Lexus LS 2007+ :: Screeching Sound Emitting From Engine Compartment
Jul 6, 2012
I've been experiencing an intermittent screeching sound that is emitting from the engine compartment. I've attached a zipped sound bite of the screeching sound, starts at about 7 seconds into the recording.
The screeching sound is not audible if the car is moving while in neutral or when it's parked idling. The screeching was noticeable as I gave it gas when parked or was in gear as the car was moving; as though as the RPMs increased a defective belt or pulleys rotational speed is causing the sound?
The sound just started while driving home from the store which is about a 10 min drive, no freeway speeds. I had not driven the car all day and it had been garaged. I had recorded the sound bite once I got home before turning off the car. Restarted the car a few time, sound persisted. Started the car the following day to take to the dealership, no screeching sound, all sounds normal. Possibly engine compartment temperature related?
This is the second time I've experienced this screeching sound, first time was about 2 months ago and had not heard it since until the other day. The dealership was unable to reproduce the sound when I took it in the last time.

I'm getting a very ugly high pitched screeching sound from my belt when the car has been sitting for 3 hours (cold start), or randomly when I turn my steering wheel. Based on that what does it sound like the problem is?

I have an 07 v6 3.6L (50Kmi) that makes screeching sound upon startup for 15-30 seconds. Not belt/pulley noise, more like valve lifters without oil noise. Trying to decide whether to go to the dealer before the power train warranty expires or to leave it alone.

I have a 2007 ES350. It started making a vibrating noise and sometimes screech coming from the serpentine belt area. It stops when I turn off the A/C and also stops when I accelerate with the A/C on (only does it when idling).

I start hearing rattle on my 2010 UL ES350. I think it's coming from either glove compartment or the wood on right passenger front door. It's really annoying.

To get straight to the point: I have a 2013 GTI that has recently started making a screeching noise on cold starts and during engine acceleration (not necessarily heavy load, but actual engine speed acceleration).
I recorded a video of it this morning and it is very easy to discern the sound. The car is APR stage 1 tuned and has a south bend clutch but I don't think either of those are related to the sound. The water pump has been replaced from the service bulletin, the auxiliary belt tensioner has been replaced because it started to make a noise (this noise is completely different). Otherwise the car has never given me an issue, it has been maintained exactly per the OEM repair schedule other then oil changes every 5k miles vs. 10k. I use mobil 1 0W-40 oil.

First off it's a 2008 Prius with 80K on it.
There is a new sound that has started coming from the front of the car in the engine compartment or even lower. It is a turning turbine like sound that is mostly obvious when driving at 60 mph, but my guess is that it is always there, but not as audible at lower speeds. The air and heater are both off and have no effect on this sound. The only thing that could have had anything to do with it is that a day or two before, the tires were low so I filled them to 40 psi. The other thing is that it clicked over to 80K the last week and the friendly red maintenance required light came on.

I have a 2006 2.0t 6mt w/ 60k miles which I bought new. Ever since I can remember when I am stopped at stop lights or driving slowly (less than 10mph), i sometimes hear a knock knock knock coming from under the hood. It normally happens 8 times in a row, perfectly spaced (probably 1 thunk every second). It almost sounds like an electric valve or pump cycling/priming/purging. I would say that this 8 knock cycle happens just a few times a week. I have tried to capture the sound with my blackberry, but it is pretty quiet.

When I park, and let off the brake, the car will gently rock back and forth, emitting a squeaking sound as it does so from the front suspension area. I am replacing front and rear struts (195K miles on my Prius). What the squeaking could be?

I need to locate an unwanted sound from my engine compartment. I am driving a Ford Focus 1.6 petrol engine/zetec (2000), mileage:166 000 km. It's best described as a clicking or ticking sound which is quite distinct. The sound seems to follow the "speed" of the engine.
Most likely the sound is coming from the drivebelt, and maybe from one of the tensioners which the belt is running on.
It's a visible wobble on one of the wheels but I am not sure if this is the case. It does not seem like the sound is originating from the engine itself but I am not 100% sure.
I attached a sound .wav file : ford.wav 1.03MB

How to re-tighten the door. Mine is loose and when closed there's some gap.

