Sonata NF (2006-10) :: 2.4 Engine Loud Knocking Noise When It Is Cold
My 2009 Sonata 2.4l Sonata has been making a loud knocking noise when it is cold, but it will fade to almost nothing after it warms up. I tried to make a sound clip of the noise, but it was so distorted that I could not even make out the noise on the video.
For some strange reason the noise matches the skipping problem I have been complaining about since the beginning. Yea it's still there. It sounds like it is in the valve system, not the lower end. It leads me to believe it's coming from the valve clearance/ camshaft area.
Mini - Cooper :: 2007 - Rattling Noise At Cold Startup
I bought a 2007 Mini Cooper, used, at a Ford dealership in August of 2010. For nearly two years I loved this car and didn't have to pay much in the way of maintenance. I bought the car at 55k miles, and now it has 92k. Over the past year, I have noticed a rattling noise at cold startup, and it was especially loud in the winter, and I also noticed that the car consumes oil. As the oil got lower, the rattling got worse, and whenever I topped off the oil the rattling stopped. I brought this up at the MINI dealership (where I get all my repairs on the car) during a routine oil change and they didn't take it seriously.
Well, Tuesday morning on my way to work, there was a sudden loss of power and the engine started missing bad. I was almost to where I work when the car just couldn't hold and idle and stalled. It wouldn't turn over after that and it sounded really "sick". I had the car towed to the dealer, where they told me the timing belt tensioner failed and it allowed the timing belt to jump "a great distance". Apparently, these are "interference" engines (a term I learned because of this incident) so the screwed up timing destroyed the engine. The dealer said it will cost 8,000 to completely replace the engine.

Lexus RX 2010-15 :: RX350 Engine Ticking / Knocking And Rattling On Cold Start
I just purchased a 2010 RX 350, has only 7k miles on it. Really, really nice car. I noticed for the first time yesterday the engine ticking/knocking/rattling/whatever you want to call it sound when starting up on a cold start. It definitely goes away after about 5-10 minutes of running.
Most people seem to accept this as "normal". They hear it, live with it, and they never have any problems. I am a new Lexus owner, so I have trouble digesting that such a luxury vehicle with so few miles would have a "normal" engine knocking sound at 7,000 miles.
A few people posted in other places that this is indeed an issue, and should not be happening. There is a a Toyota (Lexus) service bulletin that I didn't get the details on, it is LSB-0028-09. LEXUS: ENGINE TICKING NOISE AND/OR MIL ON P0014, P0015, P0024, P0025, P0017, OR P0018. ENGINE MECHANICAL. *PE
Looking for details on this service bulletin, and if it does indeed apply to the engine knocking sound.
- Premium gas
- High viscosity cold synthetic oil
- Dealer fixes issue
- Other fix?
Accent MC (2006-11) :: Knocking Noise Under The Car For A While
Ok, I've been hearing the strangest noise under my car for awhile now. It sounds for all the world like a drum stick is hanging by a rope, swinging back and forth, and hitting against something solid. It makes 3-4 loud taps and the vibration can be felt through the gas pedal/floorboard. It ONLY happens when pulling out while turning left or right and going over a rough entrance like a rain gutter that bounces the car pretty decent. So whatever it is doesn't start swinging under normal driving. For the life of me I can't imagine what could be that heavy to make noise like that and not be causing any other problems.

Fiance's 09 Corolla S just started having a rattle/knock noise this evening. car has 123k. It's clearly an engine internal sound. I believe it is coming from the cylinder head. She called me when it started making the noise, she shut it off and has only been ran enough to get it on and off the trailer.
Not sure if it's a broken valve spring or valve. or the timing chain guides? It threw a CEL light.
I ran the code on my scanner and it came back with: P0302 (Cylinder 2 Misfire)
Accent MC (2006-11) :: Rattling Noise At Around 5k RPMs
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....
Accent MC (2006-11) :: 2007 - Squealing Noise On Every Startup
I have a 2007 Hyundai Accent automatic. For the past few months, every time I start up my car it makes a horrible squealing sound. This sound also occurs when I'm backing out of my parking space and when I do turns. A few times when I'm doing turns the steering seems to lock up a bit and it gets really difficult to steer. I had numerous people check under the hood and they say that the pulley is seizing every time I turn the steering wheel left or right while it's making that squealing noise. I have had all three belts replaced and a new alternator installed last year. The belts have been checked numerous times since they been replaced. The power steering fluid has been a changed as well. Do I need a new steering pump? Or is the problem something else.

