Noise when braking 2014 JKRU

I recently bought a new 2014 Jeep Wrangler Rubicon Unlimited. I have 4000 miles on it. I am having problems with brake noise. Every time i am reversing or braking on an incline or when i have my feet on brakes during stop and go traffic i hear a noise for few seconds from rear wheel. i almost paid $42000 and i feel like i bought a piece of junk. It is embarassing when i have passengers and they hear the noise. I took it to the dealer twice and they said they all do it. I am thinking to talk to an attorney. The jeep is still under warranty. Is anyone else having the same issue with brake noise?

Try a diff dealer first.
No noise should be heard. I once had a stone lodged between the brake disc and shroud cover, but it was more of as screech.

Have you tried turning off Hill Start Assist to see if that solves the problem?

funny how brakes work, friction.........maybe hit them with a few squirts of oil between the pads and the rotors that should quiet them down. Now if they are squeeling loud enough to scare pedestrians that might be an issue but if they are just making normal noises then chalk that up to the fact that wranglers are not insulated well from the outside sounds like many vehicles are.

If you paid $42k for a Wrangler, you got robbed.

Take the back wheels off and see if the pads are shifting back and forth as you turn the rotors by hand. I've seen other vehicles do this and making clunking noises. Also, if you can, remove the rear pads and see if they are damaged in a way that could be causing noise. And as far as what the dealer said that all of them do this. Find another dealer. He is full of it! Until you figure out what is causing this be very cautious.

Thats torque in the control arms being released. Perfectly normal. It is more of a groan than a squeek correct?

Here is what I mean by torque being stored in the control arms...this is a HIGHLY exaggerated example, but excellent for illustrating my point.

This is what I consider a squeek...I don't think this is the noise you hear because you are describing the groan noise that happens when you are stop/going



This noise is NOT normal.

This is the noise you SHOULD be hearing, and it is 110% normal....the noise happens from 25 to 30 seconds. Is this the noise you are hearing?



This noise IS normal.

My daughters 2011 Chrysler convertible does the same thing when backing out of the garage (downhill incline). She has taken it to the Chrysler/Jeep dealer several times and they can't get it fixed. Have heard other Chrysler vehicles do the same when backing on incline. Seems to be a problem they can't fix. Hoping my Jeep doesn't start doing it.

It's the factory pads and rotors. I replaced mine at 15K with a quality OE replacement and haven't had that issue anymore.

I don't see how noise like that is "normal". The stock brakes on my 10 Rubicon are totally quiet, except when hill start assist is releasing the rear brakes. If it was normal all JK's would do it and they don't. Unless from 10 to a 14 they changed the material of the stock pads I don't think it should "groan" as you described. Possibly one or more of the rotors "glazed" somehow or even warped, but without actually hearing it anything is a guess. I used Brake Kleen on other vehicles and it has helped with noise. Possibly when they were installed at the factory the contacts weren't properly lubed or there's a problem with the clips. I would address it again with your dealer, or try another dealer.

It is your control arm metal expanding and contracting from the torque built up inside them. It is normal and no, there is nothing you can do about it. All wranglers (or vehicles with solid axles) do this.

As stated...I can take both your Jeeps, and do this at will. My 2012 did it. My new 2014 does it, as does every single jeep on the lot. The problem CAN be exaggerated with a lift and stock control arms in the stock positions. You guys can chase this for the next 100 years, you will not get it to go away.

the cure will be coming in 2016 when they go IFS in the wrangler. Sure brakes pads on rotors squeak and sure solid axles are going to groan. I agree with the guy from NYC. fill your jeep with sound deading padding and it might help too.

I'm glad that YOU can make the brakes do that at will.. I can too but that slight squeak that was on the video is NOTHING like the sound that I was writing about. If the sound that was on the video was what I was hearing there would be no complaint but it is not even close. If I can figure out how to get a video of it on here I will post it. Makes the hair on the back of your neck stand up.

With all due respect, you wrote about your daughters chrysler, not your Wrangler, which you said is ok.

I was addressing the OPs question (which is a Wrangler specific noise,) so I am not quite sure what you are talking about or what your point is.

Just stating that other Chrysler products, Jeep being part of Chrysler, seem to have squealing brakes when going backwards on an incline, and that I'm glad that MY Jeep isn't doing that yet. Have not heard the loud squeal on all of them and say what you will but it is not normal. Just because you can do a thing doesn't always mean it is normal.

You need to understand that this is the internet, and what we are doing is typing words. It's very difficult to describe a noise in text. I posted two videos which CLEARLY illustrate the difference between what I interpret as squeaks and groans. The OP described a problem which is a NORMAL NOISE on a wrangler, and I posted a video (several) that illustrate this noise....the noise I said I can replicate on any Jeep, proving that it is perfectly normal. If this is NOT the noise you are hearing, then you have another problem...a problem that I am NOT talking about. The noise I am talking about, and posted videos of is CLEARLY not a squeal, a squeak, a rub, a thump, a pop, a bang, etc. It sounds like metal stressing. If this is NOT the noise you are hearing then it is NOT normal. If you hear a noise when releasing brakes under load (an incline, etc) then most likely it is the noise I am talking about, which is normal.

Replace the pads. I know it's new but ....
The brakes in my 07 are as quite as a mouse. Not sure which pads were in it when i bought it. they made noises unlike the better pads I have in now

My van on the other hand .... Well is embarrassing to drive anyways. The brakes only had to the strange looks I get

Every live axle vehicle I've ever owned has done this exact thing. It is completely normal. If you didn't want a vehicle that's built to do work and articulate its suspension, you should have done your research before spending 42,000 dollars.

That being said....it IS normal, you don't have anything to worry about, and I think you're a lot more conscious of it than any of your passengers. Ignore it. It's normal - machines make noise, and this noise is normal.

I highly suggest you take your jeep on a few light to medium trails before you get disheartened. You will fall in love with it once you're using it how it's meant to be used. Don't sweat the small stuff. This vehicle is not designed with NVH the way a normal vehicle is. You didn't buy a normal vehicle.

I'm not going to debate what type of noise might be considered normal. All I can tell you is that I have no brake noise with my 10 Rubicon, going up hill, down hill, or in any other driving situation except when the hill start assist releases. Other than that, I don't know. I also have no suspension noise. At this point, I'm not going to try and get noise out of it.

I refer to it as the Jeep mating call. Out crawling around in the rocks with the club is like being in a pod of whales in mating season.

This is the sound. They all do it to some extent however I haven't noticed my '14 doing it after the lift.

I am not used to a brand new vehicle making a load noise when you switch to reverse or drive or when I am backing up on an incline. The funny thing is 90% of them do and 10% don't according to the dealer. This makes me think that the problem is with Jeep and it can be fixable. I think if lots of new owners stand up on this issue they might do a recall. The dealer gave me some BS about how Gov’t mandated some type of rear wheel material few years back. This was my first Jeep and I love it but this noise really dissapoint me.
I will soon be posting a You Tube video of my 14' JKRU which makes a constant noise when I switch to reverse and backing up on an incline.
