Are you using quality oil filters?

 

Having it changed everytime at the dealer where I purchased. I have not looked at the filter to see what brand it is. I will check

 

sounds like your lifters are bleeding down and are pumped back up when you start it. Not typical in todays cars.

 

Mine does the same thing. The dealer told me that was "normal". Let me know what yours says.

Thanks!

 

Mine also does the "rattle". It sounds horrible, but goes away after about 1.5 seconds.

 

My 2013 Azera will do this after a few weeks of not bring started, I believe this is normal as the valve lifters leak oil out and then upon starting the engine they need to pump back up with oil. If the clatter persists then dealer should be notified.

 

Interesting - I'm a Cadenza owner and other Cadenza owners have been complaining of this (have not had this problem myself). See links to threads below. Would be curios to see if other 3.3 GDI owners have the same problem (I think this motor is in Santa Fe and Sorrento as well).

My 2012 does the same. Lasts for 5 seconds and then quiets down. People around wonder what's wrong with the car. Kind of takes away their good impression on the car. Pretty poor for a car at this level.

 

No problems with my 2012....take it in to the dealer and have it checked out.
Are you using a Hyundai OEM oil filter ???

 

I would blame the oil. Does it make the noise on new oil too?

 

My 2013 does not do that and no one should accept that a normal. THe guy who said his does it after sitting for a couple of weeks may be normal but not just sitting over night.

 

I'm wondering how you can even hear this from inside the car. I push the button and it barely seems like the engine started (so quiet).

 

Mine does this even after its most recent oil change. If I have the windows down in the garage and start the car it sounds like a thrashing machine. Even my wife says that sounds like it is about to blow up. I must say I owned a 2011 Sonata, a 2012 Sonata then upgraded to the Azera. 5 trips to the dealer for an air leak in the roof, latest trip was at the dealer for 2 weeks for a new roof seal. now this noise? Never had any problems with either Sonata both which had 60000+ miles when traded in. What gives? Did I get the lemon?

 

What kind of oil do you use and how often is it changed?

 

Really don't know. The dealer does the changes I am going to ask when I take it there to have this noise investigated. Same dealer that did both Sonatas, none of them ever had this issue. By the looks of the threads the Cadenzas also are doing the same thing. Has to be something with this engine.

 

This is good example of what the dealer gives you may not be the best.

Ask them if they are using genuine Hyundai Filters per their TSB about engine knocking.

 

Will do thanks for the tips

 

I have the same morning startup noise, talking with dealer this week.

 

Noisy engine at Start up

I have had the same problem for over two years (19000 miles), especially when starting in the morning in the garage. Have not been able to reproduce it for the Dealer where I have had the oil changed since purchase. It doesn't sound like "lifters" to me, its more of a rattling than knocking sound. Doesn't last long, especially when warm.

 

If you consider the location of the oil filter on the 3.3, you would think that more people might have this problem. I wonder if there is an anti-drain devise that isn't working on some cars. You would think that an "upside-down" oil filter like on the 3.3 & 3.8, would drain all it's oil in an hour or so.
You get a rattling sound like that when you change your oil, and the engine is without oil for three or four seconds, on start up, until pressure is built up.
This can't be good for an engine to have this happen every start-up.

 

2014 Azera - Zero issues with 3.3L mechanical engine noise though I do have a drive belt shudder/vibration noise when rpm's are coming down to idle - almost 3K miles on it now - never any engine noise issues on startup after sitting for a weekend.

 

I remember watching a YouTube video of an Azera oil change, and they mention that you had to be very careful when installing the two "O" rings on the filter body.
I wonder if a twisted "O" ring could cause the oil in the filter to drain back into the crankcase?

The guys doing oil changes, at the dealer, are often hurried.....Maybe they don't even install the small "O" ring.

I don't know if the engine in the new Azera has a timing chain or belt. But in our 2006 (and many had this problem), the start up "lifter noise" was the timing chain tensioner. We were told many times by the service department that this was normal--but it isn't.

The new Azera has a timing chain. As for the oise at startup, this happens on some cars. If it is only for a second or two. Some engines drain down more than others.

 

So did anyone who talked to their dealer get any new information on this?

 

When I first got my Azera I heard this also - and immediately thought "no oil!!!" - cause that's sure what it sounded like. I raised it as issue with the dealer and they told me it is normal with Hyundai's. First car I have ever heard where that is "acceptable". Still scares me every time I crank the engine.

My Accord and Continental both had timing chains and neither one ever made such a racket.

That's a load of BS.

 

Guys and gals I just had this experience fixed by me dealer. Not pretty for a car that only has 15000 mi on it!

Sorry I just ended up starting a new thread!

 

Perhaps the moderator can combine the two threads? The other one is here: http://www.hyundai-forums.com/hg-2012-azera/302226-valve-rattle-start-up.html

 

Is that something that falls under the ten year 100k PT warranty? Presume it is and in that case really not going to lose sleep over it for now.

 

Ok so I have been away for while.
They replaced the CAM chasers,a and the CAM shafts. Took a week.

Update still not fixed.

Took it back to the dealer. They had an engineer from Hyundai come out to look at it. He said it is the CAM phasers. My dealer told him they replaced all of them.

Now they are replacing the motor and taking my original motor back to Korea to tear it apart and see what is going on.
