My 60 has consistently charged to 90% daily, sometimes multiple times a day and this has been ranging in the 175-177 mi range @ 90%. I had my speedo display replaced on Friday and updates software to the latest 6.2. On my first nightly 90% charge, I hit 176 mi and all was good. Last night I charged to 90% (from 48 mi) and it topped off at 171. That seems a pretty extreme drop in 1 day. Any ideas? It has been extremely hot for the area (90's).

Or the replacement of the unit also lost all previous calibration data and the car has to build it up again over time.
I have started to gain some of that mileage back. Very much like Kabirakhtar, I have been getting 177-178 and then it has stepped down over the past few months to 175-176 and recently down to 170/171. The latest charges have been up to 173, so I am hoping it is calibrating. One thing I have noticed, after periods of sitting where there is a large vampire drain (long time in the heat or leaving for days at an airport), that seems to cause this lowering in the final charge. I almost wonder if there are losses that the calibration mechanism isn't accounting for which is throwing the calculation off.
Learn your car.... these mileage figures are at best a guess (based on your driving habits, etc). If there is a change in the habits or software update, you will notice a difference in this 'guess' because the algorithm resets. Over time, it migrates to the numbers you are used to as more driving/charging takes place.
My car has been plugged in for the last week and every 3 days it wakes up and charges for an additional 9 miles. Someone suggested that was not true vampire, but needed cooling. Is it possible car charged to same amount and then used some of that charge to cool the car? You mentioned temps in the 90s...
I also have a 40kWh and my loss is now up to around 7 miles after the last update a few weeks ago. My update was from 101.36.2 to 2.4.239 version of 6.2. Service center has ticket open with engineering, but no response so far. The reported range seems to be accurate. I usually use Ideal and drive at 260Wh/mi, and my decrease of estimated ideal range matches the miles driven. Either the previous firmware masked degradation, or the capacity calculation is off in the new firmware.
