If Nissan expected only 5 years of battery life why they said nothing about this when they sale this car to us???
You bought from a Nissan dealer. In the US (I can only assume you are from the mention of the 877 number and usage of $ since you didn't update your info to include your location), in most states, automakers cannot own dealerships due to state franchise laws. Google for tesla franchise laws
to get an idea of Tesla's legal battles.
As for 5 years or battery life or whatever, your battery still works. Whether or not it is still suitable for your use cases depends on its condition and number of miles of range autonomy required on a single charge for how that person drives. My commute's under 13 miles each way and I have free charging at work. If I fully charged at home and a work, I could be down 11 bars and still make my commute w/my Leaf.
Right now my 5/2013 built '13 Leaf still has all 12 bars but is getting close to losing 1, from Leaf Spy stats.

What did the warranty say? If it didn't say it covered gradual capacity loss or capacity loss at all, the onus was on you to read it and understand what you were buying. It's not the 1st time a salesman has made statements (sometimes misleading or incorrect) to make a sale.
In my opinion, this battery is a deffect and should be cover by Nissan. Do I have to be an expert in this car to understand all aspects of degradation before to buy because Nissan lied to customer with no providing full information for the battery degradation?
Read the terms of the factory 8 year/100K battery defects warranty in the warranty booklet (also found at https://owners.nissanusa.com/content/te ... ooklet.pdf
) and whatever extended warranty you may have bought. Also see http://www.mynissanleaf.com/viewtopic.php?t=13192
Again, it's highly unlikely the dealership you bought from was owned by Nissan, so Nissan didn't lie, an independently owned dealership person may have lied to you.
Nissan, the company unfortunately has not been forthcoming in general about battery degradation on Leafs. As I've pointed out at http://www.mynissanleaf.com/viewtopic.p ... 30#p469608
and elsewhere, Mark Perry (who retired in late 2012 from Nissan) asserted in March 2012 that after 10 years, you'll have about 70 to 80% capacity remaining which turns out be WAY off for the batteries of the time.
There were other claims, like http://www.mynissanleaf.com/viewtopic.php?p=359497
I am not agree I have to do research on electrical car before buying because two years ago there was no much info for Nissan Leaf battery problems.
Sure there was, from a degradation point of view.
TonyWilliams ran a range test in September 2012: https://web.archive.org/web/20130115102 ... p?p=228326
. There were 1 to 4 capacity bar losers when the Leaf had only been out ~21 months. Blue494 was the worst at 4 bars down. http://www.mynissanleaf.com/viewtopic.php?f=30&t=8802

was from Oct 2012. There also a Phoenix townhall from Jan 2013 in the page 2 summary page.
People have been talking about capacity loss since May 2012, if not earlier.
was started to discuss battery replacements in 2013. Looks like the earliest I can find in there is a replacement in July 2013: http://www.mynissanleaf.com/viewtopic.p ... 58#p313358
Also, YEARS ago, Stoaty + some other put together an aging model based upon what they knew of the '11 and '12 Leaf batteries of the time. It's at http://www.electricvehiclewiki.com/Batt ... ging_Model
