Sonata I45 (YF - 2011+) :: Metal Grinding Noise When Braking?
Oct 14, 2015
My car is making metal grinding noise when coming to a slow stop when you are stuck on traffic or going into your driveway. You can hear the sound and feel the sound.
I had this issue a year go and i took it to the dealer and they told me that i need to replace my rotors and my front brake pads.
A year later the noise came back and they told me that i need to replace my pads. I replaced my front break pads and a month later the noise is back. I went back and checked my pads and the pads were still new.
I only hear the sound when braking after driving in a heavy traffic or on a stop and go traffic. I don't hear the sound when i start to drive or driving in a non traffic condition.

I've read a few posts about the Prius braking system. Just wondering what other owners have done when they experience the metal grinding noise and when brakes need to be replaced. My car has around 67,000 miles. I was planning to take it to a Toyota dealer, although prefer to find a certified Prius or hybrid mechanic at an independent shop.

I replace my brake pads and rotors in the fall of 2015 with EBC parts. Now almost 13,000 miles later, I started hearing grinding and metal-on-metal contact in the front. So I went out and got PowerStop pads to replace the EBC (EBC had way too much brake dust). I took off the front wheels and noticed that the DF pads had about 1/32 left on them, ok I guess its time to change them out. Onto the PF pads, I find that there is almost no material left, in fact I could scrap off what was left of the material. I decided to do a rotation while I am at it and noticed that the rear brake pads on both sides look like I never used them!! Is it really that possible to have 2 stuck calipers, both on the rear at the same time?

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 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 an '02 Taurus. For the last year or so it has intermittently produced a metal on metal grinding noise while failing to start up. I'm told this is due to teeth being missing on the flywheel between the starter and the transmission. It's taken as many as six tries to get the car going. But the car has always started in the end.
My questions are: Is the problem flywheel worth replacing at this point at this price? Is it likely to fail totally any time soon?
Also, might the March '09 replacement starter be implicated?

I have intermittent metal on metal grinding noise. Seems to happen when I am at highway speed. Seems to go away when I put it on 4 wheel drive or slow way down. On one occasion though, the grinding noise did not stop even after putting on 4 wheel drive - had to stop completely before it went away (did not come back after I drove off again). Diagnostics so far....
Unhooked the vacuum lines on passenger side actuator and hooked up vacuum gauge. Vacuum held at 20 psi and drops and raises slightly as the truck is being revved. Takes about 10 seconds for vacuum to drop to zero once truck is stopped. Putting it on 4 wheel drive drops it to zero immediately. Exact same scenario on the passenger side.
This leads me to believe my IWE solenoid is ok. So also my check valves. Next opportunity I get, I will raise one wheel, remove the vacuum line on that wheel and apply vacuum with my pump. Want to see if it will turn my half shaft.

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.

So for a couple months now, my ride has been making some weird noises.
When I start the car up after anything longer than a couple hours of use, it sounds as if I have a piece of loose metal banging/moving around. I hear it sporadically on shifting through the gears, and when I'm at a stop.
Car has been in to the dealer three times, and I took the foreman on a test drive...of course it wouldn't make the sound at all.
I took a look under the hood today and noticed that the coolant level is low...filling it back up tomorrow. That got me thinking about the transmission fluid....I looked and looked, and can't find the transmission dipstick anywhere.
Any clue where I can find some way to check the level?

I have 2003 F150 SuperCrew 5.4L XLT. For past month or so, have been hearing metal rubbing sound and had shakes in braking - as well as a "grabbing and pulling" sound near brake pedal - very aggravating to say the least. Weird thing is the grabbing and pulling sound only happens under 10 miles an hour or coming to a complete stop. (The grabbing sort of sounds like the sound the ABS makes when hit really hard)
Yesterday I had brakes and rotors replaced - mechanic said front rotors were beyond turning - very bad. 135,000 miles on truck. Felt more comfortable until I pulled out of shop and when I applied brakes, had the same grabbing/grinding sound, but no pulling. Went back to mechanic and had him ride with me to hear sound, and he is stumped.
Knew it was safe(r) to drive since new pads/rotors installed, but when I got up to 55mph and barely touched the brakes, the steering wheel began to shake violently - but no sound/grabbing from brake pedal area like I get when I am 10mph or under. Really at a loss right now.. What's going on?
Truck is a 2WD, also hear some thump thump thump sounds from front left tire, which are only one year old, but tire man said that was from suspension arm or something - nothing to worry about he says.
Some people have said "bearing" or "hub" but when brakes were replaced, the bearings were repacked...is this the same thing? Is the current problem safe to drive with? I do not take vehicle out of the county - just to work and back and hunting on weekends.

