Prius C :: Clicking Metallic Noise Up To 1 Second After Releasing The Brake
Oct 11, 2012
I should probably arm myself with a sound clip, you can hear it with radio off windows up, but more prevalent outside or windows down. whenever I stop and release the brake, there is a metallic clank noise that is heard outside the car. now I didn't want to bring it up to the dealer, but at my last service interval, I test drove a brand new Prius C and I could not duplicate it. So I don't know if its something that developed after it brakes in and is normal.. The prius C I test drove was utterly quite going from brake to gas until the point the whirling sound starts. mine has a metallic clank and it usually is not immediately as I release but within a second, and I thought maybe it was a change in the regen system, but now I am more curious as a brand new one did not make that sound.

I get a clunk noise when stepping on and releasing the brakes occasionally but not always. This occurs even with the engine off and the vehicle stationary. I also hear some other noise like some sort of vacuum servo thing is happening.

I had 2 brake related issues. First was a honking noise when pressing/releasing the brake pedal (covered by T-SB-0363-10, attached below). Second was rear brake squeaks, particularly when backing up (T-SB-0102-11, attached below). I had the squeak issue repaired under a previous TSB a few years ago, but the noise came back after a while, and the updated TSB includes replacing the pads and other parts.

I think I have a bad prop shaft CV joint. The car has been intermittently making a metallic clicking noise from the middle of the car. It can happen at any speed, a slow crawl to the highway. The frequency is completely tied to speed over the ground and seems to be once per revolution of the prop shaft. I put the car up on a lift yesterday and slid back the heat shield under the CV joint and bearing in the middle of the prop shaft. There is grease there that looks like it was thrown off of the shaft. Can the CV joint be replaced by itself or am I looking at replacing the entire prop shaft assembly?

Metallic Clicking During Light Acceleration on Prius C....

2012 Prius 3 with solar roof. Most of the time when I go over little divest in the road; just large enough to barely feel, I hear a metallic clicking sound from the front passenger side of the vehicle. It is only audible with the windows down. It only happens if I am going faster than around 10mph. Sometimes I hear a similar sound from the drivers side, but not as much as the passenger side. I do not usually hear it when hitting larger bumps that work the shocks a bit harder.
It really sounds like some loose bits of metal contacting each other. I do not see anything obvious with a quick visual inspection, but I have not raised the vehicle to really get a good look down there.

I have a 2005 Silverado Crew Cab 1500 with a 5.3V8, discs in front, drums in rear.
Series of events:
2011- Grinding noise from passenger front tire. Sounded like metal on metal. Removed tire to find that inside brake pad was completely worn down. I thought, at the time, that the pad separated from the plate, and fell off. I noticed at the time that my caliper was stiff (not releasing). No other (apparent) problems at the time. Drivers side pads looked as expected when I replaced them.
December 2012- Grinding noise from Drivers side front tire. I pulled the tire and found that the inside pad was completely worn. All the other pads looked fine. Still noticed that both tires were difficult to spin while in the air.
Feb 2013- Fuel economy has dropped an average of 3 mpg, since December. Started hearing an intermittent squealing/grinding noise from the front end. Seems to only happen when turning left (that could also be from my proximity to the front tire). I had my dad stand outside the truck while driving in circles. He said he couldn't be sure it was coming from the drivers tire. Sometimes the noise is loud. Sometimes its faint. The majority of the time there is no noise. The check engine light came on and I had a C0035 and a C0055. They are a Drivers side front speed sensor and a Vehicle Speed Sensor. Decided to change the drivers side caliper. I used pliers (yes I know I shouldn't have done that) to pinch the brake line to minimize fluid loss. Bled the line.
March 2013- Brakes have partially locked up on me twice in the last three days. I thought there was an electrical fire in my truck based on the smell of the brakes. I couldn't press the pedal. It was like pushing on a boulder. They didnt completely lock, but I could tell they were stuck. The second time it happened I drove immediately home and jacked up the front end. I could barely get the drivers tire to move. I cracked the lines from the master cylinder and some fluid came out. At that point, after reattaching the line, I could spin the tire easier than I have ever been able too in recent history.
Now, Ive read that the speed sensors on my truck are problematic. I'm inclined to think, since cracking the lines on master cylinder released the caliper, that the master cylinder is the problem. I just have difficulty rationalizing that the master cylinder would cause this problem, as of recently, predominately in the drivers side. It could be happening in the passenger tire as well, but it is not apparent.
I also use the parking brake every time I park my truck, even though its an Auto. I don't know why, but its habit.

Over the course of the past week or so, I've been getting an odd noise from the rear driver side of the vehicle. It's kind of a metallic clicking sound, but the clicks are rather erratic. As I accelerate, the duration between clicks decreases. It's not a "click.. click... click..." noise either. More like, "click click... click... click click click... click click..." If that makes any sense at all. I'm thinking that my wheel bearing is going out, but I don't know for certain. What I might be looking at?

This noise started this week. Grinding when I take my foot off the brake when in park and parking brake set. What is causing it?
A guy at work said brakes. The front brake pads were replaced last year. Original rear.
Just over 90,000 miles.

