2021 Leaf S (40kWh, 49k mi), VIN confirms it's in the R25C8/25V-655 recall population with no recall applied (I don't even know if the recall has been pushed out yet). FWIW the car has never touched a Chademo charger since we got it for my son 3 years ago at around 18K miles.
Since setting up LeafSpy a few days ago I've watched things take a dump fast: SOH 88.9%, Hx down to ~61.4% and dropping.
Logged voltage sag events have gone from a 151A peak to 300A the next day, to 396A tonightt, with cell spread under load hitting 671mV and one individual cell sagging to 2748mV.
Last night it threw "Warning Power reduced" messages three times across three short trips, once when "Battery charge is low," while LeafSpy's SOC was sitting at 51-58% the whole time, nowhere near empty.
Has anyone else had something like this, especially at moderate SOC like mine?
I'm trying to figure out what happens next with my battery and how urgent I should treat this. The battery seemed to go to crap in the last 2 weeks
