I’m literally sitting at the dealer. They are replacing both batteries under warranty. Crazy how flawed these systems are. My Jeep only has 17k on it!

Update:

dealer just called, said they replaced the Aux battery. I made sure to ask them about corrosion, etc. They said the main battery is fine, but the Aux battery was def dying. So we will see how long this new battery lasts.
