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) :: Front Wheels Chatter With Clicking Sound On Any Sudden Bumps
I have been driving 2013 model for five months. I noticed that whenever any front wheel rolls over cat-eye on the road and any sudden small bump then it generates noticeable clicking sound. I went to the dealer and they said it is normal and comes with all such cars.

For the past day and a half, when i start my car there isn't the usual smooth, quiet sound of the engine starting. There's a slight delay, and a whirring noise. When i put the car into gear and accelerate, the noise increases in volume and pitch. I think it might be something with the power steering pump or a belt issue, but I'm not fluent in Car and Driver speak.

What may cause a strange whirring sound when my R32 is on. I can be in park, sitting still..whatever...It sounds like it's coming from somewhere around the rear tires.
Whirring...humming... Honestly to me it sounds similar to an electric motor trying to do it's job but something is keeping it from doing so. Would be the best way to describe it. I just got the car a few weeks ago and the sound started last week.
Golf V R32 :: Pretty Prominent Whirring Sound Coming From Rear Passenger Area
Noisy Fuel Pump ??? At least that's what I think it is. Pretty prominent whirring going on, sounds like it's coming from the rear passenger area. Dealer listened to it, agreed something was up. No immediate answer, will have to schedule service.
View 4 RepliesFord Excursion :: 2000 - Whirring Sound From Rear And Rough Running When Rainy
I have two issues with my 2000 6.8L gas excursion. Neither seem to be causing any harm...
1st issue - While its raining, or even just really humid, on a cold startup, my truck runs rough. it almost feels like it wants to die, but doesn't. After about a 1000 feet down the road, it runs normal.
2nd issue - I've started noticing that almost always, I here a whirring type of sound coming from the back. It is not from the brakes, as they are new and the sound is best heard at a complete stop. The sound lasts for about 3 seconds and then repeats after a few more seconds. At first I thought it was the coolant circulating through the pipes that run to the rear heater unit, since the sound sounds a lot like fluid flowing through a pipe. However, my coolant level is normal and the system is tight and I have not had to add any since the only major overhaul in January. At idle, the engine sounds like it isn't idling at a constant rpm, but more like a slight up and down in rpm, but the amount is so slight, it doesn't register on the tach. The only other thing that comes to mind is the fuel pump. Is this sound a sound of imminent failure of the fuel pump? Or is it normal? The truck otherwise runs great at any speed and pulls my boat as well as I would expect it to.
Lexus SC430 :: 2005 - Sudden Whirring At Idle
I hope I didn't just happen to notice this today if it has been going on for any length of time now. I started up our '05 this morning and she's definitely whirring at idle. I do not recall hearing this sound at all recently and we've been on a couple lengthy trips with it. Fluid levels all appear normal.
Had my wife start it up too and she agreed that the whirring was not there previously. What are the most likely candidates into which I should look first? It' not high pitched, but a steady muted whir of the type I might expect to hear when two gears spin while making contact.
Santa Fe (CM - 2007-12) :: 2010 - Loud Whirring Sound After Engine Turned Off

My car developed an "intermittent" accelerator whistling noise coming thru one of the speakers (I think). The harder you accelerate - the louder the whistle. When idling, it sounds like an open air whirring noise. Of course every time I bring it to the shop - it stops and when I hear it it's never convenient to get to the shop!
View 4 RepliesPrius (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) :: No Whirring Sound After Shutdown
I have a concern about not hearing the whirring sound after shutdown anymore. I know that the sound comes from a small electric-pump that pumps 3 liters of coolant into a thermal container (to keep it hot) everytime I turn the hybrid system power OFF. When the power is turned back ON, the coolant is pumped back into the engine.
I've noticed that after I got an oil change and tire rotation at Pep Boys the sound is no longer there after shutdown or power up. Then after a couple of days I took the car to the dealer to fix the tire rotation (because Pep Boys didn't do a good job at rotating the tires, there was a woo woo woo sound while driving) and the dealer also did a multi-point check, but they didn't say anything was wrong with the car.
Prius (Gen 3) :: 2010 - Hum Sound Coming From Rear After Car Hit While Parked
My 2010 Prius was hit while parked. The left side was wiped out and the whole car was pushed sideways about 2-3 inches, with the parking brake on. Toyota checked out the car and said everything looked fine. But there is this odd sounding humm coming from the rear of the car. Toyota says that is normal. Is this true?
View 1 RepliesPrius (2010-12) :: Sound From Rear Wheels When Jacking Up
Yesterday when I jacked up my car to switch to winter tires I hear this clicking sound, every stroke I turned the jack it will make that sound and it continues until my wheel is off the ground then it will stop. It only came from the rear 2 wheels and it happened when I jacked up the front and the back (more noticeable when jacking up the back).
I continue anyway, but today when I am driving down a parking lot (down hill turning) I hear this bumping sound from the back (sounds like bouncing basketball), it will go away if I stop but continues once I start driving again. I stop the car on flat ground and examined the tires and found nothing odd. Then when I restart the car the sound went away.

View 4 RepliesPrius (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 .

View 6 RepliesPrius (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 (2010-12) :: Fan Sound At Passenger Side Rear Of Car After Being Parked
We have a 2010 Prius Type 5 with about 18K miles. I've noticed at times that after having parked the car in the garage for several hours, that there is a soft "whirring" sound on the passenger side rear of the car. I'm assuming this is the battery fan, because it sounds like a fan and I can't think of anything else back there that would make a "fan"-like sound? Is there any other device back there that could make a "fan"-like sound while parked (it's cold weather here, so it's probably around 40 deg. F or less in the garage)? It makes this noise for 5-10 min. and then stops. If this is the battery fan, why would it run when the car is cold?
