Saturn - Vue :: Loud Hissing Noise Coming From Back End
Jan 28, 2011
This morning when I pulled into the garage after taking my daughter to school and shut the car off, I noticed a very loud hissing noise coming from the back end of my car, underneath somewhere. When I came back out an hour later to leave for work, it was still hissing. I drove to work and all was fine, but when I went out to the lot after work my car was completely dead.
I tried jumping it, but it wouldn't even take a charge. I had to find a ride home and will get it towed tomorrow. I'm sure the hissing noise is the cause, but what's going on. My car has never given me any problems--it's run perfectly for almost 150,000 miles (5 speed manual transmission). Maybe this is the end?

I have a set of ST that were put on a year ago. I raised them up in October for the winter. This past Saturday I lowered the car back down. As soon as I did I have the loud noise coming from the front passenger side.
I know it's not the top hats because I had that issue and replaced it and not the same noise. It is not the clunk that people associate with springs.
The noise seems to happen when spring/strut expand and retract.
Called ST today and they said if I had the car all the way down it is my fault. WTF? Why would you make a coil that is adjustable and the customer is able to go all the way down and then say it's my fault IF strut is blown?
The car drives straight and smooth so I dunno if it is blown. Could it be because of a build up of crap between the springs over winter (I saw some.)

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?

I feel as though my APR turboback has an exhaust leak.
There is a loud hissing noise that overwhelms the exhaust, turbo and engine noise. What it is. Sounds like a loud hissing when then turbo begins to kick it. Not normal, and it slowly has gotten worse and more noticeable.
I have a feeling its the downpipe, but I can't check it myself. When i give it gas and the hood is open (at a standstill obviously), the engine compartment smells like exhaust fumes.
Could be playing mind games with myself. What do you all think? Any way to surely test and see? I am taking it to dealership on Tuesday to double check.

So for the last 2 days I heard this loud hissing noise from the passenger side of the car and also noticed that my boost won't go over 24lbs. So I called my local tuner shop Innovative motor sport in Stratford and was told to bring it down to check it out. Less then an hr later I was at the shop and we where putting it up on the ramps to get under to take a look. I took out the panel covering under the motor and looked up to find a hole in my turbo outlet coupler. Tom at IMS had an extra laying around and let me use it till I get a replacement.

My 85' 740 GLE has been having some troubles lately, A nasty loud hissing noise is coming from near where the oil pan is and it is more prominent when i apply pressure to the gas pedal or sometimes when my foot isn't on the brake or gas. The first 5 minutes or so of the drive are fine, you hear the hiss but there are no noticeable performance issues. After a few minutes the noise gets a little louder and starts to effect the acceleration tremendously to the point where it'll take me roughly 10 seconds to hit 30 mph from being stopped.

So I was sitting in my wife's car and hear a clunk while the car was in park sitting in the driveway. She said it had been doing that for a few weeks now. The clunk seems to happen every 4 or so seconds while idling and is coming from the engine compartment somewhere. There is also what seems to a hissing or sucking noise that sounds like it is coming from in the dash somewhere and also happens about every 4 seconds during idle. I really haven't had a chance to look into what the problem(s) may be or if they could be connected. I am really not sure what the clunking at idle could be. I think the hissing noise is a vacuum leak I could probably hunt down when I have a chance.

I drive a 1997 Saturn SL1, 295,000 miles. Great car. Good gas mileage, very, very low maintenance. I cleaned the engine about three years ago with an engine cleaner (Gunk?). When I turned on the engine it started to make a loud noise. The best way to describe it is a loud whining noise. It appears to be coming from the AC. When I turn on the AC the noise gets quieter (but it's still annoying). The noise does not appear to have affected the car's performance, but it is loud and annoying. What the problem is?

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.

Usually after I run the car in manual/sport mode, I begin to hear a high-pitched 'hissing/whistling' noise coming from the engine. It sounds like a vacuum leak. It is audible while driving with the windows down.
I am having problems pin pointing the source, but it sounds like its coming from the center block. What is the right direction to the leak? It starts exactly at 1500 and cuts off at 2200 rpm (while in gear). 1500 to 3000 rpm while in park..
I have a Takeda intake installed and I re-tighten the fittings.

