It's true that the JL's are a tech nightmare, but that doesn't mean they're impossible to work on.
It's also true that reliability is a big concern with this generation, but with a catch. I own a 23 JLU Sport S and can say I've put on 56,000 trouble free miles and couldn't be happier with it so far. Here's what I've learned about the JL's in my research when buying one.
- Stay away from the manual transmissions. Factory clutches suck. Stelantis never figured out the materials / tuning and have had multiple recalls for clutches exploding / catching fire. Almost 10 years later, they still suck. I also test drove a manual JL and have never hated a 6 speed more than that one.
- The V6 is okay. The usual slew of problems were carried over from the JK.
- The 2.0T IMO is a great engine. That being said, there have been a decent report of early engine failures, but not enough to write it off.
- The 8 speed ZF auto is fantastic. It's one of a very few transmissions that I can say does what it's supposed to when it's supposed to. In manual mode, when I ask for a gear, it gives it to me, no...."Oh, you want third? Hmmmmm, let me see, where did I put it,) This paired with the 2.0T makes for a very nice driving experience.
- The additional complexities with added computer modules does limit what the average Joe can do, but there has been a large amount of effort put in by the community to reverse engineer the CANBUS using commonly available components that is helping to open the system up for everyone.
- 4Xe's should have never been attempted. Period. Garbage, trash, other synonyms for poor quality.
- FSM's are available to purchase, and more people are uploading tech documents every day.
- Ignore the factory service schedule and change the 8 speed fluid every 60,000 as noted by ZF. Jeep states the fluid is "Lifetime" and never needs to be changed. Bullshit.
- Upgrading the mechanical systems is still pretty straight forward (Springs, shocks, brakes, arms, steering and so on)
It honestly comes down to research. The right combinations put together can make for a reliable setup from the factory. You just need to know what to avoid, and honestly, by this point most if not all of the gremlins are known.
The biggest thing I see is the large majority of JL owners what to turn these things into rolling TikTok / Instagram models while bolting on the cheapest / tackiest shit I've ever seen, and it honestly makes me sad as the JL's can look pretty decent when built right.
I've taken this on the same trails I take my TJ, and for a stock vehicle, I was impressed on on how well it handled / crawled. That being said, my TJ will always be my first choice, but I have no regrets about adding this to the family.
I agree with the majority that the Wrangler has become just another SUV, and that it's slowly loosing it's roots, but not quite yet.
These are my 2 nickles now that pennies are gone. My JLU for reference.
