I had a super loud metallic scraping and clanking noise when I was backing out of my driveway the other night. It was so loud I though my exhaust was dragging or something.
It turned out to be a rock trapped between the heat shield and rear brake disk. I pressed the heat shield away from the disk a bit and the rock fell out. It's kind of crazy that such a little rock caused such a loud sound.
So I started getting this metallic/harmonic whining sound from my GTI's engine a few weeks ago. It was barely noticeable then, but has now gotten louder and more consistent. The sound occurs once the engine has warmed up and can be reproduced by holding the revs constant anywhere above 2k. The sound does not change in pitch with engine speed. It doesn't matter if the car is parked or moving.
I've attached a video... The sound can heard starting at 00:23 and becomes constant after a few seconds. Its hard to hear at first, but if you listen carefully its definitely there.
I have an appointment with the dealer tomorrow and will update with their findings. In the meantime, any clue as to what this could be? I can't really pinpoint where its coming from, seems loudest near where the oil filter is? By the way I'm 100% stock.
I noticed that the driver side front wheel makes a metallic scraping noise while the car is turning right. It sounds like something scraping the rotor or shield behind the rotor ( a rotational/moving kind of scraping noise)
This only happens on a relatively sharp turn (wheel is turned 70~80% to the right). I don't suspect the power steering as there is no noise if the car is not moving even when wheel is turned to extremes. The scraping noise happens at any speed, as long as the car is moving. does not happen when car is turning left.
Note that I am 90% certain it is from the front... my ears may be playing a trick on me (kind of hard to listen precisely while driving). Where to start looking?
Was about three blocks from home when the front of the car started making a horrific metallic scraping sound as the front wheel turned. I mean LOUD. Did a quick look for something stuck in the wheels somewhere but nothing. It's not like a branch stuck in the wheel sound, but scraping a shovel on a steel beam kind of sound. Braking seems to change the makeup of the sound, but did not stop it. Parked it in the garage.
I pulled the left wheel off, looked and looked, and looked. Nothing. Fear and sadness setting in. Everything looked normal....except....a faint line on the rotor very near the inside edge. Got a mirror and looked some more, and there, wedged on the inside edge of the pad's metal part and the rotor, was a rock the size of a bb. At most. Got a small screwdriver and hammer and popped it out. Done. Sheesh.
Seriously it was so loud it was amazing. So store in file folder for future reference if needed.
The line can be felt barely with a fingernail and is half the width of a pencil lead, and goes under the innermost 1/8" of the pad. I'm thinking do I want the dealer to pull and turn it, or is it going to affect my braking at all. Pretty much gonna leave it be I think.
My R32 has got about 9,400mi on it, and for the past 3k miles or so, i've been dealing with this metallic scraping/rattling noise coming from underneath the car. When I took it to the dealer, they said it was the exhaust flex pipe, so they replaced it under warranty. Next day after picking the car up, same noise. So i took it in again this morning and they are saying its the flex pipe again, and they don't know if it is fixable.
They are talking to VW tech assistance, and trying to figure something out. I really love this car, but if VW says there is no fix for it, I'm weary about possible future issues without fixes too. Apparently it has something to do with the length of the flex pipes and the material its made out of. He was saying one possible solution is stiffer engine mounts. We'll see where this goes.
I picked my R up three weeks ago tomorrow. I took it in this morning because there has been brake noise from day one. The noise was a scraping, metal on metal sound that diminished a fair amount when the brakes were warm. I only got a very brief conversation with the service agent at the dealership this afternoon, and all he told me is that they had to order in new brakes. I don't know if it's just pads, or calipers or rotors or the whole deal! I'll get the whole scoop tomorrow.
View 5 RepliesI just bought this camry recently, it's an 2008 SE 4-cylinder with about 95k on it. Everything is fine on the car with the exception of one thing. Whenever I start it after a prolonged period of it being off, say in the morning or sometimes even having it off for an hour and then starting it again, when I start it, a loud grinding/scrapping noise comes from the front of the car.
