Prius (2004-09) :: 2008 - High Pitched Woo-woo Noise During Acceleration
Mar 6, 2015
I took my 2008, 56k in for a new battery after my car sat outside in negative degree temps for a few days. After doing that repair, the dealer recommended a new serpentine belt. Ever since that service appointment, the car is making a high-pitched "woo-wooo" noise during acceleration. It's definitely a noise I've never heard before. I took it back to the dealer two days later; he had the service guy drive it and they both claim the noise is normal and just due to the cold. Is it the belt? Is it the cold? Am I losing my mind?

I know this noise is the Thermos Pump and it operates when I turn the car on and off. Question - is it failing - also a really annoying noise, but I'll put up with it as long as nothing's breaking.

When it is cold (below 30 degrees) and above about 30mph, there is a loud high pitched squeal (rather like the pitch of a squealing hearing aide)that seems to come form the front drivers side. The colder it is, the louder it is.
When I am able to take it in it is too warm to hear it. What might be causing the noise and will they be able to figure it out if it isn't making the sound?

I have a 2008 Santa Fe LTD, and just recently started experiencing a strange noise when I am accelerating, and I cannot pinpoint it. Here is some info on the noise.
-2008 Santa Fe LTD AWD, about 25,000 miles
-Sounds like a little higher pitched hum, not very loud
-Seems to be coming from somewhere near the passenger side backseat area (first found out about it when someone was sitting there and asked what the noise was)
-Cannot tell whether it is coming from the interior or exterior of the car, but I think exterior, but it is definitely somewhere along the passenger side, from the back half of the car.
-Noise occurs when accelerating from a stopped position, only when accelerating, never when braking or idle.
-Noise occurs only when car is in gear (hitting the gas pedal in park does not cause the noise to happen)
-Noise doesn't occur at high speeds or when accelerating at high speeds
-Noise only really occurs for a 2-3 seconds while accelerating, then seems to go away as I continue to drive.
-Noise doesn't seem to always happen, but very frequently.

I have an '08 Infiniti EX35. When my foot is on the gas pedal, I hear a subtle, but high-pitched ringing noise. It sounds electrical like the noise a tv would make. It's not coming from the engine. It's very annoying and only happens with the foot on the gas.

I just bought a 2006 F150 SuperCrew with a 5.4L engine and since the weather has turned cold, I've noticed an intermittent high pitched squeal coming from the engine compartment. I've replaced the serpentine belt and the idler pulley plus another belt pulley but none of the above worked.
I've also had two separate mechanics look at the problem and both are at a loss as to what could be causing the noise. The guess is maybe its an air leak coming from either the intake or vacuum lines. But nobody is really sure.
The noise seems to really become noticeable when the temperature gets below 20 degrees and around 2000 rpms, but sometimes it happens at other times. Where this extremely annoying sound might be coming from?

Usually after I run the car in manual/sport mode, I begin to hear a high-pitched 'hissing/whistling' noise coming from the engine. It sounds like a vacuum leak. It is audible while driving with the windows down.
I am having problems pin pointing the source, but it sounds like its coming from the center block. What is the right direction to the leak? It starts exactly at 1500 and cuts off at 2200 rpm (while in gear). 1500 to 3000 rpm while in park..
I have a Takeda intake installed and I re-tighten the fittings.

My truck started making this whistling sound a few thousand miles ago. Its a high pitched squeal coming from somewhere under the hood. There doesn't seem to be any pattern or certain time when it does it. Ive read on here about an alternator problem on these trucks. Or could it be my S&B intake?

I have a high pitched squeal coming from the back windows during operation. I am pretty confident it's not the window assembly itself (linkage, track, etc in the door), but rather the weatherstripping type material that physically lays against the glass at the bottom of the window opening on the door. This happens in both up and down directions of the window.
It DOES NOT squeal when the material is wet, and thus is the reason that I've been able to pinpoint the cause. It's likely that the window channels could be contributing to this as well. The problem is...I don't know how to solve this without applying a lubricant that will smear/streak my windows.
I've already taken clean rags and wiped both the inner and outer portions of this material to remove dirt and dust that they gather...no change in the noise. Is there a way to "condition" the material so they will soften up, without leaving a residue that will streak the window?

I've noticed more and more that when I am braking that I heard a high pitched whining noise. Sort of this ultrasonic type sound. It will only go away if I depress the brake pedal very firmly after being completely stopped. However every so often the firm press will not stop the noise. I hear it more in the evening on the way home than in the morning to work, though I may not be paying attention as much in the A.M. due to morning brain fog.
I don't hear it any other time. I'm worried something is wrong with my inverter.

My '04 started making a high pitched noise from the right front wheel within the last two weeks. It's in the local dealer now and they tell me they suspect a bad right front wheel bearing. I don't see any posts about similar experiences here. I kind of worry that the fact the vehicle is two years old and only has 9200 miles on it may be part of the problem-is infrequent use enough to cause the bad bearings? I drove it infrequently (1-2x/week, sometimes no driving for a week or two) up until the last three months, and now it's being driven daily.

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.

Car suddenly started a high pitched whistling noise/metal on metal sound at highway speeds. It is intermittent, no noticeable pattern w/acceleration or braking. Similar sound at lower volume when the shock/spring is depressed (pushing down on that corner of the car). Louder at low speeds.

About a month ago, I purchased my 2013 Prius Four. I've put on about 2,500 miles so far and recently started noticing when I start the car up, it is giving off a high pitched squeaking noise. This happens both when the car is using the electric battery and when I can feel the gas engine kick in. After about a minute or two, the noise goes away and doesn't come back.

I'm completely new to hybrids. I have a 2001 Toyota Prius with 146k miles and its been running very good until some weird things started happening during the past couple of months. When I start it up, the brake light and abs light come on along with a steady high-pitched noise and grinding noise (sounds like ice being scraped). While the lights are on and the sounds are being made, the brake becomes very soft/"spongy" and goes down to the ground without much force at all (It usually always does this when I start it up and sometimes - but not very often - when I'm driving). Sometimes it all goes off and everything is normal again after about 10 mins, sometimes all day, and sometimes only after a minute or two (It usually does it on a cold start, but sometimes even if the engine is heated up, it does it).

I have had my certified 2010 Prius II, not two because it is a 2010 and 2010 used uppercase roman numerals for model designation, with 82000 miles about 3 months and sometimes when I apply the brakes I hear a high pitched whirring noise. I think the closest thing to compare it to would be a skill saw but not that loud.

Yesterday as soon as I started my car, I noticed a high pitched whining noise. As I drove, it seemed to stop, but as I slowed down and idled, it came back. After driving a couple miles, the battery light came on, so I turned off the AC, radio, and lights and it went off again, but as I sat at stop lights it would flicker on and off again.

2004 Passat 1.8T Tip GLS FWD ... Stock wheels w/ Dunlop Sport SP5000 tires ...
A high pitched chirping noise comes from the front passenger side wheel ONLY when turning left and ONLY when it's below 40F. Goes away once it warms up.
Wheel bearing?

I have a 2004 Honda Element and when the AC compressor cycles on it makes a high pitched noise similar to a drive belt slipping. The AC is still cold and the noise is not overwhelming (yet). I know this vehicle has a serpentine belt and that doesn't appear to be making any noise. The only noise is when the compressor is running.
Is there a belt that drives the compressor (other than the serpentine)? And, is this something that I should get fixed ASAP or can it wait until my next oil change? Meaning, if I wait until the oil change (under 1,800 miles) will hurt anything?
