Dear All,

I got my 2012 JGC a month ago. It has the off road adventure package I with the V6 engine. Everything runs fine. However, I can hear a whining noise during deceleration from 72 mph to 65 mph. In addition, this noise occurs during turns on the interstate at 60 mph. In all cases, the whine occurs when my foot is off the gas pedal. Does anyone have ideas what the cause is? Thanks

Re: New Member with a 2012 WK2 V6 engine.

Does yours happen just when you ease off the gas at highway speeds? Is it lower or higher in pitch? I've had the same sound but I guess I assumed it was normal...

Thanks for your reply. You are right, this whine occurs when I take my foot off the gas at highway speeds. It is a high pitch whine. I do not think it is the transfer case, because its whine is lower pitch. My theory is that it is the climate control system after the A/C was on.

Re: New Member with a 2012 WK2 V6 engine.

The sound that I have is a low whistle and it only lasts for a second or so...not sure if it's the same whine the OP reported. If so I'll be curious to find out what the cause is.

Re: New Member with a 2012 WK2 V6 engine.

Thanks for your reply. On my own, I did some tests. With the speed control off, there is no whine when my foot is off the gas at highway speeds. With the speed control on, but not set at a speed, the whine occurs when my foot is taken off the gas. Yes, the whine lasts a second or so.

The tough part of taking it to the dealer for issues like this is
  • Reproducing it
  • Getting the dealer to admit there is an issue
I've had another whistling sound I can clearly hear outside the Jeep and the last time I took it in and complained all I got was "no problem found". I'm hoping I can reproduce and point that one out at the next oil change...that one does not sound normal.

I'm mainly interested in finding out what the dealer has to say when the OP takes the GC in. My GC has made this sound since we have had it (with and without the cruise control enabled) and it isn't getting any worse or affecting the performance in any way.

OP is message board speak for Original Poster...

I had some more time with the Jeep today (it's the spouse's daily driver) and I noticed the whine at highway speed under very light gas pedal pressure. Also noticed that I could not hear it when I had the climate control system turned off.

I do have another whistling sound noticeable from outside the Jeep at idle when warm (need to get it to the dealer for an extended visit to track down). I don't think it's the same sound that I'm hearing at highway speed.
