I've heard that many have had emissions and therefore performance issues with their 2007-2011 era CTD. What about the current 2012 models? After driving both a Hemi 2500 and a CTD 2500, I love the way the diesel drives. But I'm trying to figure out if these emissions issues have been cleared up, or if I'd be buying myself a problem truck. After doing some research I see the software was tweaked in the new trucks, so I'm wondering if some of the recent issues have been fixed. According to one article I read, that's the case. I'd love to hear from some current owners about how it's going so far.
