I see that the "battery" light is on....j Would suggest a charging system issue? If voltage drops below 11 volts, it will shut off.....

I agree with @#4Jeep 1st Wrangler, likely a charging issue. Could be the aux battery. What engine do you have?

Yes it is a charging system issue.. when I test the battery it ranges from 12.4-13.5.. the dealer says it’s a malfunctioning alert since the battery voltage is good, the mechanic claims there’s no fix right now (just got it back Friday) then this message came up on the Jeep app

I’m not sure but I think it’s 3.0

Judging by the tach, you have a 2.0 4cyl. 3.0 is a diesel.

I have got the notification before.

What did you do to fix it?

Imagine how good the JL would be if it just ran a normal battery setup.

Reseating two fewer fuses would save the forums years off their lives for troubleshooting electrical gremlins

I did not try and fix it. It when away as I drove out of the area.

I got that message. After ignoring it, it went away, then came back with a vengeance.
My Jeep shut down and I was able to coast into a parking lot and be towed home.
Aux battery was shot. I removed it permanently, bypassed by taping the aux ground and rerouting the aux positive to the main, and installed a new main battery to be sure.

Wait, you don’t know whether you have a gas or a diesel engine…?

Either you are incredibly lucky and just happen to pick the right fuel each fill-up or you are kidding…
