Sonata I45 (YF - 2011+) :: Ticking Sound During Hard Acceleration And Smoke From Exhaust
Dec 15, 2015
11' Non-Turbo 2.4 with 145k Full Synthetic every 5k (Done me or provided to the quicky lube) Around 80K about 2 weeks after taking it in for an oil change my wife heard a ticking sound coming from under the hood. Pulled over and there wasn't a drop of oil on the stick. It started with about a qt every 1000 miles or so, now it's to the point that I have to put a qt in about every 3 days (1-200 miles)
We cannot see oil anywhere, last I checked the plugs had carbon build up but were not wet. (Recently) We also hear a ticking sound during hard acceleration and a good bit of black smoke coming from the exhaust.
We still owe 5k on it, it's our first new car and I'm terrified the thing is going to blow up before I pay it off. Tonight as I was about to get in the car with her I heard the clicking sound again but this time it was full (just added some yesterday). I have compression and leak down testers, know a little bit but I am nowhere near a "mechanic".

I've had my car almost two weeks, but today is the first time I've driven it with the radio off. I noticed some ticking coming from the engine during acceleration, and maybe it's my imagination, but it seemed more pronounced with the ECO mode turned on. I know these GDI engines are supposed to tick at idle, but is it normal to hear it during light acceleration too? My oil level looks fine.

So this only happens one time a day when i do it. It does not matter if it's early morning or afternoon.
I pretty much give full throttle and i see in my back mirror grayish smoke coming out of the exhaust, kind of like when you are on a very dusty road. But i do it again right after or 10 minutes later and it does not happen again until the next day. Then it's the same deal.
I'm not doing anything different.. I do my oil changes every ~4k miles i drive mostly city with barely any stop and go tho. Is this something i should worry about and go see the dealership? Or is this because it is a GDI engine?
I did not have this with my old car even at high miles. But then again my old car was no GDI. I am currently sitting at 24k miles.

My 2011 Sonata is now at 56000 km (35k mi). While driving with a friend, I floored it when entering on the highway and he told me there was some dark smoke coming out of the exhaust.
I take very good care of my car and recently started using supreme gas and synthetic oil. It runs very smooth and never really had any problems... should I be worried? Is this normal?

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.

I recently purchase a 2011 Sonata. It sounds like there is a rattle in acceleration coming from the exhaust (passenger rear)
I had the just alignment professionally checked, and it's spot on, but it seems to pull to the left still.

I recently purchased a 2011 F350 chassis cab with no bed installed. Have a few questions regarding the exhaust system. When I inspected and drove it noticed some black smoke when under hard acceleration, nothing major though. Other that that the truck drove great. Have not got the truck home yet, a friend is going to pick it up and deliver it in a few days. Based on the visible smoke I was suspicious of the exhaust system but I have no knowledge of what the system is suppose to look like. My experience with diesels and for that matter gas engines is mostly from the days of mechanical fuel injected diesels (70's era farm tractors mostly) and carberated gas engines.
My friend stopped by a local Ford dealer and crawled around under a new 2015 Chassis cab to look and compare to this 2011. It appears that the SCR and DPF are not installed on this truck. Where they would normally be is a section of pipe with a section about 2 feet long that is 6 or 8 inches in diameter. Looking at some threads on this site I'm guessing this is a muffler that has been added since the truck is not loud. There is no DEF tank and all the wiring for sensors that would be attached to the exhaust system appear to be tied off to the frame and not connected to anything. The dealer didn't know the history beyond he purchased it on an auto auction and he installed a new rear end in it. Car Fax shows nothing of concern.
My question is should I now be concerned since have determined much of the exhaust system has been removed? I've read some threads and it appears that the only way this can be done and have the engine run well without any codes etc is if the removal is done with some sort of tune. Is there any way to determine who has done the tune? Will it be an issue when take to a Ford dealer for service?
I know if wanted to put the system back to stock would be large dollars, as long as the system runs well and is reliable I will be happy. The anticipated use of the truck will be to pull gooseneck trailer and will probably not see more than 1000 miles a year towing and 5 to 10k total in a year. I drive with a very light foot seldom ever pressing any vehicle to its limits. If still have the truck in 10 years when retire or at least cut back on my work then it may see more miles.

Driving to lunch today I pulled out on the highway and accelerated hard. The Sonata didnt want to shift higher than about 4th gear (auto trans w/ the "slap stick" that comes standard. I laid off the gas and the car seemed to be running fine at that point. 1/2 mile down the road the car just died. I pulled over the car restarted fine. At this point it didnt want to shift well and died a couple times. I stopped for lunch. Afterwards I took it easy, car acted fine. Outside of work I accelerated hard again and the same thing started again.

