Sonata NF (2006-10) :: Slight Engine Rattling Noise At Idle RPM In Gear Or Park
Sep 22, 2015
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.

2007 Sonata V6 with 72K miles.
The car has developed a rough idle while in gear (i.e. when stopped at a stop light) and park (i.e. after I start the car).
It's starting to get a little annoying since I'm used to a very smooth idle.
I think this issue started within the last 2-3k miles.
Plugs were allegedly changed at 30k. A full tuneup was done at that time.
Wires are still original.

Lately 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.

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.

2006 Sonata 2.4. A couple weeks back I posted about how my engine is making a slight ticking noise. It makes the noise consistently. I recorded a video of the noise. What it could be. Here's the video: [URL] ....

I have a 2006 hyundai sonata 3.3L V6. Only happens on a cold start. I'll start the car and it won't tick while at idle. But as I drive away ill hear it for maybe about 2 mins only maybe in first gear until the car slightly warms up and then it's gone completely.

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.

Have a 2006 Sonata GLS with a 2.4 mileage has rolled over 207k .... I started hearing a slight ticking noise from the top of my engine and it has slowly gotten louder, now it can be heard inside the vehicle and more so when revving the engine...it also has 2 stored codes P0011 and P0456, I'm not too concerned with the evap code at the moment, I have decided to replace the oil control valve and clean or replace the lash adjusters...here is my problem, I have mechanic experience but only on Honda, all the youtube videos I have found for valve lash adjustment or replacement are for Mitsubishi and chevy engines, so I am not sure what the adjusters actually look like on this engine and if I can even do them without removing the timing chain.

It's a 2006 hyundai sonata LX.
Now Is it anything I should worry about? Car has 72000 on it. Always used synthetic Mobil 1 5w 30.
This is on a completely cold start up, 30 degrees outside. Only makes the noise until car warms up. Anything I can do to prevent this? Or is it not something to worry about? Should I just let the car warm up a little before I drive it?

I recently got my 09 ISF and had a few questions pertaining to some noises I'm hearing. Of course I'm hearing the ticking from the motor but until it causes any issues I can live with it.. My real questions deal with
A: When I go over a bump such as a pot hole cover or something that makes my suspension articulate quickly at low speed, I hear a rattling noise from what seems like the suspension / hub. If it makes any difference in on 2012 shocks and soft springs. (my extended warranty is kicking in soon so I hope that it doesn't play a roll in it as I'm sure they will be quick to deny it)
B: When I am coming to a stop or slowing down and the car shifts into first on its own (I think only in manual mode) there is a clunk / slight jerk sometimes... It may be coming from the rear end? Is it some type of locking or unlocking that's going on?

I have a 2002 VW Beetle 1.8L Turbo with over 120k miles. Recently it started idly roughly on occasion and had a slight rattling noise but only when stopped. When it was driving, it felt fine. This went on for about a week and then one day about a week ago it started for about 10 seconds and then stalled. Since then it will turn over, but not start. We've checked the starter, fuel pump, fuel pump relay and ignition coils and have replaced the crankshaft sensor (which was what I found on VW sites as saying it often solved problems like mine). The battery is new. Part of what I saw when researching was in addition to what is currently happening other owners had a long term issue with the car bogging down once in awhile at high speeds (50 mph+) for a few seconds and then picking back up again. My car did this as well and that's why I thought the crankshaft sensor may be the issue.

So, I have heard a little bit about the oil pump bolt issue. However, I am still confused. Was this issue fixed for the 2008 model and what are the symptoms? I changed out my valve cover last night due to a PCV valve failure. The car is running great except there is a slight rattling sound coming from the drivers side of the engine at idle. I know I left nothing around the car that could have gotten in the motor when the valve cover was off. This issue was not happening before changing the valve cover. What could be causing this noise, or is it typical for this motor?

I bought my sonata with about 48,XXX miles about 2 months ago, and now it has 52,500 (im a student - dont drive much). Anyways, whenever i start my car up and drive down the road, when the car shifts in to third, i hear a slight knock. almost like a little gong - metal on metal.
Once it does it the first time, it doesnt do it anymore. Im guessing temperature could have a factor?

