I have wheel noise, best described as a whistling or higher pitched
grinding noise, that my 2007 Sonata makes. The noise occurs almost
exclusively when driving straight - when I make turns or apply the
brakes the noise goes away.

I took it into the dealer (6/12/08), they said they checked
everything, even test drove the car and didn't hear the noise (it does
sometimes take a bit of time while driving for the noise to kick in,
but the noise is there EVERYTIME I drive).

Again, the dealer says there is nothing wrong with brakes, tires,
suspension, etc. So I am not worried about safety, but the noise is
annoying and embarrassing. The dealer thinks it is the brakes getting
too hot and then making the noise. I honestly do not drive more than
28 miles round trip to work and back, so I cannot believe the brakes
get too hot.

Anyone have any ideas what it can be or what I can do? Is my dealer
full of you know what?

Thanks in advance.

Here's my guess:

The brake pads are seizing in the calipers.
This causes the brakes to stay applies slightly.
In turn, the rotors heat up, and the rubbing makes the noise you hear.


I've seen this several times, mostly on cars that are driven 500 miles a
month or less. It tends to happen after there's a small amount of rust
buildup on the backing plates, creating just enough friction to cause them
to stick in the caliper bracket.


Check with the dealer and see if you can make an appointment for them to
look at it right when you arrive after driving the car for the appropriate
distance. Have them ride/drive with you if necessary for them to duplicate
the noise.

I can't hear your noise, of course. But a wheel bearing can make a noise
which goes away upon the load of braking or turning. .02$

This describes the wheel noise exactly that I am experiencing on my 08
Sonata. I will be bringing it to the dealer tomorrow morning...if I
find anything out I will reply again... :!:
