Just an update on my 2nd shop visit. I typed up a description of the Renegade Rumble - how to replicate it and stop it and gave it to my service agent when I arrived. They worked on the car for the morning as I waited at the dealership. After 3 hours or so they tried the same bait & switch hustle they did the last time I was there - my original service agent was ‘at lunch’ so the reinforcement lady tried to settle me up by telling me it was my tires making the sound. I didn’t even stand up and asked her (in front of other waiting customers) if my service agent had written any of the document I brought on the paper for the technicians - she said no (and started sweating lol). They ‘worked’ on the car for a few more hours, ran 2 powertrain updates, and finally admitted (on paper) that the sound was still there and they could only wait until Jeep issues a fix.

Considering Jeep hasn’t fixed this design flaw on all previous models, I wouldn’t hold your breath. I immediately started browsing the Toyota lot.

Customer care has reached out to me but I’m not expecting much - probably just some poor customer service agent that is gonna call and act surprised and concerned about the issue.
Hi NewBernRenegade,
We are sorry to hear of these ongoing concerns with your vehicle. Our team understands how frustrating multiple dealership visits can be. To clarify, do you currently have an open case with Jeep Customer Care? Please send us a private message with more details.

Hmm. 4 cylinder engines have a beat tone/frequency to them. This can cause vibration as the sound impulse is really powered by the combusting fuel, so the energy input is pretty significant. It seems the renegade/2.4/9speed combo puts that beat just above the target efficient RPMs. I have noticed this slightly boomy slightly grumbling sound since day 1. Putting it in a forced 4wd mode elminates it because it loads up the engine quicker, which means that where the beat tone happens is moved. Since it seems to go away, I'm assuming it is moved to something between idle and ~1500rpm which is a span the revs move through pretty quickly.

I suspect 1.4T engines and the over seas offerings don't have this issue because they don't get this drivetrain combination.

The AWDF system with it clutches is also kind of noisy. Similar to late 90s audis with torsen diffs.
A question if you don't mind, raz-0: Am I correct in assuming that if my hearing was good enough I might detect it in my 4X2 2.4/9-speed Rene driving at just above target RPMs, but I would have to be going > 60 MPH and in 8th gear?

update on my rumble issue.
the dealer has had my 2016 4x4 ltd manual renegade since last OCTOBER they have tried various updates and investigated the transfer case and box, now they have ordered a new gearbox from italy. Jeep have sent specialist engineers on three occasions but no one can sort this issue out.

I have no faith in the car or Jeep anymore and am beyond fustrated, to make matters worse the only number i can call jeep directly on is in Milan, i live in the UK.

I have a 2014 model Renegade with a 2 liter diesel engine and manual transmission. Last year my garage replaced the rear transmission due to the rumbling noise. They first disconnect both rear axles and the driveshaft, and turned it by itself and came to the conclusion that the right bearing was going bad. Can't replace only bearing so it was expensive, but that fixed it. Now after 10 months on the new one it is starting it again, same procedure, axles and drive shaft disconnected and same, right side bearing making noise. Waiting on guarantee ! The dealer implies they don't know of such a problem.

I bought a 2015 Renagade 4x4 manual last September. I am getting this same problem. If I'm driving at around 30 mph I hear a servo noise (assuming rear wheel disconnect) then the car starts to rumble. Sometimes you hear the servo and the rumble doesn't start. It's like the servo is stopping apart way through its cycle but not every time. When rumble starts you can stop it either by turning of TC or pressing 4x4 lock Has anyone with is problem succeeded in having it fixed ? I have had various things done under my extended waranty now they tell me it is a normal noise of the car. RIDICULOUS

Well you can't argue the fact that it is normal. I think every single one with 4WD has this noise at varying degrees (whether or not the owner acknowledges it).

On my 2015 the noise/rumble is barley perceptible unless you know when to listen for it. If the radio is on at any reasonable volume it will not be noticed. How obtrusive is it in your Renegade?

It varies sometimes it is hardly noticeable other times it's a loud rumbling. What I don't understand is why it goes when you turn off the traction control. Is it the ABS or the rear wheel disconnect ! Is it something to do with the wheel sensors ! I've had the ABS pump changed has anyone had the wheel sensors changed or reluctor rings?

