Prius (2010-12) :: Clunking / Banging Noise When Starting
May 30, 2016
Yesterday I started my 2011 Prius, about 3 seconds later (Im guessing here) I pushed the A/C button, the engine started (at the same time), and I got this horrible grinding, clunking, bucking noise from under the hood. It lasted for about 5 seconds then stopped and everything was fine. Engine ran smooth, A/C was running. I turned off the A/C thinking that might be it and started it again, again everything ran smoothly. I pushed the start button the shut down the car, waited about 15 seconds, pushed it again, all normal, again with the A/C on. I put into drive and moved forward, allowed the engine to start, no problems. Smooth operation, everything normal.
I gather it'd be a good idea to take it in, but want to know how many "on-off cycles" until a problem is erased from memory. I did drive it last night (everything ran just fine) and went through 3 "cycles". What this could be? Bad fuel?? I have a 2011, with about 38k miles on it. This is the second Prius I've owned and have never had a problem before, let alone something like this.

I have recently noticed that when I accelerate my Toyota Prius 2010 it makes rattle noise and vibrates the whole car. The weird "bang" "bang" noise comes from the passenger side near the engine and when the noise comes my whole car shakes like crazy!
I went to my local car mechanic and he couldn't find anything wrong with it accept the EGR valve which I have now replaced. However, the problem still continues. When I shut down my car and then restart it its fine for some time and then the problem repeats!
It sounds like this .....

Brought mine to the dealership they can't find the knocking noise. I asked the technician to Test drove it but still can't find the problem. Technician on the passenger side and we test drove it. He was able to hear it, but can't confirm if its coming from the pads or rotors. Its pretty anoying when driving at night when the roads are quiet. You can hear it even with windows close.

We're having problem with our Prius where car suddenly started to make weird clunking noise from the engine (28k miles, 2011 Prius). Car sounds unsafe to drive around, so I left it parked in the drive way. I did check engine oil level and it was at F level.

Having issues with Gen3 Prius steering column? I suddenly developed this clunking noise when I rock my steering wheel from left to right. It's steering correctly but I've never heard this noise before....

This bad squeaking, loose rattling and (sometimes) banging noise from the left rear started happening about a couple weeks ago. I've removed all interior panels, even the exterior bumper thinking there was something loose and nothing. I suspect as a last resort it has to be the suspension despite the car having only 17k km.
What is strange is the rattle increases in sound volume and occurs more often the longer you drive and also if temperatures get colder.
In other words, if I have the car parked in my garage overnight (slightly above 0 C) and immediately drive next morning into sub-freezing temps and on bumpy roads, you don't hear it. But after 5-10 minutes of driving, you start to hear it and gets louder and more frequent.
Searched other threads and some have reported the shock as the problem for 2010/2011 models, but none had any sound or video to compare.
The video shows how bad it is : [URL] ....

I drive a 1992 325is,(auto) with 150K... a few weeks ago only when racing or hard acceleration there was banging or clunking, coming from under the E-brake area, almost sounded and felt like the back tires hopping up and down as if i where chirping gears in a riced honda. The tranny IS NOT slipping or banging etc.
Now over time it has progressively gotten worse, it started doing it when rpms jump, now i cant even accelerate, I have to feather the gas OH SO lightly or else, it clangs and bangs almost sounding like the drivetrain is slapping against the chassis. i have to accelerate extremely slowly, and lightly or else it clanks and bangs, it takes me 5 mins to get to 40mph. Can it be the guibo? or mount that keeps the drivashaft in place?

My wife has a 13 Prius persona. There is a rattling/banging sound coming from the front end on drivers side only. Car has not been in any accident. Toyota dealer has looked at it twice. First time could not hear noise. Second, he heard it. They looked at everything and then stated that it was the ABS Brakes testing. It sounds like something is loose- that is the best way to describe the noise. It happens fairly often, too. Never happened with my 2012 Prius model two when we had it.

The car is under 25k miles. I have owned for less then 2 years. Recently, I notice a noise coming from the rear every time backing out the drive way. The sounds louder in the winter**. I have gone to 3 different dealers and non of them offered a remedy. Some say they cant reduplicate the issue so I scheduled a test drive with a tech. Was able to duplicate the issue, however the tech says its normal ( pad shift over time) and told me a lot of the newer carmy has the issue. I'm exhausted from going dealer to dealer and no remedy issue. They all said the same thing "its normal & there's nothing they can do".

Our 2012 Prius with now 17,000 miles in 8 months has developed a clunking noise when turning the steering wheel, especially far to the right at low speeds.
The first time the dealer identified it as a failed intermediate shaft and replaced it under warranty. Shortly after we told them it was starting to make the noise again, but they claimed they couldn't replicate the sound and anything they heard was normal 'linkage' (whatever that is). Shortly thereafter the clunking progressed so we took it in for now the third time, and they confirmed the problem, spoke with Toyota who said we must have had a bad part, and replaced it again.

My 2010 has the intermittent noise when starting in the cold. Brought car to dealer with printout of the TSB from December and they will not repair it unless they duplicate the noise. Also I read about a rear motor mount to be replaced.

The noise seems routine. It happens when you get close to the car and open your door. I guess the car is anticipating that you will start the car soon and under the hood, some subtle mechanical noises occur. Just wondering what that noise is?