My 04 hyundai accent about 2-3 months ago acquired a hissing noise which seems to be coming from the middle of the engine compartment. The car only has 100,000 miles on it.
It is a constant hiss that only stops when the gas pedal is pushed initially. I have looked all over the car and can not see any fluids leaking at all. It is pretty loud and can be heard easily outside the car when the car is on.
I hooked up my obd2 reader and found these codes:
P0304-Cylinder 4 misfire (I notice it when the car sits at idle for about a minute)
2x P0121- Throttle Position circuit range/performance problem
2x- Evaporative emission incorrect purge flow.

We have a 2000 Saturn SL2 (120,000 miles). Last night we drove to L.A. and back (from San Diego) , so about 250 miles round trip. For the last 45 miles or so we had the radio on quite loud. At some point in that 30-45 miles the engine developed a very loud knocking noise - like rocks being spun in a tumbler - which we noticed when we got off the free-way and turned down the radio.
This noise did not effect the way the car handled as I did not notice anything when the radio was up. We have been listening to a lot of sounds and I am concerned it could be a Rod Knock - it sounds a lot like this [URL] ... from inside the car, outside it was more of a constant pinging/thunking noise - less gravel sound.
So my quandary is this, our mechanic is not open Sundays so I cannot ask him, but when we take it to him tomorrow, do we drive it or tow it? If the rod is starting to go I do not want to inadvertently do more damage by driving it. The mechanic is 8-10 miles away. We can get their either on the freeway or through surface streets.

Looking for some input on a recent "hissing" noise coming from eng compartment. It's only noticeable during initial acceleration, and sometimes at the beginning of gear changes. I am assuming its tubo and/or exhaust related, as I've noticed a strong exhaust odor in the cab as well. I wasn't under load when the problem started but i was under rapid acceleration. Not noticing any fluids or oils leaking. No warning lights have tripped, as of yet.

I drive a 94 Saturn SL1 as a part-time delivery driver for a pizza shop. Recently I bottomed out on someone's driveway. I could hear the bottom of my car scraping against the asphalt. It took several tries (in my 5-speed) to free myself from this trap. Since then I've been hearing a pretty loud "clicking" noise from the passenger side of the car every time I make a turn, where a small turn or a big turn. My mechanic replaced the left axle and the right boot, saying that both were defective. However I still hear the noise. What can I do??

I have a 2004 Saturn Vue, V6, FWD with ~170K miles. It has a rotational noise coming from the front end that I can't find/fix. My regular mechanic has replaced both front wheel bearings, the rotors and brake pads. Tires have ~35K on them and no noticeable uneven wear. They were rotated and the noise didn't go away. Mechanic thought it might be transmission, but transmission shop disagreed, but couldn't suggest an alternative. The noise is speed dependent. Initially you had to be at highway speeds to detect it, but now you can hear it at 25 - 40 mph as well. Best description is a "whoop-whoop" sound. You cannot hear the noise if the car is parked and you rev the engine.

About 3 weeks ago my car,a 2007 saturn vue 6cyc., started making banging noises in the glove box when I start the car. The noise last for about 10 seconds and is very loud. The car runs great, no problems.

Fan is pretty clean. Before re-assembly it will be blasted with ~100 psi from an air compressor. Driving around like this is fine for a while to check diagnostics. How noisy is normal? This is the first time I noticed the noise.
We've owned this silver 2011 Gen 3 from new and it now has 37K miles after about 3.5 years. Today it's ~70F in Atlanta, so not hot compared to how it will be soon. We had the s/w recall done about six months ago and I've possibly not driven the car since (have a few cars).. my wife drives it most days and did not notice probably due to music but I felt it was very loud like there was hole in the side of the car (first thought was some vent to the outside became stuck open but the vent near the auxiliary battery is fine).
Is there a way to read the fan speed via Android Torque and Bluetooth OBD? Should I disassemble the entire length of the venting? Might there be something inside there causing a blockage?

I have an 06 2.0T passat sedan. After a year, I started getting this loud rattling noise from one of the panels in the back everytime I hit a bump in the road. At first, I thought it was the rear tray behind the seats. But after sitting in the back with my son while my wife drove, I realized that it's a panel on the ceiling. It's this long thin panel that runs along the width of the rear ceiling, right along the top of the rear windshield. I'm thinking I could just remove the panel and put some sound proofing material or adhesive foam pads or something.
