I have noticed on several instances while traveling on the freeway between 60-70 mph when the truck goes into regen mode I get a loud valve clatter and a loss of engine power. This could be very dangerous.
- Friendswood, TX, USA
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.

When the vehicle is performing a regeneration, and you are going up an incline, the engine can shake and valve knocking can be violent accompanied by a loss of speed and power. The first violent incident that happened was going up a narrow mountain road and fortunately no one was injured. The vehicle has been taken to the Ford dealership and contacted Ford corporate multiple times and they are unable to correct the issue and unwilling to spend enough time to witness the issue themselves. The loss of power occurs unexpectedly and could cause someone to lose power while merging onto a highway which is unsafe or cause the vehicle behind you to rear end your vehicle when the power loss occurs going up hill.

At times while driving, the vehicle will begin to shake and lose power. The issue occurs during different driving conditions and has happened while merging on the highway. Ford service department was told there wouldn't be a fix until 3/1/2016. It's an issue with the PCM.

When the cleaning exhaust filter message comes on, the truck runs extremely rough and the engine gets a violent shake with loss of power. It also has a loud pinging sound. This lasts for about two minutes. The first occurrence was when merging on to the freeway with the sudden loss of power. I have had the truck in two dealers. Both state this is not normal but Ford has indicated it is and will not authorize work until something breaks. The odd part is that the computer reads that all is ok. The dealer states all is not ok but the issue is something the computer isn't tracking"?"

The contact owns a 2015 Ford F-250. While driving at various speeds, the vehicle shook violently without warning. The vehicle was taken to a dealer, where it was diagnosed that the fourth and fifth cylinders were misfiring and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 3,200.
