just got my GC and have put 350 miles on it. Has anyone else noticed on occasion while at a very low speed starting out that you can sometimes smell diesel gas odor for a few seconds in the cab with the windows up? i have never owned a diesel, but my friend with a Ford says that shouldn't happen. it is definitely diesel gas that i am smelling.

noticed it on mine on the way home from the dealership. They had to add def to the tank as it was reading 3/4 full at delivery. Thought maybe they overfilled? But continued to smell intermittently since then. Have 325 miles on it now.
Almost smelled like something burning off the exhaust, as I picked up on the smell as I got out and walked around the vehicle, but its not there all the time?!

I'm a tic over 400 miles now. I noticed some odd odors, like petroleum odors so to speak, after parking it in the garage. Most of it I chalked up to exhaust burning off surface oils etc. Haven't had a noticeable diesel fuel odor in the cabin. Maybe it's off-gassing from the capless filler? I have to say, I don't like that arrangement. The fuel door doesn't fit tight to the gasket on mine, I noticed water in the area after washing it. I riged a spray can top over it to cover it - don't want any more water to get in the system than supposed happens from just diesel fuel alone.

I'm experiencing a similar issue with a burning smell inside the cabin. I'm pretty certain it is not diesel. It has happened twice with both times being in stop and go traffic. I'm just over 600 miles now and hope this is just new products breaking in. Other than that its a pretty sweet ride. Averaging 26.5 mpg with a good mix of hwy & city.

I noticed the filler door and water as well. Mine is poorly aligned. Spray paint can lid? I'll try that.
To be specific, I used the cap from a can of hornet spray. A regular paint can top is a bit too small. The hornet spray can top fits great, fits snug over the rubber collar that surrounds the filler neck. I cut the plastic "DIESEL" ring that was in place around the filler and put it on the top. I figure, should anyone else ever drive it be it family, friend or the dealer, if they have to physically remove a cap that says DIESEL on it (x2) the likelihood of someone putting gas in it should be pretty low.

I was pulling a small trailer, 5' x 8' with almost no load and going up our gravel driveway I smelled exhaust in the cab... sort of like burned cooking oil. I can't imagine the exhaust came forward into the fresh air intake at the front window, but maybe the wind was doing that. Next time I'm going slow I'll press the recirc air button for the 3 minutes it stays on. I walked around the Jeep and the odor was also near exhaust so assume it is the DEX fluid reaction in the exhaust. I noted when I topped off with 1/2 tank of diesel fuel that it contained "not more than 5% biofuel". I'll avoid that Shell station. Diesel in Oregon is $3.79 or $3.99.

I read that Jeep is looking into it, lots of owners have mentioned it but after around 300 miles it has gone away. Probably just burning some sort of coating on a part.

I believe I discovered the issue. While sitting in traffic in Grants Pass, OR this weekend, a woman in the car next to us was smoking with her window partly down. Her cig exhaust was drawn into our air intake system almost immediately. Smelled like she was sitting in the backseat smoking a full pack. So now in traffic I always press the Recirc button. But that only lasts for about 2 or 3 minutes in winter conditions in AUTO setting.

Love the idea of using a cap for the filler, great idea, some might even consider this recycling or reuse.
Just wondering aren't all these Jeep GC supposed to come with cabin filters? Would upgrading to a charcoal filter help fix the problem?
I have the same issue with around 1500 km on the odometer, had everything from the buring smell to the diesel odour.

Glad the cap idea is working out. I'm happy it works, even if it seems like it shouldn't be necessary on a new vehicle of this value. It is what it is, washed all the salt off it today from our Thanksgiving trip and sure enough, water got in the filler area again, but not in the filler hole thanks to the cap.

I can't say I've had much issue with the weird odors. I may be more tolerant, or might not have a good sniffer. I have noticed though that the air handling system does seem to bring in outside odors quite rapidly and quite well, for better or worse. Maybe that is all it is? A charcoal cabin filter would be nice - may have to look into that.

Just got my grand last night and have not done this yet. On my ram diesel,also has the cap less fill, put a fernco cap on. Can get it in the plumbing section as the hardware store. Needed in 1 1/2 fernco and it fits nice, and can trim if needed.

I'm preparing to purchase a new Overland but I'm still deciding on diesel or gas. I noticed the exhaust smell while on a test drive. The sales person could not give any explanation for it. Of course he was also not aware that DEF fluid was required for the vehicle. I don't think this is exclusively a Jeep problem however and it could potentially be a continual issue. I am a paramedic and all out new ambulances use a DEF system. At least once per shift or every other shift, average of 150-200 miles per shift, that smell comes into the cab. I recognized it instantly when I drove the Jeep. It is a bit of an annoyance but usually only lasts a few minutes. To date our mechanics have not been able to isolate it or present any solutions. It does seem to be an inherent issue of DEF equipped diesel vehicles.

Hey all. New to the forum. I recently purchased 2013 RAM 2500 Cummins Diesel (my first diesel) and like the idea of diesel in a cherokee so I've been watching this forum. Anyway, although the diesels in the Cherokee and Ram are different, that are still diesels and need to regen the diesel particulate filter every so often. Around 3000 miles I believe I went through a regen and smelled the odor of diesel fuel for a little while. I now have 6000 miles on my truck and haven't had another incident. Normally, standing outside my truck you can't tell its a diesel by the smell of the exhaust. I'll repost if it happens again but thought this might put some minds at ease.

I purchased my Jeep Grand Cherokee Diesel Dec. 3, 2013 and noticed the smell soon after. Dealer couldn't find an issue. Finally on my first Trip, to Atlanta, approx. 600 miles on it , the DEF LOW WARNING came on. I stopped at a dealer in route to check and they found the DEF Dozier Control Valve leaking. It's in the shop now waiting on parts. The smell could have been the Def spraying on the exhaust.

Hi All, I just bought my Limited diesel and it has a little under 200 miles on it. I have noticed this smell too, mostly after hard accelerations. I noticed it during the test drive and asked the dealer about it, they said "new car burnoff" as well. My brother has a wrangler that's obviously not diesel and he said that his was smelly for about the first week or so he had it. I'm hoping this is a burnoff thing. Sounds like from a lot of you that is what it is. I think I might try the recirculation trick for the next several hundred miles and see what that does.

***Update: I drove home with it recirculating and it definitely helped but every so often the climate control would turn it off and the smell would come right back. I really hope this is a temporary thing as the smell gives me a headache over the course of my normal commute.

We now have about 1800 miles on our 2014 GC Overland and it took far more than 300 miles to stop that smell.
I called service to make certain this was normal.
Now I do not smell anything.

We pulled our 5,000 pound travel trailer / RV to test the new jeep...worked like a charm. But now trading the trailer in for a 28', dry weight 5200 pound unit next weekend.
Looking forward to seeing the MPG results. Local commuting is 26 MPG on 4x4 version.
