Sorry to post on an old thread but I just wanted to share my experience. I bought my 2016 SXT California about 3 months ago. The car pretty much runs like new and has only 50k miles on it which is good considering how old it is. Today my key fab wouldn’t unlock the doors so I had to use the key, the gauges went nuts when trying to start and nothing else came on, my immediate thought was dead battery and confirmed the symptoms on this forum. However, not only do the gauges go nuts, but I hear a very strange loud clicking noise which sounds like it’s coming from the fan near the radiator, the headlights and tail lights are also flickering non stop really fast, I did replace the fab battery and accidentally pressed the panic button so maybe it’s trying to alarm but the battery is dead? The car gets no response from the fab so I’m not sure if the panic button actually worked. Maybe it’s the HID lights making the noise? There was no alarm sound but when I looked at the dash screen it looked like the lcd had lines and weird images on it that were random. I feel like the car itself has an electrical issue since a dead battery shouldn’t cause the lights to constantly flicker by themselves. The car started fine yesterday but I did notice low idle rpm so I though oh that is strange. Today not even a crank over and no power to anything. So what is this strange noise coming from the battery area? Is it the horn trying to go off from the panic button? It is the original Mopar battery so I know it needs to go, but is this dying battery issue actually causing electrical issues with the computers? I feel like this is not good electrical safety standards for a car, with the amount of computerized electronics in the car im afraid a dead battery will actually wipe it and fry something if I leave it connected, so I removed both term wires to at least not look like an idiot with my car parked on the road overnight, every light on the car was flickering dim and only noticed when it started getting dark outside. This is honestly the stupidest thing I’ve ever seen as far as a battery going dead, this shouldn’t happen because a low voltage. If anything nothing should work at all, not go nuts and flicker like im at a night club lol. I’ll try to replace the crap battery tomorrow and see if it didn’t mess up the electronics
