There is a very annoying loud banging noise at the back of the truck that was subtle when i bought the truck. The dealer's attention was called to it and they agreed to fix it. Four days later, i picked up the truck and the noise had significantly reduced. After running the truck for about four to six weeks, the noise came back and has been getting worse to the point were it's very annoying now.

Also, the engine runs very rough which i did not notice initially when buying the vehicle.
