Prius (2010-12) :: Loud Noise When The Engine First Started Up
Twice in the last month, my 2010 Prius has made this incredibly loud noise when the engine first started up. The noise continues for a minute or two, and then stops. The car then runs as normal. I brought the car to my dealer, who after a brief looking-over could find no reason for it. I shot a video of the car making the sound the 2nd time it happened and brought it to the dealership with me to play for the mechanic. No one who heard it there ever heard anything like it before.
It has been really cold here this winter, so "cold oil" was once thought, but was dismissed as unlikely. The car gets 0-20 oil.
Prius (2010-12) :: Engine Kicks In And There Is A Loud Exhaust Noise
When the battery power is low, the engine will kick in and then there is a loud "exhaust" sound. Are those really sound from the exhaust or some other fan?

So my 2012 plugin was parked for about 3 days, and when I turned it on, heard loud knocking and the check engine light came and stayed on.
When switching the car on or off, I'll hear two taps/ticks that were not there before. Loud knocking is not there now.
What can the issue be? It was very cold and snowing.
Prius (2010-12) :: Makes Loud Rattling Noise As Soon As Engine Kicks On
I got in the car today and started it... I was waiting a few seconds for someone to get in the car (it was in the garage) and as soon as the engine kicked on there was a very very large long rattle noise i immediately turned the car off. Waited again and turned it on same noise.. the only thing I found was a cover under the car towards the front was really loose. ( I haven't hit bottom or anything while driving) but I did have the lighted door sills just installed the other day. But it never made that noise..
btw i have 1100 miles on it..I looked under it and is the black dust protector thing supposed to be loose like if I push on it I can make it rattle..
Prius (2010-12) :: Clunking Noise When Braking
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.

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.
Prius (2004-09) :: 2006 Engine Noise - Loud Fan Like Buzzing / Especially Loud On Highway
For the past few months I've been hearing a loud fan-like buzzing noise coming from the passenger side of the front of the car. I don't know that much about cars, but it almost sounds like the engine is racing or something is spinning too fast. It has gotten increasingly worse, and seems especially loud at high speeds on the highway.
It is not the heating/cooling fan - the noise is present when the heating/cooling system is turned off.
Prius (Gen 3) :: 2010 - Clunking Noise When Turn Steering Wheel From Left To Right

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".
View 2 RepliesPrius (2010-12) :: Clunking Noise When Turning The Steering Wheel - Replaced Intermediate Shaft 3 Times?
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.
Prius (2010-12) :: Very Loud Noise At 333 - Bad Wheel Bearing Or Just Tire Noise?
My girlfriend and I just bought a 2011 a few weeks ago. We test drove it a couple times ourselves, and had our mechanic take a look at it and drive it also. Everything looked and sounded good. Not sure how much it matters, but it's a Certified Used as well.
A couple days ago, returning from a 45-minute drive which included some short stretches of gravel road, I noticed an oscillating sound. It's definitely not a noise that was there when we bought the car. Unfortunately, my cell is apparently bad at capturing audio, so hopefully my description will be enough.
The noise is very faint, almost inaudible, at low speeds. Between 30 and 35 mph it gets much louder, peaking at about 33. There's some vibration through the accelerator pedal also. Above 35, it fades pretty quickly and I can't really hear it at 50. The sound itself is 3 beats on, 1 beat off, about every second. There's a slight difference in pitch between each beat.
If that isn't enough to go on, let me know and I'll give the recording another shot and upload it if the noise is audible.
Prius (2010-12) :: Loud AC Fan Noise
I have a 2013 Prius with 41K Miles. When I turn on the car I can hear the Air Conditioner Fan (my opinion) a bit louder than normal. I know it's the A/C Fan because when I turn off the A/C the sound goes away. It makes a weird Zoom sound, but louder than my previous cars and my wife's car.
View 9 RepliesPrius (2004-09) :: Master Warning Light / VSC And CEL - Clunking Noise When Engine Came On
Today we had the oil changed and everything was good, drove to the hardware store and when we came back I put a heavy box of tile in the truck (I set it down hard, it was heavy). We then started it up and backed out and noticed the master warning light along with the vsc light and check engine light. I stopped it and checked the oil and all was fine. Started it back up and lights still on. I drove it across the street back to the oil change place and when we got into the parking lot there was no gas pedal. Pushing it all the way to the floor and it barely made it into a parking place and the battery on the mfd showed 1 bar.
When we restarted after a few minutes and when the engine came on it made a clunking noise. The guy from the oil change place came and cleared the codes. I didn't write them down like an idiot. After the codes were cleared it started fine with no noise and ran around the parking lot fine and has run perfect since (8 miles). I forgot that we put gas in as well in between the oil change and hardware store. The gas cap seemed fine. Is it possible the slamming of the box of tile caused a fuel pump inertia switch to cause all this? Could a loose gas cap cause this? It has been perfect since we bought it new with zero problems till today.
Elantra MD (2010-15) :: Loud Engine Knocking Noise
My car has 63 000 km and engine is making loud knocking noise all the time. Dealer took a quick look and he asked head office. Now he wants to run some tests to see which valve is bad. He's hesitating between repairing or replacing the engine. I'm really disappointed of Hyundai quality. I really hope that I get new engine instead of poor repair job.

