Prius (2010-12) :: Horrendous Squealing / Scraping Noise When Started Moving?
Nov 10, 2015
Our Prius is only a year old with less than 9,000 miles. Everything has been fine with it and then yesterday I took it out of the garage and started to drive and there was the most horrendous grinding/squealing/scraping noise as I started moving from the front passenger side (UK passenger, so left looking out).
I stopped the car and had a look, as at first I thought I was dragging something, but nothing to be seen. Checked the parking brake was definitely not engaged. I then thought perhaps something is caught in the brake pads and it will go in a bit, however even hard braking didn't seem to change the noise at all.
Carried on (I was going about 7 miles), and as I drove it would gradually get quieter, and then get louder again, with the occasional "clang" sound almost like a spring under tension suddenly moving.
Towards the end of the journey it had started to go quieter again, but with the window down you could still hear constant squeal/grind.
Parked the car, was away for an hour, came back and set off home and the noise was totally gone. Entirely silent all the way back home! Now I don't know what to do - whether it will come back, or whether I should take it in to garage for them to look (even though it's now not making any noise).

I have a horrendous squealing noise coming from one of my rear wheels. Sounds bad at low speeds, changes frequency to higher pitch when going faster. The sound isn't constant (some times nothing), other times loud as hell. Sometimes gets worse when turning, then nothing when straightened out. When breaking, sometimes the sound gets worse, then goes away. It doesn't sound like a bad wheel bearing (had one go before- more of a growly noise). This sound is too high pitched. Also, checked the brake pads (plenty of life left), and rotors are good too.

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.

So I put in new rotors and pads and everytime the car is backing up I get a weird grinding or squealing noise. I've driven the cars for hundreds of miles and this still happens. This only happens when going backwards. Anything to try???

2013 Prius 3 making a squealing or rattling noise when accelerating after car is warmed up. It only does it when the car is up to temperature and when you accelerate slightly harder, like going up a hill or something. It sounds like a pulley or something squealing. It has been to the dealer and of course they couldn't duplicate the noise or see anything wrong. Not to sound funny, but it actually sounds like a hamster running on a wheel. It is very annoying. It is not a constant noise, it only happens under load. It gets louder when the ac is on as well. If you let off the accelerator when it starts the noise goes away. I don't know of it matters but our car has the forged 17" wheels on it from the factory, and the car has 8600 miles on it.

I recently purchased a new (to me) 2010 prius and I've been noticing that sometimes, but not always, I hear a fairly loud noise when lifting my foot off the brake pedal. It sounds like a squeak or squeal, and I want to say I can almost feel a tiny bit of resistance in the pedal when it happens though that could be in my head. The noise does NOT occur when pushing down on the pedal (only when lifting), and it seems to only occur when the car is stopped.

I remember that my 2005 Prius had a short whirring noise when I shut it off, as some coolant fluid was moved around.
But my 2010 Prius has been pretty quiet at shut-down, until recently (has it always been there, or now that it's cold weather?) I noticed there's a very faint whirring noise coming from the engine compartment at shut-down. It lasts for quite a while -- almost a minute, then stops.

Is it my wheel bearing, rotors or brake pads?
How do I describe it... well it has this squealing noise and it's proportional to my speed.
Heard this while I had my windows rolled down.

Recently my car has been making a noise from the front and rear wheels (sounds like metal scraping against something). It is more pronounced on the driver side and there is a definitive roar at highway speeds. I have had the tires rotated, balanced and tire pressure checked numerous times and still no fix. It has 37K miles on it.

2009 Subraru Impreza Outback Sport (60K miles).. I'm trying to figure out what's wrong with my clutch. When I start my car I hear a squealing noise from the engine that sticks around until my car is warmed up. If I depress the clutch while it's warming up (and squealing), it goes away. Bearing?

I had a 12" sub installed in my trunk & was getting a horrendous rattle from the rear deck area. My first instinct was to put Dynamat everywhere but after some googling i ended up filling the underside of the rear deck area with trashbags!! I pushed 5 of them through the opening where you access the 3rd brake light & it now it sounds perfect. I uploaded a video to youtube with a sound test.....

I turned on my AC in my 94 ford f250 and it made a squealing noise then I started to smell smoke or more like electrical burning. I turned off the AC and the squealing and burning stopped. I found that the compressor was the problem and after pulling the pulley and clutch assembly off I found that the coil had melted or got really really hot and smelled lie it had burned. My pulley and surpentine belt were still spinning fine so what happened? My AC had worked fine a few weeks before this.

