Azera HG (2011-16) :: Valve Rattle At Start Up
Aug 22, 2014
Every time I start my 2013 Azera there is a rattling of the valves like there is no oil in the top end. I have heard other owners complaining about this so I asked my dealer when I went in for an oil change. The last three changes I have asked and he told me the same thing, there is nothing being reported. So I got my oil changed and went home. Parked the car for 6.5 ~ 7 hours and when I started it up the sound was louder than ever. I called the dealer back and told them. They asked me to leave it overnight so they could hear the noise for them selves. I dropped the car off that evening.
I got a call the first thing in the morning and they said that their tech did hear something and they were going to test it again in two hours and call me back. They called back and said they believed it was the CAM phasers. They gave me the car back while they ordered parts and rounded up a loaner. I dropped it off on Thursday.
Two weeks later (today) I picked the car up. Here is what they did. It turned out to be the CAM Phasers so when they got in there they also had to replace the CAM shafts (All 4) as well. I am sure there was more going on than what they told me, after all they had the car for two full weeks!

I have a 2013 Azera w/technology package, it has 20,500 miles. I absolutely love the car, have had no issues with it. However, every time the car is started with a cold engine, either from sitting overnight, or sitting an hour when it's very cold outside (20's or 30'sF), there is a loud rattle like something is very loose or I've described it like it sounds like someone threw a bag of bolts in the engine for about 3-4 seconds. Then it runs like a normal engine. I've had it in the shop twice, the 2nd time they replaced the fuel rail injector assembly and all the injectors due to such a heavy carbon buildup in the cylinders. It still rattles horribly. It's an embarrassment to start, it sounds horrible and doesn't sound like the normal startup noise. This concerns me of the longevity of the engine. I have video of the start up noise even.

Many months ago I had a rattle in my 13 Azera. Of course when I took it back to the dealer they heard it but when I left it was gone. I had a scheduled service to have it looked at but the rattle never came back.
The last two weeks it is back louder than before. I thought it might be coming from the passenger seat belt housing on the side of the door but now it sounds like it might be coming from the passage side rear door or maybe the sun roof. Hard to tell yet my girlfriend was in the car last night said it wasn't coming from the passenger side seat belt housing sounded more like the rear of the car.
So going to make an appointment to get it looked at next week. I hate rattles! I looked all over the car yesterday after had her cleaned up. My trunk is empty, so not sure what it could be.

I recently bought this CPO Azera that came with 100k mile powertrain warranty. I noticed startup rattle that occurs when the car has been sitting for 30mins and longer. It usually lasts 2 - 4 seconds.
I wanted to take it to the dealership but I want to make sure that I approach them the right way and won't be sent home with "this is normal behavior" as it happened in many cases when I was researching it. I suspect chain tensioner but I might be wrong.
2013 Azera Limited with 49k miles ....

I just purchased my 2012 Sonata GLS about 2 weeks ago and had 64,000 miles on it. Put a few hundred miles on it around town without issue and then head out on a road trip and put about 750 miles on it when I had the issue. I was going about 60 mph and went to pass a semi and when I stepped on it the car started lurching, crazy valve rattle, and seemed to lose a lot of power. Got back behind the semi and babied it until I found a place to pull over and check it out. It was 2 quarts low on oil so I topped it off and it sounded fine, running smooth and no ticking or anything. Drove it around a bit and everything seemed fine and eventually got back on the highway and running fine. Pulled over after 100 miles and another 1/2 quart low, topped off.
Another 100 miles and another 1/2 quart, but running great with no issues. 150 miles from home and it happens again when I try to pass with the rattling valves and loss of power and I have to limp it to a gas station and now hearing the valve rattle and chugging on just a slight incline and going 20 mph. Get it towed 150 miles back to the Honda dealer where i purchased it from (long story) and their tech drove it and said he thought it needed a new motor since he barely made it back to the shop. They send it over to my local Hyundai dealer, and all of the sudden it is running great again! I go and drive with the tech and hammering on the throttle and it's running like a champ. I left it for him to drive home and they put 98 miles on it without issue. I picked it up yesterday and they said to bring it back if it happens again, but totally stumped as what it could be. They did start the oil consumption test so I will update when that is done.

I have a 2014 Sonata with 22k miles. I love this car but lately I've noticed valve rattle under acceleration. Brought this up with service tech and he said I'm not driving the car on long enough trips to keep it cleaned off. When I researched the GDI very little info comes up for Hyundai mainly vw and BMW. I guess what I'm asking is is the only fix for the carbon build up removing the intake and cleaning the valves manually or is there another way.

I left my car over night so that the dealer could hear my valve rattle when it was cold. Typically it rattles for about 4 miles and then never again until the next cold start. He called me today and said that he heard exactly what I reported and it was not normal. Then the diagnosis .... BAD ALTERNATOR!
I'm 52 years old, I have built cars from the frame up, I have changed and rebuilt many an alternator over the years, I have never heard one do this! If this is correct, and I must say that he has never done me wrong, I was real close to being stranded along the road!

Is there a way to remove the prompt on the map display on engine start?

When my car sits for a few hours and it starts the engine is very noisy and rattily, for a second or so. One of my coworkers heard it the other day and made a comment. Oil is changed every 4000 miles, level is good. This is consistent and does it every time it sits for a while then starts.

