Gremlin lists keep growing

[Spiffy]

I apologize for starting a new thread about my electronics issues.
I have charged my 12v battery for 12 hours by suggested from snakebitten. 13.2 voltage
Nothing is changed.
What's going on now.
1 Charging system error
2 Failed to do update
3 Interior lights don't come on when opening door
Trailer brake module "again"
4 Drivers window won't stay closed
5 roof rear camera image blank.
6 can't connect for remote start.
The charging system error just started. Before I put the smart charger on the voltage reads around 13 volts.
Some of these things might not be related like the camera. Before it just quit I was getting distortion like a lose connection.

The charging system error I don't know what that does.

Looks like a Gremlin hit your Thread title, "
Gremlin lists keek growing"

The only electrical gremlin I had was the trailer brake module error. The dealer performed TSB 24-2116 5 months ago on mine and it’s still all good.

Is it possible there is an issue with your alternator? If its still under warranty, I would bring it in and have it looked at.

Stupid question, did you charge the small battery under the back seat? That fixed all of my issues.

No. I didn't think about that battery. What does it do? I thought all these discussions were about the engine 12v battery.

If it’s a Powerboost, replace both batteries and reset the BMS.

**Charge the batteries fully before installing.

Please help me to understand. If my main 12v battery shows 12.5 idle and 15.2 with keey on what's the problem?
I just don't want to spend a ton of money only to find it wasn't the battery's

Another thing just started.. the moment I turn off the truck the screen says it going into sleep mode. I check the 12 v battery and it's showing 12.5v. Even when I hook up a smart charger it shows 13v and wount charge any more.

Also. In the most recent replies the small under back seat battery is coming into the conversation.

It seems to do most of the interior electronics etc, at least in my experience. Definitely throw a charger on this.
