'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.
View 5 RepliesIn the last few weeks, as AC season started, I notice a very bad smell, It comes out of the vents for the first few minutes of running and than its gone. Every time I start the car.
View 20 RepliesMy 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!
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.
View 5 Replies 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.
View 2 RepliesI have been getting exhaust in my car cabin since last fall. It is worst when I first start up the engine. Once I get driving, it's not so bad. Switching off the heat or recirculating the air does nothing to change things. I used a CO detector in the cabin and the alarm didn't go off, but it still worries me that I might be breathing in carbon monoxide. And none of the shops have been able to diagnose it, let alone fix it. The first shop installed a new 'flex pipe'. The dealer thinks it's coming from a gasket near the flex pipe. The exhaust manifold is not cracked. A muffler shop said there was no leak. Is it possible that exhaust is somehow getting mixed into the air via a faulty valve or vent?
View 6 RepliesWhen 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.
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.
View 17 Replies11' 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 have a question with aftermarket exhaust (particularly JoeZ and Borla) I was wondering after you installed the exhaust do you now get increased exhaust fume smells in the cabin when the windows or moonroof is open? When I had my 350(F-sport exhaust) I couldn't cruise with the moonroof open without filling the cabin up with fumes.
View 14 RepliesOnly had happened a few times in the last month. I start the car and it idles okay. drive down the road and then come to s stop and there's some blue smoke. It smells like burning oil. it only has happens 2 times in the last 2 months. only when its really cold it has happend. If I rev it when its happening I can see a big plume of bluish smoke and it smells like burning oil. after i drive after that no more smoke.
car has 95k on it
never been chipped
car has full turbo back and intake
car does not burn any oil between oil changes. oil stays at the same level.
did break an oil pan about 4 months ago. when I replaced it no signs on sludge.
turbo boosts fine
Car has had a rough idle for a long time. only when its a cold start and only last about 20 seconds. When I boost it or redline the car which is very rare no smoke at all. I have always kept the oil more on the high side of full. I usually fill it right to the high mark on the dip stick.
I have a 97 f 150 with the 4.2 bad miss on # 6 changed plugs and wires still missing. Also have a bad tick and exhaust smells like fuel. Check engine light is blinking.
View 10 RepliesI have owned my 2005 v10 ex since 60000 miles. Have had many dependable family road trips and love my truck.
Recently it has started puking coolant and the overflow tank smells like exhaust. The oil cap has some coolant sludge on it. But there is no coolant mixed with the oil. Or oil in the coolant.
I am pretty certain these are the signs of failing head gaskets. The truck has 193000 miles on it now.
Want to keep it on course. But keep it reliable. So do I buy new engine or do I just replace head gaskets?
1990 Ford Aerostar. When I start runs really rough and has excessive fuel consumption and the exhaust smells like gas and has a misfire my friend says its the coil pack going bad im not sure. I love my ford aerostar dont wanna get rid of it.
View 5 RepliesI have a 2011 Camry. When you turn on the vent the air smells bad, kind of a musty fowl smell. When the a/c is turned on, no smell. I changed the cabin filter a week ago and no luck.
View 3 RepliesNewbie hear to the 6.0L's. But I'm learning an awful lot really quick from all of you here. I've read lots of tech stuff on these EGR Coolers, oil coolers, FICM tests. This is what I got happening right now.
2004 F-250 6.0L. Today was 45 degrees in Reno. 5400 ft elevation. Tried to start it without block heater. Would not even crank. It tried to crank but sounded like it locked up on first crank. Tried again, nothing. Same. Tried yet again and finally got to getting the engine to crank, but wouldn't start after about 5 seconds of cranking. Waited a little while not wanting to burn out my FICM, then tried again. Same as previous, would crank but not turnover. Checked batteries. Both were over 12.3 V cold, motor not running. This next time, turned key on and let it sit in ON position for about a minute. Then cranked and it took about 5 seconds and then the motor finally cranked over. Lots of black smoke as usual for a cold start like this. Battery volts after cranking over and running were now both over 13.6 V.
Keep in mind the truck has started better than this before in 15 degree weather just about a month ago.
After it started I noticed what appeared to be oil/coolant residue directly underneath trucks transmission area. It was not tranny, but in that area. I got under the truck and can see this fluid coming from EGR Cooler area.
Now for the smoke. Just stared smoking on start up. White smoke. Then it would disappear as engine warmed up. Now its constant white smoke when warmed up and applying the throttle. Smells like coolant coming out of exhaust. Not diesel.
I parked truck facing downwards on my driveway. Then I checked EGR Valve. When I pulled it it was WET. Not dry. Peeked in EGR Valve hole, didn't see coolant. Just wetness. I did change gasket and rings on it the day before as well.
As for FICM, it reads 47.9 Volts on key turn, 48.1 on cranking and 47.8 running. FICM good by all standard 6.0L literature. Degas bottle passed pressure test holding near 15 PSI for 20 minutes! No oil in degas bottle that I can see.
Truck is stock. Is my egr cooler and oil cooler shot? Would a bad egr cooler or oil cooler cause this awful cold start? When I plug in the block heater, it starts NO PROBLEM, but still white smoke. Also, NO loss of power at any time.
Just curious, in comparison to other vehicles, does it seem that the rear window defrost works pretty slow in your Sonata? I park outside and notice it is slower than I would like for it to be in the morning. Heated mirrors work great.
