My car has 63 000 km and engine is making loud knocking noise all the time. Dealer took a quick look and he asked head office. Now he wants to run some tests to see which valve is bad. He's hesitating between repairing or replacing the engine. I'm really disappointed of Hyundai quality. I really hope that I get new engine instead of poor repair job.
View 17 RepliesSo my 2012 plugin was parked for about 3 days, and when I turned it on, heard loud knocking and the check engine light came and stayed on.
When switching the car on or off, I'll hear two taps/ticks that were not there before. Loud knocking is not there now.
What can the issue be? It was very cold and snowing.
Weird noise I am hearing with my mothers new Elantra she just picked up. When starting engine has a knocking noise, not kinding. Letting motor run for a few minutes it goes away but is concerning. I was wondering if there is an issue with the MPFI engine which i believe is new this year which replaced the GDI engine. Definitely does not sound normal to me. to me it sounds like a rode knock or hydro lifter issue. Are these engines known for this. My mother traded her 2012 civic for this with 4500 miles. She did not like the seats and dash board layout in it and we got a good deal on this car.
View 17 RepliesThere's a thread similar to this on the front page, but I wouldn't exactly describe my issue as a "rattle".
I've got a good video of the sound it's making here : [URL] .....
It's definitely much louder with the hood up--doesn't seem quite as drastic when sitting in the driver's seat.
I've come across the thread here on the engine rattle/knock fix, but I'm not sure if this is the same thing. Would this be considered a knock?
It's a 2011 Elantra with about 82,000 miles on the odometer. It has an extended warranty on it, in addition to the 100,000 mile powertrain warranty on it, so it's at the dealership this morning.
I have noticed that when the car was in park today right after I started her I heard a semi loud tapping noise coming from the engine... It slowed down when I turned the wheels or played with the brakes... As I went into drive the noise went away after about 20 feet of driving..
What this could be? Is it normal... Just bought the car last week with 45K miles on it and just want to make sure if it is a normal noise or not or whether I should bring her into the dealer.
You know the ticking noise that is normal for our engines? Well, below 25 degrees F, it is the most worst noise ever. It sounds like the valve train is going to explode. Just keep in mind I've driven many cars. The ticking noise shouldn't be outrageously loud.
But my main problem that is worrying me is this WHOMP-WHOMP-WHOMP noise. The higher the RPM the faster the noise. Doesn't matter if the car is moving or not and I know it's coming from the engine. I hope it's not related to the loud ticking. It only happens for approximately 5 minutes. After that, there's no WHOMP sound and the ticking goes back to normal sound levels.
Started up our 2010 RX 350 and there was loud knocking. This smoothed out after several seconds. I stopped engine and started it again. This time the knocking was less severe, but now the Check Engine light is on. Engine seems to be running a little rough as well. I have a feeling I have a bad plug or wire maybe.
View 2 RepliesSo, I am driving, engine starts to knock, i stop, check oil, there is none.... I drive to nearest gas station, put in 4 quarts, still knocks but quieter. Drive back home 75 miles, knocking is incredibly loud. Had oil changed 2500 miles ago, no signs of leaking (Did they put oil in after draining? Hard to prove they didn't) By the time I got home, new oil was black. Is this an engine replacement or can it be fixed?
View 4 RepliesMy engine keeps knocking for a minute or so after I come to a stop and turn off ignition. Should I be concerned?

Today noticed a knockng sound louder than the usual engine knock. It only occurs when we put car in reverse. Checked it with the brakes applied so as to eliminate it coming from any source due to the car moving ie axle/drive connections etc. Putting it in D with brakes on, not moving and it goes away. Put it back in reverse and it recurs.
Tried it even after the engine had warmed to temp guage showing half way. Let car sit for a bit (so engine was still warm) and it repeated. Drove for a few minutes and it would not occur. Shut car off for 1 hour, on restart the engine temp was showing it was still warm and the knock would recur in R.
Lately it has been in the 20's in my area and I've noticed on the first start of the morning the engine sounds very loud and produces a "knocking" noise that lasts a few seconds and then goes back to its normal loud idle. This only happens on the first start of the day...all subsequent starts in the day are fine. (mine is a 2007 model with the FSI engine)
View 11 RepliesI recently started having a very loud knocking noise in my engine and I can't place it. Mostly due to my lack of car knowledge I can only trouble shoot so far. The following conditions are what I can really only go from:.
