Now been about 28 days since the first TCU "upgrade" and 21 days since the second replacement. Still not working after even an escalated case with Nissan Consumer Affairs, but I do have a case manager giving me updates every 2 days or so.
Dealership service team (NC) reported they did these replacements on 80 vehicles. Mine is 1 of 5 vehicles that continue to not work. A full refund has been offered, and is in process. If this a representative population, it appears about 15 pct of Leafs are experiencing this issue.
I happened to run into the regional Nissan tech representative and he personally took my case and will also be following up with it. I explained to him the different battery theories and the low voltage hypothesis. He seemed skeptical but he did take notes, indicating that a fault code would have resulted. We'll see what happens.
