I'd wager that this will fix it. Fiat wiring isn't really stellar, especially the connectors.

Finally after a week heard back from the dealer according to them it’s the entire wiring harness so they are replacing it. So it has a new pcm to brand new o2 sensors and now a new wiring harness hopefully it works if not I’ll let y’all know.

hello @jacksonator56 so a little differnt scenario, mine is a 2020 with almost 60,000 km on it, Im having the exact same issues, and is now in the shop for the 3rd time. what ended up being the fix for your unit?

According to the dealer it’s the entire wiring harness but it’s been two weeks and I still haven’t heard anything just crickets. I suggest any issues you guys have, reach out to @JeepCares I have been in contact with them since all of my issues started so they are aware of everything as well as how shitty the dealer is being about everything by the way of your in central florida never take your vehicle to napelton they are complete shit all the way around.

Im in Northern Alberta, My dealership has been excellent in getting my truck in each time, and since wednesday morning has had a mechanic on it non stop. so I cant complain about that. however if this is an ongoing issue for close to two years now, Im curious why there isnt a fix, and why are they continuing to sell the same engine design if there is a flaw. I had a 2015 JK that ran flawless for the most part. @JeepCares

So I heard from my dealer I bought it from yesterday and they told me that my issue was caused by a pin hole leak from a coolant hose leaking on the ignition coil and shorting it out making it misfire.. parts are supposed to be in Monday and fixing it then? To be continued...

So finally picked up the jeep today talked with the techs and looked at the print out so they replaced my wiring harness and all my 02 sensors also replaced passenger valve cover gaskets they were leaking oil and that caused the 02 sensor to short multiple times. But the big issue was the wiring harness pins have only driven it for about 30 minutes but no issues yet time will tell the last 3 times took a few days to show any signs

Got word from My dealer today, fairly extensive find, so apparantly the fuel rail was plugged up, 4 of the 6 fuel injectors were leaking dumping raw fuel into the intake, and the when the intake was removed raw fuel was running out of it, this would definetley explain my lack of power, new fuel rail and injectors are on order, due to this bullshit pandemic everything is on delay, there saying parts should be here end of the week, but we will see, hopefully this is the fix.

I currently am sitting at 14,000 miles and hasn’t been back other than oil changes so fingers still crossed it holds

Perfect. The dealership I’m dealing with couldn’t figure it out so I told them about your situation and it turns out my valve covers are leaking oil. So now I’m just waiting for the rest of the pieces to fall into place. It’s been there a week today.

Had this exact same issue at just over a 1k and then around 3500 with the issue being a valve cover leak causing the o2 to go bad. So far at 6000 miles no issues yet, but the unconnect app says I have check engine light on now but nothing displays

Wow. It’s becoming more common.

Wow. It’s becoming more common.

Just ran into this very same issue Today on my ‘22 sport S. 1477 miles with blinking check engine and rough drive. Got it towed and will have a chat with the dealer tomorrow about this thread if they haven’t made any of their own conclusions. I’ve owned 4 wranglers and never a single issue. Sheesh.
