Have followed a number of threads on this forum over the months regarding frequent exhaust particulate filter regenerations. Had my first regeneration this morning. Started up the truck to go to the gym and EVIC notification said something like "Exhaust Filter 80% Full, Regeneration Underway." (Not the exact words, but close.) So, took a 20-mile detour on the highway while the regeneration completed before going to the gym. I have 29,560 miles on the truck (it's one year anniversary is next Tuesday, June 30) and this is its first regeneration. Guessing this is primarily because most of my miles are long distance trips at speeds of 55-80 mph.
