Camry :: Strong Exhaust Type Smell In Cabin After Warm Up And Vents On
Oct 18, 2012
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.

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?

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?

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?

I have done some reading of past threads regarding both Gen 7 Camry with people having an issue with a strong smell coming from their vents after perhaps 1K miles or less on their vehicle. Looks like some people had it fixed (some fixing it by themselves) while others continued to experience the problem. Similar thread regarding Toyota Camry Hybrid but only brief thread. Then another thread regarding perhaps another smell like from plastics /battery (?) in Prius while I was on the Prius threads.
Has this problem been addressed/resolved either by Toyota or by owners who simply fixed it themselves? I also do not know if the Prius offensive odor (someone who was testing them noticed it while test driving) is a totally different thing (like I say someone said it was from plastics or battery itself, not sure.... )
These are things I never even thought of /considered when looking for a new vehicle, and never experienced in my older Camry.

I have a 2007 Hyundai Santa Fe with 83k on it. For some months now, I have always been smelling strong fuel scent in the cabin. I took it to the workshop and was told it's my fuel canister so i handed money to the Mechanic to buy one to replace it. He called back to tell me he cannot get one to but can work on it by blocking the pipes or lines. I am not that convinced because i know the canister is there for a purpose so if he goes ahead to block the pipe or whatever, then it means something else can go wrong in the interim; but I'm in a quandary now and want that fuel scent to stop.

Yesterday afternoon, after a 90 minutes stop and go commute, a strong gas smell developed in the cabin of my 2009 LS460. The factory call-back service was performed on the car few months ago.
During yesterday's long commute, the LS460 passenger side wheels run over some garbage on the high way at high speed, and after that I can hear some noise from passenger side, sounds like a flag's flopping sound.
Other than that, recent incidents that I can think of that might be related are:
1. All 8 control arms of front wheels replaced about 3 weeks ago
2. Have been using Sam's Club premium 93 gas for the past 4 weeks

Mk7 GTI, currently at 5k miles but strong mildew smell coming from the vents.. I know the cabin air filters will last at least 15-20k miles.
I read before that the condensation hoses were sometimes installed incorrectly leading to run off inside the cabin. Can that be it?

Has encountered a strong odor of washer fluid when using it on your windows. I was driving to work this morning through a snow storm and needed to use my washer fluid for the first time. As soon as I turned it on the entire cabin was filled with that smell. Could this be a leak?I thought it was all confined within the engine compartment so not sure why I smell it immediately upon using.

I have had my Prius for a few weeks now and have noticed a very strong smell of petrol when I have the vents open to heat the car (without AC). It seems to only happen when the fan is on and vents open. What could cause this and should I be concerned?

My father in-law gave us a 1996 explorer AWD with a 5.0 for my son who is 16. A couple of weeks later he's out learning with my wife and a very strong electrical smell took over the cabin. They came right home and when I got in I found all of the gauges not working. The instrument lights work, blinkers work, but all gauges do nothing. Pulled cluster and wires look O.K. behind it from what I can see. They saw no smoke, just smell, fuses look O.K.. What could cook on this vehicle that would wipe out just the gauges?

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.

CEL came on. No performance issues or noises coming from the car this time around. I did notice that after parking and killing engine, there is a faint exhaust-type smell though. I took the car to my local Advance Auto Parts and had them hook the car up to their computer for a diagnostic. Two codes came up.
1: P0431, warm-up catalyst efficiency bank 2 below threshold pending
2: P0431, warm-up catalyst efficiency bank 2 below threshold confirmed
The AAP employee didn't have anything to add to the code readouts. I'm concerned that this is a catalytic converter issue, and if that's the case, a repair would likely cost more than I'm willing to put into the car at this point. It has just over 125K miles on it.

When starting the RX, I smell something I would describe as "burning insulation". It happens only first 10-20 seconds after the air comes out from the vents, and then the smell disappears. The smell is stronger after prolonged parking. It is the strongest in the morning and less noticeable after I start the RX 2-3 more times ( I usually make 6-8 short trips during the day). The smell was very strong when I started the RX first time after it was parked for one week (while we went on vacation).
There are no warning lights, and the vehicle runs just fine. I pulled out the carbon cabin filter (changed about 3 mo ago) - it did not smell and was very clean still. I am hesitant to go to the dealer-afraid they will rip apart the dash, which they probably will not be able to put back together without having rattles and noises after.
The smell comes from the inside - there is no smell under the hood after I start the RX.

2000 Nissan Sentra with 105,000 miles. Runs great. All scheduled maintenance from the beginning. Grandma owned until I got a hold of it 2 years ago.
The beginning...
The car has had a slight exhaust-type smell for about a month. I thought it was either an exhaust leak or a small oil leak. I overlooked this as it was running great and I only drive to and from work at a total of 5 miles/day. I was going to be driving it about 20 miles so I figured I should just double check the oil.
Before my drive, I checked the oil and the dipstick said I had absolutely no oil. Backstory: I got my oil changed about 2 months ago and they broke the dipstick. They replaced it with a new one. I drove a few blocks to get oil. I purchased 2 quarts filled it up. I drove off and about a half a block later it started smoking bad. White smoke canvassing the whole street.
I turned around and went back to the auto parts store. I had a guy come out and look at it and he was baffled. The only thing he though was that it had run completely dry and it need more oil. We put 2 more quarts of oil in it (4 now) and it did not register at all on the dip-stick. A small oil leak was discovered coming from the head gasket (that was the smell). Also, there was no milkiness under the oil cap indicating
I decided to drive it back to work to leave it overnight. It smoked like hell and I made it about 4 blocks before it died. I pushed it the rest of the way and it stayed overnight.
The next day, I spoke to a mechanic friend. The only thing he could think of was that the dipstick was not the right size and it wasn’t reading any oil. The oil I put in was extra and the car was burning it off. He suggested I drain out all the oil and put 4 quarts in.
I drained all the oil but only 4 quarts came out. I added 3 quarts of oil and checked it again. Not it was reading about 10 times more oil than what I was supposed to have.
My mechanic friend said to start it up and the oil level should go down. I did start it up and the oil level did go down but it was reading about 5 times more oil than it should have. That is where I am at at this point. Hopefully it isn't a blown head gasket or piston.

I've noticed a strange problem that makes it next to impossible for me to use his truck unless the vents are off or I have both windows all the way down with it on. It smells like it has a fuel leak of some sort and in the cab of the truck it smells bad while driving and gets worse when sitting still, to me it smells like gas and when I open the hood on his truck after idling about 5 minutes or so I can smell it in there so i know its somewhere under the hood but for the life of me I can't see anywhere where its leaking or anything like that but I can smell it all darn day. His truck is an 05 F-150 with a 5.4 and I'd like to figure this out before it becomes a real big problem. I've worked with fuel injected cars and trucks before but I have little knowledge of the mod engines at all. And he is still driving it like that and I just wanna make sure it either is not gas or is just something simple I'm overlooking.

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

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 got my 2000 Passat back from the body shop. I rear-ended an SUV about a month ago and had my hood, front bumper, left headlight, A/C compressor, and radiator replaced.
HOWEVER, now when I let 'fresh air' into the cabin, I smell a strong exhaust smell. When I push the 'recycle air' button, the smell goes away. This leads me to think that somehow my exhaust pipe was cracked/damaged in the collision and is now spewing exhaust gas into the engine compartment - and thus when I allow fresh air (front the engine compartment) into the cabin...I am getting toxic exhaust blown in my face!
Where should I look for signs of an exhaust leak and is there an easy 'trick' to find the leak?

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.
