This has to do with a rattle on cold startup from a gear connected with the VVT system. I have a 2010 camry that may be affected by this. It just past 60K miles so they probably will not cover it under warranty. Does the rattle get worse over time, or will it have an engine failure if it does not get fixed?
View 4 RepliesJust bought a used 04 XLE Camry for daughter--60K miles. 4 cylinder engine. Engine sounded great when test drove. She has had it for 2 weeks, the engine now rattles badly upon first cold start of the day. Clears up almost immediately (maybe 3-4 seconds). Shut down and restart-no problem--only when cold (or has been sitting for more than a couple of hrs.) I'm thinking it is the valve lifters out of oil, but don't know. And what was the repair?(engine oil was just changed(Synth blend--5W-30Wt.))
View 2 RepliesI left my car over night so that the dealer could hear my valve rattle when it was cold. Typically it rattles for about 4 miles and then never again until the next cold start. He called me today and said that he heard exactly what I reported and it was not normal. Then the diagnosis .... BAD ALTERNATOR!
I'm 52 years old, I have built cars from the frame up, I have changed and rebuilt many an alternator over the years, I have never heard one do this! If this is correct, and I must say that he has never done me wrong, I was real close to being stranded along the road!
I bought a 2005 Camry about 3 months ago. It has the 2.4l 4 cyl with about 139k miles. The car seems to run perfect, but it has a rattle noise right at start up on cold mornings. It only lasts for the initial 1/2 second start up, then it's gone. I'm thinking it's probably just a heat shield rattle or something, I just did a full synthetic high mileage oil change on it and that didn't work, so that just makes me lean more towards heat shield.
View 14 RepliesRecently bought 2002 Camry 2.4 .... Engine has a cold start rattle in the top passenger side. The noise stops after the engine heats up in about 10 minutes. I've changed the intake manifold.... Did not work. Looking for the OCV VALVE FILTER but cannot find it ....
View 2 RepliesI just bought 2011 Camry 2.5 6auto with 57k miles on it. The car make a rattle noise for a second or so on a cold start when sets overnight. I took it to the dealer yesterday and they replaced the timing gear assembly under warranty. This morning when I started the car in the morning it made the same rattle noise. I am going to take it back to the dealer next week.
My question is has any one had this rattle noise? if so, did the noise go away after the dealer replaced the cam gear? Also, Do you think this rattle will affect the engine in the long term?
I have a 06 camry as is said in the title, it has 120k miles, 20k of those are mine which i have treated it well in terms of fluids, changing oil at 2k and i changed my tranny fluid 10k ago along with the coolant. On a cold start (Its 5 degrees out for the high) it stays running but when put into drive it dies. My only idea is the transmission, because the reason i changed the tranny fluid is cause my transmission wouldn't shift into higher gears for a large bit of time i.e., getting stuck in third a lot.
View 3 RepliesMy camry has been great up until the last week. The weather has gotten extremely cold here and when I start driving in the morning or from any cold starts the transmission doesn't shift out of second gear. After I drive it a mile or so and slow almost to a stop it will shift normally until I park it.
It has 125000 miles on it and I hope this isn't a serious problem because it is a great car and has been well taken care of. Looks brand new on the inside and out and I've never had any problems until now.
I have the eip street series catback- that is it for exhaust mods.
Every time (when car is cold) I start out in 1st, just after I release the clutch (1100 rpms or so) I hear a slight metal rattling noise for a second or two. It sounds as if it is coming from near the cats. And the noise disappears after the car warms up.
What it could be? Is there a heat shield above the cats that might rattle?
My sister says that her navigation has been going out. She brought the car to the dealership and they said her entire nav system needs to be replaced. They can give her a refurbished unit for $800 + labor. The symptoms are as follows:
The screen will turn black but she can still hear the voices. The screen will come back on its own. She also gets an error message "external system not connected". She says that this could happen at any time, not just when the navigation system is being used. Also when this does happen it is as if the whole system crashes because she cannot control the AC heat and the radio goes out.
In my research i would say this was a nav ECU problem but I want to double check and so I am posting. I would like to know if the ECU from other model years can be used (assuming you carry over the same DVD version).
The rattle only lasts for a second or two. Only warning light recently was airbag control module, addressed by Dealer. Also noticed recently, while doing some "spirited" driving, there was a deep-bass thump sound at the end of each gear change.
I've done forum searches for start-up rattle and found issues with timing chain/belt, in relation to the tensioner bolt, mentioned in reference to an earlier design(?). I was unable to find anything related to the B7/NMS.
No idea if it's a V6 issue, DSG issue or general VW issue. NMS V6? NMS DSG?
CD was working fine the last time I tried it but just recently when I try and use it I get an "external system not connected" message. I haven't done anything to the unit and no recent repairs.
