I am glad that I found this thread. It looks like, that this issue made it over to Germany too. Had may car already at the dealership to check the transmission with no result, the noise is still there. Now I was able to advise the dealership to look at the 4 WD system. Our European uConnect 8.4 has an app called Jeep Skills, it shows a real-time graphic of the drive train. This grinding noise comes right at the point, when the rear axle kicks in.

Thank you guys for this useful thread!

Here is what I see and feel the clunk at around 35-40 MPH in cold weather is pretty much normal but noise from the rear PTU is something I would be concerned with especially since the dealer has made the comment that it is a known issue and a software fix is supposedly in the works. This says they know there is an issue with at least some number of vehicles. Then the fact the dealer found and was concerned about metal shavings in the unit. This means very likely whatever software issue going on may be damaging the unit. This issue is a big deal and if it were mine I would be getting pretty angry as well.

Yes often 4x4 vehicles make all kinds of weird sounds and it gets worse with AWD or automatic 4wd systems. However there are sounds and issues that fall out of the norm. When this happens it needs to be dealt with as it is very possible damage may be being done.

If I were you Ricksabdl I would be holding onto every piece of documentation you get. I would be on the phone with a Jeep caseworker and expressing your concern that this issue may still exist with your Jeep after your warranty is over and if they plan on extending your warranty at least with this issue until it is fully resolved. They should also replace your PTU when and if the software fix is done as since one PTU showed damage from this issue there is no reason to think the new PTU has also not been damaged and be a issue later down the road.


If you don't get the answers you're looking for I would start looking into your states lemon law. Search out others with this so called well known issue and getting statements from them may help. If you can't find a lot of people with a Jeep Compass or Renegade with this issue that goes a long ways towards saying your Jeep was broken right out the gate. Personally if I were Jeep I would be considering vehicle replacement if they cannot guarantee a fix in a reasonable time frame.

How a company stands behind their product says a lot about them and leaving someone hanging with a faulty product will have an impact on their sales. FCA does have a lot of negative press at the moment though I feel it is not earned they still need to show they will stand behind their vehicles more than ever right now.
Bingo, Finally an intelligent individual responds. Outstanding response Chris Jacobs!! You read the post and understood with total clarity what the major issue and concerns were. I must applaud you Sir! ����

Not like the other rocket scientists who post this total BS, You think that you are a certified technician but in fact you're commenting on things you have no idea what you're talking about. I told you to read the whole post. Did you? Answer ..No!!! Instead you post this crap. You can take you hard earns money and shove it for all I care.!!

"We have every right to post here so sorry to piss you off but you don't get to decide who can post and who can't. I realize I'm not doing the best job of reassuring you that your car is fine (I swear thats all I meant to do) but I don't get paid for sharing my knowledge and opinions so too bad, so sad, this is what you get buddy.Now you are too mad to even give the idea a fair consideration (that your car could be fine)."

Brilliant!!��

Not sure why the question marks in Black they were supposed to be thumbs up emojis sorry Chris!

The ones at the very bottom were thumbs down emojis.

It's all good I have a hard time figuring out how to work some forums for a bit and goof up all kinds of stuff.

I have been driving 4wd vehicles for a long time now. In fact right now there are 5 vehicles in the driveway all 4wd. I have been on some sort of forum for sometime for given 4wd or general for all 4wd vehicles. I actually understand arudlang's post if they have been part of other forums dealing with 4wd vehicles. It is very common for someone that had never before owned a 4x4 to jump on a forum being very concerned with noises and actions of their 4x4 that they had never experienced from their 2wd vehicles. Some can get upset when they have convinced themselves they have a bad problem when in fact nothing is wrong. I have actually seen people get so angry over a normal operation they did not like that they sold their 4x4 swearing they will never own another 4wd vehicle.

Since I am not a forever owner of 4wd vehicles I think I am just calmer about trying to help people understand what things are going on and when to be concerned. I remember my first 4wd was an 86 lifted Jeep Cherokee XJ and it made all kinds of clunks and noises and jerking in 4wd. Luckily I had gotten it from a friend and had spent some time riding around in it and asking about these things. If not I'm petty sure I would have been convinced the thing was trying to tear itself in half. So I have been there worried about what was normal and what was not.

