I've replaced mine three times, but we use our rear hatch more than most people use their passenger door (I installed the third seat option and use it daily for my little kids). I've not done the job; left it to a tech. However, this most recent time I also replaced the hatch's wiring harnesses, as they were beginning to act a bit weird.
