Saturn - Ion - Smells :: Exhaust Fumes In Cabin
Jan 17, 2011
I have been getting exhaust in my car cabin since last fall. It is worst when I first start up the engine. Once I get driving, it's not so bad. Switching off the heat or recirculating the air does nothing to change things. I used a CO detector in the cabin and the alarm didn't go off, but it still worries me that I might be breathing in carbon monoxide. And none of the shops have been able to diagnose it, let alone fix it. The first shop installed a new 'flex pipe'. The dealer thinks it's coming from a gasket near the flex pipe. The exhaust manifold is not cracked. A muffler shop said there was no leak. Is it possible that exhaust is somehow getting mixed into the air via a faulty valve or vent?

After I start the car, warm up a bit then drive, there are exhaust fumes that get into the cabin as you can smell them.
It's happening more often now. I have spoken to my Phaeton tech who said that the car has a sensor that goes off and shuts down external air if it notices exhaust uses getting in.
I have been hearing a little bit of road noise on the driver side so I'm thinking some fumes are coming in from the door seal (although it looks fine).
Sometimes it's bad enough that you have to open the windows or you will feel sick. It passes within 5 minutes or so and the car is fine after that. It only happens right after ignition for a few minutes.

About two years ago, I noticed the smell of exhaust fumes in the cabin of my 2000 Honda Civic any time the vents were set to pull air from outside the cabin. Switching the vents to recirculate would prevent the fumes. Looking under the hood, I found the exhaust manifold was cracked, so I replaced it along with the catalyic converter (actually one piece in this model) and two O2 sensors. Since the replacement, the problem with exhaust fumes remains. I have asked my mechanic to look at this a couple of times, and he could not find the cause. What to try next to diagnose the problem. We use the car frequently, and just have to leave the vents set on recirculate. This becomes an issue on rainy, humid days when recirculate causes the windows to fog.

I have been having an issue with exhaust fumes in my 13 GT (16,000 miles on it). I am positive its from the exhaust. Its definitely the "rotten egg" smell, not raw gasoline. I don't hear any leaks though.
It only happens when going up a hill when the engine is under more load than usual or under heavy acceleration. I am going to call the dealer about it and have them look at it.

Newly acquired 2002 Accord.
At idle and while at a stop, the cabin receives a heavy dose of exhaust fumes (nope, not from the auto in front of me - I'm often alone at stop lights/signs)... what is the most likely culprit?
This did not seem to occur until AFTER I had the timing belt (package) replaced...coincidence

I have a 2000 Ford Focus ZTS with about 135,000 miles on it with a fume problem. Once it's warm, I'm noticing what smells like exhaust fumes in the cabin when stopped or at low speed (not at highway speed.) It runs perfectly otherwise. I took it in a few months ago (before I noticed the correlation with engine temp), and the mechanic could not replicate the problem, and he said there was no exhaust leak, I now suspect this is because he only tested it cold.

I have a question with aftermarket exhaust (particularly JoeZ and Borla) I was wondering after you installed the exhaust do you now get increased exhaust fume smells in the cabin when the windows or moonroof is open? When I had my 350(F-sport exhaust) I couldn't cruise with the moonroof open without filling the cabin up with fumes.

My car smells like burnt fumes when I drive; especially in the cabin! At first it occasionally smelt this way, only when I stepped on it. Now its constant. The valve cover gasket has been changed, and it still smells! The next step is to delete the PCV. These fumes are making me sick; rolling down your windows does not work....

Have a 2002 Chrysler 300m with a 3.5 v6eng. Problem is It takes 5 to 10 secs to start my car in the morning, It doesn't start like should, It doesn't show up on the computer. I think they call this long cranking. Had plugs put in at 50,000 miles because of a bad plug, coil is fine and fuel pump is also. Once car starts it smells like gas fumes in the air. At loss as to what the problem is. I don't want to do a lot of lets try this and try that, as this could cost me a lot of money .I have talked to the mechanic and there not sure, along with a dealership. They see dollar signs.

I have a 1996 Volvo 960 station wagon which I love dearly. It's been a wonderful car, however something new has occurred that has me quite concerned. Whenever I turn on the heater, I smell gas fumes. This doesn't occur when the A/C is working or when I turn the temperature dial beyond the numbers to the red mark. I understand this is a different heat source than the regular heater. When I took my car in to the dealer for its 150,000 miles checkup I told them about this problem. They experienced it, but couldn't find the source of the challenge. They want me to bring it in again and keep it overnight so they have a lot of time to decipher the source of the problem.

Well I started smelling Gas fumes in the cabin of my 11 GLS. The smell was intermittent for about a month now. Then last weekend it started getting bad. I found it only smelled when pulling fresh air through the HVAC, so it had to be under the hood. Pulled the engine cover to find the foam backing was soaked with gas. Started the car and could see the Hard fuel line dripping.
I saw from other post on the forum that this tube has one time use fitting on both ends and that a special tool is needed to torque the fittings. Dropped it off at the dealer yesterday and they are replacing the line today.
I tell you all this because the Dealer said that their records show my car had the short block replaced at 24000 miles. When replaced they probably didn't torque the line correctly causing it to leak.
The question I have is, Should I be more or less worried about the bottom end of this engine now that I know it has been replaced? The car has 44000 miles on it now.

