Engine noise

At 2500 miles I have started to hear a tapping or knocking noise in the engine. Dealer has heard it but does not think it to be serious. We compared the engine noise with another Azera and it was not there. Just wondering if anyone else has heard this noise. Keeps time with RPM, not real loud.

I will schedule a service visit if it is still there after I take a previously scheduled road trip next week.

I had the same problem and it went away when the oil was changed last week. The dealer said I needed to change the oil and filter every 3,000 miles or 3mo. to better protect the engine and that the ticking is caused by a hydraulic lifter sticking because the oil gets thicker over use and time and has difficulty reaching one or more of the lifters.

I also had them look at the computer and they added the feature of the drivers seat going all the way back when stopping and removing the key. They were not aware of this until I had them look at this forum to see the posted concerns about communications between Hyundai and the Dealers.

This morning I called 1-800-633-5151 which is the number in the maintence log for customers with questions to call. I first asked about oil change intervals and they confirmed I should follow the owners manual and maintence log (7,500 miles or 6 mo.) and to keep receipts so as to avoid any warranty issues. Nuff said! I then told the Hyundai Rep about communications between Hyundai and the dealers and how it was mention several times on this forum. She then suggested I write a letter to Hyundai to which I replied I had told her and expected her to relay these concerns and I would not write any letter to Hyundai. Wonder why Hyundai can't look at this for themselves to get a feel for customer concerns.

I also told the dealer that I would have paid for GPS and Sattelite Radio if it were available which it still is not on the 2007's.

I had my oil changed at 2500 when I took it in for the noise. I was going on a road trip and had it changed early. The noise was still there. It sounds lower in pitch than a lifter noise and seems to come from lower in the engine area. I will ask them to check it again at the next oil change. Yes, dealers and quick change places insist on pushing the 3000 mile interval, but the manuals recommend that only in "harsh conditions". Driving back and forth to work is not a harsh condition, it is a normal condition. I usually go with 6000 mile intervals.

Did your dealer charge you to re-program the seat?

My 2006 tiburon SE 2.7L did the same thing. made "tick tick tick tick tick" noise while idling. changed my oil to full synthetic and I haven't heard it since.

I have 4k miles on my 2006 Azera and hear the same noise in the garage when I start the car. I too was told to change the oil every 3k, however the toll free CSR said to follow the book since they govern the warranty, not the dealership. If you want to change the oil sooner you can.

There are alot of features that are available for this car but are not communicated to the dealer or the buyer. Have your dealer hook your car up to the HI-SCAN PRO Tool and have them go through the features. I wrote an email to an executive at Hyundai outlining the situation, and no response...

No engine noise yet but then again I only have 900 miles on the car. I do agree there are so many options on the Azera and I have the Ultimate package. Garage door opener I don't even have a automatic garage door. I still trying to figure out the radio. Everybody I talked to has a problem with a clunk in the front suspension. I have a clunk but it isn't very noticable but the way I understand it the problem can't be fixed only patched.

How about you guys do you hear a clunk in the suspension?

When do you hear the klunk?

Have not noticed it yet...

The clunk is heard a low speeds say around 20 or 30 MPH. Sounds like a hollow sound hard to discribe but it is noticable. Many Azera consumers have the problem. I noticed it when I drove the demo at the dealer but didn't pay too much attention to it because I was caught up in the rest of the car and the options. Then when I bought my new Azera I started to hear about a week after I had the car, only because I read it on one of the forum pages.

To me it really isn't a big deal but it should't be happening on a $30,000 car. The ride itself is great and of course the confort is flawless. The clunk is a problem and the dealers can't fix it. If you don't notice it now you will.

I have not heard the clunk on my Azera.

BTW, I recommend registering to the www.hmaservice.com website. It is a Hyundai site for service info. Has bulletins and fixes for some of the problems in their cars.

I have not, after 5,700 miles, experienced a 'klunk' or any other strange noises. I have, however, noticed that the ticking noise from the engine has returned. I called the Dealer and we agree it sounds like one of the lifters is the culprit and they asked me to bring it in for further review. I'll go in in the next couple of days and then post their findings and recommendations.

The dealer drained a pint of oil from the crankcase and put in a pint of additive (brand unknown, I didn't see it) and the whole thing took about 10 minutes. The ticking noise caused by the lifter is gone and when I asked about it coming back they said to call them so they can order parts to replace the lifter(s), install new gaskets, etc.

I think what I will do instead, if the noise returns, is to use a synthetic like Mobil 1 to see if it will provide adequate lubrication. I really don't want to have to go thru a partial teardown of the engine with only 5,800 miles on it.

If anything changes I'll post it.

Mine does like that also at first I thought that the use of synthetic oil is too thin for my engine but found out that the culprit was the damaged engine camshaft. It cost me a lot for such major repair.

It is really important to change your oil regularly as when it breaks down into sludge, it will result to a stuck lifter which consequently causes a tapping noise.

on the start up noise in the garage. when it sounds like a ratchet in the morning right after starting you need to check with your dealer for worn timing chain tensioners they had them in the first models ask to check the tsbs for the azera.otherwise make shure u use the right viscosety 5w-20/30 or synthetic since the new motors are needing the thin stuff to work right.

I now have 7,200 miles on the car and no stuck lifter like noise since they put the additive in it. I will insist on synthetic oil with a 5W-20W viscosity when it changed. I will also remember about having them check and relative TSB's if the noise returns.

