There's three noises I can't identify, that I might have a dealer check out:

1) High pitched whine from front of car/motor. Its quiet enough that you don't really hear it with the radio off, and I think its coming from the engine compartment. It follows engine RPM in pitch, and sounds almost exactly like a ground loop, but I can't localize the sound with my ears to the stereo, really does sound like its coming from the bay. Should I be concerned?

2) Rattle at speed either in lower drivers door panel or front fender area, pretty annoying sound. Only hear it at speed, but its hard to pinpoint

3) Passenger seatbelt guide loud rattle/buzz over bumps. This one is the worst of them, I can't see how to fix it.


Anyone have similar unwanted noises in their car and have them fixed?

 

I'm taking my GT in tomorrow because the brakes make a weird noise when coming to a stop under firm braking.

 

1 is something I have and I'm pretty sure it's just the air intake. There's a sound tube that connects up in the air tube close to the engine that runs to the cabin, and I think that's why we actually hear it. At least that what I think it is. I personally thought it sounded faintly like a supercharger, haha.

2) Rattle might be a random loose or missing bolt like one guy had. I mean it happened once and it sounds similar to what he had. He had to take the door panel off though to see it.

3) This one I really don't know about.