This noise lasts for a good 30-60 seconds and as the car picks up speed it disappears. It just happens whenever I start it. Now I'm not sure that if the brakes or jammed or is it something to do with the transmission. I mention the transmission because during the drive, the car seems under a lot of pressure as if towing a large trailer and has trouble accelerating. At times when going downhill, it actually is slowing down as opposed to picking up speed and as soon as I let off the gas the speed drop from significantly.
I know this isn't normal because I used to an 2005 Camry LE 4-cylinder. So I know how the engine and transmission behave.
I took it the dealer recommended mechanic and he said that everything is fine. He's a nincompoop really. I took it to my mechanic and he said that the axle and bearing need to be changed on the passenger side and just the axle on the drivers side. My mechanic is a family friend and is skilled in his trade so I know he's not trying to shaft me.
In February 2014 I purchased a 2011 Honda CRV. I often travel and am gone for about a week. Every time I come back the rear brake are rusted. They have a loud thumping and grinding sound. I immediately took the car back to Honda dealership (2 time) both times they 'shaved' the roaters. I then contacted Honda headquarters to report the issue. They told me to deal with the dealership and take it to a local mechanic for other opinions. Car Talk will be my second opinion. Honda dealership told me that this is just the way it is. This is my third Honda, I have NOT had this problem before.

View 3 RepliesI have a 2004 F150 4x4 Fx4 supercrew with 5.4 engine and 46,000 miles. For the past three weeks now I have a periodic Grinding /scraping sound that seems to be coming from the front passenger's side of the truck. It can come on with light driving and braking in town or start while driving 70 mph down the interstate without even touching my brakes. The thing is I just about always have to come to a complete stop to make it go away. 10 Minutes later it comes again. It's loud enough for everyone around me to start staring at my truck. Sounds like metal scraping concrete and gets deeper as I slow down and when I fully press my brake pedal it goes "curchunk and the sound is gone for a while. I thought maybe my caliper was sticking or maybe the truck is trying to go into 4x4. One friend even suggested me to check the dust cover behind the brake for rocks.
View 12 RepliesRecently my 2001 Solara started emitting a scraping noise from one of the rear wheels. Mechanic says its a frozen caliper, and suggested a complete brake job (rotar, pads, etc). My question is, I've got reasonable skills, by buddy has major skills when it comes to working on cars, is that something that a shade-tree mechanic can safely do ? Also, as its a frozen caliper, does that imply I need to replace the caliper, or could it have frozen due to the pads ?
View 5 RepliesOur 2010 Prius makes a loud metallic slapping sound whenever we drive over the lane marking reflectors on the roads.
Audio recording included....
70's Ford 4x4 truck. I'm getting a very noticeable --- but intermittent, doesn't happen every time -- metallic scraping sound when turning right at slow speeds. Coming from the rear of the vehicle. Like in neighborhood driving. No unusual sounds when going straight. For the past week the problem seems to have gone away, so I'm playing this one by ear. Hopefully whatever it was has gone away. But I'm ever the worrier.
when it happens, it sounds like if I dragged a big sheet of metal on the road behind the truck. I'm sort of suspicious this sound is from the rear limited-slip differential. Could it be the diff clutches are corroded? Coming loose from their moorings? A differential bearing on the fritz?
Problem 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....
Noticed this morning that my Honda Civic is making a metallic scraping noise while moving -- happens when not braking. Appears to be coming from the left front. I noticed it at very low speeds. It isn't exactly the "wah-wah-wah" grinding sound that changes a little in pitch as the wheel rotates that I'd expect from a bearing. I've been through a bunch of Youtube videos from people diagnosing various wheel- and brake-related problems and haven't found one that matches mine yet.
View 3 RepliesI have an issue with my 2011 350 that is quite perplexing. I get an intermittent sound... best I can describe it is like a metallic vacuum sound that seems to come from the right rear of the car. There is no pattern to when it arises... comes and goes. I've been to the dealership with it 3 times and of course it did not occur. They must think I am hallucinating. I thought it might be an exhaust problem.
View 6 RepliesSo... I bought Ksport Coilovers and had them installed about a month ago. Were on the car about a week and started to get creaking noises from the front. So, I contacted BSH (who sold them) who put me in contact with the Director of Operations for Ksport...
