This can’t be good Help !

[Frankiestoys]

Not trying to beat a dead horse but that basically convinces me that it was a small amount of water in the gas. It probably worked its way through and that will be the end of this issue. If that's the case I would just stay away from that particular gas station for a bit just to be sure.

It’s a better answer than I just got from the dealership
They want me to pick it up with no explanation
So here we go

I store mine during the times that we are not there and have cameras on it in the garage. Before parking it, I fill it up with non ethanol fuel when available. There is some alcohol remaining in the tank, obviously, from the corn gas we are forced to run, but I do add a bit of marine fuel storage to it also. The corn gas is hygroscopic so it doesn't help when storing an engine.

You might try adding something such as Star-Tron.

You will find that dealerships are very little to no help.

Intermittent issues are like that. It's a tough pill to swallow and it's a tough message for a shop to deliver, but if they cannot force the problem to replicate and cannot find anything in the computer to go off of - they can't do anything but keep the vehicle forever and drive it in circles, and they aren't going to do that for free.

I MIGHT have mentioned I'm a big fan of marine fuel additives in cases like this. Life in coastal NC meant water in gas a few times a year.

About gas -

My Dad worked for Gulf Oil. When he started he drove a fuel truck. After they all finished their deliveries, if they had any fuel left over they would drive around to any small independents and sell the fuel at a discount instead of hauling it back to the terminal. It was quite common across all brands. He said the common name between all the different drivers was "bastard gas", the mom and pops could have some Gulf, Texaco, Exxon, Mobil, etc. gas mixed in their tanks.

Gas is gas, right ? Wrong. Each company takes pride in their fuel, certain additives, cleansers, etc. at various concentrations. You going from Texaco to Exxon will not make a difference, there is not that much of a difference in your little fuel tank. Throw all the different gases into one large underground tank to sit and mix does make a difference.

Before each delivery, the driver was required to "dip the tanks". They carried this long wooden rod with gallon markings on it. Dip the tank, log the existing gallons, then deliver, dip again, make sure the stick matches the gallons dumped on the fuel truck meter. They had this pookie that they spread on the stick, if there was water in the tank, the pookie would change color. Delivery denied. On their branded stations. Bastard gas stations were not dipped.

I have always gone to a name-brand station, played it safe. One time while out in far west Texas in my 1985 VW Westfalia campermobile I needed gas. Beggars can't be choosers. I knew I was getting bastard gas from this little station. I asked the kid behind the counter where do they get their gas. Shoulder shrug. My van ran like crap for 200 miles. Dammit. I looked towards the heavens and said, "Sorry, Dad.".

Now with todays modern highly computerized engines, the negative effects of bastard gas is somewhat minimized. I still avoid it like the plague. Bastard gas may be a few cents cheaper, I don't care.

Rant over, time for coffee....my mind and my fingers are flying this morning...apologies.

I’m pretty sure it’s not the gas
Drove the truck for several hours prior and there was no malfunction I also used the same gas station to fill my Acura. She is running perfectly. If it had been a gas issue you would know almost immediately! I’m pretty sure it’s in the transmission

From my experience most Acura need premium fuel, a Gladi does not. So unless youre filling both with the same grade fuel it's coming from two different tanks at the station.

I'm going with water in gas. Could have been bad from the station, could be from condensation if the truck had sat for a while.

Thanks for your input again I do appreciate it .
In all honesty I hope it just was gas…
However I’ve been through this before with a Previous truck -2023 Nissan Frontier 4x4 what a total POS . I was a pretty devoted Nissan guy for years , having owned over Ten of their vehicles. I live in East Tennessee ( for now) and we have some pretty awful dealerships here.

Not a gas issue
Even the dealership said “ it’s just a fluke” there’s no such thing … I’ll keep you you all posted . I just hope this isn’t a precursor on my Jeep I’ve been through the mill with my last 4x4

The only phrase I dislike more than "it's just a fluke" is "they all do that". Something caused the issue and I'd appreciate the honest "I don't know" over a condescending/dismissive response.

"its just a fluke" and "they all do that" is the automotive equivalent of the Buscemi meme:

Very little frustrates an "expert" more than a customer who is better educated on the problem than he is

It's not perfect, but the Jeep app did help me a bit with an issue. I was at least able to narrow down any codes it may have thrown that didn't clear and know where to start. It shows up in the 'health report' on the app. Not a substitute for a proper code reader by any means but it at least let me know I wasn't crazy.

OP are you sure the issue your experiencing isn't the VVL going in to high lift mode causing a stutter sensation in the transmission? I talk about this extensively in several of my threads, it manifests as if the transmission is popping out of gear or stumbling, but it is actually within the engine. My brand new JL did it from the showroom and I swore up and down for weeks that I had bad gas or a bad transmission. Mind you, I was both a Mopar tech and a service manager in a past life and I am EXTREMELY sensitive to how my vehicles drive, and even with all my experience, I was thinking the worse thing possible.

On a stock 2024 and newer Wrangler or Gladiator I can get it to do it every single time at light throttle. Happens around 1800 RPM in 3rd gear just before 4th gear. It will also happen at highway speeds although less noticeable.

Long story short this stutter I speak of is the engine going into "high lift" which basically turns the engine into an atkinson cycle engine. It makes the intake valve lift a tad higher and paired with advancing the cam to get the intake stroke to last longer and at the same time it further advances the cam shaft to give the intake cycle more time. It is for efficiency reasons mostly. It will click in around 1800 RPM at light load and shut back off around 2800 RPM or sooner depending on load. Lots of myths surrounding the system as everyone for years claimed it's only used for "high power" but I've proven that wrong. Just wondering if this is perhaps the sensation your experiencing, because anything more severe IE transmission slipping, engine misfiring, etc. would throw a DTC easily.

To confirm if this is what your feeling, do the following:

-Warm up the Jeep all the way.
-Find a smooth paved roadway, maybe even slightly uphill if you can.
-Lightly accelerate to where the transmission is shifting around 2000 RPM.
-Watch your gauge cluster for 3rd gear.
-If you feel this sensation towards the end of 3rd just below 2000 RPM, this is what I am talking about.
-Jeep will always always always tell you that is normal and "as designed"

If this exactly matches your problem, the only fix is tuning. Multiple tickets turned in by master techs over the years ever since the PUG engine came to the JL in 2018, and Jeep refuses to fix it.

If this isn't your issue, I'm sorry for wasting your time lol

No no it’s brand new off the lot..

Sounds like 1 of 2 things
Defective Crank sensor , or a defective TCM .
