While the vehicle was in motion on a city street, the fuel management system failed almost causing me to be in an accident. The engine sounded like it was blowing up with metal on metal sounds, loss of control and power. I had my vehicle transported to an authorized mechanic and he determined the fuel management system had failed and the engine would have to be rebuilt. I spent over $3000 to have it repaired and it still leaks oil and has issues with providing correct engine power and control. It is not safe nor dependable.

My 2000 GMC pick up truck has a loud engine noise referred to as piston slap. The noise has been present since I purchased the vehicle. I have since found that this is a common defect with some gm engines. The dealer states that there is nothing wrong with my vehicle but many web sites describe it as a manufacturing & design defect. I believe this causes decreased performance and increased fuel consumption.
