Prius (2010-12) :: Metal-on-Metal Whining Sound While Running
Oct 22, 2011
I own a 2010 Toyota Prius that recently developed a metal-on-metal whining scraping sound when moving. It does not make sound when the vehicle is stationary, and it's intermittent - which makes me discount the rock-in-disc-rotor idea (not eliminate it, mind you). It's quite loud when it occurs, able to hear it over the stereo. Luckily I was near work at the time, so I went there - but the shop can't even look at it until Monday evening - so I am a bit panicked.

At 75K my passenger side rear brakes were making metal on metal sound. I was really surprised as I have always learned that the front brakes take 80% of load and they always go out before the backs. So I took the wheel off and sure enough the pads were metal on metal. Changed everything out. (new rotors). I then went over to the driver side rear brake. Looks brand new. The pistons were barely out. I figured this caliper is bad. (I haven't change yet)
When I drive I can hear a very faint metal on metal sound when I brake. VERY FAINT. So with 75K miles on I figure the front brakes are due. Today I took the wheels off and inspected them. Tons of pad left on both of them. If I didn't know better I would say a brake job had been done very recently. (I've owned the car new so I know they have not had a brake job) However after reading many articles on this site I found a thread where one user said he was changing his front brakes for the first time with 110K on them and the pads still had 10K left in them. So the fact that my front pads are still pristine at 75K may not be a big deal (or not as big as I thought. Also I am not hard on brakes.)
However I'm not sure what is going on. Why would the passenger rear brake be metal on metal at 75K and the three other pads are like new. Is the passenger rear the only one working (or working much harder than the others) meaning the other three are bad? Or is the rear passenger bad and the other three are good? I have a working knowledge of cars but I am by no means a mechanic.

I commute 180 miles a day, 6 days a week. I noticed metal on metal grinding noise(more noticeable) at high speed above 75mph especially on asphalt road. I'm sure noise is there at low speed but not enough to notice. My car has 50,000 miles. Tires? Electric motor?

I have a 2011 Prius with about 32K miles on it. I've been hearing light metal on metal grinding noise for a few days now. So I decided to take it to a stealership and they told me my ceramic pads and brake rotors both need to be replaced for all 4 wheels. I thought Prius brakes don't need to be replaced for 100K miles.

I have a 2007 hyundai sonata, this car is my daily driver. I put 180 miles on it a day around trip. Currently has 180,200 miles on it. Last Friday on my trip home when i turned right I heard a metal on metal sound. I slowed down went straight and it went away. Talked to a few people and I think it may be the wheel bearing. Even if I hit a road reflector it starts up. It's the front left wheel. Get on the breaks it goes away.
So my question is... Wheel bearing??? And can I replace the whole hub and fix the problem or do I have to try and press the bearing out?

I have a 2003 Toyota Solara 4 cyl. auto. transmission. I recently had the head replaced. Now it is making a metal on metal sound near the drivers side of the engine. It makes the sound during idle, when I change gears, and the sound increases when I rev the engine. What could it be?

I thought i heard this yesterday when i left work but i was tired and said its in my head, THEN i go to leave right now and sure enough its a real sound, you can hear it very well through the front grill and then if you turn the volume up you can hear a ticking sound ever half a second or so, it also speeds up when i was pulling on the throttle cable. And after the truck fully warms up it goes away.......

My 2011 2.4l Sonata made a metal on metal sound suddenly the other day. About 4 days ago, I drove about 2 hours away from where I live, Mostly highway, about 80mph to a go kart race. Got out of the car for a while and came back in and was pulling away to run the store and as i started to approach the first stop sign maybe 500-600 ft from where i was parked, i heard a bad metal on metal sound, came to a complete stop at the sign and it stopped. Went back to the race after driving to the store about 5 miles away.
Got in the car to leave and same thing, just to the stop sign 500-600ft away. Drove home like i said mostly highway, and didn't hear a thing. Today, about 4 days later, I drove to Chicago O'hare airport, about 30min away, and it was fine the whole way there. However on the way back, after about 20-25min, I heard it again. So I came to complete stop as I was forced to by a traffic light as I was taking my exit off the highway, and It started making that sound again. So i came to a complete stop at the light and started moving again when it turned green and couldn't heard a thing.

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.

I have got this noise which sounds like a light skimming of metal on metal. It sounds like a roller (airport baggage) spinning. It can be heard mostly when driving next to a wall or past parked cars. I suspect it being the bearing in either the water pump, idler pulley or even alternator. The car has 330000 kms but it is serviced regularly in which all fluids have been changed over time. I just want to drive through a tunnel and not hear any non harmonic sounds coming from the front.

I have a 2011 Santa Fe AWD Limited. 90,000 miles. I have a strange sound I need identifying. At first I thought the sound was my AC depressurizing, but it's not that. It sounds similar, but has a faint metal-on-metal jingle sound to it, like something is rubbing or something is rotating and intermittently hitting something just slightly. The mechanic went in to change the water pump because it was leaking, and he thought that the water pump when rotating was rubbing because the rubber ring/gasket was failing, therefore making that sound. Not it. Tired rotated and new brake pads put on. Still there. To be clear, the mechanic never said he heard the sound. I just told him about it.
I can hear the sound when I turn the car on and put it in reverse start backing up. I can hear it when I let off the brake (driving and in park), which lead me to believe that it could have been the pressure in the Master Cylinder or ABS. I don't know now because it does it intermittently when I am driving down the road with no brake applied. When I park, I put the car in Park, get off the brake and just listen. And I can hear it. When it is in park it is more rhythmic, with two or three second breaks in between. kshhh kshhh kshhh kshhh. (I hope you like my poor attempts at sound effects.)
Is it the ABS system? Don't tell me it's transmission related. I just bought this car (used at 87,000 miles) and already had the struts done, the water pump and drive belt done. For what it's worth, this car's passenger and back seats vibrate at 60+. Not sure if that has anything to do with this sound, but thought I would mention it. New struts and tire rotation did nothing.