Then we have the issue that each type of vehicle has things unique to them. We have a 4x4 Suburban with an auto 4wd mode. It works great most of the time but the rear is allowed to slip too much before the front kicks in. On the road in the snow and ice where the front is near the same speed as the rear it is fine. Get in the mud where the front might be stopped or near stopped and the rear spinning the auto 4wd violently kicks in the front to the point your sure something broke. Solution is very simple in these conditions don't use the auto mode and go to 4wd. When going into 4wd mode you get a little clunk moving the first few feet forward as the the front kicks in then it is done.

By contrast my 03 chevy Tracker has the sweetest 4wd I have ever owned. It does not have an auto mode but moving between modes including low range there are no clunks at all and I have driven at speeds up to 55 in snow and ice without any vibrations or noises. The only time it has complained on is tighter turns on drier pavement and that is 100% normal for any part time 4x4 so when conditions look like 2wd is all that is needed you have to remember to shift back to 2wd.

Now so far a bit over 1000 miles our Compass has been great. In fact I have not even heard or felt the clunk of the driveshaft kicking in or out in 20* weather. But I suspect as it keeps breaking in that will loosen up enough to be noticeable. I did pick up on some minor noise and vibration at certain speeds on certain road road surfaces. I was quickly able to tell this is coming from the Wildpeak tires the Trailhawks get. These tires have the road manors of a much more aggressive tire it does not bother me knowing what it is but someone else might be concerned not knowing this.

I fear in your case the PTU for some reason is not allowing for enough speed difference between front and rear axles in the turns or to account for pressure that can build up from small differences in axle speeds while operating in 4wd. It is not enough to cause binding just complaining in the form of noise. This also will increase wear on certain driveline components this could account for the metal shavings. I have seen these types of things on part time 4wd systems that were run on high traction surfaces by people that had no clue they should not do this. I have even seen u-joints that blew out and ring and pinion gears break teeth in extreme conditions. But often it is just greatly increased wear in one or more places in the system as parts are forced together harder from the pressure that build up till a tire slips to relieve that pressure then it starts building again.

But keep in mind I'm just an old shade tree and these Jeeps have a pretty complicated 4wd system. I think it is using wet clutches to vary how much if any power is transferred front to rear (I'm not 100% sure on this). The computer should adjust the slippage as needed to stop driveline pressure from building when the system is in a 4wd mode. It is possible something in the software in some of these Jeeps is not doing that correctly. It is also possible there could be a mechanical issue with how the system does this. It is even possible if it mechanical as parts wear and break in the issue resolves itself.

My worry in such a case is how much damage might have been done in this process that shows up later down the road. If you love this Jeep and want to keep it outside of the warranty period I would look into one of the extended warranties FCA offers. If you explain your concerns they might even give you a better deal on an extended warranty.

If we continue to love our Compass as much as we do we will buy the lifetime unlimited warranty with a $200 deductible as by the time my wife is ready for a new vehicle I may want to keep this one as a toy. :)

😂 LOL, America first! For sure, they will fix your cars, before they fix ours. We are always behind, especially if they have to adapt the fixes to our Diesel models.

Chris, this is what is so frustrating. The new PTU had only 1400 miles on it before the techs found the metal shavings in it. It starting groaning at about 100 miles after replacement. The tech told me over the phone how disheartening it was to see the metal shavings in the unit. As we speak the thing is still groaning and vibrating. What a shame as my wife's 2014 Jeep Cherokee is quite and has had no issues what so ever. That was one of the reason I went with the Compass in the first place.

