Hi, I’m new here.
My car’s been making a high-pitched sound, somewhere between a whine and a whistle, and I can’t pinpoint where it’s coming from. But it occurs only under these conditions (so far):
–I’ve been driving for at least a half hour
–I’m driving at low speeds
–The car is moving
And it goes away if I apply, or even tap on, the brake.
My first thought, of course, was the brakes, so I had them checked, and the pads are all good. The mechanic also used compressed air to clean out any debris. That was the first time I’d been to that mechanic, but he’s near where I work.
Since the noise continued, I’ve talked with him on the phone and in person a couple of times. (I took some video on my iPhone just to record the sound and the speed/RPM when it happens, and let him listen, although the video didn’t capture how loud the sound is.) He’s adamant it’s some kind of sheen on the brakes, or something to do with the weather (I’m in the Detroit area and it’s been cold and snowy). He says if it were a belt, the noise would be constant, even when the car was parked. Basically, he’s saying don’t worry about it.
Is there anything else it could be? Should I be concerned, or just wait and see if it gets worse? I hate to let it go if it’s indicative of a problem that could get worse - and more costly to repair!
It’s hard to figure out where it’s coming from, since it only makes the noise when I’m driving. Even if I roll down the window (brrr!) it doesn’t sound localized from where I’m sitting.
It’s got 132K miles. The previous owner (I’ve had it for a year now) had the timing belt changed at 99K miles, and also had regular service/maintenance done at the dealer.
Thank you for any advice.
