So I just completed my first week of driving my JLU 4xe HA and the wife and I have been loving it. This afternoon, I tried starting it and it was completely dead electrically. Thought maybe one of my key fobs was bad, so got the second key fob and still absolutely no electric in the vehicle. Then I thought that perhaps it was in some sort of remote "kill power" mode perhaps by mistake from the Jeep Wave service (hacked?), but then I noticed that there was no indication from the charge port of any power to the vehicle. I have not had the vehicle long enough to know all of the dash and charge port LED light sequences, but I seem to recall there always being some LED indicator when plugged in. Pushed in loose fuses in the underhood fuse panel as this has been indicated as a problem on new JLU's from the factory, but no change. I decided to run a multi-meter across my starter battery to see if I had any power and the battery under the hood reads 3.67 V!! Call to the dealership for them to address in the morning!
If a door is not properly closed could that drain the battery from the dome light? Most cars I know of have a 20 minute relay that prevents dome lights/accessories from killing the battery, but this is my first Wrangler so does anyone know if the Wrangler has a cut-off to prevent the starter battery drain from leaving dome lights on? Also, does the PHEV charge port keep the car battery charged or are these two completely different systems? I always keep the car plugged in once parked in the garage so that it is always fully charged and ready to go. I know modern cars with so many computer chips behave erratically once voltage drops below 11.X V so a bad starter battery might impact all systems as described but I just don't know. I have a battery charger but have decided not to mess with this complex system in the event there is a short somewhere; so I am leaving it up to warranty service to manage.
If you have any ideas let me know!
