Mine just did it. I have 5.7 eTorque. I’ve noticed it a couple of times on cold starts. I have 10K miles on mine.

Actual black smoke? Or just a spray of black stuff? If it's actual black smoke, it's usually a sign of running rich - I wouldn't worry on a brand new truck without any engine codes, since it's probably just startup enrichment.

For a black "spray" of stuff, it's likely just condensation mixing with soot in the exhaust

Honestly wouldn’t even be able to say I’ve just noticed it a few times from the driver seat so clouds in the back mirrors.. but so a new truck runs rich? Is this a good thing or a issue that will come up or should I just forget it

It is worth mentioning to the service writer when you go in for an oil change or whatever. You might have a leaky fuel injector. Then you get puddles of raw gas in a cold engine and on startup, you get black smoke. It can have bad effects on fuel economy. And worse, if one cylinder is running extra rich, the computer will attempt to adjust the fuel trim on that bank.... which could end up making the other cylinders run lean, creating their own set of problems. Get it documented now, in case it gets worse. Then there is a history in the Chrysler service history.

Then again, it may just need a little time to break in.

But it still should be mentioned. For all we know, there could be a TSB on it.

Mine was more of a bluish smoke and it happened this morning for the first time. I'm around 17kish miles. I will be monitoring to see if it happens again.
