The battery issues with the LEAF are discouraging, but honestly, there's not much Nissan can do at this point. They are not going to change out the battery packs in existing cars with new and improved ones (that don't yet exist anyway) or retrofit some type of temperature management system to existing cars. Anything less than those two options will just be smoke blown up the current owner's posterior.
Unfortunately, every nuance currently from Nissan seems to highlight that every degradation is "normal", and specifically not warranteed, and if it isn't "normal", then the operator abused the car. If I were betting on the outcome, I'd say the middle ground would be what GM offered with the Volt; you can turn in the LEAF for another Nissan car.
The LEAF community has one owner who claims to be the "official liaison to Nissan North America" who apparently worked in the auto business and has Nissan execs on speed dial. If you want an insight what he discusses with them, enjoy these posting by this "leader":
1. "So far,
all of the posts on this subject are speculation, hearsay, innuendo, and opinion."
2. "In reading through all the cases,
I really don't see a problem"
3. "I have to believe that
if there was an issue, it would have been detected and solved by now"
4. This is just a problem with
"several vocal individuals."
5. There is so much confidence, he agreed to swap his battery!!! >>>
"sure, come on by, and we will put the cars up on blocks and switch them out."
6. There are as many cars with reduced capacity as there are with
">>excess<< capacity and they are both edge cases". I sure as heck haven't seen a mention of that >>excess<< case(s) !!!!
7. "If there is an actual issue with a customer's battery,
then it will be a simple routine warranty repair."
8. This is just
"battery FUD that is concentrated in some posts... Kuddos to Nissan for a job well done."
9. Hey, it's only
"17 cars out of a population of 25000 is .00068.... or in layman's terms, an edge case."
10. "for the 0.00074074074074 of LEAF owners..... investigate the myriad of options
other than complaining to get satisfaction for your transportation needs."
11. Still no problem; just charge more!!!
"'the only complaint being that they have to be "filled-up" more often"
12. "Of the fewer than 10 posters that make up the the vast majority of the posts in the 148+ pages of this thread,
I'm probably the most rationale one of the bunch."
13. It's a little battery problem because
"in the larger scheme of things this is just a fart in the breeze."
14. "8 or so posters that have been the key proponents of this...
with some interpretative data that they have been able to glean from some homebrew devices". Hey, Phil, when will you have my homebrew device ready?
15. And then the insults got more pronounced...
"Nothing smells right when you don't have a sense of smell". And then there's:
"
One of the sure signs of dementia is paranoia and being convinced that everything smells bad."
16. All of the previous statements are because
"I have a deeper understanding of how failure analysis in the automotive industry works."
17. So, it might be a software problem...
"What if this whole thing is just a SW bug that is not accurately reporting the capacity of the battery?" A bit later, that was upgraded to,
"reputable highly-placed sources suggest that a software bug". Naturally, no data to support this, or any other claim.
18. Some very specific and detailed data from most detailed person on the forum is just tossed aside with...
"your methodology does not support your conclusions". This is from somebody that really hasn't provided ANY data.
19. Another "theory" with no data to support it (nor was any offered),
"only those cars that have been driven in a severe and high-mileage mode trigger the condition."
20. The best for last, as
this post is an all time classic!!! "very vocal and seemingly
hysterical schizophrenic ADD owners ... they don't represent the vast majority of LEAF owners.... for whatever reason
are unable to deal with the situation and
would rather freak out. Speculation is rampant, and
facts are few...
fan the flames of discontent in a very
trollish manner... for many that is not good enough and
demand immediate satisfaction... Other than
assigning wet nurses to the most vocal and impatient of those that are dissatisfied, it is hard to say what more than can be done."

*******************************
Here's a summary of the issues:
November 2011 - the first known Nissan LEAF had
it's battery pack replaced when an owner in the Phoenix area reported a missing battery capacity bar on the dash instrument and reduced range. He is currently (August 2012) operating his vehicle on the second battery that is also degraded. He wishes to
get out of his lease now. He has now reported that his
LEAF was returned to Nissan August 29, 2012.
April 2012 - another Phoenix area LEAF driver
reported the same issues.
Since then, dozens have reported on this forum the loss of range / autonomy and/or battery capacity. Many have reported to Nissan at 877-NO-GAS-EV (1-877-664-2738) and been given a "case number" concerning the issue. Most of these reports are currently LEAF's from extremely hot parts of the USA, namely Arizona and Texas. However, there are now reports from other areas.
