Noise Vibration and Harshness - let's hear them

My 2014 has 15.5k miles and over the winter it developed a vibrating noise near the driver side wind shield. It comes on around 2000 RPMs, sounds tinny fizzy and goes away. Over this weekend on a 240 mile round trip I hear a rattle somewhere in the engine bay. Like a jar with plastic marbles in it, consistent above 40 MPH and higher.

Anyone experience as well? I was going to schedule a visit with my dealer but this type of unplanned visits can be a real PITA in terms of time and energy.

AFAIK it is not the suspension, transmission or motor.

Something in the air filter box?

Of course after sitting outside all day in 70 degree weather the noises went away.

Sounds like you pinpointed it to the front of the vehicle, but I finally confirmed a weird noise in my wife's overland and it is the sunroof. I thought it was somewhere else, but it is the sunroof for sure. Might be worth pushing on the glass (if you even have a sunroof?) to rule it out. good luck I hate those ghostly noises in a vehicle

thanks but it is definitely in the front of the firewall. my friend's 2012 had the sunroof issue... a gasket had to be replaced to stop from leaking. part of me just think who cares, it's a lease, my first jeep, my first diesel, it's filthy, a DD, etc. just run it and return it when it's over.

Check under the jeep for contact of the heat shield on or very near the exhaust. That thing is so flimsy that driving fast , the wind will bend it and allow it to contact exhaust causing a vibration. Also pppppllllleeeeaaaassseee while under there tighten all the bolts holding whatever skid plates or fiber boards you have under there. I bet there all loose

Re: Noise Vibration and Harshness - let's hear them

it was the heat shield for the exhaust. the noise was finally consistent enough under repeatable conditions for me to bring it into the dealer. it's under warranty and fixed.

As Dom stated, check the fastening bolts on the protection plates. If you have the ORA package, you will probably find that the bolts holding the plates to the frame are NOT tight. I used Blue Loctite after the 2nd time they came loose!

I didn't get the ORA package. I wanted a diesel with a few options. Just got Luxury II pkg. I would have deleted the heavy panoramic roof if I could. In hindsight I wish I have the active cruise control for the long trips.

Re: Noise Vibration and Harshness - let's hear them

I mentioned this is a different thread, but I was getting a rattling from the engine bay near the passenger side, and it turned out that the plastic air intake for the AC was never bolted to the firewall and was just rattling around in the engine compartment. Luckily that intake area is bifurcated from the rest of the engine bay so no damage was done, but the dealer claims it came from the factory that way so could be an issue on other vehicles. They installed some new screws and problem solved.

Is the picture showing the bolt off by that pin looking thing protruding from the firewall?

Re: Noise Vibration and Harshness - let's hear them

Hi Peejym,

Yes, there are actually two bolts on either side of that vent intake shroud which come out of the firewall. The dealer told me that the factory simply failed to install the two nuts that hold the shroud on those bolts. They also suggested those nuts are usually just cheap plastic from the factory, and they did me a favor by using metal nuts instead when they fixed it...yipeeee. If you pop the hood and look into the upper left corner of the engine bay you should be able to tell easily whether those nuts are attached and that intake shroud is secured.
