Sonata NF (2006-10) :: High-pitch Whine At Highway Speeds
Jan 6, 2006
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?

I have been hearing an intermittent high pitched squeal at 50 MPH and higher. Taking my foot off the gas or taking it out of gear doesn't change the noise. Hitting a bump or tapping the brakes makes it stop momentarily. It sounds like it is coming from the front driver side, though it's hard to tell.
I have about 33,000 miles on the car. My manual says that the brake pad replacement indicator should squeal when the brakes are applied.

We've got a 2011 Santa Fe V6 that's putting out a low pitch cyclical whine at speeds between 5 and 15 mph. It could be making the sound at higher speeds but if it is the engine/wind noise drown it out.
If you're coasting or braking and drop below 5-7 mph, the noise cuts out completely and abruptly. Makes noise regardless of A/C running or off. Sounds like a motor turning on and off. Never makes noise while parked and revved, only while moving at low speeds (stop and go traffic, driving through parking lots, etc) - and is just loud enough to drive us crazy wondering what it is!
Dealer service center checked it out for 3 days - 4 different techs drove it, all heard the noise, but none knew where it was coming from. When you're driving, it seems to be coming from the passenger side of the engine.
On a side note, we first started hearing this noise after we got it back from dealer service, where they replaced the TPS and A/C compressor. I'm wondering if it could be from something they had to move to access the compressor?

I've got a 2006 Prius - yesterday afternoon my wife and I noticed a high pitched whine coming from the front (maybe right hand side) of the car - we don't hear it until we reach about 50mph. It gets louder as we increase speed and then trails off when you step off the accelerator and can't hear it all below 48-45mph.
We bought the car new and are familiar with the various noises the car makes, but this one is new - never heard it before yesterday.

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 2006 accent 1.6l dohc. While doing highway speeds the rpms are very high considering the small engine. There for it give me a result of bad fuel mileage with 480km per 40l tank. I'm curious is there is any 6speed transmission I can swap out my 5 speed with in order to give me that extra gear to bring the rpms down.

During around town driving I am experiencing a faint high pitch whine when braking. This sound is not mechanical, but more electrical coming from the dash-engine area. It is very noticeable when slowing between 40 mph to 20mph.

I have 2002 Chevy suburban. Recently, a high pitch whine has developed. When accelerating the whine intensifies. I replaced the alternator ... No change! What could it be? Speedometer cable?

My vehicle works absolutely beautifully except between 75 and 105 km/hr where I experience sputtering. This does not happen under load but just when I am maintaining a constant speed. It feels like misfires but I don't get a check engine light when it occurs. Misfires would definitely trigger the check engine light. I've tried the obvious solutions:
Used fuel system cleaner in case I got a bad tank of gas
Used fuel additive to eliminate any water in the tank
Changed the oil and filter (it was due anyway)
Replaced the air filter (it was also due)
Cleaned the MAF Sensor
Replaced the spark plugs
None of this has made any appreciable difference in the performance of the vehicle. The sputtering persists.
The car does not have traditional spark plug wires. Instead it has ignition coils which run about $140 each from the dealership. I may eventually have to change one or more coils but I'll try cheaper solutions first.
My next step is to replace the crankshaft position sensor. You may have noticed that I am problem solving starting with the least expensive solution and progressing to more expensive repairs.

I just bought a 2011 accent 5 spd ... Quick question, when I drive it at highways speeds. (65mph) I notice that i am running around 3500 revs. Is that normal? It seems a little high to me. Every other 4 banger I had never ran that high in 5th gear at 65 mph.

I just bought a 2007 es350 yesterday with 67k miles. When I test drove the car, the highway was too congested to get the car above 50 mph. So, the car sounded fine to me and I purchased it with a free 90 day, 3k mile powertrain/engine/transmission warranty. The car should still be under its standard 7 year 70k mile warranty as well, right?
Fast forward to today. The highway was less congested and I was able to get the car up to 80 mph. However, I noticed a constant hum start at 60 mph, which became louder and more high pitch at 75 mph. I am taking this back to the Lexus dealership from where I purchased it to get the sound diagnosed and repaired. I'm hoping it's a problem still covered by the warranty, like the differential (does the ES350 have a differential since it's fwd) or pinion bearings. Could it be something simple, like a bad tire?

