Sonata I45 (LF 2015+) :: Buzzing Sound Coming From Engine / Louder When Accelerate?
Sep 19, 2014
I cant recall if these sounds were there when i first bought the car, probably because i have the radio on most times. I think the buzzing sounds were present in the last month at least.
After i start up my car and even after idling for a while, i hear a buzzing sound coming from the engine. It gets louder when I accelerate. When I let go of the gas, the buzzing sound lags for a few seconds and then quiets down a little bit, but still can hear it in the background.
I lifted the hood up to listen more closely. I am not totally sure, but i think i can also hear a faint hissing sound ( sounds like leaking air?). I cant pinpoint where it is, but its around the engine.
I also notice that when I am idle, the MPG number in the dashboard is dropping fairly quickly. Like 0.1 mpg every 20 seconds. This is new and started today. I last drove it 4 days ago and didn't notice it happening then and i watch the mpg very closely every time i drive. Could there possibly be some gas leak?

Been driving my Sonata 2015 2.0t for about 14 months, now. Just turned 13.5k miles. I had first noticed this issue a few months into having the car, but didn't think anything of it. At the time, I wasn't spending much time in the upper end of the rev range. Today, I finally decided that it bugs me enough to investigate.
At WOT, starting around 5500 rpm and going until redline, there is a "raspy" sound coming from the motor that I think might be predetonation, but I'm not sure. It isn't very loud, which is why I originally ignored it, but it is easily noticeable inside the car. I've made some modifications in the past few weeks (Intake, OCC, and Exhaust) so I'm starting to have a bit more fun with the car and want to make sure I get this resolved before it becomes a bigger issue.
Out of curiosity, I looked inside the catch can and noticed a couple drops of fluid (lighter in color), which was surprising since I only installed it ~50 miles ago. Any by "a couple drops" I mean maybe 3mL of fluid. Not sure if that is significant in this case, but I figured it is worth mentioning.
I'm wondering if it could just be the altitude (Denver, CO) and the stock tune is off just a bit? I've been looking into the Lap3 Uncle Chip and HKS performance plugs, but am hesitant to go any further without better understanding what might be happening.

Recently my brother in laws truck started making a buzzing sound while running and a much louder sound after it shuts off. Trying to track down the sound. Listen to the whole video because the end is where it gets loud.

In my 2007 Sonata, I hit a poorly placed high manhole cover in a dip in the road, in the dark, going 30MPH, whacked it good before I could adjust...
I then pulled the car over, it seemed to go dead, then the car did crank back up, the engine sounded much louder, like a loud rev/hum, not quiet like usual.
I next drove a mile to a c-store, transmission seemed OK, no leaks, did see a check engine light briefly, but it disappeared. Car cranked OK, headed home, same sound right at cranking and at moderate speed.
Finally, I jacked the car up on the front left, from research appears that the plastic engine shields got smacked good along the front and near the right tire and bent back quite a bit on the left side. There seems to be no other structural damage that my untrained eye could see, just one indention you'll see in a couple of the photos that I think is part of the car design at that spot.
Again, no leaks, no smoke, no caution lights of any kind now.
Photos are attached...
My Hyundai's engine now sounds like a Mustang! Hoping it's just the engine noise from these plastic covers now being bent/destroyed in some spots, exposing the engine and the typical noise you'd hear without them...

I have a 2008 Kia Rondo. Recently we took a trpi. Halfway there, we started to hear a humming/buzzing sound (similar to that of a remote control airplane). It was the loudest when we would stop at a stop light/sign, but would stop when the car was put into park. The noise grew louder and louder as the drive went on. The noise was coming from the front region of the car, but couldn't decipher exactly where. We were able to hear it from the inside of the car as well as the outside. The noise stopped once we reached our destination, but then started back up again on the way back home. Once home, it stopped again and our auto shop couldn't find anything wrong with it. What it could be. Hasn't done it since we've been home. Wondering if driving through the mountains put stress on it. What could be making that noise?

I have a 03 passat with a 1.8t with 126k on it. I just bought the car last week and ever since i got it it has issues i cant figure out
On cold starts its makes a chirping sound under the hood that gets louder as you accelerate but goes away after motor warms up. The sound is similar to a loose or bad fan belt. But the noise is coming from the back passenger side of the engine when you listen under the hood.
Car also has no power. Had a good pull when i test drove the vehicle but now its a dog. It seems like its running on three cylinders or the turbo aint even working
Car is a 5 speed and its a struggle to put the car into first gear but every other gear is smooth. To get it in first you gota be stopped, put it in second then to first and you gota push the shifter left till you feel it pop in gear. Also have to hold it in 1st or it will sometimes pop out...

I bought my RX350 last month and sometimes I notice a strange buzzing sound coming from the car while the engine is off. This noise can come at anytime and usually hours after I have turned off my car. It's difficult to isolate where it's coming from and can last just a few minutes.

Well I've just noticed something quite annoying today... a very slight hissing sound coming from under the rear end of the car. A friend I drove to work this morning even said "what's that noise?".... It reminds me of the sound you'll hear when there is a pinhole in a joint weld, or a clamp is loose? My car only has 2800km on it!

