View 10 RepliesTouareg :: Strange Noise From Passenger Side Engine Compartment
I have this strange noise coming from the engine compartment on the passenger side of my vehicle. Here are the characteristics of the sound:
1) Sounds a bit like a skipping tranny. Fast paced creaking type sound.
2) Only happens when coasting and the car is up to temperature. Meaning when I'm accelerating or braking the sound is not present.
BTW, the vehicle has 28k-29k miles and is 18 months old.
Prius (Gen 2) :: Noise Coming From Engine Compartment After Shut Off
I started noticing some strange sounds coming from the engine compartment after shutting off the car ( a 2007 with 90K miles). It's different from the hum for several seconds that I often hear after switching off the car. This one is a squeaky rough sound like a small motor wearing out. I think it's from the driver side of the engine compartment. Is that where the inverter pump is? This car didn't have any record of needing the inverter pump changed for the recall as far as I could tell.

First off it's a 2008 Prius with 80K on it.
There is a new sound that has started coming from the front of the car in the engine compartment or even lower. It is a turning turbine like sound that is mostly obvious when driving at 60 mph, but my guess is that it is always there, but not as audible at lower speeds. The air and heater are both off and have no effect on this sound. The only thing that could have had anything to do with it is that a day or two before, the tires were low so I filled them to 40 psi. The other thing is that it clicked over to 80K the last week and the friendly red maintenance required light came on.

View 2 RepliesPrius (Gen 2) :: 2007 Whirling / Vibration Noise Coming From Engine Compartment (with Audio)
I would describe the noise as a whirling/vibration sound that can be heard as soon as the gas engine portion of the car kicks in (even in park) but gets louder and more noticeable as the car is in motion, especially at highway speeds (55 - 65mph). Opening the hood and listening to the engine block, the noise is definitely coming from around the area of the silver-covered portion by the driver's-side, which I believe is the hybrid synergy engine. The noise has gotten to the point where I really get bothered by it driving anywhere, and I have to turn up the radio to try to drown out the noise.
View 2 RepliesPrius (2004-09) :: Squeaky Moaning Noise Coming From AC Unit When Switching It On Or Off
I bought a 2005 Prius base model with under 77K mi. A month after owning it, and about the time the weather got hot enough to need AC, I started hearing a squeaky moan (ish) noise coming from the ac unit when switching it on or off.
I took it in to the Nissan dealership and they listened and ID'd the noise as the "blender", and told me it was nothing to be concerned about (I do not believe that) and it's just a normal blender noise for an 11 year old car.
I think they didn't want to deal with it at all. (not that I'd want to spend the money, either, because so far the AC is working fine, but I can't shake the concept that it shouldn't be making that sort of noise at all (it wasn't there when I bought it) . I think it IS something that will lead to needing some sort of repair. Should I bring it somewhere else once my warranty is up?
What I am talking about? Should I be worried about this sound? (which seems to be getting ever so slightly louder each time).
Accent LC (2000-05) :: 2004 - Constant Hissing Noise Coming From The Middle Of Engine Compartment
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.