July 24, 2012 - Carla Bailo, Senior Vice President, Research & Development, Nissan Americas sends an
undated open letter to LEAF owners, and the world, about their commitment to address these issues. This letter is not present on Nissan’s main news site, where corporate news items are usually posted. Several forum readers have privately suggested that our poster
"OrientExpress" actually penned this letter, as a way to "protect" Nissan from bad press.
Nissan took between 6 and 11 LEAFs (Nissan does not officially disclose the full number,
thought to be 11, however only 6 are known on the forum) with significant capacity loss to their Casa Grande testing facility in Arizona.
August 2012 - Nissan Motor Co. said it’s hiring the senior auto reviewer at Consumer Reports magazine to be the carmaker’s new executive adviser on vehicle quality.
David Champion will work at Nissan’s vehicle testing center in Stanfield, Arizona, where Nissan tests the LEAF for high temperature environments, among other things.
August 23, 2012 - Nissan
sends out a survey to owners asking, among other things, how much range loss is acceptable.
September 2012 - Awaiting official word from Nissan as to the results of their studies, and their intentions going forward. Many have expressed concern that if the results are "everything is normal" and try to "explain things away", aka "whitewashing", that those affected owners will then have the resolve to move forward with more robust methods to address these issues.
********************************
Why Did Nissan Develop an EV Battery? "A battery that can control its heating without a cooling mechanism is also longer lasting, since the biggest cause of a
battery's lifetime being shortened is overheating."
A recent
study by Pikes Research with U.S. Department of Energy data shows,
lithium ion batteries (like those in the LEAF) exposed to hotter average temperatures lose their ability to store energy;
the hotter the temperature the faster they lose their storing ability. So BEV owners in Phoenix will likely be looking to replace their batteries faster than owners living where the thermometer doesn’t often reach 110°F.
Nissan specifically DOES NOT WARRANTY BATTERY DEGRADATION (capacity losses), however, changes to range / autonomy are not specified as a result of battery capacity losses. Nissan's sister company,
Renault, does warranty the battery for 75% capacity with a virtually identical battery of four AESC cells per each of 48 modules. General Motors also offers this protection with a far more robust Volt battery pack, mostly because there are emission control considerations (the gasoline/petrol engine will run more if the battery degrades). NOTE: Volt battery uses about 60% of capacity, LEAF uses 93%. Volt battery is liquid cooled, LEAF has no battery cooling.
“
Thermal management of lithium-ion battery systems is critical to the success of all-electric vehicles because extreme temperatures can affect performance, reliability, safety and durability,” says a Ford press release.
“Extreme temperatures impact a battery’s life and performance, making it crucial to have an effective cooling and heating system to regulate temperature for these demanding applications,” said Anand Sankaran, Ford executive technical leader, Energy Storage and HV Systems.
Some owners suggest that the
battery degradation is contingent on "Arrhenius Law" formula of double the degradation per 10C rise in temperature. So, a 0C battery has X loss per hour, then a 10C battery has 2X loss per hour, 20C = 4X, etc. Here is
a graph of this formula on various US cities.
Some owners are
making plans for legal help or
class action status. Some Phoenix area
attorneys have expressed interest in suing Nissan over these issues. Please PM "opossum" and "Azdre" for more information.
At least one LEAF owner received a solicitation from
one of the law firms actively looking for clients on these matters. Here is a thread
discussing law suit issues.
The forum's most dedicated data collector, and a reduced range Phoenix LEAF owner, has started
this thread concerning his data driven findings.
Here's a
first hand account by an owner who met with Nissan engineers in May 2010 (well before the car was released) at the Arizona Testing center, "They did admit that the high temperatures reduced the mileage by 10 to 20%."
Some have suggested that this must be a software issue, and further that
"high up" Nissan folks think so too, instead of a battery issue (by Nissan's use of 93% of the capacity of the battery, and not using a temperature management system on the LEAF), however another data driven LEAF driver with capacity and range reduction says that his low serial number car (185) with the original firmware
went through last summer in Phoenix without issue, and now has capacity / range issues this summer with the same firmware. The same was expressed
here.
Some owners have sold their purchased LEAF,
only to lease a second LEAF or other EV, as a method to mitigate any impact to value of the vehicle because of battery capacity and range reduction.