I've bought a brand new 2012 Prius C 3.
This morning I was trying to back out of a parking spot and put it on a reverse after starting my car. As soon as I my car started moving forward and hit the curb right in front of the car. I couldn't believe my eyes so I put the gear back to Parking and back to reverse, and as soon as I touched gas, it again accelerated forward.

My R has 56k on it. it sat for just over a year and a half and i just got it back on the road a week ago. Two days ago i started it to pull it on my rack and change the oil and it was making a rattling/chattering noise. The noise was going away when i pushed the clutch in but not anymore and the noise goes away in the higher rpm's. on the way home it threw a code and the check engine light came on and with throttle it started making an awful squealing noise. I am kinda scared to drive it.... I guess ill start pulling the motor, transmission or both tomorrow...

Twice in the last month, my 2010 Prius has made this incredibly loud noise when the engine first started up. The noise continues for a minute or two, and then stops. The car then runs as normal. I brought the car to my dealer, who after a brief looking-over could find no reason for it. I shot a video of the car making the sound the 2nd time it happened and brought it to the dealership with me to play for the mechanic. No one who heard it there ever heard anything like it before.
It has been really cold here this winter, so "cold oil" was once thought, but was dismissed as unlikely. The car gets 0-20 oil.

So a few months ago I would occasionally hear what appeared to be a slight squealing noise from a pulley when I started my truck. It was very intermittent, so I didn't think much of it.
After a few weeks, I realized I was only hearing it on colder mornings - it would also go away rather quickly. I bought a mechanic's stethoscope, and figured I'd get to it on a slow day.
Today, I finally broke out the scope and tried to figure out the source. Didn't really find any pulleys making noise, and I did notice that when I shut the truck off, it squeaks for a second or two as it comes to a complete stop.
My dream of finding a bad pulley or perhaps a power steering pump was crushed. I had hoped to do a little Easter wrenching and put this noise to rest. So, I did what any good mechanic would do - I Googled the issue.
I'm reading that it could be the belt. Certainly wouldn't bother me too much as that is an easy fix. The belt isn't too old - about 4 years and 20 - 30K on it.
I took a few pics of the belt and can take a video of start/stop ....

Well, I last summer my fuel filter/ pump started squealing, and making vibrating noise, replaced the fuel filter changed the noise slightly, some times it would go away, sometimes the line going to the filter under the hood would vibrate, couple weeks ago truck warning light came on- "low fuel pressure warning" came on, hum... went out, came on a couple days later, then finally put me into limp mode, luckly only 1/2 mile from home... checked filter on frame/ tightness, it was tight, the pump on the filter housing was very noisey still, well, I figured 200 dollars cheaper than taking to ford....
I waited and pump arrived 3 days later, replaced it and low pressure warning still on, but pump was very quiet, and when I restarted low pressure warning and reduced power came on in driveway, hum.... I thought code was still in computer, I disconnected battery and turned headlights on to try and kill the code, started it and now the engine light came on, nothing else, and truck ran fine....hum.... went to autozone, and they pulled the code, low fuel rail pressure, p0087, guy said to drive and code should go off, truck runs fine. Drove truck a couple days and engine light went off, Truck runs great.......All is good.

I have been noticing a slight noise when turning left and I cannot recall if this is normal or not. Typically I always play music when driving. It's very faint and sounds like scraping. Seems to come and go depending on the temp....that is when warmer I do not hear it. I got less than 1000 miles left on the warranty and would like to get opinions if it necessary to take into the shop. Btw, the shop wants $125 to walk in the door...hence the hesitation.
Prius 2006 99200 miles. Never had an issue.

Our 2010 Prius has about 57K miles on it (mostly highway and rural commuting). The rear brakes just started to make some noise the other day at low speeds. It sounds like a light metallic squeal, similar to a brake pad wear indicator. It only occurs at low speeds and in reverse. Last time I checked the pads, they had lots of life, but that was in the spring.
I'd like to take apart the brakes to service them, but I don't know if this is a DIYer job on a Pruis. I have tons of experience on auto repairs, and have done hundreds of brake jobs (I also perform auto restoration as a hobby and have done almost every type of mechanical work on a car). So I am not really worried about my skill, but I am worried about knowing the proper procedure to do the repairs on a Pruis.
