Battery forever charging.

[DocTwinkie]

3.6M JLUR with hd towing and accessory button package.
So start stop hasn’t worked in like 6 months. The auxiliary buttons also tend to die if I’m parked a day or two but come back after about 5mins of driving.

The dealership replaced the battery and battery sensor. Nothing. Goes back in again tomorrow.

Thoughts? It worked for about 7months no issues. The only thing installed is rock slide engineering step slides on Aux 1 with power to that line at all times. I’ve tried turning aux 1 off. No change. And those step slides have been on there since day 1 and it worked fine for half a year.

Which battery did they replace? There’s a ton of threads on this topic. It’s gonna be that your AUX battery is failing. Just bypass it and disable ESS.

I had the same issue, took it to the dealership, they tried charging the main battery and it failed, same with the aux battery. They replaced both under warranty. The car was there for 4 hrs. Got it back, everything works fine (been 3months now)
