Jeep was built 9/24/21. Went in today and they said it needed everything again! They didn't even tear it down. They said we will order parts and I said don't bother for this dealership. Called FCA and opened a ticket. This dealership did say they have about 5 vehicles with this problem. FCA recommended another dealership. I take it to another Wednesday. Of course FCA plays dumb as well as t he second dealership.

I understand how odds work, the numbers, scale and so on - more vehicles, more bays in the shop, more likely to see the more common issues. The more lottery tickets you buy, the greater your odds.
But I've now asked service advisors at two dealerships about cam issues with the 3.6. I just left it generic and only mentioned 2020 and later, and said I've been seeing a couple of people talk of this (lying) and wondered what they had seen.
They acted surprised and said they'd never seen any issues with cam.
So - either they are mistaken, have forgotten, or don't know what's really being worked on in the back rooms, or something......or, maybe they simply haven't run across it yet.

I have lots of racket when the engine kicks down from cold start, and then a steady tick before it runs at peak temp for a while. I can hear it best from the driver side, both inside and outside the vehicle. Sometimes it’s louder than the video sound. Any thought would be appreciated. After the axle leak repair, I just dread more BS to deal with.

I’m at 2,000 miles or so at the moment. Mine sounds diesel-ish at idle (I’ve owned two diesel vehicles). Definitely got some personality to the idle, lol. I really only notice it when it’s warm. I noticed that by maybe 1,000 miles.

This was one thing that I noted on the survey that I just completed. It doesn’t take away from my enjoyment of the vehicle, but the way I put it…I’d mention it to someone that’s in the market, as most folks looking to spend that kind of money would likely not be amused by it.

Someone buying an off-road truck, a Jeep, no less, isn't going to be bothered by sounds, otherwise the cabin noises would be even less amusing. It's the market -the type that buys this sort of vehicle will deal with noises better than someone who is buying a Lexus sedan.

I'm bothered by sounds.....Especially ones I know shouldn't exist. Like that steering clunk they still say is 'normal'. Or the transmission clunk when first rolling out for the day (some thread here said it is a normal 'unlock' function of one of the clutch packs). Just saying.... When a guy spends 60 something K on a rig, its kinda a big deal. Noise to just be noise is one thing. but man I come over this thing all the time to make sure its ok and not gonna break down somewhere.

Do yo know if anyone with the 2022 MY's have experienced the cam failures or is it just a 20/21 MY issue?

Last part first -
I've been wondering that myself. I have not observed anyone with a late 2021 or 2022 model with cam issues, but then I've not seen every communication on the internet, either.

I agree on the abnormal noises. Steering clunks are not normal. Sounds like that indicate problems. You'd not ignore abnormal sounds. The 4.0 in my car sounds like a truck engine, valve train noise, a certain amount of injector noise - but it's all normal for that year engine. MOPAR took great pains to quiet the 4.0 down because more and more women and families were buying Grand Cherokees and complained about engine sounds.............. normal engine sounds.

Auto transmission clutch pack unlock? Huh? If that's the case, they would all do it - and unlock? They are either applied or not applied.. It's by hydraulic pressure, not a mechanical lock that will clunk. There literally should be no clunk in an automatic. The planetary gear sets are meshed at all times and there's no play there. I've yet to hear any clunk or for that matter any sound in the 8 speed Jeeps we've owned. In fact, they are really very quiet transmissions, IMO.
Why would it only do that the first time? Those clutch packs operate the same at all times, they are either applied via hydraulic pressure, or not, and there's no difference between a fresh start or coming out of the store after 15 minutes and taking off.
Now - if you start cold, put it in gear and hit 7 mph, the ABS will calibrate and there will be a brake clunk at 7mph, but it won't happen again until you shut down and restart later.
Yes, there is a brake noise at 7mph, but with mine it's so subtle you have to REALLY REALLY listen.

interesting. So the ABS calibrates each time on cold start at 7mph? That must be it then. Ill pay attention to the speed. Its only cold start. Didnt mean to derail the thread - bad habit….

i love the way my 4.0 sounds. Specially matched with the 6spd. It just sounds all sorts of right. To me Anyway…

maybe tomorrow I can get a sound clip of my engine ‘tick’. Its not consistent. Also not loud. Sometimes it happens. Sometimes not. but Im still learning with these newer engines. Last time I tore an engine apart for rebuild was 15 years ago. Yuck feelin old hahah. But it might be helpful for the op and the community as its a different type of sound than what I have seen others post here.

