Very interesting video.Why? The engines are among the highest rated out thereAlways love seeing a modern production line - I do feel overall that our Jeeps are pretty well built. Engines are a different matter.
Not sure who is rating, but would love to see that data. Our 3.6s have a high failure rate in the valve train; this is well known. I'm not sure of the long term reliability of the 4 popper, but I'm just personally not a fan of turbo 4 cylinders, and the 4xE is way too complex for me. I have both a 3.6 and a hemi swap and hands down have more confidence in the hemi.Why? The engines are among the highest rated out there
Well-known to those who hang out on the internet. But percentage-wise, no, not really worse than the failure rates of some others.Our 3.6s have a high failure rate in the valve train; this is well known.
I think the shortage of repair parts for the cam issue speaks volumes in regard to the " problem". I don’t know the whole shortage thing. Sounds fishy to me.Well-known to those who hang out on the internet. But percentage-wise, no, not really worse than the failure rates of some others.
Those rating it poorly are repair shops, youtubers and forum hanger-outers.
Those rating it well crunch the numbers and look at the over-all bigger picture.
Yeah, that 'well-known' thing is wearing thin if you do the numbers.

Summing up, we can say the Pentastar 3.6 reliability is way above average. It is time-tested well enough, and over 10 million Pentastar engines were produced to date. Despite that they had some issues early on, the 3.6L V6 Pentastar is great, durable, one of the most reliable engines available on the market right now.
I don't have the foil hat on yet - because there are many other parts on large backorders, and as members here who have hands in the supply chain, or dealerships, have said - not all of those numbers are for actual dead vehicles. Some are restock, distribution depots and other reasons.I think the shortage of repair parts for the cam issue speaks volumes in regard to the " problem". I don’t know the whole shortage thing.

With all respect here, comparing the 3.6 to other engines built today is similar to lowering the bar on quality. I recognize that in any comparison there has to be benchmarks or similar data to compare with but given the technology in use today, the engines produced should be much better quality than those produced earlier. Guess it all depends on how far back one goes for comparison but there are simply too many failures in todays Jeep engines in my view. Bearings, camshafts, roller cams and lifters have been around for a very long time and with constant improvement these should not be failing at the rates seen today. GM small block V-8's have been around since 1955 and have a pretty darn good track record over all. Same with Mopar engines but todays modern engines clearly have failures that should not be happening at the rate that we are seeing today. I don't know what the problem is but assume there are numerous factors involved. My personal opinion is that federal standards for emissions have pushed manufactures too far for the technology available today. There is a limit to how long an internal combustion engine can be expected to perform given the higher and higher output required of it. In my opinion, it is the single biggest reason these engines continue to fail far too soon. As an example, when you have to use thinner and thinner viscosity oils to squeeze minute amounts of additional gas milage out of an engine perhaps they have gone too far.Well-known to those who hang out on the internet.

A while back, we had a large parking lot with thousands of KIAs waiting for computers during the chip shortage. The difference there was the timing during the pandemic. What is the hold up now? With my tin cap on, I'm thinking they know they have a problem but they don't have a financially beneficial repair. The more they get out of warranty the better.I don't have the foil hat on yet - because there are many other parts on large backorders, and as members here who have hands in the supply chain, or dealerships, have said - not all of those numbers are for actual dead vehicles.

If FCA changed the contract for the source of the part - that alone can cause months delay as they shift the sourcing to a new supplier. Who makes the blanks, who machines the blanks to shape, who does the treatment they receive.
Lining up suppliers is still an issue for some parts (and likely the reason behind the delay of the JT 4xe again - it was last time, supplier/contract issues)
My sales guy here told me of the numbers of vehicles on a back lot waiting for parts - and not all of those are FCA 3.6-equipped vehicles. There are still supply issues.
Yeah, it's a problem, it's a huge number, but considering the millions of these out there - it makes sense in the bigger picture.
If you have over 10 million upgrade engines out there, and there's a supply issue, you are going to see problems by the thousands.
It's still rated as one of the most reliable engines out there - regardless of us and our armchair expertise with very very limited vision into the whole scene. There's much we don't know.
