Sonata I45 (YF - 2011+) :: Engine Damaged - Metallic Pop Sound While Driving
Nov 30, 2015
I own a 2011 Hyundai Sonata with ~40,000 miles (certified pre-owned). I heard a metallic pop sound while driving but did not see anything on the road or in the rear view mirror. Then I got on a highway and couple of minutes later there was no response from the engine (i could feel the car decelerating). Then the engine started responding again. A couple minutes later, again there was reduced response but this time I got a bunch of lights (oil pressure, abs and a few others). I pulled over and tuned off the car. by this time only the oil pressure light was on.
I checked the oil which was near empty. I walked to a nearby gas station and bought oil and filled 2 quarts. Then I noticed that all oil was draining right through in a steady stream.
I had the car towed to a nearby Hyundai dealer. The dealer diagnosis was that there is no drain plug which may be because the last place the oil was changed (around 2-3 months back) did not install the plug properly. He also said that the engine is ruined and will have to be replace and asked me to contact my insurance company.
The last oil change was also done at a Hyundai dealer (a different one than the one that provided diagnosis). I checked my driveway and there are some oil stains, I haven't driven the car much recently and have recently moved into this place so am not sure if these are new or old. What are my options. I don't have the the thousands required for a new engine.

So on my new 2.0T Sonata I noticed a brief metallic rattle in the 2K-3K RPM range when you rev the throttle. I was very concerned.
The sales rep said it may be the heat shielding that is coming lose. He was concerned and said to bring it back when Service is open.
I just got back from the dealer: The service manager didn't know what it was but his tech said it was part of the turbo system, it's a 1/4 inch bar (parallel with the bumper) you can plainly see between the firewall and engine. He said what it did but I forgot to take notes.
I listened to another 2.0 Turbo Sonata on the lot and it has the exact same rattle when rev'd.

In my 2014 Sonato Turbo model, I notice the sound of a vent opening and closing while driving. This is noticed when starting to drive or if the car has been placed in park while idling. My wife drives this car primarily so, I really can't tell when it started or if it has always done it. I have wondered if it has something to do with keeping fumes out of the car maybe. One thing I have noticed though is that it sometimes seems to also make the noise if you hit a bump.

I got my coilovers installed, love em....but now I have a clunking sound. Oddly enough it happens when I'm on flat pavement...not when I'm going over bumps.

I've noticed that when I've driven, park the car in the garage, turn off the engine, trans in park, a loud popping sound coming from the transmission (?) It sounds as if the car is clicking, popping into gear, although it's in Park. The garage is level and the car is not being moved in any kind of way. I sometimes sit in the car to finish a song or a phone call and I noticed this yesterday.

Just purchased a pristine 2011 GLS with very low mileage. The car is essentially mint (garaged + well cared for by previous owner), but has one, occasionally noticeable issue: once warmed up, a very loud metallic buzz/rattle noise is heard from the rear of the car, particularly under low RPM acceleration. I've had many cars in the past with similar noises, which all turned out to be loose heat-shields at various locations along the exhaust systems. With this in mind, I've felt all the heat-shields on my "new" car, and they all seem to be securely in place - though some (especially the rear one over the muffler) seem to be minimally supported by design, and could potentially be resonating with certain exhaust frequencies.

I have been having a grinding/metallic sound when going up hills in 4th/5th gear. It sounds like if you threw metal into moving parts. I believe it's coming from my engine or transmission. When i was at the dealer last month for a campaign and ecm upgrade i mentioned this problem and they replaced the vcm motor assy, however the problem still exists. What could be causing this problem?

I have sonata GDi model 2012 ..the engine is always knocking during driving the car ..I changed the spark plugs, Fuel pump, cleaned throttle as well..some of my friends said it could be about octane range (IKA) but I put it a high quality of gasoline ( premium) and still knocking. There's one thing I haven't checked yet ,is ( injector nozzle) ..

I've got a 2011 Sonata GLS with 83k on it.
Last night I was driving and started to hear a repetitive knocking sound. Stopped to determine if it was only when moving but it continued in park.
Checked the oil and apparently there was very little of it.
Don't know how I screwed that up but the mechanic heard the engine for 1 second and said I need a full engine replacement.
So, yeah I am ticked off and need to take care of it.
The VIN qualifies for a replacement under the recall but I don't know how the dealership will feel about the present engine condition.
If that's not an option, where do I even begin to look for a replacement?

My 2011 2.0t has developed an odd ticking sound from the engine bay that is audible when idling. I haven't been able to pinpoint the source of the sound because once I drop the vehicle in Neutral it goes away although sometimes I do hear random ticks when I do this. The ticking sound is intermittent and sometimes I hear nothing.
In the video at 11 seconds the ticking starts. At 18 seconds it ends as I drop the car in neutral. What this sound could be? I'm going to try to hit the handbrake and check myself or have someone in the drivers seat while I go check but have yet to truly pinpoint the source of the noise.

