Sonata NF (2006-10) :: Slight Knocking / Ticking Noise Coming Around Engine Area
It's a 2006 hyundai sonata LX.
Now Is it anything I should worry about? Car has 72000 on it. Always used synthetic Mobil 1 5w 30.
This is on a completely cold start up, 30 degrees outside. Only makes the noise until car warms up. Anything I can do to prevent this? Or is it not something to worry about? Should I just let the car warm up a little before I drive it?

Sonata NF (2006-10) :: Knocking Thumping Noise Coming From The Right Front
I replaced my struts and shocks a few weeks ago and i installed lowering springs H&R. Yesterday i started hearing this knocking thumping noise coming from the right front of the car me and my uncle took the wheel off today and looked around and everything was nice and tight we proceed to both push down on the right corner of the car to have it bounce up and down and we heard the same knocking sound coming from the right front area it sounds almost as if the strut blew out in the front right would the symptoms i described concur with the front strut being blown out, and on a side note the struts are only a few weeks old is this even possible since the struts are so new? I do have 20" rims on the car with low profile tires could i have hit a pothole hard enough to cause the strut to blow out? Iam planning on taking a trip to the dealer tomorrow and have them check it out.

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.
Sonata NF (2006-10) :: 2.4 Engine Loud Knocking Noise When It Is Cold
My 2009 Sonata 2.4l Sonata has been making a loud knocking noise when it is cold, but it will fade to almost nothing after it warms up. I tried to make a sound clip of the noise, but it was so distorted that I could not even make out the noise on the video.
For some strange reason the noise matches the skipping problem I have been complaining about since the beginning. Yea it's still there. It sounds like it is in the valve system, not the lower end. It leads me to believe it's coming from the valve clearance/ camshaft area.
Sonata NF (2006-10) :: Engine Shaking Violently In Compartment And Making A Terrible Knocking Noise
I have a 2010 Sonata V6 that I bought new. It has a little less than 50K on it. I tried to start it today and it made a terrible noise then died seconds later. I popped the hood and then started it again and the engine was shaking violently in the engine compartment and making a terrible knocking noise. I had driven it 12 hours earlier and it ran fine. I called a tow truck and had it taken to the dealer but if I know my dealer, since it is Sunday they probably wont get to it until Tuesday. Also, this car has had the signature V6 valve cover leak that has been fixed 3 times. I noticed it was leaking again about a month ago and I have just been checking the oil and adding it as it needs it. I dont think the engine ran out of oil because I checked it before the tow truck came and it was between low and full.

View 4 RepliesSonata NF (2006-10) :: Rear Suspension Clunk / Knocking Sound Coming
For the last year or so i have been annoyed severely by a clunking knocking sound from the rear (possibly passenger side) of the car. The noise occurs when there is torsion occurring or a sudden change of direction. I can go over a huge speed bump or pothole and not hear a thing yet the slightest change in direction or torsion will cause this extremely annoying heavy metal clunking knocking sound. I tightened every suspension system related screw in the rear of the car and the noise is still present.
The car is lowered on H&R springs (approx. 1.4 drop) so im wondering if maybe there is an additional stress that has been torturing the sway bar links for the last 3 years causing this noise. Or could it be the shocks (which are working properly)?
Sonata NF (2006-10) :: Rattling Noise Coming From Driver Side Of Engine Bay
Recently when I first start my car in the morning, there is a rattling noise, which sounds like it's coming from the driver's side of the engine bay, or possibly just under the drivers side door. It only lasts for a couple of minutes. It will increase I accelerate, and then decrease as soon as I lift off the gas. After a couple minutes, the rattling goes away, and everything is right in the world. Today I drove it around the block and parked while it was still rattling away. When I put it in park the rattling went away. I put it back in drive and it came back. Then as usual it finally went away whether in drive or park. I'm completely stumped on this one. It's an '08 2.4l GLS and has 138,000 miles.

I have a 2010 Hyundai Sonata GLS 2.4L. This problem started several weeks ago. When I turn on the ignition on the car, I hear a squeaking noise coming from the engine initially. Once the engine warms up, the squeaking sound lessen but does not go away. When I shift my automatic transmission to DRIVE, and press the accelerator, I hear squeaking noise coming from the engine again. I stopped my car and opened the hood. I could hear the squeaking noise coming from the front left of my car, if you are facing forward the front of the car. I do not know much about cars but I think it is coming from the fan belt/serpentine belt, or possibly alternator but I am really not sure.
Presently, the sound has gotten worse so I want to fix this as quickly as possible. I am second owner and the mileage on the car is 45,550.
Sonata NF (2006-10) :: Ticking Noise Coming From The Left Side Of Engine
I recently noticed a noise coming from the left side of the engine where the pulley's are. It sounds like a ticking noise coming from where the belt is. What the possible solution could be.
View 6 RepliesSonata NF (2006-10) :: Clanging Noise Coming From Engine And Battery Light Turned On
My 06 3.3 is having a problem with the pulleys. A few days ago something squealed, like a loose belt squeal. I put it off, then when I started it up this morning, I heard a clanging noise coming from the engine, and the battery light turned on. I checked everything out and saw that there is a pulley broken off which is rattling around the crankshaft pulley. I figured it was a pulley that had broken off, but all 7 pulleys in the car are present and accounted for. Incidentally, the serpentine belt is way loose, which would be why the car lost power and eventually died. Am I completely lost or did an 8th pulley magically appear in my engine.

