Prius (2004-09) :: Humming Sound When Car Is Coasting With Gas Engine Off
My 2008 Prius had a front quarter panel replaced after my wife back in to a fire hydrant.The body work looks fine , no issue there, but now when the car is coasting with the gas engine off you can hear a humming sound that was not there before the repair.Also it does,nt seem to be recharging the hybrid battery at the same rate.My thought is maybe the body shop caused some damage to MG1 by spinning the front tires on a emision testing machine or rollers.Does special precautions would have to be used when testing wheel clearances after a quarter panel replacement on a hybrid? Would a body shop need to do this ?

Noticed the barely audible (with good ears) high-pitched sound that emanates from the car when you let off the throttle enough to prevent any charge or discharge bar from showing? It goes away if you completely release the throttle or if you press the throttle a tad bit more.

Last week as I was returning home I had a strange event in my Prius. I was coasting at about 30 mph when I heard a very faint pop sound a bit like a balloon breaking. It sounded like it came from the right rear area of the car. Afterwards I thought I detected a very faint chemical smell. Could this have been something involving the HV battery?
View 10 RepliesPassat (B6) :: Pulsing / Rhythmic Sound When Going Above 50 MPH
I need to determine what this sound is. We just got an 07 Certified Pre-Owned Passat with about 30k miles on it. We've noticed a pulsing, rhythmic sound when going above 50mph. Some observations:
The sound starts literally at 50mph and is present at any speed above that.Sound is speed insensitive. It is a constant rhythm at any speed above 50mphSound is NOT present when in Park and revving the engine ( I think this rules out the turbo, not sure)Downshifting to 5th and 4th gear does not make the sound go away
I'll list some more if I think of any. I'm a noob with the 2.0T but have the tiptronic transmission in my MKV Rabbit and have never had any issue like this one.
Here's a video I recorded: [URL] ....
I suppose I should've started filming at 50mph, as opposed to a constant 80 in the video. The sound is the same though. You should be able to hear it starting in the first 10 seconds. The sound at 40 seconds is just me rolling down the windows.
Last week the breather valve was replaced because it got stuck and was making a whiney whistling sound. Dunno if that would be related.
Golf IV / Jetta IV :: 2003 - Pulsing Air Sound On Start Up
What this sound is / caused by? This is my Dad's Golf, the sound subsides after the engine warms up a little. It runs fine, power and all. I took off the top timing cover, nope that wasn't it, no rubbing as the sound persisted. Thinking maybe an injector o-ring? The car has 130,000 miles and change on it.

Phaeton :: Pulsing Ticking Sound Coming From The Steering
Funny pulsing ticking sound on full lock. Only noticeable when parking etc. But once it's started making it, it stops when the lock is unwound... but does it again without lock when the car reverses.
There is no feeling through the wheel or through the chasis when going forward... but subjectively it can be felt when going backwards.
Been getting a little bit more prevalent over the last thousand miles. Driving normally, steering feels perfectly normal.
I've checked the power steering fluid. If anything the reservoir is over full.. so it's definitely not short of fluid. Should the fluid be checked from unscrewing the dipstick.. or with is jut dipped in and not screwed up? Either way it's still over the max line.
Toyota - Yaris :: 2008 - Engine Pulsing Sound Over 55mph
I just purchased a 2008 Toyota Yaris. The car is excellent with only one exception. When above 55mph, I hear a pulsing noise - a constant evenly spaced noise similar to an engine that is lightly revving on and off. If I take my foot off the gas, it goes away. Press again while I'm above 55mph, and it pulses again. I have no loss of acceleration, no bucking, and the rpm gauge is steady as she goes. It is an automatic. No noises or anything under 55mph. I'm perplexed.
View 2 RepliesSubaru - Forester :: Pulsing / Crunching Sound From Front Brakes - ABS Light On
My 1998 Forester suddenly began pulsing / crunching sound, from the front brakes. I had just performed full brake inspection 2 weeks before. So I removed the ABS fuse (20 amp), and the problem disappeared. Of course the ABS light is also on now, but I can drive the car. I disconnected the 4 wheel sensors from the car harness, connected an oscilloscope to each, and spun the wheels pretty fast. I get 150 MV peak-to-peak from each sensor. Must I replace the "tone rings", or just wire-brush them? Replacing the rings are a BIG job, and the wheel bearings & seals must be replaced, since they don't survive pulling out the axles from the steering knuckle (front), or strut assembly (rear).
View 3 RepliesKia - Sorento :: 2005 - Pulsing Sound When Turn Left Driving Even On Smallest Curve
I have recently noticed a noise... to describe it would be difficult, but I'll give it a shot. There is a pulsing sound, maybe coming from my front left wheel area? It happens when I turn left driving, even on the smallest curve. From what I can tell, the pulsing sound does NOT change speed when I speed up or slow down. My initial thoughts were a bad wheel bearing, but I'm not so sure. Could it be power steering?
My Kia does have 130000 miles on it, and I just purchased it used a year ago, so I'm not exactly sure what maintenance or repair has been done on it.

