Sonata I45 (YF - 2011+) :: Startup Rattle Noise Quits After 2

Santa Fe (CM - 2007-12) :: 2011 - Loud Rattle On Cold Startup For 3 Seconds

2011 Santa Fe 3.5 L

I've isolated this rattle down to the cam phaser( CVVT) in the right cylinder head. It rattles bad for 2-3 secs on cold start or after it sits for 3 hours.

I've put in 5w20 synthetic oil and synthetic Lucas additive and it cleared up the noise for short interval start ups.

I changed the cam phaser in the right head with a used one ( 40k ) but it didn't make a difference. I should change out the attaching cam as well.

Sonata I45 (YF - 2011+) :: No Startup Until Keep Start Button Pressed For More Than 10 Seconds

I cant start the sonata 2011 unless I keep the start button pressed for 10+ seconds. It just doesn't start anymore by just pressing the brake and hitting start button once. I figured before I replaced the brake light switch, is that's what causing this problem?

Sonata I45 (YF - 2011+) :: Engine Quits When Brakes Applied

Car started fine but stalled on first brake application with the skid-control light illuminated, restarted fine but stalled again on next brake application (skid-control light stayed on). Decided to head for the dealer which was only a few blocks away, drove there knowing that it may stall when brakes were applied (engine would start, idle and operate when driving but the problem would only occur on brake application.... approx when the transmission would down shift to third or second gear). My last stop before turning into the dealer's parking lot, the engine quit and refused to restart.... finally came back to life after about 5mins and was able to complete my somewhat dangerous trip (whole journey was on very quiet back streets). At first I thought it could be related to the infamous brake switch but the service rep informed me that they couldn't communicate with any control module with the scan tool. Now I sit and wait, hopefully they will call with some good news soon.

Sonata I45 (YF - 2011+) :: Glove Box Rattle And Knocking Noise (when Reversing)

I drive a '11 Sonata GLS and experience the rattling noise/clanking when weight shifts to the front-right of the car or when i go over a dip, and the noise is coming from the passenger side of the vehicle. I THINK it is the glove box issue that has been mentioned before and I am going to purchase some felt tape and apply this method [URL] .... that was posted here. Did this correct the issue?

And also when i reverse the car (specifically when I turn the wheel to the right) I get a knocking noise, which seems to also be coming from the front-right (or back) I can't tell. Can this be an axle? I'm at 79k mileage so the dealership wants $125 to diagnose the problem and that amount will go towards anything needing repair. Should I take the car to another shop instead?

Sonata I45 (YF - 2011+) :: 2013 Steering Column Rattle Noise

When going down the road I notice a rattle noise coming from the steering column area. I took it to the dealer a week or so after noticing it. I purchased the car brand new and like I said I took it to the dealer a week after purchasing it and they said they could not find anything and said they zip tied the brake lines or some bs hoping that would solve my problem.

It is now kind of obvious and I am going to take it back in to another dealership that has a better reputation.

I took a video last night so you can hear the noise I am talking about.

Sonata I45 (YF - 2011+) :: GLS Exhaust Loud Metallic Noise (buzz / Rattle)

Just purchased a pristine 2011 GLS with very low mileage. The car is essentially mint (garaged + well cared for by previous owner), but has one, occasionally noticeable issue: once warmed up, a very loud metallic buzz/rattle noise is heard from the rear of the car, particularly under low RPM acceleration. I've had many cars in the past with similar noises, which all turned out to be loose heat-shields at various locations along the exhaust systems. With this in mind, I've felt all the heat-shields on my "new" car, and they all seem to be securely in place - though some (especially the rear one over the muffler) seem to be minimally supported by design, and could potentially be resonating with certain exhaust frequencies.

Santa Fe (CM - 2007-12) :: 2011 - Timing Chain Rattle Upon Startup

I have a 2011 santa fe limited with the 3.5 and 35k miles that has a noisy timing chain rattle upon start up after sitting for a few hours,it's my understanding that the cause is no oil pressure to the tensioner because the oil drains back into the oil pan after sitting for a while. Is there a solution for this situation like a spring loaded tensioner-it seems to me that replacing the tensioner and chain does not solve the problem.

Sonata NF (2006-10) :: Ticking Sound At Startup For 1 To 2 Seconds - Filter Changed

I recently bought a 2006 Hyundai Sonata 3.3 V6. Had another issue related to the rear wheel, which I fixed. Today, I changed the oil filter on the car (along with the oil). I have heard this engine noise before, but with the cover off it appears a little louder. It's basically a ticking sound.

The engine uses no oil, and has no other leaks. It has some noise on startup for maybe 1-2 seconds (like a loud lifter or something, but it goes away in less than 2 seconds, and at the same time the oil light goes out). I changed the filter today because I was told that a leaky gasket could result in the Filter not retaining oil between starts, causes some minor knock for a few seconds.

But anyway, this other ticking noise seems to be regular, regardless of condition. I have heard some people say that some engine noise is normal for this engine, but how about this?

Azera HG (2011-16) :: 2013 - Startup Rattle When Car Has Been Sitting For 30 Minutes And Longer

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 ....

Sonata NF (2006-10) :: Rattle On Startup - Chain Stretched Beyond Limit Of Tensioner

My 2006 2.4l Sonata automatic has just past the 100000km mark and developed a rattle on start-up. Opened it up and the chain has stretched beyond limit of the tensioner and has destroyed the adjacent oil spray nozzle that sprays oil on the sprocket.

This should be a lifetime item? No abnormal usage, normal city driving, all services done, never run low on oil-strange or not. Why this has happened.

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?

Sonata I45 (YF - 2011+) :: High Pitch Whining But No Startup

Car wouldn't start, would just kind of do a high pitch whining. Bought new battery and still does it. It might crank right up or take up to 5-6 times. I'm a second owner and I believe it is the starter.

Sonata I45 (YF - 2011+) :: Steam / Smoke From Exhaust At Startup

How steamy the exhaust is right after a cold start? I have always noticed it in my passenger mirror, but yesterday I decided to stand behind the car and watch it right after starting it up, and I actually saw a few puffs of black smoke coming out with the steam. I'm not losing any coolant, so I think all of this must be caused by the engine running extremely rich when cold, the fumes were pretty bad too. Once the idle settles down the black puffs go away, but the steam lasts a good while. I have never had a newer car run so rich that it caused black sooty smoke.
