Elantra XD (2001-06) :: Deep Rattling Sound Along With Very Low Idle
Mar 23, 2016
When I am driving my elantra (engine warm), say I pull up to a red light or I am in a 'drive thru' my RPM's will go to under 500 and normally go under 400 which causes the whole car to shake and sound like it will stall. The car also has the issue with the Air Conditioning on that makes the vehicle have a deep rattling sound along with the very low idle which follows with my lights dimming or lightly flickering.

My mother has a '04 Santa Fe 3.5. Her automobile makes a rattling/grinding sound when around 1000rpms/idle. However, the sound disappears when accelerating and drives like a charm. The sound returns once again around 1000rmps at idle or stop. I have changed the oil pan, replaced oil and filter and even put in a new battery. I'm not an aficionado when it comes to Hyundais (Subaru driver here).Car also has 180k miles.

I was experiencing a slight under hood rattle when ever the ICE would kick in at approximately idle. It would go away if the pedal was depressed beyond the point that the eco light would go off. After scouring the internet, no good answer came up. So I checked under the hood just to see what was going on. Simplest fix ever, the stick that props the hood open had become unsecured. Snapped it back into place and voila, back to normal.

My car started giving a rattling sound when idle 2-3 months ago. If the rev's needle is at 800rpm that woody woodpecker sound comes from the backseats (or maybe not, it's hard to tell). I slightly press the gas pedal and the sound's gone.
I remember the car to be dead silent during the first months, like omg i can hear my heart beating.

When i accelerate there is a loud rattling noise from under the car it seems. It sounds like pots and pans banging together. I does not do it at idle only when u accelerate hard.
It does it in all gears even neutral. if you rev the car in park or neutral with your foot on the pedal steady it does not make the noise. only if you push the peddle quick and let go.
What could this be? It started after i brought my car in to DUNN TIRE for a rotation.
I called them and asked for them to check the noise and the guy denied me and said they don't do that kind of work. only tires and brakes!!!!.

Usually happens after car is warmed up. Rattles only while stopped and transmission still in drive. If I shift into Neutral or Park, rattling stops.
Last time I had a problem similar to this, dealer said it was a heat shield making the noise and they said they removed the heat shield (didn't specify what the heat shield was for.
Now I'm wondering if the heat shield was removed, what else this could be now...planning on taking it in in a few days.

I have a 2004 3.5 V6 that is making a rattling noise when the car is in idle and/or about 1rpm. Sometimes, for awhile now , it kind of screams when I first start it...but not all the time. I know this is a loaded question but what do you think it might be? The screaming noises don't happen all the time, like I said, and very rarely happen together but the rattling is happening a lot!

Driving an '03 Hyundai Elantra. I've noticed that occasionally when turning and also when driving at around 55mph or so, there is a metallic rattling sound that seems to be coming from the front driver side of the car. What this could be?

So, I have heard a little bit about the oil pump bolt issue. However, I am still confused. Was this issue fixed for the 2008 model and what are the symptoms? I changed out my valve cover last night due to a PCV valve failure. The car is running great except there is a slight rattling sound coming from the drivers side of the engine at idle. I know I left nothing around the car that could have gotten in the motor when the valve cover was off. This issue was not happening before changing the valve cover. What could be causing this noise, or is it typical for this motor?

My engine making a deep subwoofer-like sound but it was hard to describe. This morning I took a video and you can instantly hear it, you might need to put headphones on to hear the sound but its very obvious once you do.

So im trying to diagnose my girlfriends issue with her car. When she starts it, the car will make a very loud rattling sound, not really grinding, but like metal on metal contact. Sometimes the sound goes away, but when the car is cold it is a guarantee. The battery light is also on, which was not the case when the rattle first started. I first thought (and hoped) it was perhaps the serpentine belt tensioner as I researched that when it fails it can make a loud rattle sound.
Once replaced, the same issues occurred. So I went ahead and put the old one back on since it was not the issue. Note that the old one and new one both shared the same tension applied to the belt and the pulley was still smooth without issues.
Using a stethoscope to try to determine the location of the rattle a bit more precisely I found the noise to be coming more from the alternator. Weird because I recently replaced it within the last year. I went ahead and removed the tension from the belt and played with the alternator for a bit. The clutch felt good when i used a screw driver to hold the fan and tried to move the pulley. One direction moved with ease while the other direction refused to budge, perfectly normal as I researched. The thing that I noticed that I thought was unusual was the fact that the shaft of the alternator had some play (Video below).
The belt has plenty of tension on it so i do not believe that it is slipping on the alternator. I push the belt with the tensioner engaged and the tensioner does not budge.
I decided to measure the voltage coming off the alternator with the car running and it was at 10.95 which im pretty sure is very low for these cars.

