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?
View 3 RepliesI 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.
View 229 RepliesI took my rear springs off for some cleaning and lubing because they were making squeaking noise on hard acceleration, but I forgot to note which direction the springs should point...
I kinda remember the top and bottom. If I got this right, the end with a smaller loop is on the bottom.
Is there any difference between left and right springs? Also, the spring mounting pads is not symmetrical. Which way are they suppose to face? Does it matter?
Ok so the wife and I were heading home, she was in her 2.0t sedan, I was in my 3.6 4motion wagon. I got stuck behind a slow driver on the highway (doing 50 in a 70 mph zone) so I get in the passing lane and I floor it to pass him. When I get home, my wife tells me she saw a good amount of black/blue smoke coming out my tail pipes when I went to pass the other driver. This is on a engine with 2400 miles.
I take a look, and the chrome exhaust tips I had installed not long ago are now all black, covered in a oily thick residue. These same exhaust tips were on my previous 07 3.6 4motion wagon for 10k miles and was still shiny when I took them off. but after about 1k miles on the 08, they are now all black. I check the oil and it still reads full.
So what could this black smoke and this oily residue on the exhaust tips be caused by? should I be concerned? Engine runs fine with the exception of sometimes stalling when trying to start it after a short stop. (VAG-COM doesn't show any error codes logged.
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 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?
I recently purchased a 2011 F350 chassis cab with no bed installed. Have a few questions regarding the exhaust system. When I inspected and drove it noticed some black smoke when under hard acceleration, nothing major though. Other that that the truck drove great. Have not got the truck home yet, a friend is going to pick it up and deliver it in a few days. Based on the visible smoke I was suspicious of the exhaust system but I have no knowledge of what the system is suppose to look like. My experience with diesels and for that matter gas engines is mostly from the days of mechanical fuel injected diesels (70's era farm tractors mostly) and carberated gas engines.
My friend stopped by a local Ford dealer and crawled around under a new 2015 Chassis cab to look and compare to this 2011. It appears that the SCR and DPF are not installed on this truck. Where they would normally be is a section of pipe with a section about 2 feet long that is 6 or 8 inches in diameter. Looking at some threads on this site I'm guessing this is a muffler that has been added since the truck is not loud. There is no DEF tank and all the wiring for sensors that would be attached to the exhaust system appear to be tied off to the frame and not connected to anything. The dealer didn't know the history beyond he purchased it on an auto auction and he installed a new rear end in it. Car Fax shows nothing of concern.
My question is should I now be concerned since have determined much of the exhaust system has been removed? I've read some threads and it appears that the only way this can be done and have the engine run well without any codes etc is if the removal is done with some sort of tune. Is there any way to determine who has done the tune? Will it be an issue when take to a Ford dealer for service?
I know if wanted to put the system back to stock would be large dollars, as long as the system runs well and is reliable I will be happy. The anticipated use of the truck will be to pull gooseneck trailer and will probably not see more than 1000 miles a year towing and 5 to 10k total in a year. I drive with a very light foot seldom ever pressing any vehicle to its limits. If still have the truck in 10 years when retire or at least cut back on my work then it may see more miles.
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!
I have a 2001 7.3 with 243k. I think the injectors are shot but other people including a local mechanic say it's not the injectors. What the truck does is smoke white. Sometimes little puffs when accelerating. Sometimes clouds that make the people behind you drop back a 100 feet. I have a ts6 on the truck and that alone with the 243k miles is enough to think its bad injectors. It smoke white. The exhaust is moist to the touch with soot built up like crazy. It doesn't really smell sweet and it's not really blue at all. It's getting horrible mpg. And lacks power. I don't have a high enough psi gauge to test compression. All arrows pointing to injectors?
View 8 RepliesAs 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 RepliesOur 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.
View 76 RepliesMy 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.
View 10 RepliesOk, 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.
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...
View 10 RepliesWhile 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!
View 13 RepliesWell this makes the 3rd time I am going to have to take my car into the dealer because of the right rear brakes. I had a guy pull up to me yesterday and tell me that I had smoke coming out of my right rear wheel, I pulled over nd the rotor had a slight blue glow to it and the caliper was smoking. This is starting to get old, I wonder when the lemon law kicks in on something like this?
View 8 RepliesOur ABS light, anti-skid light, and engine light are on. The light came on when 3 year old son hit it. It just never went off. Dealership hooked it up to diagnostics and said we needed to spend almost 500 on a new ABS system. ALSO, at the same time, the car now sounds like its working very hard to accelerate. The rpm's go up, but there is no additional power. Is this connected to the ABS problem, or is this a transmission problem? Took it to a mechanic and he didn't check the transmission. After talking to him, he said it could be the transmission.
View 19 RepliesSo for reason irrelevant, at about 500 miles on the odometer, I drove the Prius quite hard the past couple of days. In retrospect, a poor decision as I am now all kinds of concerned as to what kind of damage I may have done. I know break-in is said to be 600 miles so I was below that. I'll describe my 'hard' driving as heavy acceleration, often pedal to the floor, a few hard stops and umm excessive speed (we'll leave that up to interpretation). So I'm just stressing about it now.
View 15 RepliesMy car has the wavy acceleration feel and sometimes hesitates a bit. It is way worse when the a/c is on. I wonder if this is a octane or sparkplug issue. On my old cruze 1.4t the gap was wrong from the factory. It came with all four gapped under .022 but the manual called for .028. Everyone gapped to .035 with great results. Not checked the sparkplugs yet?
View 12 RepliesFor the last few weeks (about a month) I have been experiencing a clunking noise/ knock on acceleration coming from either in front of my feet or below my feet (drivers side) ONLY on acceleration and only then from a full stop. I can also feel the clunk as well which leads me to believe it is a transmission mount.....maybe an engine mount. I am taking her to the dealer after work today. we had some very cold weather and I was hoping it was just ice but yesterday and today were well above zero and it is still there and it is EVERY time I accelerate. Which is a somewhat good thing since I will be able to replicate the problem for Hyundai.....
View 17 RepliesI am starting to have an issue with my 2012 auto transmission Elantra that just passed 100k miles. When under mild acceleration, as when gently leaving a red light accelerating to 45 mph, I can feel a distinct chugging as if a cylinder is randomly mis-firing once or twice a second. This is never felt during coasting with no power applied. It is also not apparent during full throttle or aggressive acceleration. Only during casual daily-type driving. Now I have had other cars in the past that once in a while would throw a CEL code if a cylinder mis-fired, but I have no Check Engine Light on. This leads me to doubt a mis-firing plug. What could be the cause of this?
Other possibilities would be perhaps the auto transmission is somehow momentarily interrupting power to cause the mis-firing effect??? Is that possible? Perhaps the fuel pump is going bad and getting intermittent? But then why is all good during full throttle?
