 This is my last update on our 2008 F-450.I no longer wish to own this vehicle.Do not buy a 2008, it will leave you broke!As I was driving my kids home after their karate practice, we noticed a strange clicking sound coming from the engine.The sound kept getting louder and louder so I was attempting to find a safe place to pull over in the middle of no where.Too late.The truck just suddenly shut off.I was told by our Ford service department today that we need a new engine.Cost: $16,000 or the other "cheaper" option is a partial rebuild at $14,000."Internal problem" is their diagnosis.So dissapointed in a truck I used to love.
