Pontiac :: 2004 - Humming Noise At About 20 MPH And Gets Louder With Speed
I have an 04 Pontiac (wifes car) as you start driving you hear a humming noise that starts at about 20mph and gets louder with speed at high speeds it just stay's steady, changes when changing lanes and gets quieter as you slow down, I know its not the engine or transmission as I can rev the engine and only when the car speeds up the sound changes (louder). I've been seeing similar post and its either CV joint or bad bearings but need more of a defined answer from a mechanic who recognizes this situation. Also the sound does make a little vibration felt through the steering wheel and gas pedal but again changes when steering is turned back and forth which I think means it's somewhere in the drive shaft and axle area or steering system.

When my AC turns on or changes speed - a humming sound occurs. It only lasts for about 1 - 2 seconds.
Is this normal
It sounds similar (higher pitched, but not as loud) to the humming you hear when you turn the vehicle off.
Prius (2001-03) :: Transmission Malfunction - Whining / Humming Noise
I began hearing a whining/humming sound just a couple of days ago esp when hitting 45mph and then would notice as I took my foot off of gas. I had hoped it was either tire or bearing related, but Toyota tried for over an hour and finally determined it was transmission related..a new transaxle assy etc would cost a total of 6500$. However, they said they did not think I had to do anything right now as everything is well lubricated..they even thought it could remain the way it is for a year to two. My Prius has 180,000miles on it. Should I attempt to find a salvage transaxle and risk having it put in? Or should I cut my losses and given up?

My wife's 2006 Prius is having some problems. The car has 187,000 miles on it. When the engine starts it makes a continuous whirling or humming sound. WHen I try to drive it has minimal power and can not be driven above 15-20 mph on my street. I bought an inexpensive Actron code reader and got the following codes. P0A92 P0300 P0303 P0304 P3191. Does it sound like a definite transmission problem and those other codes are caused by the transmission problem.

Two things I have just noticed on my '09 with aprox. 120,000 miles.
Starting at about 45 mph, I am getting a humming noise
Doesn't get louder as speed goes up either, stays the same 45-75 mph
Have Bridgestone Ecopia EP422 tires, did rotation, noise did not change location
Noise does go away gradually when slowing down to a stop (after I have reached 45)
I am deaf on my left side, this is hard to tell where it is coming from
Second is this really odd brake pedal clink / pop noise. When brake pedal is depressed fully to the floor, car ON or OFF, there is a clunk
See attached links to the noise.....
Brake pads / rotors are like new, plenty of life on them. I did have the inverter pump replaced per the recall (I read somewhere this could be related?)

Prius (2004-09) :: Humming Noise Under The Hood
I loved my 2009 Prius until this weekend. I just turned over 31,000 miles and now a loud humming noise has developed under the hood while driving. It has not been cold here and this doesn't start until I reach around 24 mph. It remains while the gas engine is running or I'm coasting with the engine off. The humming is there in D or in N and there no sound while turning. When I am under 24 mph the noise is gone. I have set up an appointment with my Toyota dealer for this week, but wanted to know ahead of time if any other Prius owners have had this issue.

I can hear a strange noise from the front occasionally, independent to my operation. It sound like rolling a cassette tape in a old driver. The sound repeats every several minutes, and lasts about 5 seconds each time.
When I standing outside the car, it hears louder from under the bonnet.
Prius (2004-09) :: 2008 - Airplane / Humming Noise In 50 - 60 Mph Range?
I have a 2008 Prius, and I have a couple noises, one of which is related to the airplane noise. I've noticed recently mine starts to make that humming noise in the 50-60mph range (less so at higher or lower speeds). There is 44,000 miles on the car.

Starting at about 30mph there's a humming noise that gets louder as speed increases. It doesn't seem to change if I am steering right or left and i have no steering wheel shake or any sort of noticeable bumping at 60mph. Could this just be my tires making noise, they are quite worn by now.
View 12 RepliesSubaru - Legacy :: Humming Noise From Rear That Increases With Speed
Recently I have been hearing a humming noise that increases with speed. I don't get it when the car stops. I think it's coming from the rear but only when the car is moving and steadily increases in volume as speed increases and comes down as speed comes down. It's not coming from engine or transmission but coming from the rear wheels. Could it be a bearing? or both bearings? Is hard to make out if it's left or right of the windows when the windows are closed. Car drives great and has mileage in the 80's

2007 Camry LE 2.4
I just replaced the rear pads and rotors with no issues other than having to bang the cr@p out of the left rotor with a hammer to get it to come off. Now at pretty much all speeds I am hearing a rythmic humming-type sound that increases and decreases with vehicle speed. It's not a constant hum but more like one-hum-per-tire-revolution type of sound. It is coming from the left side as far as I can tell.
Thinking I had damaged the wheel bearing (and after searching the forums extensively) I replaced it with a brand new bearing from Advance Auto Parts. I re-checked the pads, rotors, all bolts, everything is lubricated properly, etc. Just took it out for a test drive and the noise is still there. Sometimes it gets louder when breaking but not always. I rotated tires and the sound did not follow the tire. The pads aren't stuck or rubbing excessively as far as I can tell.
This sort of thing has happened in the past on the left rear. It would sometimes happen when I swapped the summer tires for my winter tires on steelies, the left rear would make the humming sound, I'd take the wheel off and put it back on 180 degrees rotated and the sound would go away. I've done that a few times too and it has not worked.