About a month ago, I purchased my 2013 Prius Four. I've put on about 2,500 miles so far and recently started noticing when I start the car up, it is giving off a high pitched squeaking noise. This happens both when the car is using the electric battery and when I can feel the gas engine kick in. After about a minute or two, the noise goes away and doesn't come back.

I was on the way to the airport in my 2004 Hyundai Accent last night when a loud thumping/clunking noise starting coming from the rear end. At first it sounded like a flat tire or something stuck in the tire so I stopped to inspect but everything looked good. I continued my trip as the noise continued to get louder but made it home. I worked on the car for several hours today and have not had any luck nailing down the cause. The sound appears to be coming from the drivers side rear tire area and would get much quieter when I turned right. It sounds like a spot on the wheel is hitting something but I don't see any area that shows signs of wear. Things I have checked:
- Jacked up back end and spun both tires, both spin with no noise and have no play.
- Removed both rear drums and inspected but all looks good.
- Inspected all rear end suspension bushings but don't see anything that stands out.
- I did notice the strut on the drivers side has some play where the passenger side is tight but when I rock the car up and down I hear nothing.

I've a 2007 Toyota Camry (LE 2.4 L 4-cylinder). Couple of days ago I tried to start the car and I heard this banging/grunting sound as I started the car. And, after the car started the engine is running much louder. Oddly enough when I got out of the car and opened the hood the noise didn't seem that loud. In other words, it sounds louder from inside the car than standing outside with the hood open.
Before all this, the engine ran very smoothly and very quite. Here is a link for two audio files that captures the sounds. Note that I recorded these two clips from inside the car.
First when is when I'm starting the engine (the sound can be heard at around 6-7 seconds): [URL] ....
Second is when the engine is running loud (I'm not driving the car...just sitting there letting the engine run): [URL] ....

first off my truck is 2001 ford ranger 4x4 with an auto. transmission. when I'm driving around in 2wd, everything is fine...
when my 4wd high is on, and I'm starting from a deadstop my truck makes a weird "clunking" noise in the front end. If I'm stuck in mud or snow, and I give gas it keeps "clunking". where the problem comes from?

Every time I turn on my 2010 impreza and slowly drive away i hear a clunking sound coming from somewhere in the front. it happens almost every time i start it up, even if it is warmed up.
Went to the dealer (car is 4 weeks old) did a test drive and it only did it once for them of course even though we tried almost 10 times. What it could be and will take it in for a full day to let it get cold.
Also, a slight rumbling when the car is cold and the blue cold engine light is on? I know the car being cold explain that but you'd think that a brand new car would be free from things like that.

My concern is I have some intermittent clicking/clunking noise. What causes it is if I start out whether fwd or rev. Or if I am going slow in 1st gear and I let off the gas to slow down or press the gas to speed up (btw 1000rpms and 2000rpms) I was told this noise is the clutch engaging or disengaging, which doesn't make sense because when it happens the clutch is fully engaged.
I have had this noise before 2X and there were things that were loose, which were tightened up and the noise went away. This time local dealer told me sound is normal and to keep an eye on it. To me it doesn't sound right cause its noises I didn't notice before.

For the last few weeks (about a month) I have been experiencing a clunking noise/ knock on acceleration coming from either in front of my feet or below my feet (drivers side) ONLY on acceleration and only then from a full stop. I can also feel the clunk as well which leads me to believe it is a transmission mount.....maybe an engine mount. I am taking her to the dealer after work today. we had some very cold weather and I was hoping it was just ice but yesterday and today were well above zero and it is still there and it is EVERY time I accelerate. Which is a somewhat good thing since I will be able to replicate the problem for Hyundai.....

I have been frustrated with my Elantra's handling from the time I purchased. I feel that the car is setup poorly and has design/OEM part issues.
I have improved the rear-end "hop" issue by replacing the OEM rear shocks with the KYB Gas-A-Just's -- a big improvement in handling the bumps. But the rear-end solid axle on such a light car is just crap...
I have developed quite a bit of 'clunking' noise in the front suspension.
I am considering replacing the front-end shock-strut assemblies with KYBs -- I'd love to hear if it made a big difference. Also wondering if I should change-out the 'sway bar link' while replacing the shock/struts.
I'm just so frustrated with the way this car handles (I've driven Subaru's, Honda's, and VW's) compared to other cars. I feel it's a combination of low-quality OEM suspension parts, rear solid axle, light weight, crappy electric steering settings, and tires that are too wide and too low-profile for such a light car. (I have the limited with 17 wheels).

Driving 2012 Elantra with 29K on the Meter in AZ with temps at 105 degrees. I am getting a clicking clunking noise. Dealership said Strut mounts and replaced them. Drove it off the lot and the noise was still there. Wont go back to that dealership. Creaking clunking noise more frequently now and has shifted from the passenger side to the driver side predominantly. End links? Axles? Brake assembly, Hub? I first heard it when I went over a speed bump at 3-5 mph. Now it can be heard upon acceleration-deceleration, deceleration in neutral with brake only gets the loudest clunk on the Driver side. Ultimately its now constant on turns, bumps, rough roads & even smooth roads while changing lanes. What is causing this.
