My wife purchased an 2014 jeep Cherokee Limited and to date we have had no issues. The same year I purchased a Honda Civic Ex and also had zero issues. After seeing the new 2018 Jeep Compass one evening at our local dealer I decided to trade in my Civic for the a new Compass Limited because I wanted a 4x4 for the winters here in eastern Pa.

All seemed good with my jeep until around 300 miles when this strange groaning noise and vibration appeared around 30 to 35 miles an hour coming from the rear of the vehicle. There was also a single knocking sound when decelerating from speeds over 40 mph. I contacted the dealer where we purchased it from and they scheduled an appointment. The service tech took the Compass for a test drive and stated that he could not duplicate the noise so the service manager asked me to go for a drive with the tech. We went about about one mile up the road when the groaning noise appeared and the tech threw the auto shift lever into manual mode and the noise stopped instantly. He told me to head back to the dealership as he now knew what the issue was. He told me the Rear Drive Modual needed to be replaced. The service manager stated they needed to order the part and would call when it arrived at the dealer. The following week Monday, the dealership called and said my part was in and asked if I could drop it off and they provided me a loaner vehicle. Two days later I had my Compass back and all seemed good again until around 200 miles later when the same noise appeared. This was very upsetting to say the least but I know things happen! Another issue started, after washing the Compass the side monitoring lights would come on and stay on. Called the dealer and told them about the noise issue again and also the side monitoring light issue. They scheduled an appointment and two trips back to the dealer still having the same issues. We decided to open a claim with Jeep resolution Department. Our claim was assigned to Dana who called me the next morning and assured me she had the resources and technicians to fix my vehicle. We were given a case # and told she would keep us informed as to what she found after calling our service dept. Dana called back two days later and said the service manager stated to her they replaced the Rear Drive Module and checked the connections for the blind spot sensors. He noted to her that some connections to the sensors were resealed and they were unable to figure out what the issue was. He also stated to her that there was no fix for the Rear Drive Modual issue and would need to have a tech sent down to check things over to determine what was causing both issues. Dana then proceeded to tell me on the phone just to turn up the volume on my radio so the noise was muffled??? Really..turn up the radio??? I flipped and she quickly ended the call. I called her back the next day left a message and no return call from her. I called the dealer back several times to find out when this so called special tech was going to look at our Jeep and the service manager would not return my two messages. Really?? Go figure! Now I'm getting extremely.. p***ed off.

So now at 4000 miles and same issues. Two weeks ago we contacted another dealer and they scheduled an appointment for the issues with the groaning and vibration from the Drive Module. They stated to us that this problem was well known but a fix to the issue was not available. Our jeep was dropped off 2/12 and two days later the dealer called and said that our Jeep was ready to be picked up. They told me that they addressed an airbag recall issue and replaced the Rear Drive Modual but sadly the noise was still present when they test drove it. They stated to me that they spoke with a Chrysler representative who stated that they are waiting for a software update that should resolve the issues with the rear drive module noise. I was also told that the Drive Module that was replaced had metal shavings in it which was disheartening to find. No issue was found with the blind spot monitoring light issue we are having. Advised us to see when it happens to possibly find the issue. So we now know that the 2018 jeep Compass has a Rear Drive Module issue that the dealers and Jeep are aware of. Our issues are currently ongoing with no resolve. I love my Compass but we may need to pursue a full buy back from Jeep for a new vehicle. This is completely unacceptable from a new vehicle costing $34,000.

I, like many, have the CLUNK around 38 MPH. It is the AWD kicking in when the temps are around 40 or below. Do me a favor, go drive the routes you normally do and where you hear the noise. Then, LOCK the AWD and do it again. The clunk should go away. I've just come to expect it. Lets me know its working :). As for a grinding noise, I have no such thing. No signs of leaking anywhere under the Jeep either, as I just did an oil change and full inspection last weekend. My Trailhawk Cherokee always had something leaking by this point (9,000 miles).

This is even more disheartening - on top of the electrical gremlins we're STILL experiencing (haven't even had the car a day and it's throwing ESS error lights at me), its sounding like the 35-40 mph rear groaning is a serious issue. I'm in the process of lawyering up.

FCA insisted that the electrical issues weren't temperature related, but lo and behold, the errors came back the moment the temperatures dropped below freezing.