- when I'm in park or neutral the knocking happens in about 5 beats per second.
- while idling in gear it almost goes away.
- while driving it increases in frequency and intensity the higher the rpms, until it switches gears, then its dull until I get closer to topping out another gear.
- No real functionality of the car has changed.
- I tried doing a mild brake torque, in both drive and reverse, and the engine did not move.
- the knock is pretty hard to locate exactly but seems to come from the passenger side.
I'm hoping it's not to serious because I just filled the gas tank.
Long story short, at 77,100 miles, my engine failed yesterday. I bought the car new about 18 months ago, and have used it for work ever since.
After exiting the interstate yesterday, the car started knocking lightly. By the time I got home (about 3-4 miles), it was barely running, and knocking REALLY bad. No check engine lights or anything, and everything was working perfectly until then. I was sent a tow truck under warranty, and it's at the dealer now until Monday when they diagnosis it. This seems ridiculous for a new Hyundai
My 2012 with 5300 miles on it (oil change at 4400 miles) is now making a pretty significant lower end knocking noise at WARM STARTUP, as in when the car sits for about 10 minutes when I go into the store. It lasts for about two seconds, but it's significant and it's loud. It seems to have started about 500 miles ago and I can't say it was due to the oil change. Oil level is full and clean - I check it every weekend, even on a new car. Could this be a timing chain noise? Don't know. All I do know for certain is that this is very irritating and embarrassing for a new car. People around my car when I start it look at me like and seem to say "Really?"
Cold startup on my car is actually surprisingly quiet, compared to my Nissan Frontier V6.
I am getting a loud knocking noise from the engine on my Santa Fe. The car is very low mileage of around 51K and has regular service and oil change.
Not sure what has caused this but there is a loud tapping/knocking noise coming from the engine. Have got it locally checked with the garage and Hyundai Workshop also but both have suggested that Oil levels are appropriate and they need to open engine to investigate more.
At a higher RPM the sound becomes more loud and recognizable.
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.
I know all Hyundai's 1.8L Nu engines have that quiet ticking noise. But is there a slight knocking sound on the left side of the engine (around the belt area)? Could this be just the timing chain noise? It does this on idle but when on a constant speed/rpm, the engine is quiet.
View 10 RepliesWe have a 2000 Saturn SL2 (120,000 miles). Last night we drove to L.A. and back (from San Diego) , so about 250 miles round trip. For the last 45 miles or so we had the radio on quite loud. At some point in that 30-45 miles the engine developed a very loud knocking noise - like rocks being spun in a tumbler - which we noticed when we got off the free-way and turned down the radio.
This noise did not effect the way the car handled as I did not notice anything when the radio was up. We have been listening to a lot of sounds and I am concerned it could be a Rod Knock - it sounds a lot like this [URL] ... from inside the car, outside it was more of a constant pinging/thunking noise - less gravel sound.
So my quandary is this, our mechanic is not open Sundays so I cannot ask him, but when we take it to him tomorrow, do we drive it or tow it? If the rod is starting to go I do not want to inadvertently do more damage by driving it. The mechanic is 8-10 miles away. We can get their either on the freeway or through surface streets.
Fiance's 09 Corolla S just started having a rattle/knock noise this evening. car has 123k. It's clearly an engine internal sound. I believe it is coming from the cylinder head. She called me when it started making the noise, she shut it off and has only been ran enough to get it on and off the trailer.
Not sure if it's a broken valve spring or valve. or the timing chain guides? It threw a CEL light.
I ran the code on my scanner and it came back with: P0302 (Cylinder 2 Misfire)
My Dads 92 Volvo's engine is making a knocking noise and I'm wondering what the possible causes are. He doesn't take that great care of it but it didn't over heat or anything. It sounds like it is making a loud knocking or clicking noise directly from the engine when you accelerate. It still runs but definitely has a lack of power.
View 6 RepliesI hadn't driven my car for nearly a month and when I returned I noticed a rather loud "clunking" noise when moving the A/T out of park. The sound is coming from the steering column and is quite pronounced. Is it normal?
I am also hearing a sound something like a bad wheel-bearing while accelerating that I never heard before. It sounds like it's coming from the front end of the car.
