Prius Plug-in 2012-15 :: Loud, High Pitched Whine Coming From The Parked Car
Nov 18, 2014
Last night around 1:00, I was awakened by a noise I think was coming from my car parked below my window. It was plugged in at the time. I heard a loud, high pitched whine, followed by a couple of knocks or thumps, then a sound like R2D2 makes when he turns his head, then a couple more knocks, and another R2D2 noise. I think I may also have seen lights flashing around the the edges of my blackout blinds, but am not sure, since I had just been sound asleep.

I'm rolling down the freeway in stop and go traffic, so I have been EV stacking. Clicked from EV to HV several times over the course of 5 minutes. Then, I hear this fairly high pitched revving sound - even and constant rev up, not rev/idle/rev. I thought it was the truck next to me, so I turn down the radio and away from the truck but it happened again. I would stomp on the gas for a moment, and it would subside - not completely because it would start doing it again very soon. I'm not accelerating, but it would be like throwing it into neutral and revving. When I come to a complete stop, it would not go to EV - the light isn't on like when it is warming up the ICE.
My exit was coming up soon, so I would alternate pumping the brake and gas to get it to stop. Only when I was at the light that I powered off the car to reboot. Since then, it did not recur. Strange... Perhaps related, but I doubt it - I had bumped into a vehicle around 3-4 mph the day before. I was... drowsy.

I'm going to take my 2012 Camry SE in for service sometime in November and experienced a high-pitched whine (very low volume) in the front end of their car. This sound seems to be coming from the front passenger side of the car and has surfaced only within the last month or so, between 70-75 MPH. Above and below that speed range I hear nothing. This car has low mileage; after almost two years, it has only about 12,500 miles on it.
I'm wondering whether it's a trans-axle whine, but it is of such low volume I don't think it would be easy for a tech to diagnose. Also, other than the D1T recall, are there any other TSBs that I should be aware of, and any recent Entune updates that need to be applied? And, whether Toyota has a remedy for D1T yet?

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)...

My car has 155k miles and I haven't had any previous issues with it. I noticed probably 30k miles ago the beginning of a whine sound when the car accelerates. The noise has been getting louder (it's really not that loud) but I am wondering what this could be. I want to avoid anything happening to the car and want to find out what the problem is so I can fix it.

There's a high pitched whine type noise coming from my Mass Airflow Sensor. I can get it to go away temporarily if I goose the gas pedal, but it comes back after a minute or two. Has not affected drive-ability, but it's pretty annoying. It sounds like the hot wire is probably vibrating. Is there any fix for it, or do I have to replace the sensor to get rid of it?? Have tried cleaning it, but that did not work.

About 3-4 months ago, I noticed a low-pitched "roar" or whine coming from the front of my 07, especially at 35mph and above. The pitch of the sound gets higher the faster I go, but its never a high-pitched squeal or anything, just a roaring whine that has gotten somewhat more noticeable as time has gone on. 184,500 miles on the car, Goodyear Assurance tires that will probably need to be replaced fairly soon but are certainly not bald, reasonable tread left. I bought the car with just under 160K, I've put about 25K miles on the tires, but don't know the car mileage when the tires were originally installed.
I had the tires rotated during an oil change about 6 weeks ago, which made little if any difference in the sound. I asked a mechanic I know (and trust) at the non-dealer where the oil change and tire rotation was done, he said to turn slightly left and right while driving to see if the pitch changes, which may indicate a front bearing problem. There was maybe a slight pitch change in the whine when I did that, if any. He said it might be the start of a bearing problem. I also don't notice any change in the pitch or unusual behavior when making turns.
So is this a tire problem or front/rear bearing issue? I'm going to take it to the mechanic for him to test drive, would I be better served going to a dealer? Given the car mileage, it could very well be a bearing problem, it would certainly be due.

I have been getting a loud, high-pitched mechanical-sounding noise coming from the middle of the dash, near the CD player. It lasts only a few seconds, but it scares the sh!t out of me every time! It happens out of the blue after I've been driving for a few minutes about every 3 weeks or so. The sound is almost impossible to describe...but if you've had it happen you probably know exactly what I'm talking about. It happened today while I was listening to a CD, so I can't imagine it's the player that's doing it. Non-Nav/Air V8

Have a 2010 Prius III (trim V), and a 2012 PIP. The 2010 has a fan that will circulate air when the car is parked. This feature is very useful especially if the car has been sitting in the sun on a hot day like today (and cracking the sunroof).
Got into the PIP today and it was like brick fired oven. Thought to myself maybe the fan was turned off, but unable to locate the button.
Do the outside air circulation fan exists for the PIP.

