I brought my prius v back to the dealer for the fourth time because of the groaning noise from the rear brakes. I was told that Toyota is aware of the problem and they are designing a new rear brake. They expect it to be ready for installation after January 1st, 2013. Let's hope it isn't too far after the first of the year.
View 8 RepliesI put on etc red stuff and RB front rotors a few hundred miles ago. When I brake at highway speeds the brakes make aggroaning noise. The wheel and brake pedal do nother vibrate but the cabin does a little. What can this be?
View 4 RepliesI have noticed brake groaning sounds ocassionally when applying the brakes. When this happens the pedal seems spongy takes longer to stop. After the car is turned off in the garage I have heard the same kinds of sound coming from the car. It almost sounds like the car in sequencing through checks after the system has been turned off.
View 7 RepliesSo, my 2012 Prius has 61,000 miles and I started hearing some terrible squealing from my rear brakes. This weekend, I decided to take the tires off and investigate. Turns out, that my rear pads were worn to metal.
I switched the pads with new ones. The rotor was still new and didn't need replacing. Torqued the caliper bolt to 25ft/lb and put it back together. However at the end, I forgot to put back on the two wire clips take keep the brake pads apart!
Do I need to put these clips on? I'm too lazy to take my tires off again.
Lesson learned: Turn clockwise and PUSH the rear piston at the same time to get it to go back in. Turning it alone does nothing.
OK, so this is a 2012 ML350 Blue-tech with around 31,000 miles on it. Lately when it is warm (either by driving for 30 minutes or more, or by outside temperature of 80 plus), it has been making the strangest front end groaning noise when coming to a stop and when pulling away. It sounds like the front end suspension is "groaning". It doesn't have to be a hard stop, gentle will do just fine. The car comes to a halt, the front end dips slightly - "groooaaan" (perhaps more on the rebound than the initial dip). You start up again, the front end unloads, and "groan".
Very disconcerting on a car as smart as this. Tom and Ray know this car - this is the one with the "smart radio" (switches channels at voice command…) The dealer is stumped. They have the car for the third time now and even though both a mechanic and the shop foreman have been shown the problem (taken for a test drive ), they have been unable to come up with either a diagnosis or a fix. They replaced the front sway bar links once to no avail.
120K (64 by me & 56 by prior owner during first 6 1/2 yrs) I was having a groaning noise when going around corners especially when headed down hill and hitting the brakes at the same time. I also had a rattle or popping going over bumps. I couldn't isolate the noise and nothing felt loose in the front end when I jacked it up. The dealer said the lower control arm bushings and ball joints needed to be replaced for $1545. I asked about front struts and was told that the control arm bushing and ball joints had to be replaced first before the struts could be examined.
I replaced the control arm assemblies (had to lower front cross member while supporting engine w/large jack and removing lower engine dog bone), ball joints, stabilizer bars and stabilizer bushings myself. Ball joints required removing axles and steering knuckle assembly to remove metal CV dust shield on back side of steering knuckle. (will post procedure later). Had lined up and the noise changed (groaning on corners left and rattle became pronounced on all bumps like the front end was about to fall out). By the way no cracks or excessive wear on any of the rubber components as I have always seen on the Subaru and other cars I had.
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.
I'm trying to figure out what is wrong with my Prius. A few weeks ago, there was a big rainstorm in California, and I accidentally backed into what I think was a storm drain under very deep water. I heard a big thunk, but there was no visible damage to the car. A few days later, I noticed a low groaning noise that comes from inside the cabin, somewhere around the center console/front passenger side. I usually only hear it when I am moving at low/moderate speeds and turning the wheel to the left, although occasionally if the road is bumpy I hear it with my wheels straight ahead. For a couple weeks, I thought the noise only happened when moving-- however, last Friday, I was sitting in the car, which was parked on a hill with the wheels curbed (steering wheel all the way to the left). I turned the car on, and immediately the car started groaning (even though the car was in park). Then, after about 30 seconds, the gas engine turned off (I think that's what happens when the car gets much quieter after idling for a bit) and the noise stopped. SO, it happened when the car was in park as well.
View 6 RepliesMy 2006 Prius makes this noise - like a groaning sound for about 5 seconds - when I shutdown the engine. Always happens when I am NOT at the dealership. Generally happens when the engine is hot. What this might be?

