Reset of lithium battery controller (LBC) and/or battery replacement by Nissan does not reset DCQC and L1/L2 charge counts (at least it did not on my 2011 when the battery was replaced in October 2013). How many miles on the 2012 car? How many DCQC charge counts? I wonder if multiple control modules were replaced without following proper procedures in Consult 3+ to copy data from old modules. Did the dash display show all 12 SOC bars (long bars) after the L1 charge? If 12 SOC bars, but only 83% SOC on Leaf Spy, then something is wrong.
