Hi All,

Keep getting a whistling noise on my 2015 KL Trailhawk Cherokee it happens in gear, neutral, park etc, doesnt go away while driving either, it started at about 200KMs I now have 500KMs on the clock I have no idea what it could be...any ideas?

Here is a link to a video of the noise...it will ask you to sign up but just hit the little x and it will show the video

Why haven't you taken it to the dealer?

We have it as well. But ours seems to go away in Neutral or Park. Going to show the dealer with the next Oil change in April

Took my car into the service dept today, they advised it is the rear diff solenoid that controls the 4WD mechanism is buzzing. They are waiting on Jeep head office or something to determine what to do. Sounds like its going in to have some repairs done at under 600KMs on the clock.

I have the same whistle. It only happens to my Cherokee in the morning when pulling out of the garage on a cold start. A whistling sound coming from near the rear axle. Then it goes away. I've had that problem for at least a few months. I took it to the dealer a few months ago when it started to occur and left it there so they could keep it over night to hear it on a cold start in the morning. They kept the vehicle there in their parking lot for three days, did not look at it, and finally I went there and they came out to the lot with me. I started it, put it in reverse and could hear the noise faintly, but they could not hear it. So I took it home. Been living with the problem ever since then. Eventually it probably will get worse and then they will hear the noise. Every time I hear that in the morning I figure that eventually something is going to go wrong and fail. Even if I let them know about what others have had fixed on this forum, they won't do anything until it is a real problem. I even brought a video recording to the dealer showing the problem and they would not listen to it. I posted on the forum previously about this problem. I've never had a vehicle before this one that whistles. Oh well...

I have the same whistle on my 2015 TH as in the video.

I had it into the shop once already and they said they noticed the same sound on three other vehicles on the lot so "that's just the way they are".
I'll be taking it back in this week to talk with the service manager and showing him this thread.

Thank you for posting your results! I'll provide feedback on how mine turns out.

I also have this sound, not quite that loud yet. Its the sound of a solenoid being activated/bad solenoid. Its not too loud, at first i thought it was the fuel pump. Wonder what it does. I hate the thought of having them tear the diff and axels apart with only 400 miles on it.

Mine is three weeks old and has had the whistle from day one. I hear it every time I stop at the coffee shop's drive-thru (I stop there often !), with my window down and the building's brick wall alongside enhancing the noise. I've also heard it while standing next to the idling Jeep. Park, neutral, drive, no difference. For now it's intriguing and I can live with it. Dogs in the neighborhood might hate me though...haha.

2015 TH with the whistle off the lot. It's noticeable but I never assumed it signified anything was wrong.

My 2015 TH also has the whistle. Post #10 in this thread describes how one person got theirs fixed:

Adding plastic washers sounds like something easy to try and apparently some dealer in Germany decided to tinker around and it worked. Not sure anybody here in North America would be so bold. In a way, doing this is a modification on a vehicule under warranty and should be sanctionned by FCA. Problem here is that FCA seems to not give a crap. How much would it cost to add a plastic/nylon washer ?

Mine has this whistle too and it is an irritant..

Here is what fixed my whistle they had the car in the shop for 2 days


Did the noise ever come back after the repair? I think some people had replacements and they ended up making the same noise after a few weeks.
