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?
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.
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 a 95 Cherokee and dark smoke is starting to come out of the exhaust, but only when I make a u-turn. The Jeep is running fine, except for the smoke and I noticed the problem about two weeks ago. While the Jeep is running there is absolutely no smoke, but as soon as I make a u-turn a cloud of smoke comes out the back that smells like burnt rubber.
View 1 RepliesI 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.
View 10 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 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 have a 2001 echo with 140000kms on it, nothing ever has gone wrong with it. But I now have what sounds like a exhaust leak. I cant find any holes in the pipe anywhere. There is some dark residue that looks like it is coming from the exhaust manifold gasket. I replaced this but the sound continues. Do i need to get the manifold completely out of there and plane the mating surface of the manifold smooth. It looks really pitted right now?
View 7 RepliesI am driving 2013 Sonata for over 13 months, after 2 Synthetic oil changes, I have noticed that colours of oil turns darker after only 1500 miles each time, first synthetic was Quaker State and currently Castrol synthetic.
My Question is, what is the reason that causes the oil to turn dark,what is that substance which goes in oil to make it dark. My previous car Honda Accord could go 7,000 miles without any change in synthetic colours. Whatever it is which causes oil to get dark, cannot be good for engine.
I am being forced to change synthetic oil after 2000 miles. Do not want to drive my Sonata with dark oil. What causes even synthetic to turn dark after 1500 miles. Also why synthetic oil stays clear upto 1500 miles.
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?
View 6 RepliesAs the title states I have lots of blue smoke out the exhaust and the smell of burnt oil. Checking other posts it looks like it could be a diverter valve, a pcv valve or the Turbo. I checked on line and autozone and parts America say these are not required for my car. I checked my Hanes manual (yes, that's all I have) and they don't have the DV or the pcv listed.

I just purchased an '06 V10 a couple weeks ago. Today, I was about 11miles into my 15mile commute when I noticed A LOT of white smoke coming out of the back. The only time I'd seen smoke like that before was just before my old Ford Explorer caught fire. I immediately pulled over and took a look. White smoke (maybe steam?) was billowing out of the exhaust.
I say steam, because it didn't have the strong diesel smell I would've expected. I decided I couldn't sit there parked by the highway, so I got back in the car, checked warning lights and pulled out. Within 1/2 mile, it was gone. Nothing. No more problems the rest of the way. What this might have been? I have 1100 miles on the vehicle and this is the first time it's happened.
My dad was driving behind me and said that black smoke was coming out of the exhaust, is this normal???
View 7 RepliesSonata 2007 3.3L V6 ... I have nearly 70K on my Hyundai, and I am the original owner. Everything was fine until 24 hours ago until I got a knocking noise. I stopped, shut off the engine, and had it towed.
The mechanic says that based on the symptoms (knocking, some white smoke from exhaust) that it is powertrain warranty related, and I should be covered.
I have been searching online for days trying to find out why my car is smoking. i recently broke the oil pan on my 03 vw passat 1.8T. When I broke it I didn't know what had happened and I am sure all the oil drained completely out. The turn off engine now light came on and immediately shut car off! But I am not sure if i did in time before doing any major damage. my husband replaced the oil pan with a new one and everything seemed to be running good. i drove it for about 10 days and i noticed a whitish (I am not really sure of the color cause it was in my rear view mirror and couldn't see well) smoke coming from the exhaust as i was accelerating to get on the highway lasted about maybe 5sec then stopped. it has since done it 2 more times as i am getting on the highway but not every time. There are no fluid loss doesn't overheat when driving it all the fluids are good. I thought maybe head gasket or cracked head but husband says its not. the last it did it i stopped driving it in hopes to find out why its SMOKING!!!
View 3 RepliesI have a ton of white smoke coming from my exhaust pipe only after it ran a long time then is started back up ????
View 7 RepliesLiterally drove the car yesterday for three hours nothing was happening. Went to turn it on today when it idols a little constant white smoke comes out of the exhaust! Then when I'm driving and my turbo boost lets out a big cloud of smoke comes out. What could this be? Also just filled my car up with gas from empty today if that matters
View 7 RepliesI have an 07 Sonata V6 Limited with 65K miles. Recently I've noticed at startup, the valves pinging and blue smoke coming from the tail pipes. Settles down after a few seconds and doesn't do it again if you shut it down and re-start. Last time I experienced this was on a Silverado with well over 100K miles. Back then it was valve seals. Could this be possible with 65K? I noticed in the maintenance log that they request having valve clearance inspected at 60K. Could this be causing my condition? I'm the second owner, so the 100K warranty is out of the question.

What happened to it since it was running just fine all yesterday and before...
It's a 2001 camry Solara .. When I start my car for the first time every day, I have white smoke come out my exhaust usually for about a minute or two but it runs fine after that. But it's like a cloud of white smoke. I checked my oil and it's fine. What it could be?
View 17 RepliesI own a Lancer Evolution X and I've been having a strange issue where, when accelerating around 2500-3500 rpm a thick cloud of blueish smoke starts pouring from the exhaust for about a second or two accompanied by a loss in power. The smoke stops quickly and then it runs like normal. This only happens once in a while for a second or two. When idling there is no smoke. Or at Wot. There is no coolant mixing with oil. The oil was recently changed with the proper oil. and it still happens once in a while. I checked the turbo and there is no shaft play or oil inside of it. There is no loss of boost. Although I did see a tiny pool of oil near the turbo inlet and some more oil coating the inside of the intake pipe. is it possible that the turbo just sucks up some oil that collects at the end of the intake? the PCV line which connects to the intake appears to be letting some oil into the intake.
