Sonata I45 (YF - 2011+) :: Idling And Clinking Sound - Exhaust Are Bolted Together
Mar 18, 2013
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.

I get clinking sound from my left wheel when I steer left or right. A mechanic here says wheel bearing needs to be replaced. I am sure that is the problem but he says for the replacement (Total along with the bearing).

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 recently purhased a 2012 Camry, and hear a crackling noise from around the exhaust area as soon as I start the car and during idling. The noise is not too loud, so can be heard from the driver's seat only if the AC is off, windows are down and if the outside environment is relatively quiet. However, when I get out of the car and stand near the exhaust area, it is quite audible. Drove 4-5 miles and stopped and the noise still existed during idling. I'm not sure if it exists while driving as it may not really be audible at the driver's seat. Is this normal or do I need to get it checked.

Noticed the condensation from the exhaust seems to only exit on the left muffler when the vehicle is idling?
Is there an actuator that turns the right side unit on under heavier acceleration?
BMW uses an actuator on their exhaust system that opens up to create more airflow when above a certain RPM.

I have noticed with my 2011 Sonata that I am experiencing the reduced power and a bit of*rough*idling from the engine. I noticed an increase in performance after oil changes, then back to the same issues after about 1000 miles. I switched to a synthetic blend and started buying the best filter any of my local shops carry. I then ran some additives recommended and shifted to gas from Shell o However, I am still having the issue.

I have a 2011 Sonata GLS with 86k miles. Sometimes, like once every 2-3 days, when I start the car, nothing appears in the box that says "P, R, N, D". The transmission also acts very strange. I often don't notice the blank box when I start the car, but immediately notice it when I put it in reverse or drive. There is an awful "clunk" from the transmission, and the car drives like I'm driving it through 6 inches of mud. I stop, put it in park, restart the car, the problem is gone.
The dealer said if it is a problem with the shift lever, that is not covered under the drivetrain warranty. I really don't have the money for the dealer to do expensive diagnostics/repair.

When I'm idling my car at a stop, I notice a slight vibrating through the car... The vibration could also be felt through the steering wheel.
Not a major issue. Tried pushing car into neutral to see if it made a difference... Nothing.

My 2011 Sonata smells like exhaust inside the cab of the car unless I keep the button pushed for "inside air circulation".
I called the dealer and as it turns out, this is a common problem with this model. A hose has to be replaced on the exhaust system.
I knew I was smelling exhaust and also knew there was a problem with the car/exhaust!

'13 Sonata with only about 8500mi. When I put the front defrost on, the air starts to smell like exhaust. This is not only while stopped but also driving. The only maintenance done so far are regular oil/fuel filter changes - last one was within a month ago and didn't notice this smell before, though we didn't use defrost for fall.

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?

I just had my JUNBL exhaust installed over the weekend. Problem is, the left exhaust tip is touching the bumper. I was thinking of cutting the bumper part where it hits or changing the rubber mount to a longer one to bring the muffler lower (dunno if I can find a longer rubber mount) Everything was installed on the stock location of the stock exhaust with no modifications. Pictures attached. 2nd picture is on the left. Although not hitting the bumper, might have to modify that as well.

My car if left on in park for 3-4 minutes starts to have a heavy smell of something... Is my car running a little rich or is there a more serious underlying problem?
RPM of car idle is 750.
And car doesn't smell like fuel when I'm driving, only if I leave the car running for a while and it sits there does this smell begin to build up.

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.

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.

Pretty much as it sounds, when i hit a bump up, not a pot hole, it makes a clinking sound like almost a up and down clinking.

My front right or left or both for that matter, (its hard to pinpoint the noise while driving) makes a clinking noise when I hit a good size bump. No noise at all on smaller ones?

This has been driving me crazy for the last few weeks. I think my car is making a relay sound, but what it's for. Somewhere in the dash, behind the steering wheel and bezel, on the left hand side, there is a relay clicking on and off every 5-6 seconds. I'm thinking it's for my rear wiper, which I believe my wiper motor is busted. However, I don't know for sure.
So, two things here.
1. I want to figure out which relay it is. Looking for electronic schematic for a 03 w8 wagon?
2. How can I determine if my rear wiper motor is blown?
To be honest, I can't even figure out how to turn it on because the on/off switch for the rear wiper is locked in place. I only hear the noise when I'm not cruisen' with my windows down or when the stereo isn't bumping.

I was driving this morning after doing a brake job (nothing to do with the problem, just anger coming out) made it about 10 kms and noticed when i took my foot off the accelerator, the heater fan powered down a bit, and back up when I gave it gas...noticed a knocking sound from the engine...pulled into a gas station and put it in park. After a hard time idling, it cut out. I started it again and the idle was not good at all. kept cutting out. Got it going and made it home with the same sort of power issue. Tried to start it a couple times and same issue with the idle. Sputtering quite a bit and noticed quite a bit of exhaust coming out. When I backed it out of the garage, I noticed a small puddle of oil.

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.
