I lost my first capacity bar today. Only 6,771 miles. Manufactured 6/21/2011, took ownership 7/25/2011. I charge to 80%, never did a QC and charged to 100% exactly three times. The 100% charges were done just before I drove so the car spent no time sitting with a full charge. Never drove below 2 SOC bars. Received all 5 stars at my first annual, which was on 7/25/2012. I only charge every other day or so. I start to charge at 6 in the morning and usually leave around 9 so my Leaf doesn’t even spend much time at 80% charge. My Leaf has spent 90-95% of its time between 3 and 8 SOC bars. My long term average is 5.7 m/kwh and I drive on the frontage roads, not the highway, so I never exceed 45 mph. Exclusively in Eco. It is parked under a carport. I am out in the desert so there is no blacktop or concrete, just dirt. Tucson averages about 6 degrees cooler than Phoenix. Summer temp bars are usually 6, I have driven (but not charged) with 7 temp bars for short durations, but not many times. My new case # is 9497015.
Added to the wiki. Thanks for the full set of info! Makes it much easier :D

Did i read that correct. Nissan is stating only 140 cars in the US have lost a bar. We have 96 people listed here. Are you kidding me. Every known bar looser is on this Forum. I call BS , I hope someone that sues will get all the Carwings Data from the US and spill the beans. This company is just trying to Kill the EV movement.

No, Mark Perry was quoted as saying "less than 100". One of the recent articles in greencarreports.com or insideevs.com (can't remember which) stated that they had (? inside) information that was the number.

This is very unfortunate. You seem to have treated your car very well and not stressed the battery at all. What are the night/early morning temps in Tucson? I live in a somewhat similar climate area in the SF Bay area (East Bay) where we experience high day time temps but cool nights. My charging is done with an end timer at 0700 in the morning. So my charging usually takes place in the wee hours of the morning. I have certainly stressed the battery more than you have - 55 to 60 mile round trip commute and speeds up to 55mph, 60mph on downhills. I try to limit myself to 20kW output for most of my driving. I have charged to 100% once to thrice a month, never QC. Yesterday I got 5.6 miles on my 10th bar (80% charge). The car has around 17,500 miles on it with all 12 bars intact. I think you have a defective battery since your climate is not that different from mine and you have taken better care of your battery than even I have. That too with only 6771 miles! Hope Nissan takes care of this issue.

Florida: 2012 Nissan Leaf added to the missing bars club 7467 miles. Leased began Labour Day 2012. This morning checked my overnight charging at it showed 80% charge and 9 bars.

I did not baby this car because I needed to use it to travel a 45 mile each way commute. So it spent June and July having 100% overnight charges on 110v, with another 100% charge at work on 240v. On those days that I couldn't charge for 4.5 hours at work, I charged at another station for several hours to make it home.

Just sent a note to my dealership. Will send the photo when I get home...

That isn't a missing capacity bar. However, it does appear to be a warning that actual capacity bar loss may not be too far off.

It's probably the number of "reported" cases. As everyone can see on the wiki, only about half of the people with losses have officially reported those losses to Nissan and received a case number. For those who don't frequent our forum, it's probably an even larger number of people who know they have losses but haven't called Nissan and gotten a case number.

If that's what it is, then it is extremely disingenuous!! NISSAN KNOWS EXACTLY HOW MANY OF THE LEAFS WHICH HAVE HAD THEIR ONE-YEAR BATTERY TEST HAVE LOST BARS!!

I believe that this was the case in previous press releases As well, and only the number of reported cases was considered.

There are a few of us that lost a bar after the 1yr test. The test at the two year mark will be an eye opener.
I have not called for a case # because I am not certain my situation is unreasonable or completely unexpected.
I did not ask to be on the wiki or make any stong complaints. Just expressed some dissapointment.
Certainly there are far worse cases than mine that do need to be looked into.
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.
LEAF traded at 45,400 miles for a RAV4-EV
RAV4 traded in for I-Pace Dec 2018
