Lexus GX 2004-09 :: Whirring Noise From The Engine / Smell From The Car
Aug 1, 2013
My wife has an 07 GX470. Two days ago she came home and mentioned there was a whirring noise from the engine. I started the car, lifted the hood and heard the noise. Sounded like it was being generated by the serpentine belt. Meaning, something that the belt was "driving" was making the noise. She drove it again yesterday morning for a 10 mile trip to drop off son at camp. When she came back, she indicated that it smelled. Just walking out the door to the garage I was hit in the face by a very strong electrical smell. No fire, but smelled very bad. Car has been sitting since yesterday morning and she just now tried to start it and the car is dead. no power to anything. Battery is new 3 months ago.

I've got 2013 es 350 with 10,000 miles on now. I have recently noticed that there was whining/whirring noise coming from the engine(I guess) while accelerating up to 45 mph. It seems that the noise goes along with the RPM since it gets louder when accelerating. It makes same noise when decelerating from 30 mph and it goes away when the car stops. A friend of mine drove the car once before but did not hear anything until I told him about the noise, so I guess it is not very noticeable to some people. At the 10,000 miles check up at the dealer, I mentioned about it and they said they did not hear anything, but I know for sure there is whirring/whining noise.

I have a 2006 lexus es 330 that just turned over 90,000 miles. My dad and I have done the regular maintenance on it so far but this weekend after a 3 hour drive, I turned the car back on and a loud whirring/humming/whining noise was coming from the engine. It gets slightly louder with acceleration, but I can barely hear it once I've picked up speed (but it's still there.) It still happens when I am in neutral. It sounds like it is coming from the passenger side of the engine. Close to the power steering pump area, but the power steering fluid is full (although it is a very dark/black color and has a slight smell...not sure if this is normal.) I'm not having any trouble or hesitation while steering. The rack is operating smoothly and it is not leaking. I plan on taking it into the shop but wanted to go in educated.

2008 GX with 42K and just driving home and battery light comes on and a whirring noise--pull over and open hood smell strong electrical smell--ok Alternator fried. Got it home and battery light off but still when I put a meter to my battery with engine running its only putting out 13.4V? should be at least 14.5-6 correct. Has to be Alternator cause of the symptoms and the burning electrical smell..
SO WHO has changed alternator and how hard was it? Im looking for it and I think its under the Power steering pump it seems left side engine looking at it.??

2007 GX470 120,000 miles. Great vehicle and no problems until now. Seems I have an intermittent engine whine/whirring/zinging sound. I say intermittent because sometimes it there and other times its gone. It is fairly loud. Almost like an extremely loud alternator whine, only this sound is coming from the area near the ac compressor. There is some plumbing which runs just along the left side of the compressor pump and when I grab those lines and the little aluminum cannister in that area, I can feel the vibration in that system, big time. No vibration from the compressor pump though. Not sure what those lines are, but whatever they connect to is probably the culprit.
Its odd because the noise comes and goes. It doesn't fade in/out. It's either full blast loud, or totally gone. Once it's gone, it doesn't come back for a few days. Then one morning i go out and start the truck, and there it is again! Usually lasts for about a day, then it goes away for a week or so. After a week goes by, there it is again! Really odd. I had my mechanic look at it, but it wasn't making any noise that day (as luck would have it). He told me it was an awesome vehicle. Of course I agreed, but that didn't diagnose the problem.

Having a fan like sound apparently coming from the gas tank, but different than what everybody is saying is the fuel pump- its not a whirring sound under the drivers seat and not while the engine is running. I have heard this a couple of times after the engine has been off a few hours of sitting in my garage, and then after a few minutes it goes away. The last time, I opened the fuel filler cap and the fan sound stopped immediately.

Question to everyone who drives an Azera out there. This is regarding the 3.8 V6 engine.Does your engine make a whirring noise at around 2000 rpm? Sounds almost like a supercharger whine, starts at around 1800 rpm and continues up to the low 2000 rpm's. It's not a loud noise, only audible with low volume music or none at all.

Upon arriving home a couple days back, a rather high pitched whirring noise commenced while idling. The pitched changed seemingly at random. So I popped open the hood and set about locating it, using the time honored scientific method of leaning over the engine, listening and moving around till the noise was most prominent. The noise has not recurred.
Seems to be coming from under the cover at the back. Area of interest circled in the 2nd & 3rd pics.
What is there, and if it might make a whirring noise. I am also getting a p0491 and 492 Secondary Air Injection Insufficient Flow, banks 1 & 2. Wondering if this could be the culprit for that as well.

I have a 2005 Prius with 218,000 miles. Over the past month or two it's started making a horrible noise, which has finally gotten to the point that I can barely stand driving it. I used to keep my radio around 25 or so, but now need to crank it to twice that to hear anything. I can't tell what it is - it sounds vaguely like wheel bearings, but somehow different. The front bearings and a trans drain/fill was done by an independent shop 6,000 miles ago. That shop says the noise is the transmission and definitely not the bearings. My Toyota dealer says the noise is the bearings and definitely not the transmission.
Here are two videos I took this afternoon, which seem to more or less capture it, though it does sound a bit different recorded on a phone than in the cabin:
(this one has a clearer example of the noise)
Background:
I didn't have any complaints with the car until just before the 200,000 mile service was due, when I started hearing front bearing noise (I've had bearings done in about 5 vehicles, so it sounded pretty obvious to me). I brought it to the dealer and was quoted an outrageous amount for front hub assemblies (they told me they couldn't do the bearings, only the whole hub assembly), sway bar end links, alignment, transmission flush, tire rotation and the engine top end service.
I got a much better quote from my local mechanic who I've used for about 3 years, so I had him do the work. This was back in June, at 212,417. He said that they'd never done the flush on a Prius transmission before, but they had the shop manual and were sure of the procedure, and that their Valvoline rep confirmed the correct fluid, and gave them a written warranty in case of any problems. He did note that "a fair amount of metal shavings came out with the old fluid" when they did a drain and fill (not a flush). He also told me that the tires were worn unevenly so I could expect a bit of road noise after the rotation and re-alignment. They an oil change, sway bar end links, front bearings, tire rotation, alignment and reans drain and fill with Valvoline Max ATF, "Toyota Type WS fluid spec." He told me the same thing about the front hubs being complete assemblies, and the part he listed (PBR930641) appears to agree with that.

