I have a 2021 MY delivered Dec 2020 with about 23K miles on it. I would note that because I live in a city, the car has been charged almost exclusively at Tesla Superchargers.
I know there are many threads on "expected" and "normal" capacity loss (even though Tesla does not mention this unless you are talking to their service department AFTER you have purchased a car). The typical loss mentioned seems to be 3-5% in the first year, and then maybe 1-2% in subsequent years.
I first became interested in this as I noticed at 100% charge my car recently shows a range of under 300mi (assumes 250wh/mi) whereas last year I recall this being in the 315-320mi range when I charged. (I typically look at battery percentage and not estimated range, so I have no idea when this number actually started to decrease).
At 16 months of age and 23k mi, TeslaFi and Recurrent are telling me my battery has lost about 9% of its rated capacity, which is even outside the "expected" range. This lines up with what the car is telling me in the UI.
I have taken this up with Tesla support, who have run diagnostics on my battery. They will only tell me I have "some capacity loss, but within the normal range". They will not provide me any detailed data from what they are seeing on their end.
I have a few questions for others on this board:
1. It is normal for Tesla to not share their diagnostic results? I am concerned because third party apps like Recurrent are definitely telling my the capacity has decreased well beyond what is normal in the first 1-2 years.
2. Has anybody else experienced capacity loss at this scale under these conditions? How did you deal with it? Was a battery replacement or other remedy possible even though this hasn't triggered the 70% level in the warranty?
3. I have seen many threads parroting the comment from Tesla support that 3-5% range loss in year one of ownership is "normal". However, I cannot find any marketing material, disclaimers, whitepapers, etc. from Tesla supporting this assertion. I am trying to determine where I could have gotten this info from Tesla (not from a message board) before purchase. In fact, the only official statement on battery capacity I have been able to find from Tesla is that the battery should retain 90% of capacity by 200k miles (Tesla: Battery Capacity Retention Averages 90% After 200,000 Miles). This is obviously very different than what I have been told by Tesla support and the common knowledge on this board.
