In reality I am too. But when all these reports of early degradation started surfacing the pattern was instantly recognizable to me.webeleafowners wrote:We don't have leaf spy so can't contribute data here but am curious as well on how build date affects this. Our 2016 SV is build date April 2016. We live in a milder climate but do hit 38 C in the summer. Lets say 100. We operate in the 7 bar range for a couple months of the year and have seen 8 bars occasionally after multiple fast charges on longer trips. We have noticed little Max range change on either the GOM or real world. Would you speculate this is a result of climate or build date. Probably a third less mileage on our car compared to the other leaf owner. Is there any evidence that they started to build the new 30K packs different after a certain date??
What we should have been seeing is incremental improvements in pack performance from day one. We have but with two glaring hiccups.
#1 early 2013 builds coinciding with opening of Symrna TN battery plant. Later 2013 builds up thru 2015 the steady improvement continues.
#2 2015 builds of 30 kwh packs introducing various changes including electrode content. Later 30 kwh builds seem to be doing much better. On this; there is a case that "can be" made that the later 2016 packs are simply not old enough yet. I dispute that. We have 2015 30 kwh packs that starting showing up 8-10% degradation via LEAF Spy readings in just a few months including LEAFs in Oregon. Now parts of Oregon can get pretty hot but its not Phoenix, Las Vegas or San Bernardino County no matter how you slice it.
In both cases, a major process change was involved. In both cases (so far) a sudden and significant improvement followed immediately afterwards. I guess we should hold off on this convo until the later 30 kwh packs have more miles and months under them. As far as evidence of any process change to correct the issues? Not sure why anyone would expect Nissan to come forward with that information.
QC issues are fairly common in any highly complicated build like cars and its by and large industry policy to not divulge these types of things to the public when there is no requirement for them to do so.
Anyone here buy a 2013 Ford Escape? You know, the year of the big refresh? If you did, you know what I am talking about. If you didn't, DON"T!
