Elantra XD (2001-06) :: Loud Rattling Noise From Under The Car
May 25, 2011
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!!!!.

I'm having an issue with my 2004 Elantra.
When I turn the ignition in my car, it makes a very loud noise at the front of the car. This goes away after about 3 seconds, but when I turn the wheel to either side, it makes a very high screeching sound. This persists until I've been driving for a few minutes then it goes away.
I hesitate to say the following, but it also feels as if my steering wheel is a bit "harder" to turn, but maybe it is my imagination. What it could be? I checked power steering fluid and it is at normal levels.

Having problem with my car (2001 Elantra GT) - over the last month or so it's been occasionally making a very loud (not but consistent) grinding noise coming from the front of the car when decelerating at low speeds. The noise sounds like gears slipping over each other but cuts in and out. It's pretty loud and not a nice noise to hear! Sometimes it makes the noise when I brake firmy but not until I reach lower speeds... mostly it's just when coming to a stop, but it did it once last week when I was pulling very slowly out of a parking spot and not even braking.
As it's become more frequent (going form maybe once a week to several times every car journey) I have started to feel something in the brake pedal also, like there's something kicking it from behind. I took it to a mechanic and had to pay a ton of money to get a broken front left ABS ring replaced (it also had the front right ring replaced in May), and within 2 minutes of driving away from the place the noise was back. Before I spend even more money that I don't have on taking it back for extra diagnosis.
I'm told that this is almost certainly the ABS system that has a fault even though the ABS light never shows except when I start the car, and I've taken the fuses out of the ABS in order to confirm that it is. I haven't heard the noise after a few days of driving with ABS unplugged so I think we can be reasonably sure here. Is there anything that I can check myself or test (I'm not very handy when it comes to cars) or can you tell from this information what it's likely to be? Other things that I've noticed with the car which may or may not be relevant are:
- the warning lights for brakes, ABS and TCS are all lit with the fuses for ABS1 and ABS2 taken out. I take it this is normal for all 3 to illuminate with the fuses out?
- since unplugging the ABS I've noticed a slight metallic squeal from the brakes as if the brakes are worn down. Didn't notice this before I unplugged ABS though it may have been there, not sure.
- sometimes when going over a speed bump or just a minor imperfection in the road I hear a clunk in the front of the car and feel something move in the underside of the car. Happens mostly at lower speeds also, but not if I go over the bump really slowly.
- in the fuse box when I took out the ABS fuses I noticed there was a bit of minor melting/brown burn marks on the top of the connections marked (iirc) ECO3 and ECO4 on the diagram (large white connectors). Is this anything to be concerned about?
- sometimes when I have air coming into the car through the air vents it will become significantly warmer for a few minutes, then slowly go back to normal. Can't think of any circumstance that links the times when this happens (eg. speed, weather etc).
- the oil pan has a leak which is on the list of things to fix when the car works properly.

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.

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.
Milage: 177,000
Current Codes:
P0422 (catalyst 2 efficiency below threshold bank 1)
U0D00 (What that is)

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?

Getting a loud rattling noise from the front of car in Park or Neutral? As soon as I put the car in D/M. I have heard that the transmission is noisy in neutral, but just want to double check.

So, I was driving down the road one day at like 50mph or so and had the loudest backfire I've ever heard. As I was putting my car on the dolly to tow home I heard a bunch of rattling and thought maybe it was a rod bearing or something. I pulled the oil pan and found chunks of my upper chain guide (rod bearings were fine).
I replaced the chain guide and checked the timing hoping it would fix the problem, but it didn't. The rattling was gone but I was only running on 3 cylinders. Did a compression check and had 0 compression in Cyl5 and about 60-70 in Cyl2. I don't remember exactly what the compression was for the other cylinders since it was a while ago.
Started thinking it was bent valves, so I just recently pulled the head off to check them. They all looked like they were seating properly and none looked bent from what I could tell. I'm about to try to put some compressed air through it to see if the valves are leaking anywhere. the plugs, wires, and coilpack are all functioning properly.

i have an 07 jeep compass (only 52k miles). it was making a loud rattling noise (i liken the sound to the noise a penny or pebble makes when its sucked up a vacuum). I pulled off for gas last night and it just wouldn't turn back on. AAA was able to jump the battery and i was able to drive home. Now its dead again. i previously had an issue where the car was stalling when idle (only if it was in drive). I'm thinking the rattling, battery draining and stalling must all be connected.

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.

When driving there is a loud rattling noise coming from the exterior of the car but when I put on the brakes the noise stops. I'm not sure if its a brake shoe or some other cause...

Was driving 97 honda Accord 4 cylinder today when it made a loud rattling noise, took it in to advanced auto parts to see if they could give me a hint to what was wrong, as I was showing the employee the noise got progressively worse and he told me the connecting rod was loose and I could make it home if I went under 35 he mentioned something about tightening two bolts but having to drop the oil pan to get to it, as I was driving home the noise eventually turned into a clunk and the car died, when I try to start it up you can hear the engine turn but there is nothing after that, don't know much about cars but what is the process I need to go through to replace this connecting rod myself and how to get the car to start again.

