Yes, now showing ~477 km at 100%. Our high back last year was 495Km. Our Teslafi shows a ~4.2% degradation which seems common.

I'm curious - how often do you guys do a road trip and super charge back to back?
After a summer of road trips to Ottawa and Montreal, my battery is reporting 505 (20km loss from the top 525 =~ 4% degradation as expected).
Still puts a smile on my face when the pedal hits the metal. A week ago, an Land Rover tried to beat me off the line and I came back and pulled past even though he had a good head start guzzling gas

I am driving Toronto to Montreal (and sometimes Ottawa) about once a month since I got my car in October 2018. But again I didn't have any loss in reported range until June 2019.
Another thing that points to a software change is that my estimated range is now often higher than my rated range even though I'm only getting 90-something percent efficiency. (You can see estimated range through TeslaFi, the Tesla rest api or through the energy app and choosing the 50km distance setting).
My car is at 90% SOC with:
rated range = 419.6 Kilometers
estimated range = 430.68 Kilometers
And my previous 50km has been two drive of about 25 km each one with 91.8% efficiency and the other with 93.4%.

Mine is right there as well, 1 year old AWD with 33K KM. From TeslaFi it started going down noticeably in July of this year. Have only charged to 100% twice in the year I have owned it.

I got my SR+ on May 31, 2019, have driven just over 10,000 kilometers and the average during this time has been 134 wh/km. I typically charge to 80% and when i first got the car i was getting 324km starting range and now I am down to 286 km as of a couple of days ago. I have only charged to 100% a couple of times but noticed this weekend that when i did that i got 357km range. Not sure what to make of this and if i should be concerned? thanks

You must have been charging to 90% when seeing 324km because 324/.9=360km. And 286/.8=358km. So those numbers are both consistent. Though they should calculate out to 386-ish km. But all indications are that there is some software thing going on (no one can really tell you better), but it seems to me there is a consistent 5-ish % of 'missing' range on many cars.
it still seems odd because at 80% of 386km, i should be getting 308 but am at 286km, can't have that kind of swing in 3 months of owning the car.

That's interesting. Every other AWD in this thread from Sept 2018 seems to be down around 480km at 100%. How many km are on your car?

Agreed, that's why to me this points more to a software thing rather than battery degradation. But it's near impossible to tell.
One consolation is I'd you are averaging 135wh/km you are getting better than rates range by 10% or so. So if you actually drove to empty from 100% you would get better than 386km anyway. Not really apples to apples, but it's something.
I am in the exact same situation. 287km for 80% and car is 6 weeks old. I charged to 100% today just to see what it would show as the upper limit and it didn't exceed 359. I hope it's the software because losing almost 30km of range already would be quite disappointing

That's an interesting point to think about..... Casmium says he has only supercharged once and still has 499 and is a Sept 18 build like mine with 30K KM as well. I was at 499ish until Aug of this year when I took a long road trip (7k KM) and almost exclusively supercharged. Thats when I started seeing it drop. Now that I am back and am not using super charging any more, I am seeing a slight uptick in range from my lowest point of 474. I am at 482 now. I have tried the "calibrate" various methods and did not have much of an impact. Seems slow and steady climb in range with my HPWC charging at home.
edit: Went back and looked at TeslaFI and can pinpoint the exact start of range drop quite easily, it was July 15 on FW 20.4.4 at 21K KM.

Forgot to change TeslaFi's schedule and ended up with 508 at 100% this morning - same as Friday when I left for a trip up to North Bay over the weekend. Supercharged twice for the round trip. 110V/12A charged maybe 150kms while at destination.
It is weird some cars are showing 20-30km loss over a short period and others are fine.
VIN range?

Just another observation, I usually leave my car in the % rather then km. Sometimes when I park it in the driveway rather then the garage if I leave home with 71% battery and drive to work 4km and arrive with 68%-70%, at lunch it will show back to 71%, my guess this is something to do with temperature outside in the morning or overnight, and then warming up in the day. This does not happen when I leave the car in the garage. I do remember last winter when it was really cold the Percentage counting up as I drove on a couple of occasions as the battery warmed up, and getting a big when it had the snowflake and finally warmed up. I'm just wondering if it would also make the range loss seem greater on a cool morning. Maybe compare after charging during the day vs night

Picked up my car in October of last year. 20,393 km. My 100% has been consistently 482 - 483 km the past several months.
I haven't gone back and reviewed the data, but it seems that for those who are reporting no loss of range, they have a fairly high daily usage - 80 km. or more. Perhaps the usage is as important as the charging? My 6 week old SR+ has an estimated range of 347 km. My daily commute is between 16 and 35 km.
