Weird whistle-like sound coming from front of car...just curious.
 

I honestly :search: -ed for a thread on this, but after a while I had no idea what to put in the search terms for this question.

My car is just about 3 years old, close to 50k miles. Occasionally I would hear this random whistle-like noise coming from the front of the car lasting for about one long second. At first it was pretty rare I would hear it, so I shrugged it off. However recently the whistle has been more and more frequent. I made a short trip into town today and I must have heard this whistle noise about 5 times. Anybody experiencing this whistle-like noise? It almost sounds like a child's toy. Anyway, thanks for y'alls help.

Do you have a cold air intake?

this

or a new throttle body that isnt on correctly. i had a whistle sound from my car b/c the throttle body wasnt tightened enough

what about a catch can with a drain tube?

Do you have a turbo?

Seriously though, wasnt there something weird with the side mirrors or something that caused an occasional whistling sound

yes my mirrors whistle every now and then lmao

Yea there is some hamonic noise from the mirrors (has been discussed in the past), but I assumed the OP was hearing it from the engine.

hey thanks for the responses... definitely not from the mirrors, lol. Like I said it is a difficult sound to describe. In response to a few of you, my car is 100% factory outside of an aftermarket axle back exhaust, so it couldn't be a cold air intake or turbo. it sounds like if you were to hum or whistle a low pitch then go to a high pitch.

The only whistling I hear is from my side mirrors. Known issue. If not that, then I don't know.

Did they ever come up with a fix for the mirror noise?? Mine has done it bad from day 1

Mine makes a whistling noise (under the hood) after I cut it off. Last for about 10 to 15 seconds. Has always done it.

I also have a whistling sound that is very ... sporadic sounding. It is kinda quiet and squeaky when idle. At first i thought it was a slipping belt, but opened the hood and listened, but didn't hear anything. I have the K&N CAI, but all the hoses are airtight and nothing loose. Should it still be making that noise?

A lot of times the vacuum created by the CAI will cause that whistle.


OP-- man, I dunno. You've got me stumped...
