I had a rebuilt alternator installed on Thursday and for the past two days when I start up the car there is a high pitch whine coming from what I believe is the alternator. Do some rebuilt alternators make noise when charging the batter after start-up? The alternator has a 3-year warranty and I'm going back to the shop tomorrow.

View 8 RepliesI've got a 2006 Prius - yesterday afternoon my wife and I noticed a high pitched whine coming from the front (maybe right hand side) of the car - we don't hear it until we reach about 50mph. It gets louder as we increase speed and then trails off when you step off the accelerator and can't hear it all below 48-45mph.
We bought the car new and are familiar with the various noises the car makes, but this one is new - never heard it before yesterday.
During around town driving I am experiencing a faint high pitch whine when braking. This sound is not mechanical, but more electrical coming from the dash-engine area. It is very noticeable when slowing between 40 mph to 20mph.
View 3 RepliesI just bought a 2007 es350 yesterday with 67k miles. When I test drove the car, the highway was too congested to get the car above 50 mph. So, the car sounded fine to me and I purchased it with a free 90 day, 3k mile powertrain/engine/transmission warranty. The car should still be under its standard 7 year 70k mile warranty as well, right?
Fast forward to today. The highway was less congested and I was able to get the car up to 80 mph. However, I noticed a constant hum start at 60 mph, which became louder and more high pitch at 75 mph. I am taking this back to the Lexus dealership from where I purchased it to get the sound diagnosed and repaired. I'm hoping it's a problem still covered by the warranty, like the differential (does the ES350 have a differential since it's fwd) or pinion bearings. Could it be something simple, like a bad tire?
When I'm driving at a certain speed (usually between 65-70 mph), my 06 Sonata GLS V6 develops a really soft (but really annoying) high-pitched whine that decreases when you take your foot off the gas. Not much at other speeds (sometimes it will kick in real quick at high rpm before the automatic trans shifts), but when the car hits 66-67 mph that little subtle whine kicks in. By 75 mph, it's gone (I drive 75+). Sounds just like a high-pitched dog whistle.
Not a wind noise....sometimes it sounds like it comes from below me, sometimes it sounds like it's coming from the dash. Dealer don't hear anything (of course), even when I'm in the car with the tech and can hear it (maybe I'm part dog.....who knows).
Here's my guess.......I think that it's the electric fuel pump. Sometimes if I'm outside the car, I'll hear a whine back in the fuel area that is almost the same pitch as the whine I hear at 70. Since the whine varies (or disappears) with engine rpm and application of the gas pedal, my thought is that I'm hearing the fuel pump hit a certain pitch, which causes the whine.
2006 Sonata?
I've got a 2006 Prius - bought new in 2006. Yesterday I started to hear a high pitched whine or hum from what sounds like the front right side of the car. I hear it when the car reaches about 48-50 mph and seems to increase as you go faster. Once I let off the accelerator the sound slowly goes away. I know there are a lot of noises from the Prius, but this is one I've not heard before.
View 2 RepliesI have an 03 2.0 jetta manual shifter. Never had issues before this morning. Got in car and sounded like it wanted to turn but wouldnt turn over. After a few attempts the turning sound stopped and I heard an electric pop. Now engine won't even try turning when I turn key it just clicks and engine makes a high pitch noise. Took starter and battery out got both tested and they are fine...
View 3 RepliesOur 2008 Honda CR-V w/120k one owner, always dealer maintained, vehicle has recently started exhibiting a little high pitch whine coming from the engine area which increases when you rev the gas. I checked the transmission dipstick and the level is just below the bottom hole (owners manual says it should be between the bottom and top hole). Would this make the whine? By adding some fluid should it go away? Is it okay to use a fluid other than Honda's?
View 3 RepliesI own a 2002 Jetta 1.8T now here is my story.
A week ago whiles driving lost power when accelerating, EPC light illuminates so I turned on my hazard light and limped home since I was far away from home. As I limped home, all the lights on the dash went off. I got home, shut engine off, restarted the car but car wont accelerate.
I popped the hood and saw the dreaded melted fuse box on top of battery with charred alternator cable. I ordered the fuse box and alternator cable and prepared to replace them.
I realized that with the driver side door open with no key in ignition, I could hear a clicking sound with inside lights blinking. Didn't worry because I believed it had to do with the melted fuse box and charred alternator cable. I noticed that the clock was off too.
I replaced.the fuse box and alternator cable. My battery is just a year old so when I tried starting the car and it won't crank, I tried to jump start it but no sound. Car won't start. Dead silence,no click nothing.
2002 Ford Ranger 6 cylinder Manuel Drive, whenever you push on the accelerator makes a high pitch squeal. Changed Idler pulley and belt, No luck.
