Have you helped one single customer actually get their Jeep fixed?
I’ve had this problem since new off the transport truck 4 years ago on this very day. Been to the dealership about 20-30 times for this exact issue & there is always some ridiculous excuse for not being able to fix it. They can’t even figure out why it happens (so they say).
JEEP knows about the problem and I want to know why they won’t fix it. My guess is because it’s too expensive to fix & that would be the ethical thing to do… which is why they won’t.

They messaged me when I was having Telematic problems and had me send the VIN, then all I heard was crickets! They have yet to this day responded back. I finally showed the dealership the issue next to one of the new ones on the lot and they opened a Star case and finally figured it out. I wouldn't count on ever hearing anything from @JeepCares! That screen name is an oxymoron...

@ Scrubb84
LOL, I feel the same way...its so frustrating that I laugh to keep from crying I guess...
I've been having the same issue (engine noise/rattle that sounds like keys in lower gears, i.e., 2nd and 3rd, anywhere in the 1,500-3,000rpm range) and have been to the dealership a handful of times for this issue but have never gotten any type of resolution or acknowledgement of the issue/noise, except on one occasion which they acknowledged hearing the noise and reported it was due to the oil level being low and needed to be topped off. On that occasion they said they topped off the oil then test drove the truck for an extended period and the noise had disappeared...as I'm pulling out of the parking lot I hear the noise through 2nd and 3rd gear...immediately sent a message to my service advisor and he said a service manager would reach out to me...followed up with him on several occasions letting him know I hadn't received a call back which ended up never happening (all of this occurred while under bumper to bumper warranty)...fast forward to today (out of bumper to bumper warranty but still covered under powertrain warranty) where my truck has been sitting at the dealership since 9am (because I called to schedule another appt., not because a service manager called me to discuss) and they still haven't looked at it so I am picking it up here shortly, obviously with no type of resolution, and will try another dealership I suppose...FRUSTRATING to say the least.
FWIW, I had a service manager ride along with me on my 2nd trip to the dealer for this issue so they could document the noise I was reporting (which I explained sounded like "detonation") and when he heard the noise 10+ times during our short drive, he agreed that it sounded like engine "detonation" and that he would have the service advisor write in the notes for the tech to speak with him if they were having issues replicating the sound but when I picked up the truck after they had it all day, my service advisor had left early for the day to go on vacation, and the service manager was gone for the day as well (I guess everyone dips out early on Fridays, lol, guess I can't blame them) so whoever checked me out had no clue about the outcome of the visit so they called a service manager who was still there but he also had no clue on the details of my visit and just read the report back to me which was basically BS...it simply stated "Noise couldn't be replicated, no issues found" and that everything else was in working order. The following Monday I spoke with the service manager who rode along with me who advised me to bring it back in so they could look at it again and he would make sure to go back and speak with the tech when it was being diagnosed, however, that is the instance that I mentioned above previously where the tech stated they heard a noise similar to what I had explained but chalked it up to the oil level being low (which IMO was complete BS because the oil (not done by Jeep DS) had just been changed ~500 miles before this appointment and I check the fluid levels at least every other time we fill up the gas tank). Sorry for the rant but I actually do feel a tiny bit better after typing all of that out, at least until I get in my truck in about 15 minutes and hear the noise again...?

You can go back and look at the message I sent per @JeepCares request on August 29 to Steph. Never got a response and even followed up a few days later Sep 6 and no response! I was able to get the issue resolved with a great deal of legwork on my end and many trips to the dealer and none on Jeep's end! There are several tickets associated with the problem until it was finally resolved.

In the mean time, I lost a couple of months or so of the trial period as the system didn't work....

There is a TSB for this exact issue but only for 2021 and newer. Does that make any sense to anyone??? My dealer is more than happy to to do said TSB but they can’t because mine is a 2020. What the actual F is wrong with jeep? Make it so I can at least have the friggin tsb done to see if it actually fixes the problem by trimming the fuel curve or whatever. Is this really that hard? I don’t even know if other people have had this issue fixed by getting it done, but it sure does seem like the most logical place to start.