Going to a Nissan dealer has thus far resulted in a response of "all is normal" with the battery, regardless of the range / autonomy reduction and/or battery capacity degradation. Also, any battery report conducted at a dealer, and the subsequent results given to a consumer, will likely have "5 of 5 stars" in every category, regardless of the range / autonomy reduction and/or battery capacity degradation.
Please read the comments posted on this "autoblog" website in an article titled
"Is the Nissan LEAF Battery Pack under Engineered?". These comments were made almost one year before a single LEAF was produced, and suggests Nissan seriously made a mistake selling the car in hot environments like Phoenix and Texas.
Tesla CEO Elon Musk, in 2009, well before LEAF was released for sale
rips on Nissan's battery technology, and says it's "primitive" without a temperature management system. PLease read the comments on this article, also. Very well thought predictions that this would not end well for Nissan, and the greater electric vehicle community.
Naturally, the Nissan legal department made clear the battery capacity is without warrantee, but as we know,
consumers have been sold a car in hot places like Phoenix that the manufacturer knew would NOT survive the heat and did NOT tell the consumer of these shortcomings.
Some have suggested that manufacturers should not be allowed to market any other range figure except what a standardized EPA test has determined. Also, to include the effects of local climate on batteries that are without any method to protect from ambient heat.
The US government's National Highway Traffic Safety Administration (NHTSA)
has an presentation from Nissan concerning their theory on how the battery handles heat (see slide 12 of the presentation). While I am not suggesting that this may happen, if the NHTSA orders a vehicle recall for a
safety defect, the manufacturer has three legal options for making good on the order. The manufacturer can:
- Repair the vehicle free of charge (this is the usual remedy you see offered for a vehicle defect);
- Replace the vehicle with an identical or similar vehicle that is free of the defect; or
- Refund the purchase price in full minus a reasonable allowance for vehicle depreciation.
*********************************
If you are experiencing
reduced range / autonomy issues, and/or your dash battery capacity instrument is
missing one or more of its twelve bar segments, here are some suggestions to pursue:
1. Report to Nissan at 877-NO-GAS-EV (1-877-664-2738) and get a "case number" concerning the issue
2. Report to
the National Highway Traffic Safety Administration "Office of Defects Investigation" and get a Confirmation Number (ODI Number) concerning the issue. Address: 1200 New Jersey Avenue SE, West Building, Washington, DC 20590, 1-888-327-4236 or 1-202-366-0123. Here is a NHTSA
presentation about electric vehicle safety from Nissan. Check out slide 12 about heat affects on lithium batteries.
3. Report to
Consumer Reports. 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.
4. Report to respective Better Business Bureau.
Here is Arizona BBB and
here is California BBB. The Council of Better Business Bureaus, Inc. is at 4200 Wilson Boulevard, Arlington, VA 22203; 1-703-276-0100
5. Report to your
State Attorney General’s Office
6. Report to
Center for Auto Safety, 1825 Connecticut Ave, NW, Ste. 330, Washington, DC 20009-5708. You may send them a letter sharing your experiences with them. Should they have any information on your particular automobile, they will forward it to you, along with helpful information and advice within 10 days from date of receipt of their letter. They ask, but do not require, a $.60 SASE to help keep their costs down.
*****************************
Here's some options on how to dispose of your car, should it no longer meet your needs, or you are concerned about loss of value concerning loss of range / autonomy. First, you must determine what your end result needs to be:
1. Wait for Nissan to acknowledge there is a problem, devise a plan and implement a fix to your satisfaction.
2. Nissan may
take back leases under certain parameters.
3. Sell the car. CarMax has been a good place to start.
3. Use your state's Lemon Law. It may be prudent NOT to address battery capacity, as that is specifically not covered by warranty.
4. Hire legal help for individual (tort) suits.
5. Join a class action suit.

Nissan Corporate Contacts:
Mark Perry, Director of Product Planning for Nissan North America. On August 3, 2012, he was reported to have said, "We've also been very transparent in making sure people know that battery capacity will degrade in very high heat – for instance, if the cars
sit out in 110-degree heat for five hours a day." He was also quoted as saying sometime before January 25, 2010,
"We don't need thermal management for the U.S., but we are looking at the technology for Dubai and other locations like that.... We've gone on the record saying that
the pack has a 70 to 80 percent capacity after 10 years."
Here are some average temperatures:
........................Dubai............................................Phoenix........
