Again, the pipeline parts for the 2011/2012 are manufactured in Japan, with an apparent limited supply warehoused in the US. It makes absolutely no sense to keep shipping them from Japan, where the same unit is still installed in ALL new LEAFs, when the design has been found to be deficient for our environment. I agree they'd like use the ones warehoused here, but it makes no sense not to use the 2015 packs once that limited supply is exhausted.
