    I know this thread has been done before, but I am looking for some fresh data. For the S85 folks out there, whats your milage, and whats your 90% rated miles. I am at 101,000 miles and my 90% is 203 rated miles... That seems too low, but I want some more data points. I still love the car!! Appreciate the help! Cheers!!

    That is very low. Was there a sudden drop that you can remember?

    I don't generally use 90%; I always use 80%, but I can extrapolate a little bit.
    Mine is a March 2014 S85. It has 54,700 miles on it. At 80%, it's about 205-206 miles most days. So that would be about 230 for 90% if I calculate the ratio.

    Yes, I lost 20 rated miles about a year ago, and the service center chalked it up to new software, but don't buy it. Im going to have my car serviced soon, so I want to be armed with as much information as possible before I bring it up again to service. That is my thoughts behind this thread.

    2012 Model S 85, 80k miles, ~222 miles rated @ 90% state of charge.

    I am not sure if this is a coincidence: I noticed more reported miles at 90% SOC during the times I happened to charge my car when the HVAC was in range mode.

    2012 original A battery - S85 - 183k miles - 90% 211 to 213,, 100% 235-238.

    OP, I would charge to 100 percent three days in a row, and ideally drain to less than 20 percent before or in between to get proper battery balancing. Try it out.

    I get 228 @ 90% on my mid 2013 S85--FWIW I do very little supercharging, almost never charge above 90%, and almost never go below 20%. I have a B pack. Never replaced. About 53k miles.

    From the collective data so far, it seems like your car is about 25-30 miles low, which is about 8-10kWhs that is missing. I would not think that's OK.

    Document everything, just in case you decide to take action(s).

    I am in that process right now with my S60.

    Good luck.

    So, I brought it up to the service center again, and was immediately dismissed and told "well, degradation is normal in electric cars" Like I'm a total moron. Without even knowing who I was, or looking up my VIN, they just said, "Ya, thats normal"...... Which I am convinced it is not. How do I push the issue? Is there a question I need to ask, or some data I need them to pull to verify it? I feel a little in the dark on this, where I know something is wrong, but I have no idea how to prove it. Thoughts appreciated!

    Two words, executive escalation.

    submit it from your my tesla account, may take a week but it will go to the top and then come down to get looked at and fixed if needed.