I had a rebuilt alternator installed on Thursday and for the past two days when I start up the car there is a high pitch whine coming from what I believe is the alternator. Do some rebuilt alternators make noise when charging the batter after start-up? The alternator has a 3-year warranty and I'm going back to the shop tomorrow.

I've got a 2006 Prius - bought new in 2006. Yesterday I started to hear a high pitched whine or hum from what sounds like the front right side of the car. I hear it when the car reaches about 48-50 mph and seems to increase as you go faster. Once I let off the accelerator the sound slowly goes away. I know there are a lot of noises from the Prius, but this is one I've not heard before.

Our 2008 Honda CR-V w/120k one owner, always dealer maintained, vehicle has recently started exhibiting a little high pitch whine coming from the engine area which increases when you rev the gas. I checked the transmission dipstick and the level is just below the bottom hole (owners manual says it should be between the bottom and top hole). Would this make the whine? By adding some fluid should it go away? Is it okay to use a fluid other than Honda's?

This has happened multiple times but this last time was the dangerous one. I was driving home from work on Friday on the tollway which is very straight but does have some slight turns in it (construction). So I am at highway speeds for some time and one of these slight turns comes up. I try to turn my wheel but nothing happens. I apply more and more force until it finally decides to turn and by that time I am applying so much force, it jerks really hard. If the car didn't finally decide to turn, I would have hit the highway barrier. I am lucky that no one was next to me or I might have hit them.
-This only happens at sustained highway speeds, city driving is perfect.
-It doesn't happen every time I am on the highway, it is intermittent.
-It does not have a bias with regard to direction (left turn or right).
-I have put some Mobil 1 Synthetic ATF in my reservoir to add fluid to my system with whatever was currently in there when I bought the car @ 75K miles. Car currently has 130K miles. Is there some sort of write up for PS maintenance/flush? I need to pull the return to drain, right?
-I do have a rubber on rubber squeak sound in the front right when I go over a bump.

I've been having a problem which i cant seem to find the fix for. My ABS and ECS dash light keep turning on. Its intermittent and does not stay on. Ive noticed that it usually happens if I travel at highway speeds for more than 15miles. I had the brakes x4 changed 1 year ago and all brake pads show good life. Brake fluid is at a good level with no leaks to be seen. I am wondering if its one of the sensors? How can one check for that? I have a 2006 3.3l GLS with 86k.

I recently bought a 2007 Sonata V6, and the brakes pulsate (when applied) at highway speeds, so I am looking to replace the front rotors & pads. I have been told that the OEM rotors/pads aren't great & that as a result many owners have a brake pulsating/vibration issue.

I have a lot of wind noise in my 2 front windows when driving highway speeds, no water leaks. I cannot find where it is coming from either, I assume it is either air rushing over the mirrors or thin glass. Sometimes it is worse than others, not sure if cross winds etc. Is that common in 2009 Sonata. My old 2003 Malibu, much quieter but mirrors were slightly more rounded if I remember.

I notice whenever I'm on the highway traveling between 60-70mph and at part throttle, I hear a hum that I would best describe as a gear whine which sounds to be coming from the rear. I'm taking it to the dealer next week to be checked.

Layely with my 2011 SE I've been getting a low pitch humming noise while traveling at low speeds, mainly going into a stop sign or light and searching for a parking spot. It happens with the AC off as well, not so much a vibration just a low pitch hum, also does it with foot off brake too as I just let it coast. Kind of annoying and want to make sure its good.

My front right tire has been squealing when I turn. It also makes a high pitch tone when driving on the Interstate or at faster speeds. (It might be the wheel barrings - is that the same thing as a CV joint?)
Is the power steering fluid found under the green cap, under the hood? Cause I checked that and it was filled. What do I do? I don't like the squeak when I turn, nor the high pitch constant sound when driving on the interstate. Also I just posted a report about really poor gas mileage. Could these problems be connected??