I have a 1983 Toyota Tercel SR5. The car runs really well, however I have encountered a problem. When I accelerate there's this rattle-like sound that gets louder as I go faster. I was with my father and we had to speak louder to talk. He suggests that the noise is not in the engine but could be in the drivetrain. The noise is not changing with the engine RPM, just the car. It goes with the sound of the wheels; the faster I go, the sound gets louder. It sounds serious, but how? What are some of my options? Is it my drivetrain? Or my brakes?

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 have been little irritated with my noisy/rattling sound ride coming from passenger dash, my steering wheel area and some time front passenger belt. I have taken it to dealership and they could not hear anything so they duplicate the problem and no cation was taken. But they found out passenger side ball joint was loose , so they replaced that under warranty.
I wanna know if everyone sonata makes that noise when you go over little bumps on road, rail track crossing ? it just irritates me too much,,how ever the rattle/noise is not much, i cant hear if i have music on.
Yesterday I tapped on passenger side dash and there was a after tapping noise, like vibration. I don't know if its loose plastic or what. I am not able to detect the exact location where the noise coming from. but i am sure one noise is coming from steering wheel on every tiny bumps.
I want to fix it by myself now, cause sometimes noise is there and sometime not. Is there any way to detect the noise ? Noise- more like plastic noise, like loose plastic, hinges squeaking sound, rattling sound.

Eco model (1.6T/DCT). driven 17k miles.
My biggest concerns seem to be the DCT transmission. It's....rough to say the least. It jerks and makes terrible noises in parking lots, which can be quite embarrassing if someone else is in the car. Just today, someone said "is your car okay?" I understand that DCT's are different, but I have driven this car since brand new, and it was never this bad.
The car also seems to shift to a gear that is too high for the speed, making the engine vibrate and sound strained while cruising. This problem occurs around 1500 RPM with the gas pedal pressed and just driving along. I can easily reproduce the issue by putting the car in manual mode, selecting the highest gear possible and then trying to accelerate without hitting the kick-down on the accelerator.
I use synthetic oil from the dealer, changed the air filter already, did the fuel injector cleaner additive and also use ethanol free gas.

Well I have been hearing a rattling sound coming from my engine when I accelerate around 55-70 for a second and then coast. Once I start coasting I hear some type of rattle noise coming from the engine. I just got back from the dealer and was told that the mid-section to my exhaust was bad and it needs to be replaced. The part # is 28600-4z300. I looked it up and it costs $1400 now, but it is on sale for $1000. I am hoping that this will fix the issue I am running into right now.
This problem adds to the list of crap I have been through with this car starting at 4000 miles. First a blown timing chain blows my engine, then my car goes into the shop 4 different times over a month and a half for a overheating/coolant issue. Had to get the engine replaced because apparently my "NEW" re-manufactured engine was leaking coolant into my engine. Now only 2 months since that has been put in I need a new exhaust..

Car has been running rough for a few days. Last night my engine light came on p0017. Called the dealer and they couldn't get it in until Monday. They said if the light wasn't flashing just bring it in then. So I disconnected the battery for a few minutes and the car started much smoother and the light went off. Drove into the city and once I got to my destination the light came back on and the car was running rough again. Decided to finish up and head home. However once I got in to make the drive home I could now hear a rattle when I accelerated coming from the engine. Then the oil light would come on every time I hit the gas to accelerate. I made it home as slow as possible but when I checked the oil it's not even reading on the dip stick and the dip stick smells burnt. No oil on the floor, oil filter and plug shows no leaks. I have noticed the past few weeks that my exhaust tips are dirtier than usual and black drops were all over the rear bumper and back of the trunk. Could this thing really have blown out that much oil. I just changed the oil less tHan 1000 miles ago.

I am a proud and recent owner of a 2015 Sonata Sport 2.0T!
Car looks amazing and am very happy with it.
But lately I have been noticing lots of drone noise coming from the engine, and a really loud cold start as well. The "cold start loudness" goes away after a little bit of driving.
Was wondering if this is just the way the 2.0T sounds, or should i get it checked?

This is my 2011 2.4L Hyundai Sonata with around 78,000 miles(no warranty). For the past two days car wasn't accelerating as it used to and all of a sudden today it started to produce hammering sound. Sounds gets loud with speed. Gears are switching like normal. There is a warning signal also that is attached in the picture below.

I want to know where is the sound coming from? Should i fill any oil? If so what brand and where is the nozzle located.

I have an 2005 F250 4.2tdi XLT. There is a buzzing sound coming from somewhere near the fuel filter area in the engine bay. This started after changing the fuel filter during a service. Its also difficult to start now. It has to swing for 10 secs before the engine fires. What it could be?

I have been experiencing a slight hesitation when I accelerate from a stop. It almost feels like its going to stall for a brief second then it picks up and accelerates normal until I'm at a complete stop again. I have the 2016 sport with the standard 2.4L. I currently have 2200 miles on it now and when I go in for my initial suggested oil change at 3000 miles ...
