Elantra MD (2010-15) :: Huge Plume Of Smoke On Acceleration
Feb 9, 2012
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.

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.

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.

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?

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.

Originally, the inciting event was a plume of smoke coming from under my hood. I had the car towed and they said my radiator blew up and did the repair. A week later, I was smelling what I thought was radiator fluid. I took it back and they said I had three major oil leaks. My wife didn't understand why they did spot the leaks just a week earlier, if they were that major? All that said, I had been going there for awhile, so I trusted them. They fixed, or they said they fixed, all three leaks but when they returned the car, it would kind of rattle intermittently whenever the car was stopped but running.
I had no such problem before bring it in for the other issues. They kept it for another few days, almost a month in total with all the repairs and they said they got it to where it was barely noticeable. Well now, just two weeks late, it has been getting worse and worse, the rattling of the car when the car is stopped. And tonight, all of my warning lights suddenly came on- engine warning, brakes, everything all at once. I spent two and half grand with this shop and they returned it with a problem it didn't even have before. It needs timing belt, that was the next thing to get repaired.

I drive a 2010 Golf GTI 6 dsg and its has some performance problems - it is the not responsive huge delay in acceleration sometimes doesn't even push out the turbo, just gives me a high raw with low output. Even at robots its take a while to respond after I have put my foot down? I have taken it back to the dealership and they tell me everything is fine - they changed the DV valves and upgraded the software but the wheels are more powerfull and the output is still low.

It is 10 degrees now (-12 C). I softly engaged the clutch and noticed the car wasn't moving. I tapped on the gas lightly and the car was trying to move, but couldn't. I finally gave it a lot of gas and there was a huge POP sound. When I park my car, I leave e-brake engaged. Are brakes suppose to stick that bad in cold weather? The Pop sounded like a .45 Pistol!!

I have a 2013 GT and my wife a 2011 sedan.
[URL] .....
I've looked it up and didn't find any reports of it happening to the GT. (I admit I didn't look too hard!)
It happened to my wife's 2011 sedan when accelerating onto the highway. Just as described in the "massive smoke" thread. I couldn't see the car following behind me, the smoke was that bad. No exaggerating!
-- no check engine light
-- no change in temp
-- car drove fine immediately afterward (we babied it till we got home)
-- oil level and colour OK
-- coolant OK (overflow between lines)
-- next day car felt fine during full-throttle 80-120 km/h acceleration.
-- mentioned it at dealership, with service adviser, service manager and mechanic all listening to the story. They were stumped but offered to look at it. Adviser suggested a "BG Products fuel induction" treatment, which I'm assuming is bogus. (Haven't had a chance to check into it)
My web searching suggests the car had a "carbon blowout" cuz my wife rarely drives on the highway. I've heard of this but always thought it was just a myth. I mean, seriously, have you ever actually seen a car throw up a James Bond smokescreen just cuz it hadn't been driven hard? I'll betcha five bucks that if I took my mom's babied 1997 Camry onto the highway and floored it, nothing would happen. So what's up with the Elantra?

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.

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?

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?

2 days ago, and again twice today, I have had an issue when I need to change lanes and speed up, but when I hit the gas pedal (not flooring it, but significant pressure) I have had the car jerk 3 times while the rpm needle goes up to 6. Then the rpm drops to 2, the acceleration finally kicks in, and a huge puff of grey smoke makes the cars behind me completely disappear.
I've read threads about the smoke with the acceleration, but no one mentioned the jerking and not wanting to actually accelerate at first.
There are 33,000 miles on my car.
I called the dealership and they said it only sounds like it's an issue that something in the engine needs to be cleaned out, and they want to charge me $200 if that's the case.
Should something need to be cleaned out at only 33,000 miles? (mind you I also just had the dealership tell me I didn't need my 30,000 mile tune up yet after doing an inspection).

I am writing about a 2007 Chevrolet Suburban and for the last few months, have noticed that the car is losing oil. I have to put in a quart of oil about every 3 weeks. I have brought it in to the mechanics and asked them to look for a leak and they can't find anything. They have changed the oil, replaced the evap hose, but the car is still losing oil. Just did a lot of driving this last weekend and the oil went all the way down, to the point of when I started it this morning, I got a huge amount of blue smoke out the back. When I took off the cap to add oil, I noticed this mustard yellow, foamy stuff on the lid. Never saw that before.

