Nissan would not offer a fix if it wasn't legit. Come On people. You think Nissan would open themselves up to a class-action lawsuit by rebooting software after their batteries weren't lasting long. Really?
I m100% confident this will show the batteries are good. Remember Only a handful have failed over the warranty time period. Do the research as I have.
After I get the Reboot I will wait the 7 years and another 91000 to see how the battery hangs in there.
All The best,

I love my 2012 Leaf SL from the perspective that it's reliable as long as I'm operating within the known range. (8 bars, 55-60 miles range.) I got it for a song. $6k, used. No way I could get into a BEV without these Leafs having such terrible resale values thanks to the degrading batteries. lol.

Regarding Nissan. I also own a Nissan Versa. Transmission (CVT) started crapping out on it within 15,000 miles. Took it to the dealership 3 times over a period of time trying to get them to fix the issue. They finally replaced the CVT at 45,000 miles when it was nearly impossible to drive without being a hazard on the road due to inability to accelerate. Until that point, it was unsafe to drive only periodically. They applied a "software fix" before they replaced the transmission. A service call was issued for these nationwide. All it did was change the behavior of the transmission to make it behave more like a traditional automatic transmission and less like a CVT. Anyhow, fast forward, our transmission is acting like it did before, so failure is imminent. Hopefully I can get my standard range Tesla Model 3 before then to replace the Versa. Just do a google search for Nissan CVT failure, you'll see all sorts of class action lawsuits, typically Nissan extends the warranty to 100,000 miles as a settlement to that particular year and model but not others.

The behavior of Nissan with the Versa, plus the initial denial of problems on the 2011 and 2012 Leafs which required a class action lawsuit (just like with the CVTs on their ICE cars) is why I don't like Nissan. Back in 2010 I was rooting for Nissan and Ghosen, as I thought they were committed towards progressing BEVs with the Leaf and others, but the constant denials of problems on their part due to poor engineering, whether it's the CVTs with extreme failure rates (where it is warm) and the Leaf battery problems changed my opinion for the company for the worse. I'm unsure that Nissan could ever have me as a customer again.
Pulled the trigger on going EV on 10/2016 with a 2012 Leaf, and a Tesla Model 3 reservation expected to receive in June 2018.

Hi:

Any of you that did the software fix noticed any changes on the regeneration braking or changes in the fast charge speed (kind like a rapidgate issue)?

I would be interested to hear the answer on these questions also,
- Regen affected? Less?
- Is DCQCing slower? What Amp rate to what percent full?

Re: Nissan issues software update to solve 30 kwh battery issues

Just over three months ago I installed Leaf-Spy on my phone. At that time, I had readings as low as AHr = 68.17, SOH = 85.77%, and Hx = 80.92 on my one year old 2017 Leaf with just under 6,7000 miles. Now three months later the readings are AHr = 75.776, SOH=95.34, and Hx = 88.54 at 8,500 miles on the odometer. I have been charging the battery to 100% more often, and have taken the car for longer drives. I am wondering if this dramatic change might be due to the so called software error. In any case, the recent values are encouraging, and are continuing to improve.

Does anyone here have any idea what is going on?

The bms stats tend to go into "hibernation" during the winter may have remembered some low readings from previous.
With the warm weather , the stats go up as the battery can store/regenerate more power than when cold.
Also the car (battery) likes to be driven , just try to avoid those 10 temperature bar DCFC successive charges :(

I've had the fix for 5 days and haven't noticed any difference in regenerative braking. I mostly drive in B mode, but am occasionally in D mode some of the time. No quantitative comparison, just my impression.

I have only L2 charged, and that's been the same before and after.

How long ago did you have the SW fix installed?

How often do you take LEAF Spy readings?

Am I to understand you drive about 600 miles a month?

I have not had the sw update. I was just wondering if what I am seeing is due to a software problem.

I take readings almost every time I drive. And yes, I drive about 600 miles perl month. I am just curious why I have since such a large increase in three months. By the way, I am pleased that the readings have gotten better.

Re: Nissan issues software update to solve 30 kwh battery issues

So, had the Software update this morning. Not much to report yet. We are about 55 KM to the dealer. Arrived at the dealer with about 72 percent left after charging to 100 overnight. They did the update and then put it on the charger as I went off to the mall to kill time. Typically a full battery reads 184 to 188 KM for us. GOM is actually very acurate for our type of driving. Most speed limits here are 90 KMH and the route has some 50 and 70 KMH stretches as well as a short stretch of maybe 10 km at 100 KMH. Hilly windy route but starts and finishes at same altitude. I always drive at the speed limit and on cruise. Temp set on auto at 24 degrees.

After the update GOM read 196 KM at 99 percent. Arrive home with 75 percent and a combined GOM and trip odometer of 202 km. This is probably a little better than normal but not much. Maybe 6 or 8 KM better. So what did I notice. Well, the biggest change was that 4 bubbles of regen were available at 95 percent as opposed to 90 percent. Other than that pretty much the same.

We have a 450 km trip coming up in a few weeks that will involve a couple fast charges. I'll report in then on any changes.

Numbers generally improve when car is driven further between charges if period is relatively short. Why this happens is somewhat of a mystery since there is no science behind it. imho, its likely the LEAF pack simply loses track of the pack's status and regains it when the car is driven to a low SOC and recharged. This allows the BMS to do a sort of recalibration. The ideology that exercising the pack will make it stronger simply has no physical basis in reality.

The opposite is also true. Don't drive far or spend several days to drive off a single charge and the numbers start dropping. Again, no real reason why this would happen other than simply poor accounting processes by the BMS.
