Lexus GX 2004-09 :: Loud Screeching When Starting The Engine
Jan 13, 2015
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.

2001 Prius. Within 15 seconds of starting the engine, I captured the screeching sound from the engine bay. Noise went away after about 20 seconds. New serpentine belt and new 12v battery installed. Pass dealer 27-point check. Transmission fluid, inverter fluid, high voltage battery were replaced about 18,000 miles ago. Current mileage 174,000.
Noise is not from the serpentine belt. I attached a mp3 file of the sound. "2001 Prius Noise.MP3" ..... Which component is making this noise?

I'm having issues with very loud screeching noises on my 08 awd. Sounds like a garbage truck. Lexus said its $625 to replace brake pads and rotors to stop the noise. I'm not really a fan of DIY so is that a fair price for the parts and labor or should I bring it somewhere else?

Everything might be a slight exaggeration. But fuse 14 covers Backup lamp and day time running lights relay coil, A/C Pressure Switch, Redundant Speed Control, Heated PCV (5.4L), Trailer Tow back-up lamps, ABS, Reverse park aid, EC Mirror.
This is a 2006. 4.6L V8, SCREW. I don't have reverse park aid. When the fuse blows there is a loud screeching noise from under the hood. Can't identify it because the fuse wont go while I am sitting idling in the driveway. The parking break i9ndicator comes on, the ABS indicator comes on, Cruise control goes away and the A/C quits cooling but still blows. I assume EC Mirror means Electronic Compass Mirror. So I need to figure out where the short is.

My GX470 has been making a screeching sound when I back up only. It's more of a nail on blackboard sound that comes and goes!

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.

My 97 Nissan pick up, 2.4L I4, 5 speed 182k miles has developed a screeching sound for about 15 to 30 seconds after starting. It sounds like a loose or slipping belt. I have replaced all three belts and the tension is right.
I pulled all the belts again and put them back on one at a time and determined that the belt for the water pump and alternator is the source. I checked all pulleys and components and cannot find anything with abnormal drag or roughness or noise.
I though maybe that I might have put too much tension on the alternator belt and maybe put to much side load on the alternator bearing so I loosened it slightly and that just made the screeching last longer. I also noticed that the duration of the screeching is extended when there is a load on the alternator, such as the blower motor or the headlights.
Once the screeching stops, it does not come back even with sudden changes in rpm or changes in load, i.e. blower motor or headlights, however, every time the compressor kicks on, there is a chirp. Before I replaced all the belts, the compressor belt was slipping on occasion and every time the compressor kicked on, it would screech for a few seconds, but its not AC weather right now.
I pulled off the alternator today and took it up to be tested to see if it would screech on the test set, not a peep and passed all tests. BTW, I am not having any issues with charging or starting, the battery is good. I did notice a wire bundle that runs under the air cleaner has abraded and one wire is bare, I'll address that tomorrow. I don't see any evidence of shorts in the bundle, all the abrasion is on one side and only one wire exposed, and it only touched plastic as far as I can tell.
Also, I cannot visually detect the slipping, the belt and the alternator appear to be moving smoothly, same with water pump, but its hard to tell because everything is spinning so fast. also, it is not bad if you just do a restart after driving, is will only screech for a second or two, but if it cools down, than it back to the 15 to 30 seconds of screeching, and its LOUD.

Yesterday I started the car, backed out of the driveway, and as I was starting out in first I heard a screech-like sound for about 3 seconds, then it disappeared. It sounded like a belt or pulley might be slipping. There was no smell and the car ran fine and quiet after that.
I'm beginning to get worried with this car. I have a check engine light on, the suspension is clanking again, and I saw an abs light for about 5 minutes one day a couple of months ago. My wife claims to have heard a grinding sound in second, but I haven't heard it yet. I'm at 6 years, 3 months of ownership, with 85 K on the ODO. It seems like these cars are designed to drive worry free for about 80K. After that, things just start falling apart. I really wanted to make it past 100K, but now I'm not so sure...

My wife's 2009 Tiguan has 72k miles and is a pretty good commuter. But it has been hot here in Texas, which may have attributed to this problem.
After about 5 minutes of idling, there is a loud screeching noise.

