latest upgrade effected model 3 parking drainage?

[scomoO]

After last upgrade I have noticed the model 3 is draining faster.. I have no sentry on (as before)
Does it have anything to do with new “passive authentication” toggle being switched on?
Thanks

The only new part is the the toggle allows you to turn off the Bluetooth key.

Have you tried the 2 button reset of your car?

There's another thread that indicates that it may be an issue with the release.

Here's one:

Anyone seeing significant battery drain after updating to 2023.12.5? Since I updated, I am losing around 1% every 12 hours, without Sentry Mode activated. With Sentry Mode activated I am seeing almost 1% per hour. Did the power off and steering wheel resets but did not improve.

I noticed increased draining BUT at the same time it has been pretty warm here and I accidentally turned on the cabin overheat protection when i was tinkering its off now for sure i lost ~25% in 1.5 days parked. And no i wont turn off sentry mode unless im in a secure garage…i upgraded tues night and had to park it wed at our motorpool to pick up a company car…

I’ve read that if your 12volt lead acid battery starts to degrade, the computer will need to wake up your car far more often to allow your high voltage battery to charge it. That waking and charging process will be seen as more drainage.
So maybe your 12v lead acid battery, (if you have an older model) needs replacement.
Just a thought.

thanks. November 2020 is the age of the model 3. Could the lead acid battery go in just that time?

It can for sure. At least, it’s reaching its end of life. Which means it may need charging more often. Which could keep your car waking up to charge it. Which could increase frequent drainage.
I’ve seen threads were 3-4 years being common enough. Some last longer, but not always.

From experience, the Model 3 warns about the battery well before not sleeping occurs.

From what I’ve read, the warning your battery is about to die, is not early enough.
I think we’re talking about an aging battery at the point before it dies. When it may need more frequent charging.

It seems like Tesla has found out what it is via mobile diagnostics-

Power Conversion System (PCS) failure​

Thank goodness it is still under the initial warranty! Because I have seen elsewhere that sometimes it’s not covered

The regular 4 year warranty covers everything, so it includes that. The extended 8 year warranty is on the battery, and the PCS is not considered part of the battery, so it's not covered under that extended time period.

What is the fix for that failure, and the cost of it was not under warranty. ?
