There are several issues with the truck, the worst being misfire issues while driving at highway speeds. Several times now I have been on the interstate at speeds and the truck will all of a sudden lose speed and shutter. The engine light will blink, and this will happen for a couple miles and then it gs back to normal. If you pull the codes on the truck, you get P0300, P0301, and P0305. This is in the dealership again now. The previous two times the dealership has done nothing because they can not duplicate the issue, but they do pull the codes.
