Issue with climate turning itself on during night

[michelerusso88]

As the title says. The car is only just over two weeks old and recently in the last couple of days the climate has come on somehow (car isn’t being driven). By itself. It must have been running for ages as the app sent me a notification saying the climate has been running for an extended period of time.

has anyone else had this issue. Car was plugged in so it must have been using the electric from the wall charger ?

 

[ACarneiro]

No, it’s never happened to me and I’ve never hears of this happening.
Is the car remaining locked?

 

[Glan gluaisne]

Is the car set to stay warm, by any chance?

There's a setting to "keep climate on" which will maintain the interior at a set temperature, even when not being driven.

Just checked. None of the doors are open or left partially closed. Climate inside the car is set to off and schedule is turned off. This has happened for the last three days. Never happened initially. I think it’s been funny since the software update.

I’ll try a factory reset

Before you do a factory reset try just doing a reboot. Hold the 2 steering wheel buttons down until the screen reboots. Another option is a "hard reboot" which requires to first disconnect the 12v and then disconnect the HV under the rear passenger seat. Then after 5 minutes reverse the process and connect the HV and then the 12v. Both of those options will preserve any custom settings, etc, you have compared to doing a factory reset.

Others have had had similar to this issue - I believe it was potentially something to do with accidental triggering of features when using an Apple watch.

[edit] Give this thread a look Climate has been on a long while!

If you're doing a 'hard reboot' then you don't disconnect the 12v first as you need to power the car down on the screen and then disconnect the HV battery at the penthouse connector 'after' the contactors have opened. The 12v is disconnected last and reconnected last. You always isolate the car from the HV battery before doing anything else.

If you mean Cabin Overheat Protection, that’ll keep the interior below 40C. It won’t heat it up at all.

I had this problem of the climate turning on after I had parked the car in the garage and indeed, I think it was potentially related to the Apple Watch App I had started using. Both the Watch App and Tesla have had multiple updates since I last had the problem some months ago, but maybe I am just a bit more careful when using the App these days. Not really sure what the cause was but it has not been a recurrent problem and hasn't happened for a long time now.

Thanks for all the replies. Haven’t used my Apple Watch since lockdown started but I have done the two button reset. Car is due in at the service centre anyway next week to fix the pickup issues so I may just mention it to them

Let us know if the SC provide an explanation. I was never sure whether the Apple Watch App was the real culprit for this or not.

Another valid idea is to change your Tesla account password. If any apps are logging in to your account then they will all sign out.

RIGHT - I believe the info i received from a Tesla Tech not some third party on the internet

I’ve had this too. Check your scheduled charging/scheduled departure settings. The settings are not at all intuitive. You can easily end up with scheduled departure set without knowing it. Mine was preconditioning in the early hours. Make sure scheduled departure is definitely toggled off.

LOL, ok. To each his own, but @MountainPass is a very trusted name in the Tesla world and definitely know what they are talking about. Many of the Tesla SC techs are just out of high school and I find I often know more than them when I dive deep into technical discussions with them having owned Tesla's since 2012. Looks like you joined in 2020 so you are new to the Tesla world.

Ouch ... whatever the outcome of this dispute you'll find that Mr H is not your average "opinion without foundation" guy! He works with Tesla's in a professional capacity and is a trusted trader on this forum ... as I'm sure he'll let you know!

The validity of Tesla techs' advice has certainly been found to be questionable in the past, as you say. It will be interesting if a definitive answer can be obtained on this one.

I own a Tesla model 3 and I have the same problem. The car turns on the climate system without receiving a command. Often control is on for four hours before it shuts off. I received the information on my iPhone. I need an answer how to keep the car asleep. Thanks

have you followed the advice on this thread?
1) double button reboot
2) if you have the watch app get rid of it ( for now)
3) change your password to rule out any third party apps or others in your family who might have access

If you do all of that and you are still having a problem I suggest you raise a service request but note the exact ( as possible) times that it happens since Tesla will want to check your cars logs probably.

edit
also I assume you do not have the car set on scheduled departure by mistake because that would also do it?

I once "pocket dialed" the HVAC to come on when I left the Tesla app running. This was in winter and it used up 30% of my charge! Now I always close the Tesla app down after using it, just to be on the safe side...
