Prius C :: Metallic Noise When Hit The Brakes Medium Hard
Nov 8, 2013
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?

There is a pretty loud continuous clicking noise lasting about 30 seconds (not necessarily a bad one - just annoying) that comes on every thirty seconds to a minute when I'm driving my Prius. It happens more often now than it did 10,000 miles ago.
It also happens without fail for a few seconds every time I brake. Is this a normal noise? I fear it may be associated with the brake actuator--which the chirping noise is associated with.
If I press firmly on the brakes (which is rare), they chirp. Toyota released a bulletin on it. TSB BR001-07

Well this week, everytime I was backing up, hit a pothole or sometimes when I turn either left or right or hit the brakes a clunky or sometimes metallic sound appears coming from the back the undercarriage.
First I thought may be one of the bars (TRD or the Ultraracing sway bars) were loose, we lift, checked the car with the guy who installed the bars and all of them were tight ,nothing loose, we discovered on the front is time to change the bushings of the front stabilizer bar and also the rods who run parallel to the shocks absorbers but we couldn't mimic the sound the shocks are fine.
Tonight my daughter was driving the vehicle so I have a chance to hear the clunky noise, which I think is coming directly from the inside of the drums the sounds intensified at the time of hitting the brakes but is not all the time you hit the brake when it happened.
Also I can't explained why I heard the sound when I turn left or right and still coming from the back, doesn't make sense I can't find no relation whatsoever
I just add this 2 videos..

I have been getting some knocking the under most any loads . I do not have any codes. I tried premium gas and that did not make any difference. If this is not fixed what issues can this cause? What should I look for do get this fixed?

I recently had rotors and brake pads replaced on my 2007 Camry (front pads/rotors and read pads/rotors).
It was done last week and she is braking fine. But sometimes now when I brake there's a low-medium squeaking sound from the brakes. Is this normal / what's the likely cause?

I have a 2007 LS460L. Bought it new and have loved it dearly for 6 years now. It now has 70k miles and is under an extended warranty purchased at 50k miles. As a first year model it has had a ton of TSBs done on it.
The problem i have had as long as i can remember is a lag or stutter during medium to hard acceleration. It feels a little like the old turbo lag or like a very mild stutter. It has had the transmission adjusted, had the service manager driver it for a week to try and capture on computer etc. But nothing has fixed it. At times it feels like if you watch the tachometer during these moments you can actually see a bounce (I may be imagining).
I have almost given up and just lived with it. We have tried tranny, type of oil, software tweaks etc.

I have a 2009 V6 Ltd with about 15k miles. It has always seemed to shift a little too hard from 1st to 2nd and from 2nd to 3rd under light to medium throttle. Does this sound like a transmission ill that can be fixed by adjustments?

Everytime i accelerate medium to hard with the CEL on like this it starts flashing and i loose power. Feels like a sputtering (in idle too). Fuel injection system cleaned and was 75% better for 1 week, but now back to same old. Reset CEL and comes back 100-200 miles later. Cam tensioner? Fuel filter? Coil packs? One of my fan clutches is pretty much out, related?
New spark plugs, maybe needs a tune up...supposedly TB was changed, but i have 106K on 1.8T 2001.5 Passat. New oil pump, timing belt tensioner put on. However A/C belt snapped and had to be put back on then tightened to work. Maybe they didn't adjust correctly at shop the timing belt tensioner?

I have a 2012 Explorer Limited with 95K miles. Under medium to hard braking, the steering wheel wobbles, and the car slows irregularly. I'm struggling to find the best word to describe. It's not a vibration or a shudder. It's like a pulsing that is slow enough to be counted. The car doesn't pull to a side under braking, either.
I put a dial indicator on both rotors, and they are nearly perfectly flat. There is no evidence of a leak anywhere. The only think I noticed is that the DS caliper had a little more pressure on the rotor, making the rotor harder to turn than the PS rotor.

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.

Starts good cold and hot. Taking off like a grandpa on an evening drive don't notice a thing. Only codes that keep coming up are 2614 and 2617 which are cmp and ckp open curcuit codes and a software incompatibility code for FICM which is due to the updated software in the fresh FICM I installed. HPO pressures are good, has boost, idles smooth, revs nice when in park. New injectors (cause it was running rough especially cold before) and CMP and CKP (because of the above codes and didn't change)and ICP and IPR (last 2 installed because of HPO codes that are gone now with the IPR and ICP). Fuel pressure is 65psi (updated spring). When you step on it while driving it sputters and bucks like it's out of fuel, let off the throttle a bit and it purrs like a kitten. I'm a little stumped. I think it puffs a little white/blue smoke while it bucks.. not much tho. and it comes in little puffs. Took off filler cap and there is almost no blow by.

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.

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

Noticed a weird metallic rattling noise coming from the transmission when switched to N with the engine running and the car is stationary? Almost like the gears are rattling inside while in N position. I took it to the dealer and their Prius guru said this is normal characteristic of eCVT....

So I noticed this when I had my windows down and the music off (or very low) for the past few weeks (at this point). About 3800 miles on the car, and maybe once or twice during a drive It is an occasional clank/ metallic noise that sounds like it is coming from either the left or right side depending on which tire hits the bump. But I can go over any number of bumps before and after with no noise at all, and it's not like I'm hearing it on just large bumps/ potholes. I've never heard it on any speed bumps.
I have a feeling it is when only one tire drops down a bit from a small bump, but that is only a feeling, and it's on small bumps. I tried looking up other threads on here for suspension noise, but mostly only finding things dating back to 2011 or so with brake caliper pins, possibly motor mount but nothing really recent.

Two weeks ago I took my 2004 Prius (with about 165,000 miles on it) to the dealership because of problems with the rear (drum) brakes grabbing (sometimes hard enough to lockup one of the wheels). Their diagnosis was that they were badly out of adjustment. They "cleaned, adjusted and beveled rear brakes" which fixed the problem, but it returned this morning. I should also mention this dealership had "cleaned and adjusted" the rear brakes twice before over the last couple of years.

This morning when trying to leave for work, my prius refused to turn on. When you press the brake so you can press the start button, the brake feels extremely hard, almost like it doesn't want you to press it. The light on the start button becomes orange after a pressing the button once. And on the dashboard screen (I don't know what call it on a Prius) in the very bottom right corner, a red notifications light flashes very quickly, so quickly that is hard to tell what it is, but by staring at it for like 30 seconds it looks like the symbol of a car with a lock attached to it. I may be wrong though. My Prius v is a 2012 model, trim three, and it has a little over 60,000 miles on it. I also have a prepaid maintenance through the dealership. I don't even know where to start.
