Got update 2020.28.5 yesterday. Now the battery will not charge. It sits at 120V and 0 maybe up to 2 amps occasionally but sits at 0 most of the time. Then, after a bit it stops charging and says to reset.
Anyone else?
I usually wait until it’s down below 40 before charging it back to 85-90%! I don’t charge every night.What are you charging practices?
Every week I’m losing 1-2miles on my SR+ With 24kmi. Estimated range of 210 when slider set to 100. Was told the initial degradation would ease off, but it’s been on a constant pace since I got the car. It’s turning into a game for me at the moment and I’m looking forward to 199miles at full charge.
Pretty ridiculous seeing a LR model 3 with 100,000+ miles that lives only off super chargers have less degradation than mine. Obviously a contributing a factor is the LR battery.

That simply doesn’t work if the capacity isn’t there!You haven't lost that range. Your battery needs recalibration and you'll gain back all the range that you have lost.
Charge it up to 90% each day and let it be. Most days, I use 5% of the range and I still charge it to 90% each night. My car is also always plugged in whenever possible.

I feel you. It’s really sad and unfortunately everyone first assumes it is just you, can’t be true.I don’t believe this to be correct. I have done numerous “recommended procedures”, however none had worked. Especially the 10/20% to 90%.
Sorry, I'm new to Tesla. where did you get this report from?Went to 524 once after the update and now hovering around 500km estimated at 100%. Just under 5% degradation after one year if we go with the latest charge estimate of 501.06

i’ve been told that and tried every recalibration things possible, it’s simply missing capacity since we got it and BMS estimates don’t drift alot.
I have same issue, car is 9months old and I’ve been following and trying all recalibration/charge habits and options for 8 months now. Car still has only 208 of the /240-250miles (rated range). There is no software fix for the few people that got shafted without a solution.
*edit*
If you still have doubt, read my other posts. We only have 39.x kWh useable on a 90% charge, scandalous for a new car
Sure.That really sucks and I'm sorry to hear this.
Are you able to describe your charging habits? I'm trying to figure out what may have caused this severe degradation other than just being unlucky with a borderline bad battery.

I'd keep escalating your issue. If you get no satisfaction with Tesla, take your issue to the local consumer protection agency. Obviously, I don't know who that is in Eindhoven, all I know about Eindhoven is the football club is PSV!Sure.
I have my own Tesla wall charger (11kW max) and charge to 80/90% and rarely supercharged. Normally it stays between 40-90% but we also tried numerous calibration methods for 8 of the 9 months we own it, nothing helped.
In first month of owning the car I already planned a SeC visit about the capacity, it had -10% already first charge.
everything “works” but the worst is immediate value loss on my dreamcar and the charge limit between Superchargers has to be set higher then needed: i.e. 95% instead of 80
Try this and report your result....
Look at any of the consumption graphs. Take the Wh/ml and range.
Note battery % (as a fraction).
kWh = (Wh/ml x remaining range) / (battery % x 1000).
Ex. (240 x 110) / (0.5 x 1000) = 52.8kWh
I always get 52.5kWh as the answer. But not tried since V10.0, will report back.
I feel you. It’s really sad and unfortunately everyone first assumes it is just you, can’t be true.
It’s probably also a “factory” fault like I concluded my SR+ battery is. Some of the bricks are probably defect but not enough to trigger errors and warnings so you aren’t covered under warranty.
It’s capacity dropped so fast most likely because the full capacity was never there, the BMS only had to learn it’s not there from the start. (Through charge cycles)
My current example from SR+ 9months old:
Lowest brick cell (Resting) voltage: 3.098V
Higest brick cell (resting) voltage: 3.178V
Even peaks at 106mV imbalance (which is huge!) when slowly driving. The above however is while staying parked with HVAC on to drain to 2% with 0.9 kWh remaining. (Again, trying to ReCaLiBrate the battery)
The battery is only “as good” as it’s weakest brick. Once the worst brick reaches minimum voltage, it’s done for the other bricks also
Tesla probably scraps fully produced battery packs under 46 kWh but not above.
What does it mean (simplified)? You can get a brand new Model 3 SR+ with either 46 kWh up to 54.45kWh (the second is where the EPA and WLTP rating is based on). This is at least advertising very much in favor of advertised range.
Not all batteries are created equally, I have yet to find someone with a worse pack then us. (We got it this low!)
Well today I went in SeC for a huge dashboard rattle (second time!) this time they fixed it. At the take in, the Tesla mechanic asked me if I liked the car, I said yes except for the capacity loss and that Tesla couldn’t say anything about that last SeC visits, because it’s company secret the State of Health of the battery..I'd keep escalating your issue. If you get no satisfaction with Tesla, take your issue to the local consumer protection agency.

I guess this is the degradation thread eh?
37,000km and I'm going decidedly good, but I think my numbers might hold some meaning anyways. Early 2019 LR AWD Model 3, originally rated for 499km (website now lists at 518). If you go by the old range calculation I'm only down 2.4%, but going by actual kWh capacity it's probably closer to 5%. If you go by the new range calculation, it's about 6% degraded.
I'm down to 487km displayed at 25C battery temp after sitting. It was as low as 485km. The additional "2km" happened after something similar to "calibration" (charged as high as it let me, 98%, discharged to... 9%?, and charged back up). It's absolutely insignificant and I still think the calibration stuff is just confirmation bias. I also lost displayed range doing something like this once.
I absolutely think this is down to battery lottery. We do drive gently and follow fairly good charging practices, but about 31% of our charging (by kWh) has ended up being DC Fast Charging due to trips (mostly Supercharging probably, but a good amount of CHAdeMO). Keeping it in the garage (which fluctuates between about 10C-25C depending on season) probably also helps.
Almost all the range drop occurred in the last 12,000km (which was where we did a decent chunk of our Supercharging as well). SMT reported somewhere around 76.8kWh 6000km ago. It's now around 73.6kWh. This period also had the car being soaked in the cold outside more. It was interesting to correlate cold and increased DC Fast Charger usage with sudden drops in capacity for an otherwise very well performing battery. Note that at 76.8kWh, the car still reported 499km due to reasons I'm sure have been discussed in this thread.
I honestly think there's something uncharacteristically good about our battery. Achieving rated efficiency has been a breeze for us, and we often get 130Wh/km at highway speeds (either with windows down or the AC going). There's also very little imbalance under heavy load, even at low SoC.
No humblebrag intended, I just think it's good to have perspective on what's maybe "normal" or "good" to compare to. Sorry if it makes anyone feel bad though!
Bittersweet, but I'm glad you realize you don't really have anything to "gain" or "calibrate" at this point. Every post I've seen from you has made me feel so sorry for your experience. I don't hold Tesla, as a corporation, in a very positive view to begin with. Not helping out someone who clearly has a bad batch of a product is just shitty operation, period.
According to what I've been told there is no "recalibrate" despite what people write on the net. I following the owners manual and only charge to 100% for long trips. I don't let battery woes keep me up at night.Glad I don’t get the “JuST rECaLiBraTe” replies and such and people actually listen here..! Very much appreciated.
