I own a 2004 Volvo S60 2.5T AWD. I have noticed that usually when I am driving and it starts to rain heavily, there is a loud siren sound coming from the engine area. This sound stays till it doesn't stop to rain. Also, if I don't step on the accelerator, the sound goes away. I have taken it to the dealership a couple of times but haven't been able to replicate the sound.
View 18 RepliesWe were driving last weekend in a heavy rain storm when our 2004 XC70 started making a loud siren noise. The noise increased with acceleration. We pulled off the road, turned the car off. When restarted the sound was gone, but then returned again when driving in heavy rain. Any clues as to what is causing this noise and if it needs attention?
View 21 RepliesSo, first, I need to tell that my car was just turned away from the only mechanic that is a "volvo mechanic" in the region because he said it grumbled and shook too much and it was too much of a liability.
There is only one thing I am concerned about, because it has been grumbling and shaking since I bought it five years ago and it hasn't gotten worse (so why worry!)
This car is a 1991 Volvo 740 sedan with 250,000 miles, a 4-cylinder gas engine and rear-wheel drive.
I have a siren sound coming from the front end, but only sometimes.
When I first start moving forward, I hear a "whooooooooOOOOOOOOOOOPPPPP!!!!" (sounds like a siren) for about 50-75 feet while I am going about 25-30 MPH. It only happens when I first start rolling forward when I first turn the car on from sitting for a while (3 or more hours). If I come to a stop, I don't hear it. If I park and run in somewhere and come back soon, I don't hear it.
I have been hearing a small "whoosh whoosh whoosh" sound coming from the front end that gets faster the faster I am traveling, and I don't know if that is related.
My XC70 makes a weird whistling type noise in heavy rains that last a long time. It doesn't do it in light rains, or rains that are heavier but don't flood roads or collect water on the shoulder or slow lanes, only the really heavy, hard to find the road type.
There are no warning lights when it happens, turning off everything, except the car and windshield wipers, doesn't work. Pulling off the road, works after about 30 seconds, but then we start again, and it continues. This is only happening during really heavy rains, is scary, and I don't have a clue what it's doing or why nor does my mechanic.
We have had a 2004 Volvo XC70 for two years now, problem-free. But recently we experienced a strange, new thing. We were driving in a very heavy rain in Maine (during the hurricane) and suddenly the engine began screaming...not at all like a loose belt or bad bearing, but really loud, seeming from right front. We stopped, no idots lights came on. Began again, soon the same thing. Stopped again, waited, then took off again, with rain lessening. No further problems the rest of the drive back to Vermont. But now, we occasionally have the screaming, only briefly and ONLY when it rains. It concerns us a bit.
View 3 RepliesI drive a 2008 Cobalt SS turbo. its been a good car and I haven't had any major problems with it aside from the small stuff.
Well for the past few months I've noticed that, whenever i drive in heavy rain or in snow etc I will get a loud Growling/whining noise from the transmission area. Now it will do it while in Neutral, 1st etc and when stopped it will go away. If I stop the car for a few moments, the noise goes away until I hit another puddle and then it comes back again.
I also feel a "knocking" in the shifter and I've noticed its vibrated really badly for awhile now.
the caveat to this is it ONLY does it when its wet outside. I've taken it to GM a few times, and even showed the service manager the issues when it was raining out and he said everything was fine. The car never did it when I first purchased it.
I should include that there are some aftermarket modifications on the car. Catless downpipe, new intercooler, lowering springs. stock exhaust and stock turbo.
2001 Passat Wagon ... After a heavy rain last night I noticed a very wet driver side floor area. My car was parked and I've never noticed any wetness while driving. What are the steps to take to figure out where the leak is?
View 6 RepliesMy engine light came on last November which was diagnosed as “fan clutch seized”. My automatic transmission’s coolant fan clutch was replaced. Since then and on more than one occasion while returning from skiing in the mountains, I will hear this loud whining sound coming from the transmission area. I only hear it when the car is de-accelerating and I have not been able to replicate it once I am out of the mountains and the outside temperature is warmer. Is this a faulty fan clutch issue?
View 2 RepliesMy '02 Impala makes a low moaning sound only in heavy rain and only if I am forced to drive through a large puddle.It first occurred a year ago after it had it's catalytic converter replaced due to the recall. The dealership mechanics checked their work and could find nothing. I tried spraying it with a garden hose under the car and under the hood while moving the throttle, still no sound. A local, and very thorough mechanic, heard the sound on a rainy day, but could find nothing. He could see nothing wrong, but thought that changing the serpentine belt would work. I replaced it with one from the dealer, but the sound still returns on rare occasions.