Whenever I start or turn off the car and the steering column moves into its position at the time, it makes an odd noise. It's beginning to do it all the time. It's really hard to describe what it sounds like. Is this normal or could lead to another issue down the road?

3300 miles in, and my brake pedal is extremely hard/stiff when I attempt to start the car. I don't have issues getting it to turn on, but it literally moves maybe 1/4 inch at most. It just randomly started doing this.

My son-in-law came by tonight and showed me his ticket from his oil change at the dealer on his '08 Azera, 108k miles. Tech remarked that both valve cover gaskets AND the oil pan gasket were leaking. I've walked through his garage many times when my daughter has the car at work and I've never noticed any oil on the floor. Should have I seen any? I told dealer I would just drive it and monitor the oil level and any other signs of oil leakage. Since he bought the car with 101k miles and a fresh oil change ticket and never checked the level over the next 7k miles I don't think it's leaking bad.

Recently my 2006 Azera Limited with 3.8L V6 is making a valve tappet noise when cold - it goes away when the car is driven a few minutes. It now has 142K on it, is it just that the tappet has gotten 'dirty' and is sticking, or is this a sign of a much more serious problem? I am presuming the Azera has hydraulic tappets. There is no lack of engine performance or misfire at all. I have not yet changed its oil, the dealer I bought it from said they changed the oil when I bought it, just under 3000 miles ago. Could they have used the wrong oil? Too thick a grade? I have heard several other possibilities - the 'oil control valve' I think, or the valve lash being out of adjustment - but wouldn't either of these be constant issues? I'm hoping it's just oil related, which could be fixed easily..

My 2011 Forester makes a rattle sound each time I accelerate either uphill or on level ground. The sound is reminiscent of the pinging sound from cars from years ago when we were told to use a higher octane gas. It's only at the start of the acceleration, not continuous. The sound seems to come from below the car, either under the hood or under the body, not inside the passenger compartment. Most websites say loose heat guards, but this would mean I'd hear the rattle throughout the acceleration, wouldn't it? Brought It to the dealer twice and they couldn't hear anything. No surprise. I hear it with my 2013 Legacy also.

I just bought 2011 Camry 2.5 6auto with 57k miles on it. The car make a rattle noise for a second or so on a cold start when sets overnight. I took it to the dealer yesterday and they replaced the timing gear assembly under warranty. This morning when I started the car in the morning it made the same rattle noise. I am going to take it back to the dealer next week.
My question is has any one had this rattle noise? if so, did the noise go away after the dealer replaced the cam gear? Also, Do you think this rattle will affect the engine in the long term?

I've been living with a rattle in the rear shelf since ~6k miles. When I took the car in for an early 15k service, I told them about it. It rattles whether the radio is on or not, so it's not speaker vibration. The tech heard the rattle, but did NOTHING to try to fix it. I was told by the service writer that since I was past 12k miles, it may or may not be a warrantied repair! He said that if the part is broken, it would be covered, but if it simply needed an adjustment it would NOT be covered. How do you adjust a rear package shelf???
I called Hyundai and was told the same thing. The girl at Hyundai said they go by what the dealership says. It was almost like she was saying "wink, wink - have the tech say the piece was broken and we'll pay for it." I'm supposed to authorize them to tear the car apart not knowing what reason they'll give for the rattle. It's an intermittent rattle, so I've been tolerating it.

I'm up to 102k on my 2007 Azera Ltd. In the last two weeks I started getting a grinding/rattle type noise when I turn my AC/Fan up to the higher levels. When it's on low/mid you can't hear anything. Does this mean the compressor is starting to go or is this something else going on?

I read at Edmunds that some customers were having problems with the sub woofer causing a rattle whenever they were playing a song with heavy bass. They took it too their dealership and the dealer just told the customer to turn down the base.
That clearly is NOT a fix. It's more of a work around. I was having the same problem with my Azera. As I like my music with heavy base and quite loud, this was becoming quite annoying.
I decided to investigate the problem and discover that the door to the baby seat anchor on the driver side was sitting on the metal underneath the headboard. I got some weather stripping and cut out a couple of 1 inch strips. I then stuffed them under the plastic cooler which surrounds the baby seat achor. My sound system is now clean at any volume level.
If your having a similar problem, open the doors to your baby seat anchors and gently pull up on them. This will pull the head board off the metal underneath. If the rattle goes away, you'll know where to place your weather stripping.

Traded my 06 Sonata for a used 2012 Azera Tech last month
White with chestnut, 23k miles. Went 12 rounds with the dealer . We finally came to an agreement.
Only one complaint with it. The steering is lousy. Feels numb, wanders, constant attention needed. Very tiring.
Wanted an Azera when I bought the Sonata, but price to much. So while I'm disappointed with the handling, (even the wife noticed the steering ) the rest of the car lives up to expectations.

I started my car last evening and it hesitated and balked and the check engine light came on. It started fine this morning, but would not go above 30mph even with accelerator down all the way. I checked the diagnostic codes from Bluelink and it said there is a possible condition with my Engine Control System and should be checked soon. The car only has 4,000 miles and has been fine until now.

I Have a 2000 Passat 30 valve v6. I got a low oil pressure message figured I could make it to the store for some oil. Well I turn a corner and heard a valve rattle and the car started to idle rough. I was two quarts low but the noise and the rough idle still exist. In neutral the noise is not noticeable. Driving the noise is only noticeable at high RPM. The car doesn't smoke and otherwise runs fine.
