This truck has the same problems as the 2007 model. The ignition switch, parking brake, and fuel lines all have issues as similarly described for the 2007 model. The fuel lines actually broke through causing a leak of the diesel fuel. This happened after the vehicle was driven a short distance of 15 miles.
My abs brakes prevent my truck from stopping at slow speeds.
