I plan to take my car into the dealer for routine service next month, and to ask for the software upgrade. I am curious if there is any real benefit to the upgrade. I am rather disappointed to see such a large degree of battery degradation in such a short time with so few miles.
By the way, I posted this on another thread and got only one response, so I am also trying here.
First post; prompted by this request - hi, forum.
New 2017 Leaf SV, owned since 11/2017 at odo 15 mi, upgrade done on 07/28/2018 at odo 10,056 mi
Spy leaf SOH reading immediately before upgrade: 101.84%
Spy leaf SOH reading immediately after upgrade: 101.78%
Average SOH prior: approx. 103% (min/max 101.84/103.6%)
Average SOH since: approx. 102% (min/max 101.12/102.91%) Current mileage 13,000 mi.
So, yes, not much of a change worth mentioning, beyond regular degradation.
