Had this truck less than 2 weeks before the check engine light came on. Once the light came on it would display a message on the dash that said engine power is reduced since it wasn't getting the correct amount of fuel. The dealership looked it over and said it was fine to drive until the replacement part came in. It turns out it was not okay to drive. Leaving the store, it fell on it's face and I was almost rear-ended with my children in the truck. Here we are 10 days later, the service department manager said the part has shipped, another guy says it has not shipped. I am beginning to regret my decision to buy this truck. Come one General Motors, I thought you were top of the line.
