The lock on the tailgate became difficult to lock. then, a week later while driving 35 mph down a city street, the tailgate dropped open. when i tried closing it, the left side would not latch. the tailgate handle was replaced a week later. this was the second time this part was replaced. this same thing happened in 2008 when it was still under warranty. *tr
