Prius (2010-12) :: Brakes Don't Stop Well In Some Areas Having Metal Object


Nov 5, 2011

This has happened a few times in the last 3 months. Maybe I'm just beginning to notice or something is wrong with my Prius.

I put the brakes on and all of a sudden it's like I can't stop. Yesterday I thought I was going to hit someone. I have noticed that it is usually if there's a metal object on the street-- a railroad track or manhole cover.

Camry :: 2010 - Passenger Side Rear Brakes Making Metal On Metal Sound

At 75K my passenger side rear brakes were making metal on metal sound. I was really surprised as I have always learned that the front brakes take 80% of load and they always go out before the backs. So I took the wheel off and sure enough the pads were metal on metal. Changed everything out. (new rotors). I then went over to the driver side rear brake. Looks brand new. The pistons were barely out. I figured this caliper is bad. (I haven't change yet)

When I drive I can hear a very faint metal on metal sound when I brake. VERY FAINT. So with 75K miles on I figure the front brakes are due. Today I took the wheels off and inspected them. Tons of pad left on both of them. If I didn't know better I would say a brake job had been done very recently. (I've owned the car new so I know they have not had a brake job) However after reading many articles on this site I found a thread where one user said he was changing his front brakes for the first time with 110K on them and the pads still had 10K left in them. So the fact that my front pads are still pristine at 75K may not be a big deal (or not as big as I thought. Also I am not hard on brakes.)

However I'm not sure what is going on. Why would the passenger rear brake be metal on metal at 75K and the three other pads are like new. Is the passenger rear the only one working (or working much harder than the others) meaning the other three are bad? Or is the rear passenger bad and the other three are good? I have a working knowledge of cars but I am by no means a mechanic.

Prius (2010-12) :: Metal Ball Rolling Sound When Coming To A Stop

I have noticed an odd sound when coming to a stop. It sounds like a metal ball or two rolling forward when I brake then roll back and hit something when i come to a complete stop. At first i thought it was just something rolling around in the center console but I haven't found anything. What is under the center console/drivers seat that may have something that could roll like that?

Prius (2010-12) :: Metal On Metal Grinding Noise At High Speed Above 75mph?

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?

Prius (2010-12) :: Light Metal On Metal Grinding Noise

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.

Prius (2010-12) :: Metal-on-Metal Whining Sound While Running

I own a 2010 Toyota Prius that recently developed a metal-on-metal whining scraping sound when moving. It does not make sound when the vehicle is stationary, and it's intermittent - which makes me discount the rock-in-disc-rotor idea (not eliminate it, mind you). It's quite loud when it occurs, able to hear it over the stereo. Luckily I was near work at the time, so I went there - but the shop can't even look at it until Monday evening - so I am a bit panicked.

Golf VI R :: Scraping, Metal On Metal Sound That Diminished A Fair Amount When Brakes Were Warm

I picked my R up three weeks ago tomorrow. I took it in this morning because there has been brake noise from day one. The noise was a scraping, metal on metal sound that diminished a fair amount when the brakes were warm. I only got a very brief conversation with the service agent at the dealership this afternoon, and all he told me is that they had to order in new brakes. I don't know if it's just pads, or calipers or rotors or the whole deal! I'll get the whole scoop tomorrow.

Sonata I45 (YF - 2011+) :: Metal On Metal Sound When Approach Stop Sign

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.

Ford Excursion :: Brakes Sounding Like Metal On Metal

The brakes were sounding like metal on metal. Three wheels in, some of the pads needed replaced but none were worn out. I got to the right rear wheel and the inside pad is worn to the bracket but the outside pad hardly looks worn at all.

I'm already replacing rotors, pads and calipers (I wasn't going to replace the rear rotors or calipers until I got to this wheel). Is there anything else I need to check because of such uneven pad wear?

Toyota - Prius :: 2010 - Failed To Stop When Brakes Applied On A Steep Downhill In Slight Rain?

Why my 2010 Prius has 3 times now failed to stop when brakes were applied on a steep downhill in slight rain? Happened a year apart with no slick road and with tires both new and old. I pull up to a stop sign on a grade, apply brakes, the car slows, then there are metallic noises and the car glides 3-4 feet before stopping. I'm lucky no car or person was in front of me. Honestly not a skid at all. Service tells me I don't know about anti-lock brakes but I've driven with them on cars for many years with nothing like this.

Prius (Gen 2) :: Metal Hardware Pieces For Brakes Have Broken

The little metal hardware pieces for my brakes since I've had the car they have broken three times within a year recently. A mechanic who was the last to replace them said the brake pads were fine and wasn't sure why they keep breaking. Going to add a picture of the piece I'm talking about.

When driving my Prius when below 40 mph the two front tire area makes an awful clanking sound because of the hardware breaking.

Lexus GX 2010+ :: 2015 GX460 Park Assist Only Alerts When There Is Moving Object Near

Does the 2015 GX 460 beeps when you're really near an object? Mine only alerts me when there is a moving object. I checked the lexus park assist and it's on but no alert. It doesn't alert when I'm reversing or when I'm driving forward when I'm parallel parking.

