My 2005 Prius with 170k miles started making a whining noise after the car is warmed up. It is noticeable from about 30 mph, but mostly at higher speeds. When you take your foot off the accelerator the whining stops. It has gotten a bit louder over the past several weeks. I took it to a Toyota dealership and they want to replace the transmission because they believe it is a failure of the transmission's 2nd stage.
View 3 RepliesSo I started getting this metallic/harmonic whining sound from my GTI's engine a few weeks ago. It was barely noticeable then, but has now gotten louder and more consistent. The sound occurs once the engine has warmed up and can be reproduced by holding the revs constant anywhere above 2k. The sound does not change in pitch with engine speed. It doesn't matter if the car is parked or moving.
I've attached a video... The sound can heard starting at 00:23 and becomes constant after a few seconds. Its hard to hear at first, but if you listen carefully its definitely there.
I have an appointment with the dealer tomorrow and will update with their findings. In the meantime, any clue as to what this could be? I can't really pinpoint where its coming from, seems loudest near where the oil filter is? By the way I'm 100% stock.
I stuck my phone down by the electric motor and recorded this while the car was running:
My '06 has been making this odd noise coming from the front of the vehicle. It's coming from somewhere under the hood on the right side (the driver's side), and I think it's under or next to the electric motor.
It happens when warmed up, and only when the vehicle is turned on. It doesn't seem to be related to the ICE, because the noise happens regardless if the ICE is running or not. In fact it happens rarely, so when I heard it I jumped out and tried to locate it (and recorded it with my phone).
Just picked up a 05 with 99500 on it. Drives fantastic and previous to this I used to have an 05 way back that I drove new to 64k. Anyway I test drove it in the rain and with chatter between my wife and I with the sales rep I didn't notice it but now I found that there is a whining noise coming from the timing chain area of the motor. Its only when the car is on and it gets louder as you go towards the passenger side and away from the hybrid components. Here is the sound from my iphone near the motor.
View 3 RepliesThere is a whining noise related to vehicle speed and is most noticeable under the lightest acceleration at 40-50km/h, e.g., keeping a constant speed on the flat. It basically goes away on harder acceleration and is not there when decelerating. All other noise is as expected and not intrusive or unusual. Car is 2005 with 212k kms.
I changed the ATS fluid recently and didn't notice any metal "glitter" in the old fluid or much stuff on the magnet . It was just a mm of black sludgy stuff that didn't seem metallic. The fluid that came out was dark as I assume it hasn't been changed before no chunky globs or anything that would spell trouble..
What is causing this? The car is great other than this annoying noise which happens to be at speeds you normally do around town...
Over the past 2 weeks, started having a whining noise from front end. It seems to be coming from the front passenger side. The noise starts at around 30 mph and increases with speed. Very noticeable at highway speed. Sounded a bit like tire noise. I did rotate the tires, front to back, but noise persists from the front.
View 6 RepliesDeveloped a whining type noise in my '07 prius engine compartment. Noise only there when gas pedal pressed. If I let off on gas the whining noise stops.
View 9 RepliesI'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.
I began hearing a whining/humming sound just a couple of days ago esp when hitting 45mph and then would notice as I took my foot off of gas. I had hoped it was either tire or bearing related, but Toyota tried for over an hour and finally determined it was transmission related..a new transaxle assy etc would cost a total of 6500$. However, they said they did not think I had to do anything right now as everything is well lubricated..they even thought it could remain the way it is for a year to two. My Prius has 180,000miles on it. Should I attempt to find a salvage transaxle and risk having it put in? Or should I cut my losses and given up?
View 1 RepliesSo I have had my 2005 Prius for over a year now. I love my car but after 7 months it made a whining noise coming from by the pulley. When I would accelerate the noise would get worse. Engine light came on tested and said loss of power. The car would not go up large hills it was gutless. So I parked it. I recently just replaced the pulley and now the noise is gone. I have been driving it short distances and at about 30 miles per hour the car would sputter and hesitate. I would let off the gas and push down on gas pedal lighter and it would go fine.
View 19 RepliesI have a 2005 Prius, purchased 5 months ago with 100k miles, and it currently has 106,000 miles.
The air conditioning blows cool, but not cold. When the A/C is turned on, it makes an unpleasant whining noise. I have a recording of it.
It did not make this noise 5 months ago, and the A/C output was colder then. I haven't used the A/C that much over the winter, but it's starting to warm up now and I've noticed it's not doing as well as it used to, and it isn't sounding very good either.
My 12 volt battery is flat. I attached my CTEK MXS 5.0 and started on the Normal setting. I figured (wrongly it seems) that having the battery charger attached would support in starting the car. The green light displayed when I depressed the brake pedal and I pressed the Start button, but everything went dim and the brake pump slowly wound into life. The Start button glowed was on but no other functions started.
I pressed Start again and the light went out. Now when I connect the battery charger, a whining noise starts from near the inverter. The speed varies; dropping from a peak and rising again, and there's probably a pattern to it.
