Thanks for that reply, @manttium. Yes, it is definitely apples-to-apples -- at least in the first 2/3 of the chart. At least until 50,000 miles, the fleet benchmark is 13 other vehicles; by 70,000 miles there were just 3 other vehicles, and the flat line after 80,000 miles suggests that I'm...

I've been tracking battery range degradation religiouslyon my two Teslas -- a four-year-old Model X and a two-year-old Model 3, and differences in battery performance versus the fleet average are truly remarkable. My Model X 90D, delivered in June, 2016, started at 264 miles of range, but is...

No, unfortunately it was in warranty when I first saw the light intermittently, but it wasn't clear it was a real problem (lots of people on the forum were reporting these warnings as a software bug) until the light became continuous and the ride got sloppy. By that time, I was over 50,000 miles.

Yes, that was my plan too...but the warranty mileage crept up on me, since 50,000 miles came a lot faster than 4 years did (2.5 years to be exact). Given their connected-car telemetry, I was surprised not to have gotten a notification and offer from Tesla shortly before I hit the warranty wall...

When I left a Tesla Service center a couple of months ago after a complete tire swap-out for my MX 90D, I noticed an "Air Suspension Needs Service" warning. But after I made a stop on the way home, the warning disappeared. Then I saw it again several times, and it rarely stayed on for more...

I have experienced this, too, on 2018.42.3. Last several charges:

In the Rte 2/128 area northwest of Boston, I often see 4 or 5 a day, not counting my two!

The Woburn Supercharger location appears to have totally dropped off the newly-revised Supercharger map from Tesla. There is now one planned in 2018 for Burlington — the only Find Us | Tesla Does anyone know the backstory around dropping Woburn?

Actually I just got it OTA on my Model X because a mobile service tech worked on my car this morning. Here are the release notes -- tire pressure units and automatic heated steering wheel.

A group of graduate students I know from Harvard and MIT are looking for volunteers to participate in a machine learning / data-mining project designed to give new insights about driving, performance, routing, etc. to drivers of Tesla automobiles. They're seeking Tesla drivers who are willing...

All -- I know the leader of the team who's conducting this study. They're solid, reliable graduate students at Harvard and MIT who are committed to really using machine learning to help give insights to us Tesla drivers. I'm participating, and I recommend this to my fellow Tesla drivers. Michael

I hadn't noticed it, but during some minor maintenance on another matter, Tesla Service swapped compressor lines on my car. I have no idea the impact, since that work was done in January and we don't use a whole lot of A/C around here (New England) this time of year!

I agree, and TeslaFi (the source of this logging data for my car) doesn't chart data for the intervals (I.e. Instead of "1-5 miles" one can only get "over 1 mile", so the long drives get averaged into the "over 1 mile" trips). I've put interval plotting in as a feature request.

Temperature and trip distance have a dramatic effect on efficiency in Model X. Here is my current chart of energy consumption vs. temperature on my X 90D for different drive distances over 18,000 miles in New England (hilly, but not mountainous) -- 339 Wh/mile lifetime. Note that rated...

One critical detail is missing from your report, and that is what your strategy is for charging -- that is, what is the average state of charge (%) when you decide to charge, and what is the average SOC when you finish with the Supercharger? My understanding of the supercharger performance...