Send them to him, and he replies that he thinks my sway bar is high, and that it should be "parallel with the ground. Today when backing up (down right) I get a horrible scraping grinding sound. I stop, get out (thinking it is the fender liner) only to find no damage. So I keep checking and find a fresh scrape on the axle. I drive (gingerly) home and pull the wheels off and check everything in the front. It is all tight and nothing seems to be broken. I look at the sway bar end (which is curved).
So was driving home from work today and was fairly close to home waiting at a light. Light turns green and I start to move forward (going up a moderate hill). I shift into 2nd and all of the sudden I hear a loud, metallic "rat-tat-tat" coming from somewhere around the passenger side front area of the car. Almost like a snare drum but more metallic sounding. Then this is followed by what sounds like a second or two of metal-on-metal type grinding noise. Don't feel much of anything, maybe a slight shudder. Then it seemed fine.
I was only about two blocks from home and it was driving okay so I continued on home. No warning indicators of any kind on the dash. When I got home I looked in the engine compartment and under the car for any signs of something obvious being broken. Nothing. I haven't driven the car since but I'm worried about what might transpire in the morning. It's even possible that it was one of the cars next to me and I was hearing the sound from their coming nightmare echoing off of the buildings to my right. But, it seemed like it was coming from my car, and that metallic popping sound has me very nervous. But as I said I drove it a few blocks after this and it seemed fine.
When my car is cold... sitting 8 hours below freezing I've noticed until the car warms up I hear almost like a quick scraping sound when I take off from a stop or when shifting. It's almost like when the engine is put under load the movement causes something to shift and makes this noise. Any chance I have a loose mount or a portion of the exhaust could be shifting coming in contact with something?
View 13 RepliesI traded my 08 R32 for a certified 2013 GTI Autobahn 4 dr. and have noticed a few quirks or issues. I have had several Vw's and my wife currently has a 2010 Tiguan SEL awd. The car goes in on the 10th to see what the dealer can find out. I bought the car with roughly 9400 miles and it has 11,300 on it now.
Issue 1 - The passenger side door handle does not pull smoothly to open. When you pull on it it goes about half way and stops and then you have to pull it again or harder. I am thinking it is an alignment issue.
Issue 2 - When i first start driving after the car has sat overnight in the garage or in the parking lot at work I get a swirling sound from the rear brakes. I do set the parking brake every time it is parked. It is almost like the brakes are not releasing all the way or rub for a little.
Issue 3 - This is the one that is odd and concerns me. When i first start driving the car takes several minutes to come up to 190 degrees. I baby the car till it gets up to temp for the turbos sake. But oddly after it gets up to temp with in 5 minutes it is like the thermostat opens and it cools back down to 150-160 and then comes back up to temp. My wife's car does not do this and neither did the 07 Passat 2.0t. Is this common? When talking to the service advisor (who I have been dealing with for a while) he said he has never had this issue come up.
I have an '09 Camry and for the last few months have been hearing a metal popping sound in the rear wheel area when I go over a bump or pothole unevenly or backout of a driveway at an angle to go onto the street. The sound does not occur when the wheels when they are even, only when the rear right wheel is "lower" than the left. It has not been in any accidents and there was no event that preceded this popping. I took it to the dealership but they were unable to replicate the issue but it happens no matter who drives the car (my husband or myself) and it is likely that the service guys didn't go over any bumps/curbs/potholes unevenly to hear the sound. They check the axles and said everything was good with the car but it is still popping and driving me nuts.
Current suggestions:
• Cracked bearing race. It could be another problem entirely having to do with the suspension mounts or axle mounts but let's hope these new mechanics will figure it out.
• Problem with a wheel bearing
• Struts and suspension components
• Bushings and parts
• Loose upper strut center nut or from loose upper strut mounting nuts
I took it back to a shop but they are thinking the sound is actually coming from the body near the roofing area in the right rear portion of the car. They seem to think based on the sound (metal popping only when that wheel is lower (like coming out of a driveway angled, or going over a pothole)) that it is the metal body but it would cost and arm and a leg to get in to even find out what it was. They assured me that it wasn't impacting the safety of the body and is just a funky sound. The sound is much louder in the car than outside which I think kind of supports their theory. Are they right and it won't impact the safety?
