Sorry but in my opinion this is only evident if you have done several charging sessions with a warm battery. If I am charging slow (11kW) with a cold battery I also have a lower nominal full pack compared with charging a warm battery or with 22kW (which is also warming the battery). Please see the Teslafi curve with it's bottoms and hills to prove this statement.

Interesting, Thanks! So you have a decreased range from 373 to 368km over 15000km. That's not nice, but 2...3km each 10000km seems to be not abnormal. To make sure it is really only degradation we need your final voltage. To look to the exact typical range makes me also sometimes nervous, but with the next charging session it is typically back on the old value, so who cares ?
The reduced charging speed is for me the bigger issue !
I went from 373km to 365km (not 368km) on that graphic.
Only 15.000 km and about 6 months have passed.
Do you think that's ok? This was no happening before July 2019.
If it stopped i would be "ok", but if i keep losing range at this rate i will soon have a worthless car for long drives.
And this is obviously not degradation, because it didn't happened before at this rate.
Tesla clearly just want us to dump our "old" Teslas and buy new ones.
I hope the class action suit kicks Tesla's ass big time.
Yes, I cannot wait to buy another Tesla after this..
I hear you.
But the problem is that, currently, there are really not many alternatives....
Unless you go ICE, which i won't.
Looks like it was a faulty drive unit, which was replaced under warranty. Battery/DU warranty expire in August of 2021, I'm seriously considering selling before then. I can't afford a $20,000+ battery replacement out of warranty. At that point, I might as well dump my Tesla at a junk yard and get a Prius. If I do sell, I would have to consider a non-Tesla EV. I have very little trust in Tesla's battery tech at this point, and even less in Tesla's desire to "do the right thing" in any situation.
I will wait for Toyota or something like that. Will keep this lemon until I am a completely fed up with it and then never again
Sorry but the last drop to 365 is not relevant. As you can see on my Teslafi chart it differs by 10km. You first have to do at minimum 2 or 3 more charging sessions before you should believe the 365km. Only my 2 cent.
quick update from me. I have driven quite a bit since they got me. Aprox 43,000 miles. Range has been dropping rapidly since then. Much faster than it every did in the previous 6 years. My cell balance is also getting worse fast. I have been monitoring it for many years and it was always around 3-5 mV when charge to around 90%. It has been pretty consistent. Now it's about 22 mV at 90%. I also feel like power is lower than it used to be. The car still refuses to charge to 100% most of the time. On a supercharger it usually goes to 99% but on AC anywhere between 95 and 99. Charge rate at the supercharger is a mixed bag but the trend is also down on average.
Keep in mind this graph is almost 200k miles and 4 years of data.

For those who use technical analysis (charts) for investing I'm sure the projected average of your "battery level" from 84K -230K miles (pre-software restriction) is pretty obvious, but it might be helpful to show that projected line with the actual average to clearly demonstrate the disparity.
The only thing I have seen is that they have filed a motion to protect discovery from public disclosure. So I would say that doesn't bode well for mediation coming to a successful resolution. (But hey there is still a few more days to come to an agreement or extend it further.)
I got the answer from Tesla:
"after performing an online diagnose please be informed that there is no issue with your HV Battery.
When we replace battery packs under warranty, we guarantee to install a pack with the same characteristics as the one that was removed. (not as it was when new)
We have complied to this procedure.
It is expected that the HV battery in your vehicle is not performing as it was when the vehicle was new.
Please also advised that the capacity and other characteristics like accumulated wear etc. are all equal or better to the pack they had installed before.
If you perceive the range to be lower than expected please perform a test drive and test vehicle range. Attached you can find the data that we need for further diagnostics. The same data is needed for charging issues.
If you believe that heating performance is inadequate, please perform a test. Set the heating to maximum and not AUTO on the MCU. Please test heating on this setting and if you still perceive it to be too cold, please provide a timestamp of this test. Please also give us the information where the heating performance is perceived to be inadequate. (footwell/dash front/rear etc...) This issue can then be investigated online.
As soon you have the data please schedule an appointment and sent this data with your VIN number included.
Please be informed that if the diagnose is not covered by warranty cost of diagnose will be charged."
Also attached was an excel file with columns to be filled: date, time, range, range remaining, etc
Even if my range is 4-5 km lower that my last test 1 week before it died, I am OK with the car and Tesla, considering the KM.
It appears to me the battery with 100% at 394V instead of 404V, is limited to 80-85% and it has minimum degradation, making me confident it will last a long time.
Hope it helps.
Unless mediation results in new replacement batteries like the 14 module 350V pack for all capped owners, I would like this to go to court with full public disclosure for two reasons:
1) to get a successful resolution even if it takes longer than resolutions
2) to get the full facts about the issue and the internal comms within Tesla to understand what they knew and what decisions they made and why they made them
When I buy my next EV I want to purchase from a manufacturer that treats its customers fairly and honours its commitments even if financially painful.
