I am glad that I came across the thread as I am victim of this stinking issue too. I have 3,700 miles on my 2013 Longhorn Laramie 5.7L 8 Speed. What a joke! This is my 5th Dodge RAM - 2001, 2003, 2006, 2010 and now this Lemon 2013. I logged an issue with my local dealer - first the service manager said he could not smell it. Then he said well I might have caught a wiff of it when we were standing in front of it but I can't smell it inside the cab. I had them have a mechanic pop the hood and open the radiator cap - WOW! the smell almost made me puke right there. I opened a case with Chrysler customer care - again what a JOKE- the case manager does nothing. Acts like I am making this issue up and tells me that they are not aware of this issue. Now that I have to turn the heat on in the truck it is getting worse. I am going to stop driving the truck but still make the payment. From what I can see this smelly issue was posted on the internet as far back as May 2013. I bought my truck in August. I find it hard to believe that Chrysler doesn't know about this smelly issue.
