Get a rattling sound when in park and when it warms up after a little drive it goes away, When a gear is engaged the noise goes away. Pretty sure its the dmf but whats causing it.
View 1 RepliesSo I'm approaching my first service interval and I'm wanting the dealer to check out a few minor issues I've been having with my GTI. Namely, a squeaky sunroof when it's cold out, slight vent fan rattle, and the occasional "fish bite" from the engine. I've already talked to the dealer and told them of the issues and they seemed reluctant to give me a loaner if the car takes longer than a day.
View 6 RepliesI 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?
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?
Just 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 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.
I 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!
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 drove my car downtown this morning. It was 7 degrees outside! - The windshield/dash rattle is no longer a rattle noise. It sounds like two Styrofoam boxes that are next to each other making a loud rubbing/creaking noise. I can hear it over the radio! I don't even have to go over a bump! Just turning in a curve in the road where the car leans slightly will produce this noise.
This problem is so un-Lexus like that I cannot believe it! - We are not talking new technology here folks! Cars have had Windshields and Dashes for over 80 years. Lexus had this problem solved when they released their first car! I have never owned a car that has done this. I am betting even a Yugo would not have this problem!
My car is going to the dealer on Monday to fix this problem. Luckily my dealer has said they have fixed this problem before and have never had it re-occur. We'll see about that! This is the only thing that is wrong with my GS350 in over a year of ownership. What I cannot believe is that Lexus knew about this problem in 2006 vehicles and it is still there in 2007! This is not rocket science! I will be very interested in hearing if this problem is truly corrected in the 2008 models!
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 RepliesI've noticed this of late. An irritating rattle from the driver's side door, but the key is that it only happens when the temps are cool. If the car is warm/hot due to being out in the sun, there is no rattle. This tells me it's something resolved when heat makes parts expand, but if I can stick something in that will stop the rattle altogether, I'd prefer to fix it.
View 7 RepliesOur 2007 RX350 with 91,000 miles started an annoying rattle at startup that lasts a couple seconds then goes away. The car drives fine and makes no unusual noise after the initial start. Its definitely not normal as it hasn't done it the last 91K miles we have driven the car.
View 3 RepliesCurrently working on a friends 2011 Prius with roughly ~340,000 miles (!!!!!) that was used as a taxi, until now, he bought it from the taxi company and converted it his own daily.
I did a regular oil change on his Prius, and decided to change the spark plugs as at the time there was some sort of occasional shaking/rattle at cold startups. The shaking was gone after changing the spark plugs. This was all done back in March. Yesterday, he was driving, and all of a sudden, the knocking came back, a check engine light, and white like cloud smoke appear. Check Engine lights were P0300, P0301, P0303 (misfire cylinder). I told him to bring it over, I took a look, and his invertor engine coolant was all the way down (he told me he filled it up to top just two weeks ago). I originally thought maybe it was the ignition coils (for shaking), but the white smoke didn't make sense. So I purposely filled the coolant above the full line, and took it out to drive for about half a mile, and just as I suspected when I opened the hood, the coolant level decreased, at least by an inch.
I did not see any oil leaks, and the oil levels were just fine. The car just seems to shake/rattle at startup and when accelerating at low speeds (roughly 8 - 15 MPH) and than goes away, and drives normally. It still does blow off that white/cloud smoke when accelerating hard on the engine though. As for the smell of the smoke, I can't really tell, it is definitely not sweet, but it kind of smells foul/bad.
At this point, I am pretty sure this engine is gone, and the gasket/seal is blown.
Just noticed a rattle above my head when temp drops below 60, only on certain rough, washboard surfaces. I am running 44/42 PSI, so I know what I am getting into. I have no intention to fix the rattle other than cranking up the radio. I know when cars age, they eventually develop more rattles. Question is, when left alone, do rattles do any long term harm? As in loosing something else and create a new rattle, or get worse.
View 2 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 RepliesStill considering the change from my '08 F250 to a newer F150 with the EcoBoost. I have been driving as many of them as I can to get a feel for them. My current question is this: if one exhibits the dreaded rattle at cold startup, does it always get worse with more time/miles? I found another one that I'm pretty happy with overall, but it does have the startup rattle for about a second at cold start, and only at cold start. Is it worth the gamble, or should I keep looking? It's got about 108k miles and is otherwise in fantastic condition...
View 8 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:

So should I take it to the dealer? Or it's normal?

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 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 posted a few weeks ago about the 2009 Corolla XE that I purchased from a Toyota dealer with 95,500 miles. Within days a buying the car it began to make a brief loud rattle on cold starts. People on this forum directed me to the VVT and they were right on. The car came with a 60 day warranty so they replaced the timing gear at no cost to me problem solved.
Now several weeks later, last night when I got out of the car with the engine running I heard a pretty loud noise that sounded like one valve very out of adjustment. This morning when I started the car the noise was no longer there but when I checked the oil it was a quart low. I have put about 1800 miles on the car since I bought it and the oil was changed at the dealer right before I bought it. I thought it being low on oil might be causing the noise. I took the car to the dealer and explained everything, the put a quart of oil in it and said to bring it back in about 1000 miles to check it out.
When I got back home the noise was there again so I guess being low on oil wasn't the cause. In terms of oil consumption the service rep said Toyota considers up to 1.1 quarts per 1200 miles to be normal oil consumption. This sounds like a lot to me.
And in terms of the noise that sounds like a loose valve I'm beginning to think it had something to do with the work they did to replace the timing gear. What would make this noise come and go? Doesn't seem to be any relationship to operating temp or how long the engine has been running.
So I guess I have two problems, potentially an oil consumption problem and a intermittent loud noise that I don't like the sound of. My power train warranty expires Nov 19.
And do the valves on 2009 are adjustable, the service rep said they were auto adjust?