View 3 RepliesProblem description: A loud metallic rattling sound from under the car under moderate to heavy engine load, only when engine/exhaust is/are cold. It is noticeable from within the cabin with the windows rolled up and the sunroof closed. Crack a window or the sunroof and it's pretty loud. The first time I heard I, I thought "this is not good".
This is not an octane ping or valve train noise. It sounds like a coffee can with marbles being shaken in concert which what might be the rapping of a V8 engine's exhaust. I had a Sunbeam Tiger that rapped in the upper rpm ranges and this reminded me of that but instead of rapping, it shakes a can with marbles.
There has been much discussion and speculation as to what causes this. It does seem to occur only with late - 04 and up V8 Touaregs with the "sport" exhaust that replaced the "std"(?) exhaust used on the majority of the 04s.
Observation: I looked very closely at the heat shields, looking for ways they could rattle. On the passenger side (LHD), the heat shield has three main sections:
- Front: around/near the secondary cat (tightly secured)
- Rear: around/near the rear differential (tightly secured)
- Middle: between the two mentioned above (loosely secured)
The three sections overlap a little where they meet. It was very easy to tap on the middle shield and make a loud metallic sound. I put my finger between the two shields (where they meet) to isolate the two metal pieces and tapped again, and the noise was gone.
Theory: The harmonic resonance of the exhaust under load vibrates the middle heat shield and it rattles against the front and/or rear shields. As the shields heat up, they flex enough to provide clearance between each other and the noise goes away. This may be unique to the "sport" exhaust if (and I am only speculating) the heat shields were changed (in design or fitment) when they changed the exhaust.
Experiment: I tried a very simple experiment. I slightly bent the edges of the middle shield (~1/2 inch) where it was coming in contact with the front and rear shields. The allowed me to tap rather hard on any of the shields without them rattling against each other.
Result: I make the tweaks to the shields Sunday night. When I drove to work this morning, I put the transmission in sport mode and ran WOT until it shifted. Normally, I would have heard the sound (very loudly) but it was gone. No metallic sound. Not completely convinced, I repeated the experiment on the way home and, again, the sound was gone.
Summary: It was cool out when I was going to, and from, work (64F) and this would normally be the perfect set up for making the sound. I think that tweaking the heat shield has solved the noise on my Touareg. I am tempted to go back under there and pop-rivet a little brace between the shields so that they cannot rattle against each other again. On the other hand, I may just leave it be and do the pop-rivets if the noise comes back.
Anyway, I was excited to find a potential solution for my Touareg and wanted to share it will you all. I will post back after a while and report how it goes in the long term. Lastly, I really liked being able to put the air suspension in xtra-offroad and get under the car (easily) without using a jack....
I have had a 2000 f250 crew cab for little over a year now. Two previous times, after heavy rains, the cabin light would blink on and i would get a buzzing sound under the dash. I would solve the annoying buzzing sound by opening and closing the door. After a few times, it would work, but my clock and radio could go on without the key in the on position. The next time i used it, no problems... so i put that worry in the back of my mind.
This morning it rained really heavy, sideways type of rain. I opened the door and noticed a small puddle on the vinyl floors right where my left foot goes. OH,oh i thought, but the truck turned over and ran like normal. I picked up a heavy load of hickory in the bed and hopped back in and noticed my speedometer jumping from 0- 30 when I was going about 35. The OD light was blinking, but the transmission shifted normally. I got up to about 1700 rpm and the speedo was barely jumping at 53-55. I make another stop to unload the wood and go back home and i get an intermittent buzzing sound on the way home and no speedo. OD light would start blinking before i hit 2nd gear. I also noticed the odometer not working (speedo related, right?)
I got home and took the fuse relay cover off and found that if I would remove the #1 relay "plug" (black square box 5 prongs) that dreaded buzzing sound would go away, checked it out , plugged it back in, buzzing back on. The clock light still stays on and radio will turn on without the key. I think that water obviously leaked in over something electrical and i have been searching this and other forms for a couple of hours. I am within a couple of weeks of saving up enough to buy the gauges, exhaust and possible DP Tuner and now this happens?
After several days of rain I found that the drivers side carpet is soaked. Upon further investigation I realized it was coming from underneath the car rather than from the side. I was able to put my hand under the carpet and feel the metal body underneath. It was soaked. I have never had this problem before and have not been in an accident. The car drives very well and has 130 miles. I recently replaced the transmission and was hoping to have this for a few more years.
View 1 RepliesI have a 2007 Hyundai Sonata 2.4l GLS. Staring to get an little noise from the engine about a few days ago. The noise what can only describe as a whirring sound and while in the cabin it sounds like it's coming from the right side and in the engine area, especially after a cold start and during acceleration. It is not very loud(have to turn stereo off to hear it and it only last for a couple of seconds as far as I know. My car now has about 240,000kms on it, and since the noise is coming from that area I am guessing it's a pulley of some sort. Serpentine belt was changed last year. What this noise is? I was thinking it might be the belt tensioner, probably should have changed it during my belt change.
