Elantra MD (2010-15) :: Intermittent Strong Exhaust Smell
Jul 4, 2013
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.

There is no noise that would indicate a hole in the muffler, just the exhaust smell. I'm wondering if the catalytic converter is going out? If it is the catalytic converter, will it strand me on the highway eventually?

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.

For the last few months, I've had an annoying problem with my 2003 Liberty. If I'm driving the car with the blower on (i.e. when it's cold out), whenever I stop the car and am idling, I get a very strong exhaust smell coming in through the vents. If I turn the fan off, the smell goes away. At first I figured it was due to being behind other vehicles, but now I've noticed that it does it all the time, even when there's nobody else around.
I brought the jeep into a shop a couple of weeks ago to deal with a separate CEL issue (evap leak - fixed by replacing gas cap) and I asked the mechanic to look for an exhaust leak. He said he didn't see any readily apparent problems with the exhaust line.
I'd like to deal with this because it's not very pleasant to inhale exhaust fumes through the vents. I intend to take it back in - but is there anything I can tell him (i.e. like, a particular part of the exhaust system to inspect more carefully) that will solve the problem?

The exhaust from my caprice if thick and white. And there's a strong carbon smell. Could this mean my cat converter is bad?

Not long ago my wife said the air recirc doesn't work any more on our '04 V8 and I had to admit that I agreed. After a little investigative driving, I noted that heavy acceleration (or uphill climb) causes V8 to tick (can hear it reflecting on passing walls, for instance) and strong smell of exhaust in cabin.
I thought it might be a manifold/exhaust system leak causing the noise and the exhaust smell. Seems to be only when driving aggressively or climbing. Soonest the local dealer can see it is 7/21 (16 days from now). You think it safe to drive?

I purchased a 2011 Chevrolet Impala last year with 14,000. When the car reach 26,000 I begin to smell a very strong sulfur smell coming from the exhaust. I took the car to the local Chevrolet dealer and was told that the particles in the catalytic converter begin to break up at about 26,000 mile and the result is a sulfur smell.
I didn't believe that all Impalas had this problem. So I took it to the Chevrolet dealer in the next town where I personally know and trust the maintenance chief. He put his two best men on the car and could not find anything wrong. I was told to try another gas station which I did but it did not work. I now have 31,000 miles on the car and the smell is very strong coming into the passenger compartment when stopped.

I just had a blown motor swapped with a used engine with around 50,000 on it in my 2002 Toyota Camry LE 4 cyl.
After driving the car enough to warm up I turned the vent on and in comes a fairly strong exhaust type smell.
I have driven the car for a little over an hour since the motor swap.
The car is driving fine with plenty of power and no sputtering or rough idling.
I just called my mechanic and he seems to think it is due to the oil that is present on/around the motor/exhaust from the swap that is burning off.

My car was running rough, with white smoke and strong gas smell coming from exhaust. It died out on me a few times as if it was not getting enough acceleration. Well, I coded it and said misfire cylinder 3 and 4. I also tried to shut down 3 and 4, but did not shut down. I switched 3 and 4 with 1 and 2, still did not shut down cylinders 3 and 4. Engine coils are good, engine module was tested and passed twice. Ok, fuel injectors 3 and 4 were leaky and I changed them out. New spark plugs and boots. New oil and filter..(There was gas in my oil and oil in my air filter.) With the new parts....my car sounds soooo much better!!! still a little rough, does not bog down, but it still has the strong gas smell and white smoke from exhaust..(gas smell soo bad I had to open all doors to the garage!!) What else could be wrong?!?! I'm getting frustrated!! It also has NOT ever over heated, does not run high.

We've had a run of -20 to -40 weather here for the past few weeks.
A few weeks back I noticed that when I climbed into my truck after command-start warm up for 10 minutes, and I could smell strong exhaust.
I figured it was hopefully the wind, or an isolated event.
Over the past few weeks I've used my truck for 3-4 more around town runs and every time I warm it up I get the strong exhaust smell. It's that rich, eye watering, sickening exhaust smell. I also notice a small yellow frozen puddle under the exhaust tips that wasn't there before.
It's bad in the cab, but even walking around outside the truck and the smell is sickening. I actually just started the truck and I could actually smell the exhaust smell faintly, from inside my house! This has never before occurred. Prior to this, a person could hardly tell it was a diesel by the smell of the exhaust.
Once the truck is up to temperature the smell seems to disappear, or at least lessen.

Not at the exhaust, but from the engine compartment. Have to open the windows at a stoplight. Can also smell it when I walk past the parked truck. What's up?