Prius (2004-09) :: Metal Rattling Noise From Brakes Right Front When Going Over Bumps

I'm pretty sure I know what the problem is since when I hit the brakes it stops. When I took the left side tire off and right side I compared and there is a thin metal sheet that has room to move on the right, but is tight on the left. When the brakes were done before maybe it didn't seat correctly or something. Just wondering what that plate is called so I can order one and change it. Driven that way 2 years, but it bugs me when the window is down and people probably think my car is falling apart. Maybe I'll search for a brake diagram.

Edit: I think they might be called "anti squeal shims". I saw a picture of them, so maybe they didn't put enough high temp grease, but the left side is tight and the rights side you can move a couple milometers side to side so I'm sure that's the jingling noise.

Lexus RX 2010-15 :: Navigation Can't Find Some Places / Shopping Areas

My Lexus 2013 navigation system seems to be less than reliable when it comes to finding shopping places and even other places. I was directed to a wrong place or residential area quite a few times with my nav system.

I rate the nav system as POOR in my Lexus, I am extremely disappointed and have to use a Garmin GPS to supplement the installed system.

One curious thing.... The software in dated 2011 and the car is dated 2013.

Elantra MD (2010-15) :: HVAC Blower Noise / Metal On Metal Rubbing

My Elantra's HVAC fan has always been a quiet thing, even on 3.....we won't mention level 4 and the fact it sounds like a 747 at takeoff.

I kid you not, the very evening I hit 60,000 miles and the general warranty expired, the blower motor started making noise like it was throwing a bearing and definitely sounded like some light metal-on-metal rubbing. After I became irritated at this, the noise went away and didn't come back until just a few weeks ago. I could make it stop by smacking on the bottom of the fan assembly a few times but I want a more permanent solution.

Tonight I dropped the blower out which was stupid easy except for the fact you're upside down in the dark with your head in a hole. But three screws and an electrical connector later, I dropped the assembly to find no serviceable components. I mentioned this to friend of mine who's into Volvos suggested spraying some lithium grease on the hub of the blower and letting it run long enough to quiet it down. I'll do this over the next few days and report back but part of me thinks a new blower may be in my future.

Elantra MD (2010-15) :: Metal On Metal Noise When First Accelerating

I have a 2012 Elantra with 21000 miles on it. It runs well but in the last month or so it has started to make a strange noise when first accelerating. I would describe the noise as touching a fork to a metal fan...kind a "zzziiiinnnkkkk" sound, I guess. It only happens when the car has been sitting for a while and only on the first acceleration, usually in first, second, and third gear after which it immediately goes away and doesn't happen again until the next time we drive it. It seems like it would be related to the transmission except the sound is too tinny for it to be the gears. It sounds more like sheet metal making that sound. I took it to the dealer but they said they couldn't make it make the sound, which is crazy because it does it EVERY time we drive it.

Prius (Gen 2) :: 2006 Metal To Metal Noise While ICE Charge The Hybrid Battery

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.

Prius C :: Front Steering Wheel Thunk Like Metal On Metal

I have a question about my C Four with 16" wheels. When the steering wheel goes all the way to a stop there is a thunk that feels like metal on metal. It is like there is no rubber bump stops. If this is normal. I am used to cars that have a nice cushioned bump at the steering limits.

Elantra MD (2010-15) :: 2013 - Brakes Slip And Re-grip While Coming To A Stop Intermittently

I've relocated back to Texas, and I've noticed since the roads here are much older than the streets in Vegas, if I'm braking while going over a bump in the road my brakes seem to slip and re-grip while coming to a stop. It doesn't happen every day but it happens enough to make my heart skip a beat and think I'm about to die

I do plan on taking this to the dealership because it is pretty big problem, I have a 2013 Limited Elantra

Lexus LS 2007+ :: 2010 LS460 - Brakes Make Popping Noise When Coming To A Stop

Just purchased a 2010 ls with 20,000 miles on it. Brakes make a popping noise when coming to a stop. Not all the time, seem to get worse as brakes get hot. Have had to dealer twice they have resurfaced rotor, bled system put new pads. Still have noise my service manager opened a trouble in the lexus system and called Atlanta. They said this is characteristic of this car. I drove a couple of other ls cars and did not hear the noise. Not sure where this is going to end up. I saw where the brake actuators where changed on the 07,08 and 09.

Prius (Gen 3) :: Brakes Making Squeaking Noise When It Comes To A Stop

I have just purchase a used one 2 weeks ago. I bought it from a local dealer (Longo Toyota). After I got the car home for a day it started to make noises when i brake. If the brake pedal is depress about half way it will make a squeaking noise when it comes to a stop. So i bought the car back in to the dealer and all they did was flush the system and reboted the computer. They said this is normal for some pruis to make a noise when the vehicle comes to a stop and it should not be a safety concern.