When driving, getting up to about 30 mph, a loud clunking noise and feeling seem to come from under the center armrest. I have looked underneath to see if something came loose or was missing, but nothing looks out of place. Increase in speed makes it get worse.

Sonata NF (2006-10) :: Loud Clunking Noise When First Put The Car In Gear
I have a 2006 Hyundai Sonata that is making a loud clunking noise when I first put the car in gear. I start the car, put my foot on the brake, put the car in R and I hear a creeeeaakkk, clunk! noise coming from the front, passenger side of the car. I back up out of the driveway/parking spot, put the car in D and get a slight clunk! noise out of the same area again.
At first, I thought this was maybe a ball joint or a tie rod failure, but a friend of mine and I took the front wheels off of the car this past weekend and I gotta say, everything was found to be in solid shape. Nothing loose, bushings are in good shape, boots are in fantastic shape, no loose wheels that can be moved in ways they shouldn't move. After getting the noises and clunks to happen again, my buddy's opinion is that it's my transmission having a tough go of it and that I should take it to a transmission shop. Is it a transmission thing?
2006 Sonata, 6 Cylinders, 141,000 miles (227,000 km)
Never did anything with the transmission fluid since I've owned the car. I bought it in 2010 when it had 80,000 miles (129,000 km) on it.
Golf V R32 :: Loud Clunking Noise In Rear Happens Over Bumps
There is a clunking noise coming from the rear of the car. Not a metal on metal sound. Sounds like its more on the passengers side. I replaced the swaybar linkage ends since they were a little loose and thought it was that. Nope...I have H&R coilovers, they are about 5 years old. Can't imagine they be shot this soon. Had someone drive my car while i was behind the R and the rear wheels aren't dancing at all, a common sign of a blown shock. Push down on the car, shocks still respond like they did from day one. I've put the car up on a lift, both sitting and wheels dangling. With the wheels dangling, I grabbed onto the shocks to see if there was any play in the upper shock mounts, solid. Looked under the whole car for loose plastic covers. Can not see anything loose. I made sure everything inside the hatch, including the battery is sitting snug.
The clunk happens over bumps, with or without the brakes on and is loud enough that if the radio is on, it can still be heard.
Ford - Explorer :: 1997 - Loud Clunking Noise From Under The Car
I've got a 97 explorer xlt 5speed.... When you start the truck and start driving... its making a Loud clunking noise from under the car... at first we thought it was the gear box but then after replacing with a reconditioned gearbox and transfer case it was still there... it is doing this in auto mode and in 4x4 mode... during city driving it does it all the time .... but when you drive it to 100km/h the clunking completely stops.... and then you can bring the car to a complete halt (without turning the engine off) and start driving again and the clunking is still gone... BUT as soon as you turn the engine off and on again (even if only for a minute) the clunking returns again until you drive to 100km/h and then it stops again.
View 2 RepliesPrius (2010-12) :: Made A Loud Clanking Noise?
2010 with 61000 kilometers.
Yesterday morning it was a rainy and damp weather around 3-4 degrees Celsius when I started my Prius. Usually I start it up, get out and have a cigarette or something before driving so that the ICE has a minute or two to warm up. Immediately after the ICE fired up I heard a very loud clanking and vibrating sound. I immediately shut the car down, checked all fluid levels and read the codes. No codes, no warning lights. Fired it up again, same thing. This time I opened the hood and went to see what's going on. The ICE made this noise and vibrated like hell. After a few second though the clanking and vibrating slowly went away and it started to sound normal again.
Scared the living crap out of me! This hasn't happen before or since. I had like 2-3 40km drive cycles after that on the same day with no problems. The day before I had to move the car just a bit, and when doing that the ICE came on just before I turned the car off. No codes, no warning lights. First thing that comes to mind was a misfire that vibrated the engine like crazy, maybe due to the damp weather effecting spark plugs or a flooded cylinder that was due to the only a few seconds of engine running the day before.
