Sonata NF (2006-10) :: Rattling Noise While Accelerating

Over the last couple of days, my 2009 Sonata V6 has developed what I best can describe as a rattling noise near the engine when I am accelerating the vehicle (noise changes based on throttle input). I only hear the noise with the car in drive, if I shift into Neutral or when I am in Park I don't hear the noise when I rev the engine.

Lexus RX 2004-09 :: 2007 - Rattling / Grinding Noise While Accelerating From Stand Still?

I have a 2007 RX350 with about 243,000kms on it. I recently purchased this car and everything is great on it except one thing. As of late, I've begun to take notice that when I accelerate from a stand still (for example after stopping at a light/stop sign), a loud rattling/grinding starts and then as I pick up speed and change gears, it fades away. The sound is more rattling than grinding. As if there is a metal bowl with some smalls stones in it and someone is just shaking that. There is also another sub issue that I'm having. There seems to be a clicking noise every time I apply the brakes or even accelerate. The same clicking noise reoccurs every time I put the gear into drive from neutral. However, when I do that, there is only click as opposed to braking/accelerating, where there are many. I'm hoping this is all part of the same issue and not isolated issues.

Lexus GS 2006-11 :: Rattling Noise Inside Cabin Coming From Passenger Side

I have 06 gs300 AWD and recently it started to make that noise. At first I thought my shock/struts went bad and i had it inspect and they are good, ball joint and control arms also good. However, I do not know if strut mount is bad or not. When I go over small cracks i can hear rattles inside but when i let my windows down I hear less. I do not know if the window or door has to do something with it. It seems like coming from passenger side. Btw sometimes i do feel even dashboard rattles a bit.

Chrysler - Sebring :: 2006 2.4L - Engine Keeps Rattling And Making Noise

Engine oil has been changed and spark plugs changed. The engine is still making rattling/clicking noise. I checked with a mechanic and he indicated that engine needs to be repaired. Didn't say exactly what needs to be done and stated it would cost about $2200 for parts and labor. Why the engine keeps rattling and making the noise? Oh, before plugs were changed, the engine was shutting off at times when in idle mode.

Prius (2004-09) :: 2006 - Rattling Noise When Combustion Engine Is Engaged

My '06 Prius just started making this noise. the check engine light is NOT on. I haven't really heard this noise before in my recollection. I just got an oil change 3 days ago and when I got the oil change there was no indication from the dealership that there were any issues. The engine only makes this noise when the combustion engine is engaged. I can't see any wobbling on the belt drives or and loose parts in the engine. The spin appears to be coming from the engine block or around the pullys for the belt. My first thought is that it could be dirty gas because I first heard this sound after filling up. I am 300 miles from home and have to drive home today.

Accent MC (2006-11) :: Engine Has Rattling / Knocking Noise When Cold At Startup

so with the weather turning cooler i have noticed a new noise. i am at 34,000 miles and run synthetic oil ever 4-5k miles.

I hear a rattling/knocking noise when you start engine, not right away, but like after 15 seconds and it lasts about 30 seconds then seems to go away and is quiet again.

Almost sounds like a lifter is tapping due to not getting oil.

I changed the accessory belts a while ago and it did not first make this noise right after but maybe a few days after which coincided going from 80 degree weather down to 40 degree weather.

Could it be an accessory belt being too tight? If so, why wouldn't it make it on startup? I can see it going away as rubber expands as the warms but I would expect it to make the noise from starting till then. Not 15 seconds into running.

Sonata NF (2006-10) :: Rattling Noise Coming From Driver Side Of Engine Bay

Recently when I first start my car in the morning, there is a rattling noise, which sounds like it's coming from the driver's side of the engine bay, or possibly just under the drivers side door. It only lasts for a couple of minutes. It will increase I accelerate, and then decrease as soon as I lift off the gas. After a couple minutes, the rattling goes away, and everything is right in the world. Today I drove it around the block and parked while it was still rattling away. When I put it in park the rattling went away. I put it back in drive and it came back. Then as usual it finally went away whether in drive or park. I'm completely stumped on this one. It's an '08 2.4l GLS and has 138,000 miles.

