Within 2 years of purchasing the vehicle, we began having problems with the passenger rear door latch mechanism. the device has a child safety lock (unsure if this is the problem). after jiggling the lock toggle in the vehicle and the child safety lock, the door would eventually unlock and allow you to open the door. this fix would remain temporary and occur often. then the same trouble moved to the opposite rear door. after owning the vehicle now for 8 years, both doors would lock at some point in time, together, or separately and sometimes unlock after vigorous attempts to unlock the toggle. now both doors will not unlock for us to open them. the problem is not with a linkage system that may have a broken plastic piece that holds the linkage rod. i checked that myself on several occasions. i have a 4 year old that has to crawl out of the front in order to get out. in the event of an accident, this delay or an inability to move on his own, could be detrimental. i told the dealer several time about it, but they were never really concerned and the mechanism seemed to work well with them, so they shrugged me off. the dealer has terrible service. overall, the truck has been great. but, i worry that we will not be able to get it open when needed in an emergency. i will be ordering my own parts and doing the repair myself. i can't trust the dealership and i am fed up with their lies and deceit. *tr