I had a few minutes to goof off and see what I could find relating to your problem. Not only to see if I could help you and others but I also like to be aware of any issues I might see at some point. As you can guess there simply is not much out there for our 2nd gen Compass they are just too new and not enough of them on the road with many miles on them. However the Compass sister vehicle the Renegade has been around a bit longer. Many of these share our complete drivetrain and chassis so a bit of searching under those yielded the thread below on another forum and it warrants reading all the way through as there are references to a PTU software update when available. There are also some tips that might help you determine if your issue relates like shifting to 4wd when you hear the noise to see if it stops. If nothing else if your issue is the same you know if it is that common of an issue. :)

I too have had the moaning noise at 40mph,but if I disengage traction control it immediately goes away. So why is this not repeatable by service tech?
FCA is also very un sympathetic to the issue. There is a known issue but there is no apparent fix yet. My first trailhawk lasted 7days and was replaced by the dealer. Now I am growing tired of the “ cannot duplicate” statement from the dealer.
I just might be “ turning up the radio “ in a competitors vehicle.

Sadly if you spend less than 80-90k on a vehicle most play this kind of game when issues come up. This has become worse with vehicles that have so much computer involvement from bumper to bumper. Now they often try to come up with a much cheaper software fix to even mechanical problems.

It really bothers me when manufacturers start saying something is a problem without a fix like this. For a mechanical mind it is just this simple. If not all the units are having an issue only a small percentage go through the units having an issue and see what is different to those without the issue. If it is a software issue compare the software to one that does not have the issue and fix it. Mechanical issues resolve the same way.

So the way this feels is they know they have a number of Jeeps with this issue and their solution is to make a custom software to cover what might might would be an expensive mechanical fix. In some cases this might be ok in other cases you might be affecting vehicle performance and longevity.

I know someone with a small ford car right now it is on it's second automatic transmission and still having issues. They claimed software issue and now the car stretches out 1st gear barely stays in 2nd then jumps to 3rd with a huge lug to the engine till it is going fast enough to be at the right RPM for 3rd gear. Going up hill or passing it does the same thing in reverse and tachs hard in 1st. The rest of the gears are fine. Now they are saying that is the software fix and is considered normal operation. My guess is there is something about the transmission operation in 2nd gear that is the problem so they programmed the computer to use 2nd gear as little as possible

This is the kind of stuff that made me almost not want to buy a new car. It is just a dang if you do dang if you don't thing. Had a good factory backed warranty not been available I might would have just bought an older simpler vehicle and just rebuilt it! :)

I am a bit confused. Is the issue a "clunk" or a higher pitched humming around 40ish MPH? The OP was talking about humming others talking about clunking. Is this the same thing or different?

I will admit I am a bit deaf (too much gunfire from an early age, before Ear Pro was popular), and I don't think I have ever heard a clunk. When I'm in 3rd and cruising at around 40ish the engine does sound a bit hummy with a different tune, and it seems to be come and go. I don't hear it all the time, but that could just be me. I don't know if this is the issue you are talking about here, or it's just my poor hearing.

I agree though, if you aren't satisfied with something you should not settle. Demand satisfaction!

Just would like to throw out there, that dealers are bull****ters and will tell you all kinds of things to make you happy. A large chunk of the time they have no idea whats going on. Being that no vehicle has actually ever broken down from this alleged "issue" so far, its still within the realm of possibility that they talked themselves into a corner due to their ignorance. They admitted to an issue early on and now they can't easily backpaddle on that without turning the customer's ire against them, which leaves them in a tough spot and they are most likely going to try to continue to deflect the blame to the next level up (FCA Corporate). That way the customer still thinks the dealership is alright and will hopefully continue to buy other vehicles from them.

Sure they did. Or, at least, they claimed they did.. :roll: They have a lot of good reason to *say* that there were shavings, because as I mentioned before they are potentially backed into a corner on this one. FCA won't pay for them to replace a perfectly good PTU or differential, they MUST find something, anything wrong with it in order for them to get paid out on warranty for the parts and labor. I'm sure there is no proof of these metal shavings. By far the easiest thing to claim to sneak by on that one because the proof goes down the drain (well, into the oil recycling bin). No actual broken gears or anything like that to send into FCA corporate to have inspected. See what I'm saying?

