I have a 2020 Sahara unlimited. This weekend, she wouldn’t start. I read up on the batteries a bit to see if there were any issues and discovered threads about dual batteries and auxillary batteries. So, I removed the main battery, the fuse box assembly, and then the cover to the auxillary battery. To my surprise, the battery compartment was empty and no cables extending there as well. Did they discontinue the dual batteries or did my Jeep miss this on the assembly line and that is why my battery is now dead? Any help is appreciated. Taking to the dealer tomorrow after I jump start in the morning.
