I recently retired and have managed a fleet of trucks for years, about half of which were MaxxForce 7’s. We learned to have the particulate filter cleaned and serviced once a year by the local Navistar dealer which was about 25000-30000 miles for us. Granted that the Max Force emission system was a weak link but by keeping them cleaned, we had no more problems from them than we did the other trucks running Cummins. I think it cost us around $1000 to do the cleaning and service. If I wanted a Breeze, I wouldn’t be scared of the MF7, I would just have the particulate filter cleaned every 3-5 years.