View 2 RepliesLexus IS 2014+ :: Humming Noise Coming From Transmission After 185 Miles On Vehicle
I have a 2015 IS250 Base with TRANNY PROBLEMS
After 185 miles on the vehicle, I reported the problem to Lexus and the Tech that test drove with me said I was hearing things. Apparently there was a humming noise coming from the transmission.
The noise became evident and consistent, took it back in again, the Tech says its normal and DI engines make a lot of noise.
After six months and 2700 miles the noise became annoying, Tech said they will look into it and confirmed it is unusual. Test drove about 5 other new 2015, used 2014's and no humming noise present.
Engineers made two trips over a five week period from Cali. They changed the alternator, which at first they thought was the problem, then they started looking at the fuel pump on the engine, then they swapped out a tranny from a loaner and the noise disappeared. They took out the loaner tranny and ordered a new tranny and installed it.
Neon :: 2000 Dodge - Loud Humming Noise Coming From Transmission Area Of The Car
As I accelerate, there is a humming noise that comes from the transmission area of the car. It does not make the noise when I am in idle, nor if i put the transmission in neutral and rev the engine.
When driving slow the noise is very subtle. As I accelerate faster the noise gets louder. The noise becomes the loudest at 60 mph. Above 60 it seems to calm down some. The noise is like a constant, deep humming sound. The noise gets softer as I slow down and then is gone when at idle again. To me it seems related to the speed of the tire or the CV half shafts turning or something rubbing in the transmission as the car goes faster. However the sound doesn't change when the transmission shifts. It stays constant and only gets louder as I go faster and then softer as I slow down.
While driving and turning hard to the left the sounds almost disappears until the car straightens out again. I have replaced the struts on all four wheels and this seems to only have caused the sound to get louder. I have also inspected the CV joints. There doesn't seem to be any cracks or signs of wear to all 4 joints. And I repacked the bearings.
The only other things I can think of is the cv half shafts are actually bad and need to be replaced. Or the motor mounts are not aligned/worn out and need to be replaced. Or the kickdown band and low reverse band on the transmission need to be readjusted. Or the transmission is has a problem (however it doesn't slip when driving).
Prius (2004-09) :: Grinding Noise When Braking At Low Speed
Bought my Prius (2005, with 160K miles) about a month ago and since I've had it I am hearing a metal on metal grinding noise when braking at low speed. How loud the sound is depends on how hard I am on pushing on the brakes. One of my co-workers has the same model and said that his does not make that sound. Not sure if its just because it has after-market brake pads or something? This noise only occurs when braking at low speeds (below 10 MPH) so I assume its an issue with the front brakes.
Is this something I need to get looked at by the dealership? I had a local mechanic that worked on my old Honda beater take a look and he said that the rotors and brake pads looked new and wasn't sure why they'd make noise.
Prius (2004-09) :: Ticking Noise At High Speed
I've got an '04 Pkg IX with about 68k miles on it.
I've noticed that at speeds of greater than 60mph there is a distinct ticking noise (like the sound a bicycle makes when you turn the wheel "tick tick tick"). The noise is coming from the front end, sounds like near the passenger area.
The minute you drop down to speeds of around 50 or less it goes away.
I'm probably going to have to take it in to the dealer since I've already had an indy look at it.

View 5 RepliesPhaeton :: 2004 W12 - Humming Noise In Front End
I have a humming noise coming from the front end of my 2004 W12. I only notice the noise at highway speeds and it appears to only be audible when I turn the wheel to the right. For example, when traveling on the highway and the road bends slightly to the right or when I move into the right lane, I hear a faint hum coming from the wheel(s).
I started hearing the hum a few days ago but dismissed it as a symptom of my Phaeton Obsessive-Compulsive Disorder (POCD). While driving to and from DC last night on a night out with my wife, she commented on the presence of the hum as well.
I just had the LF wheel bearing replaced 2 weeks ago. Here are some possibilities I'v thought of:
RF wheel bearing
Low Power Steering Fuild
Other Steering Problems (leaking rack)
On a related note, where do you check the power steering fluid level? I can't seem to find the reservoir.
Ford F-150 (2004-2008) :: Humming Noise While In 4wd
I went to throw my truck in 4wd the other day and now I'm experiencing a humming noise, but only when in 4 wheel. It's only noticeable when I'm in 4 wheel and I'm off the accelerator or coming to a stop, soon as I accelerate, come to a stop, or take it out of 4wd the noise disappears.
Only other symptom was I tried putting it in 4-low the other day and all it did for a good minute was rev up a bunch, but I switched it back to 2wd and 4-hi and low worked after that. 4wd does still work just fine, it's just buzzing and it's annoying the heck out of me
I did a search, not just on this forum either, all I keep getting is the old "buzzing 'til I put it in 4wd" topic. Hoping to get an answer before I start dropping money trying to find it on my own. I'm not used to these new-style 4wd systems so I'm lost for knowledge here.
