Jeep - Grandcherokee :: Exhaust Getting Loud - Plastic / Chemical Smell In Cabin
Jan 30, 2014
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.

I get more or less constant wine-like odor in the salon, as well as intermittent burning match (sulphur?) one. These seem to be seeping from the outside, through the ventilation system. The car has a new radiator, and the heater core, there are no apparent coolant leaks.

The sound is random, inside the cabin, probably comes from in front of the driver. Lasts for a few seconds but goes on repeatedly. I found that when I apply the brakes, even a gently tap, the sound goes away, but will return.

I have a distinct coolant smell inside my Jeep (2009, 60k miles). I popped the hood and couldn't spot any leaks nor was there any fluid underneath the vehicle. I took it into a mechanic and they smelled the same thing and put the coolant system under pressure (as well as doing a visual inspection), and could not find any leaks nor was there any evidence of fluid by the vents. They also noted that my coolant levels were still full and I had not added anything to the car. The current theory is a pinhole leak in the heater core (the smell is definitely worse after the car has been driven a bit).
I have had one suggestion to add Bar's Stop Leak to the radiator, but the mechanic said this was a Bad Idea (his argument being that since there was no visible leak in the system it would likely just gum things up). Since the vehicle seems to be otherwise operating fine, I'm hesitant to replace the heater core, but there's a good chance it's still under warranty, so I could go that route.
So, could it be something other than the heater core? Should I have that replaced or would the Stop Leak be a good idea?

I have a '98 Jeep Grand Cherokee 4w with a 5.2l, it has approx 145,000 miles. It leaks a little oil and when i recently checked it (level was good), it smelled of gas. It starts easy and runs great with no smoke and no knocking when shut down. I've read it could be anything from rings to a stuck injector. I drive it on short trips now, only occasionally going out of town. It is due for an oil change but I would like to have a solution before driving it more or getting the oil change.

Went over a bump on the highway the other day and heard a loud noice as if I was dragging something under the car. I checked but nothing was there. It reminded me of putting a baseball card in your spokes of your bike when you were a kid. It happened twice and the weird thing is that if I put it into reverse and drive about 10ft The problem went away. But something still seems loose and it sounds like it will happen again. I was googling this and it seems like the noise was around where the center differential or drive shaft?

I own a rear-wheel-drive 1999 Jeep Grand Cherokee. I recently had both rear axle seals and bearings replaced. At the same time I had the mechanic check U-joints, shocks, etc. The noise from the failing bearings is gone, but now I have a loud "howl" that gets louder the more I accelerate. If I take my foot off the accelerator, the sound is gone. As soon as I accelerate, the sound returns. It is barely noticeable at speeds less than 35 mph, but the howl gets increasingly louder as the speed increases.
I returned to the mechanic the same day I picked up the Jeep. We went on a road test and I was given a story about gears in the differential and that despite the noise everything was mechanically sound. Even though the sound was not present before the seals and bearings were replaced, the mechanic assured me that nothing is wrong. This howling is giving me a headache!

After battling the general nitwit public earlier. I was on my way home and as I neared my house, a party bus was blocking the road. Well, I got angry, shifted to reverse, revved the engine while letting out the clutch to back up and take a different route. Then this horrible burning electric/plastic smell inundated the inside of my R. I knew I rode that clutch while backing up. My question is did I do noticeable damage my clutch, or is it one of those: it'll be fine just don't do it again thing?

I have an issue with my 2006 Jeep Grand Cherokee v8 Laredo that has been bothering me for a little over a year now. When the temperature gets warm out (over 80) and I am traveling on the interstate up a long hill (65-70 mph, towards the end of my commute so about 30 miles in or about 30 minutes) my engine randomly begins to sound like I am in the wrong gear (RPMs do not change but engine sounds like I just changed to second) and I loose quite a bit of torque. I can maintain my speed but my engine sound horrible. After about 10 minutes of this my engine goes back to normal and I can accelerate without issue. Then randomly it goes back to being loud with low torque. To add to the the fun, if this happens at any time during the day, the next day when I start my Jeep the issue resurfaces and I have no torque for about 10 minutes (5 miles) then all is well for the rest of my commute (40 miles downhill). I had a diagnostic scan done and they found nothing wrong and I also just got both of my exhaust manifolds replaces but the issue continues.

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?

Gas / 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.

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.

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.

'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?

Mechanics 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.

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?
