The people who were having problems with the 07-09 6.7l Cummins usually had a plugged particulate filter. This was caused by never getting the truck into a regeneration cycle. These people never got into the regeneration cycle because they didn't use the truck ... too much start and stop in town grocery runs and not enough towing going on.

Or being used all day every day, including towing about 30% of the time. Still was a fuel sucking POS (both of them). Yes, they were nearly always in regen because our service area was primarily in town. But I don't think that was the reason for premature water pump failures, turbo failures, and an Aisin transmission failure at 60,000 miles.

You mentioned Aisin failure - that tranny was only offered on the cab & chassis up until 2013 so you must be referring to some type of fleet use I would imagine. I've seen plenty of issues with the engine but I wouldn't go as far as saying that all of them or even most of them had water pump and turbo failures.