"major issue" :roll: Just how is it a "major issue" if not one single vehicle has actually failed/broken down from this? You are just accepting the responses you want to hear and absolutely throwing all other reason and logic out the window. Something like 50 THOUSAND of these vehicles are roaming the roads. None of them have failed from this "issue" yet, not even yours, you just hear a 'noise' and cling to an unsupported conclusion. The dealer replaced one major part for you and it worked the same. Hmmm, almost like it was working properly as expected to start with. I gave good reasons why the dealer would say "oh yes we found an issue" even if they really didn't, and you just don't want to listen.

Now, if all of a sudden over the next week 5+ forum members chime in with reports of grenaded differentials or PTUs, then and only then will there *maybe* be sufficient evidence for a logical person to start contemplating that the noise is an indication of any sort of issue. Until then, I remain unconvinced and encourage everyone else who is watching/reading and wondering about their own vehicles to use their common sense and draw their own conclusions. wink:

And you know all of this how??? EXACTLY... Just because YOU feel as though nothing is wrong and your in denial that a problem exists with the Compass PTU doesn't mean we the consumers who actually own the vehicle will settle for "It's probably OK or nothing is wrong" as your twisted thinking seems to have clouded your judgement as to what is just good enough for you. I myself expect 100% for what I pay for not 80%. Are dealers perfect ..No, but no dealer is going to tell you they found metal in the PTU for no good reason. You clearly are delusional. I told you before I don't care about your personal opinions. Go troll on someone else's post!!

They admitted to an issue early on and now they can't easily backpaddle on that without turning the customer's ire against them, which leaves them in a tough spot and they are most likely going to try to continue to deflect the blame to the next level up (FCA Corporate). That way the customer still thinks the dealership is alright and will hopefully continue to buy other vehicles from them.
Yes dealer sevice departments can be full of crap and tell you anything but not all of them I have found more than a few that know what they are doing and want uphold the reputation of the dealership and the brand after all it in their best interest to help keep people loyal to their service department, their dealership and the brand. The fact that I have found more than a few post talking about this issue. I have found reports of the rear drive PTU and transmission replacements not only on the Renegade but a few Compass as well. Not all these post went into the how and why these units were replaced just that they were.



Sure they did. Or, at least, they claimed they did.. :roll: They have a lot of good reason to *say* that there were shavings, because as I mentioned before they are potentially backed into a corner on this one. FCA won't pay for them to replace a perfectly good PTU or differential, they MUST find something, anything wrong with it in order for them to get paid out on warranty for the parts and labor. I'm sure there is no proof of these metal shavings. By far the easiest thing to claim to sneak by on that one because the proof goes down the drain (well, into the oil recycling bin). No actual broken gears or anything like that to send into FCA corporate to have inspected. See what I'm saying?
Now I'm wondering did you even read the first post and understand it? The metal shavings were found in a PTU that was replaced. You can bet the defective unit metal shavings and all went back to FCA. Now what happened after that is the question. Most likely it was torn down and inspected,fixed and ready to go back out as a reman unit. If in this process they see a common failure a report goes to the engineers to try to figure out why the units failed and what updates or changes can be made to these units and if there is something that can be done to protect the other units out there in use. For example this can come up as a TSB to change to a revised lubricant or information given to customers for a revised service interval. This actually happened to us on a Honda CRV where sevice interval on the rear diff changed drastically from what was in the owner's manual.



"major issue" :roll: Just how is it a "major issue" if not one single vehicle has actually failed/broken down from this? You are just accepting the responses you want to hear and absolutely throwing all other reason and logic out the window. Something like 50 THOUSAND of these vehicles are roaming the roads. None of them have failed from this "issue" yet, not even yours, you just hear a 'noise' and cling to an unsupported conclusion. The dealer replaced one major part for you and it worked the same. Hmmm, almost like it was working properly as expected to start with. I gave good reasons why the dealer would say "oh yes we found an issue" even if they really didn't, and you just don't want to listen.
Again we don't know know how many vehicles are effect but enough to see people talking about the same issue. Also many have been told it was a known issue and the fix is in the works. If there was no issue with how some of the units are operaterating they would not be working on a fix. The only time a fix is needed is if something is broken unless you're a dog heading to the vet! The big question here is how broken is it,what is broken,what is the fix going to be. I say what is broken because above I mention transmissions that were replaced. I'm going out on a limb here but some of the 4x4 components are inside the transmission. A problem with those components could be stressing the rear PTU causing the noise and even increased wear.

