I have seen more than 1 battery pass its testing and not long after fails enough that needs to be replaced. Then the symptons go away!So sorry to hear about this. Sorry if I missed this elsewhere in the chain, but what exactly was your start-stop issue?
Asking because my ESS randomly stopped working about half a year ago. Every time I turn on the truck, I get an error saying the service isn't available because the battery is charging. If the truck sits untouched for 4-5 days, it won't start without a jump. Upon non-start, battery measures 12.1-12.3V, dash will say ~11.2V. Jeep said I have too many accessories (note: I've measured- there's no parasitic draw from those accessories), but that can't be right.
Not sure whether that lines up with your situation at all, but interested in whether you experienced something similar. (and, also, terrified to ask Jeep to fix it without setting my truck on fire too)