1994 reg cab 4.ol 13ok.. my wife just got it, been doing some small things like replaced dome light, replaced cargo/third brake light, truck starts and seems to run ok. but i get a headache in it which i believe is carbon monoxide, has a leak or something? i text previous owner, he said he replaced 02 sensors, but didnt say if they were bosch or a good brand.. also trucks has a oil pressure and coolant temp gauge fitted on by the gear shift as the dash gauges for those functions are out. Does this mean the CTS may not be working and affecting fuel/air I do not know these trucks i only just found out what this strange silver looking thing was it is the IAC, I Believe, then there is this black plastic vacuum type cylinder by the passenger side firewall, what is that? and right against the drivers side fire wall is a small reservoir type thingy, is this something to do with ABS? i do have an ABS light on, was hoping it was the bulb out on the third brake light or something quirky like that no such luck its still on after starting engine. but i am concerned about this running rich/strong smell as we really cant take it far as is it, its dangerous, may have to get a smoke test? Just got the truck, trying to get caught up..

I'm getting a strong fuel smell inside my car typically after i fill the tank regardless of how much i fuel i put in. What could be causing this?

I have no problems pumping gas in, but the entire car cabin smells very strongly of gas after filling up. It seems to come from the area of the charcoal canister. No dripping of gas, no puddles... Did a smoke test, no leaks showed up anywhere (according to the mechanic). I do not want to start throwing parts at this to fix it - where should I start, and in what order should I throw parts? 2003 elantra GT sedan, 70k ....

'90 Maxima 256k.....recently I've noticed exhaust coming in through the vents when I have the AC on and have been idling or driving in slow traffic. I know I have a small exhaust manifold leak because I hear the clicking. The problem is this exhaust smell happens very intermittently. Usually on hot humid days when I have the AC on. I have tried to duplicate the issue to no avail. Sometimes I can sit in a parking lot at idle with the AC on for 30 minutes and I don't smell any exhaust (not even when I smell under the hood). How can this be? If it truly was an exhaust leak then it would leak all the time and I would smell it. Could my EGR valve be leaking? When the EGR valve is activated?

I have a 2010 Prius and it has developed a very strong mold smell/odor. It is strongest when the car has been sitting with the windows up. I have tried many of the tips in the forum regarding not using the recirc mode. I've clean the car inside and out, mats, carpeting, every compartment.
I have talked to the dealer parts counter and replaced the cabin air filter with the carbon filter and used the 2 can treatment that Toyota sells (one in the a/c drain x2 and the other in the air intake.). No joy.
I took it to the service department they did the same thing - again, no joy.
They have asked me to bring it back for, and I quote, "exploratory surgery." I asked if this the covered under the Toyota Certified Warranty. He could not confirm that it would be covered.

Our 2010 Ford Fusion Hybrid has been great and trouble free. Recently, however, we've noticed a strong smell,like fiberglass, come from the A/C when starting from a cold engine.

I have leased a new Hyundai Elantra Limited 2012. We have noticed a very strong odor in the trunk. We have removed all the trunk mats and spare tire insulation trying to air them out and the smell still persists. It smells like something is burning or has burnt near the wheel wells or the back fold down seats. How to get rid of it?

We have gotten a record breaking amount of snow this winter and it has been tough on the smaller vehicles. The last couple days my car has developed an odd issue. When I start the car and it is not warmed up as in there is only one bar on the engine temp meter, I put the car into reverse but don't take my foot off the brakes and the car starts to vibrate strongly. Once it's warmed up to a few bars it operates normally. I know the brakes have some ice on them too but that is a different matter, also there is snow/ice packed into the underside due to the amount of snow on the roads here.
Car is currently parked in my garage with the heater heater on so hopefully it can melt some of the junk from the underside by tomorrow.

For a couple months now, maybe longer, my 2010 Accent has developed a funny "rough sputter" I would call it at idle. It seems to be getting worse and worries me now. The RPMs fluctuate as it happens. The CEL has never come on throughout this. I'm not 100% sure it's not present when driving.
I did not replace the Fuel Filter at four years or the Fuel Air Filter at two years & four years. Could this be a Fuel Filter related problem?
I got out of my car today to listen to it and noticed the exhaust was intermittent along with hearing the car sputter.

I have a 2014 RX 350. I have noticed an intermittent issue with exhaust smells coming into the cabin when the car is on recirculate and I am at highway speed. It happens when I am first accelerating after I've entered the freeway. If I get the odor, I can make it go away by briefly hitting the recirc/fresh button to bring in fresh air for a few moments. This doesn't happen driving around town.