My F450 2010 class C motor home has the V10 engine. In the RPM range of about 2200 - 2300, there is a screeching sound I believe is from the engine area. It does not matter what transmission gear I'm in thus the vehicle speed is not a factor - only happens in that engine RPM range. Seems to happen when slowly accelerating or decelerating through the 2200 - 2300 RPM range or continues to screech if I maintain that RPM. If I drop back or increase RPM out of the range it quits. If I accelerate thru the range a little quicker it doesn't happen. Also does not happen when parked and the engine is sped up.

I have a 2011 RX350 and recently noticed rattling sound coming from inside the glove compartment.
I think it comes from the plastic cover of the aircon filter at the back of the glove compartment. This cover seems bit loose even when installed back properly and the vibration (especially when driving over uneven roads) is causing the rattling sound.
I know it's a minor problem but the rattling sound can get irritating at times. My temporary fix is to push back the heavy owner's manual on that cover to prevent vibration.

I've been hearing a loud screech on occasion when starting the engine. For a while, I was not able to isolate it and thought it may have been the HVAC fan bearing or something, because it sounded internal. It hasn't happened overtime, but often enough. The other day, the door was open when I hit the starter and it's loud as H3!!. It'd without a doubt external and seems to taper of rather quickly after the engine starts. At this time, I'm pretty sure it's the starter, but may be belt tensioner.

Ok, best way to splain this is after our Santa Fe has been warmed up and after a short shopping jaunt and restarting there is a brief interim of engine compartment fumes when the heater is turned on. Within a minute this is gone and not a problem but it's as if lingering fumes get somewhere within the ductwork although I cannot recall having this happen during warm months with the ac being on. I've never encountered this problem in other cars we've had. It's not overwhelming and only lasts a minute or so after starting.

I have just purchased my first Toyota. Formally a Subaru man. It is a 2009 corolla XLE with 95,000 miles. It is a one owner car in excellent condition and I have all the service records from the Toyota dealer where the work was done.
When I start the car most of the time there is a rattling sound that comes from the engine compartment and lasts just a couple of seconds. In my manual there is something in the ABS section about noises from the ABS system. Could the ABS system be the cause of this noise?

Found the answer... it's the brake booster pump...

I have an 03 Camry LE with 80,000 miles I do all the maintenance myself it has had the alternator replaced once at around 40,000 miles. The problem that just started is a whistling sound that ONLY is audible after 2500 rpm at acceleration. When the car is in park no matter how much I revive the engine I can not get it to make the whistle sound it ONLY can be heard at acceleration after 2500 rpms.
Also once I cease to accelerate it goes away while I'm driving there is NO Whistling. I've read that it could be the alternator so I had it checked twice on the car and it checked out good it passed all tests. I've removed the belt and spun the pulley to listen for bad bearing but to me sounded fine. I've removed the throttle body boot and checked for cracks an found nothing also cleaned throttle body (not that it needed it) while I had it off.
Also checked air box and nothing. The only thing I've done recently was take out cabin air filter to clean and replaced it but there was no problem with that. What's puzzling is that it ONLY occurs at acceleration after 2500 rpms then stops after acceleration.

I hear a bit of exhaust leak noise from engine compartment only at a cold startup, it goes away in seconds. I am 700miles from home. If it's a nonessential fix i will drive home before fixing, or, if an easy gasket replacement, I have two more days here, and tools,garage, and competent support to diy the job.

After having the rear axle seal replaced 3rd time, my 2004 Toyota makes a sound/noise behind the dash, drivers side, in the engine compartment. Noise is intermittent and only when braking. Hard to describe....electronic sound. Brake pedal feels like ABS system is kicking in. But no ABS light comes on. Mechanics all tell me, "when light comes on, bring it back". Had the brake system flushed today? Still makes the noise.

I own a 2007 Ford Escape. Upon parking in the garage and leaving over night, I have noticed a strange smell. It is unlike any smell I know. I took the SUV to a Ford dealership and he said nothing's wrong. I was wondering if it could be brakes causing it or maybe rotors. Or bearings might have bearing on the situation. I have not noticed any fluids leaked upon the garage floor. Any clue as to what to do?
