Golf IV / Jetta IV :: Engine / Exhaust Makes Loud Humming Noise At 75 To 82 Mph?

2005 jetta. On the highway when I hit about 75mph I hear this loud humming coming from either the engine or the exhaust, I'm not sure. It disappears immediately once I cross about 82mph. What could this be? Why such a specific range?

Prius (2010-12) :: Makes Loud Rattling Noise As Soon As Engine Kicks On

I got in the car today and started it... I was waiting a few seconds for someone to get in the car (it was in the garage) and as soon as the engine kicked on there was a very very large long rattle noise i immediately turned the car off. Waited again and turned it on same noise.. the only thing I found was a cover under the car towards the front was really loose. ( I haven't hit bottom or anything while driving) but I did have the lighted door sills just installed the other day. But it never made that noise..

btw i have 1100 miles on it..I looked under it and is the black dust protector thing supposed to be loose like if I push on it I can make it rattle..

Passat (B5) :: 2000 - AC Compressor Makes Squealing Noise

All was fine with it until a month or so ago. Now, after the car is first turned on and the AC is turned on, it makes a terrible squealing sound. The moment the AC is turned off it stops. If the AC is left on, it will generally make the noise for a good 20 seconds, stop, and then repeat that a couple more times(and the noise will cease for as long as the car is on).

I popped the hood and took a look (I'm assuming the compressor is on the lower left), and when the AC is off it spins fine. However, when the AC is turned on, the fan starts up, then it visibly stops spinning and really struggles to spin, causing the noise. Do I need a new compressor?

Passat (B5) :: 2000 - Spinning Out Of Control On Turns / CV Makes Clicking Noise Occasionally

It has been raining, finally, in bay area, thats the good part. The scary part is that, today I was driving normal close to 15mph and took a left turn at a traffic light and the car spun out. This was the second time in couple of months. Both times it had rained for long periods, road was not water logged.

First time had spun out of control on right turn and second time on left turn. Tires are close to 30K old. Wheels aligned 6k back, rotated 1k back. And passenger side CV makes clicking noise occasionally. Do not remember, the CV making the noise around the time of spin out on both occasions.

Passat (B5) :: 2000 - Loud Noise Like A Motor Whirring Under The Hood

I have a 2000 VW Passat 1.8T Automatic. During a cold start, I notice a rather loud noise like a motor whirring that lasts for approximately 30 seconds. My RPMs also run about 200 higher than idle during this time. After the 30 secs the noise goes away (sounds like this motor powers down) and the RPMs return to normal.

It doesn't happen every time I start the car, just when it has been sitting for more than 4-5 hours or overnight. What this is and what if anything I should do?

Passat (B5) :: 2000 - Loud Noise Coming From Passenger Side Under The Hood

So I just picked this car up, (2000 20v turbo passat) 93k miles and I did a tune up (plugs, air filter, oil change w/ oil stabilizer, and injector cleaner) when i was out beating on the car a little, afterward I got to a stop sign, and i heard a VERY LOUD noise coming from the passengers side under the hood, it almost sounded like a loud motor, or the turbo but it was too loud to really determine... it was only there for about 10 sec then turned off but came on again about 1 min later. is this a bad bearing in the turbo? or what might it be?

Celica :: Makes Loud Creek / Popping Noise

I recently crashed my celica into a curb and had to replace the ball joint and the lower control arm on the right side. everything went well for a while but now there is a really loud creek/popping noise. it happens whenever i accelerate and come to a stop which led me to believe it was the cv axel going into the differential. but it makes the noise when the car is not running and i push down on the strut. i took it for a suspension inspection but they said they found nothing wrong with it.

Passat (B5) :: 2002 V6 Driver Door Makes Loud Squeak Every Time When Opened

My wife and I bought a 2002 Passat Wagon 4Motion V6 this fall and we really like the car. It recently got very, very cold here and the drivers door makes a loud unlubricated squeak every time we open it. It has warmed up but the squeak remains. What kind of lube to use on the door hinges? Silicon spray or something else?

Lexus RX 2010-15 :: Brake Pedal Makes A Loud Noise

Our 2013 RX350 has a brake pedal that makes a pretty loud noise when it snaps back after you depress it a little harder and take your foot off. I complained to my SA, and they told me it's normal. It's not a big deal, but any other car I have owned, I have never noticed such a thing.

