I'm selling my Chevy Duramax diesel, love the truck its just too much for what I need, and I'm just starting to look for a Jeep diesel. I'm wondering if I should steer clear of the '14's and spend a bit more on a '15 or '16? I know that sometimes the worst part of a vehicle gets the most attention and blown out of proportion. Is the trouble that the 14's had significant and if so were they worked out in 15 and 16? Or, is it generally the case that once the Cat converter is sorted out the 14's are good to go. I'd appreciate some insight...thanks.
