Prius (2010-12) :: Whirring Noise After Shut Down As Coolant Fluid Moving Around
Dec 16, 2010
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.

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.

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.

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.

Our Prius is only a year old with less than 9,000 miles. Everything has been fine with it and then yesterday I took it out of the garage and started to drive and there was the most horrendous grinding/squealing/scraping noise as I started moving from the front passenger side (UK passenger, so left looking out).
I stopped the car and had a look, as at first I thought I was dragging something, but nothing to be seen. Checked the parking brake was definitely not engaged. I then thought perhaps something is caught in the brake pads and it will go in a bit, however even hard braking didn't seem to change the noise at all.
Carried on (I was going about 7 miles), and as I drove it would gradually get quieter, and then get louder again, with the occasional "clang" sound almost like a spring under tension suddenly moving.
Towards the end of the journey it had started to go quieter again, but with the window down you could still hear constant squeal/grind.
Parked the car, was away for an hour, came back and set off home and the noise was totally gone. Entirely silent all the way back home! Now I don't know what to do - whether it will come back, or whether I should take it in to garage for them to look (even though it's now not making any noise).

I noticed my car hiss and hum from under the hook after shut down, for a few minutes. What is it doing?

I'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?

Well my wifes Passat blew a coolant hose and shut down. Now when you try and start it it makes a terrible clanking sound. I'm about to start tearing it apart today. She has the v6 30v...

I just got a 2006 Prius and I brought to Toyota dealer to do a regular oil change. After that, been told that I'll need a Inverter Coolant and Transaxle fluid change in next maintenance point.
This prius already has 111,000 mile now.

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.

I've noticed that if I press the EV button when stopped at a stop sign or red light, I can get the vehicle moving up to 25 MPH with the battery. This must save fuel. But I wonder if I am doing something that causes problems with the battery, motor, or other systems.

Ever since I got my 2010 Prius (about a week ago) I always get a little scare whenever I'm backing out of a parking place. The Prius seems to think that the ideal time to start the ICE to warm it up is when I'm moving backwards and halfway out of the spot... which, of course, causes a little vibration in the car and makes me think I hit or ran over something. It really scared me the first time... especially since I had only had the car a few hours then and I'm mostly used to it by now, but every now and then it catches me off guard.

I've been experimenting with 'B' mode while commuting. While stopped at a light, the ICE never shuts down. Is that normal? It seems like it should, regardless of the drive mode. The ICE was fully warmed up (190 F). I believe the battery was fully charged, as well. It tends to stay charged while in B mode.
If I switch from Drive to B while stopped at a light, the ICE stays off until the car starts moving. But if it was in B mode already, it never shuts down when the car is stopped.

I have a 2010 Honda Civic (automatic transmission) that has about 38K miles on it. For months now, it has been making a very gentle metallic rattling noise after going over bumps and at highway speeds on our "rougher" roads (crappy PA highways). I took it to a Honda dealer about 10K miles ago, and had them inspect the heat shields and take it for a road test, but they found nothing and said the heat shields were fine. I was content to turn up the radio a bit and ignore it (sometimes Hondas just rattle). Today, however, I turned a corner on a residential street and suddenly heard a metallic shrieking noise coming from the right front of the car that didn't go away until the car came to a full stop.
I turned the car off and took it for a quick spin around the parking lot I was in, and it continued to make the noise when the car was moving... forward and reverse. It got louder the faster the car went. Disturbed, I called a tow truck and had it taken to the Honda dealer, who will examine it tomorrow when they reopen. The last time my brakes were checked, which was only a few months ago, I was told that the front brakes were 8s and the rear brakes were at 4, so I don't think the pads are worn down yet.
I don't know if the soft metallic rattle and this noise are related, but they're coming from the same area of the car. It is getting inspected and having an oil change tomorrow as well, since both are due very soon. I know I will find out tomorrow, but I was hoping someone could put my mind at ease and settle my curiousity as to what this might be. There was nothing hanging down from the bottom of the car and making contact with the road, and there are no maintenance lights or other lights lit on the dash. It has been a well-behaved car so far, but it only has 38K miles on it.

Changing my oil today, been awhile since I had the hood open for an inspection a year maybe about 5 - 6K miles
It's been about 2 years since the prior owner had it in for a service, I recall they had it in right before we purchased it in August 2008
I live in Miami Beach where it's HOT
I noticed the inverter coolant level is no longer at full It's hard to see where it's at, actually
It's not below low, and it seems to be at least up to the bottom of the double seam that wraps around the tank, but I can't see where it levels off behind the seam
Should I be concerned enough to take it in to the dealer and pay them to hunt around until they find a small leak, or is it normal to lose a small amount of coolant over the course of a couple years
Should I just buy their high priced Toyota Super Long Life Coolant and top off the extra 1/8-1/4" or so until it's at FULL?

Or at least, I assume it's the Hybrid Drive. The service campaign to replace the inverter pump was completed on Friday. The Coolant Control Valve was replaced today (I TOLD THEM to have that part for the service on Friday, but I digress). I'm now seeing red fluid dripping under the car. It appears something wasn't tightened down correctly.
Given that it appears to be a slow leak, and I need to get the car back to the dealer to fix it (40 mile trip), should I make them tow it back at their expense, or is it safe to drive it that far? I have NO replacement fluid to add in the meantime, and if I recall correctly, that's a dealer only part.

My original intention was to replace the engine oil in the car. I was in a hurry(yes....I know) I could not find the oil drain plug. I did find a large bolt which turned out to be a drain plug for the inverter coolant instead. The instant the fluid drained from the car, I knew it was not engine oil. I did not know the drained fluid was inverter coolant. It had the color of a transmission fluid but significantly less viscous.

I purchased a 2008 Prius with 117,000 miles lat month. I took it to a friend's house recently. When he was looking at the car, he told me that my coolant level is low and put some coolant in the reservoir. The next day when I was driving the car I was hearing a rattling sound every time I pressed on brakes. I could not figure out what could be the reason. The sound went away after couple of days. Today I was going through the manual and noticed the place where my friend put coolant in is actually brake fluid reservoir. It looks a lot like coolant reservoir of my other car. So now I am wondering what could happen if coolant goes into brake fluid reservoir. Will it harm my brakes? It has been about 2 weeks since that incident happened.

Went 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?

When you put the car in park what exactly stops the car from moving. In other is it a brake of sorts or ??