I bought a new Prius PIP 2012 ten months ago. I park it in the Airport parking lot a day or two when I am out of town. And this is the 3rd time my car is completely discharged.

I had been running on EV then parked in the cold to wait for the wife. Turning on the heater started the ICE (of course). It charged the battery about 0.6% then stopped charging, ICE still running. So I switched to HV and it restarted charging about 0.3% and then stopped charging. So I switched back to EV for a few seconds than back to HV and the charging resumed another 0.3%. Once the coolant temperature reaches 130 degrees the ICE stops. Nice heat until the coolant gets down to 118 degrees and the ICE starts again. Back in EV and the battery is charging and the HV/EV switching continues to add more charge. Until time to leave I picked up about 5% SOC, kept warm. Not good for mpg but 5% SOC is nice.

I have a 2012 golf R with about 25500 miles. I'm getting this high pitch noise coming from the front of the car. I can only hear it with the windows down. It is intermittent, sometimes doesn't show up sometimes there. Gets louder when I turn right. What am I looking at? Wheel bearing? I'm on coilovers.

Had my first drive with the windows down for a long time and noticed a new medium to high pitched whine, stays relative to engine speed. Not the turbo, its much louder than that, i searched about the water pump issues and no one seemed to mention any associated noise, just coolant on the driveway. Waterpump? Alternator?

The vehicle is a 2005 Touareg 4.2 v8 with 81k miles. I purchased from a dealership and have been having nothing but problems from the day I purchased it. (2 months ago) the day after I purchased it check engine light came on, headlight range light, air bag light, and now this noise I have owned about 15 vag cars and also own vagcom no codes pertaining to this noise... Above 10-15mph there is an intermittent whine (high pitched) for the most part the noise is there most of the time.
It does not stop when in neutral not effected when the air is off or on, does not change if you down shift, no change if the wheels are turned. I broke down and took it to a very trustworthy Audi shop in the area and you guessed it the entire way there no noise... The tech drove it no noise so I had them flush and fill the trans as it was due for it anyways. They informed me that it was dirty and I figured that it may have taken care of it. Well after a 20 minute drive home the noise started again! I took a short video....

I recently noticed that my Golf R was making a strange high pitched whine and it seemed like there was no boost. I took my car to the dealer, and it turns out that part of the CAI broke off (a mounting component) and made its way into the turbo, effectively destroying it.
My dealer was initially intending to cover the turbo under warranty (prior to investigation), but now that it is clear that a failure in the CAI caused the issue, they cannot (obviously) cover it under VW warranty. Unitronic CAI failure led to turbo failure.
The serviced manager did some research prior to getting back with me, and was somewhat puzzled since the Unitronic CAI displayed on their website looked slightly different from mine in that the component that failed was not there. The service manager called Unitronic and learned that the failed component was a known issue (it had apparently failed before), and thus they modified the design - hence the picture of the revised version did not match the older version that was installed on my Golf R. The Unitronic rep offered to replace the CAI - but did not mention anything about the failed turbo (when he spoke to the service manager).
I found the following thread which illustrates that this was a known issue: [URL] .... I just wish I had found out about this before it failed.

My 2009 Camry with 72k on it has started to make an intermittent high pitched whine from the rear of the car. It's only noticeable while accelerating or maintaining speed.

Just had 4 new rotors put on my '08 LWB after 70k miles. A few days later, I noticed a very high pitched whine that occurs occasionally at speed. When I brake, it stops, and it restarts a few minutes later. It almost sounds like what you detect during a hearing test, only louder. And before you ask, passengers can hear it too.

Car was in the garage. Had been off for hours. Husband noticed a high pitched whine coming from the rear of the car. Louder underneath. I opened the trunk and took out everything in the cargo net (thought something had gotten stuck in it, a gadget of some kind). Nothing there. I went to unhook the net and pull up the mat etc. and the noise stopped (coincidence I'm sure). I couldn't find anything. It didn't sound like it was coming from the wing at all (had trouble with wing being stuck down when I first got it).

This 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.

I noticed when I first start of my 2006 Azera at night or even during the day and make the first turn of of my driveway or out of the parking lot at work there is a high pitched whining sound. Sounds like it maybe coming from under the car maybe from the back. I thought at first it maybe a belt (power steering) under the hood but it sounds like it coming from the back side of the car. It only does it one time mostly when its cold outside. What can it be?