Corolla / Matrix 2009-13 :: 2010 Toyota S - ABS Engaging And Loud Pulsing / Creaking Sound
I own a 2010 Toyota Corolla S that I purchased with about 30k miles, I have put about 65k on it since purchasing it. When applying the brakes in dry conditions I am receiving what feels like the abs engaging and a loud pulsing sound/creaking sound. The brakes will pulsate as if I am stopping on snow or ice but no traction control or abs lights will not illuminate. This has been happening for a good while(ever since I purchased the car). I have replaced the front rotors and pads and the problem purists.
The road conditions in this video are completely dry with an outside temperature in the high 70's.... YouTube .....

Noticed a gear lash sound when coasting with the windows open? Is this normal or could it be a stepper motor issue?
View 9 RepliesLexus GS 2013+ :: High Pitched Whistling Sound When Coasting At 60 Mph
I finally got a recording of this, after trying to describe it without much success. Dealer drove the car 2x and claimed they don't hear it.
Video here, turn up your sound... noise happens just as the gas is let off...
As you can hear (if you turn speakers up, recording isn't very sensitive), it's kind of a high pitched whistling sound or whining sound. Happens when coasting (foot off gas) at 60mph. In gear or neutral, same noise. Only around that speed, only when foot off the gas.
What do you think this is? Some have suggested wheel bearing but if you listen this is more of a steady high pitched noise, not a helicopter like sound.
Golf IV / Jetta IV :: 2000 GLS - Knocking / Clunking Sound While Coasting
My 2000 Jetta GLS is producing a clunking/knocking sound from the front end (possibly left-front) ONLY while coasting and going straight. It mostly goes away if I turn left or right and totally goes away when I give the wheels engine power or when I brake.
I recently replaced my front-left control arm due to a thrashed rear bushing. I didn't replace the bearing as I didn't have a pickle fork. Not sure if this is related.
Toyota - Sienna :: 2004 - Grinding Sound Whilst Coasting
2004 Sienna LE with 193,500 miles. While driving home tonight I started hearing a grinding noise from the passenger front wheel. The noise goes away on acceleration and braking. Whenever I take my foot off the gas it starts to make the noise again. It sounds almost like a brake noise but I just replaced the caliper bracket this past weekend and the brakes look great (less than 20,000 miles on caliper, rotor and pads). I suspect a bearing may be going bad and want to know if these symptoms match a bad bearing. The wheel bearings are all original.

View 4 RepliesPrius (Gen 1) :: Pulsing Raspy Noise When Brakes Are Applied?
Our gen 1 has developed a (currently minor) noise issue when braking. I'd like to sort it out before it becomes serious.
The brakes are still strong, and the regenerative system appears to be working. When the brakes are applied (even gently) there is a pulsing raspy sound, seems like it is coming from the front, driver's side. It is more rapid at higher speeds, and louder during rapid deceleration. I guess I'd call it 'grinding', although this is much less unpleasant than the classic 'grinding brakes' I've heard on other cars.
In any other car I would figure a warped rotor or worn out brake pad. But I had imagined that the regenerative system handled light braking, and conventional brakes took over beyond a certain threshold. Now I'm hoping they work in tandem, even on gentle braking and this is just a boring, simple pad issue.
Prius (2010-12) :: Pulsing Vibration In The Front Of Cab When Driving
My car is approx two years old. I bought it in the beginning of 2010. I rotated my tires about 10,000 miles ago after not rotating them for over 20,000 miles. initially the dealer said it was cupping on the tires but I have driven them since for close to 10k miles.
The same issue persists. Whenever I drive the car and it gets to around 30-40 mph accelerating or coasting I hear a very audible noise that almost sounds like pulsating vibration in the front of the cab. I've brought it to two different dealerships and they have both said it is the tire needing rebalanced but I somehow doubt that is the case.