Oh - funny that you got Dana. She was assigned to me too. Didn't hear from her all week (Even though she said she'd be in touch MONDAY). Another rep eventually reached out after I blasted Jeep on Twitter.

Yeah you would think that someone at FCA would send out a memo telling people to never say things like "turn up the radio", "they all do that", "it was fine when we drove it" and so on. That is just so classic Chrysler. At least they aren't actually blaming the customer as they used to also do. Could be an amazing company if they just stopped being ****ing *******s. And fire Sergio, of course.

Simplest explanation for the clunk is just excessive backlash. Fixable I expect. My 2014 makes absolutely no noise going in or out of 4wd. Just to emphasize the point, I'm super sensitive to mechanical equipment and many times I've picked up impending failures on equipment long before the electronic monitoring or NDT inspections showed anything. It definitely makes no noise.

Mine does the clunk at 38 MPH when decelerating in the cold, AFAIK they all do because we have discussed this before in other threads here and the consensus is that it is a normal operating noise.

I hear mine doing it in the cold but I don't really care, or worry about it at all. To me, its simply the sounds and process of the rear axle being hooked up after being in 2WD at highway speed for some time. The rear driveshaft has electrically controlled disconnects at both the front and the back, as you slow down from highway speed the front disconnect re-engages and gets the driveshaft up to speed but the rear is still disconnected, it is at this point that you will hear the humming sound if the differential oil is cold. As you slow down further and cross the 38 MPH threshold the rear disconnect engages and hooks up the spinning driveshaft to the spinning differential. It is not unusual that there would be a small audible clunk as this engagement happens, these two parts are spinning fairly fast and have to lock into each-other at speed.

To me these sounds are not concerning at all. The vehicle is designed to operate as an AWD at low speeds and disconnect the driveshaft/rear end at highway speeds to be more fuel efficient. It has to re-connect the spinning parts when you drop down to low speeds again to go back into AWD and there is no surprise that a small amount of noise is associated with those actions. In my experience, it is nearly unnoticeable when the differential oil is warm. Possibly switching to a really high-end full-synthetic gear oil back there would keep the noise down a bit in the winter. If you really don't want to hear it when its cold out pop the 4WD button and the rear end will stay engaged, its not like it will really make a meaningful difference in fuel economy to most of us in an average commute unless you are driving at least 50 miles on the interstate steady.

I'm surprised the dealership even accepted it from you as an issue. Its a part-time AWD system in a borderline-economy vehicle, there can be some noise as it goes in and out of 2WD and thats fine, its not hurting anything. The vehicle has not failed or wound up stranded on the side of the road with an exploded differential. They've replaced what was probably a perfectly good rear end two or three times now because both you and the dealer think that metal gears spinning at high speed in cold oil should mesh silently? :dunno:

If you read my post you would have known it was a load groaning noise from a defective rear drive module. Not just the loud clunking heard while decelerating from speeds. Read the whole post before offering your own personal response.

I did read the whole post, but without any video or audio from you we don't have much to go on here except our own personal experiences with our Compasses. From what I understand, another perfectly normal low humming noise that commonly happens while cruising at medium speeds happens when the Multi-air II system is doing its internal EGR thing, that would be difficult to confuse with rear-end noise though I'm sure. At any rate, there are some normal humms, groans, and clunks that are typical of this vehicle and without hearing yours we don't know anything for sure but if it hasn't exploded and left you stranded on the side of the road then there is no proof yet that anything is or was ever truly wrong with your particular vehicle. If the dealer decides to go ahead with some warranty work they are going to say "oh yes it was blah blah blah blah blah" because for them if it turns out nothing was ever wrong then they don't get paid from FCA for the work they've done.

Rick, I've experience this issue with 2017 Jeep Compass I own and from what I've read in the Renegade forums, it's quite common on FCA 9 Speed engines. Mine happens around 35mph and makes a noise like if you are riding treads. The noise isn't there when the weather is AWD capable, under 40, but anything above 40, the sound is there. I haven't taken it to my dealership since there hasn't been a day over 40 here in Northern Nevada to replicate the sound. I noticed it a few days in Jan when we randomly hit 60, but since then, it hasn't been present. I've read on multiple forums that FCA is working on a software fix, but nothing as of yet. Let me know if anything comes of your issue.