My roads are so pot-holed/patched around here, there's not a smooth stretch of pavement where I could stand chance to feel the vibration without truly concentrating on it.
I guess it worse in some vehicles, and some owners are more sensitive to it (and more concerned about it) than others. For me, based on what I've learned about this topic on this forum, it's not worth my time to bring it to a dealer. They'd probably just do some transmission computer upgrade and screw up my perfectly functional Renegade.

If it's not bothering you, I'd ignore it. I've put 36k miles on it that are almsot entirely in the range where it happens. SO I notice it a lot, but I ahve had noreliabiliyt issues related to it. Other have travelled more miles, probably engaging the behavior less, and no complaints of failure.

I've jsut chalked it up to it being the sound of the AWD system. It wouldn't be the first. An audi a4 with torsen diffs made all sorts of AWD nosies in use.

Also, having done some traveling with my renny, there are some areas I visited where the natural topography and traffic conditions really didn't set it off much.

Hi. I have been told that my 2.0 Ltd 4wd goes into 2 wheel drive at around 30 mph is thus true as I have posted my rumble noise at around 30mph and my cars been with the dealer since last Oct trying to correct it. The original mechanic said my renegade is 4wd up until 70mph! Someone is not telling the truth. So I am being told that the rumble noise that everyone is experiencing is just the rear disconnect happening at 30 mph. Can someone please shed some light on this please.

Have you got ant potholes very hard..does sound get better or worse when you turn left or right.. if it's get worse in only one direction as you drive it could be wheel bearing...I hit curb at 40 mph and knocked it all out of alignment and damaged my wheel bearing..not covered under warranty because I caused the damages..

They both are telling the truth, kind of.

The renegade's system, when not forced into 4wd mode by the driver, will follow it's algorithms and sensors in auto mode. By default, when starting from a stop, all wheels will be driven. Then at some speed it will ago to 2wd. That speed is supposedly ~30mph and where the 30mph noise comes from. When that happens, the wet clutch in the rear drive unit is supposed to be fully disengaged, the noise comes from that process being done incorrectly for the vehicle and the only report of the noise being fixed was due to FCA engineers dropping a custom calibrated firmware on their renny.

The AWD system, even if forced into 4wd mode, will cut out at highway speeds for economy and durability. I have heard that happens ~50mph. The tech says 70mph. I suspect it is less than 70mph or there wouldn't be much in the way of gains in economy.

The noise being discussed here is not a bearing.

My Renegades rumble has been fixed, it was in the dealership from last October to last week.
the work carried out:
In order..

• Transfer box motor
• Transfer box
• Rear diff unit
• Rear diff software (via Italy)
• Gearbox

• Awaiting fitment of a prop shaft

• Have re- ordered another transfer box and rear diff and transmission control unit at Jeep Technical request

that was in may, the car is now rumble free and im not really sure what fixed the problem and dont really care, all i know is that after years of owning a lot of different jeep models im done with the brand and will be trading the car in at the earliest opportunity.

Good luck with all your rumble issues i hope it all gets sorted out.

I wanted to throw my 2 cents in. I have noticed what happens is sometimes it gets stuck in 5th gear and doesn’t want to shift down without slowing down further until the point it half risks stalling perhaps, then it will shift down to 4th and then 3rd etc. Every time it happens I pop my 2018 Latitude into “manual” and yep its “stuck” in 5th again and shift it down and pop it back over to normal. Doesn’t happen often, usually its one of the state highways that in certain cities become a street then back to highway so I have to slow way down once I enter that city/town, I think the Renegade just goes “what the frick?”

I would if I had video evidence, as i know my dealership of purchase would most likely shrug me off as “our mechanic can’t duplicate the problem”. I know how it occurs almost for certain, but would need lights to agree to be certain.

I'd have to see what you are talking about, but I don't think it's broken, just the 9 speed and the firmware fixes to avoid certain problems. For fuel economy, it will try ot get to 5th as soon as possible. Because the 4-5 shift is one of the ones with a dog clutch, it takes longer. Based on owner complaints some things were changed about the firmware's shifting strategy. A couple of things that it definitely does differently now is if it detects deceleration, it avoids a downshift for longer, especially the longer shifts that involve a dog clutch, so that you are at least in a gear if you get back on the throttle. It'll also hold gears longer before upshift under certain conditions compared to early revisions.

In general, it has always been willing to get into the area of lugging the engine to hit the right numbers for fuel efficiency. I suspect owners would be happier if they just bumped up the target cruising rpms a bit and avoid getting into that near lugging zone. But I suspect that would worsen their problems with the EPA.
