I have a very frustrating issue with my JL. I got the jeep in 2019 with only 49 miles on it in March. The next winter 2020, when the temps went down to almost zero the battery died in a coffee kiosk line. The dealership put a new battery in it. Two weeks later it died again. So they put a new battery harness on it. 2021 winter battery died.Furthermore, all of our Jeeps (we have 4) also show 14 volts +/- during regular operation. *I just checked our Jeep Grand Cherokee @2 hours, @4hours and 6 hours into a 8 hour drive and the display consistently showed 14.1 volts, with a healthy battery and no major power draw.On startup 14.5 to 14.8 is probably normal. But after driving, voltage should go down to about 13.8 to 14.2. In really hot weather it might run as low as 13.6. Lights and heavy draw on the electrical system might take those numbers down another .2 volts or so.It’s very possible, there are several things that keep ESS from engaging and battery charging is one of them as I believe the JL is programmed to monitor that voltage of the ESS battery and if it’s low it won’t allow ESS engage, it’s actually a very over engineered system, it’s best to have both batteries load testedTook the wrangler in for an inspection and to talk to someone about it. On the drive in, voltage showed a steady 14.2V and the Stop/Start message was gone. The inspection came back with no problems, though of course the Stop/Start system was outside of the standard multi-point inspection. (Also, replaced the Stop/Start battery two years ago ...I’m viewing the voltage reading for my ‘15 JKU thru may Alpine ilx 207/ OBD II port. Reading shows approx 13.9 at idle and up to approx 14.4 while driving. It does ….
