Re: 2014 V6 Rattle?

I have the same issue. 2014 Limited. It started at 360 miles or so.
It comes from the left front side. Exactly what you guys are describing.
I brought it in once so far and the dealer gave it a quick look. I'll be bring it back for a closer look in the near future.
I will suggest to dealer what curtispwnsoil wrote...see above post concerning a Oil PCV hose contacting the firewall shield.
It is upsetting that I spent 40k and have this issue. Was the manufacturer really not aware of this issue when it was being tested?
Where do I register a complaint?

Re: 2014 V6 Rattle?

Just an update from my end:

Per the comments about a firewall rattle, I looked inside my engine bay behind my engine and I saw several lines that were very close to the firewall foil. So, assuming that when we press in the accelerator, the engine shakes/moves a bit and those lines hit the firewall, makes complete sense and also, after seeing the material in the back of the engine bay, looks like that would create the exact sound i'm hearing. Now, i will say that my sound has drastically decreased since i noticed the issue. Whether that being a line that has moved itself far enough away from the firewall so that it doesn't make contact (or as hard) or whether it's engine break-in or something else is anyone's guess.

I'll be at the dealer on Friday for a warranty replacement of another component and I'm having the techs look at the lines in the back of the engine and move any that are close and could be making contact. Will report back after my visit.

Re: 2014 V6 Rattle?

I am going to crack the hood and take a look this weekend. I am really hoping that's all it is. The location of the rattle seems to be right there too... sort of down and forward of me when I am driving. I wonder if some foam tape or something would dampen the sound more? Is it safe to affix stuff to the firewall? Yes, I am a novice when it comes to this sort of thing.

Re: 2014 V6 Rattle?

Anyone out there with new information to report? I'm being told by my dealer that this noise is "normal". Total BS!! Who can we write to at chrysler to make them fix this nonsense?? Has anyone had any success after contacting the corporate offices?

Re: 2014 V6 Rattle?

So I bring the truck to the dealer and they can't find anything that causes the rattle.
However, they did work on it for about 5 hours.
I did drive a brand new limited that was on the lot and NO NOISE.
Obviously there is an issue with this!
Next move is dealer is notching it up the ladder to some Jeep tech people and my next appointment is going to be with a specialized technician from Jeep.

I've also decided to take my truck to my local mechanic who has always done very well by me to see what he finds. I am beginning to think the rattle may be in the steering wheel column but sounding like it comes more from the left front. Noise does travel.
There is NO WAY I am going to live with this noise for 41K!

I'll keep you updated.

Re: 2014 V6 Rattle?

I had my dealer check mine out again this past Friday. Tech found three more locations of potential metallic rattle. They are as follows:

1. Engine cover, front left (when looking inside the engine bay from the front). There is no support under there to where tapping on the cover would reveal a metallic sound. Tech cut open some vacuum tubing and wrapped it around the corner of the engine cover to keep that from rattling against the top of the engine. Looks very nice I might add.

2. There's a silver line to the right of the engine cover that extends from the front of the engine bay into the firewall. The bracket at the front of the engine bay that held this in place had play in it to where the metallic pieces could have been rattling together. A quick wedge and jerk of a screwdriver behind that bracket tightened up the connection and limited movement.

3. A shield underneath the vehicle on the passenger side, straight in from the rear door was tight against the fuel tank underneath the vehicle. Tech bent this shield away from the fuel tank to alleviate any rattle from that area.

So, with that said...these have made an improvement in my noise. Can't say it's completely gone but it's much better. Still feels like I'm getting an "aluminum foil in the wind" sound from underneath the vehicle in the front end in that 10-30 mph range. At the moment, i'm a little more concerned about getting some other issues resolved like the transmission flash and noisy turn signal switch replaced as I do some more testing and have them take another look at a later date. The sound is definitely nowhere near as loud and grating as it was initially, prior to these fixes and heat shield bending they performed underneath the vehicle on my first trip.

Maybe you guys want to take a look at the two engine bay areas I described for potential issues on yours. I can't imagine that temporarily removing the engine cover as a test would hurt anything. I could take a picture of those areas as well if anyone needs.

Re: 2014 V6 Rattle?

Hey Vedled, thanks for the update!
I'll keep posting until it gets resolved.
I would be very interested in your pics.
Maybe you can post here?
Thanks!

Thank you for the info. Yes, please post some pics!!! I have been under the car doing my 'own tap testing' and bending and insulating. I too Have the engine cover rubbing very badly on mine...just didn't really know how to stop it b/c didn't want to put anything that could potentially melt there?

Re: 2014 V6 Rattle?

My engine cover was rubbing on another plastic part in the pass side front area. A test drive with the cover off showed no difference in the noise.

The aluminum foil cackling in the wind is a good way to describe it. At least in my car the noise is barely noticeable, I have to listen for it with the radio off. Are others experiencing about the same loudness level?

Re: 2014 V6 Rattle?

Yea, that's about the same loudness level that I'm at now. Mine was WAY worse from the start. I actually have to turn the radio/AC off and listen for it, which of course i do way too often hoping that it will magically stop one of these days. Luckily, this is one of those dealerships where the tech will talk to you directly and go over everything with you. I talked to him about the firewall deal thinking that something was vibrating against the firewall (which looks like an aluminum foil type material I might add) but he explained to me that they've gotten away from running lines in front of the firewall and that alot of the lines run the whole way around the front of the engine bay to get away from that exact issue.

I'll actually be back there in the morning for the transmission flash and switch replacement but I don't think i'm gonna mention anything about it on this trip unless he specifically asks. I always think that if I go in with a laundry list of things, they won't pay much attention to any of them.

Re: 2014 V6 Rattle?

Ask and you shall receive. Note my 4th grade level Microsoft Paint skills.

1. The circle is where he sliced open some small black vacuum tubing and wrapped it around the engine cover. There was a very tight gap between the edge of the cover and the intake tube. I doubt this actually had anything to do with the noise but at least nobody would realize that this mod isn't stock.

2. Bottom right arrow. That silver bracket on the front of the engine bay that holds the silver line in place...looks like it goes to the washer fluid or something. There was some play in that support. Thought was that maybe vibration there was transferring noise back to the firewall and echoing. Who knows, but a simple screwdriver behind that bracket and a little force bent the bracket out ever so slightly to tighten up the connection and eliminate any play there.

3. Top right arrow. As I was taking the picture and peeking around, I noticed that I have two relatively thick lines of some sort wrapped in foil-like insulation behind the engine. One of them is 3/8-1/4" away from the firewall. Sorry, i didn't take an actual picture. Sometime this weekend when my engine bay isn't hot, i'm going to see if I can pull that guy away from there at all.

Really hoping that #3 is the source of the sound i'm still hearing. Time will tell. The nice thing is that all 3 of these are simple fixes with no tools required. I would almost dismiss the engine cover as a possible issue at this point.