From no issues to this: Can drive in first gear. As soon as tranny upshifts to 2nd, loud screeching. Put it in reverse, and basically no movement and a lot of screeching. Can coast in neutral, drive in third. Is my transmission shot, and if so, what is the cheapest way to get it back ion operation? I.E. Used, rebuilds, etc.
BTW, truck only has 115K miles. Changed transmission fluid and filter at 90K. 2001 Suburban 1500 LT 4WD LSD 5.3L

A problem has started with my son's 2008 Honda Civic EX Coupe 2D....
When completely cold, the engine on starting sounds very loud, a bit like an aero engine. On warming up however, the engine noise returns to normal. This problem apparently started quite suddenly, a few months ago. It is difficult to express a sound in words, but if the normal engine makes a Vrooom sound, then the sound when cold is more like an Aaaaaarrrr. I lifted the bonnet, and looking at the engine compartment, the sound seems to eminate from the left hand side of the engine block.
I did notice that when accelerating from a Stop sign just after starting the car, that I could here the engine revving up over the Aaaaarrrrr noise, and it seemed to be normal.
For reference, I am a qualified Engineer, but have little experience in car repairs. My practical knowledge goes as far as changing the battery, spark plugs or oil/air filters.

When I turn my car on in the morning there is a really loud screeching noise coming from the car....It might be one of the belts. It does it for about 10-15 seconds and then it goes away and It doesn't come back until I let the car sit for a while and turn it on again... What it is?

My jetta started making a loud screeching noise on initial start up, it only last a split second and sometimes it doesn't do it, I read it maybe my bushings need greased, but I didn't know if maybe it was something to do with my flywheel bc with my window down and at idle I can hear a faint tapping noise, I push the clutch in the noise goes away, car starts up fine with no hesitation and also shifts smooth...

My car - a 2007 4 cylinder Hyundai Sonata - is making loud screeching sound more than occasionally but not all the time at high rates of speed (70 - 75 mph) and ESPECIALLY when I am exiting the highway to go to the train station and I turn to the left on the exit ramp. Never the right - only the left, and it stops immediately when I touch the brakes.
About 6 weeks ago, I had 4 new tires put on, and thought maybe they were not installed properly. I saw a mechanic today who put it up on the lift and said everything looks in good order and he could not find anything wrong with the driver's side front wheel, which is where it sounds like the noise is coming from. Of course, when we drove around in it, there was no noise. In fact, after I dropped him off and went to the train station it DID make the noise, so I turned around, picked him up and drove back exactly the same way - no noise.
It is a very, very loud uninterrupted screeching sound.

I have a 2002 Volvo S40. I have recently noticed a very loud screeching noise while driving. It sounds like metal on metal, and it stops when I push the brakes. Any thoughts on what this might be? It sounds like it is coming from the front right tire. I also have heard rattling up there for a while (sounds like something is loose) but my mechanic was not able to find anything with this. I also have issues with my head lights. They go out about every other month and need to be replaced.

1987 Acura Integra Automatic, 160k I have been noticing - mostly for every start (there are a few in between that did not have that sound).
When starting, a loud sound (some what unbearable) heard and was hesitant and then the engine starts. Once started it runs fine. It is not the usual sound that the ignition makes when going bad.
What seems to be the issue? Right after I drained and filled AT fluid, it heard the first time. I have been doing AT fluid since nearly 10yrs ago with Honda fluid. I only did drain and fill and it went smoothly. In 2007, the tranny was replaced. After starting, the car runs smoothly - it is only when starting or just before engine try to start. Batt and alternator tests fine.
It hardly did it today - I might have once heard a girding sound just before starting.

For the past few months I've been hearing a loud fan-like buzzing noise coming from the passenger side of the front of the car. I don't know that much about cars, but it almost sounds like the engine is racing or something is spinning too fast. It has gotten increasingly worse, and seems especially loud at high speeds on the highway.
It is not the heating/cooling fan - the noise is present when the heating/cooling system is turned off.

Having issues with 2009 Honda Odyssey. I'll describe, but I can't be certain these things are related.This morning, battery was dead for no apparent reason. No lights were left on, etc. Battery is brand new.After jump-starting, car ran fine for a few moments, then starting making loud intermittent "buzz" sound from engine/radiator area, down inside maybe on the left side of the radiator. There was also smoke rising from the engine.
I don't know much about cars, unfortunately, but cursory research suggests it might have something to do with the AC system.
I have attached a MOV which captures the sound it was making.

I have an '02 Chevy Cavalier. It was making a screeching noise when I turn for a while and now has started making a loud rythmic clunking noise all the time when the car is turned on. It gets louder and softer but never goes away. It is coming from the engine area.