Cabin noise is a given for this vehicle, given the design. I’m amused whenever I see a post with someone complaining about cabin noise, it’s too hot with the doors off in the summer (actually saw that in a review), etc.

Where I’m going with my previous post is that if someone is on the fence between a Gladiator and a TuRD Tacoma or something similar, the engine noise is something that they’d want to know.

Someone that knows what to expect from a Jeep product is not going to be shocked. I.e. CEL and having to shut it off before 1,000 miles. My reaction was “took it long enough.”

My expectations were so low that Jeep would have to work pretty hard to disappoint me.

And my luck with Jeep has been the opposite. Mine is so quiet, both my wife and I have stopped the truck and started to get out before realizing we didn't shut it off. Very quiet engine.
She actually has gotten out of her Grand Cherokees forgetting to shut them down.
No MIL lights, no misfires. It starts, it runs, it's quiet (except for cabin noise and back in 2019 the dealer saw I was driving a Silverado and warned me the Jeep would be LOUD, and any wind would be very annoying. He wanted me to know........... hey, I've driven early Broncos and Scouts from decades ago, Blazers, etc. - might as well be running your tractor. Rattles, wind and more. This truck is relatively quiet compared to those, cabin is not quiet compared to a thick walled, insulated Chevy.
I expected it, dealer made really sure I knew all about it (he was concerned)

Multiple reasons the doors and main top stay on a lot here - heat, wind, 100% relative humidity, dew points 91 or better.......... high UV warnings. The hot wind in the summer will take your breath away, when you are hit with a side gust of 30-40 mph, it's like someone stuck a Hoover hose on your face. The other thing is our "forecast for today is for clear skies, gentle breezes and no chance for rain" and 2 hours later, a gully washer, 5"/hour. Or worse, a record-breaking derecho and the forecast was for mostly sunny, no rain.
So - you take off doors and roof at high risk. Wear plenty of sun block, take a hat, tie the hat on your head, and remove anything that can move from the cabin - the wind will remove it for you otherwise.

Anyway - no engine tick other than the expected injector and valve train sounds that are normal.

This is what I consider normal engine sounds. Ignore the crap K&N filter I have since thrown away - this was right after getting the engine in, before I got the air box rigged up and made other tweaks -

Mine used to sound like a Diesel at idle too, was told its normal. 19k miles on the clock and 200 miles from home this happened....

That's a very different sound from a tick.
That's the result of a knock. That baby tossed some parts - hard.
I can handle slight ticks, but if I ever heard a knock, I'd be knocking on the dealer's door and insist they keep it until diagnosed and repaired. The goofy thing is that there are tricks to diagnosing lower end knocks and sounds. I guess they go to school to read their smart plug-in tools, and not to learn how engines work inside, and troubleshooting sounds that don't belong.
Depending on load, acceleration vs. deceleration, and other factors, you can figure if it's rod or main bearing with a few simple tests.

Mains also have a deeper sound than rods and the sound will change with load. Rod knock sounds typically are there as quick as the engine starts and don't get better as it warms, may sound worse due to the thinning oil. By the time there's play in the bearing, it's like a hammer on the oil film.

Mine sounds exactly the same. Upon start up until it reaches temp and subsides a bit or goes away completely. I have had it not present itself once or twice as well. I may have the dealer inspect during my final free Jeep Wave svc. Keep me posted and I will do the same!

Fortunately the dealer is replacing the engine, but I am assuming that the ticking in the head ( diesel sound) led to the premature wearing of something rather important which then found its way into the cylinder.... In turn causing the rod to try to escape through the engine block. Was also told that a manifold needs to be replaced with the motor. They didn't specify intake or exhaust, but if exhaust I am assuming that some of the chunky bits made it out there as well.
