Mine has 30 miles on it. It idles a bit rough when cold. I think its a lean condition....Maybe the fuel map is lean by design??

Similar here with my new Gladiator, a bit of roughness with initial cold start at high idle ~1500 rpm, then as idle rpm drops so does the roughness. Once it settles it's a decent no-concerns idle. Initially had me wondering in comparison to my wife's Infinity QX60 very smooth 3.5 idle, but perhaps not an overall fair comparison if considering design for comfort vs design for jeep's rugged & ready systems.Mine is occasionally a little "off" right after starting, but not a big deal. It settles down. I don't think it's anything to be concerned about. This engine is so much quieter than the JK, that I think I just notice the idle more.
I've had absolutely zero issues like that, but people who don't have problems don't usually post about lack of problems.Is mine the only JT with 3.6 that doesn't run rough and hasn't experienced actual misfires?
I can tell when the AC is on now and then at idle, especially when cold, but it's not "rough" and isn't "missing".
Misfires have been caused by so many things just because one person "solved" a misfire doesn't mean their "solution" will even come close to helping your specific engine problem. It isn't like "any misfire can be solved by one of these 2 things". Doesn't work that way. You should document the details, even use a reader and software and capture the events to show the dealer.Hate to bump this but I am having this issue. In cold starts idle is smooth till the temls gets around 145 and remained rough till it got to normal operating temps. No codes or check engine light on. If I give it Little gas and it smoothes out but when dropped to idle the rough idle will return. I've changed gas and upped the octane to see if there was a change. No change. Added red line fuel treatment and no change. My local dealers are less then stellar so Looking to get as much info as possible.
Just looking to see if anyone has had this issue and found a remedy. My jt ha 21k miles in it and has has 3 three oil changes by the dealer.
What did you get ?This was issued a few days ago, seems related. I didn't look further, as I sold my Gladiator on Saturday.

Nothing. Ever since we got a Tesla in April, I've put one tank of gas in the Gladiator. I rarely need a truck any more, and haven't been wheeling all that much either. So now worth having it, and people are overpaying for vehicles. And once you go Tesla you'll hate ICE.What did you get ?
I wonder if it was a campaign because no one was going in and letting the dealer do the flash, or the dealers weren't doing anything about it.This was issued a few days ago, seems related. I didn't look further, as I sold my Gladiator on Saturday.

the leaf is a great budget option - range just too short for most but I know a few folks leaf shopping right now. UTV would be fun!! you need a toyNothing.

Wife thinks we need two vehicles (we don't), so I am thinking either a super-cheap unpopular car like an old Leaf, or a sport UTV (we can license those for street here).
