HELP! (Solved Kinda…)

[DailyMoparGuy]

I THINK I have a new issue to this forum. In short, my truck will not turn OFF, yes, off.

Edit: Nvm, found an existing thread on it.
https://www.jeepgladiatorforum.com/forum/threads/truck-won’t-shut-off.71743/

First event:

I just had the batteries replaced today at the dealer. Drove home, backed into my spot, put it in park, then pressed the ignition button. It doesn’t go off…no worries, I didn’t press it hard enough. Pressed it again, nothing. 10 seconds go by and then it worked. At this point, I’m thinking maybe it had something to do with me having both key fabs in the truck at once(I don’t know, just being hopeful). I go on with my day.

Second event (current situation):

Not even an hour later, I hopped in my truck, started up and drove 40 seconds to my grocery store. Successfully turned ignition off upon arrival. AWESOME. Hop back in after shopping, start her up and drive back home….here we go again, it does not turn off. Now I’m typing this.

Any ideas fellas, I’m all ears

Edit: It just randomly turned off as I finished typing this. There was also a weird clicking noise as it shut off. I’ll deal with it tomorrow. I’m still wanting to hear opinions though obviously.

Also there are no messages on the dash. No indication of a problem whatsoever.

Damn, I thought I was special

I was thinking the ignition switch too but it felt like a big coincidence with the batteries just being replaced. But based on that article, that could’ve been the cause of all this battery stuff anyway. I just assumed the batteries went with age (3 years old).

Thanks for sharing by the way. For a moment, I forgot that there were other websites outside of this forum lol.

Boy, that's definitely very generic. That applies to almost any modern vehicle.
It's one of those where they toss in the headers based on your search words.

Lol they kind of all apply to what I just experienced in some way it seems too. But it’s a nice start. I’m not an electrical guy AT ALL so it’s not an issue I’ll be solving. Just wanted to check if anyone else had the issue mostly.

The more I read, the more it feels like a wild goose chase to me lol. Luckily I don’t commute to work. I’m more intrigued than anything right now.

Batteries can go for a variety of reasons - age is just one of them, and how they've lived their life will vary that age at which they start to fail.
Can fail at 2 weeks to multiple years. A couple of owners of "other Jeeps" had batteries go bad in a matter of weeks.

That generic site is ok, but it's pretty generic. There's a whole lot of site out there like that which tailor the headers and names of the vehicles based on what your search terms are. Any of that would apply to Ford, Chevy, whatever.
I laughed about the ignition switch part because they say a bad switch will cause dash lights to flicker. No, not with a Gladiator. Maybe with an old-style ignition switch that is a switch through which the power for the lights flows. So - it's extremely generic.
First clue was the "URL" with this embedded -
-turn-off/#:~:text=If%20your%20Jeep%20Gladiator%20fails%20to%20turn%20o

I'd bet if you typed in "Chevy Colorado" instead - you'd get the same results.

They are "smart sites" and will read like a form letter with the names changed but the rest is the same no matter who it's sent to.

Best bet - dealer............. unless you feel like checking every fuse, every relay, every connector, etc.

Try putting a battery charger on it overnight and see if it helps any. The dealer probably did not fully charge the batteries before installing them.

Smart sites, interesting. Yup I’m planning to give the dealer a call tomorrow.

If I recall correctly, it's in the "book" that they are to charge batteries before installing.
But - they probably don't read those books.

And we circle back to - always charge new batteries before installation.

I didn’t even think of that. The voltage reading was 14.2 when I drive off from the dealer (DRLs, AC, radio all on). I figured it was fine.

Too low maybe?

That is in the expected range, it shows that it is trying to charge the batteries. When the batteries are fully charged, the running system voltage will drop to around 12.9.

Problem is - that's right from starting and driving off - so unless it stayed up there for a length of time, it might not mean much.

That's the charging system voltage and unless you watch the whole history, and track it closely, that single number won't mean much -other than if it's not cold out and the batteries were fully charged and the IBS reset, that would be a bit high.
Fully charged batteries in summer type temperatures should be running less.
But even fully charged batteries can see the charging system voltage that high for a while after a cold start. It's got to work to get them topped off again.

The real thing to look at is the voltage of the batteries with the truck not running.

Low batteries maybe, with most everything on CAN BUS any voltage decay or ground issue will make anything on that backbone freak out, problem is it would have similar backbone issue @ start request also, in theory anyway. I’ve seen batteries cause all sorts of havoc with multiplexed networks. Do a once over on battery connections, loose grounds play hell with modules as well. Beyond that signal A isn’t getting to cavity B, or module can’t rationalize the request(also battery thing). Maybe something as simple a complete latched relay, won’t unlatch. Find the relay and exchange it with another. Say PCM for wipers. I haven’t been under the skirt on these to know what the hell is there in PDC for control relays so might be way off.

I was just having a bit of fun with the thinly veiled reference to the Wizard of Oz. Thanks for playing along.