Been trying to save my miles on my 2011 GLS because I'm right at 100k (99.2K to be exact) and had a feeling something would be going wrong soon. Already had short block replacement, both CV axles replaced, steering columns, seized calipers, transmission sensors, and other repairs all done under warranty work for this stinker.
Driving to work today hear a clunk as I am driving uphill, tachometer immediately goes to zero, engine begins violently shaking, and traction control light comes on for some reason. Had my OBD scanner already plugged in and it pulls P0336 code for a crankshaft position sensor. Fortunately was close enough to home so that I drove it back and took the train to work. Probably going to take it to dealership tonight. The clunk and violent idle leads me to believe its more than a sensor problem. Car has had issues shifting over past month, but was so sporadic and not able to ever be replicated. Would maybe have a hard shift once every 2 weeks. That's about it.

Tonight while driving I heard a rattling noise under the engine, come to a stop and the engine cuts off. I pop the hood, get a jump and nothing. So I check the oil and it is dry... I changed it 4 months ago myself, it is a mystery how it leaked. No light came on, no oil leaks anywhere..
Is there any hope in having the engine turn over again? If so how should I go about trying to turn it? Engine only has 61000 miles on it.

for the last 5 months, i have not been able to use my 2012 sonata which broke down in October last year and has since been in the dealership in Dubai and they have never taken any action. what happened is that the car just stopped when I was driving at normal highway speed. no indication, warning or anything came up. the car just stopped and did not start any more.
when the car got back to the dealership they called me after a few days and told me that my engine block is completely cracked and the whole engine has to be replaced. I don't understand this, the car was only about 16 moths old and has 23,000km on the odometer. the car was always serviced and never driven erratically. until today no one from Hyundai took any stance to the problem

Our 2010 Prius makes a loud metallic slapping sound whenever we drive over the lane marking reflectors on the roads.

When the engine is in gears say 1-3 (doesn't seem to work in neutral or park) when the engine rev's to about 2500 - 3000 RPM there's a metallic vibrating noise that almost sounds like a buzzing/chattering sound. When you reach over 3000, it goes away.
Here's the curve ball - it stops doing this when the engine is really warm. It only seems to do it when cold or it's been sitting a while. So - it's limited to an RPM range between gears 1-3, it goes away when it's warm.
I am inclined to think this is related to engine mounts... And here's why. It seems to only happen when in gear and we know that the engine changes it's pitch/stance when in different gears versus in neutral/park. So I think when it's in gears 1-3, the engine is tilted a bit and something is coming into contact with something (maybe my strut bar) more than it used to due to more slop/movement from my worn out engine mounts. As to why it goes away when the engine is really hot (driven for an hour or so) is because maybe whatever it is that's coming into contact with something else is (perhaps a hose and its clamp?) is much more pliable while warm and clears whatever obstruction it was hitting while cold? (a lot of speculation and creative thinking here).
Anyway - after the engine is super warm and I've been driving it I cannot for the life of me get it to do it... It rev's super smooth and not a hint of any bad sound.... 2011 2.0T Limited ....

I own a 2006 Nissan Altima with about 90500 miles on it. Recently i took it in for service and to fix a problem where the car was making this metallic sound while driving. The mechanic discovered that the sound was caused by a low engine oil level causing the timing belt tension to lose pressure and make the sound.
The mechanic also found a Nissan Service Recall/Campaign (NTB06-082) related to Engine Oil Consumption where the following occurs: "extremely low engine oil level resulting from higher than normal engine oil consumption due to a manufacturing problem in some engines". NTB06-082 states that the first thing the dealer should do if the recall applies is reprogrammed the ECU followed by doing an engine oil check.
What steps I should follow to get the Nissan Dealership to take a look at this particular issue? I imagine that it's going to be hard convincing them that the NTB06-082 may apply to my vehicle.

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.

Recently I started hearing a rattling/grinding metallic sound coming off the right rear while driving slowly. This sound is not reproduced when braking.At first it started while doing sharp right turns only, now its ever present while driving. I showed it to a mechanic he says rotors needs to be replaced. Is he right? 2003 Honda Accord V6....

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.

I am the original owner of a 2007 Camry SE V6 with 95K miles.The car has been meticulously maintained. About 2 weeks ago I started to notice a mysterious sound coming from the passenger side of the engine ONLY when the engine is idling. It has a higher, light pitch but when revving the engine slightly it goes away. Obviously when driving it can not be heard with all the other road noise etc. Also it makes this sound at different times, sometimes days with no noise, very irregularly. I checked that section of the engine bay and see no moisture, leakage or discoloration anywhere. Also serpentine belt shows no wear or wobble. Could it come from the water pump? I am very concerned that something will soon snap off, break and leave me stranded.
