Actually took delivery Nov 2018 right after the car was built, I live fairly close to Fremont factory in Bay Area. My commute is couple miles per day and we have another leased car to add miles. Car is always kept at ~80% SOC. Saw some members here are getting ~280 when fully charged at 100% on their AWD as well, so hoping anyone can shed some light. I feel that 27x miles at 100% for a lightly used battery is not normal, maybe I should try to calibrate and see.
You don't drive much, could be totally BMS drift. If the SC appt doesn't give you any answers, you can try recalibrating, but that seems more miss than hit. I would also consider changing your charging strategy. There's no pattern that I can see in why one car does better than another. Some people charge to 90% all the time, and some charge to 60% all the time. Works for some, doesn't work for others. You can only try. If you charge to 80%, sounds good to me, but it's more prone to BMS drift. I'd try keeping it at 90% SOC for a couple weeks, and if that doesn't help, change to something like 60% or 70%.
I own a LR-AWD, 10/2018, 10k+ miles. I started charging to 90%, since I got it in Winter; then changed to 80% in late Winter, when I realized I didn't drive that much; then changed to 60% in Summer, after reading the battery deg, scientifically explained, thread.
Battery Degradation Scientifically Explained I charge to 80 or 90 if I need to make a trip. I don't baby it, I've taken it under 10%, and I got it when it was zero SOC. So, if I've been more careful, it's only because I thought I should take better care of it.
I didn't have deg when I started, and I haven't had any still. Anywhere from 308 to 312 miles. Can't say why, just luck, probably.
Not sure what to belive at this point.
