Mine has it as well, very faint and it takes a good 3 to 4 hour run for it to rear it's smelly head! I've had her into the dealership a couple of times and they can't figure it out. Would be nice if Chrysler would at least throw a TSB number on this so we could point the dealers in the right direction. I'm very lucky though that mine is very faint. I've popped off the rad cap and had a whiff and it's not what it should be but it's not bad enough to make you think something is very off. The first time I got a whiff of it was a week into ownership and I just figured it was the factory rubber floor mats?
