As I thought, the mean is 14~15K, so that shows that most are high mileage. Now combine that with the severe duty environment, and it appears that there is correlation.

I observed two days ago, while I was driving, during my first mile on my journey to work, I lost a bar (first one), was down to 11 bars, and then it returned about a mile later, and I currently have 12 bars.

Is this common?

I have 9K miles on my Leaf.

What's wrong with going by the VIN? That's more fine grained than model year, no? A LEAF with higher VIN number is younger than one with a lower VIN number (excepting the few (?) that may be in the wrong chronological order due to SNAFUs resulting from the earthquake/tsunami), while "2011 LEAF" encompasses a comparatively much larger time period.
spike09 wrote:The wiki table is also misleading as to the sum total number of cars with capacity loss. At first glance it looks like a lot more until you realize all the two bar and three bar losses are also listed under a differrent number in the one bar loss section. The seperate bar loss sections need to be combined to better show the sequence of relative loss.

For example, while you can eaasily see that DH was #3 for the third bar, #6 for the second bar and #9 for the first bar it is not easy to figure out the number of days and mileage between those events since the are not explicitly listed. So right now if you want to figure out how quickly DH lost his second bar you need to get a calender and count the days!
That's the thing about a simple presentation format such as MediaWiki's mark-up language: one can only present data one way. There is value in grouping entries by bars lost, and by individual cars.

If you want to see the data grouped by individual cars, you can certainly create another wiki page for that (but that would double the amount of work in maintaining that data). If I have access to the server, I would stand up a quick Web app to keep track of all that data in a DB.

15k is about average mileage per year. Also, scatter plotting mileage vs loss shows no significant trend. Correlation? Do the math.

I live in Phoenix. Car is parked outside during the day, in garage at night. Owned for almost a year. I shall report back if it goes back to 11 for good, would at that point contact Nissan, unless others think otherwise.

Actually, assuming a normal distribution 68% of the cars would fall in the range 10,344 - 18,178. Note that 14,100 is also the median, which means there are just as many cars below that value as there are above that value. There isn't any data showing that "most are high mileage". See statistics from DOT:

Average is 13,476 across all age groups and both sexes... very close to the 14,000 miles per year driven by the average one capacity bar loser.

leiko49 once your bar is gone call Leaf customer service and establish case number there are about 55 people on this forum that lost bar/bars from AZ, TX and CA. is your car 2011 or 2012 and how many miles on it. Is your delivery date in your signature correct?

I would recommend calling Nissan and opening up a case now, the sooner they get how wide spread this is the better. the fact that the bar came back simply means you are on the cusp. tell them you lost your 12th bar and leave it at that, the fact that it "came back" is of no significance, capacity is down none the less, IMHO.
