If you have an OBD dongle and the free CarScanner app, you can quickly determine if it is the battery module (to keep dealer honest).
Here are my readings before I experienced the failure and after:
Note there are values for Voltage variation and Percent variation. I don't know what the cutoff is but if the variation is over 1-2% (mine was 4.32%), I would be concerned.
My % variation was always below 1% until that fateful day last March.
