Sonata NF (2006-10) :: Engine Shaking Violently In Compartment And Making A Terrible Knocking Noise
Jul 12, 2015
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.

My 2007 3.3 Sonata has begun acting up at a cold start up. The motor shakes violently and I have to cut it off and try again. It normally smooths out. This has happened intermittently two or three times in the past three years but happened twice today.
I am out of town at the moment and my wife has the car. She is worried about driving. I am thinking it is some type of sensor etc. If I knew what it was I could have her take it in and I could monitor the repair process.

Any way, my 2007 Sonata with 57,000 miles just developed a whining noise on the right side of the engine compartment. It sounds like it is concurrent with RPM and I thought it might be the alternator, the drive belt or some pulley. I have even seen on the general internet that some others had a bad oil filter. To me, the noise seems to be coming from the alternator area. It is a relatively high pitched noise that almost sounds like an electric motor. Would love to get it fixed. I am nearing the 60,000 max on replacement from certain items and do not know if the alternator is covered.

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 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 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.

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?

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] ....

My 2.4L engine is making a clanking noise while running. When I checked the oil level today, it was low by about 1.5 quarts. There's no check engine light.
Car has 74K miles now. I purchased the car two years ago with 35K miles. I have always performed regular maintenance myself. The car had its oil control valve replaced at 55K miles.

Recently my engine started making a rattling noise. It does not matter if the engine is warm or cold. In either condition it produces the same noise. The noise can be best heard at the back of the engine. My car is a Sonata 2.4 GLS from 2006 and has roughly 110000km on the odometer.

Tomorrow I'm dropping the car off to the dealer in hopes that they can find it.

My 2008 ex Honda Civic. Engine: (140hp 1.8-Liter SOHC 16-Valve i-VTEC 4-Cylinder 5-Speed Automatic with Grade Logic Control).
In the mornings, when I start it, it shakes & makes a hollow shaking noise in the engine compartment. This noise is normally more noticeable after having it parked overnight or not driving it for a few hours. The shaking noise is more pronounced after being parked overnight, starting it, & also putting it in reverse. After driving it for 30min, the noise & shaking stops.

Within the last few weeks my Sienna has begun making a terrible noise and shudder when I accelerate. It seems like it is worse on the front passenger side. When slowly accelerating from a stop it makes a hollow pitched metal scraping sound that increases frequency with speed (up to 25-30mph) and at higher speeds just the shudder, no sound. Initially this was intermittent but now it is an all the time thing.
The sound and shudder only happens when accelerating, regardless of speed. When you are at cruising speed on the highway there's no shudder as long as you are at constant speed and at any time if you take your foot off of the gas pedal the noise and shudder stop. Because of the link to acceleration I don't think its a wheel bearing.

I have an 08 Sonata Limited. About a 3 months ago, a noise began appearing on the driver side, sounding like it was coming from the engine compartment, and it has become steadily worse.
Today, I am learned how to replicate the sound, but I cannot locate where it is coming from. Here is the scenario:
The sound is a squeaking, like 2 pieces of styrofoam being rubbed together. The sound comes and goes. The engine must be in Drive or Reverse, and under load, meaning the driver side tire must be on the ground. If I jack the car up so that the drivers side wheel is off the ground, and put it in D and let the tire turn freely the noise does not occur. The car does not need to be moving for the sound to occur; in fact, it sounds worse when the car is at rest.
Today, I jacked the car up and took off the drivers side front tire to see if I could identify the source of the noise. Later, I put the tire back on the hub, and without lowering the car, started to tighten the lug nuts. When, I tightened the nuts with a wrench, I began to slightly turn the axle and shift the location of the engine and lift it, and I heard the squeak! Obviously, the car was turned off, so I was able to repeatedly shake the wrench and slightly turn the wheel, which shook the engine, and repeat the squeak each time. I lowered the car and jacked up the passenger front side of the car and did the same thing; I was unable to get the sound to occur.
I could now identify the direction of the sound, and it was coming from under the air filter chamber. I tried removing the air filter box, but it is held in place by a rubber plug and the air intake tube. Unable to remove the box, I could not see exactly where the noise was coming from.
Is there a motor mount under the air intake box, or is there another part that may shift over time and begin to make this noise? My best guess is that when the car is in Drive and under load, the engine vibrations are causing something to make a squeaking sound.

2008 Sonata Limited.
When I accelerate from a stop there is a metallic rattling in the engine compartment. My best guess is that it is near the middle and near the firewall. Can't see much under the hood in this area.
The rattling stops after about 60km/h or so and does not happen at all during cruising otherwise.

Yesterday, while at the store. I started my 2004 prius and the engine was making some crazy knocking noises. I went to auto zone and pulled the codes. It said random cylinder misfire and misfire on cylinders 2,3, and 4.

2000 Pontiac Grand AM SE 2.4L DOHC 129,000 estimated miles. After arriving home from the highway, I took notice of a noise coming the engine. Popped the hood just to hear the knocking noise. I had a mechanic from a dealership listen to it. His said it was a lifter or two. Doubtful of what he said, I got a second opinion and this mechanic said it was a rod. So, my question is this, can the rods be replaced without removing the engine?

I purchased a brand new 2014 Sonata Limited 2 months ago and took it to the local dealer last night for two issues.
The first issue was small rust spots on the sillplate and the second is a very slight clicking noise I hear from the engine compartment now when I turn the temperature dial.
The dealer just called and said that the clicking is "normal". The car didn't do it for the first two months.

Recently I started to hear engine pinging/knocking-like noise when the hybrid battery level becomes low like two bars and the car starts a charge cycle. I also hear it occasionally when I accelerate on uphill. Is this normal or should I take it to a mechanic?

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 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 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.
