My P85 2013 was still on 2019.24.4 and received an update over 3G (!) a couple days ago. First I was clicking it away but now I allowed it to install to test a theory.
I've felt a drop in max power (and more frequent dashed lines) while driving at higher SoC, as well as weaker regen, since the summer. I was and still am getting less range (360km vs 375+ in May).
Obviously I've seen my SuC time double when >70% is needed, like everyone else.
But using SMT for weeks (couple months) now, my nominal capacity has been 73.8 kWh and it does charge to 4.19v @ 98%, so I assumed my car hasn't been #batterygate'd YET and I've been wondering what to do about this whole situation. After the summer I did ask Tesla to check the health of the pack which they reported was fine and tried to make me pay 100€ for the "test" while initially they'd said it would be free to look at the logs. I refused to pay, no news since.
The major question on my mind is whether to launch some sort of formal complaint (with Tesla and/or consumer protection bodies) about the issues I experience. Since I cannot PROVE the battery has been capped (it probably hasn't, yet), and I fear arguing #chargegate on its own will be tricky anyway, I've been delaying doing something about it. But it nags at me that this may be a worse tactic than registering my concerns anyway.
So now I just accepted the update in the hope, frankly, that it will demonstrably cap my battery as well. I won't charge it (close to) 100% the coming weeks, but I assume that a cap should be immediately visible as a lower nominal capacity, and higher SoC for the same actual energy in the pack. Is this assumption correct?
More generally, the "better monitoring of HV battery degradation" on the release notes - which I may see later or not - leads me to think Tesla is simply managing the widespread rollout of #batterygate. The amount of owners equipped with OBD tools is limited, and everyone else will not be able to show their own pre-cap data
Having announced this before the cap, they will claim capped cars are now simply (better) managing normal battery degradation. Which I guess even seems credible if one is completely unaware.
Does this make sense? What do others think?
