12V battery went "bad" after VCM recall?

[dvakata]

2019 LEAF with no issues for last 4 years and I decided to give it a go for latest recall Nissan sent me. Recall R23A6 R23A6 - 2018-2023 Leaf Vcm

So dealer did a SW update overnight (server wasn't available). After that 12V aux battery no longer holding charge. I went back to dealer, they did a test and suggest battery is up for replacement - PERFORMED AVR TEST. BATTERY TEST FAILED. 280CCA/410CCA

Is it common to have battery failed after just 4 years? Sounds very strange to me that it failed immediately after this recall.

Welcome. If you live in a Hot or Cold climate, then four years isn't unusual. It would be a little soon if your climate is mild. I agree that they may have managed to run the battery down during the update, but that may be hard to prove.

Hard to prove and also a death blow to an aging SLA unfortunately.
If you plan on keeping your Leaf until the wheels falls off, consider going the AGM or LiFeP04 route. More expensive, but a lot less issues with battery life and 12V car computer issues if the SLA has a low sagging voltage during extreme temperature times.

Toronto. And thats where I'm surprised, my Mercedes ML 2012 still running on original battery, while all electric Nissan need a new, aux, but still, battery. Questioned design

I was no choice to pick replacement battery option from dealership (Nissan charge $360CAD BTW) to avoid future "we only update sw" claims from dealership. Now we will see how it goes

Not unusual at all. EVs do not maintain an optimal state for lead acid which has led to issues covering nearly every manufacturer. Your 12 volt prefers to be fully charged as much as possible; something that NEVER happens in the LEAF automatically. There are steps you can take to boost (pun intended) your odds of a longer 12 volt battery life.

My original 2013 12V Leaf battery lasted 7+ years.
