Strange air/whistle sounds - 2013 Grand Cherokee

I bought my 2013 Grand Cherokee new (in the winter) and a couple of months later, in the spring, started noticing strange air/whistle sounds that are almost cartoonish in their quality. It's a sound that would represent something being filled quickly (if that makes sense) and the noise almost always starts from low to higher pitches. Kind of like a kid's paper whistle?? (This is the problem: accurately describing the noises.)

Source of the noise? No idea. Except it sounds like it's coming from the area below the steering wheel.

Noise doesn't occur when the car is fully moving, either. Just when the brake pedal is being used, just released OR right after car gets put in gear. Because the brake pedal is depressed on start-up, the noise will sometimes occur after start-up, but it also happens if I'm sitting in Park for a minute then depressing the brake, and sometimes at a stop light. There is zero predictability as to when it does occur, but it does occur primarily in the warm months.

My service advisor has heard this several times over, but without them being able to pinpoint or replicate the sound, they are not about to get in and diagnose the problem.

Thoughts? Thanks, everyone.

Hmmm - I'm not experiencing that kind of sound at all. Have you had the brake-booster recall performed yet?

It sounds like either a vacuum leak or the more likely the booster's vacuum check valve. There have been several reports of noisy valves early on, I'm a little surprised the dealer didn't just replace it. Perhaps try searching for "check valve" or "booster noise" and something similar may show up.

I also have a 2013 WK2 & I've noticed the same whistling sound from time to time. But because it's so intermittent, I haven't discussed it with my dealer when I've brought it in for routine service. I'll be interested to see if you find anything out. Good luck.

klueders,

I'm sorry to learn of your whistle concern.

Notifying your Jeep dealer is essential when any inconsistencies are noticed. In regards to intermittent concerns, dealer duplication is very important in order to accurately pinpoint the root and address.

It seems as though you have noticed a number of circumstances in which the noise is heard. If you are able to recognize a trend or tendencies when is noise is heard, this will help replicate the issue.

Have you had an opportunity to speak with the Service Manager?
