He lives near Phoenix and here are some examples:
On June 18, 2012, he posted a screenshot of 111 F temp for Phoenix from a weather app.
On July 10th, he posted a 104 F pic from his car and said at 9:40 pm, it's still over 100 F.
On Aug 5, 2011, he posted a pic of his car showing 100 F at 9:17 pm.
On July 2, 2011, he posts a pic of his car showing 117 F.
The above Phoenician Facebook friend posted some temps yesterday.

On June 28, 2013, he posted a pic of his Prius showing it's 117 F outside at 4:07 pm (Pacific time, I believe).
On the same day, at 10:26 pm, he posted his Prius showing it's still 100 F outside at 10:15 pm, saying it was 2.5 hours after sunset. Also said it "Was still 108° in Downtown Phoenix when we left there at around 9:40pm!"

Crazy!

+1. Given that the capacity warranty is only good for 60K miles, you might as well put off replacing the pack if you can. Granted, there's the risk of getting a refurbished pack with less than full capacity, but then again, if you get a new pack now it will have degraded significantly by the time you reach 60K miles.

Plus, in the meantime, you might be able to attain the dubious distinction of having the LEAF with the fewest capacity bars!

Just lost my first capacity bar this morning. My 2011 LEAF has 35,365 miles, delivered 8/25/11, located in South San Jose (Almaden). The beginning of the heat wave yesterday in San Jose may have been the tipping point.

Had mostly charged to 80% once per day (weekdays) for the past 22 months, but started charging to 100% during the past 2 weeks. On weekdays, the car has sat in a shade in a car-park in Sunnyvale, CA. Varied between 80%/100% on the weekends, and only FC when the ambient temp is below 70F. Avoided FC in summer, and only FC once per month in the other 3 seasons for the past 22 months.

Car is mostly at 5 temp bars for the 1st 3 seasons, but edges to 6 bars in the late spring and summer. Only saw 7 bars once, and only when I FC at 74 degrees (would never do that again).

Garaged the car overnight for 3 seasons, but starting this summer, started parking the car outside, overnight, and used the portable trickle charger versus Blink to keep the battery cool, or cool it off. Kept the ICE outside of the garage overnight as well, as that car really heats up the garage (probably cooking the LEAF battery). In hindsight, I probably should have done this last summer--but who knew until last year that the battery would degrade quickly from heat?

Been reading MNL for the past 2 years, and had been paranoid about keeping the battery cool since the news of battery degradation came out a year ago. Haven't posted previously, but now I got to, given the first lost capacity bar.

Ironically, I lost the bar today, right before my appointment with the Nissan Dealer (for the 2 year annual battery report and P3227 software update). Curious to see what happens after the appointment.

Car has been great otherwise, and we never expected to use it as our primary car--but it definitely is used as our primary car. We've gone just about everywhere in the the SF Bay Area in our LEAF.

Can someone add me to the Wiki page? I'm curious to know how many other folks in the SF Bay Area have lost a capacity bar.

Sorry to hear, you are number four or five, by my count anyway. The first documented case was Fabio. The wiki is located here. Please consider getting an ELM327 bluetooth dongle and a dedicated Android phone or tablet. That could remove some of the guesswork, and facilitate better utilization of the remaining battery capacity.

Yes, absolutely, even if some data was missing. It's still early in the adoption curve of EVs, and this type of documentation can help others in your area.

@ surfingslovak--thanks for sending me the link to the wiki. I just updated the wiki with my information. I don't have the OBD dongle yet, but a fellow LEAFer at our recent SFBayLEAFs meeting last month did plug the dongle to my car and gave me the results. 85.2% capacity was the read at the time. I'll either get the dongle or go to next month's meeting to see what has changed.

I thought Nissan had made it clear that if you are already down four bars then you are eligible immediately, upgrade or not. As you and others have said, the reason for waiting would be if it improved your odds of having a better battery when you reach 60K miles. That's a gamble, but I would also guess that if you switch soon you have a good chance of getting a new, or like-new battery. If you wait until next fall, however, and let's say you have say 48K miles by then, Nissan could calculate that you only need enough to go another 12K miles in mostly cool weather and give you a 10-bar, or even 9-bar battery.

Lost second bar today. It is now a race to the warranty cut off.
Just had the 24 month battery check so Nissan is well aware of the progress.
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.

This is still an assumption, no? Has anyone actually received the letter which was supposed to formally announce the capacity warranty?

Got the letter in today's mail. Will scan it a bit later, if nobody else gets theirs and the group wants to see it. I don't even have time to read it properly myself just now.
