Elantra MD (2010-15) :: Chatter Sound On Cold Start
Dec 5, 2013
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.

So my 2014 Elantra makes a tapping/ticking sound on cold starts which stays audible after the oil gets up to temp for at least until about 10 minutes of driving. I've heard this noise since I bought the car and of course kept searching all over the forums but everyone seems to have a different opinion as to what causes it and if it's normal or not. I finally decided to drop my car off at the dealer overnight so they could start in the morning and diagnose it. They listened, ran some tests on the engine and said everything was fine, nothing was damaged and that the sound is from the second fuel pump that is located over the engine.
They tested my fuel and said it's making the sound because I'm using a heavy fuel quality, then the tech told me I should run a fuel cleaner every other time I fill the car up. This seems excessive to me? I only fill my car up with Shell gas and avoid discount places which the tech agreed that Shell gas should be fine. I only have 22k miles on the car do I really need to be running cleaners every other tank of gas? Also wondering if using non ethanol gas would fix this problem. I did run 1 tank of non-ethanol but didn't notice a difference and since non-ethanol costs more than premium I went back to regular. I will try a fuel cleaner though?

I have a 2012 limited (non tech pkg) and I want to see if my speakers are the only ones that have a buzzing to them during cold mornings? Once it warms up, the speakers tend to be better. I have the power bass on low and I usually listen to AM radio in the morning. Kind of hard to explain but there is a buzzing rattle noise when the sound reaches a high point. It isn't a constant noise but rather dependent on the sound.

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.

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.

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.

I have been driving 2013 model for five months. I noticed that whenever any front wheel rolls over cat-eye on the road and any sudden small bump then it generates noticeable clicking sound. I went to the dealer and they said it is normal and comes with all such cars.

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've had 2 Elantra 2012 models 1 a gls the second a limited. As far as transmission issues both Elantra's from a cold start after allowing RPM's to idle down before taking off they both have started shifting hard going from 1st to second gear 1st car was around 8-9 k miles now 2nd started at 3 k miles. Since owning 2 cars same make same year same transmission and many times to dealer 1st car ended with Transmission replaced 2nd has now started doing the same thing they reset adaptive and next day did it again its now back at dealer waiting for them to diagnose again.

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?

I have a 2012 Hyundai Elantra and I have had it for almost a year. Its been snowing here in Tennessee. I went to start my car and wont start. All the lights come on, radio, etc.I have tried jumping the car and wont work, even tried changing out battery. Not sure if theres any known issues going on or if it has to do with it being cold.

Our 2012 elantra gls with 112k miles on it decided to freak out yesterday.
Car wont turn over at all. there is also a clicking sound coming from the interior fuse block. I popped the hood and smelled sulfur. I put the volt meter to the battery and it shows 12.8 ish. I checked all the fuses and didn't find any blown. I also pulled the starter relay and tested it and it checked out.
Trying to turn the car over some times the dash light will flicker and the wipers will turn on by themselves. I also had a clicking sound coming from the fuse block under the hood. Interior lights come on but are dim and the parking light flicker a bit and fade. I downloaded the manual but am not sure what to look for at this point.

I've had my 2010 Prius for about 3.5 years now and this is the 3rd maybe 4th time happening. This morning I started the car and the car started to vibrate/rattle from the engine bay. It almost sounded like the wheel of fortune being spun but louder.

I just recently swapped out my Automatic Transmission in my 91 MR2. The person i received it from had the system completely drained, including the torque converter. I found this out kinda hard the way, knowing that the pan was empty, but not expecting the torque converter to be empty as well. After filling up the system, i thought i may have overfilled it, because the fluid level was reading above the hot mark on the dipstick. So i drained the fluid and replaced the transmission filter. I put in 3 quarts of fluid and added the 4th quart of fluid over time, mainly letting the car run and warm up to operating temp and then adding fluid and letting it settle.
I kept doing this until i got to the full mark on hot. So this is where I am at now... On a cold start, the transmission will chatter in all gears, from park to low. Give it about minute or so to start warming up the chattering slowly goes away. When its at operating temperature, there is no chattering at all in any of the gears, and it presumes to be normal and fine. It takes about 5 minutes to fully warm up to operating temperature. Should i worry about the chatter at the beginning while its warming up? i have to drive the car because I want to be sure that the transmission is okay. I have thought about adding an additive, but all that i have read is just bad results, and failed transmissions.

My 97 F150 4.6 4x2. I have a semi-rough front end "chatter" when the brakes are first applied after vehicle has been sitting overnight. It feels like it comes from the front disk brakes, I assumed it was a warped rotor or loose wheel bearing so I replaced the front rotors (old were to thin to turn), new wheel bearings and pads. Still had the issue, so I then assumed it was a bad caliper... replaced both those, and all related hardware. Still have the issue!
I can not reproduce the event until the vehicle is in the cold state and it will only do it once or twice, so I am finding it difficult to diagnose. Tired of blindly attacking this issue by changing what I thought was obvious. F150, 130K miles, 4.6l, automatic, 4x2, rear drums, front disk

So it's finally been nice this week, only problem was it was Humid as it poured for more than 24 hrs the day before. I tried using my Ac but all it was doing was blowing warm air. I figured it was the car being hot since it it black and it was sunny & I did have the car running. I tried using the Ac yesterday and it was blowing slightly colder air but still warm. I don't know what the problem is and so I went to my moms elantra to compare since we have the exact car just different colors and her car was blowing air as if it was straight from the arctic.

So I've noticed the past few days that the air coming out of the air conditioner isn't as cold as last summer. The car is only a year and a half old (2013 Elantra purchased Feb '13), so this isn't a problem I was looking to have so soon.
I wouldn't call it warm air, but it's not cold. Temp remains the same if I am driving or idling.
Luckily isn't hasn't been too hot down here in SoCal lately (70s-low 80s) but I know it will probably be warming up into the upper 80s and 90s soon. I'm guessing I am taking it in next time I go to the dealership for an oil change.

When I start my car I hear this very loud noise. I think it is coming from the exhaust but not sure. This only happens when the car is cold(not weather) and after a few minutes the noise is gone. I have aftermarket lowering springs on the car, do you think that caused the problem?(I'm thinking no)...
