Sonata NF (2006-10) :: High-pitch Whine At Highway Speeds
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.

Golf VI R :: Harsh Sound Under Boost Accelerating At Highway Speeds
The last couple of days I've noticed a strange sound that come on under boost accelerating at highway speeds. It's a harsh ssshhhh sound that rises in frequency with engine RPM, sort of between a wood lathe and a bench grinder. happens under mid to WOT. It almost seems like I am loosing a little HP as well but I can't confirm that. It's loud enough to hear it in the cabin and with the windows down I can definitely hear it. It's not really fluttering, that I'm used to being on my 3rd tuned 2.0T

I picked up a 2012 2.5L SE w/ Sunroof and Nav over the Christmas holiday.
I have been driving back and forth between Dallas and Kansas for work and I've notice an "odd" noise at highway speeds. When I have the cruise control set for the upper 70's and the car is in 6th, I can hear, for lack of a better word, a hum from the rear of the car. If I switch the Tiptronic down to 5th the hum goes away. As soon as I shift back to 6th, it returns.
Pontiac - Vibe :: High RPM About 3k While Driving In 6th Gear At Highway Speeds
I drive a 2003 Pontiac Vibe GT (6 speed Manual) and I have noticed that when im in 6th gear going highway speeds, I have an RPM of about 3K. For this model I feel this value is high and im worried about engine wear and fuel economy. I'm not sure about the other gears, but from my knowledge of other cars in the same weight category, less horsepower and 4-speed automatic gearbox, my car should not have such high RPM.
View 12 RepliesPrius (2010-12) :: Balloon Rubbing Sound At Highway Speeds?
The temperature has dropped down into the 30s here and in my 2011 Gen 3 Prius, when I am driving at highway speeds (55mph-75mph), and go over any sort of light bump or rough road (gently rough, nothing significant just normal "imperfect" highway bumps), there is a rattling sound coming from the front of the dashboard where it meets the windshield that can only be described as the same sound that your hand makes when it's rubbing a balloon! Not your normal plastic random rattle, but like "rubbing a balloon with your hand quickly" sound.
I don't mind that other plastic random rattles from time to time (I am not OCD about the imperfections of how much plastic is in the car), but this is obnoxious and I feel like I'm literally driving a clown car. Is there some sort of lubricant or adhesive that is between where the dashboard and windshield meet that has possibly dried out, that the dealership could quickly fix or apply? I'll still under full warranty at 22k miles.
Touareg :: Clicking Sound In Dash At Highway Speeds Like Solenoid Flipping On And Off
I did a search and see that this random clicking sound has been discussed but a source never identified. Thought I'd ask again 'cause mine is doing it more often and it's driving me nuts now that I hear it. Mostly at highway speeds, not tied to any particular function or steering wheel turning. It's like a solenoid flipping on and off. I know I could never get the dealer to replicate it and I assume if many Tregs have it, it's just a normal function but thought I'd ask.
View 15 RepliesTouareg :: Started Making Loud Rumbling Sound At Highway Speeds
About a month ago my Touareg started making loud rumbling noises at highway speeds. It sounds and feels (it makes the whole truck vibrate) like you're driving on the "wake me up bumps" that are on the shoulder. Some times it last for 30 seconds and other times it goes on for the whole trip. It's driving me crazy; however the dealer can't reproduce the problem so they think I'm crazy. It doesn't do it all the time, however, the only common symptom is it happens at speeds above 65 mph. It has happened when it the car was cold and hot, cruise on and off and variable highway speeds. The transmission was replaced right after I received the car due to a malfunction, so the dealer doesn't think this could be a second faulty transmission.

