    My 2019 Cherokee Trailhawk is Coming Up on 10,000 at 1 Year Old. The 3.2L V-6 has been Perfect so Far.
    The 9 - Speed Trans Has Done about 6 Strange Shifts So Far.
    Nothing Real Bad, but Slightly Irritating to a Retired Tool & Die Maker.
    I've Put about 800 Miles driving my Sister in Laws 3.6L V-6 Pacifica and
    a about 200 on My Daughters Pacifica.
    I Can Say that the 3.6L has More Low End Torque and More Power at High Rev's than
    My 3.2L V-6.

    I was Still Working at TEP When the 3.2L Came Out.
    I Remember talking with one of the Plants Engineers at the Time.
    He Said that They Went with the 3.2L Size Because it got About .2 TO .3 Better MPG.

    I’ve driven vehicles with the 3.6 almost continuously for five years, aside from a few months where I traded into vehicles without that engine. I’ve had it in a 2013 Challenger, 2015 Charger, and now a 2019 Grand Cherokee.

    It isn’t the most powerful engine in the world, but it isn’t underpowered either and I’ve never had any engine issues in my vehicles. It’s been a very solid engine.

    I have a 3.6 in a '16 300. It won't keep up with my son's Demon, but what will? Plenty of power for me, though, and smooth as silk. Gas mileage? Are you kidding?? On a recent 700+ mile trip I averaged over 37 MPG @ 70-75 MPH!! I'm a fan!

    I like engines that are mass produced and used across several platforms, and have a long history. Since we can no longer buy a new 318 V8, the 3.6 liter V6 is a great choice. My 2014 Avenger has the 3.6, and it gets the car moving and gives me peace of mind.

    I owned a 2012 T&C with the 3.6 drove it 100,000 miles and replaced it in 2019. The only money I ever spent under the hood was a flywheel.

    300C V6... 85,000 miles, eight speed. So far problems have been a sensor, $100, and a spark plug + coil at around 40,000. Get around 19-20 in suburbs and 32-35 mostly-highway; typical driving for us, 22-24. Plenty of power, only wish trans was programmed to downshift faster, it goes there but you have to plan on one second to downshift a couple of gears and then you fly. 0-60 time is within tenths-of-a-second of the original Charger Hemi.

    Bob early on the 3.3 Liter had issues. Back in 1991 they had a end play issue with the crankshaft. They fixed it by putting a larger flange on the crankshaft. I have a 1992 Grand Voyager with the 3.3 Liter with 357,000 miles and the engine runs great.

    Thanks, but that's a totally different motor.

    While the 3.6 is durable in this van, it doesn't seem to be sharing the same reputation in the Gladiator. A decent number are developing misfires early in life.

    Probably not the engine but the associated electronics.

    That was the hope. A new reflash hasn't eliminated the problem but some people with new parts on the 2-4-6 bank have reported success (shades on 2012!).

    Wow... the moment you said the first part of that I was thinking “2012!!”

    There's a story behind how that finally got fixed.

    Both my Charger and 300 had the 20” wheel/tires and suspension pkg. The sport mode really improves the trans shift points imo. On surface streets I always use this mode as it keeps it out of o.d or 8th gear.
    And then my next Charger had a Hemi. Forget about it! A lot more power with little sacrifice in mpg.

    Yup, the sport mode is great, we could have had that but only with the 300S and then we'd sacrifice the nice interior.
    That little sacrifice in mileage can be pretty steep on the highway. We get 34-35 on highway trips @ 75 or so.

    In my 2018 Challenger the 3.6 V6 much stronger than the same engine in my 2012 Challenger due to the 8 speed trans.

    Oh, heck, yes. You get at least 4 mpg more highway and 0-60 drops by two seconds. It's stunning.

    I have it in my wifes 14 Grand Caravan . Been reliable and now has about 105000 miles. Gets decent mileage though it is a little course and buzzy behind the 6 speed they use . I now have it in a 2020 Durango and what a different animal behind the ZF designed 8 speed . The thing hauls butt when it wants to , it is quiet and no buzziness , Gets 27-28 mpg on the highway and can tow 6200 lbs . It is just a totally different animal behind the 8 speed and I can highly reccomend it .

    The 3.6 V6 in my JL is night and day compared to the same engine on my JKs. The latest iteration is significantly quieter, runs more smoothly and is more refined overall.

    As others have said, mated to the 8-speed automatic makes the V6 feel a lot more powerful, too.