2009 Accent with a manual transmission
I am at about 65K miles so far. I changed my oil last night like I normally do. The car was on rhino ramps and as I started the car to back off the ramps, I noticed a very audible, "Tap tap tap" noise on start up, only. It goes away a second after I let off the key turn once the engine catches.
It did this when I backed it off the ramps and then when I shut the car off and waited a minute to check for it again on level ground and the same thing happened. Only two times and it has been quite as a mouse on start up since ever since. I want to say it is starter related as the noise sounds like a rapid tapping that slows and immediately stops as if the starting gear that engaged the flywheel is slowing to a stop once disengaged.
Sonata NF (2006-10) :: Grinding Noise At Cold Startup
Need to determine the noise before I took the vehicle in to be serviced. I don't know if I would necessarily describe this as grinding...to me it doesn't sound like metal on metal..but it's not normal.
Only happens on a cold startup, and even then it hasn't been 100% of the time...probably 80% of the time though.

Accent MC (2006-11) :: 2007 - Rattling When Engine Is Warm
I noticed that my car rattles (the engine) when is warm, if the engine is cold by the morning nothing happens, is just after the engine is warm (working condition) some people say gas quality but I use Premium and always the same station, the rattle is after switch gears, just for one or two seconds (sounds like click! click! click!)
Could be that the cylinder head is blown? Oil "Quaker State High Millage" was change 3000 kilometers ago, sparks plugs brand new NGK Iridium IX at the same time...

