Passat (B5) :: Ominous Screeching Sound For About 3 Seconds When Starting Out
Sep 10, 2007
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 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.

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 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've noticed a couple times when I turn on my car with it just sitting there if i turn the steering wheel all the way to one direction i get some sort of screeching sound coming from the driver side front wheel area what could it be and if i were to turn it the other way all the way too. I'll get the sound too what could this be.

I have a 1.8T 2001.5 Passat, Tiptronic with an Upsolute chip. I recently had the turbo replaced (under warranty for the same stock one). After the turbo reinstall, the car did this after driving it a while: I ran it hard and spooled up the turbo good a few times, and then parked the car. I would wait 45-60 minutes. When I tried to start the car it wouldn't start for like 8 seconds on the ignition, and then it would start but in EPC mode!
The first time this happened I panicked, drove it home (just to make sure I got home.) I then tried again and it started fine and no more EPC. Also, if I wait much longer like 3 or 4 hours, it never happens. Since the first time, this has happened like 10 times or more. But now, I just turn it off right after it starts in EPC, turn it again, and it works fine.
The first time it happened I got some kind of codes, but I didn't save them and cleared them. I figured since it happened again, I would get the codes again, but they're not there. I took it to the dealer, and of course, they can't duplicate it. The codes where like speed implausible or not there or something but I can't remember now.
The master mechanic told me to vapor lock was not possible because I had no carb, but I seem to remember that my '83 fuel injects 280ZX turbo had a special cooler fan to cool down the injectors in the event of vapor lock after the car shut down so I'm pretty sure this is possible with injectors. I mean, the explanation for that fan was so that if the remaining fuel in the injectors would get so hot after car shut down that it would vaporize the fuel and the pressure would lock up the injectors.

I have the 1.8L engine with automatic transmission and when I start my car, it has a loud grinding sound that lasts about 3-5 seconds. The Initial rpm after you start the car also idles around 1800-2200 rpm for almost 10 seconds before it goes back to 1000rpm.
The high idling also stops if you shift it into Drive (D) or Reverse (R) but in Neutral (N) it will jump back up to the high idle.
This started occuring november of last year. At first I took it to dealership but they could not diagnose it because they never heard the sound. It ONLY happened when it was cold below 30 F, but recently it has been becoming MORE and MORE frequent and now almost happens everytime I start the car. But it won't happen if the outdoor temperature is above 60 degrees or if I start the car shortly after I shut the engine off (like a 2-3 hour break in between).
I thought it might be a loose flywheel, bad torque convertor, or a faulty electronic throttle control system. I do NOT think it is the starter because it starts everytime even on the coldest of days just that the grinding sound is annoying.

I had major tune up on my vehicle. First I had the timing belt and accessory belts replaced including of course the water pump. I also had the shocks replaced. My question is now everytime I start the car I would hear a screeching noise for several seconds and also when I engaged the a/c. Furthermore, in regards to my shocks when I drive over 60 mph my steering wheel begins to vibrate tremendously.

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.

This has been driving me crazy for the last few weeks. I think my car is making a relay sound, but what it's for. Somewhere in the dash, behind the steering wheel and bezel, on the left hand side, there is a relay clicking on and off every 5-6 seconds. I'm thinking it's for my rear wiper, which I believe my wiper motor is busted. However, I don't know for sure.
So, two things here.
1. I want to figure out which relay it is. Looking for electronic schematic for a 03 w8 wagon?
2. How can I determine if my rear wiper motor is blown?
To be honest, I can't even figure out how to turn it on because the on/off switch for the rear wiper is locked in place. I only hear the noise when I'm not cruisen' with my windows down or when the stereo isn't bumping.

When you turn the blinker on, all of the signals and the flashers work fine, but after you turn the blinker off the blinker sound clicks sporadically for a few seconds, sometimes a minute after the blinker is off. The arrow light and the blinkers don't actually blink, just the sound from around the center console. Sometimes it will click a few times when you haven't even turned the blinker on. What's going on?

My Echo screeches when the AC is on. If I hit the gas, the sound will go away. Also, sometimes when I'm slowing down the screech starts with the AC on. Occasionally, the sound goes away after I've driven about 20 - 30 miles; it appears that the car at idle then is idleing a little higher. And, lastly, on very rare occasions, the screech will start when the AC is off and I turn a corner.

I'm assuming the blower on my 2012 is most likely starting to fail... Called dealer and its special order at $170... I'm not paying that for a blower.

This problem has been happening on and off to my a car for about a year. When I start my car I'll begin to hear this screeching sound coming from under the hood. When I go to drive it the sound get's worse, especially with acceleration. However, after I make a turn or hit the "sweet spot" it goes away. This usually happens at night, which makes me think it's some sort of water/condensation building up on the serpentine belts which are rubbing together creating friction of some kind. Today however was unusual because as I parked my car at school I accidentally left the head lamps on and the battery died. Got someone to jump start me and right as I started the engine...that horrible screeching sound started. I am guessing this is because the alternator had to work harder to get power to the battery? I am not sure. Wondering what I can do to fix this problem.

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 car, a 2006 Nissan Teana, is making a screeching sound when i press the gas pedal. This happens only when the car is moving since when i press the pedal when it is stationery, on neutral, no sound comes out.
My mechanic suspected that the engine belt tensioning pulley was the problem. We replaced it but the noise still there.
Initially, it was not loud and one took long to hear it. It is now getting louder.

See the video, need to figure out this sound. It is currently at the dealership but I don't have much faith in them rectifying the problem : [URL] ....

Ok in the last couple weeks I noticed when I am going left in a curve a grinding screeching sound from what sounds like my left front. It only does it when I am in a curve going left. It wont do it going right or just even turning a corner left just a slight turn.

1987 Acura Integra.... Had the timing belt, belts, etc done.
Screeching sound - I know it is the belts are loose - initially it wasn't there and then it started and it was getting a bit worse slowly. It seems to only happens when the engine is cold.
I went back and had the belts tightened.
Does this tell anything about the mechanic/workmanship?Should I be concerned about other areas of repair that does not have the symptom of screeching?

I hear a metal on metal scraping/screeching sound with the windows down and only when i drive by guard rails and other stuff sound reflects off of. I saw the traveling hub zerk thread and that's what made me think of it. I've zerked every fitting I've seen, but this ones new to me. Problem is I can't even tell witch wheel (if any) it's coming from. It's consistent with speed.

I decided to go for a stroll and about 10 minutes after heading out, sudden the Brake and ABS lights come on along with a screeching alarm sound from the cabin. I pulled over right away to check for leaks and my brake fluid. There were no leaks and brake fluid was full. I decided to head back home and when I turned the car back on, I lost most of my brake pedal and it became completely spongy and would sink down when depressed. I had to drive home with my emergency lights at about 15 miles per hr in hopes of being able to stop in time. I double checked when I came home, no leaks whatsoever.
