Since purchasing my truck, there has been an ongoing problem with it simply shutting down mid motion, causing brake and steering failure. Three months after purchase this problem was directly responsible for an accident (on an icy roadway) in nh. I have taken the truck to countless garages in an attempt to remedy the problem, to no avail. I continue hearing from several mechanics; "fuel injection problem - a bad year for GMC . . . " the problem was only occasional at the start, and tolerable, but has gotten progressively worse - to the point where I no longer am comfortable taking it out of the yard - yet I continue paying off a loan for a truck I cannot trust. Again, I have dealt with three different garages (diesel), with competent mechanics, and after having various parts replaced - eventually find myself with the same problem occurring, again and again.
