Capacity Loss on 2011-2012 LEAFs

[DesertDenizen]

This is the full report from Scott.

Just got back for picking up my car. Here is the info the the Service Advisor told me. Surprise, surprise, it sounded very familiar.

My car test at 85% capacity remaining.

Nissan is compiling the data they collect from all 11 of the highest
loss cars that were sent to Casa Grande.

No word on when, or if I will get a copy of the tests they ran, or the results.

They completely removed my battery pack for bench testing.

My car was driven 24 miles total from drop off - to pick up.

The dealership did test for the difference between the Lowest Cell
Voltage and the Highest Cell Voltage before sending the car to Casa Grande. (When I asked for the results of that test, I was told by the Leaf Tech that he no longer had access to the data in his computer system and the printouts were sent to Casa Grande with the car. However, he did have a copy of his email to Nissan NA that had the results.)
“The highest cell 32@4010mV and the lowest cell 20@3992mV” 18mV difference

I did get my car detailed!

I still have 3 bars missing, 48 miles on the Mileage Guess-O-Meter,
with AC @ 100% charge. The car said it was 88 degrees when I picked it up, 93 when I got home.

Just got my car back too. Was told my capacity was read to be 87% which is also 10% higher then my own repeatable and cross-checked measurements.

Interesting. My first 80% charge since getting the car back was 12% *higher* than what I was getting before handing the car over for evaluation. So their 87% assessment is pretty close to my own post-eval assessment.

Please confirm that the 12% higher is the Gid count, and not some other abstract. Sounds like they swapped a few cell modules.

Sad.

Yes. Gid count.

New poster here (although I have followed site since inseption), so please be gentle. Lost a capacity bar on 8/3/12. Took it in for 1 year battery check up and told all O.K. (all 5 stars). Called Nissan (no-gas #) and was given a case # and told how to be more proactive about battery loss (very nice person but no idea about the fact how hot it gets in the Palm Springs area, hotter most days that Phoenix). I believe that Nissan has underestimated the impact of the temps on the batteries as do most of you. Info for wiki: vin#-6877, date of loss-8/3/12, mileage-9570, mfg date-6/11, purchase date-8/11, case #9137890, never quick charged or used L2-always L1 to 100%.

Decided to submit a complaint with NHTSA (no this isn't just a place for safety concerns, they also investigate defects in cars from power windows to heaters and such). I consider this issue to be a defect. If the cars in hot weather climates do not perform as well as the cars in other climates (and we were not told of this), that is a defect. As far as the comments of time left at high SOC, 100% vs 80% charge, QCs per week and all, Nissan has given me a report card (battery test) that shows 5 stars across the board. Their indications to me is that I am doing everything to spec and above (when I used to get all As in school, I usually passed the class). Complaint #10469729, submitted on 8/8/12, will be available to view in 72 hrs. I do think this a step everyone who has had capacity bar loss should take (https://www-odi.nhtsa.dot.gov/ivoq/index.cfm" onclick="window.open(this.href);return false;).

Also, submitted an inquiry to Consumer Reports on 8/8/12 with the same concerns. If this a car they are going to review, they should investigate it completely, and this is also a form I would suggest everyone fill out (http://custhelp.consumerreports.org/app/ask" onclick="window.open(this.href);return false;). This can be a little confusing (in fourth line click on Non-Consumer Reports product or services, click again for Share an experience and then click again on Defective but non hazardous).

Thanks ALLWATZ, your info has been added to the Wiki.

As much as I think complaints should be submitted (to the proper place), I don't think NHTSA is the right place to submit capacity loss complaints. When you click on "Begin online form", you're taken to https://www-odi.nhtsa.dot.gov/VehicleCo ... ndex.xhtml" onclick="window.open(this.href);return false; which has a title "File a Vehicle Safety Complaint".

If you have something to the contrary on safercar.gov or NHTSA's site that says something to the contrary, please post the URL.

New Question....For LEAF owners who charge to 80% regularly...how many miles does does your dashboard read when you first start out driving the car after the charge... 80 miles, 75 miles available? Curious to find out.

I always charge to 80%, and for the first 10 months I got 10 bars and 83 on GOM. Now I get 9 bars and 75 on GOM. I know where this is heading...

I have been getting the "11 of 12" email these past two days. I see a 3 bar loss in my future. It's been hella hot today though. I'm sure that is bringing the average GID count down.