I purchased a 2011 Sonata Limited Edition TODAY. It was a lucky find as the car has less than 30k miles. As I was driving home (back roads and interstate), I heard a clicking noise every time I hit the brakes. I do not hear this noise when I back up and brake, only when the car is in drive and I am braking.

I got some coilovers installed last night, they are ksports. i have them on fairly low height as of now but i have noticed every time I hit bumps, I hear a kthunk (metal hitting metal noise) from my front driver side. is it from the coilover nuts itself or something wrong with my control arm? the sound ONLY comes from the front DRIVER side.

I changed my tires, brakes and rotors last August. I had installed EBC YellowStuff. I also greased(using SilGlyde) the slide pins and bled the brakes.
Last weekend, my car was making a weird noise when I hit the brake, so I removed the front tires and noticed that the front passenger side outer brake pad was completely gone and the inner brake pad still had 25% life left, but it was tapered(image attached).
I know when this happens, usually it means that the slide pins need to be greased, but they were plenty greased from my last year's brake change. I still greased them, but now I hear grinding noise frequently(not all the time) when I am accelerating at slow speed and sometimes at even high speeds.
There is no fluid leaking and I could only see surface rust on the pistons. Its driving me crazy, because I can't figure out what it is. I am thinking of just replacing the slide pins anyway to be on the safe side.

I have a 2011 Sonata with 4,000 miles. Recently, I have noticed that when coming to a stop, I hear a light thump noise in the center console area near the gear shift lever. If I put my hand on the gear shifter, I can feel it move ever so slightly at the time of the noise. The noise is very repeatable. If I take my foot off the brake and start rolling and then I reapply the brake (either softly or hard) it will make the thump noise. It is not very loud and can be drowned out with loud music, but if listening to news, it is very noticeable and annoying in city traffic, where stops are very frequent. I put the car up on ramps and looked underneath and did not see anything noticeable. It will probably require the center console between the seats to be removed.

Honda Accord 2005 ... Just bought a new used car. All seems ok, but I have two problems.
(1) when not moving, i have slop in the steering and I can hear metal on metal contact when I turn the steering wheel. I pulled the tire and with basically no force I can move the rotor back and forth by hand. what it is and how to fix it?
(2) when braking, it appears that the front left pad sticks. Pads are not excessively worn down. Can't figure out how to get to the caliper pins ( thought they might be sticking).
Could the two be related?

Ok so 11 days into ownership and only slightly over 800 miles the car started to act funny. First the common DVD nav issue (no disk in drive message).
Second issue is a strange metal on metal rubbing noise when turning at low speeds (i.e. in parking lots). When I make a big turn (either direction) it sounds like either the brake calipers aren't releasing fully and is causing the pad and disk to rub, or something else is rubbing.
This actually happened once yesterday on the highway as well. going 75mph, a very loud metal on metal rubbing noise.
Seems to only happen when temps outside are below 40. It warmed up yesterday afternoon and the noise went away, but after it got cold again last night, the noise came back.

For the last week or so been noticing as I'm slowing down, brake or no brake, a metallic, grinding noise coming from the rear passenger side. Does not sound like a humming worn wheel bearing noise. Its pretty loud, almost clunky and not always consistant. Then the last day or so have noticed it on the right side. At higher speeds....faintly hear a ticking... The car has 48K on it.

I read here somewhere you should NOT use caliper pin grease or any other grease for that matter on the pad sliders; either on the bad or the cup itself. I think it was Smoke. I have been doing this for quite a while and need to know why it should not be done?

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.

I have a 2006 Elantra 4 cylinder with only 55,000 miles put on it.
Whenever I accelerate I hear this noise that sounds like a lawn lower under my hood, usually only there until around 45 MPH, then it dies down a bit. It as been getting louder and more....... screechy..... as of late.
Also, when idle, there is a sound that almost sounds like a metal grinding chugging noise. It comes and goes with no real rhythm or timing.
Additionally, there is a metal grinding noise coming from what seems to be my front right wheel area when I make wide right turns, as well as intermittently while driving regularly.
To my knowledge, neither of the motion noises seem to be happening above 45-55 MPH, or they are too soft to hear at those speeds.

Youtube video below, listen to the sound at 0.09 sec, 0.14sec and 0.20sec (ignore rest of the sounds they are from golf balls that I have in the bottle holders). When i turn the steering to the extreme right i hear this sound like pulling a metal. What is the issue and how serious is the problem.
I have 74,000 miles on it. 2011 Hyundai Sonata SE 2.4L ...