Mine is a 2020 and has been at the dealer (the other dealer, not the first one that I previously mentioned) since late last week having several warranty repairs done, including TSB 09-012-22. Not sure if this is the TSB you are referring to but it is in regards to spark knock/engine noise and includes the JT, years 2020-2022...I suggested this to the dealer by sending them a copy of the TSB after they agreed it was spark knock but said its due to poor quality gas, however, we only use Top Tier gas stations (not saying I couldn't have ever got some bad gas at one) and upon sending this they confirmed that they would perform the repair if that's how I wanted to proceed. Below is a screenshot for quick reference, as well as the link to the TSB. Hope this helps.

Thank you for the info. I already had this tsb done and it didn’t help or fix it. There is a tsb for 2021+ that is just a software update (I think) for detonation. I’m assuming it changes the fuel curve or timing or something.

Got it, good to know... Im trying to limit the length of my messages after i just scrolled past one of my previous responses which i would almost deem a novel but will add that the tech did say that they were aware of the tsb and had performed a handful+ of them and wouldnt guruantee it would be a lasting fix but said it would definitely be gone when i picked up the jeep but could return in ~ 3k miles, 20k miles, or never but kept telling me it was due to poor gas and nothing to do with the previous version of the PSV valve after casually bringing that into the conversation, which at that point i think the service mgr. thought i was a secret spy spying on Steallantis anyways i figured id take the repair under warranty since i would at least get the newer version part(s) and an "engine refresh" then will revisit when needed since it has been well documented (i feel my arrogance biting my ass in the future for some reason)..deuces

I also just reread your post and realizEd i may be joining your boat soon so ill be proactive by saying what the actual F'n F is wrong with thisf'n jeep...2BCont;d

Very simple way to see if there's "oil intrusion" into the combustion chambers.........
Check your oil level.
If you start out at exactly full after an oil change and then after 2,000 miles are down a measurable amount, that oil is going somewhere.
If like me - the oil level doesn't drop even after 4,000 miles, then you can't say it's oil related.
in order for oil to get into the combustion chamber in quantities to have any impact, it has to come from somewhere. So that means you have been losing oil from the crankcase.

This is all also very easy to prove or disprove in other ways - borescope the cylinders. Pull spark plugs as if there's oil consumption you'll see it on spark plugs. You'll see it on the valves and in the cylinders.

Thank you for the info. I already had this tsb done and it didn’t help or fix it.

They pulled the heads, cleaned carbon and replaced the PCV? Unlikely it's oil intrusion.

We've concluded that in most cases with manual transmissions it's not even "spark knock" (or detonation). The criteria just doesn't fit.

For the manual transmissions I go back to - "wind it up before shifting". Detonation can only happen at lower RPM.

I wouldn't disagree but jeep just tells me its spark knock which is normal but i explained THAT what is going on (if spark knock) is excessive and not normal so (respectfully) if all they can do is refresh my engine at this point with a chance of possibly fixing it than ill take it...I've been firing TSBs at them L&R and they're willing to do the work so currently I've all sorts of parts/software being replaced/updated on my jeep, which some might say is ignorance but I would lean more towards calling it documentation+proactive maintenance=something...not to mention the Chrysler 300S loaner car isn't horrible by any means either, especially since its my first encounter with Chrysler and the 300 but would definitely require the 300C if i went there fwew

They replaced the pcv with the new version and ran some carbon cleaner threw the engine. They did not remove the heads or spark plugs tho. I never had an issue with loosing oil. I change the oil more than necessary and it stays at the full line. I am slowly loosing coolant tho & they did a pressure test that didn’t leak down. So that’s awesome (sarcasm).
I have the 8 speed auto, btw.
If it is carbon build up causing the severe detonation that I am experiencing & I’m not loosing/consuming oil, then what is actually causing the buildup??? My opinion keeps going back to the fuel curve or timing. I could be wrong.
just cleaning the carbon and calling it good would not be a fix anyways….its just a bandaid. Just every pill a ‘doctor’ will prescribe.
They don’t care about the ROOT CAUSE.
Anyways, I’m shocked that you don’t know the TSB I’m taking about.
Thanks

@Scrubb84 - I have the 8-speed auto as well and have noticed coolant loss with no trace of it anywhere...FWIW, I recently noticed oil residue on my passenger side valve cover and camshaft position sensor (picture attached for ref). I only noticed it on the passenger side, as I didn't get a chance to check the rest of the engine bay before it went to the dealer for service.

I have that on both sides. Dealer doesn’t care as usual.