Today I stopped at the post office to check my mail. I put the car in park and didn't shut off the engine - this is what I always do. When I returned a few moments later the car would not go into reverse (this was after releasing the parking brake) and the traction control symbol came on. The car would go into drive but that didn't work much as I was up against a hill (or almost against it). Shutting the car off and turning it on again solved the problem. The parking space was badly potholed; I'm assuming I had less than full contact on one wheel which caused the traction control to kick in which prevented reverse from engaging. And to be clear - it's not that it went into reverse but didn't go anywhere; reverse simply wouldn't engage (I did not try neutral),

In the last couple of months I have noticed my '10 Prius III begins to roll forward or backwards about a foot depending upon which drive mode I select without releasing the brake. So here's the normal scenario I get in the car have my foot on the brake, turn it on wait for the ready beep/light, my foot has never left the brake or lessened pressure but not so much as to trigger the hill assist, I shift into D to go forward but say a car is coming and I don't want to go yet my car moves about a foot forward and I feel the brake pump up and then resist my foot. The same thing happens if I put it in R she rolls back a foot and stops. I don't recall noticing it before the great ECU update but I also can't say it didn't happen before the update was accomplished.

2013 accent auto My car rolls noticeably after parking unless the ground is completely flat. Parking brakes prevents it from rolling but I don't use parking brakes every time. Another brake problem I have is thump or clunk noise I get whenever I release a brake from stop.

The truck in my sig. makes a clicking noise when it's in the park and I press the brake pedal down. The click is coming from somewhere up high in the steering column. It doesn't make the clicking noise in any other gear only in park. Might be normal but I don't remember hearing it before?

I have a 2008 Prius with the platinum 7 yr/100K warranty. The brakes are making a creaking/clicking noise when pressed. It only happens when the car is coming to a stop. If you start the car and sit there and press the brake pedal it doesn’t make the noise. Only when the car is in motion and coming to a stop. I took it to the dealer and they said the brake lever/shaft needs to be lubricated. It is only heard on the inside of the vehicle and doesn’t seem to affect the brake performance.
They said it would not be covered under warranty since it was a lubricating job and not a mechanical problem. They said they would have to take apart the whole dash to get to that part to lubricate it. It would be covered only if the part has failed or broken. They called Toyota to approve the fix, but it was denied. It is just annoying to hear the creaking noise every time I come to a stop. I am supposed to pick up the car tomorrow since they are replacing some other items. I asked for a parts diagram of what part needs to be lubricated to see if I can get to it. I have to take part of the dash apart to install my LockPick and XM radio.

I've had my 2012 PriusC for about a year now and I'm loving it. As of a week ago the car has started doing this revving thing. I notice that the engine seems louder when I'm accelerating and it seems like I'm getting 30-40mpg instead of the usual 40-50 in cities (but it might just be me).
What worries me is that when I'm driving and I push on the pedal to accelerate, after I release the pedal there is a very loud whirring sound of the engine. It sounds like a MuscleCar or Racecar that is revving it's engine but not going anywhere. This sound happens if I accelerate lightly or severely and the revving sound is louder the harder I accelerate. I notice that if I accelerate and then ease off of the gas slowly, I don't hear the revving sound.
I notice that this seems to happen randomly, as in I start the car and it happens from the start, or I start the car and it doesn't happen at all for that drive.

Over the last few months I've noticed a clunking/rattling in the front end somewhere -- probably started at around 60,000 miles. I've considered T-SB-0300-08, but it can range from a clunk-noise to a metallic clunk-noise, and is often felt on smallish bumps. Sometimes I can feel a knock in the steering wheel, especially at very low speeds. I get the distinct feeling that the front wheels might be wobbling a bit as things clunk going over small bumps. Predominantly a left-side thing, but not exclusively.

This morning, I hit the brakes medium hard and got a short metal-on-metal 'scrape' noise from the rear end. It sounded like a brake shoe to me. Later my wife was out shopping and did a 'regular' stop and got the same noise.
The car isn't driven a lot. It's just under 1.5 years old and has 5,400 miles on it. So, I'm pretty sure there isn't a lot of brake wear. Maybe a little above average from mostly city driving. I assume the rear brakes are self-adjusting. Do they make noise when they are adjusting?

Our 04 Prius makes a really scary metallic noise at the top of the engine when it is engaged. All maintenance has been performed within 100 miles of the warning light. We are the original owners and the car has 160k miles. No pulleys are touching their surroundings. Make no mistake, this a LOUD noise that has been growing with time. No warning lights,,,oil level is fine,,,and no metal visible on the dipstick. Sound is originating at the top of the engine and is not a "knock". It is more of a metal on metal type of noise.

While driving through a tunnel today I noticed a metallic rattling noise upon acceleration. It goes away immediately when I let me foot off the gas and when I park the car and rev the engine the sound does not occur.
A few days ago, I had to rapidly accelerate and it felt as though I lost power for a split second. I am not sure if these are related, but I am hoping its not some sort of transmission issue (unless that is covered under the hybrid warranty. What was the diagnosis?

Lately I've started having an intermittent metallic noise that has been bugging me. At first it occurred on long runs and sounded like it could have been the brakes or something similar. It is not too loud but is continuous, rather like gently rattling your set of keys.
It got steadily worse and I eventually tracked it down to the passenger seat. When I held the seat the metallic rattle stopped.

First the specs: 2008 w/38K, not sure which package but nothing fancy. This morning got in the car and started off and hear a metallic rubbing noise coming from the left rear of the car. Sounded like it came from around the wheel area. Temp was coolish around 36 degrees. The noise only happened for the first few minutes and only when going real slow, like 5 or 10 mph, and only when I was turning right.
Sound was like the the sound you get when a brake pad is worn way down and scrubbing on a rotor or drum. Also, the sound would speed up as I sped up until a certain speed then would go away. I actually stopped and restarted to be sure I could make it happen again. Once the car warmed up I couldn't reproduce the noise. Drove the car later in the afternoon with temps in the high 40s and no noise. Also, I never use the E brake so can't imagine that would have any impact
