Prius (2010-12) :: Engine Making Noise In Park While Running?
Jan 21, 2011
My wife bought a new 2010 Prius Hybrid. It has consistently achieved 51+ miles per gallon. She bought it in June-2010 and at the 7000 mile mark (October?) called me concerned about a noise it was making under the hood. She described it as akin to the noise a playing card made when as a child you fastened it to the spokes of a bicycle. Chattering? It lasted 15-30 seconds and went away, before engaging in reverse or forward. A trip to the dealership was fruitless, an "intermittent episode" the diagnosis.
Now, nothing since until today. Same noise again, 12,000 mile mark, goes away in same timeframe, in park. Only today, through the course of several errands, her dash MPG indicator reads 39 MPG. She is waiting as we speak in the dealer lobby as they plug into the computer hunting for fault codes, etc. Having issues, especially an indicated dropoff in MPG seemingly in conjunction with such a noise?

I just bought a new 2015 prius a few days ago. After a couple of days of driving it around, I noticed this clunking noise that lasts about 2 seconds while the car's shutting off its gas engine when the vehicle is at a complete stop. It happens more frequently a few minutes after I started driving the car. When the car is coming to a stop and the 'EV' light is not on yet (only 'ECO' light is on), after the vehicle's made a complete stop, I start to hear this clunking noise (it almost sounds like the noise you hear when you press down your emergency break).
After this noise, I feel the vibration and hear that the gas engine's shut off. I talked to the dealership and they hopped in to hear that noise, and as always, it didn't happen. But as soon as I left the dealership, I hear it again. the car is normal when 'EV' light is on when its coming to a stop (no abnormal noise), but its only when the gas engine shuts off after the car has made a complete stop. And the noise is even louder when the vehicle is on a slope, either uphill or downhill.
I uploaded the video file ....

Recently I started to hear engine pinging/knocking-like noise when the hybrid battery level becomes low like two bars and the car starts a charge cycle. I also hear it occasionally when I accelerate on uphill. Is this normal or should I take it to a mechanic?

My '03 passat w8 just started making a lot of noise which sounds like the engine fan is running very fast and blowing like mad even though my car is not warm. It started 3 nights ago and sounds like a street sweeper, which is what I thought it was until I looked around and saw there was no street sweeper to be found. When I turn the car off the noise winds down and disappears with the fan still running just making the normal amount of fan noise so I don't think the problem is the actual fan.

My 2.4L engine is making a clanking noise while running. When I checked the oil level today, it was low by about 1.5 quarts. There's no check engine light.
Car has 74K miles now. I purchased the car two years ago with 35K miles. I have always performed regular maintenance myself. The car had its oil control valve replaced at 55K miles.

I have a 2006 Chevy Malibu 125,000 miles, 2.2 Engine that was running sluggish, noisy like needed oil (checked didn't) and check engine light was on. Took it to a repair shop and told needed an oil change, car still ran sluggish, told to drive it a day or so. Two days later, car wouldn't go over 50 mph, took it back and told needed air filter and mass air flow cleaned. After they did that, they told me the Catalytic converter needed replaced however they don't do that work. Within a week car would not run so had the cat replaced.
Car ran better but still not great. Took it to another place, spark plugs replaced, throttle body cleaned and fuel injector cleaner added to gas.Still the car ran sluggish and was making noise and check engine light was on. Took it to parts store to have code checked on check engine and said error in bank one of oxygen sensor. I replaced that, reset the light and am sure you know, it still runs bad and noisy and check engine light came back on. I am losing power on hills and big hills the engine rattles.

I have gone through several threads about A/C noise some saying its the compressor - others saying it is normal but I don't remember my A/C having this kind of noise. It doesn't matter what the ambient temperature is but it makes this noise, every time. I uploaded a video to youtube so you can hear it clearly. Any time the A/C button is pressed, the noise is made. The fan can be set to high, turn the A/C off and noise instantly goes away.
Also - A/C still blows cold and my fuel mileage hasn't changed much if any.

