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.
View 5 RepliesJust got my ark grip exhaust and noticed it being a little too loud in the cabin. I thought they were suppose to be pretty quiet inside...
View 8 RepliesWhen 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.
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?
From time to time, i get some exhaust smoke smell in the car, when driving slow or standing in a queue.
90% of the time everything it's perfect, but at a sudden moment, the rpm is rising with 50 or so, the instant consumption rises from let's say 1.4l/h to 1.8-2.0l/h when in gear and standing, i get a small vibration and then the exhaust smell appears.
If i'm closing the recirculation, then no more smell.
After 15-20 min, everything get back as it use to be, 1.4l/h consumption, no vibrations no smells no nothing.
This i think happens when the dpf is cleaning and i cought with vcds of a friend when it happened and the exhaust temp was 350 celsius or something. Usually is 200 degrees celsius, so it is a dpf regeneration. Also the car is running smoother after this.
Still..the smoke smell... it's annoying and quite strong. There is no sign of smoke from the exhaust pipes, flexible pipe or whatever. There is no sign at all anywhere.
I have a small theory but i don't know from where to start. Usually the catalyst temp is 200 degrees. When it's 350, it expanding more, or at least the cracks are expanding and smoke+smell is from there...but there is no sign anywhere.
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?
View 2 RepliesGas / Exhaust fume smell ... in the cabin? I've been noticing I smell like I've been in an old school muscle car running straight pipes every time I take the car out. More of an exhaust fume smell but sometimes the fresh gas smell is very strong.
View 12 RepliesAfter 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.
'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?
View 3 RepliesMechanics are stumped. 3 months ago, during a 4WD commute through the snow, I started noticing what at the time smelled like bus exhaust coming into the cabin. My SES lights comes on for 2-3 days, then off for 2-3 days. Codes say MAP sensor and low coolant coolant.level. When the SUV warms up fully, you can smell the odor strongly under the hood, inside the cabin while sitting at a stop light, and inside with the Heat or AC on. Mechanics had the car for days, replacing cam and Map sensors. There is no evidence of exhaust leaks or coolant on the engine. Level of coolant has been dropping slowly in the reservoir.
View 9 RepliesNot 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 have an '08 Grand Cherokee Laredo, 3.7L V6 with 74,000 miles on it. Recently the exhaust/muffler have been getting loud, and during my state inspection the guy said it would probably need a new muffler/pipe in the next few months. That was about a month ago. Since then there has been an on-and-off horrible plastic/chemical smell in the cabin some of the time. My wife drives it about an hour to work each way, and she says sometimes it gets so bad she has to open the windows (in 20 degree temps....) or she gets a headache. She describes it as a "formaldehyde smell" and says it tastes kind of sweet. To me it's more like a burnt plastic/chemical type odor. I checked all underneath but saw no plastic bags or anything else odd. Nothing unusual under the hood. No visible smoke. I have an appointment in two days to have the exhaust fixed. My question is - is there any way this weird smell could be exhaust related? I am hoping so, because otherwise it's a total mystery. It's definitely not an "exhaust" smell as I know it.
View 11 RepliesI 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.
I own a 2004 Ford Taurus (3.0L V6, OHV (12), non-flex fuel) registering a P0420 engine code. If I can smell exhaust fumes in the cabin, can I assume there is a leak in the catalytic converter system, or could the O2 sensors be the issue (or could it be the catalytic converter itself...)?
View 3 RepliesI 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.
View 4 Replies2003 6L 250 SD. Always smells of exhaust on the cabin. If there is snow it gets much worse.
View 2 RepliesI have been smelling raw exhaust in the cab, especially when the weather is colder and when standing still.
I took it to the dealer and in the process of fixing minor coolant and oil leaks on the turbo, they located a small exhaust leak with visible soot on the back side of the turbo.
They tell me that there is no way to repair it and that only Ford can rebuild or repair these turbos.

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.
View 14 RepliesI have a11 isf with 38k on it. The other day the check engine and traction control light came on along with a weird Oder in the cabin. secondly I was short the quarts of oil.... I see no leaks.

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.
I bought a used a 2008 LS600hL and noticed that when I run the fresh air setting with the AC off (like in winter) I get a musty smell in the cabin. I had Stevens Creek Lexus (Santa Clara Ca.) check it out and they tried to put a fragrance on it but that wore off after a few days. I have no problems with the water drainage (they checked) but wonder if I need to pull the AC coils and replace or something like that.
