Can anyone claim LEAF battery degradation at even fewer miles?
I have a 2011 Nissan LEAF with 17,820 miles. The car is in nearly new condition, except for the battery. The GOM is at 7/12 bars; the SOH is 50.50%; it has 128 GIDs. Ten months ago, it had 16,392 miles, the SOH was 62.77%, and it had 173 GIDs.
In the car's entire vehicle lifespan (~13 years so far), it has had ONE quick charge and 1228 L1/L2 charges. The average miles driven between charges is 14.5 miles, so the depth of discharge was not severe (even for such a small battery).
Rightfully, the car should have been subject to a Nissan warranty replacement, but the miles driven during the warranty were small enough to defer the battery degradation until after Nissan could wash its hands of their design mistake.
The alleged $5,499 Nissan battery replacement that @BBrockman (Brian Brockman: Vice President, Nissan Communications, U.S. & Canada) trumpeted on this forum is complete vaporware IMHO. The local Nissan dealer wouldn't quote me a price over the phone, telling me that I would have to bring in the vehicle. After I did just that and they kept the vehicle for three days, they still told me there was nothing they would do and just gave me the Nissan consumer affairs phone number. The excuse I get from Nissan Customer Quality & Dealer Network Development is that there are "supply chain issues"; they are being particularly hostile to me because I didn't buy the vehicle from a dealer.
I've been collecting data during my ten months of ownership, and you can see some of it in the graphs further below. The vehicle is configured to charge to only 80%, and I try to avoid more than three dots (~20kW) of motor consumption so as to moderate the battery temperature.
Other degraded battery symptoms that I'm encountering are:
1) The car has the infamous intermittent touchy brake pedal problem where it goes from limited braking to tons of braking at lower speeds at a particular point in the brake pedal travel. (The result is herky-jerky driving in stop and go because there is too much braking, so I let ever-so-slightly off on the brake pedal, but then there is too little braking to safely stop in time, so I have to press the brake pedal a little harder again, which again gives too much braking.) The dealer bilked me to apply the NTB12-086a software update. The software update hasn't changed things significantly.
2) There is no regenerative braking (as confirmed by the energy screen information showing current battery absorption of power) until the vehicle is going less than, say, ~15 MPH. I suspect that it may be part of the cause behind #1.
3) When I infrequently try to override the timer and charge to 100%, the trend is for it to terminate earlier and earlier (as low as 85% recently).
My fingers are (wishfully?) crossed that the battery degradation slows down enough that I can get enough short journeys that it won't have been a complete waste of both: a) my money, and b) the environmental cost incurred by Nissan by building the car in the first place.