My son took my Prius to drive to his National Guard base and the Prius started to make a dragging noise. What is this and what can he do? There are no Warning lights or anything else.

We have a 2010 RX350. It makes a noise at a strange time. While in the garage with the engine off sometimes it makes a humming noise. The noise can last up to five minutes. It sounds like it could be coming from the back but not positive. The car has not been operated for several hours when the noise occurs. If I start the engine and immediately cut it off the noise goes away. I know that it will never do this if I take it to the Lexus dealership.

For the last couple of days I have noticed that I have water dripping from the engine area of my after I park or stop. The dripping appears to stop after some duration (usually don't wait to how long it persists) but I don't recall seeing this the earlier in my ownership (first 12 months of owning 2010 Prius). It clearly appears to be water as it has no color or scent and when it dries, it leaves nothing behind. The only change that comes to mind is that I have been using the front defroster which I did not use before. It is not due to using the air conditioning, as I don't use it during the AC during the winter months at all.

One thing that brought me here is the noise of my liftgate when being closed. When the liftgate contacts the latch it makes a rattle-y/loose sound. The trunk is locked and secure however the sound is very off-putting. I bought my 2010 Prius II as a CPO last year and never really thought much about the noise, only that it didn't sound very pretty.
However, I was recently sideswiped and was put in a 2013 Prius II and the liftgate closes with a solid thunk with no loose rattles. What could be causing this squeaky/rattle sound? I thought it could be my license plate frame since rentals typically don't use frames, but it seems really unlikely.

I just got back from Town and Country Toyota charlotte, NC. They did my oil change and tire rotation. I also told them the rear spoiler is loose and making noise over bumps, they ordered a new one under warranty. I also wanted a new driver side wiper blade, they also are ordering a new one under warranty. So so far they are doing a good job. I have been there one time before.

I bought a CPO 2010 Camry LE (2.5 4 cyl, 6 sp auto) a few months ago. The car had around 34K miles when I got it, and ever since then, it has had a high pitched whining noise when accelerating or revving the engine in park. It is noticeable from around 2500RPM up, and seems to be a little louder when the engine is cold.
I have left it at the dealer twice, and both times they have come back and said it is normal. I can't believe this, because I have owned many cars over the years, most of them being fairly dilapidated, yet most of them haven't had a noise like this. I think I have read a comment online somewhere that an issue like this was found due to a bad power steering pump .

2010 F150 XLT 4.6V .... Not too long ago my truck started making this whining/roaring noise when I accelerate. It does not matter what speed I am going from the slowest to the fastest it makes this noise but it does not make it when it is idle or at least it is not loud to the point where I can hear it while inside my truck. I am not sure what this can be I am at about 51,000 miles and have no problems other than the noise besides the fact that to me it seems as if it pulls at times when I drive it but others say they don't feel it pull. So I am not sure what is going on and I do not want to take it to any mechanic I'd rather fix it myself and know what is going on with my vehicle?

Yesterday, while at the store. I started my 2004 prius and the engine was making some crazy knocking noises. I went to auto zone and pulled the codes. It said random cylinder misfire and misfire on cylinders 2,3, and 4.

So I have a 2012 Elantra Limited. From what I understand the power steering is no hydraulics and is only electric assist. So I have a strange problem. I can remember in previous cars when a power steering pump was going bad it made a whining type noise that changed with engine speed. My Elantra is making the same type of noise. I'm trying to track this down. My car doesn't have any other symptoms aside from the noise. It's hard to really tell but it does appear to be coming from the belt side of the motor (passenger side).

My 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?

I've decide to replace the engine in a 2005 Prius. For whatever reason it went bad around 110,000 miles. It was making some noise and then went all at once. I don't know the complete maintenance history of the car, but I know it was pretty regular. I also know the car was driven mainly highway miles and on A LOT of dirt roads. So, the oil may have needed more frequent oil changes.