My 2011 2.0t has developed an odd ticking sound from the engine bay that is audible when idling. I haven't been able to pinpoint the source of the sound because once I drop the vehicle in Neutral it goes away although sometimes I do hear random ticks when I do this. The ticking sound is intermittent and sometimes I hear nothing.
In the video at 11 seconds the ticking starts. At 18 seconds it ends as I drop the car in neutral. What this sound could be? I'm going to try to hit the handbrake and check myself or have someone in the drivers seat while I go check but have yet to truly pinpoint the source of the noise.

It's winter here and as my car warms up it starts to tick. It doesn't happen right away, only as the car warms up and it gets progressively louder until a certain point at which point it seems to stop (or has faded significantly). It primarily happens in idle and in gear but will go away after revving above a certain point (around 1500-2000rpm). If I put it in neutral the noise is greatly reduced or disappears completely unless I rev it from about 1000rpm-1500rpm. Once the car reaches operating temperature the noise is gone. What it could be? The sound appears to be coming from the top of the entire. Also, it doesnt seem to do this when its warm outside. I have a 2011 sonata GLS and I change the oil every 3000 miles. I use either Bosch filters or OEM filters so I know the filter has nothing to do with the ticking.

When I turn my car off there's quite a bit of noise coming from under the car. Basically the sound of the exhaust cooling off but I would say a little excessive. In fact one night I was dropping my son off and left the car running and went to get some stuff out and while it was idling you could hear it. Clink.. clink clink. Same sound when its turned off.
I backed the car up on some ramps yesterday after I had driven it a short distance to see if I can pint point where its coming from and It seems to be in two places. Both where the exhausts are bolted together at a flange. One where the Catalytic converter bolts to the pipe that leads back to the mufflers. And there the 2nd source where just after the Y pipe where it splits off into 2 mufflers.
Is this something that may subside after the car has gotten some miles on it? I'm still well under the first 1k miles.

Exhaust tick really bad under acceleration when its cold. It goes away after the car is really warm. Im thinking i have an exhaust leak that is closing up when the exhaust warms up.

Not long ago my wife said the air recirc doesn't work any more on our '04 V8 and I had to admit that I agreed. After a little investigative driving, I noted that heavy acceleration (or uphill climb) causes V8 to tick (can hear it reflecting on passing walls, for instance) and strong smell of exhaust in cabin.
I thought it might be a manifold/exhaust system leak causing the noise and the exhaust smell. Seems to be only when driving aggressively or climbing. Soonest the local dealer can see it is 7/21 (16 days from now). You think it safe to drive?

I am getting a ticking noise under hard acceleration. Dealer told me the exhaust is touching the heat shield but did nothing about it. It's driving me crazy...
I may have to pull the trigger on this Borla I found for 700 shipped and new. Trying to keep my promise to myself to drive the car stock for a year b4 any major spending. That's out, I can already tell.

My 2011 Dodge Journey, V-6, auto, awd, pulls hard to the right on hard acceleration. It always pulls just as the transmission shifts. My dealer's service manager said its due to the front drive shafts being different lengths and torgueing differently.

I recently purchased Sonata NF 2006, with L4 engine with 108 miles on it. I noticed that mpg is very low - 16-17 50/50 city and highway. The engine runs smooth and pretty fast for 4 cylinder engine, there is no smoke coming from the exhaust. While driving with A/C on i did not notice any pressure on generator or anything like that.

After posting about the smoke upon hard acceleration, some of you stated you had the motor checked for "low compression". So, my question is what symptoms was the car having for you to take it in for this diagnostic test?

Ok so the wife and I were heading home, she was in her 2.0t sedan, I was in my 3.6 4motion wagon. I got stuck behind a slow driver on the highway (doing 50 in a 70 mph zone) so I get in the passing lane and I floor it to pass him. When I get home, my wife tells me she saw a good amount of black/blue smoke coming out my tail pipes when I went to pass the other driver. This is on a engine with 2400 miles.
I take a look, and the chrome exhaust tips I had installed not long ago are now all black, covered in a oily thick residue. These same exhaust tips were on my previous 07 3.6 4motion wagon for 10k miles and was still shiny when I took them off. but after about 1k miles on the 08, they are now all black. I check the oil and it still reads full.
So what could this black smoke and this oily residue on the exhaust tips be caused by? should I be concerned? Engine runs fine with the exception of sometimes stalling when trying to start it after a short stop. (VAG-COM doesn't show any error codes logged.

I have the classic ticking sound on acceleration. I had a muffler shop check it out and the tech said he thinks the passenger side exhaust manifold has a leak. I have already replaced the whole manifold and cat on the drivers side. Could it be just the gasket? The ticking is coming from the top near the engine and not the cat. Is it a pain to replace the gasket?

As I was driving today on the highway, I saw a whitish cloud of smoke come out of the exhaust.......the car seem a bit wobbly after that. It only happened once. the ring around exhaust tip is all black. I am not sure if it has damaged anything? What it could be?

If the exhaust manifold gasket is broke / cracked will it making a ticking sound?