I own a 07 Hyundai Sonata Limited with 31000 miles. It is 20 degrees today. When I start the car up there is this knocking sound from the engine. Once the car warms up the knocking sound only happens when the car is in drive or reverse. When the car is in park or neutral it is fairly quiet. The sounds is still there but not as loud as in drive or reverse. I have done the routine synthetic blend oil changes between 3500-4500 miles.

I didn't know my car was low on oil and the oil light never came on. The car has been working flawlessly till I got home and I heard a really weird knocking noise and it's a light knocking noise when the car is idling but when I press the gas pedal the noise becomes louder. The noise sounds like its internal it's coming from behind the engine near the exhaust manifold where the spark plugs are located. I have changed the spark plugs and drained and added new oil into the car but that still didn't fix the issue. The car has about 129,625 miles on it and is in mint condition buying a new engine would be pointless knowing that the value of the new engine is basically the value of buying another used car.

Sonata NF (2006-10) :: High Rpm Cold Start / Engine Is Knocking
Recently, our 2009 Sonata jumps to relatively high and not normal RPM when start cold (and I don't mean winter-cold; I mean first start in the morning). It jumps to around 2500 rpm for 3-4 seconds before it goes down to the normal 1200-1300 or so for a cold start.
Also, not sure if this is the normal Sonata engine sound, but when we push the accelerator it sounds like the engine is knocking, almost like a whistle of fuel flowing.
Sonata NF (2006-10) :: Knocking Sound From The Engine / Cutting Out After Idling
I was driving this morning after doing a brake job (nothing to do with the problem, just anger coming out) made it about 10 kms and noticed when i took my foot off the accelerator, the heater fan powered down a bit, and back up when I gave it gas...noticed a knocking sound from the engine...pulled into a gas station and put it in park. After a hard time idling, it cut out. I started it again and the idle was not good at all. kept cutting out. Got it going and made it home with the same sort of power issue. Tried to start it a couple times and same issue with the idle. Sputtering quite a bit and noticed quite a bit of exhaust coming out. When I backed it out of the garage, I noticed a small puddle of oil.

Sonata 2007 3.3L V6 ... I have nearly 70K on my Hyundai, and I am the original owner. Everything was fine until 24 hours ago until I got a knocking noise. I stopped, shut off the engine, and had it towed.
The mechanic says that based on the symptoms (knocking, some white smoke from exhaust) that it is powertrain warranty related, and I should be covered.
Sonata NF (2006-10) :: Suspension Noise - Creaking / Knocking Sound At The Left Rear
2006 Sonata 2.4 GLS. My car has done 60000 miles and has developed a creaking/knocking (metal on metal clunk) sound at the left rear. it is only noticeable at low speeds when accelerating and decelerating in stop start traffic.
It is not the shock as I have removed the shock and driven the car and the noise is still there, I have also looked at all the bushes and nothing is obvious. I have also checked tightness of all bolts/nuts.
Sonata I45 (YF - 2011+) :: Transmission - Valve Knocking Noise From Engine Zone
I have a 2011 Sonata GLS with 127k miles on it and I'm trying to diagnose a problem, possibly with transmission.
Since I bought the car at 115k miles I started hearing a noise from engine zone, which appears quite rarely. Noise resembles valve knocking, appears mostly at traffic lights and colder weather (evenings). I was trying to catch the sound by recording it while using emergency brake at D pos. but the sound disappeared right after releasing brake pedal.
Describing in a different way it sounds like a propeller touching something with its blades. The sound also appears at 1900rpm on any gear (mostly when slightly releasing gas pedal around 2k rpm).
While trying to understand/fix the issue I used:
- liqui moly valve cleaner and engine flush
- techtron injection cleaner
- replaced spark plugs
These operations had almost 0 effect on car behavior. The symptoms boil down to a torque converter. Transmission shifts fine, I was going to try transmission fluid change ( a full change by dealer), however it may do more harm, so I'm not sure yet.
Sonata I45 (LF 2015+) :: Knocking Noise From Engine Area During Acceleration On Freeway
I have a 2015 Sonata 2.0T and I have noticed knocking noise when driving. I experience it more when on the highway/freeway. I mainly experience it during acceleration. Not hard acceleration but when I want to overtake or when the road curves and coming out of the curve -I step in the gas a bit, I hear the knock.
