Help: Horrific battery draining while parked in long term parking structure - I've got 12 days to go

[mephiska]

Hello,

I am out of the country right now, over 6,000 miles away. I left my car parked in a 3rd floor of a long term airport parking structure. I charged it to 90% before I left my house, arrived and parked at 79% on the late night of 11/10. I made sure to turn off sentry mode, turned off preconditioning, turned off cabin overheat protection, disabled any tessie routines I had and left the car to head out of the country. I've been checking it because I noticed significant phantom drain even though it shouldn't be running anything. It's losing 4-5% per day so far.

It's now just a couple hours past 3 days and my car is now at 63% battery. I've lost 16% in about 80 hours parked in a parking structure!!! What the hell is wrong? The car should be going to sleep, right?

If all you need is 11% to get home, you should be fine, no?

What software are you on?

Whatever the latest version is for my car.

But still the phantom drain is absurd. I've seen people say to expect around 1% per day of drain when car is left to sleep. This is unacceptable.

disabled any tessie routines

What do you mean by tessie routines?

It sounds like you have something, probably on your phone, keeping the car awake. Disable any apps except the tesla one, and change your tesla password.

By checking your app frequently, you are taking your car out of deep sleep and thus are not conserving the battery while parked.

Also let's math that out. I've got 12 days to go. If I am currently at 63% battery and am losing 5% per day, that's 60% battery drain and will leave me with 3%. So no I'm not fine.

You should be able to leave a tesla in long term parking for 2 weeks and not return to a dead car. At the current rate of drain I will be doing just that. Something's wrong here.

I signed out of my Tessie app completely, even though tessie says it won't take the car out of sleep.

Don't trust it at all. Change the password.

Additionally, Summon on Standby will apparently keep the car awake.

define frequently. I have left it 8-12 hours between my checks, and come back to find it's lost 3-4%. How long before the car goes to sleep? I've seen it go to sleep while at work in much less time.

I don't have summon, but I'll try changing the password to see if that works. I opened a service ticket as a backup.

Teslas sleep after 30 minutes of activity. I'm definitely not checking it that frequently, not checking by multiple hours. Something else is keeping it awake.

Changed my password. I'll wait a full 48 hours before I log back in and check on the car and see how the battery drain is. It was 63% when I last checked. Phone app is logged out, tessie app is logged out with password changed so authorization should be cut off.

Are you 100% sure Sentry mode is off?

Are you 100% sure Sentry mode is off?

Sentry mode and Summon Standby are the two main battery killers.

Make absolutely sure that neither are functional.

Note: Summon Standby is on by default if you have EAP or FSD license.

 

[mephiska]

Are you 100% sure Sentry mode is off?

Yes, I've checked multiple times that it is off. I actually turned it off several days before I planned to leave because I know how much of a battery drain it is.

Thanks, yeah I don't have EAP or FSD, so no summon should be at fault here.

Maybe try turning it on through the app for a couple hours, see if the consumption goes up. Then turn it back off.

Maybe it says it is off but it actually is not. I have had this happen a couple times, where the app shows no sentry mode is active but I get to the car and there are sentry events. Just an idea worth trying

I opened a service ticket with tesla and hope since this is such a software car they can look at the logs and say "yeah this 3rd party app is keeping your car awake" and can point the finger at something. Or there is something else wrong with my car, maybe Sentry is still on even though everything I've checked says it's off.

And if the battery gets down to below 20% or so, maybe you can have a friend or family member go drive the car and charge it up a little. Do you know how to remote start to allow someone to drive it without a key?