My mom has a 2000 Passat 1.8T Sedan. For the last six months the car has the distinct smell of engine fumes in the cabin. The smell becomes more prevalent whenever the fan is running (A/C or not). She has constantly been back and forth to the dealer but to no avail. The smell is there are idle or just driving around and requires a window to be opened for fear of passing out.

I am getting fumes in my 1990 4Runner SR5 6 cyl. I believe them to be exhaust or oil burning, not fuel. The condition does NOT exist when the windows are closed or when the fresh air vent is open or closed (recirculate).The fumes exist in the cab only when I open a window (driver side), and is mitigated some when I open the fresh air vent. This may mean that the leak is not coming through the ventilation system. What could be causing this?My mechanic says it is worn valve cover gaskets, dripping oil onto exhaust system and finding its way into the cab, it does leak oil. This may be true, but how are the fumes getting into the cabin the first place? The fumes came on suddenly, after a rear window repair at the shop - unrelated?The vehicle has been inspected by a muffler shop, no issues with the exhaust or manifold system.The fumes are inscrutable, not strong enough to easily detect, but persistent exposure gives me a headache and dizzy feeling, and then I get polluted enough, that I cannot really smell it anymore, hard to trouble shoot.Interior smells of exhaust, even when parked.?

Our prius is 13 yrs old and the fan of the heat/ac broke. We had it replaced at the dealer and also had them replace the cabin airfilter. Since then, whenever we use the fan (heat or AC), we've been getting fumes in the car, a gas smell (even when there are no cars in front of us, so it's not from other cars). We brought it back to the dealer twice and they have not fixed it. They found a hole in the exhaust system and replaced the muffler etc. My questions:
1) Is there a way to measure the air quality in the cabin and find out what fumes are coming in and how dangerous they are?
2) What could it be and how can we finally get it fixed.

Been this way for awhile. I can smell gas with my windows down. It's very potent. Almost everyone that rides in my car can smell it. What could this be?

I have a 2010 with 5k miles - bought <4 mos.
Last week, I started noticing a petroleum smell in the cabin. I've also had trouble with the inside windshield. When I tried it wipe it, it just smeared. Finally, I used some cleanser and it's clear. It took several applications to work.
I read in the Gen II forums about a loose oil filter cap. I checked mine today. I was able to turn it about 1/2 inch. Now, I'm getting headaches after I drive for more than 15 minutes or so. I've tried switching the circulation but I can't tell which way is better.

First Hyundai my 2014 Elantra SE. Love it to death. Used this forum to start doing my own car maintenance,
Changed the oil (using Hyundai OEM filter).
Cleaned the throttle body to stop the rough idle.
Chirpy fan getting replaced with new blower motor tonight so while I am in there:
And the reason for my post: Had a smell coming through the vents that just smells like rotten leaves. Changed the cabin air filter. Smell still there.
Where does the cabin air filter air intake go? I want to make sure there are no obstructions or smell inducing things living in this intake.
I guess my question is..Where does the air come in to the cabin from and where best can I make sure its unobstructed?

A little background on my Prius, I have an 08 that has around 179k miles on it and have never had any major mechanical problem. I have always kept up with routine maintenance. I use Synthetic oil and change it about every 6500 miles.
So, two weeks ago, it was time to change the spark plugs again. Carefully, I took out the old spark plugs and installed the new spark plugs. On the second spark plug wire and spark plug, I noticed a little bit of oil, so I wiped it off with a shop towel, installed the new plug, and kept going.
Interestingly enough, now I have a problem where when I first start my car (and only when I first start it) and I just have the interior fan running (not with the A/C on) I get some serious extreme exhaust fumes through my A/C vents and that wasn't happening before I changed the spark plugs.
Now my first thought was, "Shoot, what the hell did I do to my car?!"
Here's the weird part, once the ICE has warmed up and shut off for regular "ready" mode, I don't smell it ever again even if the ICE activates as I'm driving. Note that at this point, I haven't made any changes to what fan speed or setting the climate is on.
As soon as I turn my car back off, then back on again by pushing the power button, out comes the awful exhaust fumes again.
So, here's where the testing stage comes into play. I have tried everything I can think of. Yesterday, my father take the air box off and we made sure all of the hoses were attached and the recirculation hose didn't have a clamp. We replaced the clamp and resecured all of the hoses in the engine thinking that there might of been a loose hose with the exhaust recirculation.

I've had my car for 6 months and have noticed that when I start my car with the vent on blowing air I can smell exhaust fumes. It doesn't seem to happen every time and if I start the car with the air off I don't smell anything. I can turn the air on after ten minutes of driving and the smell is there at first then seems to go away, either that or I get used to the smell. My closest dealership is 60 miles away

I recently bought a 2003 Hyundai Accent 1.6L DOHC manual transmission hatchback with 124000 miles. So far the work I have done in the car include replacing front bank 02 sensor, new flex pipe, exhaust manifold replaced with a used OEM part. Everything is going great with the car except that the check engine light is on with the P0442 and I occasionally smell gas or exhaust fumes (not sure) while driving and it goes away. My combined mpg is only about 23mpg.
I replaced the gas cap with a brand new OEM part then cleared the CEL. However, after driving 90 miles, it went back on so I brought it to my mechanic who recommended a smoke test. After the smoke test, he said the charcoal canister and the diagnostic module needs to be replaced. Is it worth replacing to fix the CEL code and if the code is related to me smelling fumes inside the car while driving. Also, I would like to know if there might be another problem causing this code instead of the charcoal canister or the diagnostic module.
