I have a 07 Hyundai sonata that has a rattling noise only during acceleration and only at just under 2000 rpm's. I went to a mechanic who checked the heat shields and exhaust only to tell me it was in the transaxel and sent me to a transmission shop. the transmission shop told me they think its the hydraulic lifters, and sent me elsewhere.
View 1 RepliesI have a 2008 Hyundai Sonata GLS 2.4L with 131,000 miles on it. When I accelerate from a stop, there is a buzzing/rattling/grinding noise coming from the engine bay of my car. It's really hard to describe, there is a definite buzzing sound, but also almost like there is a bolt rattling around and banging into things. This only happens for a couple of seconds. It also seems to be worse when I'm accelerating up hill. If I accelerate slowly from a stop, the noise does not occur, and it also does not occur if I accelerate while I'm already moving.

I am hearing a ticking/rattling noise from my engine around 2k-3k RPMS. Anything before or after that, the noise dies down. I could hear it from the interior of the car as well. I at first thought it was valve chatter. Someone said It could be a piston or rod. What parts will be needed? Worst case, ill just swap in a 03+ 1ZZ or go with a 2ZZ.

So i noticed recently, last month or two, a rattling noise coming from either rear of engine or in dash that only happens when at the higher rpms like 4-6k rpm. It goes away once rpms come down.
I am thinking just something in the dash is vibrating a little. No other issues as far as i can tell.
It is very slight, almost sounds like a plastic food wrapper getting crinkled in there....
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.
I have a 06 sonata 3.3L v6. I have been having misfire problems and lack of power under 2000 rpms and at idle when I am either a stop or just warming the car. What is happening I feel it shake and feel the misfire but after it gets up after 2000 rpm at highway speeds its completely fine. It struggles getting up to speed if i press on the accelerator. I have changed the spark plugs and all the ignition coils maybe about 2 months ago, I have also have changed the camshaft position sensor for the rear bank. I believe that it could be the crankshaft position sensor but I want to make sure....

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.
View 6 RepliesLately I have been hearing a rattling noise from the bottom of my car, when it's in park I can barely hear it but I know its there, but when i put it in drive or reverse it gets worse. Could it be that the exhaust heat shield is loose? Or worse? I had my Tranny fluid flused at 142,000 mi i'm at 144,000.
View 9 RepliesMy car just hit 111k miles last week! I have the 2006 sonata V6 LX, new spark plugs n new cats at 65k. So today I got to school for my final and realized the car was making a weird noise.
The noise is barely there on low revs, but when I rev a tiny bit it becomes very noticeable, and gets rattles faster to a certain point, but i think after like 2.5-3k revs kinda goes away(kinda because I don't know if its because i cannot hear it over the engine noise) and then when i let off it rattles on the rev down and then gets silent for a split sec and then back the low rev rattle.
What i understand it could be belts, pully's, the timing belt tensioner?
I have the 2006 v6, and so i think the seal for the front of the engine has issues for the year, so there is an maybe very slow oil seeping thru, it had stained the front left of the engine above the alternator, but has been like this since 50k miles when i first noticed it and no problems
And also i have 2 12" 1000w rms subs in the trunk, so could it be the alternator that can make that kind of noise?
Recently my engine started making a rattling noise. It does not matter if the engine is warm or cold. In either condition it produces the same noise. The noise can be best heard at the back of the engine. My car is a Sonata 2.4 GLS from 2006 and has roughly 110000km on the odometer.

Tomorrow I'm dropping the car off to the dealer in hopes that they can find it.
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.
View 9 RepliesI 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.
So, I changed my spark plugs a couple of months ago and did the pcv valve swap as well. Now I have this high pitched rattling noise, like a tiny chain rattling. It is coming from the engine bay - in the area between the throttle body and the firewall. At least that's where I can hear it.
It does it quickly right after I start the engine (though I am certain it is not a timing chain issue)...I had that fixed a while back. Also it doesn't sound like the timing chain tensioner noise.
I am thinking maybe the pcv valve that I swapped out. I remember reading that a new one should make some noise when you shake it...an old, gunked one would not rattle if you shook it in your hands. Consequently, this noise sounds a lot like if I would shake the pvc valve back and forth very fast.
It happens intermittently on idle....and when I rev the engine, it will also make the noise while the RPM falls back down. Since this happened literally right after I did the spark plug change and the pcv valve, my guess is it's that. Maybe I didn't install it correctly.
My 2010 Sonata GLS recently started to emitting some noise during acceleration, seemingly come from under the hood. The noise is most noticeable between 15-25 MPH, and is more noticeable when I go uphill. The noise also becomes more frequent with higher speed.
I have a shared m4a file with the noise recorded on Google Drive [URL] ......
I've got a Sonata NF 3.3L I bought for my first car. Bought the car second hand with 119,000km's. Runs really well but in the last few months there has been a rough sound on acceleration. Sort of like a ticking noise. Doesn't matter if it's warmed up or not. At cruise speeds you can't hear it. What it could be? Ran some injector cleaner through it to no avail.
View 2 RepliesI came across this issue in my Sonata Turbo. At 5K+ RPMs, I can hear a sort of gurgling/rattling sound coming from the engine. Its concentrated on the driver's side behind the firewall. It goes away immediately once I drop below 5K RPMs. It isn't too loud; I didn't notice it up until now because I usually have some music going.
This is my first Turbo that I have ever owned. That would make sense because it only engages at high RPMs. My car has 3K miles on it. Been loving it so far!
I have a 2011 GLS with about 47K.
There seems to be an issue with acceleration around 50-65MPH as the RPMs will jump as if to hesitate between gears (just my assumption). Maybe driving style/conditions as I live in West-Central Florida?
I'm the original owner and we have two of the same vehicles.
My 2003 Ford Explorer, Eddie Bauer 4WD is making noises when the vehicle is at 2000RPMs. Below or above 2k RPM's no noise. Sounds like a very angry rattle snake. I seem to drive at speeds that require it to be at 2k RPM all the time. So needless to say as fall is approaching and I have the windows open, my hair is now falling out and not blowing in the fall air. I want to get it looked at, but don't know what to tell the mechanic to look for.
View 2 RepliesMy wife has a 2000 Pontiac Grand Am, as seen above. The car recently started having issues, especially when cold, where the RPMs will rise when in gear but the car will not accelerate. It happened from 25 mph and lower while in a subdivision as well as around 45 mph on city streets. I have a feeling this is a transmission issue, but don't have much experience when it comes to transmissions.
View 6 RepliesI've got a 2012 GLS manual with about 400 miles that now has a noise that concerns me. At just over 1500 rpms there is a rattling noise that sounds like its coming from the rear and underneath the vehicle. It sounds like metal vibrating. I think it could be the exhaust but I am not sure. It didn't do it on the test drive and it is fairly intermittent.
What it could be and if it might be normal? Should I take it in and get it checked out or would that be a waste of time?
Noticed a light rattling noise during acceleration? It only seems to do it at lower rpms then stops? I feel like I remember reading something about the wastegate causing this? but I don't remember where i saw that?
