I’ve been having problems with my battery dying over night and I’ve checked to see if I have left any lights in and the only light I see that’s still on is the light on the media hub. For some reason it will not turn offs. I already tried pulling fuses but that even that will turn it off. Any one might have a clue of what it is?

I am pretty sure it stays powered for about an hour after you shut the vehicle off. The only power are for the LEDs around the USB ports if you are not using anything. That is not enough to kill a battery even if the 1 hour timer no longer works (but I bet it does). I personally hate the feature in my wife's JGC because I have a wireless AA adapter plugged in and it stays connected for an hour when the jeep is shut off and it steals her phone calls if that happens. Not sure why Dodge did it this way because it makes no sense. Dodge says it is to charge your phone or other device for up to 1 hour after the vehicle is off. Who is going to leave a phone or tablet in the truck (alone) while it is charging unless the driver just sits there for the hour looking for the magical electron flow.

You look familiar too if that is you uniform. By any chance does Big Daddy ring a bell?

Thanks for the reply. Guess I have to find out what could be killing my battery. Yes that’s me in uniform, where were you stationed at?

It might be a bad battery. I would pull the positive terminal, charge the battery, and check the voltage the next day while still disconnected. If it is anything less than what you saw right after charging, it's not the drain, it's the battery. Now that said, a constant drain can "sulfate" (thus ruin) a good battery anyhow.
I would also check the actual 'parasitic' drain by testing the amp draw between the positive cable and the positive battery terminal. A normal load should be less than 100Ma with everything shut down. Way less, usually around 50Ma, if I recall.
But if you do test for this, use an actual car amp meter first, one that's capable of any possible load it might 'see'. If you don't read more than a couple amps, then you can proceed to troubleshoot with a regular (more accurate) multimeter. The reason I'm stating this caveat is because most multimemeters out there are only capable of loads under 200Ma. They're usually protected by a fuse, so even if the meter isn't smoked, you still gotta take the thing apart and replace the fuse.
Here is a link of common sources of excessive battery drain.. It's a dodge Ram, but the info given in this link is actually fairly generic.
