metallic screech when I back out in morning while turning wheel, NOT BRAKES

[sgaudin]

Hi everyone: I need help identifying a problem I've had with my 2010 Genesis 3.8. I have 10,000 miles now and kept hoping it would go away but it hasn't. I'd like to have some info BEFORE I bring it in for service as the local service dept. was not helpful at all with my steering wheel memory [or lack thereof!] issue.

Every morning when I back out of the driveway, there is a loud metallic screech from the car. It also sometimes happens at other times of the day. I researched here and thought it was the "brakes develop rust overnight in wet conditions" issue, but then I started backing up this week WITHOUT USING THE BRAKES and the screech is still there. Here's the kicker. I have to turn the steering wheel to back down our driveway as it is NOT a straight shot. It happens when I turn the steering wheel.

Any ideas what this could be? I backed in today so I could pull out straight tomorrow morning [while turning steering wheel] to see if it also happens when pulling forward but I don't expect it will.

Thanks!

I have something that is not identical but could possibly be related. My driveway's curb cut is quite high and sharp (a big bump). When I back out with the wheel turned hard to the left I feel a crunching or grinding sensation from the front end as the wheel travels down the cut. This is not a noise, but a vibration I can feel through the steering wheel: it does not happen when I back out straight, with the wheel straight ahead. I haven't mentioned this to service yet but plan to next time the car is in for maintenance.

I have the exact same problem. I just bought the 4.6 last month and I have heard a loud screech couple of times when I am backing out from my garage (not tire noise). I also have to turn the wheel when i am backing out and have heard the screech only when reversing. Does not happen consistently tho...

My driveway is the same and I get that grinding feeling. Also the front wheels feel like the wobble off the driveway. very weird sensation.

Does the sound happen when car has been driven and warmed up? If the sound is only after car has cooled down like in the mornings then it can be the disk pads. My BMW has that kind of sound when first backing out on cold mornings and it is the brake pads. You don't have to apply the brakes for this noise to occur when a car is cold.

I agree, especially if it only happens in reverse and only after sitting for hours.
If the OP experiences silence tomorrow morning that should confirm it.
Btw, has happened to me twice so far this fall. No big deal once you know what it is.

I had the same thing happen to me on two different occasions and it turned out to be a pebble sized stone that was caught in between the metal protector plate that also cools the brakes and the rotor. Once the pebble was removed the sound was gone.

This unfortunately can happen more than you or I want it to. A certain amount of high-pitched brake noise is considered "normal" these days because of the harder semi-metallic disc brake pads that are used on cars now. In my experience, the smaller cars like Honda and Toyota seem to have the most trouble with this. Squeals heard the first few stops in the morning when the brakes are cold and somewhat damp from dew, and squeals that are heard the last few feet while coming to a stop are usually nothing to worry about.

Semi-metallic brakes are made of bits of metal shavings in place of the asbestos material that has been banned by the U.S. government. These semi-metallic brakes have great stopping power and have a long wear life, but can cause a high-pitched squeal that drives car owners crazy and frustrates mechanics who can't get it to go away to please their customers.

I have the same sound virtually every morning. Just in reverse. Applying brake does not make it stop. (2011 3.8)

Small rocks seem to get caught in the brakes of the Genesis, and that's where the screech is coming from. I'd recommend pulling the wheel off and poking around the caliper to see if you have any stones lodges in there. One telltale sign would be a scored groove in the brake disk where the pebble or stone is wearing into the disc.

update from this morning's test:

*it only happens in reverse, not when driving forward

*it only happens when I turn the steering wheel; not when reversing straight

*I am not touching the brakes in any way; if it had anything to do with the brakes at all, why does it only happen when steering wheel being turned?

*just ran out to driveway to test again after driving all morning and no sound. So, it happens first thing every morning but only every once in a while during the day after the car has been driven.

any more ideas? I'm going to print this all up and bring with me to service guy. Thanks for your help.

I don't think this is the problem but I remember having a similar "sounding" issue with my first generation Sonata back in 92. I think its called the CV Boot. Its located on the hinge where the wheel pivots. It was loose and it made a grating sound whenever the wheel was turned and vehicle was in motion. I don't know if the newer cars has the boot now. I have to hear the sound.

Another thing I'm thinking it might be is that there might be a metal ball bearing that isn't well lubricated when it has not been driven for awhile. When a vehicle is turning, I think more pressure is applied to the bearing causing the screeching noise. Once it is driven for awhile the bearing gets evenly lubricated again and lasts awhile until the oil settles again. I guess kind of like the engine. The engine oil will eventually seep to the bottom but that's why we let the vehicle "warm up" to get the oil well spread out as well as actually warming up the engine before driving. Just a thought.

I have experienced this exact same thing on several cars. Pebbles can definitely do this. Alos, maybe have the dealer check the parking brake for possible adjustment.

I have the same sound occuring on my 3 week old 2011 3.8. Didn't happen yesterday when backing out of garage, but after work it did it. At that time I was testing for it so put car into R without foot on brake. SQUEEK.

Not a pebble.

My car has the electronic parking brake (never used yet) and the "hold" feature (not use yet either). Wonder if others who are having this problem have these features, too?

Will post more as I test mine, too.

Anyone taken this issue into their dealer for service? What's the verdict? It's annoying my neighbors early in the morning!

 

[ASHDUMP]

The only think I can think of is this: In order to start the car you need to push the brake in. I know that in the morning when I start my car I pull out forward, but I can hear the breaks clink when I make my first turn out of the parking spot.

You brake might be trying to release itself but doesn't fully. Thats the only thing I can think of.

 

[CenTexan]

Mine still does it, but is now less frequent (hopefully I'm not just getting used to it). Haven't had time to really investigate.

 

[firstov]

I've noticed the same thing with my car as well. It only happens when the parking brake is engaged overnight. If no parking brake was engaged - there is no screeching (it's actually sounds more like squealing)

 

[binarypulsar]

Since I bought the Genesis 4.6 in May 2010, the squealing in reverse problem has existed. Whenever I back out of the garage or out of a parking spot I hear the squeal.

I brought the car into the service department many times for this problem and service tried many things under warranty (adjusted calipers, cleaned calipers, replaced calipers, replaced rotors). None of them fixed the problem.

About four weeks ago the service rep called Hyundai Corporate about the problem and was told to replace the emergency brake shoes.

I brought the car in and had them replaced under warranty.

I have not heard any squealing while in reverse since this was done.

Hopefully it stays that way.

Guys,

I was driving today and all of a sudden this screeching noise from my front wheel started. It was pretty loud. Almost sounded like my wheels were falling off?

so i stopped and looked and everything looked okay. So i get back in and start driving and it was still there for a few minutes and then it was gone.

so my question is how often do you get rocks stuck in your wheels that makes this sort of noise? i know one of you faced this before. How long did it last? How loud was it ?

I am just trying to figure out if i should take it to the dearlership or just ignore it, if it was just a stone.


thanks
