Hello all,
I purchased a new 2014 Patriot Latitude about four weeks ago. It now has 1300 miles on it. Periodically when I accelerate I smell a rotten egg kind of sulfur smell. Sometimes the smell is slight, other times strong. This happens for example when I go up a hill, pull away from a traffic light on a highway, etc. The vehicle is a little underpowered so I find sometimes you have to give it a little more gas in certain situations. But I dont mean pushing the pedal to the floor.
I took the Jeep back to the dealer's service department. They told me if the engine light is not on, there is nothing can do. They said it wont even show any codes, and the fuel mixture is controlled by the computer. My personal mechanic confirmed this. The service tech told me the catalytic converter needs to break in and I should give it about 3000 miles to do that. My mechanic that he has never heard of a catalytic converter having to break in on a new vehicle. Im 59 years old and have owned a few new vehicles in my time , and I never had an issue like this.
I called Jeep/Chrysler and they told me that they have heard of the smell issues on other vehicles but not on the Patriot. They contacted the dealer, and now the dealer wants me to bring it in so they can test drive it. I dont see what a test drive will do. A smell is a smell. But I will bring it in anyway.
Anyone have any ideas about this smell issue? I can try changing the brand of gas I guess. But I always have used this brand in my other vehicles that I have owned. And I live in New Jersey if that is needed for any info. Thanks.
 
one possible cause of sulfur is bad cat,
never heard of a cat needing to be broken in,
nonetheless Cat should have 8 yr/80k mile warranty on it. so shouldnt be any harm in waiting the 3k miles like dealer said(should have record of dealer visit, problem you brought it in for and dealer recomendation printed)
another possibility if car has been sitting is just water/mold in the vents,
can try spraying a can of lysol into exterior vent, with interior fan on,
 
I would keep a close eye on the exhaust system for any visible smoke or areas of strong odor. Keep track of the times it does it and what the Jeep was doing at the time. Hopefully it's just something small burning off from the initial build. (excess grease or something in a place it doesn't belong.) Best of luck I hope it's nothing major.

No smoke. But I did get out of the vehicle after it made the smell. It is coming from the exhaust
 
I periodically get a cat/sulfur wiff in my 2011.

always when I have a bit of a load onboard and am going up a fairly long hill.

I think it just takes the engine management stuff a bit to figure out what is going on and its just the cat doing what it is supposed to do...cleaning up unburned fuel rather than dumping it out the back pipe. If you are 58 then you also remember the first introduction of cat vehicles, I certainly remember that smell before they got them dialed in.
 
We would get this smell when we'd put new exhaust headers on our street cars.There is a special coating on the exhaust that burns off when the exhaust is new.Smell should go away after a while after the exhaust has been hot.
