Sonata NF (2006-10) :: 2007 - High Pitch Rattle / Engine Vibration Noise
Sep 21, 2016
I have a 2007 Sonata, 2.4L 4cyl. and it is making some weird noise as of late. I have done some research and from what I have read it seems like it may be a bad engine mount. One thing to note is that the noise really only happens when the car is cold and hasn't warmed up yet or on a cold day.
Basically the best description is that the noise is a high-pitched rattle/vibration noise. The noise seems to match the vibrations of the engine but doesn't seem to get more intense if I rev the engine. The noise does get quieter if I put it in neutral but it is still there. The noise also happens even if the car is parked and off, and I do something like shut the door or trunk. I haven't gotten a chance to get in there and look under the hood myself to try...

I have a '07 Sonata GLS with the 2.4-liter Theta engine and the 4-speed automatic. It has 52k miles on it and has always been serviced regularly. It's been a pretty decent car but is starting to feel a little tired, most notably the worn/bouncy suspension.
Anyway, the other day I was driving down the highway and gave it a little gas to pass a slower car. Doing 60 MPH it downshifted to 3rd (~2000 to ~3300 RPM) and I thought I heard a noise in the engine bay, but I wasn't sure. I ended up needing more power so put it to the floor and as it kicked down to 2nd at ~5000 RPM the rattly noise got a lot more pronounced. Driving around normally I don't hear it but any time I put it to the floor (merging/passing) I will hear the rattle. I can also hear it if I lock it in 2nd gear and give it full throttle up a hill at low speed, like you might do with a stick shift.
It seems like it only does it under load because if I rev it to ~4000 RPM in park in the driveway, there's no noise, even at full throttle. I know the V6s had tensioner issues but I haven't heard much about the 2.4s. I'm not super concerned as it is still under warranty but what might be wrong with it as this is my first Hyundai vehicle, especially in case the dealer can't replicate it.

I've noticed a noise coming from my car (2014 IS350 RWD) that sounds like a light, irregular rattle, when the engine is running in the 3500 - 4500 RPM range. I don't hear it necessarily under load, but if I am in manual mode in a lower gear, and let off the throttle, I can hear it.
The best way I can describe the noise is like a bowl of rice crispies (rapid and random), only slightly louder. You have to listen for it, the road/traffic should be quiet, and if you get back on the gas, the intake noise that's plumbed into the cabin pretty much covers it up. I can also hear it in Park or Neutral.... I've wondered if it's a loose heat shield, or an exhaust issue, but I can't hear it standing next to the car or with my head under the hood. I only hear it from the cabin. The rhythm of the noise is irregular.
I don't think it's ping/detonation, since that usually shows up under load, is much louder and has a decidedly metallic sound to it compared to what I'm hearing.

My 07 SCREW 5.4L 4x4 has 77,000 miles and has a high pitch whining noise on front right side of engine. Sounds worse in the cold,increases with RPMs.

So I'm at my wits end trying to locate (and fix) a loud, high frequency rattle noise inside the engine compartment.
It can be heard when applying the gas pedal a certain amount. In other words, I can "find" the noise and maintain it at a certain rpm.
The noise is coming from the back of the engine near the firewall. It feels and sounds like it's coming from the throttle body plate and vibrating the gas pedal. I cleaned the plate and it isn't loose.
The issue doesn't seem to be affecting engine performance.
The sound is noticeable while driving (under load). When in park, I can find an rpm where the throttle body seems to take a heavy wave of vibration from the engine and hum (but not nearly as loud as while driving). Issue existed before I put on new motor mounts, and still persists after replacing all 4 (although the vibration and noise are reduced).

When I'm driving at a certain speed (usually between 65-70 mph), my 06 Sonata GLS V6 develops a really soft (but really annoying) high-pitched whine that decreases when you take your foot off the gas. Not much at other speeds (sometimes it will kick in real quick at high rpm before the automatic trans shifts), but when the car hits 66-67 mph that little subtle whine kicks in. By 75 mph, it's gone (I drive 75+). Sounds just like a high-pitched dog whistle.
Not a wind noise....sometimes it sounds like it comes from below me, sometimes it sounds like it's coming from the dash. Dealer don't hear anything (of course), even when I'm in the car with the tech and can hear it (maybe I'm part dog.....who knows).
Here's my guess.......I think that it's the electric fuel pump. Sometimes if I'm outside the car, I'll hear a whine back in the fuel area that is almost the same pitch as the whine I hear at 70. Since the whine varies (or disappears) with engine rpm and application of the gas pedal, my thought is that I'm hearing the fuel pump hit a certain pitch, which causes the whine.
2006 Sonata?

