As far as Dodge/Chrysler working out any bugs with the DPF/EGR/software/etc in the years to come, that's provided they're still in business after Nardelli & Co. get done with their handiwork.
I could echo the sentiments of "the engine is great, the truck is junk" when it comes to the '05 Jeep CRD I have. Great little engine, 185 HP with a Euro spec tune out of a 2. 8 L four banger, but DC bean counters really cut corners on the support systems - crappy torque converter, vacuum fuel system, crappy EGR setup (some people have replaced EIGHT EGR valves inside of two years), a fuel heater that stays on constantly and has a habit of melting it's casing and has actually caught a couple vehicles on fire, a closed CCV setup that seems designed to spray the maximum amount of oil into your intake, an air intake that sucked up every piece of dirt on the road and turn the air filter sopping wet after driving in a hard rain, etc, etc - it's like they wrapped a diamond in used toilet paper.
And the only real fix we got from DC was a series of computer flashes to detune the engine to try and make then hold together until out of warranty. As soon as DC made the decision to quit marketing them, tech support became nonexistent.
3 grand in aftermarket fixes later - different air intake, CCV filter, Suncoast TC, Stanadyne fuel filter, lift pump and fuel cooler, high flow muffler, aftermarket tune, etc - this little beast will flat out kick rear. Had DC not been so determined to cut corners on production costs, they could have had a world class diesel vehicle that would be selling faster than they could build them.
I think there's one real reason why DC's fixation on cost-cutting in the past few years didn't turn the Dodge CTD into a piece of junk like the Liberty CRD - CUMMINS!!!! Being an independent company and determined to protect their reputation, DC knew full well that Cummins could pull the plug if they felt that DC was surrounding their engines with cheap crap that would cause them to fail or make them look bad by association. OTOH, VM Motori was mainly owned by DC, and had to salute and carry on smartly no matter what DC did with their engines.
And having worked for a DC affiliate company for the past 10 years, I can tell you that the cost-cutting push came mainly from the "D" part of "DC".
