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.
View 3 RepliesMy 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 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?
View 7 RepliesI 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.
View 7 RepliesI 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.
2004 F150 FX4 ....
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.
The topic is as much as I can say to what my car's problem is.
2010 Prius II with 50k miles now.
Bought my Prius (2005, with 160K miles) about a month ago and since I've had it I am hearing a metal on metal grinding noise when braking at low speed. How loud the sound is depends on how hard I am on pushing on the brakes. One of my co-workers has the same model and said that his does not make that sound. Not sure if its just because it has after-market brake pads or something? This noise only occurs when braking at low speeds (below 10 MPH) so I assume its an issue with the front brakes.
Is this something I need to get looked at by the dealership? I had a local mechanic that worked on my old Honda beater take a look and he said that the rotors and brake pads looked new and wasn't sure why they'd make noise.
So my dealer diagnosed my 2007 Prius with a transaxle issue, but what bothers me is that it doesn't make the sound all the time. When I brake lightly, there is no sound and when I brake heavily there isn't either. It is only when I do a medium brake above 7 mph of course and around 20's mph range. I am hoping for something besides the transaxle...maybe a wheel bearing...anything.
View 19 RepliesI may be worrying over nothing but lately when I brake or accelerate I hear a grinding noise on my radio. I listen to AM. With my other vehicle it usually meant there was a problem somewhere.
View 1 RepliesMy car was making a weird grinding noise when braking above 7mph. I did the neutral brake thing and seems to go away sometimes. The dealership said it needed new rotors and brakes, so I went ahead and did that with them, then called me to let me know the sound did not go away. Now they are stating my grinding noise is coming from the "inverter generator" which is what they said was the transmission. I am just curious why this goes away sometimes and if it's related to my previous issues with the car.
View 1 RepliesJust purchased a used 2008 prius with 80,000 miles on it. Braking system makes slight grinding noises when getting below around 10mph. I know the brakes are different, so I'm not sure if this is normal or if it means my brake pads need replacing? Car didn't come with an owners manual .
View 6 RepliesHonda 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?
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 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?
View 2 RepliesOk 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.
View 2 RepliesThis 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.
I am having several issues. I got the lexus dealership to service my transmission recently. I got it back with a weird smell. It smells like body odor. I had to reach out to hendrick corporate for them to address the problem without charging me. Turns out it was the fluid they used. I could smell the smell from inside if i wasn't recirculating the air. They changed the fluid again and it still smells. Is my transmission doing this because it is too hot?
This smell was never an issue until after the first transmission service. And now I'm hearing a metal grinding sound in 2nd gear past 4600 rpm. It still shifts smooth but 2nd gear might be slipping. Something just doesn't seem right. o yea they gave me my car back with my brakes sticking after stopping in traffic. I took it back and was told my brake pads in the rear lost 2mm in less than 650 miles.
By the way this sound can be heard in 1st but is more prevalent in 2nd. It is not heard in any other gears. And when in sport mode the sound instantly stops when i shift up into 3rd.