Sitting in parking lot listening to ipod thru aux port opened door to access door pocket and sound system went nuts. I now have a high pitch noise coming through all speakers on all settings even with audio off.

The car required a new water pump, the mechanic suggested to also replace the serpentine belt because of age - after a week the car made high pitch noise when started, the noise stopped after the initial start-at the shop it was explained that a new serpentine belt requires tightening after the car has been driven for a while - like a week- is this correct or was the belt not installed correctly....

I purchased a new 2011/2012 Santa Fe (R2.2 VGTi Auto 7 Seater GLS AWD) recently and noticed a high pitch noise on the audio system. This high frequency disturbance is audible with the engine off (eliminating the alternator as being the source). This is also present with the volume set to a minimum.

I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.
Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?
Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?

I have an 03 2.0 jetta manual shifter. Never had issues before this morning. Got in car and sounded like it wanted to turn but wouldnt turn over. After a few attempts the turning sound stopped and I heard an electric pop. Now engine won't even try turning when I turn key it just clicks and engine makes a high pitch noise. Took starter and battery out got both tested and they are fine...

I lost boost, went from being chipped at 16psi to 7-8 with a check engine code and a high pitch noise. Now is the secondary air pump connected to the turbo in any way. It just happened and I'm working on getting the code read. Just curious if my pump is just bad, what im figuring.

I went to go start my LS460... put the heat on, its fine.. when I turn the heat up on high I get this annoying high pitched sound. It has to do with the heat system because when I turn it off it goes away... I'm scared to keep the car running...

Went to have an oil change....service rep came in with my cabin air filter and said it needed to be replaced, I told him "later" as they charge too much for a simple filter.
Two days later I had the need to run my blower on high and it vibrated rather loudly.. I tried different positions on the vent switch but nothing worked.. then it came to mind the Jiffy lube incident. I went in and pulled the cabin air filter out and saw nothing wrong there. Upon further inspection I found a piece of an acorn in the blower wheel.
Moral of this story...if you changes cabin air filter, be sure to check for any debris that may fall off the old filter into the blower wheel when it is removed.

I just put a dual exhaust kit on my truck (cherry bomb extreme, single in dual out), and I've started to notice that around 2100-2200 RPMs, there's a high pitched vibration in what seems like the tight hand corner of my regular cab. It almost sounds like the glass in the window is vibrating, or a loose bolt, or something like that. Very high pitched, very noticeable.

I replaced the timing belt an waterpump at 262,000 miles and ever since the engine makes a loud low pitch noise that varies in pitch depending on the engine speed. I replaced the alternator and it didn't work. I don't know if the power steering pump, a/c compressor or something else is making this awful sound.

Any way, my 2007 Sonata with 57,000 miles just developed a whining noise on the right side of the engine compartment. It sounds like it is concurrent with RPM and I thought it might be the alternator, the drive belt or some pulley. I have even seen on the general internet that some others had a bad oil filter. To me, the noise seems to be coming from the alternator area. It is a relatively high pitched noise that almost sounds like an electric motor. Would love to get it fixed. I am nearing the 60,000 max on replacement from certain items and do not know if the alternator is covered.

According to the manual the high pitch sound is to let driver know that the pads are worn out but i checked and my pad still very thick after 15k miles.?

Car wouldn't start, would just kind of do a high pitch whining. Bought new battery and still does it. It might crank right up or take up to 5-6 times. I'm a second owner and I believe it is the starter.

I got a 2007 Hyundai Sonata Limited, 6 cylinder, 3.3L, at 110,000 miles and since I bought the car, I always had a vibration when the A/C is on. I can feel it in the front of the car somewhere where the pedals are. Ones I turn off the A/C I can feel how the vibration causing thing stops. Is it normal? Can it be one of the A/C motors?
