Prius (2010-12) :: Turbine / Whining Sound When Slowing To A Stop Especially While Braking
Aug 23, 2011
My '10 is just over 2 years old now and virtually trouble-free. But since new, I have a noticeable turbine/whining sound slowing to a stop esp while braking from 20mph to a stop. I wrote it off to the motor generator and brake regeneration - hybrid sounds. All fine and well. But I have ridden in two other '10s in the last year and they both seem to make less sounds while decelerating and braking than mine. Is it my imagination or is there something to it? I'd rather not blindly bring it to the Dealer as I'm sure it would get a "normal operation" finding.
1. Is there a TSB out on this by chance?
2. My 3/36 warranty will be up in 10 months. Is there a master TSB listing available on PChat or elsewhere (for free) to check on open G3 Prius TSBs?

Will I wear out the transmission using the engine brake to slow down faster when coming to a stop at a stop sign or light, then shifting back into D when taking off? Should I just always leave it in D unless I am driving down a steep hill?

Its been pretty cold up here and lately i find my car making a creaking sound when i brake coming to complete stop. I talked to a couple other guys in a Hyundai chat, and they said it was the Elantra frame in the cold.
Just wanted to get some others input, anything I can tighten up to make it go away, or bushings?? I am almost positive its not the brakes because i had them checked just before my winter tires went on.

I have a 2003 Explorer 4.0l 4x4 auto. Yesterday day the passenger rear tire got a flat, so I put the full size spare on, and went about my business. About 2 miles up the road is a stop sign, so I start slowing down, and while slowing down I can hear a whining thumping sound from the front of the vehicle. It wasn't doing this before the flat, but right after I put the spare on it starts to do this. It only happens when slowing down, not under acceleration.

Braking at a stoplight tonight, I had the VSC and ABS light come on. I pulled over to a parking lot and shut the car down. I couldn't tell any issues with the brakes at all in the short few hundred feet I drove to pull off. Turned it back on and the lights were no longer on.

The noise is not the usual vibrate noise that happens.
The Noise: As I brake harder to the final stop I hear a grind/bump noise. It is hard to describe. It is abrupt and quick. I don't believe it affects the braking just annoying and doesnt sound normal.

I've been noticing that when I brake more responsively, I feel a bump/notch right before a complete stop. It feels like something that has to do with the transmission.

I test drove a new 2012 Prius Three today and heard an odd whining sound coming from the car. Seemed to be from the front area, but I'm not sure. The salesman said it was "sonar," which was added to the latest models so that pedestrians, particularly those who are hard of hearing will know you are coming.

I have been working on all my wheels new pads and new ball joints in the front top and bottom. So when I am braking now I can hear a distinct whining sound kind of like a crapped out automatic tranny. I drive a manual so not my problem. I would assume a standard brake bleed will fix? The pedal is a bit spongy but it still stops like it should. I also have a grinding when I drive pretty sure it is unrelated just the backing plate touching the rotor I think.....

When slowing to a stop and turning to the right, there is a ticking sound (not loud) coming from the front. The ticking rate slows as the wheel slows and continues until almost stopped. Break pedal pressure does not affect the sound. The dealer tech heard the sound on a demo drive but they had no clue what it was and found nothing wrong.
The tech, sitting in the right seat thought the sound was coming from the left side. I hear it coming from the right side. Maybe that means it comes from the middle? I only hear it when coming to a stop. Maybe road noise covers it up at higher speed but I don't know.
Currently at about 38,000 miles.

Last winter I had a moaning sound in my front end when slowing down to a stop when the temps were around the freezing mark. When it would happen, sometimes i would engage the 4WD and it would go away, and come right back when disengaging the 4WD. I took it to my dealer and Ford's procedure was to re-pack the front wheel bearings. When I got the truck back the weather warmed up and the moaning didn't come back. When this winter started and the cold weather came back, so did the moaning in the front end when slowing to a stop.
I took it back to my dealer again, and this time they checked what I suspected all along, the IWE's for the 4WD (the integrated wheel ends). the seals were cracked, letting moisture and rust formation inside of them. After the IWE replacement, the moaning noise went away. My research has found that this problem goes back to around 2004 on up. If has these symptoms with the 4WD truck in the cold weather, have your mechanic check out the Integrated Wheel Ends. By the way, my oldest son is the Ford tech that performed the repair on my truck, so it was in his best interest that my truck was fixed .

Yesterday we were on a 10 hour trip and the engine was acting oddly; when braking, the engine sounded just like the engine brake, but the MPG indicated that it was consuming fuel (engine brake does not consume fuel). When braking, the engine would sound, and the MPG indicator indicates fuel consumption, it would go down to 50, with the heavier braking, like when stopping... then at a certain point it would suddenly stop
It seemed to happen most times but not always. This issue didn't happen before.

I've noticed more and more that when I am braking that I heard a high pitched whining noise. Sort of this ultrasonic type sound. It will only go away if I depress the brake pedal very firmly after being completely stopped. However every so often the firm press will not stop the noise. I hear it more in the evening on the way home than in the morning to work, though I may not be paying attention as much in the A.M. due to morning brain fog.
I don't hear it any other time. I'm worried something is wrong with my inverter.

Got a 2011 f 250 6.7...turbo started making a sound more like a turbine in a plane when I hit the throttle to cross the street...boost gage went to 0...i got a new turbocharger from garrett. Installed it and when I started the car there was no boost at all. I searched for any leaks and nothing. I get a code p132b.

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.

My 2013 Prius with 25,000+ miles has developed a low “clunking” sound every time I stop and the rear of the car settles. It seems to have come on gradually and now it doesn't seem to get any worse. My dealer is unable to find the cause and there is nothing loose in the back end of the car. This isn't an awful sound but it’s very irritating and I’m embarrassed to give anyone a ride. I've driven a friend’s 2010 and it makes no noise when stopping. I’m about to go back the dealer again and attempt to get a manager to take a ride and see if he can hear the sound. The mechanic I dealt with claimed that he tried out a new car off the lot and it made the same noise – implying that I should just quit whining.

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?

Oddly enough, I only get this when the car is slowing to the last few mph, say 8 and lower & while turning to the right. Straight or left it doesn't do this.
I have looked under and around the tire/wheel to see if there is a stick or something but there isn't anything that I see.
It sounds like the playing card in the spokes of a bicycle. The click slows as the car does, so I swear it is something that is coming in contact with the wheel.

A couple weeks ago I started experiencing some issues with what seems to be the ABS: when braking to a full stop, a "motor" sound appeared accompanied by vibration on the pedal; however, the ABS indicator light did not light on (although it does light on when I start the car). Several weeks later I began having problems with the transmission. It first appeared when putting the vehicle in reverse but now it happens in almost all gears. Finally, the "service engine soon" light turned on.
I took my car to the mechanic and he said the problem is a solenoid and quote a repair (includes valve body replacement and work). He claimed that the "ABS problem" is related to the transmission issue but as I explained above the "ABS problem" predated the transmission issue. My question is, does this link between ABS and transmission make sense? Also, if I go ahead and replace the transmission valve body can I be confident that I won't have any more issues with the transmission for a while? I am concern about spending more on this car giving its current trade value (I already replaced the front suspension struts, brake pads and rotor discs and new tires).

Just bought my new ride last week and already noticed strange clunk sound when braking. It doesn't happen all the time but seems to happen when I make full stop, like at a stop sign or stop before turning.

I get a grinding type of sound when I am braking but only when I come to a complete stop and then again when I release the brake. It is only for a second but it is loud and doesn't sound good. What could be wrong. It also is much worse when it rains.