View 3 RepliesI have a 1995 Lexus ES300 with 130,000 miles on it. When I reverse, I get a low-pitch growling and as as soon as I apply the brakes by a high-pitch, ungodly screech. This noise is definitely coming from the rear wheel areas. I'm not sure which tire is the culprit (I hear both sides from while listening from both the inside and outside). It happens frequently but is particularly bad on rainy, snowy, misty, or high humidity days. Two years ago I replaced the pads and rotors. At this point, the pads look to have about 40% life on them yet. This problem started happening about a year ago.
My initial thoughts were that it was just rusting because of the frequency on high moisture days. But both noises are way too loud for that. My second speculation was that the emergency brake was catching, but after examining it I think not. I've taken the entire assembly (brakes, rotors calipers, and emergency brake) at each tire apart and looked for any obvious issues that look incorrect. No luck. I've also applied brake quiet with similar results. Now my thoughts are that the low pitch is the rotors being warped. But that doesn't explain the screech and why it only occurs in reverse.
I bought a 2002 accord with 105800 miles 3 weeks ago. I got the timing belt and water pump replaced within a week of that. I have noticed that the car makes a high pitch noise upon accelerating after replacing the belt. It does not happen always, but sometimes. I have noticed it on 3 days in last 2 weeks. A preliminary web search tells me that it could be a tight timing belt.
View 3 RepliesIs it common for the exhaust to have a periodic high pitch tinny sound?
View 4 RepliesThis has begun in the last few weeks on my '02 SF (which only has a couple of months left until it is retired )....
If I'm going anywhere between about 90-110 KM, I'll hear an odd high pitched whine. It sounds almost like microphone feedback, and I'm having a really hard time trying to find out where the sound is coming from. It is very subtle and comes and goes.
My friend and I both have the MK4 R32. He had a bunch of stuff replaced in the engine. (a bunch of plastic parts that are super expense, the timing chain, something related to the guide, basically the plastics that holds the engine cushion/absorb) Anyways, his engine sounds great and quiet at the same time with a little high pitch noise when the RPM is hanging in between 1K and 2K.
Our cars were in the garage and I did the same thing and it sounded NOT quiet, a lot more noise than his. There was an obvious difference in noise coming from the engine with the hood open. I do have cams and a light weight pulley. Can that have an affect on the engine noise? If I am not making sense, then i should probably video record the sound or take it to the dealership for a check up. Also, I am at 93K.
I don't own a VW, but my friend does, and she knows absolutely nothing about cars. She drove me home from a friend's house today, and I noticed her car was sitting at insanely high RPMs, even though we were only going like 60-65. The car was ranging from like 4500-5200rpms the entire way home, and the engine sounded like a lawn mower.
Don't know many details on the exact model of 2002 jetta it is (I'm a subaru guy) but it's an Auto. I was convinced she had it in 3rd the entire way instead of drive. I asked and she said it was in drive, but I was sitting in the back so I couldn't quite tell. Not sure how being in 3rd works on an automatic, but she could still come to a full stop. The car was pretty much constantly sitting at above 3k whenever it wasn't at a full stop though. Like, after letting of the brake at a stop light, and pressing the gas, it'd pretty much immediately flick up to 3k and never go below.
So, not sure if this is normal for these cars, but I thought it'd be worth asking since it would suck for her if this could have been fixed earlier. My subaru sits at 3k when I hit 60, and only hits 4k if I'm going like 80, so I just thought this seemed pretty weird.
The symptoms are as follows.
-No change in performance, functionality, or spooling.
-Loud intermittent screeching noise when building boost above 3500 RPM
-Can only describe the sound as air escaping from a tiny hole, VERY similar to warn brakes, that kind of screech. The intermittent part I would describe as if you were tapping your brakes (and they were screeching) rapidly, so on off on off very quickly.
-Also happens when I let my foot off the gas (Also above 3500 RPM)
-Car has CTS Turbo Intake, 42DD Downpipe, and APR stage 2 software.
I have the most annoying high-pitched squeak/whine coming from my front left tire. For those who cant see the video, its making a high pitched, metal on metal noise... at all speeds... especially when making slight turns... my foot was not on the brake when the video was taken (coasting around the parking lot at around 10 mph)...

View 16 RepliesMy first VW was a 2001 4-door Golf (Silver), traded to 2003 GTI (Silverstone), traded to 2006 Jetta Wagon (Blue). Then the wagon was traded for a SUV. Well last week, I have decided to pick up my 4th VW. It's a 2012 CSG 4-door GTI.
After driving the car for a week, and putting on 350 miles, I heard a high pitch continous "whistling" sound from the engine. Took the car to the dealer this afternoon. Tech came out and loosened the coolant reservoir. I heard a "pooof", sound of air build up. The tech said VW is aware of this problem. Something to do with the water pump bearing. It has to be replaced. They took the car in to replace the water pump.
