Sonata I45 (LF 2015+) :: 2.0 Turbo Sound On Cold Startup
Dec 25, 2015
So I brought the Sonata home and she sat in the garage for 5 days as I was traveling. Then when I got back, I was so eager to take her for a drive. At this point she only had 72 miles on the Odometer. When I started her up, I thought the engine sounded rougher and louder than usual. My other car is a Turbo Diesel and that does not make this loud a clatter. After a few minutes of idling and driving, the engine quietened down quite a bit.
Video of the sound at cold start up.

"Sometimes" when I start my car (2015 2.4L GL base) there is a clunk like something is disengaging or engaging i.e., torque converter or transmission.......??

Seeing issues with A/C not getting cold? I thought it felt a little warmer than it should, and then my wife got in my car and instantly called it out, and now it is pretty close to room temp. air....Could it be low pressure in the lines? Or the fluid itself (freeon...? =s) ?

Need to determine the noise before I took the vehicle in to be serviced. I don't know if I would necessarily describe this as grinding...to me it doesn't sound like metal on metal..but it's not normal.
Only happens on a cold startup, and even then it hasn't been 100% of the time...probably 80% of the time though.

I found this thread, Grinding Sound On Statup but not sure it's the same issue. This just started. Vehicle has 150K miles on it.

I have a 2008 Hyundai Sonata 2.4l with ~235,000kms (~147,000 miles). It has been well maintained and has been a great car. It has been developing an engine tick noise at cold startup and it seems to be very gradually getting worse over time. This noise is most evident immediately after strarup and gradually dimishes over a period of about a minute and varies in terms of how noisy it is and how long it lasts. This nopise is never heard when the engine is warm. From what I have read online, this can be caused mainly by two things:
- use of an aftermarket oil filter
- timing chain tension insufficient
Late last week I changed the oil filter out from the Purolator Classic filter that I have been using for years to a genuine Hyundai oil filter. This did not make any noticeable change in the tick noise so I do not believe that this was a contributing factor.
Over the weekend I removed the valve cover and checked the timing chain tension. It was taught as it should be. I could push it down a bit between the camshafts but it would spring right back up. I also used a videoscope to look down inside the cam tunnel and found no evidence of the timing chain contacting any metal or the oil drip line for the lower timing chain sprocket. Everything appeared to be in order.
When I started the engine to confirm no leaks around the valve cover, I used a mechanic's stethoscope to check for the noise. I was unable to isolate it as the engine tick did not occur at that time. The cause of the tick noise continues to elude me, but I have ruled out the two common causes (oil filter and timing chain tension).

I have a Limited with auto-climate. Temp is at 73 outside temp is 90. So obviously it is not just sucking in outside air. But with the AC light on I can tell the compressor is cycling as it pulls on the engine and vibrates the car more than if it is off. But with it off I am still getting cold air. How?

When I test drove a Sonata Eco last week, I noticed that the AC only pumped out cold air when it was on the "Max AC" setting. As soon as I moved the knob up a bit - still well in the blue territory, mind you - warmish air started coming from the vents. Basically felt like just the fan was on. Power-wise, it was set to "2".
Is this something that's common among Sonatas, or Eco's in particular? Or is this possibly just a result of the car sitting on the lot for a while, and maybe the AC needs a recharge? Living in Florida, good AC is obviously an absolute requirement, and I shouldn't need to keep it on Max all the time just to ensure cold air.

FSI engine ... I am getting this ticking sound on a cold startup. I've had the timing belt tensioner fixed under warranty and it went away for a while. However now the ticking is back. To be honest its embarrassing to start my car cold in front of others.

I have a '06 sonata 3.3 v6. Let me first describe what was happening to the car before the noise started. When I first started the car and put the ac, the first time turning the steering wheel in either direction the steering wheel would tighten up and the battery indicator light would come on and the fasten seatbelt light would flash even though I had the belt fastened. It would only happen the first time I would make a turn and after that I could turn with no problem. So in recap, it would only happen on the first turn and only when the ac was on. Now when I start the car up there is a noise coming form the pulley/belt area. I wouldn't classify it as a squeaking noise more like a grinding. I've looked at the belt and it seems to be fine. After I start to drive the car the noise goes away. If I start the car again after a drive within about 2 hours the noise doesn't happen when I start it. What this noise could be? and also could the noise and the steering wheel tightening when the ac is on be connected?

My 06 Sonata runs very rough at start up when the car is cold. It appears that it is missing on several cylinders. This last for about 15 seconds and then the car runs fine. What could be causing this problem? No check engine light.

Noticed that when drive Sonata cold without having it warmed up and you hit the accelerator even a little bit that it 'jerks' back a bit? Once the car is warmed up you don't feel it anymore.

I recently got a 600. On cold startups there are times when it makes a horrible clanking sound when it does its ~2 second low idle. The instant it goes to high idle the sound goes away. After the car has been run, I don't hear the sound again until the next cold start.
This is not normal injector click, and if it is valve click there must be a side issue causing it. Like an oil primer working intermittently or something.

The car has a rattling sound on start up and I read here that is the timing chain tensioner. The quotes for fixing it has been huge(from 900-2000 just for labor).
And I changed front struts and had Monroe put on the car, the ride is very soft and a bit bouncy. I had a 2004 Altima and the ride was very stiff and I loved it. By the way, the car is a 2006 V6 with 111000miles.

I've been noticing a metal type 'clanking' sound whenever I am gently accelerating up a hill on my 2.4L.
It doesn't happen all the time though. It's not the usual GDI ticking sound. It can be heard when the windows are open but yet I can not tell where the sound is coming from. It doesn't happen enough that I can replicate it so I haven't taken it in for a check. The car drives fine though.
Sounds when going up a hill? Not sure if it's from the engine or from the transmission getting confused trying to change to the right gear. Perhaps the sound is just normal...

I am a proud and recent owner of a 2015 Sonata Sport 2.0T!
Car looks amazing and am very happy with it.
But lately I have been noticing lots of drone noise coming from the engine, and a really loud cold start as well. The "cold start loudness" goes away after a little bit of driving.
Was wondering if this is just the way the 2.0T sounds, or should i get it checked?

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?

A lot of videos have audio of a knocking sound, however my sound is more akin to an extra crank of the starter. It's intermittent at best, and I thought it was actually use error until I noticed the sound occurred a few times even when I briefly cranked the engine.

I hear a bit of exhaust leak noise from engine compartment only at a cold startup, it goes away in seconds. I am 700miles from home. If it's a nonessential fix i will drive home before fixing, or, if an easy gasket replacement, I have two more days here, and tools,garage, and competent support to diy the job.

According to the manual the high pitch sound is to let driver know that the pads are worn out but i checked and my pad still very thick after 15k miles.?

I have been having a grinding/metallic sound when going up hills in 4th/5th gear. It sounds like if you threw metal into moving parts. I believe it's coming from my engine or transmission. When i was at the dealer last month for a campaign and ecm upgrade i mentioned this problem and they replaced the vcm motor assy, however the problem still exists. What could be causing this problem?
