Prius (2004-09) :: Squeak From Engine Compartment When Pushing Brake Pedal
May 27, 2010
A few days ago, while on a road trip from CA to CO, I noticed a loud squeak from the engine compartment every time I pushed the brake pedal, no matter how lightly, no matter what speed. It even happened when the car was off. I have almost 60K miles on my '05.
When I arrived in Denver, I dropped the car off at a Toyota dealer for troubleshooting. They isolated the fault to a bad ABS actuator. They had to overnight the part, and spent a day and a half installing it. Sounds like a major project!

So, just recently I noticed my car squeaks when I push on the gas pedal. I've researched up and down and can only seem to find that it is "Normal". It only happens at very low speeds (Stop and Go). I've read it could be anything from exhaust leak, DSG/ Tranny, belts or cv joints but nothing i've read seems to be exactly what I'm experiencing.

I have recently purchased a 2007 Gen 2 Prius and sometimes it emits a very annoying squeak. It occurs when the car is stationary, with the brake pedal fully depressed. When inside the vehicle it seems to be coming from behind the glove box. When on the outside and facing the car it seems to be coming from below / behind the electric motor. I have made a recording of it with the noise in question being audible for a couple of seconds at 0:13, and then again at 0:22 until the end. It could be nothing I guess, but this is my first hybrid and I am not too sure what is perfectly normal and what is not.

My new GX460 has 120 miles now, and starting today, I heard noise when pushing the brake pedal. After get the parking lot, I turned off engine, and used hand to push the brake pedal, I can hear same noise, which like a air or gas squeeze out. Seems not big deal to me, just like to see do you GX460 owner have similar thing or I need to to dealer again.

Well my brake pedal is stuttering while pushing down. Have an abs light. Pulled codes. Left front sensor issue. Would this cause my pedal stutter? Removed #10 fuse in cabin and it stopped. So did the speedo. So thinking before I dive into a master cylinder or brake booster....replace sensor? So do I get the 4wd sensor or the 2wd?

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.

So towed the trailer down to a remote lake side spot over the weekend, pretty bad dirt road with lots of breaking bumps. Now pushing the break pedal creates a swooshing noise, and a vibration under the hood around the master cylinder, and the power steering whines a little bit. Took it two several mechanics and 2 think it's the pump, one thinks it's the hydro booster? I tried to bleed any air out by turning the wheel all the way maxed and pushed the brakes, did nut really work, but I did notice that when pressing the brake pedal and turning the steering wheel at the same time, it becomes extremely difficult too turn the wheel, makes me think it's the pump because there is not enough pressure to do both?

I have an 08 Sonata Limited. About a 3 months ago, a noise began appearing on the driver side, sounding like it was coming from the engine compartment, and it has become steadily worse.
Today, I am learned how to replicate the sound, but I cannot locate where it is coming from. Here is the scenario:
The sound is a squeaking, like 2 pieces of styrofoam being rubbed together. The sound comes and goes. The engine must be in Drive or Reverse, and under load, meaning the driver side tire must be on the ground. If I jack the car up so that the drivers side wheel is off the ground, and put it in D and let the tire turn freely the noise does not occur. The car does not need to be moving for the sound to occur; in fact, it sounds worse when the car is at rest.
Today, I jacked the car up and took off the drivers side front tire to see if I could identify the source of the noise. Later, I put the tire back on the hub, and without lowering the car, started to tighten the lug nuts. When, I tightened the nuts with a wrench, I began to slightly turn the axle and shift the location of the engine and lift it, and I heard the squeak! Obviously, the car was turned off, so I was able to repeatedly shake the wrench and slightly turn the wheel, which shook the engine, and repeat the squeak each time. I lowered the car and jacked up the passenger front side of the car and did the same thing; I was unable to get the sound to occur.
I could now identify the direction of the sound, and it was coming from under the air filter chamber. I tried removing the air filter box, but it is held in place by a rubber plug and the air intake tube. Unable to remove the box, I could not see exactly where the noise was coming from.
Is there a motor mount under the air intake box, or is there another part that may shift over time and begin to make this noise? My best guess is that when the car is in Drive and under load, the engine vibrations are causing something to make a squeaking sound.

I have a 2007 Toyota Prius. When I press the brake pedal and press the start button the engine does not start or the wheels are not powered by the battery. It gives me the following errors:
The indicator in the Start button lights in Amber Color.
0 kmph mark is not activated in the dash board pannel.
When I shift the gears it only shifts to neutral ("N") gear.
I cant move the car forward or backward. An error message is displayed in the MFD in Japanese language. It is in Japanese and I cant read the error message.

