Sonata I45 (YF - 2011+) :: Buzzing / Chattering Sound When Engine Revs To About 2500 - 3000 RPM
Feb 19, 2016
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 ....

2011 Sonata GDS. I previously purchased 19" Gen coupe wheels and never had a problem immediately. Approximately 2 months later of driving with the 19" wheels, when I got onto the highway one day, the car did a slight jerk with acceleration and the acceleration halted for a split second. Ever since that day, anytime I accelerate fast and/or reach highway speeds, the car has a delay when I hit the throttle. The car then has a "rattle" "groaning" sound that comes when the RPMs hit around 2000-2500 rpm. It will go away if I drive slow speeds/slow RPMs or shut the car off for a short amount of time. I have taken my car to the Hyundai dealer 3 times. I've had the adaptive values for the transmission and engine reset and that didn't do anything. I had a mechanic ride with me in the car to make sure they were hearing the sound and the delay in shifting and the mechanic was very shocked and had never even heard a sound like this before.

I have been noticing that the ballasts have been making buzzing sounds a lot lately. Is this something normal that is suppose to do? I have the slim ballasts from xenon supply.

The rattle, 1.8t GLI
-2500-3000 RPM
-Car can be in gear or out of gear, rev rattle is the same.
-Sometimes, I can hear the rattle when the car is off and I slam the door slightly harder than usual.
-My hood release cable may have been the culprit, but I could only zip-tie part of it and the rattle hasn't changed.
One really important clue is that when I have reached around the area between my engine and airbox, the rattle has gone away. So I had a bad coolant flange, so when reaching my phone down there to take pictures, I must have bumped or pressed something because the noise was gone for about a mile.
I recently had my airbox out and a visual inspection didn't show any promise and tapping on random parts didn't recreate the sound.
There is am RPM rattle near my airbox....

Manual... I hear this buzzing sound, mostly during deceleration, on 2nd, 3rd or 4th gears between 2300-3000rpms, very annoying on 2nd and 3rd gears, but can still somewhat noticeable on 4th gear. Can also hear it on acceleration, sometimes on 2nd and 3rd gear, silent on 4th gear.
I've turned off soundaktor thru VCDS, but still hearing this sound so I was thinking that the hockey puck is still spinning, albeit not as annoying as when it's 100%. So I tried to disconnect it, still hearing that buzzing sound. I even removed all stuff from my car and it's still buzzing. Really annoying, specially if you just want to hear the sound of the engine braking on deceleration.

MT 2500 Where are you I've got a weird one. 99 Chevy 5.7 dully dump truck. The engine cuts out while driving at 3000rpms only. If you keep your foot in it it goes away at 3200. Does it in any gear(auto). Also, stopped and in park, it will do it at 4000rpms. Acts like a rev limiter. Fuel pressure does not change (60-62psi) when this happens, does it in open or closed loop. I disconnected the maf and no change. I've installed new cap, rotor, plugs, wires, coil, module(all original with 165K), no change. Runs sensational until 3K rpms.

I've been getting a blinking engine check light.. I pulled all the codes:
P0050: H02S Bank 2 Sen 1 Heater Circuit
P0155: O2 Sensor Heater Circuit Malfunction Bank 2 Sen 1
P0304: cylinder 4 Misfire detected
P0688: ECM/PCM Power relay sensor circuit
I've had the car sitting for awhile because I lost my job and didn't have any money to roll it around much.
I just changed out the spark plugs and two of these had a white coating on them.. I was hoping this would take care of the misfire after I replaced them. I also bought a new battery because mine had lost charge a few times.
The Car will run with an engine check light, but if I go past 2500-3000 rpms then it will start blinking (which means don't drive it )
The oil has been sitting in it for about 2 months, so I'm about to go change that and I'm hoping this will allow me to drive it without issues.
Any of these codes thrown and know what they could be? Which O2 sensor (like a link to a website that sells them). Trying to get this thing running again.

I recently purchased a 2013 elantra.
I have noticed that there is engine vibration and noise felt in car and pedal when accelerating at around 2500-3000 rpm's before it shifts. Is this normal behavior? It just does not seem as smooth as it should be. I have only put about 600 miles on the car.
It has been very cold, but it does not go away after warming up.

