart automatically! So, I hope someone can explain whats going on....although, regardless, I can't imagine this is desired behavior!

    I dont have my car yet but sounds like a dumb behavior. I would first off send a feature request to Tesla telling them you want to be able to have AC stay on.
    I wonder if it has to do with the "overheat protection" mode being turned off in your car? not sure. maybe another owner has some ideas for you.

    It has something to do with not detecting someone in the driver's seat. Definitely an annoying occurrence especially when the driver is not in the car while passengers are staying behind.

    Yes, I noticed that the precondition period ends once any door or the trunk is opened.

    If you pre-cool the car, it turns off as soon as you open a door or trunk.

    that is the same behavior i experience. like someone else mentioned, probably because driver left the car so it thinks no one is in the car and will probably get ready to lock when you walk away type of deal.

    I guess the car wants the driver to be in the car first. There is a lot of annoying things about this car when there is no one sitting in the driver's seat.

    Model S works the same way, as far as I can tell. I've never really understood why and never liked it, but it seems to be "normal."

    I use precondition daily and on my car if I open the driver's seat the AC will continue to run. If I use the other doors or the trunk that's a different story.

    My car does exactly the same, so I don't think is a sensor problem. Could this be so people don't plan on leaving someone unattended in the car? like say a child or a pet?

    My guess is simply poor algorithm/ logic. Getting Tesla's attention and certainly developer time to review (and improve) seems like your typical long shot.

    Still better than 90% of the other cars you can buy. The driver has to get in and start the vehicle to get the AC running in everything else I’ve ever owned. Of course I’ve owned other cars where you can pre cool via app or pressing buttons on the fob. But it is almost the same as using the phone app to me.

    Let’s say you have a backpack in your front passenger seat and leave the car. You want your car to run with the A/C on all the time?
    I get what you are saying and it’s simple in other cars as you just leave the car running. But there is no on/off in a Tesla, so this is the way it works. It’s a feature and probably nothing that will change soon. But I suppose you could press a button on the screen that says leave on for x minutes. That would work. And there is something coming soon about party/camping mode that may assist here

    If I'm pre-cooling (I've used the app to turn on A/C at a desired temperature), and I walk to the car and open the door to put my kid in, I expect the A/C will continue to run after I shut the door. Because I have 2 kids. And that means I have to get the second kid in and strapped in too. I also have to load the groceries. I will get my kids in and buckled before I put the groceries in, and as long as my phone is within range of the car, that A/C should continue to run!
