While Pulling 35' 5th Wheel down freeway, a message appeared in instrument panel telling me the fuel filter was at 0 percent and was going into low power mode. There happend to be an offramp there that I was able to get off the freeway. While making the turn on the offramp the truck died. I pulled over as far as i could whie coasting with no power steering or brakes, leaving truck & trailer partially blocking the offramp. Unable to start the vehicle, I Immediatly contacted Onstar and they dispatched the CHP & tow truck. When CHP arrived he asked when tow truck would be there. Without being able to confirm exactly, and due to safety concerns because of blocking the offramp, he called his own tow truck (Rons Towing) and forced me to move vehicle to safe location. The issue ended up being the injector fuel pump (CP4) that GM was well aware of going out and sending metal fragments throughout the fuel system. I've been told the pump was made in China and not to GM standards. The vehicle has been repaired, all work was covered under extended warrenty, This all could have been avoided if GM would have replaced the faulty fuel pump under recall. Had this happened 100 miles further on our trip we would have been going over Pacheco Pass in Calif. Could have been a total disaster had we been going down the other side with No Power Steering & No Power Brakes pulling a 12,000 lb Trailer in the Dark.

While driving at 45mph in the left lane of a major city thoroughfare the engine quit running, power steering and brakes did not work. The check engine light came on when the engine quit running. I was able to get the vehicle stopped but the engine would not start. The vehicle was towed to the dealership where I was told this issue was reported in Arkansas, Louisiana and Tennessee. The dealership reported that shards of metal were found in the fuel injector and the entire fuel system would have to be completely replaced. Additionally I was told the parts are hard to get. The vehicle was purchased new and was 7 months old and had just over 7,000 miles. The vehicle is still sitting at the dealership 10 days later and has not been moved from where it was delivered by the wrecker service. GM has been notified but no response from GM or dealership management yet as to what caused the engine failure. I occasionally tow a fifth-wheel rv with this vehicle. I no longer feel safe driving the vehicle and would not consider purchasing another until a determination is made on exactly what went wrong.