While driving, hear a whirring sound, happens about every ten seconds, lasting for about two...after getting home, shut off engine and this sound continued. Turned on, turned off, still continued. When off, occurs about every 20 seconds.
Continued for the 10-15 minutes I was in the garage. Opened the engine and definitely coming from under the Synergy Hybrid box.
Went out four hours later, and quiet. When I opened the door, sound went on again, lasting for 20-25 seconds....It then stopped and started again, occurring every 15-20 seconds, lasting for about 3 seconds.

I am experiencing this whirring/grinding noise:
Which is the same as this thread : Grinding Noise from Dash | PriusChat
It occurs intermittently when starting up the car, though if I then turn the car off (as in my video) the noise continues.
On that thread the vehicle was in warranty and was fixed by replacing the MFD touchscreen. My 2006 UK Prius is (I believe) out of warranty, and the touchscreen/MFD seems to be working fine. Is there anything I can do preventative on this?

I have an 02 Blazer w/ 110K miles. It's the 4.3L with 4WD. When I start it in the morning it usually has a low pulsing whirring sound for up to 30 seconds. It then goes away until the car is parked for a long time again, say overnight. It's a low volume sound, a lot like the sound of off road tires running down the highway. This has been going on for several months now.
All systems work fine. The alternator is new, the water pump has about 29K on it, and the top idler pulley has been replaced. Turning the A/C on or off makes no difference. The sound is loudest when you stand in front of the passenger side headlight which made me suspect and swap the alternator.
Could it be the belt? It was replaced with the WP and the ribs are not smooth inside. They are notched. I assume that's to improve the flexibility of the belt. If I take it to a shop they'll get 30 seconds each morning to diagnose it.

I recently replaced the water pump, timing belt and all other belts in my 2005 Elantra. The car runs great, but there is a whirring/whining noise at idle when I have the car in park and in drive when I'm stopped at a light. You do not hear the noise when I accelerate and you do not hear the noise at any speed above idle.
At idle the whirring/whining noise can be heard whether the A/C is on or off. I have done some research and some causes for a noise like that have been a bad power steering pump, alternator, or pulleys.
The Elantra has 106,300 miles and gives me 26 MPG. I love this car. It has been the most dependable car I have ever owned. I plan to maintain it and hopefully last me for another 100,000 miles.

So every once in a while, my A/C starts to sound like it's struggling. The force of the air gets stronger and weaker, and it starts to make a whirring noise (much louder than it should be). The temperature is fine, it's just the blowing air.
It will continue like this for weeks or months, then eventually when I start the car (particularly if I'm in my parking garage at work for some reason?!?! - could be a coincidence) the A/C won't blow at all. If I hold my hand near the vent, I can feel cold air - but it's just sitting there, not getting blown into the cabin.

My girlfriend just picked up a 2007 Prius Touring, 78,000 miles, original owner. It was a private sale and I took a look at it for her. I'm just learning about the Prius and stuff to look for, but everything looked good on it to me. After purchasing it she noticed a noise coming from the drivers side dash. I searched here and saw that dash rattles are common, but this sounds more like an electric buzzing/whirring noise. The duration of the noise is always about 2 to 3 seconds in length, then it stops. There doesn't seem to be any common factor for when it occurs. Is there anything electric on the drives side dash (far left side, closest to the window), that might be making this noise? It's not super loud, you can't hear it if the radio is on.

My 2004 Chrysler Sebring with 128K miles is making a loud whirring noise when I accelerate. It does not happen when I break, coast or am idle. I live in a city and potholes are a way of life. I got four new tires in November and had the alignment checked and fixed at the time. What it could be?

Here is a link to the audio [URL] .... It makes this noise, whether I'm at idle or running, granted it seems to be happen more when moving, its quite intermittent as it stops sometimes. I replaced the serpentine belt a month ago, so it can't be that. Its coming from the front of the engine. Sounds almost like the fan bearings or something below that is scraping. I've turned off the heater and it still does it, but the fan is spinning all the time, so I'm not sure what is going on.In the background you can hear cars going by on the overpass above, but I'm focused on the grinding noise. Car is not moving, its in park and makes the noise when moving also, with gas or at idle.

I just purchased a 2013 Ford Focus hatchback SE Monday night. Tuesday morning I came out of the house to get in my car, I unlocked the car, and opened the door. Before I even got into the car I heard a "scratch scratch scratch whirr whirr" coming from the engine. The dealer did not show me where the hood latch was so by the time I figured out how to open the hood the noise had stopped (within a minute of when it started.) Driving that day I did not notice any more noise, nor any issues with the engine.
Wednesday morning (today) I came out to get in my car, and when I opened the door I heard the same nose coming from under the hood. I got the hood open and looked in with a flashlight while the nose was still going. The noise was coming from the right hand side of the engine block, but I did not see anything actually moving to cause the scratching and whirring noise.

My 1999 Honda Accord is making a whirring noise sometimes. It happens occasionally, now more frequently than last month. It sometimes happens when I start the engine, but am still in Park. Mostly it happens when I'm actually driving. both slowly on back roads and fast on the highway. What would cause this?
