Sonata NF (2006-10) :: Engine Cooling Fan Noise / Squeal
Feb 13, 2013
I notice a high pitch squeal when I turn off the car ignition and is synced with the slowing of the engine cooling fan. I don't notice any significant engine noise while the car is fully running in idle. Does this indicate that bearings are going bad in the electric engine fan assembly? If so, would the noise alone be justification for getting a warranty replacement by the dealer or would they need a total fan failure in order to get it replaced under warranty at no cost. If not, think its worthwhile to replace the fan module myself to avoid imminent failure?

I just did the brakes on all four wheels of my 06. I replaced the rotors and pads all the way around with Powerstop parts. I got them from RockAuto.COM as a complete set. The rotors were made in China generic looking things and the pads were Powerstop Evolution Ceramic Disc Brake pads.
Anyhow, I drove around to bed the brakes after getting them installed and now the passenger front tire as a small "rotational squeal" when you are lightly braking.
Oh, one more thing, I'll admit this up front. I did not put any grease on the back of the pads. This was mostly due to I wasn't sure exactly where or how much grease to use.

At 65k miles my wheels began to squeal off and on when NOT depressing the brake. Does not happen all the time. I had a mechanic look at it and tell me everything was ok other than worn brake pads and they should be replaced "soon". I assume the squeal was the brake pad warning noise. My question is with mostly highway driving and not actual problems stopping, grinding etc...How long do I have before I need to replace them? Now? 3k miles? 5k miles? How soon?

It was something rubbing on the inside do you believe this to still be the case? I bought the car new in 12/2009 and have 58237 miles now. Sonata SE V6

2006 Sonata V6. Front brakes only squeal when applying them while in reverse. Happens all the time......cold/warm start, cool/hot weather, dry/humid air. Squeal is extremely loud. I have searched and found similar but nothing exactly like this. Pads and rotors are fairly new and I have removed them and reinstalled and regreased twice. I am using ceramic pads and have never used them before. Is this common with them?

I have been hearing an intermittent high pitched squeal at 50 MPH and higher. Taking my foot off the gas or taking it out of gear doesn't change the noise. Hitting a bump or tapping the brakes makes it stop momentarily. It sounds like it is coming from the front driver side, though it's hard to tell.
I have about 33,000 miles on the car. My manual says that the brake pad replacement indicator should squeal when the brakes are applied.

While driving, I occasionally hear a hiss, which seems to be a/c related. but just recently, I've heard an extremely high-pitched squeal/whistle. So high-pitched I had to slow down, turn off the music, and tell my wife to stop talking :P to hear it. Brakes are not being pressed. Definitely not a brake problem. How do I know? I parked the car, with engine running, opened the hood, and looked for the sound. nothing. I turned off the car and was walking inside when i heard it whistling behind me, mockingly. it stopped shortly after.
I'm thinking it might be a/c related, or some kind of pressure hose. (a/c is working fine otherwise, as far as i know). It's not air leaking from the tire. I've heard it on and off for about a week and the tire pressure is fine.
I'm more mechanical with computers than cars, but i have a basic understanding. it seems to be coming from the driver side, under the dash/under the hood.

I have a 2007 Sonata and It recently lt began to blow hot air out of one side and freezing cold out the other side. Took it to the dealer and the technician said he didn't know what was wrong but recommended that the system be evacuated and refilled at a cost of 281.00. Actually, what he said is that the compressor is either overfilled or underfilled.

I'm working on 07sonata 2.4. The cooling fan is always on when key is on. I used to be a hyundai tech and remembered seeing something about the engine room fuse box and I have access to wiring diagrams. So in essence you go to connector jc01 pin 2 pink and connector je01 pin 25 pink. Cut the wires and connect them together bypassing the fusebox all together. But that didn't work this time. One thing I discovered is that if I touch my power probe to the heatsink of the fan control module I have battery voltage available. I first discovered this because I was removing said module and my 10mm touched it when it slipped a touch.
Is this 'hot' heatsink evidence of a shorted module? No codes in system. Ect tests good when hot and cold. A/c is not commanded on. Being that I used to be a tech for Hyundai I also know the engine fuse box can be touchy as well...

Was just on a trip (about 200 miles or so each way) and the AC worked just fine.
Car has sat for a few days unused.....when I used it to day, the AC blows warm...doesnt cool at all.
I hooked up a gauge to the low pressure side and the pressure reads very high (in the red zone of the gauge).....
Cant tell if the compressor is kicking on or not when the car is running...
Car is 600 miles out of warranty (of course).

2007 Sonata SE, 74,000 miles
Just took the car in for brake service (not the dealership) because of what I was convinced was a brake pad sensor warning sound - something I've heard with other cars I've had, and been correct about. However, the tech said the pads were fine.
The sound is a high pitched squeal, intermittent, coming from the passenger front wheel. It can be heard when coasting at moderate speed (30 mph or so), not so much when accelerating, and especially when turning left. It got worse today, with a low grinding sound at moderately slow braking speed that started after about two hours of start and stop driving (house hunting). The car has needed a couple re-alignments and will have to get checked for possible camber? adjustment (rear tires wore badly on outside edges, far less pronounced on front tires). Car has tendency to pull to the right.
Any thoughts on a main culprit here for the squealing-grinding noise or about the possible inter-relatedness of symptoms.

