Battery or other question

[Jchamp]

Mine is a 2021

I'm not sure but we may have one. I'll have to look. I know the start /stop hasn't not worked thankfully. But I do drive short trips so I'm not sure if that makes it worse or not. It's still charging on the tender. None of it started until it sat a couple weeks. Almost as if it caused it.

Sometimes even installing a new battery requires "topping off" the charge with a trickle charger. When I replaced my battery with an OEM from a dealership (son's business account) I hooked it up to the tender overnight before everything worked as intended. Now I have to turn off the auto stop-start, but I figured I was on borrowed time anyways.

I'd venture that your battery is on it's way out. The truck does a sort of self preservation thing by shutting off things that aren't really needed to operate it. Usually the first thing to go is the ass. Gotta drive it more to boost the battery voltage. How old is the battery? Over 3 years dump it.
