Professionals using Class 5-7 work trucks are finding increased reliability from their engine and fuel systems, according to a new survey from J.D. Power and Associates. However, when breakdowns occur, they are more prolonged than before.
Compared to other diesel emission controls, selective-catalytic reduction technology, which injects urea into the exhaust stream to neutralize tailpipe pollution, is preferred among these truck owners, the study notes. Overall satisfaction ranked at 760 points on a 1,000-point scale. With urea equipment factored in, satisfaction jumps to 778 points.
