Elantra MD (2010-15) :: Burning Smell From Exhaust - Huge Cloud Of Smoke
Jul 6, 2013
Ok, here's the situation... (Elantra GLS - Automatic)
I was at a 4-way stop sign. No other cars were around so I accelerated. Then suddenly, I hear and see a car coming at me REALLY fast, and well, I panicked. I floored the throttle (almost literally), and I heard something popping or maybe it was a farting sound... It happened so fast that I don't remember clearly...
Then behind me was a HUGE cloud of smoke behind me. I mean really, it covered up the whole street. It was 10 PM, so I couldn't really tell what color it was, but it seemed to be white... So I turned off my car. Checked the engine, no smoke from the engine. I started it up again, and instead to revving to about 2000 rpm at start up like it always does, it only went to about 1000, and more smoke was flushed out the exhaust.
I was close to home, and with no 24-hour mechanic shop around me, I drove home. As I drove home, I had quite a bit of smoke trail behind me which scared me through out the whole 2 minutes of driving. I got home, and I checked the exhaust again, but there was no more smoke. However, a burning smell lingered around the exhaust.

I was driving down a 2 lane road doing the speed limit and I found myself behind a car going much slower than the limit. It is one of those roads where every once in awhile the double yellow line is dotted so you can pass.
I finally got to the point where I could pass as there was no oncoming traffic, so I turned left to pass the guy, floored it, the tranny started to kick down into passing gear and then the car sputtered, didn't accelerate and blew out a huge white cloud from the exhaust and the cel light flashed on and off. The cloud was something like you would see in a James Bond film to get rid of cars following you. All of the cars behind me had to stop or slow up because you couldn't see. I didn't realize that until I looked in the rear view mirror. I thought the car just sputtered, I didn't even realize about the cloud until I looked back.

My car just turned 20k miles. I haven't abused it and rarely tach it over 4k. I needed to cross a lane in heavy traffic so I put my foot into it, it tached up to maybe 6grand, dropped a gear or so and out the tail pipe comes a huge cloud of smoke. I mean huge. Looked like it burnt a quart of oil in a second. I had just changed the oil a few days before. Mobil full syn. I know the lvl was correct because i checked it the day after i changed it.

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?

Out of the blue I started old red up yesterday (after charging the dead battery) and got a huge cloud of white smoke. Smells of coolant so Im thinking oh great a head gasket. The thing is, I can see no trace of coolant in oil or vice versa. I started it up with radiator cap off, while cranking I got a little fluid spit out the neck but once it started it was not gushing or bubbling at all.

Got a weird issue with my 2014.5 with 10k on it today, V6/2GRFE. On Wednesday I checked oil, it was at full drove it to Virginia to pick up a car and I followed it back 150 miles home, looked fine. Sat Thursday, let a family member drive it to work Friday, was fine. Saturday I drove it about 40 miles, was fine. Sunday I moved it around the driveway, was fine.
Today I started it and got a huge cloud of gray smoke out the back. Smoke continued while idling. Shut it off, got a family member to look at it (and make a video of it for future record). Basically on startup it lets out of a big puff of smoke (worse than my old V8 truck with leaky stem seals), then smokes lightly as it idles. Revved the engine and another puff came out, and the smoking did not stop. At this point I called up my dealer and wound up having it towed in as after about 3-5 minutes of running it was still smoking, as I'm under the impression burning synthetic oil is very bad for the emissions control system. Before leaving I let it cool back off, checked the oil and found it about halfway to 2/3rds between full and add on level ground. I did not let it warm all the way up to see what would happen over concern for damage.
Car is sitting at the dealer now, the manager said he'd try to see if they could get to it tomorrow (do have an appointment for Thursday); probably feel bad after the paint fiasco with the last one. Engine ran fine, seemed to be getting good fuel economy this tank, no CELS. I get that 1qt/1000 miles from break down/very minor burning is normal, but not this much smoke and nearly half a quart in 300 probably is not.
I'm also preparing for this to be difficult to pin down as first hand experience tells me oil burning can be a pain sometimes to troubleshoot, but my 91 Camry with 225k on it doesn't smoke like this, and typically valve stem seal seepage (which would be unacceptable though not serious) goes away quickly and presents much later in engine life. Not cold at all and had an oil burning smell to it for sure, but anyone have any normal expectations for what it could be? My 2012 2GR had 34k on it with zero oil use, burning or issues. If they say nothing my plan is to show them a video, and see what they say.
Pretty frustrated as I was liking this car more than my 2012; felt like it ran a little better, got a little better gas mileage, and road/drove a bit nicer too (probably the newer tires). Also had run into zero issues, whereas in the same span of ownership my 2012 already had one paint repair, a recall, and a brake light switch. Just had an oil change in June too at the dealer, verified the level was fine when I got it back, no leaks either.

