    I had my M3 at my local service center last week for several items including the car was dead when you entered and could take several seconds to a min to wake up. They updated the software to 2018.24.1 and that seems to have fixed the issue. Now it's sitting in my garage and there's a fan running. Since last week I've had the car not turn off and had to lock/unlock several times to get it to turn off. Now a faint fan is running and I've seen this a couple of times over the past four days. Anyone else having these issues? It's warm out but the car has been sitting inside my garage for almost two hours since it was parked. Also it's not plugged into the wall charger.

    If I knew I wouldn't be asking...

    Anyone else having this issue with the latest software update?

    I was referring to your last sentence. Why isn’t it plugged in?

    Doesn't need to be charged. I'm not asking to review charging procedures.

    Just got off the phone with Tesla Service and they say that's normal and it's the battery cooling fan. While I'm sure that's it in the month I've owned the car it has not stayed on for two hours straight after parking the car. Since the software update we've also had the car stay completely on. While the new update seems to have solved the old problem it's still buggy.

    Plugging in allows it to keep your battery temperature conditioned (cooled in this case) without the discharge of the battery.

    Good point and understood. Under the same conditions over the weekend, when it was hotter than today by 10 degrees, the fan was not running for 2.5 hours straight. I'll keep checking it to see when/if it turns off.

    You may not be asking that but you do need to review it. RTFM. Especially the battery section where you will see IN UPPER CASE LIKE THIS the recommendation to plug in when you can, rather than waiting until you think it needs it.

    That will reset the tablet portion. You can do this while driving and you can continue to drive.

    To do a full reset, while parked, hold down the brake pedal AND the two buttons on the steering wheel.

    Good luck,

    Vin

    Thanks for the reset tips. If it doesn't shut off in another hour I'll do that. It's been on for almost three hours now.

    I have read the fine print and discussed it with the service advisor and he told me what I'm doing is perfect. My interpretation of the manual is not to let the car sit uncharged as draining the battery very low is not good. I'm charging the car to 90% as recommended by Tesla. The service rep recommended to charge it to 100% and take it down to 10% approximately once a quarter. So if I drive the car say 15 miles I should charge it? The car is typically driven 50 miles a day and I have a Tesla wall charger on a 60 amp circuit. One big reason for buying this car was the lack or range anxiety. If it's below 150 mile range it gets charged and if it's above it doesn't.

    “There is no advantage to waiting until the battery level is low before charging. In fact, the battery performs best when charged regularly.” How did you interpret that statement to decide “if it’s below 150 miles it gets charged and if it’s above it doesn’t”? You have a Wall Connector, why not just routinely plug it in when you get home and let the battery management system manage the battery?

    So what's low? What's regularly? IMO 150 miles of range is not low. The car is being used and charged regularly just as the manual states. Seriously, I'm not asking for your opinion on this nor am I recommending anyone follow what I'm doing.

    This is certainly not the way the Model S operates. Did Tesla change this in the Model 3?

    In the Model S the only time it will use shore power outside of normal charging is if a precondition request is sent to the vehicle.

    Are you sure it's not the cabin overheat protection that was just introduced in the 2018.24 update? Even if it's not hot, try turning it off and see if it's erroneously calculating the temperature or something.

    Higher average state of charge has a bigger impact on battery lifespan than does the depth of discharge. IMO, there is nothing wrong with your charging routine. Only thing is, I would recommend charging ASAP if below 20%.

    Not sure about the cabin overheat protection. The fan I hear is coming from the frunk area and closer to the base of the windshield than the bumper. When I got in the car there was no airflow if that's what it's supposed to do.

    After being on for four hours I took the car for about a six mile drive and it's working fine. Whatever it is I can't imagine running non stop for four hours is normal. It's still close to 90 out so it hasn't cooled off much here in the Sacramento area. When I pulled the car into my garage and shut it down the fan is still going. I'll give it an hour to see if it turns off. If not I'll plug it in and charge it and hope it's still not running tomorrow morning.

    Thanks for everyone's input.

    Fully reboot the vehicle. If the problem persists, I would take it in for a checkup.

    I just rebooted it and the fan is still on.

    Fans running after getting home are normal but not for that long without it being charged. That sounds odd.
