I recently bought a 2013 Leaf SV with 23,000 miles on the odometer from CarMax, and returned my nearly identical leased '13 Leaf to Nissan (the only major difference being that the leased one had a QC port, which I will miss, but not enough to regret too much, hopefully, since now I have no monthly car payment to make).
The issue is that at 100% charge the guess-o-meter estimates only 77 or 78 miles of range typically, which is several miles less than my leased one normally displayed. The 'new' Leaf displays all 12 capacity bars, while the old one had dropped a bar, I expect because I used QC very often and regularly, even through hot summers in L.A. - battery temps got very high too many times . So I expected the 'new' battery to be a bit healthier than the old Leaf's, but in fact the opposite is true, and that's borne out by my driving experience, not just the guess-o-meter. By the way, the 'new' one was from Georgia, not the desert, so I wouldn't think that would be a big factor.
I don't have a LeafSpy device, but would like to know what LeafSpy would report. At first I wondered if I might have a vehicle that was tampered with, perhaps the capacity bars were reset fraudulently. If I could prove that, I believe CarMax would make it right. The vehicle still has factory warranty coverage until April or May of 2016. I have fewer suspicions about tampering now, but still wonder what is going on with the battery.
If anyone would be willing to share their LeafSpy and knowledge of its secrets, I'd be happy to drive to you or a location you choose to learn about this car's battery, at your convenience. Also I'd be happy to compensate you reasonably for the time, trouble and your 'expertise' with LeafSpy.
Any other alternative thoughts, or suggestions on how I should proceed, would be welcomed! Thanks!