While pushing the gas pedal for acceleration from stop I feel the engine grunts more and then on its smooth. I don't have any lag in acceleration the car moves well. The car is 2008 Sonata 4 Cyl. the mileage is 137000. Is this normal for this mileage or something wrong. When I asked the service center guys, they replied they don't find any issues and everything is fine. It might be due to the mileage on the engine.

Just got a 2012 Lexus RX 350, but find out that the engine sound is quite "noisy" in the lower gear or when pushing the pedal. Is this just my car, or is common?

Started a few months ago didn't really bother me until now. Started when I would forget the parking brake is on and would just put the car in reverse & wouldn't move until I released the parking brake. Did it about 5-7 times and now every time I brake without the parking brake on, it squeaks & is really annoying. Is there any way to fix this or is it just gonna be complicated & expensive?

Purchased this car used with 64k miles on it. I am in the process of performing the 60k miles service items and going through typical replacement of worn parts.
I have noticed that my rear passenger brake drum assembly squeaks when I let off the brake pedal. Note that this is not noise when applying brake pressue, but after releasing the brakes. Additionally, the drum happens to be rusted very badly. It took a good amount of brute force to remove the drum in order to inspect the brake assembly. There was a lot of brake dust built up and I thought that cleaning that out would get rid of the noise.
I suspect it could be one of the springs but I cannot be for certain. The squeak does not occur when I release the parking brake.

I have a 2015 IS250 F Sport with brakes that squeak. First time dealer said can't replicate and suggested hard braking to burn off any residue on rotors. Second time, dealer replace rear brake calipers which resulted in mix match colors of the brake caliper and bracket. Not happy.
Well it's starting to squeak again. Not sure if moisture and or cold has anything to do with it. Washed the car yesterday and as I was moving it down the driveway (small incline) the brakes squeaked as soon as I released the brake pedal. I was able to replicate this several times yesterday.
This morning brakes squeaked as soon as I released the brake pedal. Not on an incline driveway today.

The squeak is most pronounced when the brake pedal is released, but it still makes a quieter squeak when the pedal is depressed. I can't tell which side it is coming from; my guess is the middle of the rear or the left rear. I can't tell because I have to be in the car to release the brake (I guess I could tie a string around a brick and pull on it when I'm by the rear wheels). I should mention that all three of the belts are due for a change. Which part is causing the brake system squeak? The brakes work; replacing the squeaking part or parts is going to be lower on the project queue than the CD player/radio errors and replacing the belts, pulleys, etc. in the engine compartment (I've posted elsewhere on the forums about those issues).

First off it's a 2008 Prius with 80K on it.
There is a new sound that has started coming from the front of the car in the engine compartment or even lower. It is a turning turbine like sound that is mostly obvious when driving at 60 mph, but my guess is that it is always there, but not as audible at lower speeds. The air and heater are both off and have no effect on this sound. The only thing that could have had anything to do with it is that a day or two before, the tires were low so I filled them to 40 psi. The other thing is that it clicked over to 80K the last week and the friendly red maintenance required light came on.

Developed a whining type noise in my '07 prius engine compartment. Noise only there when gas pedal pressed. If I let off on gas the whining noise stops.

I have a 2004 Prius that has a ticking noise coming from the engine compartment It speeds up and slows down with the idle of the engine or the pressing of the accelerator. Appears to be coming from the passenger side (US). No diagnostic codes have come up.

I had whining from the engine compartment when I am coasting and accelerating, much noiser than in the past. I had been getting a C1310 code along with C1253 , C1241 and C1300, but I changed out the Anti Skid ECU and these went away. However I still get the red triangle of death VSC and ABS lights on after driving on the highway for about 10 minutes at speeds over 65. So I then got P0A2B 250 codes, Drive motor A temperature sensor. After it rested a while and I restarted the car, all but the red triangle would go out. After two more starts the Red triangle went away too. This happened for a few weeks, until one day after a trip, the car just stopped. Would not start at all, no ready light went on. Testing gave me a P0AA6 526 code, Hybrid Battery Voltage System Isolation Fault. Now I know the 526 could be multiple faults but with the whining and the P0A2B, I am thinking the transaxle is the smoking gun.

I first noticed a strange noise coming from the engine compartment a day ago. I had left the car to sit in the sun for a few hours. When I got in the A/C was set to on and the system was on auto. I tested to see if the noise went away when I turned off the A/C and it did. I turned it back on and it returned. I know the A/C operates at different speeds based upon cooling needs and that it can get sort of noisy but I didn't think that it could/should get this loud. The system seems to begin working quickly and it does seem to put out cold air. If the noise is unusual do you think that it indicates another underlying problem in the A/C system?
Just to clarify, the ICE is not running in the video. The cabin fan is set to low and the temperature is set to low. The person in the car presses the A/C button and the cooling fans in the engine compartment come on as well as the A/C unit. The sound gets louder a few seconds in. Here is the link to the recording I made of the sound.
