This vehicle has had numerous electrical issue from the first few months of ownership. The trailer brake system failed and was replaced on october 2014. The vehicle has had many recalls that have been corrected by owner and service provider. The second summer of ownership the vehicle had radiator issues, and most recently electrical issues again and transmission issues. While driving the vehicle electrical dashboard goes into a flicker and shuts down.
Headlights on this truck have always been weak, distance is not lit up and in rainy weather on the highway is very poor even with fog lights on. The help from the fog lights is minimal. This is a known problem by the manufacturer and is repeated many many times on various GM related owner forums. This is a safety issue and needs to be addressed and corrected by the manufacturer.
