Has anybody else had a intermitent squeeling noise that seems to be coming from the wheels or brakes while driving. It disapears when I get on the brakes sometimes turning left or right will also make it go away for the time your turning.
 
Sounds like your pad wear sensors are beginning to touch the rotors. About 25-35k miles on your Santa Fe?
 
shouldn't pad wear sensors only engage when your on the brakes and and not when your off the brakes or accelerating??
 
My 2002 4wd Santa Fe has this problem too. It is not always reproducible and never will do it when the dealer checks it. The noise will always go away if you touch the brakes. Then sometimes it will come right back and other times go away for a while. The car has 34K miles and has been doing this for at least 6K miles. They supposedly checked the brakes at the 30K service. Any suggestions appreciated. Thanks, Al

I know of a humming noise (not as high a pitch as a squeal). If you've ever heard a Ford idle actuator making a loud humming, it sounds almost like that. I think I've been able to duplicate it only up to 20mph or so. It always goes away when the brakes are depressed. A call to Hyundai led them to tell me that this noise was coming from the front brakes and to apply anti-seize to the caliper slides and contact areas and to the pad backing plates. I've duplicated this condition on two vehicles and neither has returned. One customer called back to say that the condition had been corrected. Both vehicles on which this occurred had paint on the backing plates that was flaking off and rust underneath where the caliper pistons contact. I thought it might be possible that the flaking paint/rust might set up the right conditions for a vibration.

Thanks, that makes sense. The noise I have is better described as a humming noise. I will share this with the dealer when it goes back in.

Mine is more of a squealing sound, kind of like the sound you hear when you apply metal to metal at high speeds. I had an appointment with the dealer today, it squealed most of the way but as I expected, stopped 10 miles from the dealer. They took it for an extensive test drive but couldn't duplicate the noise. The last service they had to do something to the front right calliper cause it was hard to turn but this noise seems to be coming from the rear wheels.
 
I had the same problem and the same difficulty pinpointing the cause. Finally the dealer replaced my power steering pump and everything was ok for about 6 months. It recently began again and today I was told that the pump damange has returned to the new pump due to foreign materials in the lines. They are now replacing the pump and all of the lines...based on advice from Hyundai and still under warranty...let's hope it stays fixed this time.
 
was it a squealing sound like metal on metal, ours sounds like it's coming from the rear wheels, can't figure out which side but I'm thinking the right side. While the car is cold there's no sound but as soon has a few tens of kilometres have been put on the sounds shows up. It's very annoying. My brother in law thinks it may be the bearings, I don't know I'm not a mechanic.
 
Very interesting to see this post as my car has been squeeling for over a week, but if I apply the brake it stops. So I took it in to my mechanic & he asked if the car has not been parked in the garage? True, it ws outside due to storage for a friend in our garage. So he tells me moisture builds up & that is the aqueel. So night before it got it home back, & now no squeel.
 
So, according to your mechanic Santa Fe's need to be parked in garages?? Hmmm I don't remember seeing that mentioned in the manual. I got the brake pads replaced yesterday and so far no squealing, yet but the true test will be this week-end. I'll post on Monday to let you know if the car squealed during our drive up to Bissett Creek.

probably squealing due to being owned by the great WHINE
 
Surprising to me & my DH that since it is back in the garage the squeel is gone. Almost 27K on the odometer too. No wallet game here either.
 
Looks like you where right on this one, haven't had a sound since I got the pads replaced, went up north for the week-end to do some atv riding and I didn't get a peep out of them :o)
