    I'm especially interested in this, given the speculation that it will be in the new Dakota, and that it appeared to have a few serious issues early in its life. It looks like they have been dealt with.
    A mechanic friend thought that the V-6 was dog-slow in a neighbor's Jeep. But he's into high-performance, and he'd think that my 3.9L V-6 with 180 hp in a Dakota is just as slow. Yet for me it's just fine.

    The Pentastar is my favorite engine being produced today. Have bought 4 vehicles with it, driven those over 300K miles combined with no issues at all. Reliable, good power, and decent fuel economy for the power. Will probably buy at least one more, unless battery breakthroughs come quicker than expected - in which case I may never buy another ICE.

    I know it's a matter of opinion, but the 3.6 in my Grand Cherokee moves it along very well. It feels and sounds more responsive than it did in my 2015 Charger or in my 2013 Challenger for that matter. Not sure if that's because it's the Pentastar upgrade engine or because of different tuning/gearing, but I'm pretty surprised.

    I still feel the 3.6 feels underwhelming in the Wrangler/Gladiator, but it feels strong in everything else I've driven with it.

    If your friend thought that it was dog-slow in a Jeep, he should drive my JK with the 3.8.

    I went from a 3.8 Jeep (4 speed auto) to a 3.6 (5 speed auto).
    Honestly the 3.8 really wasn't that much worse, and the 3.8 didn't have to wind as much to get to satisfactory torque.

    We've owned several of them in vans and 300s and never had an engine problem of any kind. They aren't hot rods, but compared to the 3.3 and 3.8 engines in similar models, they are hands down the best performers and get decent mileage.

    The Pentastar moves the wife's 300S just fine. Good gas mileage to boot for it's size.

    Love both of mine. Took the van and 5 people on our latest racing trip to the Slinger Nationals. Went 80 mph most of the way there and back two nights in a row due to a rainout and got 24 mpg! Very good engines IMO

    The 3.6 is not a great engine until you hook it up to an 8-speed! Then they are very satisfying.

    I'm in breakdown mode, stuck in Deming, New Mexico, there's a post for help, but, I did a super speed run with a 2020 Pacifica, and being a heavy minivan, relatively, I cruised at 85-95 both ways and still got 23.8mpg (average according to computer), and the couple times I had to "dash" for one reason or another, impressive.

    My son had lifter issues on his 2012 grand Cherokee. Seems to be something with that year both of my 2012 ram 1500 HEMI had lifter issues.

    Yeah, Ford had a lifter problem quite a while back, too, lifters are in the 3.0 Mazda (Ford stamps all over the thing), and one of them is extremely loud.

    I own a 6spd auto 3.6 and love it. Can't think of a better car for the money. My friend a GM master mechanic and Chevy guy agrees with me that the 3.6 pentastar is the best v6 on the market right now. But that's just our opinions. 140k on mine right now no issues except the oil filter housing leaked oil replaced it pretty easily. Other than that just maintenance. Mine is tuned I get 28 mpg combined in our Charger.

    I have a Trailhawk Cherokee. Love the 3.2. I have driven 3.6 Ram 1500s. Not bad if you are not doing constant hauling.

    I wish we would of seen a TT 3.6

    I agree that it is not an ideal truck engine.
    I dont think overhead cam engines are to great in trucks though.

    Many of the modern diesel truck engines use overhead camshaft(/s).

    2013 Caravan. Highway.
    23.7 mpg pulling an 8x5 U-Haul open trailer with sides, full of car parts, ac running. A few things stuck up 3 feet over the sides!
    31 + mpg Ac on, 75-80 mph, almost 90 degrees.
    No issues, getting near 100,000 miles.