Accent MC (2006-11) :: Engine Valve Knocking On Slow Acceleration
I have yet another issue with my Hyundai Accent. It seems to me that I hear engine valve knocking. Here tech. details:
- This happens around 1100-2000 rpm.
- The car currently has 11500 KM.
- 3 oil changes so far - using Mobil 1 - 10W30.
- I put in regular gas.
- No mods, only bug guard.
I drive slow - slow acceleration and I noticed sometime ago that there was a knock coming from an engine at about 1400-1700 RPM, however now I can hear it anywhere from 1100 to 2000 rpm. I can hear it very well when I drive along curbs and walls since engine sound bounces off it. I have automatic gear box and therefore I don't know how to test it further ( on manual I would have put some load on the engine by switching into high gear and pressing gas - make engine struggle a bit ). It might be noise from injector but I don't know. Also I don't know if Accent 2010 has self-adjusting valves or not.
Sonata NF (2006-10) :: 2.4l Engine Tick At Cold Startup
I have a 2008 Hyundai Sonata 2.4l with ~235,000kms (~147,000 miles). It has been well maintained and has been a great car. It has been developing an engine tick noise at cold startup and it seems to be very gradually getting worse over time. This noise is most evident immediately after strarup and gradually dimishes over a period of about a minute and varies in terms of how noisy it is and how long it lasts. This nopise is never heard when the engine is warm. From what I have read online, this can be caused mainly by two things:
- use of an aftermarket oil filter
- timing chain tension insufficient
Late last week I changed the oil filter out from the Purolator Classic filter that I have been using for years to a genuine Hyundai oil filter. This did not make any noticeable change in the tick noise so I do not believe that this was a contributing factor.
Over the weekend I removed the valve cover and checked the timing chain tension. It was taught as it should be. I could push it down a bit between the camshafts but it would spring right back up. I also used a videoscope to look down inside the cam tunnel and found no evidence of the timing chain contacting any metal or the oil drip line for the lower timing chain sprocket. Everything appeared to be in order.
When I started the engine to confirm no leaks around the valve cover, I used a mechanic's stethoscope to check for the noise. I was unable to isolate it as the engine tick did not occur at that time. The cause of the tick noise continues to elude me, but I have ruled out the two common causes (oil filter and timing chain tension).
Dodge - Grandcaravan :: 2006 - Lifter Noise At Cold Startup?
Sometimes I'll walk my wife out to the garage in the morning when she is leaving for work. When she starts up her 2006 Dodge Grand Caravan FWD sto n go I hear a clicking noise for about 2 seconds. To me it sounds like the lifters prior to getting the oil delivery. I was wondering if that was going to eventually cause some engine damage and also if there is a problem with the oil pump or something like that. Is this a problem that I should check into or is this normal for this van. We hit a deer several months ago and the whole front end was wasted. I don't remember hearing this clicking sound when the van was newer.
View 10 RepliesSonata NF (2006-10) :: High Rpm Cold Start / Engine Is Knocking
Recently, our 2009 Sonata jumps to relatively high and not normal RPM when start cold (and I don't mean winter-cold; I mean first start in the morning). It jumps to around 2500 rpm for 3-4 seconds before it goes down to the normal 1200-1300 or so for a cold start.
Also, not sure if this is the normal Sonata engine sound, but when we push the accelerator it sounds like the engine is knocking, almost like a whistle of fuel flowing.
Sonata NF (2006-10) :: Noise On Cold Startup Coming From Serpentine Belt
I have a '06 sonata 3.3 v6. Let me first describe what was happening to the car before the noise started. When I first started the car and put the ac, the first time turning the steering wheel in either direction the steering wheel would tighten up and the battery indicator light would come on and the fasten seatbelt light would flash even though I had the belt fastened. It would only happen the first time I would make a turn and after that I could turn with no problem. So in recap, it would only happen on the first turn and only when the ac was on. Now when I start the car up there is a noise coming form the pulley/belt area. I wouldn't classify it as a squeaking noise more like a grinding. I've looked at the belt and it seems to be fine. After I start to drive the car the noise goes away. If I start the car again after a drive within about 2 hours the noise doesn't happen when I start it. What this noise could be? and also could the noise and the steering wheel tightening when the ac is on be connected?
View 1 RepliesAccent LC (2000-05) :: 2004 - Engine Rattling / Clicking Noise At Low RPM
Recently, my 04 accent (97,000 miles on engine and auto trans) has started to develop a rattling or Clanking noise coming from the engine at low RPM's. I flushed the engine and changed the oil and oil filter, thinking it could be due to oil clogging the HLA, But this was a no go. The engine is still making the noise, and I think it is starting to get worse.
The noise only happens when the car is idling at low RPM's. As soon as I rev the engine past 1000-1500 RPM's, the noise stops. The noise is worse when idling in gear, either reverse or drive, however as soon as you accelerate past 1000-1500 RPM, the noise goes away, until you decelerate to low RPM again. I'll try to take a video of it and post a link to it on here tomorrow.
Passat (B5) :: Valves Rattling When Startup On Cold Mornings / Idling Rough
Ok, I have owned my 02 Passat with the 30V 2.8L V6 since may. I got it with 115K and now its just under 129K I had the timing belt done at Jimmy's in Provo UT at 126K and up until then the engine ran great. Since the belt was replaced <along with the water pump and such> . The car has a tendency to feel like its idling rough, and when you start it up first thing on a cold morning it sounds like the valves are rattling. It does this for a brief second then goes away until the next time you start it in the cold morning. It wont do this if its warm outside, or after you start it previously that day. So far I have replaced the plugs with Bosch Platinum 2 prong plugs, and replaced the fuel pump. I replaced the fuel pump when it dead on me without warning about 2 months ago.
View 1 RepliesAccent RB (2012+) :: Knocking Metal Rattling Sound When Accelerate Up A Hill Or Slight Incline
Since about 5000 km, I have had a knocking metal rattling sound happening when I accelerate up a hill or a slight incline. It has happened a few times on flat road as well just more prevalent on the uphill battles. Now I assumed it was jus something loose that was rattling since I installed a cold air intake and had installed hid lights(I thought the ballast was banging on something). I tried and tried to find the rattle but I had no success. I read up on here about other people suffering the same problem and that running higher octane gas would solve it well I tried 89 and it was still there just not as much and I recently started using 91 and its gone haven't heard it at all.
