So, I didn’t get to drain it yet. Here are the results.

First number is the battery percentage. The second is the kWh used since fully charged.

50–>33.2
45–>35.9
42–>38

This looks like pretty extreme degradation. This is pretty close to the 66.67 kWh on a full charge theory from earlier.
 
My buy back was triggered by the car no longer meeting the performance specs (in addition to the loss of range). There is no definition of "normal" battery loss with the MS the last time I looked so you will have to continue to push Tesla to get the battery replaced. Good luck and don't give up.
 
100%-6% charge shows 60.2kwh used. I am waiting to hear back from my S.C.. worse case I will requestthek to take it back and pick another car. I would prefer to just get the updated battery in this one.

Mine hasn't failed yet. But there seem to have been software changes. The pack seems to always target 42C, regardless of max battery power or range mode. Of course, this could have already changed since I got the fart update. :rolleyes:
 
My specifications are:
Model S P90DL
Facelift, AP1
40.000 km
Built: June or July 2016
Battery: 1071941-00-C

My typical range (European Version!) fell from about 420 km to now 370 km. The German SeC asks me to wait a few months an do some charges 0 - 100 %, it will geht better. I am very sceptical about it. A first full charge 2 % to 100 % in only 4 km more. Are there any European drivers with the same problem? And did you get a battery replacement? Any suggestions, what to do?
 
Why would Tesla replace the battery for a ~12% capacity loss when any gradual capacity loss is specifically excluded from the warranty coverage? (At least in North America it is.)
I guess somewhere is a limit and they will replace a battery for capacity loss. To be on the safe side: Nobody at Tesla would discuss the replacement if the capacity loss is 50 %. And on the other side: A capacity loss of 5 % will not result in a replacement. Everything in between is not so sure. So maybe some forum members know at which capacity loss Tesla will replace the battery, even without warranty coverage.
 
Seeking some advice from those more qualified - I've owned my 2015 MS P90DL since buying it as an inventory vehicle from Tesla in 2016. I've travelled 87K Klms/ 54K miles.

I've attached a Rated test from:
2016 (502 klms/ 312 miles @ 18C/ 64 F) &,
2018 (479 klms/ 297 miles @ 27 C/ 81 F)

The serial number of the battery is also attached, not sure what version it is?

I understand there is a temperature difference between the rated 2016 & 2018 tests, but should I be alarmed at this loss of range?

I trust Tesla - but I trust my colleagues on this forum more. Would appreciated your feedback

What loss of range? I don't think your car is using the EPA standard. 300 miles displayed would like 100 pack levels here.
