It’s been thirteen years since production began of the award-winning Pentastar V6 engine at the Stellantis Saltillo South Engine Plant in Saltillo, Coahuila, Mexico. The Mexican engine plant currently builds Pentastar engines for 11 different Chrysler Group products. But in recent days, the 761,009 square-foot plant has celebrated a large milestone: the production of its 6,000,000th engine. The 6,000,000th engine was celebrated by the plant in a small ceremony. That engine is scheduled to find its way into a 2023 Jeep® Wrangler (JL) at the Stellantis Toledo Suppliers Park in Ohio.
Currently, the plant produces Pentastar V6s for several models including:

• Chrysler 300
• Chrysler Grand Caravan
• Chrysler Pacifica / Pacifica Hybrid PHEV
• Chrysler Voyager
• Dodge Challenger
• Dodge Charger
• Dodge Durango
• Jeep Grand Cherokee
• Jeep Grand Cherokee L
• Jeep Wrangler
• Jeep Wrangler Unlimited
• Jeep Gladiator
• Ram 1500

The Pentastar engine has been recognized seven times as one of the “10-Best Engines” by the prestigious specialized media WardsAuto. This achievement is a testament to the high-quality work done by the team at the Saltillo South Engine Plant, where the Pentastar engine is manufactured.

I wonder how many oil cooler assemblies they have produced. 😁

12 Million.

 

[Digger84]

And how many million head/valve issues

Rocker arms have to be in the billions

I had journey we put over 130K miles on and only had to replace the thermostat. A friend bought it from us and it now has over 160K still not a single issue. My 18 JKU has had no issues but it is low mileage. My father has a 19 Ram with a 3.6, about 60 K miles and zero problems. My wifes Durango has the 3.6 but it's under 50K miles. It's been nothing but good to me.

Sounds like some sort of propaganda....

Just to be clear that's 6 million from that plant alone. They hit the 10 million mark a few years ago, they're probably over 12 million by now. When you think of how many vehicles are powered by this engine the problem rate isn't that bad. The internet tends to blow things out of proportion.

Correct on Blow out of proportion... statistical data (consumer research well before the internet propagation) showed a unhappy/dissatisfied individual would tell a minimum of 11 individuals.. A happy would tell 3. From the looks of these posts that still appears valid.

Just keep pretending a flawed design is not flawed if it makes you feel better
Designs that are not flawed don’t require that the seller address the “internet hyped non issue” this one did so you just keep pretending it ain’t real

I put 90k on my 2012 JKUR and never had an issue. Wheeled nearly every weekend, a number of cross country road trips, and a number of high speed desert runs. Not a single glitch motor, tranny, electronics, hinges, or anything else mechanical. A few tech bulletins and that was it.

115K and 30K myself on my JK and JL 3.6 motors. Nothing but oil changes and smiles. My nephew had just turned over to 155K on my old JK when I saw him around the holidays and it’s been perfect for him too. The JL 3.6 / 8 speed is one of the best powertrains in the business IMO.

 

[Digger84]

So how many long term smokers claiming having no issues does it take to change that fact that overall smoking is a bad choice?
Same with a poor engine design how many examples of dodging the problem does it take to prove the known problem ain’t a problem

I'm sure the harshness of the jeep platforms suspension and how some are used contribute to some of these issues. Less complicated designs inherently mean less issues. However, this company and all its various acquisitions and mergers was never known in general for robustness.. The jeep wrangler really has no competition either to drive reliability higher. They sell no matter how many real or perceived defects thwart it. The extensive aftermarket is there to support most shortcomings also. The more popular the brand and model the more choices and less cost to upgrade.

Kinda like the GM Series 2 3800 V6. That engine had a strong run that ended I think in 2005.

12 million or not, the 3.6 is still a POS engine in a Wrangler. No bottom end torque, and in my experience, it really struggles to keep up with traffic any place above about 5000' elevation in mountains. It may well be a very well suited engine for a light car or anything with less wind resistance than a brick. In short, it is the modern version of the anemic Willys 134's, either variety, in a Jeep. Sort of reminds me of one of the Four Wheeler's reviews on JL/JT's-something to the effect it was struggling for breath. Guess they couldn't say GUTLESS.

The 3.6's greatest merit is that it was a definite improvement over the 3.8. That sets the bar pretty low-------- Would I ever buy another vehicle with that engine? HELL NO. Did we need the 392? Another HELL NO but it gave some bragging rights and some very inflated pricing to the brand. A 5.7 would have worked near perfect.

The 3.6 will never approach what was likely the most successful engine in history, the Gen I sbc and it's 100 million plus production. No plastic oil filter housings there.

It would have been nice in 2007 to have a six speed automatic and a light weight compact V8 in the new JK. GM drivetrain would have made the Jk's unmatched. GM had introduced the four-speed automatic and similar engine technology early to mid eighties. The 3.8 and 4 speed got a bad rap, it was a bit underpowered and gearing not ideal, but at least if you kept oil in it would last for 250K+ uneventful and not expensive miles. Again, it would show it's lack of power with a heavy vehicle and higher elevation and really struggle. Even a light jeep two door is 4k pounds, lot to ask out of 202 HP, but with proper gearing it gets by off road, It was simpler too which I find beneficial in the trails for reliability and quick repairs. For light trail usage and a daily family driver it would be great tp have the GM lt V8 engine and a eight or ten speed transmission. Not at a $35K+ conversion though that might not even pass for being legal. Best to enjoy them for what they are, warts and all..

The 3.6 is a compact motor. I wouldn't mind having the extra 20 horses the Ram 1500 gets in my 3.6 eTourque powering my JLUR.

100% agree........ A BIG CONGRATS ON 10K POSTS FRANK..
