So it seems I will be the first one, who gets a new battery pack after 4-5 years for the 40kWh Leaf.
The SOH drop did not stopped, as written above, it started to decline in bigger steps from 96.91% in just 4 days. Now I'm at 95.71%. The last 0.07% happed in one hour standing the car in the parking lot (wake up with 95.78% SOH and 100% SOC then drove the kids to school, etc, I drove about 30km, then left the car for 1 hour parking, then the SOH was 95.71%) . The temperature is currently 8°C here, so it is not the heat (battery pack between 16 and 20°C), it's raining, and quite cold.
I did not QC-d the car at least for 2 weeks, and then also only for 10-15 minutes to reach 50-60% SOC. The Hx floats around 114.18-114.20%.
So the car has 13.500km, and is about 6 months old, and already lost over 4% SOH. So 1 year = 8% SOH loss, 2 years, and I get 1 bar capacity loss. Then every year 1 bar capacity minus, so when the car will be 5 years old, I'm down to 66%, and can ask for a warranty replacement.
Seems really bad for me....
