Accent MC (2006-11) :: Knocking Noise Under The Car For A While
Dec 8, 2010
Ok, I've been hearing the strangest noise under my car for awhile now. It sounds for all the world like a drum stick is hanging by a rope, swinging back and forth, and hitting against something solid. It makes 3-4 loud taps and the vibration can be felt through the gas pedal/floorboard. It ONLY happens when pulling out while turning left or right and going over a rough entrance like a rain gutter that bounces the car pretty decent. So whatever it is doesn't start swinging under normal driving. For the life of me I can't imagine what could be that heavy to make noise like that and not be causing any other problems.

so with the weather turning cooler i have noticed a new noise. i am at 34,000 miles and run synthetic oil ever 4-5k miles.
I hear a rattling/knocking noise when you start engine, not right away, but like after 15 seconds and it lasts about 30 seconds then seems to go away and is quiet again.
Almost sounds like a lifter is tapping due to not getting oil.
I changed the accessory belts a while ago and it did not first make this noise right after but maybe a few days after which coincided going from 80 degree weather down to 40 degree weather.
Could it be an accessory belt being too tight? If so, why wouldn't it make it on startup? I can see it going away as rubber expands as the warms but I would expect it to make the noise from starting till then. Not 15 seconds into running.

My car is accent 1.4 A/T 2012, and lately I've been hearing this metallic knocking sounds underneath my car. it happens every time after i drove my car for a longer distance and even on a shorter distance with no minimum running speed, you can hear the metallic knocking sounds whether the engine is on or off. Sometimes it is too loud you don't have to go out from the car you just have to roll the window down to hear it.
I've brought this already to my dealer and told me it was normal but I don't want to accept their answer so i refer it to another hyundai dealer. the second dealer made an adjustments on the muffler and catalytic something and even upgraded the CEU but to no avail and even adjusted my steering preload. BUT I'm still hearing it!! What to do.

Car ran dangerously low on oil (oil leak that we didn't know was present) and started knocking quite badly.
I pulled the valve cover to check the lifters and everything seemed fine up top. I tried to drop the oil pan but I couldn't get it to separate from the block.
If I can remove the oil pan are the main and rod bearings that hard to change or do they require special tools?

I have yet another issue with my Hyundai Accent. It seems to me that I hear engine valve knocking. Here tech. details:
- This happens around 1100-2000 rpm.
- The car currently has 11500 KM.
- 3 oil changes so far - using Mobil 1 - 10W30.
- I put in regular gas.
- No mods, only bug guard.
I drive slow - slow acceleration and I noticed sometime ago that there was a knock coming from an engine at about 1400-1700 RPM, however now I can hear it anywhere from 1100 to 2000 rpm. I can hear it very well when I drive along curbs and walls since engine sound bounces off it. I have automatic gear box and therefore I don't know how to test it further ( on manual I would have put some load on the engine by switching into high gear and pressing gas - make engine struggle a bit ). It might be noise from injector but I don't know. Also I don't know if Accent 2010 has self-adjusting valves or not.

I am seeking to identify a problem my hyundai accent model 2009. when it s cool or started with a time period gap between four to five hours. it some times not start with a try of three to four times and then start but giving some knocking sound, it went away after five minutes . once start and warm it is ok and again started when warm.
I did computer check but it result is normal and have changed also the spark plug and fuel filter but problem still exist. the problem may in timing belt -or fuel pump may any other reason.

I have the 2013 Accent with nasty knocking noises from the front. Have the same thing with my 2009. I opened the hood yesterday to fill the washer fluid and noticed I have a gap between the insulator dust cap, body or frame and strut insulator. I can almost poke a pencil through the gap. I am to think this is not normal. I have about 16000 kms on the car.

1) After 10000km the car started to develop some front suspension knocking sound going over potholes. After three trips to a dealer they finally said that it was a loose stabilizer bar which apparently is "very common". They tightened it and the problem seemed to go away. Now after 40000km the problem seems to have came back. I am starting to think that maybe it is somehow related to cold temperature because it seems to get a little better once the car has been warmed up and it has been going for some time.
I don't really care about the noise, but I want Hyundai to fix it if there really is a problem.
2) When driving 40-60km/h with the sunroof open I get a resonant wobbling sound. If I open one of the windows just a bit it disappears. Sounds like a poor sunroof wind deflector design to me. (I have driven Mazdaz and Hondas with sunroofs and none of them had that problem)
3) Whats up with those super heavy 16' aluminum wheels!!!! Is it just me or it feels like they weigh more then the steel ones? The car even feels faster when I put on my winter tires on steel rims.
Other then that the car has been pretty good. I am not getting anywhere near the factory specified fuel efficiency 6.5-7.5l/100km hwy and 8-9l/100km city, but I do drive it fairly hard, so that is OK. It still amazes me though that my 15yr old civic was getting the same mileage with a comparable performance. You would think that there would be some progress in automotive technology....

Pontiac G6 06 Knock Knock. My car is making a knock knock noise from the right front end. It almost sounds like an extension cord plug in end hitting against the wheel well. (Had that happen before with old car's engine heater, this car doesn't have one of those) The noise stops when i break, and I only notice it is driving under 25 mph. I looked under and couldn't see anything hanging or loose.

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

The engine in my 2006 Mazda Tribute seems to have developed a knocking noise. I am not sure what causes it or how to determine where it is coming from.

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.

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.

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 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.

I have a 2007 elantra. I drove it for a while, then my ma needed a car (her tercel was a little unsafe) so I traded her. She loves the car, but as sometimes is the case, her dealer is not very nice. She has a severe side to side knocking noise in the steering- can be easily duplicated by sitting with the car idling and turning the wheel back and forth, even a little. Doesn't correspond with driving over bumps unless the wheel is inadvertently turned by the bump. If the suspension is unloaded (front wheels off the ground), noise disappears. No EPS lights, no codes in any system.
Listened with a stethoscope inside the car- not that loud through column within car. Inner and outer tie rods are tight, noise is not heard loudly with stethoscope through struts, upper mounts, lower arms. Under the car with loaded suspension (rhino ramps), noise is deafening in the rack, with a stethoscope. Dealer told her it needs a steering rack, I definitely understand why they would say that as the noise is clearly audible through the aluminum housing directly below the entrance of the column shaft into the rack. Only TSB I found was for a worm shaft flexible coupling, but the TSB says this is bump related.
