This is strange. Twice in the past week I have gone in my garage at night, and my Prius'10 is make a buzzing whirring noise. Without touching it ... it's just sitting there making a buzzing noise. This is hours after using the car.
View 19 RepliesI 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.
View 3 RepliesMy girlfriend just picked up a 2007 Prius Touring, 78,000 miles, original owner. It was a private sale and I took a look at it for her. I'm just learning about the Prius and stuff to look for, but everything looked good on it to me. After purchasing it she noticed a noise coming from the drivers side dash. I searched here and saw that dash rattles are common, but this sounds more like an electric buzzing/whirring noise. The duration of the noise is always about 2 to 3 seconds in length, then it stops. There doesn't seem to be any common factor for when it occurs. Is there anything electric on the drives side dash (far left side, closest to the window), that might be making this noise? It's not super loud, you can't hear it if the radio is on.
View 4 RepliesMy new 2013 prius c engine makes buzzing, whirring, clicking noises, especially when speeding up or slowing down. Why?
View 4 RepliesI have a 1993 E350 Econoline-based RV. The blower motor intermittently makes a horrible whirring/buzzing sound, usually if on position 3 or 4 (high). Doesn't stop until I turn the HVAC to Off. The blower motor vibrates quite a bit while making this noise (verified with my hand). The problem occurs even if the engine isn't running. This started a few years ago, and has simply gotten worse.
Since it runs OK at the lower speeds (until the problems start with the higher speeds), I think that means I can rule out something simple like debris? Also, when the engine is under load (climbing hills, etc.), the blower fan cuts out. Could that be a resistor problem, or something else?
For about a year and a half I have had an "undiagnosable" noise that started as an intermittent metallic buzzing and has evolved into a constant whirring/grinding noise. The tempo of the noise increases when accelerating; occurs at all speeds and at idle. People say they know when I am approaching they can hear my car from about two blocks away.
My regular 20 year mechanic checked transmission, replaced timing belt (at 65K; now have about 74K); all idler pulleys; checked alternator; He thinks is is the AC drive pulley on the compressor; Hyundai dealership did not know what it is; laymen have suggested is is a power steering pump, reservoir issue. Power steering fluid level is fine. Otherwise, the performance of the car is fine.
Engine is 3.5L V6; 2004, about 74+K

I remember that my 2005 Prius had a short whirring noise when I shut it off, as some coolant fluid was moved around.
But my 2010 Prius has been pretty quiet at shut-down, until recently (has it always been there, or now that it's cold weather?) I noticed there's a very faint whirring noise coming from the engine compartment at shut-down. It lasts for quite a while -- almost a minute, then stops.
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.
View 2 RepliesMy 2010 Prius V just past the 24000km mark. I have a buzzing noise coming from the engine bay during startup. It happens when the interior fan is on. You can hear it clearly after you start the car, during the silence of the "boot up", before the ICE kicks in. I can't be sure if it continues to buzz after that because the sound of the ICE drowns it out. However, If I shut off the fan during the boot up, the buzz disappears. Finally, if I leave the fan off and start the car, there is no buzz.
During a recent oil change, a hybrid technician claims that this is normal. It used to happen infrequently but now it is consistent, so if it was normal, I should have heard it when the car was new.
When I'm driving with Windows up and audio off I can hear this hollow road noise, static buzzing sound from my back right side.
View 11 RepliesI'm currently using a 2010 Impala as a loaner. I had bought a 2005 Hyundai Santa Fe from a dealer and 5 days later the engine blew. I've been using loaners from them for over a month until the engine is replaced or I decide on a different car. They have a junkyard engine on the floor, but they only have one mechanic so things don't get done on time. This Impala has 107K.
I did the carfax thing and it was a rental for the first 2 years, then owned privately. Occasionally the ABS light and t/c light come on but I'm convinced it's a chafed wire because it seems to only come on when I turn the steering wheel a certain way. They had checked the codes and came up with nothing 'wrong', which makes sense to me... it seems like either a crappy connection or chafing or something. This will need to be addressed and fixed before I sign anything but....
My dilemma right now is this: The roads are currently snow packed. If I punch the gas pedal from a dead stop there is sometimes a slight hesitation and a whirring sound, oddly enough it sounds a lot like a windshield washer pump. The car runs flawlessly otherwise. I asked a friend who also owns a 2010 Impala and he says he's never heard such a noise. I don't see how anyone could miss it. If I disable the t/c, there is no noise.
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?
