Prius (2010-12) :: Whirring Or Buzzing Noise After Shutdown

I have a 2010 IV and after driving for an extended period and then shutting the car off I get a loud noise about a minute or a little more after shutdown. The best I can describe it is that it sounds like someone is dropping a 3 pound dead chicken from about 10 feet up onto my hood. It is consistent and is not any of the whirring or buzzing noises I normally hear. I also have a 2009 Touring and have never heard anything like this.

Prius (2004-09) :: Grinding Sound When Turning Car On And Off Before ICE Starts / Shutdown

Recently (5-6) months my Gen II has been making some weird sound when I turn it on before the ICE starts. Also when I turn it off after the ICE shuts down. I really don't know how to describe the sound so I took some clips of it. Sort of a high pitched grind maybe? Car has 45xxx, just had the Hybrid water pumped replaced.

Prius (2004-09) :: 2006 - Motor Whirring Sound After Turning Off?

We are only one week in to owning our 2006 Prius! Question is why does it sound like a motor whirring sound after turning it off? It only lasts 20 to 30 seconds, just wondering if this is a normal sound?

Prius (2004-09) :: 2005 - Whirring Sound When Take Foot Off The Gas Pedal

I have a "05" Prius problem that I'm stumped on. I have 165k miles. I am the original owner and have maintained this car really well and it really runs incredible. I just started to hear a strange new whirring/winding sound coming from the front when driving. When accelerating it goes quiet. When I let off on the gas it starts whirring. Between 40-45 MPH if I let off on the gas it will whir but then when I drop below 40MPH it does it intermittently. It almost sounds like it is attempting to slow the car down . I've looked over the forum and other sites and hear about other sounds like this (ex: A/C motor), but nothing that matches my symptoms. I can say this, it in no way affects the performance of the car, just very annoying. If it is serious I would like to jump on it right away and try for 200K .

Prius (2004-09) :: Unexplained Whirring / Whining Sound During Deceleration

My "05" Prius has 164K, I'm the original owner and I have had great success with this car. I know some owners talk about the loud whining humming sound from the A/C unit which I am aware of but this newest sound is different and after 4 hours with a Toyota tech all they can come up with is an A/C compressor going bad. I only hear this sound after I reach 40MPH+ and then decelerate. It then winds down with the speed of the car sometime intermittently. If I accelerate it goes quiet.

I've also tried speeding up to 40MPH and then move into neutral. It will stop the noise. I'm adding a video and I realize there is standard road noise but if you watch my energy monitor you will hear the noise whirring winding when the green arrows point back to the electric motor. Pay close attention to the viseo frames at 13 seconds, 22 seconds and again at 29 seconds. Turn up the volume. Of course inside the cab it is much more pronounced. I'm finding it hard to believe this is an A/C compressor. Sounds more like an electric motor whining/whirring. I'm concerned about driving my car for safety reasons.

Prius (2004-09) :: 2008 - Constant Whirring Sound When Engine Is Running

My 2008 Prius has started making a noticeable soft whirring sound whenever the engine is running. You can hear it both inside and outside of the car. The sound lasts exactly 30 seconds, then pauses for 4 seconds, than repeats . When the car is turned off, the sound can be heard for about another 10 minutes before it shuts off entirely.

Prius (2004-09) :: Electric Whirring Sound When AC Compressor Starts Running

I have a 2009 Prius with about 56K miles on it that I absolutely love. Now I know from reading in the forums an my own experience that when the A/C compressor starts running you hear an electric whirring sound. My question is... is it a cause for concern when the sound it makes seems different -- the pitch sounds lower to me now. The A/C still works fine, but I didn't know if this changing sound means the compressor was on the way out.

Prius (2004-09) :: Whirring / Roaring Sound From Front Driver Side

Prius owner. I have 200,000 miles on the car and have done nothing except change the oil, tired and battery. No other maintenance was performed.

While driving straight the front wheel seems to vibrate some and make a whirring/roaring sounds. When turning to the left the noise is greatly reduced. When turning to the right it still exists.

Any potential causes? Possibly the struts? They as well as all the front end components are original.

Prius (Gen 2) :: High Pitched Whining Sound After Shutdown

Yesterday after a 45 minute drive home (GA and above 90 degree heat), I noticed a moderately high pitched whining noise after shutdown. The noise continued for about 5 minutes. From my understanding, the inverter coolant pump redistributes the coolant after shutdown and I have heard a humming noise previously which I assumed to be this action.

