Thanks for the info, I'm just anxious of being stuck on the beach or miles away from home, I have an oil change coming up, going to schedule a appt around then just wanted some info so the dealer doesn't just say can reproduce it sorry come back another time

Unless you have a CEL, the dealership is not going to drill down on any customer supplied Jscan data you provide.

Well................. it depends. (but I am NOT disagreeing with you!!)

I took my wife's 2021 Grand Cherokee to a local dealer - by the time I got half-way there it stopped misfiring. It was running perfectly.
I had caught it in the act when at home and done some dumps, freeze frames and printed it out and handed it to them. The one service writer looked confused. Then a tech was walking through and looked. That caught attention of others - soon there were 4 people looking over the logs I had given them.
Using that data they ended up finding a then new TSB referring to spark plugs.
No MIL and no stored codes. They scanned it and it came up clean. But they had my print-out.
On the other hand - they knew me.............. and I think they were curious?

Similar for my 2022 at the other dealership (where I bought it). I gave them the freeze frame data, details of how and when it happened, shots of it misfiring (JSCAN) and a history so complete they actually were able to duplicate the conditions - and found a STAR document.

But - Exceptions are rare, very. Most people will be turned away - bring it back when it's acting up.

I would agree to the point that it's not likely to help in most cases and it would be a futile effort.

They don't get paid to chase geese so unless there's an easy clue they can follow, it's not a good way to spend your time.

so unless they can replicate it, "its a jeep thing"
