Elantra MD (2010-15) :: Rattle On Cold Start Up

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.

Elantra MD (2010-15) :: 2012 - 3 Small Backfires For About 2 Seconds After Engine Shut Off

This just started last night. 2012 e ltd goes "pfft" 3 times after shut off. Sounds like 3 small back fires about 2 seconds after I shut off engine. Very soft sound. The third one is not quite as loud as the first two, and if the door isn't open, you can't hear it. Seems to be coming from under the engine cover, near the throttle body.

Let me add the mileage has dropped from about 26.9 in town to 23.6.

Camry 2012+ :: 2AR FE Engine Knock / Rattle Noise At Cold Startup

There 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?

Sonata NF (2006-10) :: Rattle On Cold Start That Lasts For 5 Seconds

Two 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?

Elantra MD (2010-15) :: Tapping Noise On Cold Start

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.

Elantra MD (2010-15) :: Noise On Cold Start When Braking

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?

Elantra MD (2010-15) :: 2012 GLS Engine Will Turn Over But Won't Start

I just got into my 2012 GLS Elantra and tried firing it up, and the engine will turn over, but wont start. Power windows, radio, lights, everything works. Earlier in the day, I moved the car from the garage to the driveway and turned it off about 30 seconds after I turned it on..

I've read things from checking the sparks to the fuel pump..is it possible that it could be flooded? I am leaving it alone right now and I plan to try to fire it up in an hour or so with the accelerator fully pressed down in case this is the case, hopefully that does the trick..

Elantra MD (2010-15) :: 2013 - Groaning Or Whining Noise On Cold Start

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.

Elantra MD (2010-15) :: 2012 Dash Rattle When Driving

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.

Elantra MD (2010-15) :: 2012 - Power Steering Pump Making Whining Noise That Changed With Engine Speed

So I have a 2012 Elantra Limited. From what I understand the power steering is no hydraulics and is only electric assist. So I have a strange problem. I can remember in previous cars when a power steering pump was going bad it made a whining type noise that changed with engine speed. My Elantra is making the same type of noise. I'm trying to track this down. My car doesn't have any other symptoms aside from the noise. It's hard to really tell but it does appear to be coming from the belt side of the motor (passenger side).

Elantra MD (2010-15) :: Pulley Noise That Lasts For About 3 Seconds

I have a 2013 elantra with about 26,000 miles on it. I usually don't use it on weekends and on Monday's it makes a noise that lasts about 3 seconds. I believe the noise comes from a pulley that is not turning.

When this first happened, pulley had a couple of lines where paint peeled off and now the pulley has almost no black paint left. Took the car to dealer, explained how the noise only happens after not using the car for a couple of days, and they have not been able to repeat the problem, they indicate that they can't replace the pulley for this reason and that the wear on the pulley is normal.

What is causing the issue?

Elantra MD (2010-15) :: Alarming Engine Rattle On Startup As If There Is No Oil

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?

Elantra MD (2010-15) :: 2012 - Sound System Buzzing On Cold Mornings?

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.

Camry :: 2010 - Engine Lifter Ticking Noise On Cold Start Until Warm

I just punches a 2010 Camry 4 cylinder with 44,646 miles. Very clean. I've owned 2 camrys in the past a 97 and 2002 that both reached well over 200,00 miles without a hint of trouble. Well, when I start the 2010 when its cold like from overnight it sounds like the lifter are ticking?, it lasts until the engine is warm and then I don't hear it. It still has the 2 month 3000 mile warranty from the dealer. I just don't seem to remember our other Toyota sounding that way.

Elantra MD (2010-15) :: Rattle Noise Is Coming From The Center Of Suspension

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.

Elantra MD (2010-15) :: Road Noise - Rattle Sound On Doors?

I've noticed there's a bit more road noise in my Elantra in comparison to other competitor cars, and ever since I installed new speakers in the car with much more bass, the doors have been rattling quite a bit.

Sound deadening on the Elantra between the doors? I'm thinking of doing it but I'm not sure if there's enough space for foam or whatever would work best.