My VW Golf TDI 2000 has 236,000 miles on it. The other day my husband jumped on the accelerator to merge onto the freeway, and it let out a huge black cloud of smoke. Wow, we thought. Weird. Impressive. Uh oh. Then we realized it was making HUGE diesel engine noises, which just got louder by the next day. Windows down, you can't hear yourself think. It also won't accelerate past 50 mph. We've spent so much money and time fixing this car. Would love to know what might be wrong this time. Just moved, no trusted mechanics who we can call. Might we have to donate it to public radio and just be done with it? Or something my husband can repair with the manual?

First some background. The vehicle is a 2003 Expedition with rear AC. The 5.4L engine has been replaced with a 4BT Cummins (DD since 2010), but the AC system is not altered-- other than the compressor being mounted to a different engine. The intercooler is in front of the condenser, which hurts efficiency of the AC system, but it seems to work fine in our climate.
My AC system quit cooling one day, and the problem was a hole in one of the low-side tubes from rubbing on the turbo-to-intercooler tube. I repaired this by aluminum brazing. The system held 120 psi on nitrogen for one hour. So I pumped it down overnight to 27 inches of Hg and made an appointment with the AC shop to get it recharged. I could not get an appointment for several weeks, so I continued to drive it with no AC, thinking it should be no problem since there is no pressure in the system.
I was on a road trip when all of a sudden, there was a huge stinky cloud of blue smoke billowing out from behind the truck. I pulled over and the AC clutch and pulley was smoking hot. I shut it down and cooled it off slowly with squirts from a water bottle.
So my clutch is shot but I'm not sure what caused it to fry. Is there a typical mechanical failure where the friction material can be chewed up by the pulley-hub? Or is it possible that somehow the controller commanded the clutch to engage without pressure in the system?
I think it would be prudent to replace the compressor, since there may be some bearing or housing damage from the clutch failure, so that is in the plan. I have read that when ever the system is open, the drier should be changed too. I want to do this right rather than do it again on another day.
One concern I have is that if when the clutch was failing and it managed to turn the compressor-- could there be pieces of compressor in the tube runs that I need to clean out? Other than a visual inspection of the open tube ends, is there another test or things to look for?

Our 12 elantra with 26,500 miles went up in a big cloud of smoke on monday. Driving along about 45 miles an hour and lost power and huge cloud of smoke. Engine still running but any attempt to accelerate and it falls on it's face. Smoke out the taipipe all the time. After about 12 dealer excuses they say it needs a new short block. The wife drives it all the time so it doesn't get babied and it doesn't get the snot run out of it either.

I have a fleeting issue that of course only happens on rare occasions. I have a 2011 Elantra Limited. I drive it pretty easy. On three different occasions, when I really had to get on it to get into traffic, I have left a huge plume of smoke. From what I can tell it's darker in color, but it's been usually evening so I can't really tell. If I punch it again, it's fine. I have mentioned to the dealer each time and they say nothing shows amiss.

V8, approx. 12 K miles. Noticed lately that after the car sits overnight or maybe 2 days overnight, that when I start the car in the morning, there is significant smoke, actually a cloud. Value seals? How do I get VW to fix this problem? I am thinking about bringing a picture to the dealer when I start the car?

I have a 2000 E350 15 passenger Ford Van with 125,000 miles on it. I am burning a quart every 500 miles. The van produces a cloud of black smoke occasionally when I start it. Maybe once every 10 starts or so. It seems to be more prevalent when the van is parked with the engine downhill. About a year ago, I switched to high mileage oil. Could this be part of the problem? Or is there anything other than a rebuilt engine that will work?

This S10 has 4 wheel drive and the V6 engine and has 88,000 miles on it. Just about everything except the engine has been replaced because it was a work and plow car and took a beating. It is a great plow car, by the way. Recently a cloud of smoke comes out of the exhaust when you start the engine that has been sitting overnight. Mechanic says it is just old, but someone said that replacing the umbrella seals might do the trick. Stopped at my local auto parts store and they had never heard of umbrella seals.

I just noticed a burnt smell in the trunk of my 2013 Elantra Limited with 4,000 miles. You can't smell it inside the car. Called the dealer and was told, "Oh, don't worry, that's the burn-in smell", it will go away in a few weeks".

