While driving at highway speeds (70 mph+/-), my diesel powered vehicle 'derated' (I believe that is the term) for no apparent reason. An engine light came on related to a DEF system malfunction. I can provide the code later. My vehicle instantly went from 70 mph to 15 mph on a crowded interstate, on an inside lane. With some difficulty I managed to make across three lanes to the shoulder and turned off the vehicle. After a quick inspection, finding nothing obvious, I proceeded down the shoulder to a gas station. I tried to top off my DEF tank, but it was full. After an hour the engine light went off and the vehicle drove normal. So I'm back on the highway. I went another hour, the engine light came on and the vehicle derated at highway speed. Same white knuckle lane crossing. This time I went to a truck...
When this RV is driven in temperatures above 91 degrees it will suddenly and without warning have a major loss of power. Vehicle will not drive above 55 mph even though it was on cruise at 68 mph. Has been to over 6 Ford dealers in 3 years and no one can find the issue. very dangerous since it has to be on the road for this event to occur.
