Vampire Drain to 0% SOC

[Xd85]

Is this possible? Parked at airport for 4 days starting with 60% SOC. Went into protect mode at 20% last night, but still draining 16% with another 30 hours to go before i get back.

S75D with 46k miles, suggestions of what to do? (aside from having somebody drive it to SC)

I assume you left on Sentry mode, cabin overheat, etc?

It should slow down now that you're under 20%. Stop obsessively checking it with the app, which keeps the car awake. You should have some juice left 30 hours from now.

Though I suppose the question becomes how much do you need to get to the supercharger?

As an aside, reported bug to Tesla when sentry kept on coming on even as I shut it off with the App. 20 miles to nearest supercharger but just 0.25 from nearest L2 thankfully

60% down to 20% in 4 days?
That seems crazy high. Is your AC left on?

nope, just sentry mode that refused to be turned off via app

I had the same problem with Sentry mode draining the battery while I was out of town, and the car needed to be rebooted after a few days (I believe Sentry mode caused that). Since the car needed to be rebooted, I couldn’t shut off Sentry mode, or otherwise connect to the car through the app until a friend rebooted the car. Tesla Service couldn’t connect to the car during that period either.

So now, I won’t set Sentry mode to be on for long periods when I’m not around.

I was really worried about the charge dropping to zero. What do you do if that happens? Is it just having the car towed and recharged?

I heard that letting it go to 0% can cause permanent damage to the batteries. And sometimes people can't even start the car again - even after charging.

Stop making it worse checking the app.
If the 12volt dies the car won't wake but this happens well above a point that would permanently damage the main pack.

Above a point...

Do you mean issues occur at the car draining to 5% or 10%?

It should not do long term harm unless it is sitting at 0% for weeks. There is a anti-bricking buffer built in, you cannot use it; but would protect the battery from over discharge if it drains to 0% and the car shuts down.

Once below some point the main pack won't recharge the 12volt, at which point the 12volt will go dead and the high voltage contactors will disengage.

Thank You!