On cold start or when the cars been cool down for a hour or so, a huge cloud of smoke will come out. it smells plastic burn than a rich gas smell.
So far this is what i did, a oil change, add a no smoke oil treatment, replaced with an oem pcv valve (this fix my rx300 smoking issue years ago)
Video 1, Friday at 3pm. the temperature is ~60 degrees, less smoke after a pcv changed
Video 2, Friday after noon at 6p.m. ~50 degrees
Video 3, Next day 10 a.m. ~48 degrees
In person it looks white smoke, but the camera captures it more blue smoke. I have been constantly monitoring my levels and oil and coolants are just normal.

I have a 2004 Camry that I purchased used 8/2006 with 20,400 miles on it. It now has 83,000 miles on it. I’ve changed the oil and filter every 3,000 miles, and I’ve never had to add oil between changes. I’ve also replaced the antifreeze on time, using 5 yr/150,000 mile antifreeze. The only time I’ve had to add antifreeze was 4/23/13, to top off the overflow reservoir. Saturday I did my annual tune-up (plugs, air filter and fuel injector cleaner added to the gas). Plugs looked normal. Last week the car sat for several days, no issue on start-up.
Yesterday afternoon I started the car after it sat for two days. A huge amount of white smoke came out of the exhaust. It ran fine. I mentioned this to my wife, she said that about two weeks ago she saw a lot of black smoke (she thinks black) when she started the car and that it ran rough for about the first 4 miles and then started running ok. It has the 2AZFE engine, and I’ve read a TSB (TSB 1507) “It has been reported that stripped head bolt threads have been found on some of these engines during tear down. When the two rear head bolts lose their clamping ability they allow coolant to seep out at the rear of the cylinder head.” Could that be the problem?

About a 2 weeks ago I took the 2011 in to Hyundai to get the oil changed. (For the record I brought my own oil and Bosch oil filter). Anyhow, yesterday, noticed a nice pool of oil under the car after the first stop on errands. Looked underneath, and sho' nuff, there was a good little stream of oil. Made a bee line to the same dealership to drop it off. On the way we could smell burning oil and it was running like crap.
The service dept is open on Sunday so they called to tell me it was just the filter, he said probably a "burr" ?? and it can happen. My questions are Why did it take two weeks to start and should I be worried more damage happened? Supposed to pick it up tomorrow so trying to be prepared.

I have 2011 Elantra at ~20,000 mile, and strange things started happening since last year...and it kinda blew up today.
My dashboard has been flickering randomly for a while, as in everything goes dark and turns up again in the middle of driving.
And today it turned off and turned on (as it usually does), and the dashboard seemed broken; speedometer stuck at 0 mph, rpm meter stuck at 0, all warning lights turned on, gas meter going up and down and stuff.
Fortunately enough I was close to home so I drove it back home, and my gear shift was stuck at neutral (I could switch b/w N and D).
So I took out the shift lock release? thing and managed to put the gear to P and pull my key out. I stepped out of my car and I smelled something burning...not a very good sign. What should I do? Well I think I need to take it to dealership tomorrow but I'm not sure if it'll be safe to drive...

I'm going to take my Elantra in to get it checked. My Elantra is a 2013, got it in March. Over the last few weeks, I would say, on 4 days or so there has been a STRONG exhaust smell. No smoke, nothing else but a smell. If I'm pulling into the garage with no idling, just pull in and park, I get out and the smell in the garage is very strong. I have to leave the garage open for at least an hour if not more to air it out. The cab ends up having a light smell inside the next day still.
If I'm parking outside when I get out I can still smell it, but not quite as strong, because I'm not in an enclosed area. I don't think it's an exhaust manifold leak, because I don't hear the popping. My best guess is it would be in the tail pipe area pre-catalytic converter, or in the catalytic converter if it is in fact an exhaust leak.

While driving my 2011 Elantra a few minutes ago I just heard a moderate noise much like I had just driven over an empty pop can. Then white/ grey smoke started pouring out of my exhaust to the point I couldn't see the cars behind me. Just had 15000 mile maintenance about two weeks ago. My hubby has a lot of knowledge regarding older vehicles but says he's never seen anything like it before!

My Elantra is at 14k miles and it has happened twice now that the pipe has released white/grayish smoke when accelerating abruptly (pretty much forcing the engine) on the highway above 60mph. I can see in my mirror that it leaves a pretty big smoke screen behind me.
I took it for an inspection after the first time it happened and the mechanic said it might have just been steam and that I should not worry about it. Since my 15k maintenance check is coming up, I will ask that they actually check on it.
I'm also curious to know if this could cause me to get a ticket? I'm thinking I could get pulled over for "imparing the vision of drivers behind me and making it dangerous for them", or something like that.