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.
View 7 RepliesWent down to my garage after the Prius had been off for at least 5 hours and heard a whirring kind of like a fan in the back half of the vehicle. I had never heard this before and it went on for at least 5 minutes then quit. My garage was probably around 60 degrees for most of that time, fwiw. Seems like the area of the battery fan but why would that need to run?
View 2 RepliesI've bought a used Prius 2010 V this winter and didn't use AC until summer. Now that it's summer I have noticed that AC compressor is pretty loud (esp. when turned on for a few seconds) - loud enough that it can be heard even when engine is running but faintly. Some vibration from compressor also can be felt when not moving (parked) and touching brake pedal. Noise is about as loud as mobile phone left on vibrate on a wooden desk, but higher pitch and a bit muffled, or as loud as a climate control fan on max setting. Would that be normal?
View 9 RepliesI keep my 2015 RX 350 in the garage, and last night I noticed a humming or buzzing noise coming from it. I switched the ignition to accessory position and turned it off and the noise stopped. A search here turned up many discussions noting is is the gas evaporation leakage check valve and it is a normal function of the vehicle. My question, is this some sort of pump that is running and causing battery drain?
View 3 RepliesI have a new 2014 RX350, and around the 500 mile mark I began hearing a faint static/buzzing noise that is definitely noticeable when it is very cold outside. It seems to be related to the braking system (i.e. when you press and release the brake pedal), but I have heard it when I'm just driving and not touching the brake pedal. It almost sounds like the car's electronics are going through a self-check, but it is audible. Took my RX to the dealer and they said that the noise is "normal" and that all third generation RX's have that noise - something to do with the brake pedal modulation? All I know is that it is annoying, especially when everything else is so quiet when you drive without the radio on and the fan speed turned down. Definitely disappointing in any car but especially a Lexus.

View 4 RepliesI had never been in a Prius until I bought my own 12 months ago. A relatively loud whirring noise accompanied me everywhere I went... "Oh, that's just the electric motor doing its thing!" I would tell myself and my unknowing passengers...
It was my TOTALLY shot tires. Oh sure, they had tons of tread life on them upon purchase, but they lasted a scant 22K miles, got horribly scalloped, developed stress cracks between the treads, and aren't even LRR tires! Indeed, beware of the Bridgestone Potenza Grid019.
The three miles it took to drive home on the TrueContacts were an automotive epiphany. I had no freaking idea how quiet this car really was! Even at highway speed! I feel like a fool.
Well, now I've got an LRR tire, a 6 year/90K warranty, and did it for about 400 total. Shipped to my door for about 350, local place mounted and balanced them for 50.
I have a 2005 Prius with 218,000 miles. Over the past month or two it's started making a horrible noise, which has finally gotten to the point that I can barely stand driving it. I used to keep my radio around 25 or so, but now need to crank it to twice that to hear anything. I can't tell what it is - it sounds vaguely like wheel bearings, but somehow different. The front bearings and a trans drain/fill was done by an independent shop 6,000 miles ago. That shop says the noise is the transmission and definitely not the bearings. My Toyota dealer says the noise is the bearings and definitely not the transmission.
Here are two videos I took this afternoon, which seem to more or less capture it, though it does sound a bit different recorded on a phone than in the cabin:
(this one has a clearer example of the noise)
Background:
I didn't have any complaints with the car until just before the 200,000 mile service was due, when I started hearing front bearing noise (I've had bearings done in about 5 vehicles, so it sounded pretty obvious to me). I brought it to the dealer and was quoted an outrageous amount for front hub assemblies (they told me they couldn't do the bearings, only the whole hub assembly), sway bar end links, alignment, transmission flush, tire rotation and the engine top end service.
I got a much better quote from my local mechanic who I've used for about 3 years, so I had him do the work. This was back in June, at 212,417. He said that they'd never done the flush on a Prius transmission before, but they had the shop manual and were sure of the procedure, and that their Valvoline rep confirmed the correct fluid, and gave them a written warranty in case of any problems. He did note that "a fair amount of metal shavings came out with the old fluid" when they did a drain and fill (not a flush). He also told me that the tires were worn unevenly so I could expect a bit of road noise after the rotation and re-alignment. They an oil change, sway bar end links, front bearings, tire rotation, alignment and reans drain and fill with Valvoline Max ATF, "Toyota Type WS fluid spec." He told me the same thing about the front hubs being complete assemblies, and the part he listed (PBR930641) appears to agree with that.
