2018 jeep grand cherokee COMPLETE power failure
I have a 2018 Grand Cherokee that with no reason what so ever has zero
electrics.. Nothing works (obviously the battery is ok 12,3V tested) but i have
zero power everywhere , nothing works!!!! No lights no instruments no locks
Since its a 2018 model, it should still have factory warranty. If the truck will not start, have it towed to you Jeep dealer of choice for a warranty repair
unfortunatelly thats not an option right now..
Found it.. the auxiliary battery (placed next to the normal battery) is dead and not charging.. I replaced it and everything works now!
