Volvo :: Hissing Noise From Under The Hood When Go Faster
96 850 turbo auto. 150k .. My girlfriend just informed me there's something wrong with the car. I drove it, from idle to 1/2 throttle it drives fine cruises on up too a hunski pretty quick, but from half to full there's a hissing sound coming from somehere under the hood and while its hissing it feels like the turbo doesn't want you to go any faster. Also from a stop light if you give it full throttle it wont shift out of first unless you let off the gas.
Also when in park if you rev the engine to like 4-5k and let off, very very slowly does it drop back down to idle. The tracs off and abs lights are on! I'll hook my code reader up tonight to see if i can pull any codes.

When I have the A/C running in my truck it idles at like 900 RPM's if not 950 RPM's. It also doesn't appear to sweat like normal vehicles do. Most every other vehicle I've owned sweat when running the A/C it does but just not a lot. I hear it hiss like the drip is hitting something hot when I shut the door on the truck.

Twice during the 6 months that we have owned our 2010 Prius, a loud clattering noise from under the hood occurred upon startup. After shutting it down and restarting, all was normal. It sounded like an engine that was getting ready to throw a connecting rod. The dealer could find nothing wrong and when I contacted Toyota's hot line, they were clueless as well. One service writer suggested the ABS as the source, but I've owned 5 other cars with ABS and never heard anything like it.

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.
Prius (2004-09) :: Loud Bangs Under The Hood - Rough Engine Shut Down
Yesterday afternoon after warming up (car still in park) the engine shut down was very rough. I heard a quick string of maybe 5 or 8 loud bangs under the hood. Sounds like something got loose and banging inside the engine compartment and ready to fall off at any moment. This morning it was just a bit rough but not nearly as scary. Other than that the car seems to work fine.

Ever since we got our 2012 GX, we hear a hissing noise whenever we brake to a stop. Does yours do this? Turn the radio off, and brake at a stop sign...do you hear it? The dealer didnt know what it was. We took another GX off the new car lot and it did the same thing. It sounds like air releasing when you brake.

I just finished replacing my HPOP (Adrenaline Pump from Diesel Site) and fired the truck up and its making a hissing sound from the rear of the motor back by the turbo almost sounds like a tire leaking and its loud enough to hear over the engine. The truck is running and idling good but it doesn't seem to be quite 100% when I step on it.
View 10 RepliesFord - Explorer :: 2003 XLS 4.0 - Overheated / Loud Hissing Sound Coming Out From Under The Hood
My Explorer overheated yesterday. Found a very loud hissing sound coming out from under the hood. Let it cool off filled it with antifreeze, started it up, started hissing again. Found the thermostat had broken. Replaced the thermostat. Filled it up again. After replacing the thermostat I found out the hissing sound was coming from the plastic thermostat housing. Replaced the housing. Again I refilled it with antifreeze.
Started to let it warm up and noticed liquid dripping out of the exhaust pipe. Checked it out. Had a green color to it. Then I noticed the coolant resivor was full up to the cap. I did not fill it up past the full line on the side of the resistor. Tried removing the cap.
Found out it had a ton of pressure under it. Bled off the pressure. Refilled it again. Did not put the cap back on. Tried starting it. Instantaneous geyser. Runs like it is missing on 1cylinder. No oil in the coolant that I can see. No coolant in the oil. Could this problem be caused by a blown head gasket of a crack in 1 of the heads or in the block?

View 10 RepliesPrius (2004-09) :: Dash Lights On With Repeated Hissing Noise
After searching for the Prius that I wanted, I settled on a 2008 Prius Touring with 171xxx miles. The car was at a sales lot 300 miles away. After a few phone calls pertaining to the Prius, I arranged to meet the lot owner roughly 1/2 way in between for the purchase. We met. Owner said that several dash lights came on as they were driving to meet me. (Yes, I believe him.) He talked with his mechanic, and was told that the problem was most likely the ABS control module (p/n 44510-47050). Owner agreed to shipping me a good used ABS module and discounted the vehicle a bit. I drove it home.
The brake, (!), ABS, and VSC lights are "on"when the car is in the "ready" mode. The parking brake is not on. When I walk up to the car (with SKS fob in my pocket) and open the door, I hear a noise that sounds like water running through an outside faucet that's only partially opened. For identification purpose, I will refer to this noise as a "hissing" noise. When in "ready" mode , the ABS system "cycles", with about 4 seconds hissing, then about 10 seconds not hissing, repeated over and over.
In ready mode (under the hood), the inverter pump is humming away just fine, and the coolant can be seen flowing in it's reservoir. My biggest question is that I have read about others with the unwanted dash lights, but not any with this hissing noise. Does the ABS module replacement sound like it will most likely cure the problem?
And btw, after disconnecting both batteries and waiting for the proper time period, is it really necessary to use the insulated gloves? Years ago, I used Toyota repair manuals, and after receiving the Haynes manual, I'm a bit disappointed.

View 4 RepliesPrius (Gen 3) :: 2011 Toyota - Hissing Noise Coming From Rear Passenger Side?
I've been noticing "Hissing Noise" coming from the rear passenger side (rear right hand side) of my 2011 Prius for a few days now. It sounds like the hissing noise is coming from the vent that's located on that side. Not sure what that does, but the hissing noise is usually present when I'm driving at 10MPH or up and it's gone when I'm less than 10MPH or at a complete stop. I have about 32K miles on the car.

I have a used 2010. Came home to my car rifled through (I left it unlocked) door not completely closed, 12v battery dead because of interior lights. Jumped it. Got it into ready mode. Thought I left it on enough to charge the battery. Locked it. Unlocked and locked it with the fob... no problem.
Came back later in the day, now dead and locked. Car didn't come with manual key. Very expensive to replace so i skipped it. Is that now my only solution without damaging the car? How to open the hood so I can jump it?
Elantra MD (2010-15) :: Small Clunk In The Front End Causing Hood Noise?
There is a small clunk in the front end and I think it could be the hood. When I press on it with my hand I get a small clunk. I have had the dealership look at it and they are not sure of any way to adjust it. Most cars have rubber topped screws to adjust the hood for a tight fit, but the elantra does not have it.

I heard noises like a small pump noise and a hissing air sound above the muffler area. The car had been sitting for hours and no key fob close to it. I was climbing under it looking at something else when I heard it. Sounds like a tiny electric motor running with an air hiss. Passenger side. Just bought the vehicle last week. It has 27k miles on it. Had to replace battery the other day. Said battery was replaced a year ago. Wonder if this is hurting the battery? Start great in the morning. Vapor fuel pump?

View 6 RepliesPrius (2004-09) :: Humming Noise Under The Hood
I loved my 2009 Prius until this weekend. I just turned over 31,000 miles and now a loud humming noise has developed under the hood while driving. It has not been cold here and this doesn't start until I reach around 24 mph. It remains while the gas engine is running or I'm coasting with the engine off. The humming is there in D or in N and there no sound while turning. When I am under 24 mph the noise is gone. I have set up an appointment with my Toyota dealer for this week, but wanted to know ahead of time if any other Prius owners have had this issue.