Today I went out to crank my Sonata SE 2.4. Pressing the ignition button only got me a buzzing and no turning of the engine. We've been out of the country for 2 weeks and the car has been in the garage since then. I have a portable battery booster that I attached to the battery and the car started normally. I drove it for around thirty minutes and switched it off in my driveway. Immediately tried to restart and it would not start. Boosted again and headed to Auto Zone to have the battery tested. Battery tested bad so I had it replaced. The car started immediately so I turned it off and tried to restart as a precaution. No go.... boosted again and cranked fine. The new battery tested out good so we decided that maybe the charge could be low or? maybe we just needed to run it some on the interstate.
I now had a cel on. So we get out onto the interstate and drive about two miles and the engine looses power, limp mode ?. Pull to the side of the road and RPM's at only 1500 with the accelerator to the floor. I was afraid to restart the engine that it would possibly not restart and I'd have to be towed.
Luckily, we were about two miles from the Hyundai dealership so we limped there at 20 MPH. The car is at the dealership now being diagnosed.

2006 Explorer with a perplexing issue that I am scratching my head over. When engine revs to around 3000 RPM, there is a click that sounds like it is under the dash, and the ABS, traction control, and airbag lights come on; if the headlights are on, the dash lights around the a/c controls go out, and sometimes (but not every time) the speedometer and odometer drop to zero. Also, the overhead lighting, if on, goes out. The engine does not appear to be affected. After about 1 second, another click, and everything returns to normal. This happens either while driving or if in park and revving engine. Is this possibly a relay tripping? And if so, why is it triggered by 3000 RPMs?

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?

Oil in my 2012 Sonata 2.4L is black on the dip stick in 2000 to 3000 miles. Dealer says normal for this car, I don't believe it. What do others see? Also only gets about 32 mpg on highway and has black deposits on the tailpipe. I have gotten better than rated mileage on every other car I have owned so I don't believe it is my driving technique.

I have a rattle coming from the muffler when I reach 2000-3000 rpms. I thought it may be the heat shied, so I got underneath the car and it was nice a snug. Had my wife get in the driver seat and rev the engine. It seems as though all sound came from the outlet of the muffler. Do I have an internal failure in the muffler? Over the past month it has become louder.

On my drive home today around 2500-3000 rpm I am getting real bad lifter ticking noise. When I let of the gas it stops but as soon as I get back on it it will start ticking again. I just bought oil for an oil change Mobile 1
0W-40 I'm pretty sure plus a mobile 1 filter. Will this stop the ticking noise or do I need to adjust my lifters?

Don't know if I'm experiencing the dreaded limp mode or not. It seems that SOMETIMES while just digging thru the gears 1-2-3, not hard, when I get to 3000 rpms it's like I'm taking my foot off the gas. Rpm drops from 3000 to 2500. It's like I'm losing boost or something. I have no mods and obviously, no boost gauge.

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?

Ranger often wants to idle at 2,500 to 3,000 rpm. I'm glad its got a clutch! This is a long term intermittent problem that is getting worse. I have replaced the the IAC twice. I have unplugged the IAC when the engine is in high idle and the engine idles normally. But, starting the car with the IAC unplugged makes car run rough. That makes me think the IAC is not getting the right voltage input from the pmc (eec). Mine is a 2002 with the 3.0 engine. Throttle plate seems to be closed.
What sense inputs does PMC use to determine idle air position? Also replaced TPS sometime ago but that didn't work either. Sometimes turning off the a/c will knock the idle back to normal but not always. Turning the car off completely usually resets idle. But the high idle comes right back after accelerating. Drove the car today and idle would stick and stay high when clutch pushed in coming to a light. However. as the car slowed to a stop the idle would come down when rolling 1-2 mph. ??

I have a 2012 Sonata GLS with 3300 miles on it. I have noticed that now that the temperature has dropped to below 60 degrees I have annoying dash rattle. It seems to be based on the rpm of the motor (1200-1500 rpm). So every time I take off from a stop sign or stop light I have this buzzing rattling coming from the center of the dash. It sounds like it is in the upper part behind the radio. The wife drove last night and I put my ear on the passenger side vent by the radio and I could hear the rattle. I am just trying to isolate the problem so when I go to the dealership I can give them some decent information. I thought the problem was the cowling on the bottom of the windshield. In the center of the window it had warped up. They replaced the cowling earlier this week and the problem is still there.

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.

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.