View 4 RepliesGot home from work the other day, shut down my 2012 Prius 4 and went into the house. A couple of hours later went into the garage to drop a trash bag and heard a humming/whirling sound from the garage. Walked around the Prius and isolated it coming from the bottom rear of the car. Went and got key, turned the car on, then off again and the noise ceased. What that was? Fuel pump maybe? And why did this occur?
View 2 RepliesHappened to go down to garage to get something from pip about 3 hours after charge was complete and noticed loud hum coming from right rear wheel well area.
We had not had any lightning storms, electrical interruptions or anything odd; house is on whole house surge protection, and 240v evse has been working fine.
Hum disappeared when car was booted up in ev for a moment and then turned off. Hasn't come back on in an hour.

I got home today opened my door and got snaked in the face with the smell of brakes. I got out of the truck then I heard the drivers side rear brakes popping as they are cooling down. I reached down to touched the wheel and it's crazy hot. Opened the garage and went to retrieve the infared thermometer. The rotor/caliper was 350 degrees, hub was 150 degrees, axle tube was 90 degrees.
I took the wheel off and inspected stuff. The rotors do have some heat spots, the caliper visibly looks okay but not 100%. The pads look like even wear. I am guessing that the caliper either is hanging up or I have a wheel bearing going? The passenger side was like 80 degrees on everything. There is a slight shimmy while driving which to me feels to me like the beginning of warped rotors. I don't hear anything to me that screams wheel bearing noise wise.Brakes or bearings?
I have a 1997 F150, 4X4. My mechanic says its time for new brakes and was curious if it would be worth possibly converting from drum brakes to disc brakes??
My mechanic has quoted me $300 to do the rear brakes, would it be worth the extra money to convert??? I really don't care for drum brakes. I have done a search on the internet and every time it brings up the issue with the parking brake.
Getting a lot of vibration and noise when slamming on the brakes. Not like my last vehicle which was very quiet. Want to bring it in to have it checked, but if there is nothing wrong and its normal, I will have to pay them for looking at it. Always scares the crap out of me when it happens.
View 18 RepliesI just got my brakes fixed. I heard squeaking and they were rough. At the shop, they told me that the brakes had glazed. They had to machine the rotors. Mileage: 20K.
View 19 RepliesMy 2014 pip has an odd noise I first notice when pull out of the garage. When I am traveling in reverse and hit the brakes there is a loud click as if something in the suspension is shifting. Then when in drive I have the same click the first time I hit the brakes.
I also hear a metallic rattle on the highway over expansion joints. The dealer says that noise is nothing but coupled with the click under breaking I am sure some item is loose.
I recently bought a new Elantra 2012, 2 months ago. While driving it during the first month, I heard a strange vibrating noise. I went to the dealer, since it's under warranty until 2019, and they told me that when Hyundai did their recall on their Engines, the head gasket was constructed wrong and they just had to order another head to fix it.
Fast-forward two weeks and I finally got my car back. At first, it's perfect! No noise or anything, but about a week later, yesterday, it starts to make the noise again.
For my second noise, I know it's the brakes. They squeak when I stop, even though the company I bought the car from is not allowed to sell brakes >50%, I'm assuming they did anyway. The problem I have with this is that yesterday, while on the highway, the breaks made the squealing noise regardless if I was braking or not. As long as the car was in motion, it made noise. Should I be concerned about this?
I have a 2012 F-150 4x4 super crew all factory with 54,000 mi. I've noticed a new noise/hum at slower speeds, more frequent now. The noise doesn't sound like its from the front or back specifically. I pulled the front wheels this evening and the front rotors seem pretty tight, how easily should they turn with vehicle off for about 30 min? I started it and pushed and released the brake and quickly tried to turn them, very tight, after a minute or two they relaxed a little, another 5 min they seemed tighter? I sharpie mark on both inside and outside of the rotor and turned it past the pads and they are both squeezing equally ruling out binding of the slider bolts.

Today I notice that when I turn a corner I get a groan. At first I thought that maybe the springs are doing it. I sprayed them down really good with fluid film. No change.
So I had my daughter drive the truck with me standing on the rear bumper. It is definitely in the rear end. It is quiet when in a straight line.
