Did this all come to you in a dream, or are you hearing disembodied voices ?

Ok..mine received the update today. Before getting the update, it was like this:

After receiving the update, this was the result:

The curious thing is that the % indication on the display was the same. I then proceed to the nearest working PCR (it was on the highway, about 20 km of distance. I arrived there with 50% of the battery and the temperature was about 32ºC (i made all the possibles to heat them up the most). This is how the charge went:

Maximum speed up to the 76% on LeafSpy (80% on the car display) and then it started reduced. This was allready the normal behavior before the update, so the only changes are the SOH :D :D

Jbuntz, sorry if I missed your explanation somewhere earlier, but if you were at 8 bars didn’t you qualify for a new battery? Were you required to do this SOftware downgrade (I mean Upgrade :o )


I missed the cut off by a couple of weeks :(


There was no cut off. The reality is Nissan was getting degraded packs and upon testing, they were well over the 8 bars required for replacement so the people who did get new packs, got them thru a Nissan SW error. not from true degradation.



My battery has still prematurely degraded even after this update. 87% SOH on a two year old car with 28k miles is unacceptable. Lease is up in February so not really a problem for me. Had I purchased it would be a different story. By comparison a 2 year old Tesla with 28k miles would probably have only around 2% - 3% degradation. It baffles me that there are members on this forum that still defend Nissan's crappy batteries!

It is because a large group of people with your opinion have washed their hands of Nissan and no longer post here. You are reading a dying forum with a distilled viewpoint fueled by motivations other than technical merit.

Your experience isn't the same as mine.

Your expectations also seem to be rather different.

This forum seems to be a mix of disgruntled Leaf drivers, Tesla Trolls and a few oddballs. Hardly anything to write about, when your Leaf is doing just fine. Boring just commuting with no issues, day after day.

Fortunately there are a few states in the US where the need for a BMS is neutralized by a cooler year-long climate. These include OR, WA and AK.

Even a few months of excessive 90+F heat is enough for significant premature degradation.

I'm keeping my 2018 in an A/C-cooled garage with an average temp of about 72F. I think I'm still looking at 3-4% degradation per year.

I rarely read or post here after giving my Leaf to my nephew and buying a used Tesla Model S85 almost one year ago. Don't think about these issues any more as my Tesla has no identifiable further battery capacity loss. Also, the rated range is very useful. I find that if I have a rated range of 200 miles (an 80% charge) and drive 100 miles at 65 MPH the rated range is now very close to 100 miles. Passenger air bag was replaced under warranty (one of the millions under recall) by a Tesla technician who came to my house. The only other expense I have had is getting the tires rotated once. The Leaf was a great starter BEV, but can't hold a candle to the Tesla.

Ah, isn't it a little difficult to estimate your annual degradation rate, based on your very limited experience so far?
