I bought an 08 chevy duramax a month or so ago. Love the truck, pulls great but the thing keeps throwin' a "clean exhaust filter see owners manual now" message. I googled it and it says to drive at highway speeds for 15-20 minutes. Three times it comes on and then throws a check engine light and goes into reduced power mode. 2 of the 3 times I had been on the highway for about 3 hours. It seems like this is common on these trucks but was curious if anybody had any experience with it?

The quick answer on that is that the dpf is choking up but one of the sensors mounted in or around it is faulty and it cant initiate a regen.
