3 1/2 years of 3.6 ownership

[Whaler27]

After reading threads like this on this board I intentionally decided to go with maybe not the most powerful but supposedly the most reliable 3.6L engine rather than some different version. Now at just 51 K miles I had a cylinder misfire CEL. Took it in for service thinking it's something simple to fix, just to receive the call that Jeep is replacing the entire engine (luckily under extended warranty). Guess I didn't get lucky with PentaStar reliability.

I’d say you DID get lucky.

The engine didn’t fail in a way that left you stranded, and you’re getting a brand new engine after three years of use.

The inconvenience sucks, but you’re starting with a new motor, and you’re odds of getting another defective one are remote.

What failed? Head gasket or lifter/rocker arm?

They were unable to diagnose exactly. just told me it's probably the head gasket.

You are probably right. Just have yet to see if they install the new engine properly and the vehicle drives smooth as it did before.

It'll be fine. A Pentastar swap in a Jeep is easy for a tech.

I hope it is so

Easy money. We do one a month at least.

I have a 2019 JLUR with 3.6/8A with the ESS (first thing I turn off after starting the Jeep) and other than some functional mods I’m still pretty much stock as it remains sitting on the factory 33” KO2s, wheels and suspension. I’m about to cross 24,000 miles in about 27 months of ownership and it’s my daily driver.

After all this time behind the wheel I’m of the opinion that the JLUR is an automotive masterpiece. It’s incredibly fun to drive, has an iconic aesthetic, is hands down the most versatile and capable vehicle south of $100K and when nicely optioned (LED, Cold Weather, Leather, 8.4, Tow, Proximity, Steel Bumpers and a textured hardtop came on mine) it is beyond comfortable and pleasing on the inside.

I’m keeping my 3.6/8A for the long term because of its proven track record of reliability, relative simplicity/availability of parts and that if taken care of should provide decades of service. They put the 3.6 in everything — from police cars and taxis to minivans and challengers — and I’m glad this amazing engine is under the hood of my rig. It’s really a blast to drive with this combo on the 4.10 gears with 33”s and for me is just the perfect setup.

BTW, I’m currently on oil change #16 in less than 24,000 miles. It’s just too easy and cheap (and gives me an excuse to hang out in the garage) so I’m going a bit overboard. What isn’t so cheap is my stubborn refusal to put anything other than top tier 91 in the tank. It gets about 16-17 MPG but it purrs like a kitten and has no knock whatsoever. I love this engine and the Jeep it pulls and don’t give a damn what it costs to run it. For me (and I suspect for many of you) it’s always worth it.

You’re changing your oil every 1,500 miles?

I have almost 50% more miles on my ‘20 and have changed my oils maybe 1/3 the numbers of time.

To each his own, but I feel you’re throwing money down the drain, man.