Prius (2004-09) :: 2006 - Rattling Noise Coming From The Engine Under Acceleration Only

i have been hearing a rattling noise coming from the engine under acceleration only. It isn't a super consistent rattle, seems to only happen when accelerating from lower speeds. And sometimes you don't hear and other times you do. It's not a bad rattle or knock it's more of a ticking/light rattling sound that is definitely abnormal.

I know my brake accumulator is barking at me and the 3 way coolant valve is going bad as sometimes I get a constant pumping sound. I don't think these have anything to do with it but thought I'd mention it.

Camry :: 2006 - Random Rattling Noise Under Hood Near Engine On Passenger Side

I have a 2006 Camry LE 4 cyl. that developed a light, random (metal sounding) rattling noise under the hood, near engine on passenger side. It's present/noticable at idle and slow speed.

Car runs great otherwise and great gas mileage, pushing around 100k on odometer. Out of town with car otherwise would have looked at. Could something just be loose? Something in air filter? GF drove it down to FL and was fine before she left.

Sonata NF (2006-10) :: Slight Engine Rattling Noise At Idle RPM In Gear Or Park

I have a high milage (210K) '07 2.4L which has a slight engine rattling noise at idle RPM at cold and operating temps, in gear or park. It is a fairly constant noise at idle but does vary a little. Otherwise, engine/tranny operate beautifully with no obvious problems.

I am concerned this could be a timing chain/tensioner related issue although I also wonder if it may be some other component. I have not been able to determine the source or location of the sound.

Celica :: 2004 GT - Rattling Noise When Accelerating At Low Speeds

I have an 04 celica gt with around 168 k miles on it. Recently I have noticed a distinct metal on metal rattling noise whenever I accelerate at low speeds. It seems to be my exhaust as when I rev it up in park it makes the noise. But it doesn't ever make the noise when I'm on the expressway or cruising at back roads speeds. When I got under and looked at my exhaust everything looked normal?

Golf IV / Jetta IV :: 2003 VR6 - Rattling Noise / Clunk When Accelerating

I'm new to the VW family as a couple weeks ago I purchased a 2003 VR6 Jetta. So far I LOVE it and it's been by far my favorite car I've driven. About a week ago, I was visiting my parents back home (I'm a college student) and when I went to turn on my car to go back to school I received the alternator workshop message. I didn't want to take the risk so I took my sister's car back to school and my dad took my car into a local mechanic during the week.

Unfortunately, the mechanic we took the car too does not specialize in European cars (They're just a general mechanic/Ford dealership), but we didn't want to take the risk of driving a car with a potentially failing alternator to the closest VW mechanic (About 40 minutes away). The car was repaired and a new alternator added. All was going well, but I began to notice a slight "clunking" noise when first accelerating/lifting my foot off the brakes. I didn't think too much of it and it wasn't very loud nor severe. To me, it sounded like the interior plastic shifting when I moved.

Anyway, here I am a week later and I'm noticing a lot of noises that didn't exist before, including the clunk I just mentioned. I took a few audio recordings. (For the record, there is NO CEL or any dash lights currently on, thus why I'm not as concerned).

The first audio: [URL] ....

In this link, I'm driving the car around the parking lot in which I park my car here at school. It's mostly bumping gravel, but at the time of the recording I was driving very slow. You can hear a squeaking noise.

The second audio: [URL] ....

In this link, I'm revving the car while parked. Something I've noticed that it didn't used to do is rattle while idling ever so slightly (It's not audible in the recording), but in the recording you are able to hear a slight clunking noise.

Toyota - Highlander :: 2010 - Rattling Noise At Approx 20 Mph While Accelerating

I have about 72k miles on my Highlander, which we purchased certified through a dealer in May. At the time of purchase, we noted an intermittent rattling noise, but didn't think much of it. It has increased in frequency and in volume since that time. I have had it to the dealership four times now to have it fixed. They have replaced the heat shield on the exhaust, tightened my license plates and today replaced my catalytic converter (at no cost to me) Imagine my dismay upon driving home and again hearing the rattle. When they decided the rattle was related to the catalytic converter, they were essentially banging around my car with the handle of a hammer and trying to replicate the rattle...needless to say, I am a little concerned that the techs are unable to determine the root of the problem, much less fix it. It seems to be correlated to some degree with a certain RPM. It sounds as if something is loose somewhere, but that place is a mystery to at least four different techs (all of whom I have driven around so that they could hear the sound and who still cannot identify it).