I have a loose, binding, metal on metal sound on my steering wheel shaft. I have removed the steering wheel, replaced the clockspring, because when I removed wheel clockspring was in pieces and I thought that might be the issue. Guess not, because I'm still having problem. Other than having to remove or replace the whole steering column...

I notice that when I close my door, it actually sounds like metal on metal. Looking closely it doesn't appear to line up well with the latch on the door.

I've been hearing a metal on metal sound coming from the brakes. I checked the pads with the wheel on and they all looked good. The back were replaced before I bought the car back in October. Last night the brake warning light came on, so I brought to my local shop. Longer story short, the inner pad was completely worn out, but the outer's were good.

This morning on my way to work, pulling into the parking lot around 20mph. I hear a metal on metal grinding noise. (almost to the sound of a muffler dragging on the ground type noise). Then that disappears for a bit, hear a loud metal clunk then some high pitched sound. All within say 30 seconds. Definitely coming from the back, but can not tell from which side.
Things I've checked in the parking lot:
Nothing hanging low, exhaust seems in-tact
It doesn't look like the brake shields behind the rotors are bent or touching
Sounds still happening if on or off brakes , on or off throttle.
It seemed to happen only at lower speeds. Disappeared once I got up to 50mph
Just took it out for a drive, that loud metal clunk happened when I put it into reverse, drove around, no other sounds. I just don't have a warm fuzzy feeling that this will just disappear.

My Elantra's HVAC fan has always been a quiet thing, even on 3.....we won't mention level 4 and the fact it sounds like a 747 at takeoff.
I kid you not, the very evening I hit 60,000 miles and the general warranty expired, the blower motor started making noise like it was throwing a bearing and definitely sounded like some light metal-on-metal rubbing. After I became irritated at this, the noise went away and didn't come back until just a few weeks ago. I could make it stop by smacking on the bottom of the fan assembly a few times but I want a more permanent solution.
Tonight I dropped the blower out which was stupid easy except for the fact you're upside down in the dark with your head in a hole. But three screws and an electrical connector later, I dropped the assembly to find no serviceable components. I mentioned this to friend of mine who's into Volvos suggested spraying some lithium grease on the hub of the blower and letting it run long enough to quiet it down. I'll do this over the next few days and report back but part of me thinks a new blower may be in my future.

I have a 2012 Elantra with 21000 miles on it. It runs well but in the last month or so it has started to make a strange noise when first accelerating. I would describe the noise as touching a fork to a metal fan...kind a "zzziiiinnnkkkk" sound, I guess. It only happens when the car has been sitting for a while and only on the first acceleration, usually in first, second, and third gear after which it immediately goes away and doesn't happen again until the next time we drive it. It seems like it would be related to the transmission except the sound is too tinny for it to be the gears. It sounds more like sheet metal making that sound. I took it to the dealer but they said they couldn't make it make the sound, which is crazy because it does it EVERY time we drive it.

About 2 weeks ago, my 2004 Honda CR-V (176K miles, manual transmission) started making sort of a dry, whistling, whining sound. It's not a grinding sound but more like wind whistling through something metal...? I think it's coming from the right back wheel or wheel area. It doesn't start until I've been driving maybe 6 or 7 minutes, and usually kicks in above 40 MPH although I've heard it when going slower, too. If I jiggle the steering wheel the sound stops and starts. It also stops when I go around curves or make turns. At first it was happening all the time, but over the weekend it seemed to be diminishing.
I did record the sound on my phone and uploaded the video to the following link: [URL] .... You can hear it stop at about 16 seconds and then start again at 20. Also, starting at 35 seconds I stop for a light and then restart at about 1:10. So you can see how it kicks in as I start going faster. No jokes about my shifting or driving or the dog panting in the background. I'm sure the vid will go viral.
I took it to a mechanic Monday but he only heard it for about 3-4 seconds. He put the car on the lift and inspected the wheels but didn't see anything obvious so is chalking it up to old car syndrome. So, do I seek a second opinion? Is this something obvious for CRVs? I just want to make sure the bearings (or something like that) aren't going on it.

I recently worked on a 2006 with 140K miles that presented with the following symptoms:
The hybrid battery was at 1 bar; the ICE would not start; the car was in Ready, but there were no codes. As I let it roll off the flatbed wrecker in Neutral, it felt lumpy. If you have ever pushed a car (or run out of gas in one) with a manual transmission that was in a high gear, engine off, it felt just like that.
I popped the hood and could see that the engine crank was turning while the car was being pushed in Neutral. What else turns with the wheels? MG2, or more specifically, the MG2 ring gear. What is the only way that the wheels could turn the ICE crank? The planetary carrier pinions were locked to the ring gear.
Surprisingly, while I was looking at things, it did manage to start the ICE pushing it around must have freed the carrier pinions, so I let it charge the hybrid battery. It was basically the worst metal-to-metal noise that I have ever heard! I pulled the drain plug and saw about a teaspoonful of large metal chips on the magnet. The fluid condition itself was very good, not the black factory fill that I am used to seeing come out.

I have a question about my C Four with 16" wheels. When the steering wheel goes all the way to a stop there is a thunk that feels like metal on metal. It is like there is no rubber bump stops. If this is normal. I am used to cars that have a nice cushioned bump at the steering limits.

I have noticed an odd sound when coming to a stop. It sounds like a metal ball or two rolling forward when I brake then roll back and hit something when i come to a complete stop. At first i thought it was just something rolling around in the center console but I haven't found anything. What is under the center console/drivers seat that may have something that could roll like that?