I have a 2007 F150 King Ranch Super Crew 5.4 3v and it makes a ticking sound. I have read about the VCT solenoids and the phasers. My issue is that the ticking noise can be heard at Highway speeds. At it seems to be quicker as the engine speed increase. Not sure what to think. No rough idle. What could this be.
View 3 RepliesSuburban :: 2000 - Running Into Vibration At Highway Speeds Along With A Clicking Sound At Idle Speed
I've got a 2000 Suburban 1500 4WD with the Auto 4WD. I'm running into a vibration at highway speeds along with a clicking sound at idle speed which speeds up and slows down with speed. I've discovered the u-joint on the front drive shaft where it connects with the transfer case is worn and has play in it. Could this cause the vibration?
Also, The front drive train spins any time the vehicle is motion, which is to say the front drive shaft spins as the truck goes down the road, correct?
Golf/GTI VII :: Gear Whine Noise From DSG
I've put exactly 10,075 miles on my GTI as of this writing. The DSG tranny performs very well, and shifts as smoothly as ever.
However - I have recently started noticing gear whine from the DSG. Now, this isn't a subject I'm unfamiliar with, since I had the DSG in my MK6 replaced at about 15k miles after it developed an eerily similar whine, especially in 1st gear. The MK7 whines in almost every gear from about 1500 - 4000 RPM, during both acceleration and deceleration at light to moderate throttle. Granted, it's not all that noticeable with the radio on/if you're not listening for it. What concerns me, however, is that although I'm fairly sure the whine existed in 1st gear since the car was new, I don't remember it happening in all other gears.
Additionally, there is a fair bit of what sounds like flywheel chatter in Park/Neutral. This noise has also gotten progressively worse since I took delivery.
Ford 6.0L Power Stroke Diesel :: Subtle Engine Sound Changes While Driving At Highway Speeds - Surging
I've been noticing some weird, very subtle engine sound changes while driving at highway speeds lately. Something almost like surging, but not. I don't know how to describe it. I might try to make an audio recording next time I take it out so I can explain it.
Anyway, I don't know why but ICP popped into my head. Maybe, for some reason, the engine was varying ICP causing the surging sounds.
So I hooked up AE and did a test. I've attached a screen shot.
With my idle speed actuated as high as it will go, and ICP actuated as high as it can go, I can only get a pressure of about 1450 PSI. I always thought ICP should go higher than that. I seem to recall reading somewhere around 3600 PSI.
So am I misinformed, am I reading the data wrong or do I have a problem? How high should Injector Control Pressure go? I missed it in the screen shot, but ICP is actuated to 100%.
Golf IV R32 :: Whining Noise At Highway Speeds
So my car started to make this noise, hear it more at highway speeds than anything else. It's like a high pitched whine or whistle. When I'm on the accelerator it goes away, soon as I take my foot off the gas it starts up. Just cruising and engage clutch goes away as well. Sounds like coming from rear but hard to tell, hear it at low speeds but not as loud.
View 5 RepliesGolf IV / Jetta IV :: Vibration At Highway Speeds
Driving on the highway the other day and I was doing about 80 and I noticed that the front end started to vibrate pretty loud so I slowed down to around 70 and it stopped. I got home and called up the local tire shop had all my wheels re balanced as I heard that could be the cause they were near perfect. Tires have about 3,000 miles on them. so yesterday I took it out to see if it would do it again and I noticed when it starts to vibrate at about 80 and I push in the clutch it stops immediately. Could my clutch be going out? or possibly like the throw out bearing.

I recently switched from stock rotors to a pair of SP slotted rotors. The pads are stock. I thoroughly followed the bedding process and had no problems until now. For the past 2 weeks I noticed brake shudder when stopping from highway speeds. My first reaction was that it was a warped rotor. Since it was a fairly new pair.

I have been feeling a vibration in my right rear at highway speeds (70+mph) At first i thought that maybe it was a wheel bearing but that would constantly be vibration and it wouldn't be off and on like it is. The car is on coils and a friend mentioned to check and make sure my right height is the same all around. I checked just by comparing the fender well gaps and it does seem as if the right rear is a bit lower. If this is the case, can ur car being a little lower on one side cause this vibration? if so, how?

View 2 RepliesGolf - Volkswagen :: 2002 - White Smoke At Highway Speeds
I'm driving my wife's 2002 VW Golf on the highway to build miles (it's at 84k). It's a manual with gearing that's at 3500 rpm at 70 mph in 5th gear, which seems pretty high. It had been doing fine on the highway, even though the RPM seems a bit high due to gearing, but it keeps me under 80 mph (highway is largely 70 mph). It burns oil, but not too bad, like a quart every 500 miles or so.
Recently, when driving at "high" speed (slightly over or near 70 mph), I get a plume of intense white smoke. After slowing down, the plume goes away, and I can continue near 65 mph.
After this happened today, I put on a code reader, and saw of P0159, air fuel ratio oxygen sensor issue. What causes the white plume of smoke, and what to do about it? Seems like the car should have more miles on it.
Golf IV R32 :: CEL Code P0102 MAF Circuit Low - Slight Whine When In 1st And 2nd Gear
So today i got my first check engine in the .:R. I was merging onto the freeway and i shifted into third rather enthusiastically (didn't redline in 2nd but i was probably at 6k rpm) and put it into 3rd gave it the gas and the tires squealed and I got the traction control light. Has me a little worried since the traction control light didn't go off afterwards. Got off the freeway and pulled into a parking lot and turned it off for a minute and when i started back up I got the check engine light also. Went to schmucks and pulled the codes and the only code I was able to pull up was P0102 MAF circuit low. I highly doubt my traction control light has anything to do with the MAF circuit. I notice when in 1st and 2nd gear (can't really tell about beyond 2nd because there is too much road noise) there is a slight whine. I cleared the codes and the check engine came back but the traction control light never went off.

So I replaced the engine and trans engine mounts on my 2004 R32 today. After I got done and drove it there was some serious vibration and gear whine. It also seemed like I wasn't able to transfer all the power to the wheels, it was definitely slower to accelerate. Did something go out of alignment?