My 2009 Sonata, 2. 4 L engine, base model with automatic transmission started up and ran OK, but 20 minutes later when I parked the car and shifted towards Park the gears grinded in neutral, stopped grinding in Reverse, and then grinded again when I made it to Park, and I quickly turned off the engine.
When I restarted, it grinded in Park, OK past Reverse, Grinded in Neutral, and then OK in Drive. How serious this is, or if there is anything I can check out on my own?

I have a 2003 Camry 4 cylinder with ~143K. When I start the engine I can hear a slight rattling noise. When I rev the engine the noise seems to go away (or it is just masked). I noticed the noise after the check engine light came on twice and I had it checked by an exhaust shop. The code was for an O2 sensor, but the exhaust shop said everything looked fine to them. This was about 7K ago. I jacked the car up a few weeks ago to check the exhaust for anything obvious, but couldn't find anything loose to explain the rattle.
I hit the exhaust pipe with my fist and heard a rattle a few times, maybe from the catalytic converter, but I am not certain. Everything runs/operates fine, smooth acceleration, fuel economy is unchanged, engine temperature is unchanged, but the noise persists. I don't know if it is just normal due to age and nothing to really worry about, or if it is the first sign of trouble. I have also noticed that I am using about 1/2 quart of oil between changes, but I'm fairly certain that started before this noise.

2011 accent gs. We purchased the car brand new and it currently has roughly 32k miles on it. About a month ago the car started to misfire at an idle (in park and in gear stopped at a light, etc.). At this time, I purchased a new air filter, and a new set of autolite platinum plugs. Roughly 3 weeks later it started misfiring again. After a few internet searches it seemed as though some people don't like autolite platinum plugs. At this point I purchased a fresh set of NGK iridium ix plugs and figured that'd be the end of it. I test drove the car for almost an hour myself (the same night I repaired it) with no issue. On my wife's commute the very next morning it acted up again.
We took it to the dealer this morning, and I honestly don't believe what they're telling me. They are insisting the problem is with spark plugs. They say that the manufacturer recommends copper plugs only, and that would be step 1 of their diagnosis/repair which they want $130 for. At this point I declined their service, and they'll let me put copper plugs back in. They said that if it continues to act up to bring it back in after that. Ah yes, and during this whole time there has never been a check engine light.

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.

So I always have the radio on so I rarely hear subtle noise like this, but lately I have tried to track down this noise I have been hearing.
Every time I back out of my garage, I would obviously have it from Park to Reverse...when I put it in D from R....there is clunking noise right after the first gear...
It goes first gear, than this clanking noise then 2nd gear....It almost sounds like a motor mount? I hope its something not too bad as a mount.
It only happens when engine is cold and it seems to only happen that one time I go from 1 to 2 right after R..
It's sound like a grinding metal but real quick...like something crushing.
I have done ATF flush at 30, 60, and 90; the 90k was done just about two months ago.

My 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?

My sister has a 2006 sonata V6 3.3, she got in 2007 with I think 20,000 miles on it, it has 180k. now. For the first few years she took it to the dealer for all the maintenance and oil changes. She has kept up with the oil changes and I think all the recalls were done.
There has been so slight noise at start up, but nothing I thought was too unusual for these kind of motors.
Yesterday she had an emergency with one of the kids, her faithful sonata fires up with an incredible amount of upper end noise, and it looked like it was burning oil. The engine was turned off immediately.
Her husband tried to start the car about a half hour later, he said it was hard to start, ran rough for moment, he revved it for a bit and it smoothed out running normally. No codes and no CEL. Oil level was good. Oil filter is a fram I think.
I started it a few hours later there was some lifter noise that quickly went away after a rev. Other than that it sounded normal and drove normally, normal exhaust from what we can tell.
There were no codes. and so far it has not done it again. But she is worried the engine is about to fail and she can't trust it with transporting her kids.
Was a timing issue? stuck valves? oil pressure? Oil Pressure to the cvvt (OCT?) maybe? They can't afford a new car right now, is this something easy to fix or is it a warning the motor is about done?

I have a 2006 Hyundia Sonata. I idles really bad like you pulled 5 of the six plug wires off when you put it in gear. Once you start moving a couple miles an hour it is fine. It is also perfect in park or neutral, not a hint of a problem. Put it in drive or reverse and it almost stalls.