I am headed to my Hyundai dealer first thing tomorrow morning as the clicking noise has returned and I want them to fix it for good. I noticed, over the Holidays, that I did not hear this noise until the engine got up to operating tempeature, and its louder when standing on the passenger side of the car. I am prepared to leave the car and pick it up when done and will post the findings so others will know the outcome.

My click returned after the dealer changed the oil last week.  Rogerf, please keep us posted on your situation.  I am going to see if the noise disappears after an upcoming road trip.

I called the Dealer this morning to get an update and was advised they had been backed up and had not yet looked at my problem. I told them to hold off, this is the 3rd day and I need the car tomorrow and Friday. They said we can agree on a fixed time later for them to have the car 3-5 days in case its necessary to 'dive' in to the engine. It seems they will have to pull the motor to fix internal things like a cam or lifters.

Had oil changed and asked dealer to listen to engin noise again.  They heard it and believe it to be from the timing belt tensioner problem.  Next week they are going to replace it.  Thankfully they will give me a loaner. I don't like the idea of my engine being pulled out, but the noise is spoiling an otherwise great driving experience.

I went back to the Dealer the 4th time a couple of weeks ago. (I am behind on posts due to catching the cold from HELL!)  They had the car for two days, changed the oil, and then called to say they could not duplicate the problem. They even drove it some 30 miles to make sure the engine was warmed up. This was after they heard it 'ticking' when I first pulled in.  I picked up the car, drove a couple of miles and filled the tank, and it was quiet. By the time I got home (32) miles it was ticking again.
 
I first called for the Sales Manager but he was on the phone. I then called the Service Department but ended up on their recorder. I left a message with them and put the phone near the engine so they could hear the noise. I never heard from them.
 
Last night I recieved a phone survey from Hyundai. I dissed them real bad about service and told them Toyota was building  new dealership which would open this Fall and it looks like I will have to go back to them since the Dealer has soured me on Hyundai!
 
I'll wait to see what happens but I won't volutarilly take the car back for repair. Its under warranty, I have my service receipts to show I am following the instructions in the manual, and I have 100,000 miles to drive without worry of cost to me.

Dealer has had my car for 5 days now. They called and said they may be finished on Tuesday, they said "it is a BIG job".  I really don't care how long it takes, I have their loaner Sonata. I just want the car back in one piece with no noise.
 

I went in to Ft Worth today to run some errands and decided to visit another Hyundai dealer which also happened to be somewhat larger and presumably more experienced than my dealer. The Service Writer told me they had seen this 'engine ticking' several times and in all cases it turned out to be the fuel injection system. They referrred to it as "pulsating" which happens when the injector squits a mixture of air and gas. It happens on a random basis, on different makes of Hyundai vehicles, causes no harm whatever, and I should not be concerned. (Its true I don't hear it inside the car). At this point I am not going to worry about it unless something chages.
 
I looked at the new Veracruz and I must say I was quite impressed. The Limited model will not be out for several months but it will come with a Navigation System, DVD Player, and XM Radio. Buyers will also have the option of NO MOONROOF. I did not take time to drive the vehicle but did sit in it. I will take a serious look when the 2008 Models come out. It was every bit as nice as the Lexus 350 and its larger than the Pilot or Highlander.

The noise in my Azera is/was not injector noise.  I can recognize the injector noise in addition to the abnormal one.

My dealer said it was due to the timing belt tensioner.  There is a service bulletin about early models, but it said the noise was not harmful and only on cold startup.  Anyway they said it would fix my noise but it would take three days to pull the engine and fix it.  I reluctantly agreed, partly because I kept bitching about it every service visit, and it did bother me, a lot.

TWO weeks later, after claiming they had to backorder an engine mount, the car was returned to me. I had it one day and found oil on my garage floor. Took it back today and they now say one of the valve cover gaskets was damaged in the repair process.  Now they will have it until "maybe Monday", because they have to order the gasket.  I don't know what company takes 3 days to get a part, you can overnight anything to anywhere now. I think they are afraid to tell me it takes that much time to fix it.

Thankfully I have a Sonata loaner, so I am not without a car.  But I have lost confidence in my dealers repair department. By the way, the Sonata is very nice to drive, and actually has a more precise steering feel than the Azera.  The Azera is a much smoother ride and of course much bigger all around.

The Azera has a 3.8 liter that has an internal timing chain. Unles you have the 2.7 V6, that has the timing belt, you have a chaint tensioner. If the dealer said it is a belt tensioner...no wonder they can't fix it since they are looking for a belt tensioner that is not there rather than a chain tensioner. Did they mean the serpentine belt tensioner? That's external and does not require engine removal. Seems like your dealer is using your car as an OJT project for their mechanics.

It is a timing chain tensioner. I used the wrong term.  I have seen the Service Bulletin for the Azera timing chain tensioner on the Hyundai service website, so I know it is a known problem.
 
As for the OJT, I can take pride that I am helping out the next customer !!!
 
 

Azera has been back in my possession for a week now.  Everything seems to be working.  I haven't heard "the" noise, yet.   I hope my dealer appreciates the $2000 they will get from the warranty work.
By the way.. I shamed them into programming my door locks to lock at 15MPH.  It was the least they could do after a 3 week repair job.
