I'm looking for advice on how to proceed with a problematic battery capacity situation.
I recently purchased a 2017 SL through a wholesaler / auction process for which I wasn't present. The car had <3K miles and 12 bars showing. A call to Nissan confirmed the 12 bar status and the warranty was still valid. When I received it, it had ~10% charge. Once I charged it (to about 85%), the first red flag was that the GOM range value was less than the percent charge. The second red flag was when I received the title and saw that the single previous leasee lived in Arizona (which was not the location of the auction). The third red flag came when I charged at a station and got ~50% charge increase with 10 KWh. I've driven it about 200 miles, and it is still showing 12 bars, but the GOM has been showing consistently less range than the percent charged, despite the economy being at ~3.3 mi/KWh. I recently purchased an OBD-II device and used LeafSpy to obtain a more detailed report on the battery. The initial reading shows:
AHr: 58.29
SOH: 73.34%
Hx: 72.13%
369.76 V
Obviously, these numbers are troublesome, since they suggest my capacity is at ~21.5 KWh. This is also in line with the GOM and charging station experiences. What I don't understand is how the battery capacity could be in such bad shape with 12 bars showing. From what I've read, the BMS can be reset, but wouldn't I see strange numbers through LeafSpy as well?
Either way, it appears I've been tricked into purchasing a Leaf with a heavily degraded battery capacity.
Does anyone have suggestions on how to proceed from this point?
What further data should I be collecting?
Even by the LeafSpy numbers, I'm not in the 8-bar territory yet. Do I have any other recourse, considering the faulty/tampered bar display and Nissan's confirmation?
I haven't been able to find a thread with a similar problem, but please point me to others that might be related/helpful.
Thanks in advance!
