Sorry to hear. What is causing the cel to come on? Whats the code? It took them over 5 try’s to fix mine. Most recently they replaced the wire harness for the engine. So far so good. The service rep told me at one point that when they can’t figure it out they have to get star involved or “jeep engineers” but they have outsourced this to India or some foreign country and they’re basically reading a troubleshooting manual.

How many trips have you made and spoken with the Ser Mgr? The GM if the Ser Mgr fails to provide findings and test results.. You should be more details than just post up a thread like this.

We picked it up on Saturday Aug 31.Went 10 miles and the engine light came on agin it was skipping and smelled hot. I have talked with Ass. manager and service technician. All I get is they are working on it.

Glad they got it fixed, thanks for posting the service details. Crazy that the new valve cover had a different PCV valve connection.

Glad you got it back so soon. Is this the 3.6 or the 3.0. Mine has been in the shop since June. That is pretty crazy that being a 2023 and already has a different PCV valve.

I hope this doesnt become a chronic problem. Its a 3.6.

Yeah I hope not. Sounds like they figured it out. The 3.6 nice mine in the 3.0.

This particular fix actually sounds like the fix for my truck

My 2022 has had 10+ P0300 instances since I got it. They all match the P0300/CDIFF service bulletin exactly. Drive it for 30-40 minutes (good and hot) on a warm day (80* or so) park it for 5 minutes, run inside and grab something, come back out and drive off with light throttle and you can guarantee it will throw a flashing CEL for several seconds, then it disappears. While the CEL is flashing, if you come to a stop the truck is running noticeable rough, then all it once it goes back to running perfectly smooth. I have logged a lot of data on it to give the techs at some point.

Lazy, haven't taken it to the dealer yet. I will eventually

What about Lemon law in your case? I dont know much about it myself but I'm sure someone on the forum must.

Nothing to lemon law since its never been to the dealer.

It's minor, doesn't affect my day to day drive, and I have a pile of data from my diagnostic scanner to go with it along with a copy of the TSB showing the correlation between my data and the TSB. Probably a simple in and out affair at the dealership - just haven't taken it yet.