View 5 RepliesThere was a TSB for 2AR engine, Engine Knock/Rattle Noise at Cold Startup. My question is for those I4 camry owner, do you have these rattle sound when you start your vehicle at cold? I am not sure if mines have the same issue, but pretty sure is I can't find any differences between mine and this clip:
You Tube
So should I take it to the dealer? Or it's normal?

I have had a rattle that lasts 2 seconds on my 2012 Elantra for the since about 2 oil changes ago. The car has 152,000 miles on it and I've changed the oil regularly per the maintenance schedule, although not always with a Hyundai filter.
I'm strongly suspecting that this is the timing chain tensioner, but I could be wrong. Other than this, the car runs fine. I tried having the oil changed by the Hyundai dealer with the OEM oil filter and the problem appears to be a little worse. It first started to appear on cold start up after the car sat for >8 hrs or so. Now, it appears on cold start up >2 hrs. I noticed that the dealer put 5W20 in it.
I'm wondering if lower viscosity oil makes the problem worse during hot weather. It seems when the weather is colder it takes longer for it to appear. I'm wondering what my options are here. I really don't know how much $$ it is to go after the tensioner and how critical it is - the dealer said they do replace them and that doesn't always fix the problem though I'm not sure what he meant. I have read a few other posts about tensioners here, but I'm also wondering if this is an issue with the new engine.
So I am hearing a weird noise when I start up my Tig after it's been sitting at least overnight. I'm not sure when it started because if the windows are up when I start I can't hear it inside, so for all I know it's been happening since before the warm weather arrived. But anyway... It's a brief rattle, kind of high and plastic-y, like maybe a half-second long or less, when I first start up. If I turn it off and then start it again, no rattle. Don't hear it again until the Tig has sat for a while.
No CELs or anything or other signs of trouble. It's a 2014 with 24k miles, bought CPO at 19k.
I have a 2011 camry le, just got its 10,000 service the other day. When I am stopped with my foot on the brake and the vehicle in drive gear, I can hear a rattle coming from the front. But when i let go of break and accelerate it stops rattling. I told the dealer at the service but they told me they could no duplicate it.
View 12 RepliesSo my wifes 07 93k miles started to make a strange knock rattle noise. It sounds like the knock some on here have when the water pump was going out. It only happens when the car is on, in gear ( drive or reverse) brake pressed And AC ON. The engine begins to vibrate under the load and the rattle begins. Sounds like you its coming from behind the alternator under the valve cover. Once I place it park.... or turn the AC off it goes away. It idles fine. Quiet And Smooth. But once I place it year it comes back!!
View 1 RepliesI have a 2013 Azera w/technology package, it has 20,500 miles. I absolutely love the car, have had no issues with it. However, every time the car is started with a cold engine, either from sitting overnight, or sitting an hour when it's very cold outside (20's or 30'sF), there is a loud rattle like something is very loose or I've described it like it sounds like someone threw a bag of bolts in the engine for about 3-4 seconds. Then it runs like a normal engine. I've had it in the shop twice, the 2nd time they replaced the fuel rail injector assembly and all the injectors due to such a heavy carbon buildup in the cylinders. It still rattles horribly. It's an embarrassment to start, it sounds horrible and doesn't sound like the normal startup noise. This concerns me of the longevity of the engine. I have video of the start up noise even.
View 7 RepliesTwo months ago I bought a used 2006 Sonata v6 with 54,000 miles. After a few hundred miles I began to hear a rattle on cold start that lasts approx 5 secs. I did my research and saw the TSB concerning the timing chain tensioners. The TSB instructs the dealer to turn the engine off after reaching operating temp then restart after 10 minutes. If there was no noise after the ten minute start then the car is operating normally. My car does not rattle after the 10 minute start up. I just can't see this as a normal characteristic. What could be causing this noise?
View 1 RepliesI have a Hyundai Elantra Limited 2012. A few months ago the Short Block was replaced because the engine was noisy. Now it started to do that noise, if I remember it's a little bit similar : Youtube video: [URL] .... Or search youtube for: Hyundai elantra 2012 engine rattle noise
It rattled very loud for 1 or 2 seconds on a cold start the other day too. Noise appears to be coming from the engine. It does it pretty much all the time, at idling, when I accelerate it accelerates too and when I slow down it kinds of do too slowly. Need another new short block or is it something else like the timing chain or a bearing?
I have a 1997 explorer sport 4x4 4.0 sohc It has a real tuff time with cold starts sputters won't hold and idle sits at about 500 rpm once its warm its not as bad still has a low idle.
Also i have a constant engine rattle thinking left front cam tension-er
Also throwing and check engine light odb scan tool shows o2 sensor position two is bad
I was thinking intake gaskets and new tension-er is a good place to start.