I got in the car today and started it... I was waiting a few seconds for someone to get in the car (it was in the garage) and as soon as the engine kicked on there was a very very large long rattle noise i immediately turned the car off. Waited again and turned it on same noise.. the only thing I found was a cover under the car towards the front was really loose. ( I haven't hit bottom or anything while driving) but I did have the lighted door sills just installed the other day. But it never made that noise..
btw i have 1100 miles on it..I looked under it and is the black dust protector thing supposed to be loose like if I push on it I can make it rattle..

Fiance's 09 Corolla S just started having a rattle/knock noise this evening. car has 123k. It's clearly an engine internal sound. I believe it is coming from the cylinder head. She called me when it started making the noise, she shut it off and has only been ran enough to get it on and off the trailer.
Not sure if it's a broken valve spring or valve. or the timing chain guides? It threw a CEL light.
I ran the code on my scanner and it came back with: P0302 (Cylinder 2 Misfire)

Our 1995 Toyota Camry shakes and makes a loud rattling noise while driving, but not every time I drive the car. The rear seat of the vehicle, especially feels the shake. The rear tires have been replaced and aligned, but still the shake/noise persists. Our mechanic has not been able to recreate the noise. It has occurred in the winter and summer with or without the heater and/or air conditioning on or off. Sometimes the shaking is so severe, I am afraid of what will happen, but I will stop at the next light, sit for a minute or two, and when the light turns green, the car goes, no shaking involved - everything is fine. I typically drive in town so speed is only 45 mph or less. The car has only 137,000 miles, and is well-maintained.

I drive a 1998 Civic hatchback. Last night while I was driving I needed some gas. I pulled into a station and the only gas they had available was 93 (highest octane). I only ever fill up with 87 or whatever the lowest grade is, so I put 2 gallons in to get me to my destination and the opportunity to find another gas station. Shortly after, I was back on the highway and the engine starts making a loud rattling pinging noise when I step on the gas. I normally might have a low rattle or ping that I've never been able to get rid of, but never loud like this.
Then a few things happened– smoke starts coming out the exhaust, the check engine light comes on, and the car starts to overheat. Seems like it was pretty much all at once, although it was in that order that I noticed... I rolled the windows down and turn the heat on high, but the air coming through the system wasn't at all hot. I got off the highway and as I downshifted, the engine started to smoke a little. I get to the end of the off-ramp and the engine dies. It wouldn't start back up right away but I managed to start it a couple of times (between it dying) to get it to coast into a parking lot. Under the hood, there was coolant everywhere it seemed, but I couldn't see anything else apparently wrong– hoses, etc.
In the end I had AAA tow it home. So, what happened and what I'm looking at now in terms of repairs? I will need to have it towed again to a mechanic if it is something I can't figure out myself.

My '06 Nissan Altima suddenly started making a very loud rattling noise as soon as I put it into drive and start moving at low speeds. The noise does not go away at high speeds. It sounds like I am dragging the entire undercarriage. When breaking it grinds very loudly. All of this is sudden. Only other issue I had recently was that the motor wouldn't catch when I tried it Saturday, but it finally did after giving it a good amount of fuel. Drove it 300 miles yesterday without a problem. Woke up to a car that sounds an awful lot like a plane.

So i'm only a week and a half into owning my Elantra, 800km on it and today when i started the engine i noticed a clicking/rattling sound, like the noise when someone sticks a piece of paper into a fan. Anyway it's quite minimal and you could hear it louder when you accelerate. I never noticed it before, even when i test drove the vehicle.

Several times when I started my 2014 Elantra I herd a lot of rattling just like a diesel that lasted around 5 min. I recorded the sound and took car to the nearest dealer in about 100 miles. Two times I left over night so they could hear the sound in AM on first start up. But of course it didn't do it for them and they said they could not diagnose but they did hear clicking noise. When I played the recording said sounds just like a diesel. That's it they did nothing. Now it doesn't sound quite so bad just rattling and clicking. It only 40k miles and still under warranty to 60k. What should I do? Next nearest dealer is about 100 miles. I thought about trading it but I do like the car.

A few months before warranty expired on my 2009 Elantra I began hearing squeaking noise from clutch (it is 5 speed manual). Three trips to dealer and finally they opened clutch to find bearing being dry and plate dirty - bearing lost seal and all grease leaked.
It was about 50k miles on ODO. Plate, bearing and disk (I said replace it since you are there - I paid for the disk) were installed new. All supposed to be fine... until I got home. Here is what happening.
Fork is "swinging". It does not simply seat in position when released, but you can see it moving.
Clutch - when idle speed, clutch released in neutral there is a loud rattling/grinding noise.
Now, diagnosis at the dealer. They put the car on hoist and claim the tranny is trashed as the wheels were spinning when car was off the ground with engine running and tranny in neutral.
The shaky fork - all car is shaking so this is normal - vibration from engine. Replace tranny and it should be good.