Gmc - Yukonxl :: 2004 - Transmission Makes A Loud Z Noise Only In Overdrive

A friend of mine visited from California and the transmission on his 04' Yukon is making a strange noise that no mechanics can figure out. Prepare for some "sound effects"...........

He said that as he is going down a mountain in high gear, or overdrive, he takes his foot off the pedal and the transmission makes a loud "Zzzzzzzzzzzz" noise. It does not do it in any other gear, only overdrive. Also, it only makes the sound if he is going below 55 MPH.

What may be causing this noise?

Bmw - Z3 :: 1996 - Transmission Makes A Loud Noise When Switching Gears Usually First

I have a 1996 bmw z3 and theres bunch of problems with itone the transmission makes makes a loud noise when switching gears usually first, also you press the gas and it takes couple seconds for the car to accelerate.also when foot is on the brake the car will surge forward or accelerate i was told by bmw that the value cover gasket needs to be replaced cause its leaking oil the air mass meter needs to be replaced i was told by one mechanic this could be why the transmission is having problems or it could be the transmission needs to be replaced ~ any truth to this that the air mass meter could be causing problems with the tranny?? also the os sensor needs to be replaced the check engine light is on....so my question is that could all of these problems be causing transmission issues. There are other problems as well including power issues with the battery, stalling mostly because i havent been driving it also the ac doesnt work but heat does.

Lexus GS 2006-11 :: Brakes Makes Loud Humming Noise When Pressed

2007 GS 350. In the past 6 months i have changed my FRONT brake pads with two different pair. First was a generic pad(REMOVED), and did some research then went for Akebono(CURRENTLY) brake pads 2-months noise-free and now back to braking noise dilemma.

Issues:
-In the morning, first 3-5 pressed brakes makes loud(REALLY LOUD!) humming noise then goes away. Feels like the brakes are rusty but it continually does it everyday. I just got the car serviced so assuming all my fluids are filled.
-Randomly, on a fully stopped brake i hear a whistle noise from the front brake. NOT as loud described above.
-I noticed the noise happened the most on HOT weather, and occasionally on COLD weather.

Longo Lexus advice me to buy an OEM brake pads and should resolve this problem. I'm also thinking of just getting it done at the dealership and pay that extra cash plus warranty.

Prius (2001-03) :: AC Makes Loud Scraping Noise When Driving Down The Road

This is a 2001 Prius - car runs great and the AC is fine. However, driving down the road, when the AC is turned on there is a noticeable scraping/ticking noise - sounds like it coming from under the hood.

With the car parked, and the ignition ON, but without the gas engine running, there is no scraping noise.

Toyota - Camry :: 2000 - Loud Noise And Check Engine Light On

I have a 2000 Toyota Camry with about 136,000 miles on it. Recently because it was making a loud noise and because the check engine light was on we got the exhaust system changed at Coles and this made the car silent as before.The mechanic there checked the check engine light code and reset it and he said it was an Evap code.He checked the fuel cap and found it to be OK. He said that if it comes back again I have to get it checked by some one who has a smoke machine to detect the leak and this could cost me about $100/- to set it right.The check engine light has come back again.

Saturn - Engines - Sl :: 2000 - Loud Knocking Noise From Engine - Tow / Drive?

We have a 2000 Saturn SL2 (120,000 miles). Last night we drove to L.A. and back (from San Diego) , so about 250 miles round trip. For the last 45 miles or so we had the radio on quite loud. At some point in that 30-45 miles the engine developed a very loud knocking noise - like rocks being spun in a tumbler - which we noticed when we got off the free-way and turned down the radio.

This noise did not effect the way the car handled as I did not notice anything when the radio was up. We have been listening to a lot of sounds and I am concerned it could be a Rod Knock - it sounds a lot like this [URL] ... from inside the car, outside it was more of a constant pinging/thunking noise - less gravel sound.

So my quandary is this, our mechanic is not open Sundays so I cannot ask him, but when we take it to him tomorrow, do we drive it or tow it? If the rod is starting to go I do not want to inadvertently do more damage by driving it. The mechanic is 8-10 miles away. We can get their either on the freeway or through surface streets.

Chevrolet - Silverado :: 2000 - Loud Electrical Noise Coming From Engine

So I changed my plugs and wires on my truck a few days ago and now every time I turn my key on a loud electrical noise comes from the engine. I thought it was the front right plug so I changed it. That went great for one day, then the same problem reoccurred. Done this many times never encountered such a problem. It will run obviously weaker than previously. 2000 Chevy Silverado5.3l vortec 4x4136,000 miles....
