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

This is the exact issue that I was seeing, and is not what I believe you are discussing. What happens on my car is that I average 1.1 to 1.2 miles per kw when my car is in the 100% - 70% range, then between the 70% and 30% range it drops dramatically to only 0.4 miles per kw.


watt is a unit of power -- a rate
Wh is a unit of energy -- an amount

Consumption is reported as distance/amount: miles/kWh

Would you mind reposting your comment with corrected numbers that are in the realm of possible and with a basic understanding of the units of measurement in use ?

Well, guess we are all here to disagree then. Braking is a VERY well known process and nowhere near as complicated as range degradation which is IMPOSSIBLE to test the rate of simply because of all the outside factors involved. Braking??? not so much.

So your contention that Tesla is a better company for its quick reaction to a potentially fatal flaw in its design of "basic" automobile safety if true, would have simply been a "no look, over the shoulder" luck shot.

As far as your contention that all 30 kwh LEAFs suffered massive degradation; That comment is far from true.


I never said Tesla was a better company. It's certainly easy to do good by the customer when you don't have to make money. Tesla is definitely better than any other car company at providing software updates.

And did I say ALL 30 kwh Leafs suffered massive degredation? I'm going by the graphs. Put the 30 kwh graphs aside for a minute. I don't think the 24 kwh graphs are acceptable! The only other two car companies that I know of that have had big market share plug in batteries for a long time like Nissan are GM and Tesla. I have not heard many reports at all about significant battery degradation from GM or Tesla. What other carmaker has battery degredation like Nissan?

Toyota’s PIPs sometimes have larger than expected degradation, but having a gas engine and strange protocol for when the engine launches helps cover it up

FYI, here's my change after the software update. I haven't had a chance to do much driving yet, though.

2016 SL, leased in Sep 2016 in S. California (hot summers where I am)
24k miles, almost all L1/L2 charging.
Before update: 9 bars and 69% SOH according to Leafspy
After update: 12 bars and 85% SOH

My GOM range estimates have increased accordingly. I haven't driven enough to tell whether there's a real world difference in range or if I'm actually putting more energy into the battery from near empty to full. I don't know how things will change in the near future, but I'll update if things do.

I was sure I was headed for a replacement before 2 years (which would be crazy), but now it looks like I'll have this battery a while longer.

That’s great news and closely follows the reports from others that have posted after having the update done to their cars. In fact, I have yet to see one negative report in any social media platform.

This update is a terrible turn of events for the armchair experts that have chosen to trash Nissan and their approach to battery technology. Now granted, six years ago the first generation LEAF batteries did have issues, but after 2013 and several improved battery chemistry iterations, the LEAF has shown itself to be a durable vehicle despite the critics continual whining to the contrary.

I’ve lived with three generations of LEAFs over the last seven years, and have found them all to be a reliable, trouble free vehicle, and I expect them to only get better.

Pretty sure the cheerleaders are from cooler climates. We've had two in the family in Florida and I can tell you from our perspective they suck. Only Nissan's willingness to prop the up with warranty replacements or dumping them at the end of three year leases makes them remotely workable here.
Two Volts on the other hand were good as new the day we turned them in.

And another satisfied LEAF driver who had the sense to lease an evolving technology rather than purchase (twice) and chose a brand that stood behind its a product with a warranty that set the industry standard for the product category.

Hi, There seems to be a lot on Nissan Haters on this board. Surprising because this is a Nissan Leaf Board.
With that said. I have 2017 SL with 8200K. No issues. I was surprised how fast it is and happy with the quality so far. Very Pleased so far after with a $7500 Tax Credit. $1900 Off sticker price New York State Incentive and another $10000 Off MSRP in the great state of New York last August.
I've been following the 30 KW Battery degradation issue since day 1. All the Graphs and Histeria.
I'm happy Nissan has realized there is a software issue. ( if this was Tesla some of you would be Swooning how great it was that they discovered a problem and fixed it. Also, the Telsa 3's are still coming in at twice the price. Those 35K are still not happening.)

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,
CS
