Sounds like to me it's a blown head gasket and instead of pulling the head, making sure it's straight and sticking on another gasket, they went the route that makes the most sense, replace the engine. What I've seen (as I had this issue) was a QC problem of not tightening the bolts on the lower water pump flange. Thus the coolant comes out and sooner or later, it'll overheat. Luckily I caught mine in time. Since I cranked down on those bolts, they have never come loose again. So it tells me that Jeep need to look at that workstation and recalibrate the torque gun or look at whoever is working that station (which will never happen).

When you mass produce things, there will be failures. I had a cell phone that failed in a month. Got a replacement and it was fine. Looking in the intranets, a few other people had the same issue, thus it can seem like everyone is having that problem, thus junk and you need another brand.

Head gasket definitely was ruined after overheat issues. It should not have happened on a new vehicle...had to be worker screwing up during assembly of engine. Just wanted new owners to be aware of potential coolant leaks, etc. The service department and I never saw any indication of any coolant leakage before the engine failure.
You may not have seen any leaks, which can be tricky to find in a pressurized system, but your coolant was going somewhere.

Obviously, it was bypassing the head gasket. I suspect a defect in the gasket (rare) or potentially a flaw in the head mating surface.

No problems here evidenced by low coolant or milky oil.

Originally.....but I believe some of the 2.0ts are now built in the US.
Hmmm...I have an '18, it says Italy on the window sticker. Very possible that they've shifted production back/forth with all that is going on in the world these days.

Think post '20 MY most of the turbos have been made in the USA. Nothing against it, but I prefer mine Italiano 👌

My '22 is Italy. They're spinning up more US production, but there's still a lot being sourced from Italy.

Why? I'm just curious as to why an Italian would be better than a US version?

I'm just spitballing here:
When an engine is built in its home market (i.e., where it was designed), assembly line managers would have faster/easier access to the engineers who actually configured it, if or when design and/or production problems are identified and require resolution.

Yeah, it wasn't based in any specific evidence, more of a half joke. But I do remember that when I saw the made in Italy spec I was intrigued. I do like @Heimkehr 's reasoning though. Frankly the 2.0 seems like a win whether made in Italy, Mexico or the US, the OPs example notwithstanding.

Just bad luck for you. I just towed a 2,000 lb trailer 400 miles with no signs of any heat issues watching both coolant and transmission temps. I was watching because I was seeing a constant 5-18 psi boost. Averaged 16.1 mpg with speeds between 65-70 mph in windy Wisconsin. I was impressed.
You have an after market boost gauge? If not, I'm not aware of a factory option to observe boost as I have the 2.0 and looked through the Uconnect options for one.

Mine has over 94,000 on it and it still runs like a champ. That being said i did have to take it in once for a coolant leak. The dealership told me they hadn't tightened up the clamp all the way from the factory. Don't know if that is true or not.

I purchased a Bluetooth OBD2 code reader, and plugged it in after adding the related app to my phone. This allows me to observe boost, among other metrics, in real time.

That said, just getting into low boost numbers required more right foot than I had guessed (which was a neat learning experience, otherwise.) With that in mind, the prior claim of "a constant 5-18 psi boost" is a bit difficult to believe, based on my own experience.

The Tazer device for our Jeeps has a display option that allows the driver to observe the manifold pressure on the center TFT screen. Scroll to the bottom of the page here.

Appears there is a major engine cooling issue on new Jeeps and/or poor workmanship/quality control at factory.

Anyone else having engine, electrical issues with their Jeeps.

2022 JLUR four months old. No issues with my 2.0T cooling or workmanship. Hope your ride gets better for you.
