Engine issues 3.6L

[JAVYPRO]

2020 Rubicon with 65,000 miles. Noticed excessive ticking noise when at 4kRPMs. Took it to the dealership and it likely will need rockers, lifters and camshafts on passenger side at the swing of $5,100
A $68,000 vehicle that cannot make it to 60,000 miles without crapping out is a piece of garbage.
I am so pissed off it has been treated like a baby, I love everything about it and this bullshit happens …..
Jeep knows about this crap and DO ABSOLUTELY NOTHING to fix it.
I am getting rid of it and f*** it with Jeep.

Not even my 1990 Mitsubishi Montero at 375,000 miles has these issues.

I feel your pain. My Rubicon had the “ticking” noise at 63,xxx miles. I took it to two different dealerships who told me it was a lower motor knock and that I would have to replace the motor at the price tag of over $12,000. FCA was a joke to deal with and dragged their feet helping me. I thought it was a top end passenger side tick. Me and a buddy took the passenger top end off the motor and found the notorious problem. Worn camshaft and rockers. I Replaced them camshaft and all rockers and lashers for $1,000. FCA said they wouldn’t reimburse me because I’m not a “certified mechanic “. Two certified mechanics diagnosed it wrong. FCA was horrendous to deal with.

It does seem to be a very common issue, but that's the Internet.
$68,000 for a 2020?

I have rebuild two engines but I do not want to mess with this. Imagine what will go wrong at 100k miles.
I also have a 1964 Jeep Willys pickup truck and I always wanted the JT and love evrything about it but, what a disapointment. FCA failed misserably on the delivery of a trully good and reliable engine. So sad, others should not buy.

This is a 2020. Those had more of this issue. The later model years, not so much.
I've had several Jeeps with the 3.6 upgrade and never a tick or mechanical failure at all in any of them. I had a 2020 JT and now a 2022 JT - no ticking, no valve train issues.
Whatever was going on in the 2020 model year seems to have been mostly dealt with in later years.

One Jeep with a problem, and done with Jeep.
Comparing a 2020 Jeep to a 1990 car - old school tech?

That is about what a fully loaded 2020 Launch Edition was going for back then. Also, nobody was discounting early on unless you had a below invoice dealer.

Wow that's pricey!! Take it to an independent we get them done with cam's, lifters, rockers everything for $3000 for the whole motor. I'm a dealer and fetch a good rate but $5500 for 1 side is stupid high!! If your going to do it do both sides at the same time

Ive had the lifters replaced on the left side and at that time it was under 60K so it was covered and now its ticking again so taking it in on Tues for what I suspect will be the lifters on the right side. Im now at 67K miles, purchased 2021 Mojave with 50K miles last Oct and got the extended warranty which has just about paid for it's self. Ive also had to replace the driver side door handle and had all four doors that made a clicking sound when opening fixed. Ive never had this kind of engine issue or number of repairs with any of my previous cars, 2001 Nissan Maxima replaced by 2013 Nissan Maxima, 2005 GMC Envoy replaced by 2020 GMC Acadia. A little disappointing but still love my Jeep!!!

And that’s just the engine… oh, a bigger better faster transmission is needed…probably a driveshaft or two too…and and and …..(to infinity and beyoooooooond….)

I mean, a 3 year, 36,000 mile engine warranty tells you what kind of faith, and risk they're willing to take in and on their product.

That is the bumper to bumper. Powertrain is 5/60K

And of all of the Jeeps with the 3.6 PUG engine we've had, the powertrain warranty has been used 2 times -
2021 Grand Cherokee - misfire - spark plugs, a TSB covered it, all under warranty, no fuss, no hassle, dealer shop took care of it perfectly.
2022 Gladiator - hot restart misfire. PCM flash (actually, a CCDIFF relearn fixed it) - they eventually came out with a TSB, mine was covered very nicely and graciously by the dealer.
No other engine issues with a 3.6 PUG engine.

2023 JLU 4xe (doesn't count on the above - it's not a 3.6!) - transmission leak. Transmission replaced under warranty. A ZF issue, NOT a Jeep issue because ZF makes those transmissions in Germany (or was it Austria - I think Scotty K said they were made Austria)

It's 60k and 5 years on the powertrain.

OP, I'd give @JeepCares a shot with this. You aren't that far out of warranty. Jeep coverd a Uconnect 8.3 for me well after the 36k warranty due to a known issue. You never know. THey don't have to cover it, but they just might.