Now, if all of a sudden over the next week 5+ forum members chime in with reports of grenaded differentials or PTUs, then and only then will there *maybe* be sufficient evidence for a logical person to start contemplating that the noise is an indication of any sort of issue. Until then, I remain unconvinced and encourage everyone else who is watching/reading and wondering about their own vehicles to use their common sense and draw their own conclusions. wink:
Failure does not always come in the form of catastrophic failure. I have seen enough searching mainly in the Renegade forums to see that yes this is an issue FCA is looking at and trying to fix with a software update. How else would unconnected people post that this is what they were told. Another interesting fact is that sometimes some failures are related to a given use or set of circumstances. One that comes to mind is an issue with the Pentastar engine and an exhaust manifold noise. It was determined there was a direct relationship to given circumstances that cause the problem with some engines. They never disclosed the circumstances they the issue would occur under but they were fixing them.

Look no one is telling people to avoid these Jeeps because of it or that everyone that owns one will have this issue and need to run to the dealer to fix something that most likely is not broken on their Jeep unless they feel/hear these same vibrations or sounds. We have a rightly frustrated owner trying to figure out if they are going to get stuck with a problem vehicle and trying to find answers.

I read through the posts you linked to at the Renegade forum, and within their forum links to other discussion threads they had. I don't know what you read that makes you think they are actually working on a "software update", I don't see anything about it other than vague references people got from their dealerships that all came with words attached like "maybe" and "I think they are".

What makes me shake my head is that obviously if there is some mechanical issue it cannot be "fixed" with mere software. So whatever you guys are dreaming is going to happen, that the dealer is going to plug in a computer and "fix" this, you are going to be dreaming for a very, very long time.

I also did not interpret any of those posts over there as having any dealerships actually confirming it is any kind of issue. The dealerships seemed to have told customers they were 'aware' of the sound and people have twisted that into "aware of an issue".

What I read on that link to the Renegade forum was nothing more than a handful of people saying "yes, I noticed it too, but my vehicle works just fine". I still think that is all there is to it. Everyone seems to be able to observe it, they all do it pretty much from day one, and nobody has had an actual failure.

I still don't buy the metal shavings bit. I already said why they would have good cause to lie about that, the dealership does NOT want to pick up the tab for the parts and labor to change that unit. FCA is too large of a company to inspect one allegedly bad unit, none of their engineers would be directed to investigate this unless dozens of bad differentials or PTU units starting piling in rapidly. A one-off replacement for one customer is going to slide under the rug.

At most, I think maybe they will hear enough chatter about it that they actually get an engineer to write up an explanation for the noise that will trickle down to the dealers to give to the customers and I doubt you will ever get much more than that.

In the meantime its just a discussion here. You guys only seem to want to explore one possibility I would like to keep pointing out the other possibilities and the holes in your thinking.

I don't have much input in this thread, the noise is not something I have noticed, but I don't really have an ear for that. But besides getting angry at some random person on forum which just plainly isn't a healthy thing, I should note that the point he was making and your complaint is that you have assumed that it is not operating as designed. It may not be working as you expect it, it may not be running as you demand it, it may in fact be not running as designed and you should look as you are into a solution. But just because you have assumed that it is not running as designed doesn't mean that is the case.

Really?? Read the original thread before commenting. What part of noboby cares about your personal Non professional opinion don't you understand??? Random comments regarding nonsense and personal opinions mean absolutely nothing to me so keep them to yourself!! If your having an issue with your personal vehicle and choose to do nothing about it thst's your problem and your money to piss away not mine. I'm not here telling you to just deal with it.
Well I was trying to be civil and point out that some of the displaced anger at other posters might because there seems to be an unwilling to see that "that's not what I expected" does not always equal bad or broken. Maybe bad in the sense that if you knew the car did it (in this case make the noise) you might not have purchased it and I can understand your frustration. But that doesn't mean bad like this isn't working properly. Not an engineer so I can't tell you if it is broken. I wouldn't want to guess on something that is this sensitive which is why I wasn't really willing to comment on the direct comment itself. I do notice a 30-45 miles per hour an increase tension and increased noise but I don't know if this noise is what your talking about, sounds like normal increased tire noise with the rears now actively seeking traction. But like I said I don't know if that related to what you hear because the everyone ears and sensitivity are completely different and not a single person has uploaded any audio of the issue. Another reason for me not to comment on the issue.