Julio, I sent Julie from jeep cares on here two messages and she replied to the first message and then I did not hear back from my second message to her. Not sure what to think about this whole ordeal.

I'm in the same boat as you. I've contacted Jeep and they are aware of the issue, but they have no time frame on the fix. Although it is a simple frustration with the noise, I find it hard to believe that a fix is not available. They've had issues with the Renegade 9 Speed engines for two years now with that same noise. It's a similar engine in the compass. I truly hope that they find a solution to the vehicle, otherwise I'll weigh my options.

Probably because nothing is actually broken :dunno: stop being so paranoid, its a simple low-cost part-time AWD system that makes a little noise in certain circumstances. Nothing is broken, nobody has been stranded on the side of the road from this.

You guys would have HATED having a four wheel drive vehicle from the mid-nineties or earlier, some models could only be put in 4x4 at a stop and they almost always had a front-end growl or humm once engaged. Worked just fine though, and people knew the noise was normal.

Is anybody ever going to record a video of this alleged problem? Then at least we would know if the normal operating noises I hear are the same ones you guys are referring to. Its not impossible that something is wrong with your particular vehicle but without actually hearing it we can only guess our cars are doing the same thing.

Listen up! If you choose to spend your hard earned money on something that is not operating as designed that's your problem. I myself am not the kind of person that rolls over and accepts what I've been told as an acceptable answer because someone who has no clue of what the issue is with the vehicle is gives me a line of BS!! So for the last time keep "your" opions to yourself. No one cares what you think.

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.

Uggh, calm down, I know my posts are sometimes worded strongly and come off as condescending but believe it or not I don't want to piss people off. I just have a natural reaction thats hard to control when people come on and post

"blah blah my car makes a noise and I don't know what it is and even though it drives 100% fine and has not broken or left me stranded I'm convinced it has some problem! :nosepick: "

I just want to see proof that there is actually an issue. Thats all. A bit of humming and a clunk from the front or rear driveshaft disconnect is not an issue as far as I know. The reason you didn't experience it right off the bat is probably because it wasn't cold enough when you bought it in the late summer or end of fall but then it got cold it started doing its winter mode stuff. We don't have a ton of concrete information since FCA is rather tight-lipped about the programming of their vehicles but we DO have the aggregate data from bunches of forum members here and with our cousins the Renegade and some of the Cherokee models with the same engine and transmission, seems like tons of people in cold winter states report observing this sound and as of yet nobody has seen any actual issue as a result.

At this point, we aren't going to get anything real useful from you it seems. You don't seem to want to make a video or do any diagnostics yourself, you pretty much just want to b**** and moan about it so ... we can't help you. But we can still post here so that some other person who buys a Compass and hears the noise in the winter and gets curious doesn't get needlessly freaked out when he or she googles around and finds your thread here. When there is proof that there is an issue, then we will have something to talk about. In the meantime, I reserve the right to post critically of alleged issues on a vehicle that has not actually broken down or malfunctioned in any way.

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). And the dealership is probably willing to soothe your ego and say "oh yes there is something wrong" because they get paid from FCA to work on it so its money for them, and if they get halfway into the job and realize "oh crap, its not actually broken" they are not going to want to admit that because then FCA will not pay them for the work, and obviously neither will you, so they lose and they don't like that. They will label perfectly functioning parts as "broken" and replace them all day long to keep the warranty money rolling in and the customer placated. I'm just sitting back wondering what they are going to tell you after the third round of major service happens and it still works exactly the same... :rolleyes:

Anyways, again, I do not mean to insult your intelligence or make you upset. I try not to write abrasively but sometimes it happens. I don't have all day to sugar coat things and it doesn't come naturally to me. But I hope if the dealer replaces yet another part and the same sound continues you will at least think about how many thousands of these are driving around every day, many people reporting the curious sound but essentially none of them have left anyone stranded as far as we can tell and they probably won't based on the track record of the Renegades with nearly exactly the same drivetrain so... give it a chance.

If or when your Compass actually blows out a differential or the PTU unit and leaves you stuck on the side of the road, feel free to come back here and scream and holler at me all you want. I'll apologize then. In the meantime try to keep that blood pressure down and enjoy your (probably perfectly fine) Compass ;-)

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.