Prius (2004-09) :: Noise After Shutdown Occurred For Like 5 - 10 Minutes?

Yesterday my 2008 Prius with 95,000+ developed a new noise after turning it off and it has me a bit worried. I took an audio sample? Last night it occurred for like 5-10 minutes. Now today I went to turn it on and before I even pressed the power button it made another noise that I've never heard before which I didn't get on audio. It turned on fine, I let it run for a few minutes and then shut it off and the noise I got on audio occurred for several minutes. The noise comes from the driver's side by the electric motor. The clip should play in iTunes or Winamp, took it on my iPhone so its kind of low in volume.

Prius (2004-09) :: Started Beeping On Shutdown - Battery Replacement Gone Bad?

2005 Prius, 90k, original battery I think, started beeping on shutdown, then wouldn't start today (cold). Got a new battery, but the back hatch wouldn't open, so I tried to jump it following owner's manual instructions. Headlights came on at first (although stalk switch was off), but doors/car wouldn't respond. Disconnected and reconnected jumpers, lights off this time, still no response when trying doors or starting car.

Prius (2004-09) :: Complete Shutdown While Driving - ECU-IG Fuse Blown

(CORRECTION: AM1 fuse blew, not ECU-IG)
(Correction 2: Update 6/3/2014 AM-2 fuse blew, not ECU-IG)

What caused my shutdown and the ECU-IG fuse to blow while driving normally? I want to get educated prior to the dealer's response.

Prius (Gen 3) :: Low Whirring Sound When Parked In Garage

I parked the little dear in the garage about 9:30 last night. I went into the garage this morning around 6:30 and I noticed how still and quiet it seemed. I then opened the garage door and went outside for a few minutes. When I came back in, I hear a low whirring sound. I went back outside to listen, but it was definitely coming from the Prius, perhaps near the back, underneath.

The hatch was open; I closed it, but the sound didn't change. The fob was in the house, and I didn't open the driver door, so it wasn't the brake pump. It lasted at least 2-3 minutes, at which time I was too bored to continue listening, and I went back to weeding and watering.

Prius (2004-09) :: 2006 - After 5 Minutes Dropped Out Of Drive And Won't Go Back Until Shutdown And Restart

2006 price with going back - rest about 105K miles on it. Recently the dashboard lit up like a Christmas tree with all the warning lights. Battery fan runs non-stop as soon as the car is started and if driven, the gas engine never turns off. When it happened I was circling the neighborhood looking for parking. After about 5 minutes the car dropped out of drive and wouldn't go back in until I shut down and restarted. The battery still charges, and holds a charge when left parked. What is most likely the culprit before I bring it in this afternoon? The dealer is 3.5 miles away (about 15-minute drive in Chicago). Am I risking further damage driving it in? Should I call for a tow?

Update: A check of the inverter coolant reservoir shows that coolant is flowing. Ripples on the surface.

Elantra XD (2001-06) :: 2004 - Making Whirring Sound And Won't Start

I've got a 2004 Elantra, 4 Door Sedan. My wife drove it yesterday and parked it. She later attempted to start it, and it won't start. When she turns the key, the car makes whirring sound like it's about to start up and gets to the point just to where it should turn over, but never does. Lights come on, etc, so it appears it's not a battery issue. We're not super mechanically inclined, but sometimes things like this can be easy fixes.

On another quick note: her car had it's engine light come on a few weeks ago. Took it to the car parts store and read it as a catalytic convertor issue. It went away after she refilled up on gas, so we figured maybe it was some bad gas.

Prius (2010-12) :: Whirring Electrical Sound (at Startup) Getting Frequent

On my 2010 Prius (~75,000 miles): The whirring electric motor sound that one hears when just entering the vehicle (even before starting the vehicle) seems to be getting more frequent (and maybe louder).

I used to notice it only when getting in the car and before or just after pushing in the start button. But now I notice it driving around the neighborhood, even at moderate speeds. Is this a sign of some impending failure?

Prius (2010-12) :: Sudden Whirring Sound From Rear And Accelerator Delay

I have a strange issue that just started happening. A whirring sound comes from the vent in the back seat I believe which sounds like escaping Air. Not like the last 2 years I've owned it. At the same time I noticed that the accelerator now takes a second to engage after I hit the pedal from a stop every time. Furthermore the engine seems to be over revving, as if engine braking. I've restarted the car a few times. I've checked all the fluid levels.
