It was on a roll without having any issues

[BAULSAUL]

On my profile, you’ll be able to notice. There was a few issues in the beginning of ownership and shortly after. It spends some time in the shop for misfiring on cylinder one I think it was and it was extremely bad at the time. It was finally repaired because of a wiring harness that has shorted out or something. Then it started running rough again and it turned out. It was one of the O2 sensors. And now I have a code that popped up the other day while it was running a little rough at idle. It said that the downstream 02 sensor was running Rich. I reset the code to see if they’ll come back in sure enough , cylinder six is misfiring. It’s not out of control like it was the first time but it’s misfiring a few hundred times within a few minutes. But it goes away pretty quickly as well. Then you have the numbers on the sensors themselves. The voltage is on two I think is staying around .75 or greater and maybe there’s something else I’m missing. I’m so tired. It’s hard to explain everything again. What would your guys chase down first? Obviously I can’t stand the dealership. After all the issues I had the first time I was able to get the max care warranty through Mopar at no cost to me. But at the end of the day, the dealership is the last place I want to go

Recap, it was running rough at idle and I knew right away. It was a misfiring. The only code that showed up was a Rich downstream O2 sensor. That quickly went away and instead of that code, the misfiring code would show up for cylinder six. But that is also disappeared, but I know it’s still doing it just because I’ll check here and there and I can feel it. Let me know what anyone thinks. 2023 3.6 Gladiator Rubicon. All stock. No check engine lights on at all. Not even showing up when I read codes. It is misfiring an occasion, but not enough to trigger the code or light.

Then why get the warranty? The dealership is the first place I would go with that warranty. At least with it nonMopar warranty, there are other options.

To sum things up easily, the Jeep mechanics these days are not what they used to be. It’s not as simple as that. Today for the most part, we walk into dealerships assuming that they know everything and know how to fix everything but the truth is, they are mediocre at best. I unfortunately, I’ve had to deal with this multiple times. I would say about eight times to be exact. It was in the shop eight times for random nonsense reasons. I didn’t pay for the warranty. The dealership paid six or $7000 for the six year hundred thousand mile warranty that covers everything because they made nasty comments about my daughter while my dash camera was on.
I feel much more comfortable, changing O2 sensors, myself rather than a dealership. It took them eight days to diagnose one bad O2 sensor. This is just my personal experience in my opinion. I understand what you’re saying though. Was hoping for a general idea so I can start doing a couple things myself.

Don't lump them all together - some are actually very very good and know their stuff - and care.

Do you have a leaking valve cover? have you done a freeze frame to capture what all is going on at that time?
The O2 sensor could be a symptom, not a problem.

Sounds like a poor dealership, and not like the one I use.