View 9 RepliesPrius (2004-09) :: Strange Engine Noise
I bought a 2007 Prius with 198,000 miles on it. Since then I've got it up to 200,000 ish. The previous owners took very good care of it, and did not encountered any severe issues.
I recently took it in to a toyota dealership for the free inspection, and they said it was in remarkably good shape. I asked about the engine noise, and they took it for a drive and said everything sounded pretty normal, at least compared to the prius with 130,000 miles on it that they had apparently just serviced before me. I went ahead and lifted up the hood, set my phone recording at the front of the car, and started it. I let it run for a few seconds, then shut it off.
Prius (2004-09) :: 2007 - Whining Noise From Engine Compartment (Proportional To Acceleration)
I need to diagnose an issue I've had with my 2007 Prius with 79,000 miles on it. Several months ago I noticed a distinctive whining/humming noise coming somewhere from the engine compartment of the car while driving. The noise may be present at lower speeds, but the volume of the noise appears to increase proportionately with my acceleration and as such is most noticeable at highway speeds of 50 - 70 miles per hour. As I accelerate faster, the noise level seems to increase. If I take my foot off the gas and coast, decreasing speed, the whining noise gets lower in volume. I believe I first noticed this noise about 6 months ago, but wasn't more proactive about it like I normally would be because at first the noise didn't seem overly loud and my extended warranty unfortunately was up once I hit 77,000 miles. Now 6 months after I first noticed the noise, I believe it's definitely louder than it was when I first heard it, so much so that I can pick it out over the radio being on at a decent volume.
After checking some forums I thought the culprit might be a wheel bearing. I took it into a local Midas shop at they informed me that my passenger-side front wheel bearing was actually breaking apart in pieces. Obviously I had that wheel bearing replaced but I was also hoping this was the source of the whining noise. Unfortunately that wasn't the case as driving it home the noise was still present. They also said the tires were not balanced properly (from my Toyota Dealership no less when I had them install new tires) so I had the tires rebalanced as well. They did take the car for a test drive but probably stop looking for issues with the car as soon as they saw the wheel bearing in that condition. Also that shop does not specialize in Prius' or hybrids so they might not be able to notice the noise that shouldn't be there like I can.
Other than wheel bearings, where this noise could be coming from. Some posts on here possibly pointed to the ICE water pump or transaxle fluid (which as far as I know has never been replaced since I bought the car new).
Prius (2004-09) :: Strange Engine Noise - Power Supply Malfunction
I do a lot of diagnostic and keys programming but my mechanical knowledge isn't' that good. I had a minor accident last week and a car hit my Prius from the passenger front corner, Areand left a small dent, check the red X in the pic.
I noticed after the accident that the engine noise was much higher, I checked all ECUs with Techstream, I found only one error on the Transmission ECU:
C2318 Low Voltage Error(Power supply Malfunction).
Cleared it and didn't show again even after driving 200 milesIs
there anything behind this area that can cause that noise? or something responsible of reducing the engine noise might be damaged or broken?

View 3 RepliesToyota - 4runner :: 2007 - Low Rumbling Noise Coming From The Engine Compartment
So, I have 100K miles on a 2007 4Runner (V6) and after having my radiator flushed at the Toyota dealership service dept, I get my car back and now hear a low rumbling noise coming from the engine compartment. I hear this noise every time I turn on the air conditioner, and sometimes even when it's off.
I took my car to Toyota today and after getting the service advisor to acknowledge the noise, I get a call 2 hours later saying, a) that no noise was identified by the technician; b) nothing wrong with my car; and c) I can come pick it up.
It ain't my imagination. Clearly, something is wrong. What it is? Should I take it to another service department? This kind of thing makes me crazy!
Pontiac :: Persistent Ticking Noise Coming From Inside The Engine Compartment
I have a 2001 Pontiac Grand Am with about 160K miles on it. Over the last month or two I have noticed a persistent ticking noise coming from inside the engine compartment. It sounds like it might increase in frequency along with the engine speed. It is loudest when I pull up in a drive-thru or next to another car and roll down my window. It is audible when sitting or while moving. Doesn't seem to make a difference if the car is hot or cold. I checked the oil and it appears to be full. It sounds like it's coming directly out of the engine block itself. I get the oil changed every 3,000 miles like clockwork.
View 3 RepliesGolf IV R32 :: Strange Ticking Noise Coming From Engine Bay
About a two weeks ago, I had a CEL pop up. I brought it in to the stealership to get it scanned. I don't recall what the exact code was, but the description was something to the effect of "Cooling System Performance." I hadn't noticed that the engine temp was any different than it had ever been, so we kinda figured it was just a bad sensor. We popped the hood just to take a look at things, but he didn't really notice that anything was off. I thought the engine sounded a little difference. It wasn't idling rough, but there was a very subtle ticking noise. He didn't think anything of it. So he cleared the code, and sent me on my way.
The code came back a few days later, but disappeared about a week ago. Since then, however, my .:R has been feeling a little different. Like I'm losing torque. The ticking noise has become distinctly louder, although I can only hear it when I pop the hood. Last night, i was listening to it, and there are two separate noises, coming from two different locations. One is coming from the left side of the engine, most likely from one of the belts. The other is the one that worries me the most, as it's quite a bit louder. This ticking noise seems to be coming from the engine itself. The longer I let the car idle, the louder it gets.
One of my friends took a listen, and he suggested that it could be a blown piston ring. This would explain why I'm losing torque, but I haven't noticed any blue smoke coming from my exhaust.
Corolla / Matrix 2009-13 :: Rattling Noise Coming From Engine Compartment When Drive At 60+ Mph
I have a 2009 Toyota Matrix S. There is a rattling noise coming from my engine compartment whenever i drive 60+ mph. It sounds like it's metal on metal. Nothing is loose inside. I took it to the dealer and they told me the water pump bearings were bad and replaced my whole water pump. That didn't resolve my problem. The rattling is still there.
