Week old Summit. I noticed that sometimes when I stop at like a redlight I get diesel exhaust coming through the air vents. Doesn't happen while moving. Dealer is telling me "that's normal" and to set the climate control on recirculation and not fresh air. Doesn't sound normal to me as I shouldn't be getting pre-cat exhaust through the vents....

I have had my Limited 4x4 EcoDiesel for exactly one year today, and have noticed that whenever I am at a stop light or sign with an accompanying tail wind, I get the diesel exhaust smell in the cabin.

There was a thread about this several months ago, and it has to do with how strong the vent fans are that draw fresh air into the cabin. They are so strong that even in a no wind condition, if someone is smoking outside the vehicle, the fans will draw the odor into the cabin and you will smell it despite the cabin air filter.

At 2,600 miles, I've never noticed any odors in my Overland, just the sweet smell of the great leather interior. My friends are learning a thing or two about modern Diesel engines. No odors with just a slight clatter during initial acceration and no noise at cruise. Auto Diesels have come a long way.

2500 miles and it has an extremely strong exhaust smell at least twice per week. So strong that I've had to drive with the windows down while raining. The vehicle also has no power at that time. It barely responds to throttle input and the MPG plummets. Dealer initally said put AC in recirc. Crazy. Had the latest TSB applied due to CEL. Was told that may solve the problem since it may be caused by excessive fuel being injected. 5 miles from dealer the CEL was back on. Been waiting 2 weeks now for NOX sensors. This is the 6th time in the shop in less than 2500 miles. At this point I want my Hemi back

Are you sure its actually diesel exhaust you are smelling? I smell the oil smell all the time when stopped. The newer diesel oil they are using has a very strong, distinct smell. My 2012 Ram cummins used to smell like this too until I changed to Valvoline Diesel Oil. Just a thought.

I drive 60 miles round trip to work that is 50/50 highway speed/congestion. The smell is absolutely exhaust. It is episodic and always associated with a period of almost unsafe lack of power. If I were towing something at the time, I don't think it could even climb a small hill.

I just got it back. Took over a week to get a NOX sensor from Jeep. Only drove it a short time, but it performed better than at any time since I bought it. Good acceleration, responsive to the throttle. They did say they went through the exhaust and found some not completely tight bolts. That wouldn't surprise me since I had to pull over on the highway and tighten a bolt hanging out 3/4inch in one of the undercarriage covers with a whopping 45 miles on it. I did hear the lunch-time pot smoking guys filmed by the Detroit news station smoking joints then going back to the assembly line who were intitially fired at the GC plant were rehired. Maybe that's the group putting these bolts on after their lunch break

Good to hear. The reason I asked about driving habits is due to the DPF regen. Short trip only use will almost guarantee that it's trying to regen all the time. Your driving is well suited to proper DPF health.

In reference to your lose bolts, the guys that added an aftermarket DEF injector skid plate almost unanimously found lose skid plate bolts. I spent a good 30 minutes tightening bolts under mine. Those weed toking union guys don't have to do squat to keep a job. Pitiful.

Is this an issue on the jeeps as well aside from this cabin filter issue? And is it something that keeps recurring (eg during Regens etc)? Are these typically faint odors or really strong noxious ones? This has me nervous about ordering now.

Also saw this last night around the different smells; not sure if 100% relevant in the jeeps vs rams

I have personally had a few instances where I had to open the windows to get some fresh air in...at -15, you aren’t too happy about it! Other times, a faint smell of exhaust that just needs a cracking of window...To say it is wide spread, I would or could not say. I will be changing the air filter and see if this happens again.( Can't see how this is going to solve, mostly to mask, IMHO ) Mostly happened to me on longer trips or at a full stop after driving for a while... I can say that within 10K miles, must of happen a dozen times....lost count. I would like to see if others have truly encountered this as well...My dealer looked at me like I was from another planet when I first mentioned it to him....now, when I showed him the TSB this week, he chuckled and said, ok I'll order you a filter...

This happened to me as well in first 2000 miles about 4/5 times. Chrystler created a star case for it, but dealer unable to replicate the situation. I am currently at 10k miles and haven't really noticed the smell recently, but I am glad to see TSB.

I have a 2014 with about 18K miles. I don't know if it is exhaust or some other odor but at times it is bad enough to make my eyes burn. Due for an oil change in the next couple of hundred miles. Will have them change the filter and see if that makes a difference.

This happened to me over and over. Dealer could not replicate. That and the scr replacement my jeep was in the shop 47 days for non routine work in the first 7 months. Filed a lemon law suit and 5 months later got word Chrysler is buying back my jeep. Really like the truck when it ran well. Going to give the eco diesel another try but this time in a ram chassis.

I have a 2008 Diesel Jeep Grand Cherokee, purchased the vehicle used 6 months ago.
if the vehicle idles always, I am getting terrible exhaust fumes where carbon monoxide levels are
very high to set off a detector each time!
has anyone found common source or a fix to this dilemma ?
3 mechanics have not located issue source , now going to Speedy Muffler to give them a try

Hello, I have a 2014 jeep grand Cherokee Ecodiesel. It’s currently been in the shop a year. I’ve gone to pick it up 3 times, and each time something else new is wrong. Yesterday was the latest pickup attempt, I got in the jeep drove on my way home and on the freeway at my exit, about 4-5 miles from the dealership a very strong smell is coming into the cabin through the vents. I told them about it back in February on second pick up attempt. On yesterday a mechanic finally acknowledged smelling what he said was coolant/ antifreeze. I don’t think so, because I have migraines and have been having them for years, this smell gave me a migraine on yesterday. I think it’s exhaust, when they looked under the hood it was smoking and there was a PCV hose not connected. Very frustrating that 3 times now I’ve gone to pick up my car after a year and still not ready. I don’t trust it will ever be fixed!
