2011 Nissan Leaf Battery Capacity Loss: Nissan Responds
By Nikki Gordon-Bloomfield
...“We’re aware of a few isolated cases where a very small number of consumers are reporting a one bar loss. (We’re talking less than 5 units versus the 12,000 on the road in the U.S.)
Well, we are aware of twice that number, which means there must be more (unless everyone who has this problem has reported it on this forum).
Losing that much capacity in the first year seemed drastic in the light of Nissan’s previous statements on battery life, but Nissan says battery capacity loss isn’t linear.
That would have been good information to put in the acknowledgment we all signed when we bought the Leaf. That may be common knowledge among battery manufacturers, but I only heard about it in the last few weeks. I suspect this is true of most other owners.
“In general, all batteries exhibit a higher loss of capacity early in life, but then the curve flattens over time,” we were told. “Our internal results indicate that the battery will have 80 precent of its capacity under normal use after 5 years, and 70 percent after 10 years.”...
So the Phoenix owners can be confident they will only lose 1% a year for the next 4 years? Does Nissan plan to do anything for those who lose more? Are these internal results based on accelerated testing, or actual live testing of a significant number of vehicles over time?
I must say, I am underwhelmed by Nissan's response. Nothing about what they plan to do for the affected "5 cases" (who were all told this is "normal"). Glad I live in a cooler area. I would be pissed if I had bought a Leaf and lived in Phoenix. I certainly hope they are right, but from a PR standpoint I give them a D-
The brand is already slightly tarnished in my mind... but still glad I bought my Leaf and love driving it daily.
