Elantra MD (2010-15) :: Rattle On Cold Start Up
Aug 10, 2015
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.

I 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?

Mine is just like this other owner's Elantra. Stealership say's "it normal". Surprise, surprise!
When I asked him how come my car wasn't doing it 50 miles ago and the 2013 loaner doesn't do it, his answer was "it's warrantied to 100k". I call BS. It's the timing chain tensioner or the the guides or both.
I say Hyundai knows about this and does not want to pay for warranty work because it's a costly job labor wise. Just like the Sonata's tensioner problems of the past.

This just started yesterday on cold start and happened again this morning and this evening always after sitting for hours. I would call it a chatter sound, very distinct and only on the first start. Never heard it before. Have 97K on car, will be changing the plugs soon. Once it is warm the sound is not there on starts. It is only when starting, sounds fine once running. What would only be noisy when cold like this? Timing chain? Valves? I'm going to let others with a better sense of engines than me (my son and his friend who are mechanics) listen to it and see what they think. But it needs to be cold. Never heard such a sound on my Hondas which makes me think it may be the chain. Funny how it just came out of no where.

When I leave the car in the parking space for a couple of days (in cold weather) and then start driving it, I notice that when I brake I hear noises (like thud.. thud...). Eventually as the engine warms up the noise goes away. I can never reproduce this at the dealer as I have to drive half an hour to the dealer and by that time the noise goes away. Should I be concerned?

Someone with a similar problem said it was a timing chain cover issue and someone else a cam shaft issue. It's a 2012 elantra limited 1.8L with 55000km the short block was replaced around 45000km.

There's a thread similar to this on the front page, but I wouldn't exactly describe my issue as a "rattle".
I've got a good video of the sound it's making here : [URL] .....
It's definitely much louder with the hood up--doesn't seem quite as drastic when sitting in the driver's seat.
I've come across the thread here on the engine rattle/knock fix, but I'm not sure if this is the same thing. Would this be considered a knock?
It's a 2011 Elantra with about 82,000 miles on the odometer. It has an extended warranty on it, in addition to the 100,000 mile powertrain warranty on it, so it's at the dealership this morning.

When starting the car and ONLY when it's a cold start, like sitting overnight, it makes this weird "groaning" or "whining" noise. I took a video of it because if I drive it to the dealer, then start the car there, it's not going to do it as it only happens after a long period of being off. Listen really closely after the car starts and right before the radio comes on, you will hear a faint groaning noise. It's louder in person, but this is the best I could do.

Wife has a 2011 Elantra 1.8L... 5 years old and only has 24,000 kms on it.
Barely uses it, mostly for short trips, keeps it parked outside in the elements.
I've noticed the fuel mileage kinda sucks and has a rough cold start and performance lags while driving.
is it worth replacing the spark plugs? Always seems to fix these kind issues with my past cars.
Even with the low kms I assume they might need replacing since its 5 years old?

I am the proud owner of a 2011 Hyundai Elantra GLS. After I bought this car (used), I have been having an issue with the exhaust. When you first start up the car, it idles and sounds great! But then as you put it in drive, well, that is when, what sounds to me like exhaust, rattle starts. you only hear it when you are on the gas or have a load on the engine (like A/C) at idle. It sounds like it is coming from the sound the left side of the engine (if looking at the engine from under the hood). Is there a way to fix it without taking it to the dealership?

Experienced an occasional (not always) rattle in the passenger rear area of the 2012 Elantra GLS. I have a video on YouTube of this specific rattle that I will post eventually, it says i have to wait a few days until I can post links on here.

I have a rattle in the dash up in the middle of the dash kind of in between the two sides of the car and between the window and front so basically right in the middle of the dash, if I slap it with my hand I can make the same sort of rattle so something is loose, bad thing is I dropped by dealership and it didn't do it when I was in the car driving with the service guy but I slapped on the dash and you could here a something loose sound rattle same kind I hear when driving. He said that is normal for things to make noise in there when you tap the dash. About a week ago I had the dirty sock smell coming from my vents so I took out the Cabin Filter and sprayed Lysol in the intake the put a new filter in. This is about the same time the rattle started. I wonder if the Lysol might have made something come loose in the vent system.

Experience with rattling coming from the rear/trunk area. My 2013 1500km new limited with Nav have developed a very bad rattle coming from the back.
I have tried removing the rear deck and no luck, There are now nothing in the trunk except for my spare tire kit. the rattle gets louder when I fold down the rear seat. The rattle seems worse and more frequent when the car is between 10 to 60 km/s...

Currently have 85k miles. About 20k miles ago I noticed when I have the driver window down I would hear a rattle coming from under the car when accelerating. Doesn't happen every time but does quite often. Usually goes away almost immediately. I'm not having any other issues and with my warranty out I'm not anxious for a drip to the dealer.

just about a week ago, i've noticed this weird rattle coming from the front end, sounds metallic (maybe something is loose) but it only happens when I accelerate from 0-80km/h, but the sound isn't there if I slowly accelerate. Nothing seems to be wrong with how it runs, its just the sound that sounds horrible, like nails on a chalkboard.
Also, I've noticed the engine ticks really loud when it gets started. However, the sound goes away after a minute of idling.
There is about 19,000 kms on it and I got it in January .. I travel a lot maybe a little too much.. I want to take it in to the dealership, but I'm pretty far from it and would like to know what it could be before I take it anywhere to get fixed.

So I've noticed this alarming engine rattle when I first start car as if there is no oil? It only lasts a few seconds! Was it diagnosed with Hyundai? Maybe a quirk of the motor, but seems like over time would cause excessive wear on engine?

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?

I had a 12" sub installed in my trunk & was getting a horrendous rattle from the rear deck area. My first instinct was to put Dynamat everywhere but after some googling i ended up filling the underside of the rear deck area with trashbags!! I pushed 5 of them through the opening where you access the 3rd brake light & it now it sounds perfect. I uploaded a video to youtube with a sound test.....

Light rattle/clunk in the steering column when going over bumps or sawing the wheel back and forth?
Lately I'm getting the sound inside the car. It feels like a loose bushing or something.

Suspension noise I am getting from my 2011 MD.
This noise occurs only over small shock type bumps IE, train tracks that are not smooth, those reflectors in the road, and the metal plates over construction projects. Any bump that forces the suspension over a small vertical or near vertical drop or rise of about one inch.
In my driveway I have a storm grate about an inch lower than the surrounding pavement and it rattles over this every day. Now the fun part.
The noise is ONLY when I hit such a bump with the right side of the car. The left side rolls over the same bumps smoothly and quietly.
This noise is also only present over the small type bumps discussed earlier. My dealer has a rough road that they use to test suspension noises and the car rolls down it silently. The problem also doesn't manifest itself over speed bumps.
The noise is still present while applying the brakes on which makes me doubt its a caliper float issue.
The strut brace and lower control arm/bushings on the right side have been replaced by the dealer under warranty but they can not seem to get to the root of this problem as both these replacements have had no effect.
From inside the car it is very difficult to pinpoint where the noise is coming from but it almost seems like the center of from suspension.
