I am thinking of buying one I need to know of any big issues that may change my mind  

Haven't heard anything negative about the new 6.7s. All the new diesels have a lot of emissions stuff on them, but that's unavoidable now. You're going to have that with all of them.  

i havent heard much of bad things from either dodge or chevy buy ford on the other had has a fuel hog on their hands now.  

i own a 07.5 havnt had any problems a few computer issues one was a temp sensor, i cant remember the other, they have had a few issues with the dpf program but they just reprogram the computer and all is good i havnt had dpf issues myself but a few friends of mine have with their 08s come to find out they idle theirs allot witch causes soot build up therefore they have probs ,  

I have a 2008 4x4 2500 series Dodge Ram Diesel with 13000 miles that I would love to get rid of.  It has been in the shop a total of six times for emmissions related issues.  Now I am having a Turbo and fuel pressure issue. I suggest you wait until 2010 before you buy a Dodge Diesel. What really sucks is that I traded in a 2002 4x4 3500 that I wasn't having any problems with I just wanted another truck and got a piece of crap.  

I too have a 08, 2500, been in shop 3 times with computer, emission's problems, looking to get rid of it also. Looking at NC lemon laws now  

I have had a couple.  Check engine light comming on and then going off.  Problem fixed.  No power and drinking the fuel.  I took it to the dealer, dealer cleaned the turbo and exhaust also reflashed ECM.   I now get 17mpg   in town 15mpg pulling trailer.  I just want to get rid of DPF and improve MPG and Performance.  

i own a 2008 dodge diesel 3500 4x2. I have 9000 miles on this truck and have had it in the shop 4 times. twice for a clogged particulate matter filter and twice for a clogged turbo booster. i was told this was because of extended idle time. although the computer reports 14% idle time. I am ready to check the lemon law in Ark  

I would not reccommend that anyone buy the 6.7 Dodge diesel pick up, to many problems with smog/particulate filter, keeps clogging up. My 2008 dodge 3500 has been cleaned 3 times & replaced 4 times. Truck has been in the dealeership 7 times for this problem. if anyone know of a good fix for this problem please let me know.My email is almonsm10@yahoo.com
Thanks  

If you don't yet have wide availability of ULSD in your area, then I wouldn't get an '08 or '09 diesel of any kind. The old 500 ppm diesel is poison to the new DPFs. ULSD is 15 ppm, and that's what these engines were designed to run on. ULSD isn't going to be mandated coast-to-coast 'til 2010. There are still some holdouts that are still selling 500 ppm diesel.