I have had my rear diff replaced but it was for an electronic issue and have posted that issue in the issue thread. So I am not even saying they can't be bad. I did have a bad one. Just saying without a more definitive example of the noise you are probably going to get more of the "This might not be an issue" posts because it is natural in this car that does 4 wheel at city speeds to make an increased noise and if that increased noise is what you are hearing while "not acceptable" to you might not be an actual issue.

What ever is going on with our PTU is not "normal" We test drove two Compasses and neither one made this loud groaning noise and vibrated around 35 to 45 mph. If the noise would have been present during the test drive in either vehicle we would have never purchased it and neither would anyone else. The groaning is loud in the stated speed range and the vibration can be felt through the accelerator pedal. Two prior dealers are telling us that a software update may resolve this groaning and vibration issue by changing the way the vehicle shifts. Is this software going to possibly cause other issues? Who knows. I know for a fact if someone else owned and drove our Compass with the way it groans, vibrates and carries on, they would be very unhappy with this vehicle. If you guys are happy with your vehicles I'm glad your satisfied. We are not! And yes, it may take one or two years to get this resolved through a new model year. Who knows.

Fair enough Rick, if you drove some others ones and they did not make the noise then its a reasonable conclusion that something is definitely wrong with the one you got. I'm always thinking of mine which does make some 4x4 noises in certain conditions but whatever is going on with yours is probably different and definitely needs to be fixed.

If I get some free time I'm hoping to jam my go-pro under the car and take it for a drive and try to get the 4x4 engagement noise on camera. I am curious to see if it isn't maybe the sound of the driveshaft getting suddenly engaged and going from 0 to speed, would also like to narrow down whether its my front or rear disconnect that engages last. But thats just out of curiosity, I don't think it will help with your car's issue. I hope they get it fixed for you.

Arud, I definitely understand where you are coming from. For a while I considered the vehicle was making normal noises, and it might be. I just want to be sure it is. I would like Jeep to acknowledge that it is normal noise. However, because we hear some vehicles have no issues at all, and some do, it makes it difficult to address it as normal noise. Renegades where facing these issues as well, and I understand that it involves the disengaging of the rear axle, but why do some vehicles not experience this riding tread sounds. As my understanding is as well, some Renegades share engines with some Compasses. When I test drove both the FWD and 4x4 at the dealer, neither sound was present as they were under the 40 degrees mark. I've experienced this noise now that warmer weather has been showing up, granted the vehicle will ride FWD more often. However, my brother while shopping for a vehicle, test drove a 4x4 2018 Jeep Compass, Sport like mine, and it made no noise, SLC was 56 degrees at the time, and test drove a 4x4 2018 Compass Latitude, noise was present.

I'll eventually get used to the noise if I know that it isn't damaging my vehicle. I truly love the design of the Compass and it feels very comfortable in my hands. If it is a simple software adjustment to fix the noise, fine. If it requires some adjusting, great as well. I just want to know that the vehicle I paid $24k for, is not going to wear down early because of this issue. I will give you this, a Renegade user in their forums noted that after driving his vehicle for 8,000 miles, warm area for him majority of the year, the noise went away on it's own. I just want to make sure that my vehicle will last me a while and won't break down due to this issue

Totally understandable, we had a weird weather snap here last week and mine was doing the humming and metallic POP a bunch. It is weird, and I too would not mind Jeep chiming in and signing off on it as "normal" or not. But its under warranty and honestly I'm thinking of maybe springing for a grand cherokee when the lease is up so knowing that I drive it with a "meh, if it blows up it blows up, not my problem" attitude :p