View 1 RepliesI have a '99 Volvo V70 XC AWD that is making a high pitched whine that sounds kind of like a siren at times. Usually goes away if I'm driving at high speed on the highway. It's more pronounced during in-town driving on acceleration/deceleration. Turbo?
View 3 RepliesI've had a used 2007 V6 Camry for about six months now.
I recently started noticing a quiet set of rapid clicks/clacks sound coming from engine compartment/firewall area more or less on driver side. I'm not sure if it was there all along or if I just began noticing it.
It occurs after starting the car, putting it in drive and as soon as I let off the brakes and begin rolling. It might only happen going forward. I will have to notice if it does it in reverse.
It happens rapidly and stops and I don't hear it again until I repeat the steps above after the car has sat a while. I don't believe it will do it again, if say, after doing it once I stop, put it into park and then back into drive and go.
I don't believe it's the CV joints. It does it once and stops and is not related to movement of the steering wheel. It almost reminds me of a relay switching something.
I'll also add that I had a 1995 Prizm and 2000 Corolla that did the same thing. Both were manual transmissions. The click they made was much louder though their cabins were not sealed as well as the Camry. The clicks would happen only after the car had sat a while as soon as the car first started rolling and then would stop. Could it be the same thing in all three cars?
2002 Mitsubishi Montero Limited V6 ... Occasionally while slowing from 15 miles per hour to 5 miles per hour, i'll hear a vibrating sound coming out of the engine area like a gear trying to catch and then when i slow to 5 miles per hour, i hear a snap like it just caught or snapped into place and fixed itself. The car drives fine while this is happening, and at all other times. I have 125K miles on it and it has been well maintained. Originally i thought the sound was coming from the front right tire area and had the brakes and shocks/struts checked... The sound could be more centrally located though. What is that?
View 1 RepliesHyundai Elantra 01 GLS. The main problem is that the airbag light is on and stays on no matter what. This is my girlfriends old car and she tells me that a couple people told her it had something to do with a faulty/corroded connection or something like that... I have been working on this car for about a year and I am finally to the point where I am just ironing out the little kinks. The old engine was bad along with a lot of other stuff, and I swapped it out for a good motor with less miles on it.
I also have recently replaced the alternator and instrument cluster just to name a couple repairs. Now the two things that I want to get settled are the airbag light and the check engine light. The check engine light comes on sometimes and I am almost positive it either needs a new 02 sensor or cat since when it was ran through a code reader those were the two options my mechanic told me it could be. I also hear a gurgling/crackling faint sound coming from the drivers side dashboard/engine area. I am not sure what this is. How can I get the airbag light off ?
My trusted Volvo mechanic can't figure this out. Shortly after starting my car, there is a clacking noise that seems to be coming from an area near the glove compartment. It lasts for several minutes and then stops. There doesn't seem to be anything wrong with the car. I've had it serviced, but can't figure out what causes this noise.
View 2 RepliesI have an 2005 F250 4.2tdi XLT. There is a buzzing sound coming from somewhere near the fuel filter area in the engine bay. This started after changing the fuel filter during a service. Its also difficult to start now. It has to swing for 10 secs before the engine fires. What it could be?
View 4 RepliesMy 2004 Santy 3.5L (I am the original owner) just turned 91.4K miles and all of a sudden a VERY LOUD Engine Knocking sound came from the top of the engine. I have been changing my own oil since new with synthetic Mobil 1 and a new filter every time, and I never had any issues. I changed it last week at 90K prior a Spring Break trip (1350 miles).
Then yesterday after I let her rest for 1 day, I took the kids to school and within 10 miles of my house the ticking HARD loud noise started happening. I pulled over near a shop (within 1 block of where the noise started) and they said...don't drive it it sounds like a lifter collapsed, or a rod bearing or something big...
I had her towed to the dealer and the first thing they told me is to gather all the oil change receipts and a "manifesto" and they asked me how often I change the oil... I said every 5K miles. I change my own oil and have done since day 1.
BTW, Timing Belt, Water Pump, tensioners, belts, coolant, spark plugs and coils were changed last year at 77K miles.
The car should still be covered under the 10year/100K Powertrain and I believe they are trying to build a case so Hyundai can cover this or not...
They still need to tell me what's wrong... I change my own oil so I don't have receipts for "oil changes" and I have a log of when oil was changed...
I've a loud squeaking sound coming from the front of the engine on cold start. This only happens when I start the engine after overnight parking . There are no squeaks when the engine is warmed up or when I start up with a warm engine.
I'm driving an 07 Camry and live in a region with hot tropical weather.

What could be the probable cause of the this and how do I rectify it?
