During the epa mandated exhaust regeneration cycle the vehicle begins to shudder uncontrollably along with power loss. this behavior began at around 5,500 miles and now does it at least every other exhaust regeneration. it happens on multiple lane country roads and city roads at around 50 to 60 miles per hour. it seems more specific to the regeneration cycle than any other driving condition or input. temperature is between 40 and 70 degrees outside so far. each time it happens is worse than the last. the experience is scary and could be very dangerous. i no longer let my wife drive this vehicle for fear that it may shudder her off the highway.
Exhaust region caused extreme rough running engine and loss of power when towing up hill and passing a semi. this caused the semi to almost hit the back of my trailer. this continues to occur with every exhaust regeneration on the 6.7 powerstroke diesel.
