The rear corner panels on either side of the tailgate (black plastic) can crack or break. They should be cut off and the adhesive removed before new panels are glued on.
Electrical switches in the door latches can fail, causing the door locks to rapidly actuate up and down multiple times when the locks are activated by either the keyless remote or door lock switch. A new door latch will need to be installed.
