Whistling noise at high speeds.

[m3mtl]

When I drive on the highway in 5th gear above 100 km I can hear a whistling noise coming from the dash. It occurs when I push lightly on the accelerator. After I go above 110 km it stops. Its not the tires. It goes away when I let go of the gas. The engine is not making any funny sounds or anything. Does anyone know why I hear this whistling sound in last gear between 100 to 110 km. Thanks for the help.

you have a aftermarket intake or anything on your car???

Could be a piece of ice stuck to the outside of your car, and the way the air hits it at a highspeed you'll hear the resistance whistle.

Windows are rolled up, mouth is closed, and no boogers in your nose? Seriously though, are you sure it's coming from your dash? Any chance it's the speakers (i.e., radio interference)?

was the windshield replaced with an aftermarket one?

[m3mtl]

No. The noise is puzzling me as well. Its been really cold lately in montreal. Just will live with it I guess.

Goto the car wash, and see if it still happends. Quiet possible its coming from an area of weather seal like window,door or something.

i experience the same thing and when i took the car to the dealership they said that they had no idea what it was and that because so couldnt do anything about it.

There is another thread on this somewhere but I can't seem to find it.

The noise you are describing sounds like it would have to be coming from the engine, rather than the dash if it only happens when accelerating. I get the same noise in the winter and summer. Is it almost like a faint squeal/whistle? Really difficult to describe. For me it happens at any speed, but goes away after driving for a while.

I don't recall if anyone was able to actually solve the problem, but I think quite a few members had experienced the same thing. So I don't think it's too much to worry about unless it starts to get pretty loud.

Hope that's somewhat reassuring!

EDIT: One more possibility, a while back I was getting a weird high pitch ticking/whistling sound when reaching 120kph only. The sound went away when letting off the gas at that speed as the car slowed down. Turns out my splash shield and mud flaps were falling off/chewed up causing the wind to pass through them and create that extremely loud and annoying noise. Maybe that's something to look into as well? Just a suggestion! :)

Any chance you both have a bug deflector?

[m3mtl]

i have a hood deflector.

[Donutz]

Take the bug deflector off and see if you still get the whistle.

[zakman]

i have a bug deflector on rite now but i have had the noise with and without the deflector. i have kinda just given up on trying to figure it out and have also realized that well my gas millage is good and nothing else is going wrong so if its not broken well then i guess dont fix it. i just turn up the stereo

this is exactly what i experience

I actually noticed something similar the past few days. I would best describe it as a high-pitched whine that seems to vary depending on my throttle input. If I back off the throttle at highway speeds it diminishes. It sounds like electrical interference, but still occurs with the radio off. I've grounded my throttle body seperately and it seemed to make no difference. I'd be curious if anyone has found a solution.