I've disconnected the charger a few times and the noise stops immediately. I wonder if the car has not switched itself off. I've disconnected the charger and I'm waiting some period of time before connecting it again to see if something will fall asleep. If not, I'll just have to climb over the back and disconnect the battery from the car before I charge it.
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.
View 4 RepliesStarted the car the other day and a loud whining noise followed by the car "jumping" when I stepped on the gas. It would go/stop for a second, then shut down. Mechanic who is not a Prius expert said it was the tranny. He could put in a used one (77k miles). Car has 250k miles on it. Is it worth it? Or should I just part it out. I'm worried about things like the battery going next.
View 8 RepliesI need to diagnose an issue I've had with my 2007 Prius with 79,000 miles on it. Several months ago I noticed a distinctive whining/humming noise coming somewhere from the engine compartment of the car while driving. The noise may be present at lower speeds, but the volume of the noise appears to increase proportionately with my acceleration and as such is most noticeable at highway speeds of 50 - 70 miles per hour. As I accelerate faster, the noise level seems to increase. If I take my foot off the gas and coast, decreasing speed, the whining noise gets lower in volume. I believe I first noticed this noise about 6 months ago, but wasn't more proactive about it like I normally would be because at first the noise didn't seem overly loud and my extended warranty unfortunately was up once I hit 77,000 miles. Now 6 months after I first noticed the noise, I believe it's definitely louder than it was when I first heard it, so much so that I can pick it out over the radio being on at a decent volume.
After checking some forums I thought the culprit might be a wheel bearing. I took it into a local Midas shop at they informed me that my passenger-side front wheel bearing was actually breaking apart in pieces. Obviously I had that wheel bearing replaced but I was also hoping this was the source of the whining noise. Unfortunately that wasn't the case as driving it home the noise was still present. They also said the tires were not balanced properly (from my Toyota Dealership no less when I had them install new tires) so I had the tires rebalanced as well. They did take the car for a test drive but probably stop looking for issues with the car as soon as they saw the wheel bearing in that condition. Also that shop does not specialize in Prius' or hybrids so they might not be able to notice the noise that shouldn't be there like I can.
Other than wheel bearings, where this noise could be coming from. Some posts on here possibly pointed to the ICE water pump or transaxle fluid (which as far as I know has never been replaced since I bought the car new).
My 1993 Geo Prizm (with 275,000 miles on it) makes an awful high pitched screeching noise when I first start my car in the morning. The noise goes away once I am in second or third gear and is completely gone when my car is warmed up. It used to just happen in the winter and now it also happens during the summer. I had all my belts replaced maybe 6 years ago. Is this a problem of loose belts or bad power steering pump. Looking at the pump when I'm turning the wheel it seems as though the power steering pump belt stops turning. I also have crunching noises comes from, I think, my wheels when I turn sharply. What could this noise be? Time for a new car??!!!
View 11 RepliesJust got my 2013 CPO GS350 and love it. I did notice this morning a tapping or ticking noise, like a diesel engine would make, as the car warmed up. Anything to be concerned about or can that be normal for a GS? Also, are there any recalls or TSBs I should check into for this car?
View 14 RepliesRecently noticed a hissing noise coming from the passenger front-side of the engine compartment (alternator area). The noise only appears when the car is warmed up and revved to over 2k rpm. At that point the hissing starts and does not stop even when idling. As soon as the engine is turned off (even when warm) and re-started the noise is gone (until 2k rpms).
View 2 RepliesI own a 2007 Sonata 2.4l GLS with 120,500miles on it. In the past three weeks (recently after oil change) its developed a clunking noise only when warmed up (about 40 seconds). I purchased this car beginning of August and it had no noise then. I changed the oil with 10w30 castrol hm oil (the dealer I bought it from stated they put in same viscosity although oil cap reads 5w20 manual says 5w30 is acceptable) . Ive had it checked out by mechanics who have no clue what it is and want to tear down the engine. The noise goes away if it revs a bit higher that 1200rpm and then cones back worse when revving down until idle where its not as bad again. I've changed spark plugs (they were factory anyways) and ran premium fuel and even bought a Hyundai filter afterwards hoping it would work but to no avail. I have a video sound clip where its clearly audible Sonata Ticking Noise - YouTube .
View 18 RepliesWhat is this noise? Video included... [URL]... This noise comes up after the engine gets warmed up and only when the car is decelerating or idle. That is, as soon as I take my foot of the gas pedal the car starts making this noise and it is very loud. No error codes.
View 3 RepliesToday my Prius surprised me. I drove it out of the garage and it had 2 bars charge. After a few secs, as usual, it fired the ICE. Ambient temp was 21C/70F. The ICE stopped after only 1 min as per 1-min fuel consumption screen. Maybe it was a bit longer (more than 1 but surely less than 2) - it never warmed up that fast after a full night cooling off.