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?

Had a very strange thing happen today. The weather in the northeast here was just amazing the past two days. So I took a nice ride in the car up through Granville, NY and over the back roads to Vermont. The whole trip I am kinda hyper-mileing getting about 40 MPG (or better) the whole trip, on one long strait road with a mild declining grade I got over 60 MPG!! The whole trip I did 40 to 50 MPH, just taking my time, once or twice getting to 60 MPH, just so I didn't hold up traffic on a couple main roads.
Ok, so I just get southbound on Rt 30 north of Manchester, VT. I am heading south. The road is posted at 50 MPH. I am doing about 45 MPH and come on a vintage car doing about 40 MPH, no problem, I am really not in a rush, I leave him lots of room. Just enjoying the nice day at a leisurely pace. But the guy in the vintage car pulls over to let me pass. Ok, so I go around him and continue on at about 45 MPG..
I quickly come up on a white Subaru I think it is, looks to be 8 or 10 years old, now this guy is slowing down to 35 to 40 MPH.. there is a big long strait away, and no on coming traffic, and this guy seems to not even be able to hold 40 MPH on this road posted for 50 MPH.. so I decide to pass him. So I step on the gas and pull out into the oncoming lane. Next think I know I see white smoke EVERYWHERE behind the car!!! And it appears to be coming from MY car!!!
Now in full panic mode I am trying to sense any odd noises or vibrations from my car, fully expecting my dash board to light up like a Christmas tree any second!! My car proceeds down the road, I back off the gas as much as I can while still trying to pass the car I was passing, get back in my lane and get ready to find a place I can pull the car off the road.
After several hundred more feet the smoke that appears to be coming from the back of my car, or under it, tapers off, I keep watching my dash board for any engine lights that might come on.. car seems to be running smoothly, but I now VERY nervous about driving it..
No lights came on. No odd engine or car sounds or vibrations. I am stumped where all the smoke came from!! It was NOT just a little, it was like a James Bond car setting off a smoke bomb so the cars behind couldn't see! I mean, I could not see anything behind me, in two lanes, for several seconds. I was like "WOW!!" As I looked in my mirrors!
My 2011 Elantra has about 12,000 miles now. Never had any engine problems at all.
I have four theories of what the cause might have been:
1. When I hit the gas to pass that car high pressure in the engine somewhere forced some oil into the exhaust system somehow, and it had to burn off.
2. Just as I was about to pass that car I think I turned on the AC. Maybe as the AC belt was about to engage the high engine RPM caused the belt to slip and burn, and smoke, until I backed off the gas and it caught on the pulley properly.
3. Maybe the transmission dropped one too many gears, causing the tires to slip on the pavement when I hit the gas and I did a "burn out", "smoking the tires".
4. Maybe the smoke came from the Subaru. But replaying the whole thing in my head I know I saw smoke out MY back window when I was in the oncoming lane. I find it hard to believe the smoke did NOT come from MY car. Especially given it started exactly the time I hit the gas to pass him.
I am tending to think it was theory #1 above. But I just don't know. Still love my Elantra, And the car seemed fine after that for the 60 or so mile ride home. But I would love to know the real source of the smoke I saw!

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?

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.

While accelerating moderately into traffic one day the engine seemed to quit and the engine light came on, soon after the engine came back to life the engine light went off and clouds of smoke came pouring out of the tail pipe. Light blue not quite white though. Engine was running fine. After letting it cool down a couple hours I restarted and the same thing started. Called the dealership and they took me in the next morning. Mechanic says he has seen this before and it sounds like a bad ground somewhere. I am no rocket scientist but if there is that much smoke pouring out of the tailpipe I would tend to believe that something in the engine( head gasket/cracked head) would be a more reasonable assumption. Having said that, the dealer has had the car for 2 days now and they still have not told me what the problem is! Only 40 k on it, certified pre owned...

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!