I bought my 2011 Sonata with 27k miles on it. After a while (few months) I noticed on occasion when turning I would get a screeching/squeal noise from the front tires. Only happened during certain turns (U turns I noticed where higher chance of happening).
I rotated the tires (Front to the rear, Rear to the front), and then there was a loud humming noise. I got it checked with the dealer and they confirmed tires were cupping (uneven treadwear right?) . So now its been 10,000 miles and the noise is the same. I just got an alignment done and there has been not much of a change.
So, other than getting new tires, should I get the tires balanced? Or just rotate them once more so that the rear return to the front again? Will I have to get another alignment done?

Few days ago I noticed the noise coming from the engine.
Went to dealership. They removed the oil pan and found metal shavings there .The car has 90,000 miles. They will put a new short block (will be covered by warranty ).
Since they basicaly will disassemble the whole engine, I thought to ask them to replace also drive belts, timing chain tensioner, not sure if the short block comes with the water pump , will ask them . W

I notice it now for awhile this whining noise coming from the engine. It sounds like bearing noise to me. The car is still under warranty till 12 Oct 13. So if needs a fix, it have to happen soon.

Yesterday I noticed a slight clacking noise coming from the engine, but it was only when I was just barely on the gas. It wasn't there at idle. Now today after an hour drive, it is loud, and at all rpm's. What could it be?

I did a search and what I saw all had to do with noise at startup.Mine is during cruising. I have a 2007 Sonata 4 cylinder with 112K miles. Within the last few months it began making a slight chattering noise when I accelerate and when cruising. It's worst around 55mph. When I let off, it almost goes away, but is loudest when I just am feathering the pedal to maintain speed.
If I put the pedal down a little more and accelerate, it is not loud, but still faintly there. At first I thought it was a tapping sound, but I've let some of my friends listen and its more like a clattering, metal rattling, or vibration perhaps. Its hard to describe. A week ago I had the check engine light come on with a "P0011 Hyundai - 'A' Camshaft Position Timing Over-Advanced Or System Performance Bank 1".
I changed the oil and took it into a local shop and they cleared the code/light and checked things out (the light hasn't reappeared). I had them take off the valve cover and make sure the top end was not making the noise. It seemed fine to them. They suggested I take it to the dealer for further diagnosis. I have not yet. It does not make noise during start up. If I have time I will upload a audio recording later. What may be making the noise? It seemed to get a little louder after the latest oil change, but that's probably me being more sensitive to the problem.

Ok, so I am not sure if i am having an AC issue or audio grounding issue...or both.
So here is the deal. I Have an aftermarket stereo. When I first got it, I Had to play around with the grounding points in order to eliminate engine whine noise. I got it perfect then lately it has become really really bad.
So I did some process of elimination and found this.
When I have the radio turned off, then whine is almost completely gone.
I just noticed that when I Have the AC on and radio on, the noise is there. In fact the AC is what makes the engine whine noise.
When I turn AC off, have radio on, no whine noise is coming through.
Now the kicker....I turned off the radio and accelerated while in park with AC on and radio off. I can hear a really loud {belt-like} noise coming from the engine. It occurs right at 2,500-3,000 RPM.
It definitely doesn't sound normal. When I drive normally I must have not noticed this noise because of the radio or it's too faint to hear to hear when outside of the garage.
Could it be some sort of tensioner on the AC belt tensioner? Not sure how this relates to my radio, but they go hand in hand and I would like to fix it.

I have a 2006 Sonata GL, 2.4L, manual transmission, with about 130K miles. It has recently developed a knocking noise. The noise sounds metallic.
Some data: timing chain, guides, tensioner are all new, the noise is not coming from there.
Compression tests on the 4 cylinders came back with 200, 200, 180, and 200 psi readings. Tests were performed 3 different times, same gauge, all numbers came back the same.
The noise comes on only under acceleration (gas is supplied), and even then it's not consistent. For example, accelerating at 2500 rpm will make the noise, but the noise will go away at, say, 3000 rpm, while accelerating. Then again, the same thing can happen at 3200 rpm: accelerating will cause the noise, but up to a point, beyond which the noise goes away.The noise is not present at idle. I can always make the noise heard, just not consistently at the same rpm range.
I ran the engine with one spark plug disconnected at a time: the noise goes away when the #3 cylinder spark is disconnected.
Opinions vary: wrist pin, piston slap, rod bearing, etc.
Any tests I could run to narrow the problem? It has been difficult to pinpoint where the noise is coming from with a stethoscope...
Oil changes have been very regular (3.5K), using Mobil 1. Nevertheless, it has been burning oil.

My 2012 V6 seems overly susceptible to the belts squealing (which leads to the AC not cooling until the belts dry) when I drive through a puddle.
I don't have charging or electrical problems or any symptoms of a too loose belt, although I suppose perhaps it is slightly loose? Or is this just a common problem because of a not big enough splash guard?
I'm not talking about driving through a monsoon flood with water up to the doorjams, I'm talking about even going 5 to 10 or 20 mph, through a dip in the road with a little standing water, and knowing water will splash up into the engine compartment, make my belts squeal, and half the time, make the AC stop until the belts dry.

2006 Sonata 2.4. A couple weeks back I posted about how my engine is making a slight ticking noise. It makes the noise consistently. I recorded a video of the noise. What it could be. Here's the video: [URL] ....