My 2003 Sante Fe has developed a rattling sound in the engine. The oil level has been good. I took it to a dealer for diagnoses and they told me that the engine was gunked up and the timing "chain" tensioner couldn't move to keep it tight and it was rattling. They put some engine cleaner in and changed the oil and wanted me back in 500 to clean it again. I did that again, but the rattle is still there. It gets a little quieter after I have driven it for a while.
My question is doesn't the Sante Fe have a timing belt? If that is the case what do you think the rattle is?

So everything is tight and aligned and all good, but I'm getting this deep squeaking rub noise coming from my front upper strut mounts, but all the bolts are tight, yet it looks like the metal ring inside the strut tower moves a little up and down when you rock the car a bit. And I can feel the rubbing vibration and movement of the mount when I put my hand on/in the strut tower while the car is rocked.

On the way to work this morning in stop-and-go traffic, I noticed a new, weird noise from my week-old 2012 GTI with less than 500 miles on it.
The noise happens when letting of the gas in gear. Doesn't matter what gear you're in or what the engine speed is. Around a second after getting of the gas, there is a loud, depp bass thump, almost like a subwoofer hit from a close-by car. That's what I originally thought it was, but later determined it's something from my car.
What it could be? An exhaust noise? Something hitting? Is this a common noise on the new GTIs?

I have a 2002 V6 Dodge Dakota that just recently lost pretty much all power. It will not go above 20 mph and has a hard time going up any hills. I was driving on the interstate and initially was having a hard time reaching 65 mph. The truck would roar and then shift and then lose power and shift down a gear. Eventually it lost almost all power and is now barely drive-able. It makes a sound like an ATV at low speeds, kind of a deep humming sound. When I punch the gas in neutral in makes the same sound. I have had problems with it stalling before and am at a complete loss as to the cause.

Past a month, I am having a constant *ssssss* sound from under the vehicle when the Car is IDLE with engine ON. It is very obvious when I am standing outside next to the vehicle, I don't know if it's normal or not.

Whenever I am in a parking lot turning into parking spaces or driving slowly around or even turning into my driveway I have a deep creaking type sound that sounds awful. It's either the suspension going south, something with one of the strut bars or the bigger diameter mid pipe making contact with something when the car is turning. Car is noise free otherwise even over soles bumps, just happens to sound nasty when making turn ins going 2-5 mph.

Gurgling/percolating sounds, car started making a few weeks ago. The sound is coming from deep inside our front dash area. We do plan on bringing it to our local VW dealers attention at next scheduled oil change. I started getting this noise as well about a month ago. My passengers commented about sounding like someone sawing inside the dashboard. I do like the percolating description better...
This is different than the other "running water" sound that you get when initially turning the car on. I was told that was normal.... This percolating sound happens while driving and I noticed that it does have the pattern of happening when at slow speeds or stopped in traffic (after driving fast for a while).

So this problem came about after I changed the timing belt on my wife's 05' elantra.
The idle will bounce from 1.5k to 3k exactly and continue this for as long as the car is on. Some times it will stay at some point within that range for around 2 seconds then continue to bounce.
I checked the belt today, and it seems to be tight enough but not to loose either...maybe I screwed the timing up? But would that cause this problem?
Here is what I have done:
Replaced the IAC valve
Cleaned the MAP sensor (no MAF sensor on this engine, that I know of...)
Checked and cleaned the spark plugs
Cleaned all electrical terminals
Checked the resistance in the throttle control sensor
Checked for vaccum leaks with carb cleaner
Cleaned PCV valve (3 times)
Replaced Air filter
Probably a few things I am missing in there, but nothing has been a success.
